Hi all

I just found out how ...:

 - click the top-right tiny arrow of the BindingNavigator. The BindingNavigator Tasks pane pops up
 - click the top item in this, "Embed in ToolStripContainer"

A ToolStripContainer is created. Adjust the size of this or choose to dock it in the parent.
Now the BindingNavigator can be moved around inside the ToolStripContainer.

Hi William

Which control do you use for browsing records on forms? The default dataTableBindingNavigator?
If so, have you managed to undock it so it can float? I have the GripStyle set to Visible, but the toolstrip is not to grip and move around.

...yes, free!!! ...the express products value has been simply incredible for 
me ...I've yet to run into anything I could do with Access that I can't find 
a way to do with one or more of the express products ...and the 
amount/quality of code/support available on-line is every bit as good ...I 
still tend to model an app in Access first but I'm now starting to deliver 
in VS/SQL Server ...and the client sales are soooooo much easier in most 
cases.

Hi Everyone,

	In VB6, the following code sets/unsets the text box to bold
and/italic depending on the value of the checkboxes:
	txtMyText.Font.Bold = chkBold.Value
	txtMyText.Font.Italic = chkItalic.Value

	How do you do the same in VB2005?

Pete

I have created two tableadapters, a source and a target, and need to browse through the source looking for rows and, when a row meeting some conditions is found, copy this to the target.
What is the best method?

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

I think you need to follow with kunderT.Update to update the underlying database from the 
TableAdapter.

Hi Col and Denice,

The final version of the time detail report is in place.
I had to use the 'unscheduled' attribute to identify the OT.  So any
unscheduled OT will show in the ADJ/ENT column only.

Let me know if there are any problems.

FYI
We are moving offices tomorrow and we cant be sure when Telstra will
have the new phone lines ready
or when our internet connection will be available.  It is probably a
good idea to catch me on the mobile till
it gets sorted out.

regards

Hi Stuart

That is what I imagined initially.
Problem is, however and to my surprise, that neither a DataSet nor a DataTable features an Update method.

So what to do? 
I can't believe you have to revert to pure SQL commands to write back an update of a DataSet or DataTable??

Message-ID: <s7a9c475.014@cactus.dk>

Hi Stuart et al

Oh my, make a note on this should you ever wish to copy data between DataSets or DataTables with method ImportRow.

The secret is the value of property RowState of the individual rows. Rows read from a table have a RowState of Unchanged.
If a row is copied to another DataSet/DataTable by method ImportRow, RowState remains Unchanged.

In my code sample below, I marked rows as Modified with method SetModified.

The Update method of the DataTableAdapter, which is called to write the data rows to the underlying table, is quite clever as it doesn't touch rows with RowState Unchanged.
However, rows with RowState Modified will only be used to update existing records in the target table, thus it will not attempt to append or insert any such row. 

For a row to be inserted by the later Update call, it has to have RowState set to Added.

So, for my code below, I have to decide if a row should update an existing record, or if it should be appended, or if it should be ignored - and then call the method SetModified or SetAdded or nothing:

                    // Mark row as modified.
                    kundeRowS.SetModified();
or:
                    // Mark row as new.
                    kundeRowS.SetAdded();

When I changed the code from SetModified to SetAdded and replaced the Fill method with:

      kundeAdapterT.Update(kunderT);

all records were written to the target table.

Of course, if you can write your code to add rows not using method ImportRow - with LoadDataRow or like:

                    kunderT.Rows.Add(rowToAdd);

RowState of those rows, I guess, will be switched to Added automatically.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7aafb33.042@cactus.dk>

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after having browsed thousands of sites (so it feels). I thought it would be a simple job to locate code somewhere around that I could modify, but no. Well, yes, but that is basic code snippets working with connection strings and SQL commands and so on for ASP kiddies. This must be very special, though I thought it to be some kind of standard routine. But no.

So again, should you ever have a task like the subject to do, make a note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL Update command which raised the error when you finally call the Update method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_with_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a row of another type (remember, source and target are from different DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                // Write back to the database table the updated target DataTable.
                kundeAdapterT.Update(kunderT);
                // Call AcceptChanges if needed for further processing.
                // kunderT.AcceptChanges();

Still, if anyone have a better method, I'm all ears. This is by no means an expert area for me.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Subject: Re: [dba-VB] Copy tables: Update or insert rows ina
DataTableAdapter from another DataTableAdapter

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after
having browsed thousands of sites (so it feels). I thought it would be a
simple job to locate code somewhere around that I could modify, but no.
Well, yes, but that is basic code snippets working with connection
strings and SQL commands and so on for ASP kiddies. This must be very
special, though I thought it to be some kind of standard routine. But
no.

So again, should you ever have a task like the subject to do, make a
note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL
Update command which raised the error when you finally call the Update
method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1
records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_wit
h_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and
only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with
a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the
parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a
row of another type (remember, source and target are from different
DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows
in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter
kundeAdapterS =
                    new
VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter
kundeAdapterT =
                    new
VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in
kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the
RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target
row.
                        // This sets RowState of the target row to
Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would
clear property RowState.
                    }
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                // Write back to the database table the updated target
DataTable.
                kundeAdapterT.Update(kunderT);
                // Call AcceptChanges if needed for further processing.
                // kunderT.AcceptChanges();

Still, if anyone have a better method, I'm all ears. This is by no means
an expert area for me.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you copy a row by clearing the target first and then importing the source/remote row? But what does method Clear do here? As far as I know, Clear "erases" the row and leave it - it does not delete it.

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7ab9f96.061@cactus.dk>

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

Hi Charlotte

Thanks for that explanation, I can see why you do it this way.

My situation is somewhat different as no data will be live - the source is an Access mdb permanently linked to the SQL Server - and the import will be run at regular intervals. Thus, should a row or two be lost during an import they will be fetched at the next run.

As for the array compare, I will check out your idea of a temp table.

	a	DataTableAdapter from another DataTableAdapter

Hi Charlotte and Stuart et al

The hash code of a row cannot be used as it is based on the parent (name of DateTable or DataSet object) and the position of the row in this, not the content. And ToString of the ItemArray and other objects just returns the name of the object, not the content or value of it.

However, I located a very simple method to compare two arrays with "normal" content - not BLOBS or binaries - without having to code loops and so on.

Once again, the .Net framework came to rescue - this time with Concat which (also) is able to concatenate the rows of an array.
So:

            // DataTableAdapter to copy from.
            VrsSourceTableAdapters.DataTableOrdreTableAdapter ordreSAdapter =
                new VrsSourceTableAdapters.DataTableOrdreTableAdapter();
            VrsSource.DataTableOrdreDataTable ordreS;

            // DataTableAdapter to copy to.
            VrsTargetTableAdapters.DataTableOrdreTableAdapter ordreTAdapter =
                new VrsTargetTableAdapters.DataTableOrdreTableAdapter();
            VrsTarget.DataTableOrdreDataTable ordreT;

            // DataTable for source.
            ordreS = ordreSAdapter.GetDataVrsOrdrer();
            // DataTable for target.
            ordreT = ordreTAdapter.GetDataVrsOrdrer();

            // Read each row from the source rows.
            // Update those found in the target table.
            // Append those not found in the target table.

           // Variable to hold primary key to locate.
            Int32 key;
            // Create row to hold a found row in the target.
            VrsTarget.DataTableOrdreRow foundRow = null;
            // Variables to hold hash codes of row contents.
            int hashSource;
            int hashTarget;
            
            foreach (VrsSource.DataTableOrdreRow ordreSRow in ordreS)
            {
                // Value of primary key to locate.
                key = ordreSRow.ordreNr;
                // Find a matching row in the target.
                foundRow = ordreT.FindByOrdreNr(key);

                if (foundRow == null)
                {
                    // Row is not found. 
                    // Set the RowState of the source row as Added.
                    ordreSRow.SetAdded();
                    // Append it to the target preserving the RowState.
                    ordreT.ImportRow(ordreSRow);
                }
                else
                {
                    // Row is found.
                    Console.WriteLine("  Found: " + key.ToString());
                    // Calculate hash code to see if source row and target row match.
                    hashSource = String.Concat(ordreSRow.ItemArray).GetHashCode();
                    hashTarget = String.Concat(foundRow.ItemArray).GetHashCode();
                    Console.WriteLine(" - Hash: " + hashSource.ToString() + " - " + hashTarget.ToString());
                    if (hashSource != hashTarget)
                    {
                        // The source row is updated.
                        Console.WriteLine("  Modified OrdreNr: " + ordreSRow.ordreNr + "");
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = ordreSRow.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
            }

            // Write back to the database table the updated/appended rows of target DataTable.
            ordreTAdapter.Update(ordreT);


Of course, if you have juxtaposed columns with similar content like:

  Val1  Val2  Concatenated string
   3      44     344
  34      4      344

just concatenating these may in some cases fail as the right column shows, but that is not the case for my current task.

So now I only update modified records and append new records leaving the bunch of not modified records untouched!

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

This is more of an excel question but maybe someone can help.
 
Is there a way to do cell validation in Excel.
Something like an OnExit event where I can check a value after it's entered?

Hello John,

Excel.Worksheet object has several events related to Excel.Range:

Event Change(Target As Range)
Event SelectionChange(Target As Range)
Event BeforeDoubleClick(Target As Range, Cancel As Boolean)
Event BeforeRightClick(Target As Range, Cancel As Boolean)

You can try to explore and use these events...

Excel.Workbook object has a couple of useful events to implement validation
on whole worksheet/workbook level:

Event BeforeSave(SaveAsUI As Boolean, Cancel As Boolean)
Event BeforeClose(Cancel As Boolean)

Shamil,


I may be asking you a few questions over the next few days as I'm working on
a new project so if they are basic questions, bare with me.

I was successful in using the BeforeDoubleClick event on a 'sheet', but want
it to work for 'every sheet' without having to add the code to every sheet.

I tried the following at the 'workbook' level for testing and hoped it would
be global across all sheets. Am I thinking about this in the wrong way?

Here is the code:

Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target
As Range, Cancel As Boolean)
  MsgBox "The Target Is " & Target
  MsgBox "The Target Name Is " & Target.AddressLocal
End Sub

Hi al

How odd is this? I just took the time to install SQL Server 2008 Express CTP and VS2008 on a new machine (Vista) to enjoy a brave new world.
But as soon you attempt to connect to the server, this message pops:

"This server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported." 

They must be kidding ... even an add-on for VS2005 is available:

Any ideas on how to get it to accept SQL Server 2008 CTP?

should you receive the message:

If so, use this command to run the install where d is your cd drive:

	is	unavailable (Solution)
Message-ID: <s7af3efa.008@cactus.dk>

Hi all

When you try to connect to a linked database on a remote server, you will probably succeed.
However, when you try to preview the data (using the GetData.. method), you may receive this message just as data are to be retrieved:

  MSDTC on server 'servername' is unavailable

I found the solution here:

  http://geekswithblogs.net/narent/archive/2006/10/09/93544.aspx 

<quote>
Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Run MS DTC

If you have the application and the SQL Server Data base in two different machines you must do that also

Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Properties > MS DTC (TAB) > allow remote access 
</quote>

In my case, the MS DTC service was running - I just had to touch it as described to get it working.
Somewhat strange, I think, but who cares.

Also, I modified the hosts and lmhosts.sam files to include the name lookup of the remote server as this is not a server with a public URL, but I'm not sure if that really is necessary as VS previously was perfectly able to preview a table of a normal database (but not of a linked) on that same server.

hosts file:
xxx.xxx.xxx.xxx	servername		# Description of server

lmhosts.sam file:
xxx.xxx.xxx.xxx	servername	#PRE	#Description of server

True, but indeed I suspect this issue to be true also if the SQL Server 2008 is installed on a remote machine.

VS2008 seems to have very few issues running on Vista Business which is what I use.

            // DataTable for target.
            targetDataTable = targetDataTableAdapter.GetData();

If the underlying database connection needs a password, the code fails at the line with GetData().

Would I need to go all the way back to read the ConnectionString, modify this, and reapply? How?
Or is there a more clever method? At best like:

          targetDataTableAdapter.Connection.SetPassword("secret");

Message-ID: <s7bd7ddb.024@cactus.dk>

Hi all

OK, I found out. The DataTableAdapter has a Connection which has a ConnectionString property, and you can modify that using the SqlConnectionStringBuilder.

Here is for my targetDataTableAdapter:

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

  // Define password.
  string password = (string)"YourSecretPassword";
  // Retrieve connection string.
  SqlConnectionStringBuilder sqlConnectionStringBuilder = new SqlConnectionStringBuilder(); 
  sqlConnectionStringBuilder.ConnectionString = targetDataTableAdapter.Connection.ConnectionString;
  // Apply password to connection string.
  sqlConnectionStringBuilder.Password = password;
  // Apply the modifed connection.
  targetDataTableAdapter.Connection = new SqlConnection(sqlConnectionStringBuilder.ToString());

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

/gustav

Hi all

Is it possible at runtime to set the password for the connection when you open a DataTableAdapter?

I have code like this:

            // DataTableAdapter to copy from.
            RemoteTableAdapters.CompanyTableAdapter sourceDataTableAdapter =
                new RemoteTableAdapters.CompanyTableAdapter();
            Remote.CompanyDataTable sourceDataTable;

            // DataTableAdapter to copy to.
            LocalTableAdapters.CompanyTableAdapter targetDataTableAdapter =
                new LocalTableAdapters.CompanyTableAdapter();
            Local.CompanyDataTable targetDataTable;

            // DataTable for source.
            sourceDataTable = sourceDataTableAdapter.GetData();

Hi all

I browsed this tip from FMS and noticed at the bottom a way to view deleted rows of a DataSet should you wish to:

  http://www.fmsinc.com/free/NewTips/NET/NETtip56.asp 

'in order to access the values from the deleted row you can create a filtered dataview

  Debug.WriteLine("Retrieve the values of deleted rows")

  Dim dv As New DataView(dt, "", "", DataViewRowState.Deleted)

  For Each drv As DataRowView In dv
    Debug.WriteLine("ID: " & drv.Item("ID").ToString & _

You can also read the data from a deleted DataRow on a field by field
basis, but it's a little different:


If myRow.RowState = DataRowState.Deleted Then
	strVal = myRow.Item("Field1", DataRowVersion.Original).ToString
Else
	strVal = myRow.Field1
End If


We use this when we need to do something like renumber a sequence value
in an array of DataRows where one or more has been deleted.

Hi John

I had a look but unfortunately it seems as your demo form only deals with the settings for the form.

What I am after is an option to - from code - not only read but also write the application settings as shown on tab Settings when you open the project's Properties from menu Project (bottom entry).
These can be read easily but only written to if you attack the underlying XML file which I don't like - I mean, if the settings are read-only it is for a reason, though dull.

So I wondered what others do to persistently save various application settings?

Setting Values at Run Time

Some applications are built with administration tools that can update the
application's settings.  In ASP.NET 2.0, we can modify settings in the
web.config in our code.  This is something we would want to do in response
to a button's click event.  The sample code below shows how easy it is to
modify an application setting in ASP.NET 2.0.

Listing 8

Protected Sub btnUpdateSetting_Click(ByVal sender AsObject, ByVal e As
System.EventArgs) _
 Handles btnUpdateSetting.Click
 
Dim cfg As Configuration
cfg = WebConfigurationManager.OpenWebConfiguration("~")
 
Dim setting As KeyValueConfigurationElement = _
CType(cfg.AppSettings.Settings("MySetting"),KeyValueConfigurationElement)
 
If Not setting Is Nothing Then
  setting.Value = "New Value Setting"
  cfg.Save()
End If
End Sub

Are you talking about settings for Visual Studio or settings for an
application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi Charlotte

It is the app.config xml file for application settings like Connection strings and so on:

  C:\...\Visual Studio 2005\Projects\<project>\<project>\app.config

It holds the entries from the menu Project, <project> Properties pane, tab Settings.

Nothing wrong with XML files. It's just that it seems that this file is for VS's use, so don't tamper with it.

If you reference System.Configuration you can easily read from it via code, and methods exists for editing and saving values for _users_, however nothing can be saved for the _application_:

OK, you've totally lost me.  We don't reference either of those files,
and why should we?  All (or virtually all) of the contents are created
as we build the application.  The only time we modify our app.config is
to handle a DataDynamics licensing issue on our onw workstations.  Geeks
notwithstanding, settings only apply at runtime, and we can control
those nicely with xml files.  We store our connection strings in an xml
file, not in app.config, and read them when we need them.  Obviously,
userIDs and passwords are NOT stored in the xml file.

I still have the feeling we're talking about two different things here.

Hi Charlotte

It is the app.config xml file for application settings like Connection
strings and so on:

  C:\...\Visual Studio 2005\Projects\<project>\<project>\app.config

It holds the entries from the menu Project, <project> Properties pane,
tab Settings.

Nothing wrong with XML files. It's just that it seems that this file is
for VS's use, so don't tamper with it.

If you reference System.Configuration you can easily read from it via
code, and methods exists for editing and saving values for _users_,
however nothing can be saved for the _application_:

Are you talking about settings for Visual Studio or settings for an
application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi all

How do you store application settings?

I've noticed the nice pane with the tab "Settings" for manually doing
this, but it is read-only from code.
Of course you can step down and attack the xml file storing the data,
but I find that a bit clumsy.

Hi Charlotte et al

OK, I'm a child of VS2005, and when creating data sources the wizard kindly asks if you wish to save the connection strings in a file. Yes please, and that file happens to be app.config which you can read and write via the GUI.

Now I realize that this file has entries for application settings as well as user settings where the main difference is that the application settings are read-only during runtime. This, of course, limits the value of using the application settings as you may have a need to store or edit application setting entries during runtime.
I don't like to reinvent the wheel so I wondered if any method exists to circumvent this limitation other than to create a separate system as you have done. The only method I have seen is to open the app.config XML file directly as any other XML file:

  http://www.ryanfarley.com/blog/archive/2004/07/13/879.aspx 

To complicate matters, an advice is _not_ to do that because - as I mentioned previously - if the app.config file is read-only, it might be for a reason. That reason is explained here:

  http://www.interact-sw.co.uk/iangblog/2004/11/25/savingconfig 

where the author claims that one should never write files into the Program Files folder ..(!) .. but use the Application Data folder of the user.
That may be true, and I sure want to behave, but the next question is then: Where to store config files and such common for all users? Would that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

/gustav


>>> cfoust at infostatsystems.com 28-02-2008 18:28 >>>
OK, you've totally lost me.  We don't reference either of those files,
and why should we?  All (or virtually all) of the contents are created
as we build the application.  The only time we modify our app.config is
to handle a DataDynamics licensing issue on our onw workstations.  Geeks
notwithstanding, settings only apply at runtime, and we can control
those nicely with xml files.  We store our connection strings in an xml
file, not in app.config, and read them when we need them.  Obviously,
userIDs and passwords are NOT stored in the xml file.

I still have the feeling we're talking about two different things here.

Storing stuff in the registry is definitely discouraged in dotNet,
Susan.  And more and more, the registry is being locked down by system
administrator.  We started to run into problems with that in our extant
Access applications.

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

I think you need to follow with kunderT.Update to update the underlying database from the 
TableAdapter.

Hi Col and Denice,

The final version of the time detail report is in place.
I had to use the 'unscheduled' attribute to identify the OT.  So any
unscheduled OT will show in the ADJ/ENT column only.

Let me know if there are any problems.

FYI
We are moving offices tomorrow and we cant be sure when Telstra will
have the new phone lines ready
or when our internet connection will be available.  It is probably a
good idea to catch me on the mobile till
it gets sorted out.

regards

Hi Stuart

That is what I imagined initially.
Problem is, however and to my surprise, that neither a DataSet nor a DataTable features an Update method.

So what to do? 
I can't believe you have to revert to pure SQL commands to write back an update of a DataSet or DataTable??

Subject: [dba-VB] Copy tables
Message-ID: <s7a9c475.014@cactus.dk>

Hi Stuart et al

Oh my, make a note on this should you ever wish to copy data between DataSets or DataTables with method ImportRow.

The secret is the value of property RowState of the individual rows. Rows read from a table have a RowState of Unchanged.
If a row is copied to another DataSet/DataTable by method ImportRow, RowState remains Unchanged.

In my code sample below, I marked rows as Modified with method SetModified.

The Update method of the DataTableAdapter, which is called to write the data rows to the underlying table, is quite clever as it doesn't touch rows with RowState Unchanged.
However, rows with RowState Modified will only be used to update existing records in the target table, thus it will not attempt to append or insert any such row. 

For a row to be inserted by the later Update call, it has to have RowState set to Added.

So, for my code below, I have to decide if a row should update an existing record, or if it should be appended, or if it should be ignored - and then call the method SetModified or SetAdded or nothing:

                    // Mark row as modified.
                    kundeRowS.SetModified();
or:
                    // Mark row as new.
                    kundeRowS.SetAdded();

When I changed the code from SetModified to SetAdded and replaced the Fill method with:

      kundeAdapterT.Update(kunderT);

all records were written to the target table.

Of course, if you can write your code to add rows not using method ImportRow - with LoadDataRow or like:

                    kunderT.Rows.Add(rowToAdd);

RowState of those rows, I guess, will be switched to Added automatically.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7aafb33.042@cactus.dk>

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after having browsed thousands of sites (so it feels). I thought it would be a simple job to locate code somewhere around that I could modify, but no. Well, yes, but that is basic code snippets working with connection strings and SQL commands and so on for ASP kiddies. This must be very special, though I thought it to be some kind of standard routine. But no.

So again, should you ever have a task like the subject to do, make a note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL Update command which raised the error when you finally call the Update method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_with_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a row of another type (remember, source and target are from different DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                // Write back to the database table the updated target DataTable.
                kundeAdapterT.Update(kunderT);
                // Call AcceptChanges if needed for further processing.
                // kunderT.AcceptChanges();

Still, if anyone have a better method, I'm all ears. This is by no means an expert area for me.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after
having browsed thousands of sites (so it feels). I thought it would be a
simple job to locate code somewhere around that I could modify, but no.
Well, yes, but that is basic code snippets working with connection
strings and SQL commands and so on for ASP kiddies. This must be very
special, though I thought it to be some kind of standard routine. But
no.

So again, should you ever have a task like the subject to do, make a
note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL
Update command which raised the error when you finally call the Update
method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1
records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_wit
h_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and
only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with
a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the
parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a
row of another type (remember, source and target are from different
DataTableAdapters) is to copy the ItemArray.

                // Call AcceptChanges if needed for further processing.
                // kunderT.AcceptChanges();

Still, if anyone have a better method, I'm all ears. This is by no means
an expert area for me.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you copy a row by clearing the target first and then importing the source/remote row? But what does method Clear do here? As far as I know, Clear "erases" the row and leave it - it does not delete it.

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

Message-ID: <s7ac19c1.068@cactus.dk>

Hi Charlotte

Thanks for that explanation, I can see why you do it this way.

My situation is somewhat different as no data will be live - the source is an Access mdb permanently linked to the SQL Server - and the import will be run at regular intervals. Thus, should a row or two be lost during an import they will be fetched at the next run.

As for the array compare, I will check out your idea of a temp table.

/gustav

I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call
the Update method of the DataTableAdapter which causes a roundtrip to
the database server. 
I was looking for a method to update the complete DateTable (or DataSet)
and then save the complete collection of updated/appended rows in on go.


However, right now my code saves the complete DataTable as all existing
rows are updated. I'm looking for method to check if a row actually is
changed or not. As the target and source rows come from two different
DataTableAdapters I cannot use Equal. It seems I have to compare the
content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the
fields - to compare two arrays.
Any suggestions?

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7ac946f.095@cactus.dk>

Hi Charlotte and Stuart et al

The hash code of a row cannot be used as it is based on the parent (name of DateTable or DataSet object) and the position of the row in this, not the content. And ToString of the ItemArray and other objects just returns the name of the object, not the content or value of it.

However, I located a very simple method to compare two arrays with "normal" content - not BLOBS or binaries - without having to code loops and so on.

Once again, the .Net framework came to rescue - this time with Concat which (also) is able to concatenate the rows of an array.
So:

            // DataTableAdapter to copy from.
            VrsSourceTableAdapters.DataTableOrdreTableAdapter ordreSAdapter =
                new VrsSourceTableAdapters.DataTableOrdreTableAdapter();
            VrsSource.DataTableOrdreDataTable ordreS;

            // DataTableAdapter to copy to.
            VrsTargetTableAdapters.DataTableOrdreTableAdapter ordreTAdapter =
                new VrsTargetTableAdapters.DataTableOrdreTableAdapter();
            VrsTarget.DataTableOrdreDataTable ordreT;

            // DataTable for source.
            ordreS = ordreSAdapter.GetDataVrsOrdrer();
            // DataTable for target.
            ordreT = ordreTAdapter.GetDataVrsOrdrer();

            // Read each row from the source rows.
            // Update those found in the target table.
            // Append those not found in the target table.

           // Variable to hold primary key to locate.
            Int32 key;
            // Create row to hold a found row in the target.
            VrsTarget.DataTableOrdreRow foundRow = null;
            // Variables to hold hash codes of row contents.
            int hashSource;
            int hashTarget;
            
            foreach (VrsSource.DataTableOrdreRow ordreSRow in ordreS)
            {
                // Value of primary key to locate.
                key = ordreSRow.ordreNr;
                // Find a matching row in the target.
                foundRow = ordreT.FindByOrdreNr(key);

                if (foundRow == null)
                {
                    // Row is not found. 
                    // Set the RowState of the source row as Added.
                    ordreSRow.SetAdded();
                    // Append it to the target preserving the RowState.
                    ordreT.ImportRow(ordreSRow);
                }
                else
                {
                    // Row is found.
                    Console.WriteLine("  Found: " + key.ToString());
                    // Calculate hash code to see if source row and target row match.
                    hashSource = String.Concat(ordreSRow.ItemArray).GetHashCode();
                    hashTarget = String.Concat(foundRow.ItemArray).GetHashCode();
                    Console.WriteLine(" - Hash: " + hashSource.ToString() + " - " + hashTarget.ToString());
                    if (hashSource != hashTarget)
                    {
                        // The source row is updated.
                        Console.WriteLine("  Modified OrdreNr: " + ordreSRow.ordreNr + "");
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = ordreSRow.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
            }

            // Write back to the database table the updated/appended rows of target DataTable.
            ordreTAdapter.Update(ordreT);


Of course, if you have juxtaposed columns with similar content like:

  Val1  Val2  Concatenated string
   3      44     344
  34      4      344

just concatenating these may in some cases fail as the right column shows, but that is not the case for my current task.

So now I only update modified records and append new records leaving the bunch of not modified records untouched!

Hello John,

Excel.Worksheet object has several events related to Excel.Range:

Event Change(Target As Range)
Event SelectionChange(Target As Range)
Event BeforeDoubleClick(Target As Range, Cancel As Boolean)
Event BeforeRightClick(Target As Range, Cancel As Boolean)

You can try to explore and use these events...

Excel.Workbook object has a couple of useful events to implement validation
on whole worksheet/workbook level:

Event BeforeSave(SaveAsUI As Boolean, Cancel As Boolean)
Event BeforeClose(Cancel As Boolean)

I may be asking you a few questions over the next few days as I'm working on
a new project so if they are basic questions, bare with me.

I was successful in using the BeforeDoubleClick event on a 'sheet', but want
it to work for 'every sheet' without having to add the code to every sheet.

I tried the following at the 'workbook' level for testing and hoped it would
be global across all sheets. Am I thinking about this in the wrong way?

Here is the code:

Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target
As Range, Cancel As Boolean)
  MsgBox "The Target Is " & Target
  MsgBox "The Target Name Is " & Target.AddressLocal
End Sub

Hi al

How odd is this? I just took the time to install SQL Server 2008 Express CTP and VS2008 on a new machine (Vista) to enjoy a brave new world.
But as soon you attempt to connect to the server, this message pops:

Hi all

Found this tip which can save you a lot of time and lost hair:

  http://codingreflection.com/wordpress/?p=371

should you receive the message:

  "None of the selected features can be installed or upgraded."

If so, use this command to run the install where d is your cd drive:

d:\setup.exe SKUUPGRADE=1

For Visual Studio 2008 to support SQL Server 2008, we will be delivering a patch to coincide with the next CTP of SQL Server 2008.

which raises the logical question:

The next CTP of SQL Server 2008 will likely come out towards the end of Feburary - in time for the "VS2008, Windows Server 2008 and SQL Server 2008" launch.

Subject: [dba-VB] Visual Studio 2008: MSDTC on server 'servername'
	is	unavailable (Solution)
Message-ID: <s7af3efa.008@cactus.dk>

Hi all

When you try to connect to a linked database on a remote server, you will probably succeed.
However, when you try to preview the data (using the GetData.. method), you may receive this message just as data are to be retrieved:

  MSDTC on server 'servername' is unavailable

I found the solution here:

  http://geekswithblogs.net/narent/archive/2006/10/09/93544.aspx 

<quote>
Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Run MS DTC

If you have the application and the SQL Server Data base in two different machines you must do that also

Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Properties > MS DTC (TAB) > allow remote access 
</quote>

In my case, the MS DTC service was running - I just had to touch it as described to get it working.
Somewhat strange, I think, but who cares.

Also, I modified the hosts and lmhosts.sam files to include the name lookup of the remote server as this is not a server with a public URL, but I'm not sure if that really is necessary as VS previously was perfectly able to preview a table of a normal database (but not of a linked) on that same server.

hosts file:
xxx.xxx.xxx.xxx	servername		# Description of server

lmhosts.sam file:
xxx.xxx.xxx.xxx	servername	#PRE	#Description of server

True, but indeed I suspect this issue to be true also if the SQL Server 2008 is installed on a remote machine.

VS2008 seems to have very few issues running on Vista Business which is what I use.

Subject: [dba-VB] How to set password for a DataTable(Adapter)'s connection?
Message-ID: <s7bc9003.006@cactus.dk>

Hi all

Is it possible at runtime to set the password for the connection when you open a DataTableAdapter?

I have code like this:

            // DataTableAdapter to copy from.
            RemoteTableAdapters.CompanyTableAdapter sourceDataTableAdapter =
                new RemoteTableAdapters.CompanyTableAdapter();
            Remote.CompanyDataTable sourceDataTable;

            // DataTableAdapter to copy to.
            LocalTableAdapters.CompanyTableAdapter targetDataTableAdapter =
                new LocalTableAdapters.CompanyTableAdapter();
            Local.CompanyDataTable targetDataTable;

            // DataTable for source.
            sourceDataTable = sourceDataTableAdapter.GetData();
            // DataTable for target.
            targetDataTable = targetDataTableAdapter.GetData();

If the underlying database connection needs a password, the code fails at the line with GetData().

Would I need to go all the way back to read the ConnectionString, modify this, and reapply? How?
Or is there a more clever method? At best like:

          targetDataTableAdapter.Connection.SetPassword("secret");

OK, I found out. The DataTableAdapter has a Connection which has a ConnectionString property, and you can modify that using the SqlConnectionStringBuilder.

Here is for my targetDataTableAdapter:

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

  // Define password.
  string password = (string)"YourSecretPassword";
  // Retrieve connection string.
  SqlConnectionStringBuilder sqlConnectionStringBuilder = new SqlConnectionStringBuilder(); 
  sqlConnectionStringBuilder.ConnectionString = targetDataTableAdapter.Connection.ConnectionString;
  // Apply password to connection string.
  sqlConnectionStringBuilder.Password = password;
  // Apply the modifed connection.
  targetDataTableAdapter.Connection = new SqlConnection(sqlConnectionStringBuilder.ToString());

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

  http://www.fmsinc.com/free/NewTips/NET/NETtip56.asp 

'in order to access the values from the deleted row you can create a filtered dataview

  Debug.WriteLine("Retrieve the values of deleted rows")

  Dim dv As New DataView(dt, "", "", DataViewRowState.Deleted)

You can also read the data from a deleted DataRow on a field by field
basis, but it's a little different:


If myRow.RowState = DataRowState.Deleted Then
	strVal = myRow.Item("Field1", DataRowVersion.Original).ToString
Else
	strVal = myRow.Field1
End If


We use this when we need to do something like renumber a sequence value
in an array of DataRows where one or more has been deleted.

Hi all

How do you store application settings?

I've noticed the nice pane with the tab "Settings" for manually doing this, but it is read-only from code.
Of course you can step down and attack the xml file storing the data, but I find that a bit clumsy.

Hi John

Well, that is what I thought. But it is read-only. Has to be edited manually via the GUI.

Hi John

I had a look but unfortunately it seems as your demo form only deals with the settings for the form.

What I am after is an option to - from code - not only read but also write the application settings as shown on tab Settings when you open the project's Properties from menu Project (bottom entry).
These can be read easily but only written to if you attack the underlying XML file which I don't like - I mean, if the settings are read-only it is for a reason, though dull.

So I wondered what others do to persistently save various application settings?

Setting Values at Run Time

Some applications are built with administration tools that can update the
application's settings.  In ASP.NET 2.0, we can modify settings in the
web.config in our code.  This is something we would want to do in response
to a button's click event.  The sample code below shows how easy it is to
modify an application setting in ASP.NET 2.0.

Listing 8

Protected Sub btnUpdateSetting_Click(ByVal sender AsObject, ByVal e As
System.EventArgs) _
 Handles btnUpdateSetting.Click
 
Dim cfg As Configuration
cfg = WebConfigurationManager.OpenWebConfiguration("~")
 
Dim setting As KeyValueConfigurationElement = _
CType(cfg.AppSettings.Settings("MySetting"),KeyValueConfigurationElement)
 
If Not setting Is Nothing Then
  setting.Value = "New Value Setting"
  cfg.Save()
End If
End Sub

Are you talking about settings for Visual Studio or settings for an
application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi Charlotte

It is the app.config xml file for application settings like Connection strings and so on:

  C:\...\Visual Studio 2005\Projects\<project>\<project>\app.config

It holds the entries from the menu Project, <project> Properties pane, tab Settings.

Nothing wrong with XML files. It's just that it seems that this file is for VS's use, so don't tamper with it.

If you reference System.Configuration you can easily read from it via code, and methods exists for editing and saving values for _users_, however nothing can be saved for the _application_:

OK, you've totally lost me.  We don't reference either of those files,
and why should we?  All (or virtually all) of the contents are created
as we build the application.  The only time we modify our app.config is
to handle a DataDynamics licensing issue on our onw workstations.  Geeks
notwithstanding, settings only apply at runtime, and we can control
those nicely with xml files.  We store our connection strings in an xml
file, not in app.config, and read them when we need them.  Obviously,
userIDs and passwords are NOT stored in the xml file.

I still have the feeling we're talking about two different things here.

Hi Charlotte et al

OK, I'm a child of VS2005, and when creating data sources the wizard kindly asks if you wish to save the connection strings in a file. Yes please, and that file happens to be app.config which you can read and write via the GUI.

Now I realize that this file has entries for application settings as well as user settings where the main difference is that the application settings are read-only during runtime. This, of course, limits the value of using the application settings as you may have a need to store or edit application setting entries during runtime.
I don't like to reinvent the wheel so I wondered if any method exists to circumvent this limitation other than to create a separate system as you have done. The only method I have seen is to open the app.config XML file directly as any other XML file:

  http://www.ryanfarley.com/blog/archive/2004/07/13/879.aspx 

To complicate matters, an advice is _not_ to do that because - as I mentioned previously - if the app.config file is read-only, it might be for a reason. That reason is explained here:

  http://www.interact-sw.co.uk/iangblog/2004/11/25/savingconfig 

where the author claims that one should never write files into the Program Files folder ..(!) .. but use the Application Data folder of the user.
That may be true, and I sure want to behave, but the next question is then: Where to store config files and such common for all users? Would that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

individual settings in the registry.

Storing stuff in the registry is definitely discouraged in dotNet,
Susan.  And more and more, the registry is being locked down by system
administrator.  We started to run into problems with that in our extant
Access applications.

Hi all

Again, pressing Send helps assimilation. 
Just browsed to the last paragraph of the link. Calling:

 
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationDat
a)

returns on my machine:

  "C:\\Documents and Settings\\All Users\\Application Data"

Is that the answer?

where the author claims that one should never write files into the
Program Files folder ..(!) .. but use the Application Data folder of the
user.
That may be true, and I sure want to behave, but the next question is
then: Where to store config files and such common for all users? Would
that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

Hi all

I just found out how ...:

 - click the top-right tiny arrow of the BindingNavigator. The BindingNavigator Tasks pane pops up
 - click the top item in this, "Embed in ToolStripContainer"

A ToolStripContainer is created. Adjust the size of this or choose to dock it in the parent.
Now the BindingNavigator can be moved around inside the ToolStripContainer.

Hi William

Which control do you use for browsing records on forms? The default dataTableBindingNavigator?
If so, have you managed to undock it so it can float? I have the GripStyle set to Visible, but the toolstrip is not to grip and move around.

	In VB6, the following code sets/unsets the text box to bold
and/italic depending on the value of the checkboxes:
	txtMyText.Font.Bold = chkBold.Value
	txtMyText.Font.Italic = chkItalic.Value

	How do you do the same in VB2005?

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

I think you need to follow with kunderT.Update to update the underlying database from the 
TableAdapter.

Hi Col and Denice,

The final version of the time detail report is in place.
I had to use the 'unscheduled' attribute to identify the OT.  So any
unscheduled OT will show in the ADJ/ENT column only.

Let me know if there are any problems.

FYI
We are moving offices tomorrow and we cant be sure when Telstra will
have the new phone lines ready
or when our internet connection will be available.  It is probably a
good idea to catch me on the mobile till
it gets sorted out.

regards

Hi Stuart

That is what I imagined initially.
Problem is, however and to my surprise, that neither a DataSet nor a DataTable features an Update method.

So what to do? 
I can't believe you have to revert to pure SQL commands to write back an update of a DataSet or DataTable??

Subject: [dba-VB] Copy tables
Message-ID: <s7a9c475.014@cactus.dk>

Hi Stuart et al

Oh my, make a note on this should you ever wish to copy data between DataSets or DataTables with method ImportRow.

The secret is the value of property RowState of the individual rows. Rows read from a table have a RowState of Unchanged.
If a row is copied to another DataSet/DataTable by method ImportRow, RowState remains Unchanged.

In my code sample below, I marked rows as Modified with method SetModified.

The Update method of the DataTableAdapter, which is called to write the data rows to the underlying table, is quite clever as it doesn't touch rows with RowState Unchanged.
However, rows with RowState Modified will only be used to update existing records in the target table, thus it will not attempt to append or insert any such row. 

For a row to be inserted by the later Update call, it has to have RowState set to Added.

So, for my code below, I have to decide if a row should update an existing record, or if it should be appended, or if it should be ignored - and then call the method SetModified or SetAdded or nothing:

                    // Mark row as modified.
                    kundeRowS.SetModified();
or:
                    // Mark row as new.
                    kundeRowS.SetAdded();

When I changed the code from SetModified to SetAdded and replaced the Fill method with:

      kundeAdapterT.Update(kunderT);

all records were written to the target table.

Of course, if you can write your code to add rows not using method ImportRow - with LoadDataRow or like:

                    kunderT.Rows.Add(rowToAdd);

RowState of those rows, I guess, will be switched to Added automatically.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7aafb33.042@cactus.dk>

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after having browsed thousands of sites (so it feels). I thought it would be a simple job to locate code somewhere around that I could modify, but no. Well, yes, but that is basic code snippets working with connection strings and SQL commands and so on for ASP kiddies. This must be very special, though I thought it to be some kind of standard routine. But no.

So again, should you ever have a task like the subject to do, make a note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL Update command which raised the error when you finally call the Update method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_with_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a row of another type (remember, source and target are from different DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Subject: Re: [dba-VB] Copy tables: Update or insert rows ina
DataTableAdapter from another DataTableAdapter

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after
having browsed thousands of sites (so it feels). I thought it would be a
simple job to locate code somewhere around that I could modify, but no.
Well, yes, but that is basic code snippets working with connection
strings and SQL commands and so on for ASP kiddies. This must be very
special, though I thought it to be some kind of standard routine. But
no.

So again, should you ever have a task like the subject to do, make a
note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL
Update command which raised the error when you finally call the Update
method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1
records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_wit
h_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and
only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with
a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the
parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a
row of another type (remember, source and target are from different
DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows
in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter
kundeAdapterS =
                    new
VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter
kundeAdapterT =
                    new
VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in
kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the
RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target
row.
                        // This sets RowState of the target row to
Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would
clear property RowState.
                    }
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you copy a row by clearing the target first and then importing the source/remote row? But what does method Clear do here? As far as I know, Clear "erases" the row and leave it - it does not delete it.

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

Message-ID: <s7ab9f96.061@cactus.dk>

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

Hi Charlotte

Thanks for that explanation, I can see why you do it this way.

My situation is somewhat different as no data will be live - the source is an Access mdb permanently linked to the SQL Server - and the import will be run at regular intervals. Thus, should a row or two be lost during an import they will be fetched at the next run.

As for the array compare, I will check out your idea of a temp table.

Hi Charlotte and Stuart et al

The hash code of a row cannot be used as it is based on the parent (name of DateTable or DataSet object) and the position of the row in this, not the content. And ToString of the ItemArray and other objects just returns the name of the object, not the content or value of it.

However, I located a very simple method to compare two arrays with "normal" content - not BLOBS or binaries - without having to code loops and so on.

Once again, the .Net framework came to rescue - this time with Concat which (also) is able to concatenate the rows of an array.
So:

            // DataTableAdapter to copy from.
            VrsSourceTableAdapters.DataTableOrdreTableAdapter ordreSAdapter =
                new VrsSourceTableAdapters.DataTableOrdreTableAdapter();
            VrsSource.DataTableOrdreDataTable ordreS;

            // DataTableAdapter to copy to.
            VrsTargetTableAdapters.DataTableOrdreTableAdapter ordreTAdapter =
                new VrsTargetTableAdapters.DataTableOrdreTableAdapter();
            VrsTarget.DataTableOrdreDataTable ordreT;

            // DataTable for source.
            ordreS = ordreSAdapter.GetDataVrsOrdrer();
            // DataTable for target.
            ordreT = ordreTAdapter.GetDataVrsOrdrer();

            // Read each row from the source rows.
            // Update those found in the target table.
            // Append those not found in the target table.

           // Variable to hold primary key to locate.
            Int32 key;
            // Create row to hold a found row in the target.
            VrsTarget.DataTableOrdreRow foundRow = null;
            // Variables to hold hash codes of row contents.
            int hashSource;
            int hashTarget;
            
            foreach (VrsSource.DataTableOrdreRow ordreSRow in ordreS)
            {
                // Value of primary key to locate.
                key = ordreSRow.ordreNr;
                // Find a matching row in the target.
                foundRow = ordreT.FindByOrdreNr(key);

                if (foundRow == null)
                {
                    // Row is not found.

                    ordreSRow.SetAdded();
                    // Append it to the target preserving the RowState.
                    ordreT.ImportRow(ordreSRow);
                }
                else
                {
                    // Row is found.
                    Console.WriteLine("  Found: " + key.ToString());
                    // Calculate hash code to see if source row and target row match.
                    hashSource = String.Concat(ordreSRow.ItemArray).GetHashCode();
                    hashTarget = String.Concat(foundRow.ItemArray).GetHashCode();

                        Console.WriteLine("  Modified OrdreNr: " + ordreSRow.ordreNr + "");
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = ordreSRow.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
            }

            // Write back to the database table the updated/appended rows of target DataTable.
            ordreTAdapter.Update(ordreT);


Of course, if you have juxtaposed columns with similar content like:

  Val1  Val2  Concatenated string
   3      44     344
  34      4      344

just concatenating these may in some cases fail as the right column shows, but that is not the case for my current task.

So now I only update modified records and append new records leaving the bunch of not modified records untouched!

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Is there a way to do cell validation in Excel.
Something like an OnExit event where I can check a value after it's entered?

Hello John,

Excel.Worksheet object has several events related to Excel.Range:

Event Change(Target As Range)
Event SelectionChange(Target As Range)
Event BeforeDoubleClick(Target As Range, Cancel As Boolean)
Event BeforeRightClick(Target As Range, Cancel As Boolean)

You can try to explore and use these events...

Excel.Workbook object has a couple of useful events to implement validation
on whole worksheet/workbook level:

Event BeforeSave(SaveAsUI As Boolean, Cancel As Boolean)
Event BeforeClose(Cancel As Boolean)

Shamil,


I may be asking you a few questions over the next few days as I'm working on
a new project so if they are basic questions, bare with me.

I was successful in using the BeforeDoubleClick event on a 'sheet', but want
it to work for 'every sheet' without having to add the code to every sheet.

I tried the following at the 'workbook' level for testing and hoped it would
be global across all sheets. Am I thinking about this in the wrong way?

Here is the code:

Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target
As Range, Cancel As Boolean)
  MsgBox "The Target Is " & Target
  MsgBox "The Target Name Is " & Target.AddressLocal
End Sub

Hi al

How odd is this? I just took the time to install SQL Server 2008 Express CTP and VS2008 on a new machine (Vista) to enjoy a brave new world.
But as soon you attempt to connect to the server, this message pops:

"This server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported."

Any ideas on how to get it to accept SQL Server 2008 CTP?

should you receive the message:

If so, use this command to run the install where d is your cd drive:

Hi all

When you try to connect to a linked database on a remote server, you will probably succeed.
However, when you try to preview the data (using the GetData.. method), you may receive this message just as data are to be retrieved:

  MSDTC on server 'servername' is unavailable

I found the solution here:

  http://geekswithblogs.net/narent/archive/2006/10/09/93544.aspx 

<quote>
Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Run MS DTC

If you have the application and the SQL Server Data base in two different machines you must do that also

Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Properties > MS DTC (TAB) > allow remote access 
</quote>

In my case, the MS DTC service was running - I just had to touch it as described to get it working.
Somewhat strange, I think, but who cares.

Also, I modified the hosts and lmhosts.sam files to include the name lookup of the remote server as this is not a server with a public URL, but I'm not sure if that really is necessary as VS previously was perfectly able to preview a table of a normal database (but not of a linked) on that same server.

hosts file:
xxx.xxx.xxx.xxx	servername		# Description of server

lmhosts.sam file:
xxx.xxx.xxx.xxx	servername	#PRE	#Description of server

True, but indeed I suspect this issue to be true also if the SQL Server 2008 is installed on a remote machine.

VS2008 seems to have very few issues running on Vista Business which is what I use.

I need a quick Web application... ala Access.

The main menu should include the following


Links to a page that allows me to add/edit  Questions, Names, Companies, and
finally Add the Survey Questions.

I have my demo in Access and they want the webpage ready tomorrow... a quick
and dirty page would make all the difference,  Any way to get this off the
ground super quick ala a quick wizard? :D I know i'm grasping at straws
but.. any help is appreciated.

Microsoft is giving students free access to its most sophisticated tools for
writing software and making media-rich websites, a move that intensifies its
competition with Adobe Systems and could challenge open source software's
popularity.

The Redmond-based software maker said late Monday it will let students
download Visual Studio Professional Edition, a software development

Subject: [dba-VB] How to set password for a DataTable(Adapter)'s connection?
Message-ID: <s7bc9003.006@cactus.dk>

Hi all

Is it possible at runtime to set the password for the connection when you open a DataTableAdapter?

I have code like this:

            // DataTableAdapter to copy from.
            RemoteTableAdapters.CompanyTableAdapter sourceDataTableAdapter =
                new RemoteTableAdapters.CompanyTableAdapter();
            Remote.CompanyDataTable sourceDataTable;

            // DataTableAdapter to copy to.
            LocalTableAdapters.CompanyTableAdapter targetDataTableAdapter =
                new LocalTableAdapters.CompanyTableAdapter();
            Local.CompanyDataTable targetDataTable;

            // DataTable for source.
            sourceDataTable = sourceDataTableAdapter.GetData();
            // DataTable for target.
            targetDataTable = targetDataTableAdapter.GetData();

If the underlying database connection needs a password, the code fails at the line with GetData().

Would I need to go all the way back to read the ConnectionString, modify this, and reapply? How?
Or is there a more clever method? At best like:

          targetDataTableAdapter.Connection.SetPassword("secret");

Hi all

OK, I found out. The DataTableAdapter has a Connection which has a ConnectionString property, and you can modify that using the SqlConnectionStringBuilder.

Here is for my targetDataTableAdapter:

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

  // Define password.
  string password = (string)"YourSecretPassword";
  // Retrieve connection string.
  SqlConnectionStringBuilder sqlConnectionStringBuilder = new SqlConnectionStringBuilder(); 
  sqlConnectionStringBuilder.ConnectionString = targetDataTableAdapter.Connection.ConnectionString;
  // Apply password to connection string.
  sqlConnectionStringBuilder.Password = password;
  // Apply the modifed connection.
  targetDataTableAdapter.Connection = new SqlConnection(sqlConnectionStringBuilder.ToString());

  Console.WriteLine(targetDataTableAdapter.Connection.ConnectionString);

Hi all

I browsed this tip from FMS and noticed at the bottom a way to view deleted rows of a DataSet should you wish to:

  http://www.fmsinc.com/free/NewTips/NET/NETtip56.asp 

'in order to access the values from the deleted row you can create a filtered dataview

  Debug.WriteLine("Retrieve the values of deleted rows")

  Dim dv As New DataView(dt, "", "", DataViewRowState.Deleted)

  For Each drv As DataRowView In dv
    Debug.WriteLine("ID: " & drv.Item("ID").ToString & _
    ", Name: " & drv.Item("Name").ToString)

You can also read the data from a deleted DataRow on a field by field
basis, but it's a little different:


If myRow.RowState = DataRowState.Deleted Then
	strVal = myRow.Item("Field1", DataRowVersion.Original).ToString
Else
	strVal = myRow.Field1
End If


We use this when we need to do something like renumber a sequence value
in an array of DataRows where one or more has been deleted.

Hi John

I had a look but unfortunately it seems as your demo form only deals with the settings for the form.

What I am after is an option to - from code - not only read but also write the application settings as shown on tab Settings when you open the project's Properties from menu Project (bottom entry).
These can be read easily but only written to if you attack the underlying XML file which I don't like - I mean, if the settings are read-only it is for a reason, though dull.

So I wondered what others do to persistently save various application settings?

Setting Values at Run Time

Some applications are built with administration tools that can update the
application's settings.  In ASP.NET 2.0, we can modify settings in the
web.config in our code.  This is something we would want to do in response
to a button's click event.  The sample code below shows how easy it is to
modify an application setting in ASP.NET 2.0.

Dim cfg As Configuration
cfg = WebConfigurationManager.OpenWebConfiguration("~")
 
Dim setting As KeyValueConfigurationElement = _

Are you talking about settings for Visual Studio or settings for an
application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi Charlotte

It is the app.config xml file for application settings like Connection strings and so on:

  C:\...\Visual Studio 2005\Projects\<project>\<project>\app.config

It holds the entries from the menu Project, <project> Properties pane, tab Settings.

Nothing wrong with XML files. It's just that it seems that this file is for VS's use, so don't tamper with it.

If you reference System.Configuration you can easily read from it via code, and methods exists for editing and saving values for _users_, however nothing can be saved for the _application_:

Are you talking about settings for Visual Studio or settings for an
application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi all

How do you store application settings?

I've noticed the nice pane with the tab "Settings" for manually doing
this, but it is read-only from code.
Of course you can step down and attack the xml file storing the data,
but I find that a bit clumsy.

OK, you've totally lost me.  We don't reference either of those files,
and why should we?  All (or virtually all) of the contents are created
as we build the application.  The only time we modify our app.config is
to handle a DataDynamics licensing issue on our onw workstations.  Geeks
notwithstanding, settings only apply at runtime, and we can control
those nicely with xml files.  We store our connection strings in an xml
file, not in app.config, and read them when we need them.  Obviously,
userIDs and passwords are NOT stored in the xml file.

I still have the feeling we're talking about two different things here.

Message-ID: <s7c81534.029@cactus.dk>

Hi Charlotte et al

OK, I'm a child of VS2005, and when creating data sources the wizard kindly asks if you wish to save the connection strings in a file. Yes please, and that file happens to be app.config which you can read and write via the GUI.

Now I realize that this file has entries for application settings as well as user settings where the main difference is that the application settings are read-only during runtime. This, of course, limits the value of using the application settings as you may have a need to store or edit application setting entries during runtime.
I don't like to reinvent the wheel so I wondered if any method exists to circumvent this limitation other than to create a separate system as you have done. The only method I have seen is to open the app.config XML file directly as any other XML file:

  http://www.ryanfarley.com/blog/archive/2004/07/13/879.aspx 

To complicate matters, an advice is _not_ to do that because - as I mentioned previously - if the app.config file is read-only, it might be for a reason. That reason is explained here:

  http://www.interact-sw.co.uk/iangblog/2004/11/25/savingconfig 

where the author claims that one should never write files into the Program Files folder ..(!) .. but use the Application Data folder of the user.
That may be true, and I sure want to behave, but the next question is then: Where to store config files and such common for all users? Would that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

Storing stuff in the registry is definitely discouraged in dotNet,
Susan.  And more and more, the registry is being locked down by system
administrator.  We started to run into problems with that in our extant
Access applications.

Do you mean have the user physically browse through the rows looking for specific records?

If that is the case, I would probably go with a DatagridView bound to the source data.
When the user selects a row (double click, highlight and click a button or whatever), read the 
row data and feed it to a TableAdapter.Insert on the target table.

Hi Stuart et al

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

I think you need to follow with kunderT.Update to update the underlying database from the 
TableAdapter.

Hi Col and Denice,

The final version of the time detail report is in place.
I had to use the 'unscheduled' attribute to identify the OT.  So any
unscheduled OT will show in the ADJ/ENT column only.

Let me know if there are any problems.

FYI
We are moving offices tomorrow and we cant be sure when Telstra will
have the new phone lines ready
or when our internet connection will be available.  It is probably a
good idea to catch me on the mobile till
it gets sorted out.

regards

Hi Stuart

That is what I imagined initially.
Problem is, however and to my surprise, that neither a DataSet nor a DataTable features an Update method.

So what to do? 
I can't believe you have to revert to pure SQL commands to write back an update of a DataSet or DataTable??

Message-ID: <s7a9c475.014@cactus.dk>

Hi Stuart et al

Oh my, make a note on this should you ever wish to copy data between DataSets or DataTables with method ImportRow.

The secret is the value of property RowState of the individual rows. Rows read from a table have a RowState of Unchanged.
If a row is copied to another DataSet/DataTable by method ImportRow, RowState remains Unchanged.

In my code sample below, I marked rows as Modified with method SetModified.

The Update method of the DataTableAdapter, which is called to write the data rows to the underlying table, is quite clever as it doesn't touch rows with RowState Unchanged.
However, rows with RowState Modified will only be used to update existing records in the target table, thus it will not attempt to append or insert any such row. 

For a row to be inserted by the later Update call, it has to have RowState set to Added.

So, for my code below, I have to decide if a row should update an existing record, or if it should be appended, or if it should be ignored - and then call the method SetModified or SetAdded or nothing:

                    // Mark row as modified.
                    kundeRowS.SetModified();
or:
                    // Mark row as new.
                    kundeRowS.SetAdded();

When I changed the code from SetModified to SetAdded and replaced the Fill method with:

      kundeAdapterT.Update(kunderT);

all records were written to the target table.

Of course, if you can write your code to add rows not using method ImportRow - with LoadDataRow or like:

                    kunderT.Rows.Add(rowToAdd);

RowState of those rows, I guess, will be switched to Added automatically.

No there is no GUI, just code.
I have some code like this. It add rows but will not save them to the database table:

                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                kunderS = kundeAdapterS.GetDataVrsKunder();
                kunderT = kundeAdapterT.GetDataVrsKunder();

                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    Console.WriteLine("Kunde: " + kundeRowS.navn + "");
                    Console.WriteLine("  Kundenr: " + kundeRowS.kundeNr + "");
                    // Mark row as modified.
                    kundeRowS.SetModified();
                    kunderT.ImportRow(kundeRowS);
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                kundeAdapterT.FillVrsKunder(kunderT);

Target table is residing in MSDE. 
Count of s returns the count of records to add. 
Count of t returns existing records + count of records to add.

What am I missing?

Glad it's not just me trying to get my head around .Net and data at the moment. :-)
After 15 years of Access and classic VB development, there's so much new stuff to learn

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7aafb33.042@cactus.dk>

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after having browsed thousands of sites (so it feels). I thought it would be a simple job to locate code somewhere around that I could modify, but no. Well, yes, but that is basic code snippets working with connection strings and SQL commands and so on for ASP kiddies. This must be very special, though I thought it to be some kind of standard routine. But no.

So again, should you ever have a task like the subject to do, make a note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL Update command which raised the error when you finally call the Update method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_with_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a row of another type (remember, source and target are from different DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter kundeAdapterS =
                    new VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter kundeAdapterT =
                    new VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();
                // DataTable for target.
                kunderT = kundeAdapterT.GetDataVrsKunder();

                // Read each row from the source rows.
                // Update those found in the target table.
                // Append those not found in the target table.

                // Variable to hold primary key to locate.
                Int32 key;
                // Create row to hold a found row in the target.
                VrsTarget.DataTableKundeRow foundRow = null;
                foreach (VrsSource.DataTableKundeRow kundeRowS in kunderS)
                {
                    // Value of primary key to locate.
                    key = kundeRowS.kundeNr;
                    // Find a matching row in the target.
                    foundRow = kunderT.FindByKundeNr(key);
                    
                    if (foundRow == null)
                    {
                        // Row is not found. 
                        // Set the RowState of the source row as Added.
                        kundeRowS.SetAdded();
                        // Append it to the target preserving the RowState.
                        kunderT.ImportRow(kundeRowS);
                    }
                    else
                    {
                        // Row is found.
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = kundeRowS.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
 
                Console.WriteLine("s: " + kunderS.Count.ToString());
                Console.WriteLine("t: " + kunderT.Count.ToString());

                // Write back to the database table the updated target DataTable.
                kundeAdapterT.Update(kunderT);
                // Call AcceptChanges if needed for further processing.
                // kunderT.AcceptChanges();

Still, if anyone have a better method, I'm all ears. This is by no means an expert area for me.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically
for that.  A datatable has a Copy method, and that would be the logical
way to copy a table, if that's all you were doing.

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

            da.Update(dsTmp.Tables(0))
        Next

        dsTmp.Dispose()
    End Sub

Hi Charlotte and Stuart

That's a good idea - if the code works. I have not much hair left after
having browsed thousands of sites (so it feels). I thought it would be a
simple job to locate code somewhere around that I could modify, but no.
Well, yes, but that is basic code snippets working with connection
strings and SQL commands and so on for ASP kiddies. This must be very
special, though I thought it to be some kind of standard routine. But
no.

So again, should you ever have a task like the subject to do, make a
note of this method.

Main issue is that the DataTableAdapter wizard creates a buggy SQL
Update command which raised the error when you finally call the Update
method of the DataTableAdapter:

  "Concurrency violation: the UpdateCommand affected 0 of the expected 1
records."

The key to solve this I found here:

http://geekswithblogs.net/gaijin42/archive/2007/09/05/update_dataset_wit
h_new_rows_acceptchanges_setmodified_orm_business_objects.aspx 

During testing I received first the "Concurrency violation" message and
only a Select statement was found for the Update SQL command. 
Later - somehow - the wizard generated the full Update SQL command with
a bunch of parameters - and that failed too.
Then I edited the Update SQL as described by Jason to include the
parameter for the primary key only. That worked!

Finally, I found that the simplest method to copy a row of one type to a
row of another type (remember, source and target are from different
DataTableAdapters) is to copy the ItemArray.

So now I can update and append to the target rows from the source rows
in one go with this code:

                // DataTableAdapter to copy from.
                VrsSourceTableAdapters.DataTableKundeTableAdapter
kundeAdapterS =
                    new
VrsSourceTableAdapters.DataTableKundeTableAdapter();
                VrsSource.DataTableKundeDataTable kunderS;

                // DataTableAdapter to copy to.
                VrsTargetTableAdapters.DataTableKundeTableAdapter
kundeAdapterT =
                    new
VrsTargetTableAdapters.DataTableKundeTableAdapter();
                VrsTarget.DataTableKundeDataTable kunderT;

                // DataTable for source.
                kunderS = kundeAdapterS.GetDataVrsKunder();

Still, if anyone have a better method, I'm all ears. This is by no means
an expert area for me.

I've fallen over that one before too, and the best way to avoid that is
to put the code in a public helper class and then call it when you need
to do that task.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you copy a row by clearing the target first and then importing the source/remote row? But what does method Clear do here? As far as I know, Clear "erases" the row and leave it - it does not delete it.

The thing is, you aren't just copying a table.  It sounds like you're
only making a copy if one doesn't exist.  Otherwise, you're making sure
the records are in sync.  That's a bit more complicated than just
copying a table, so I can see why you didn't find any code specifically

Here's an example of an approach we use when importing a table.  The
ImportAdaptor method it calls simply returns an instantiated
OleDb.OleDbDataAdapter that has already retrieved a pre-build
dataadapter for handing that table.  Maybe it will give you some ideas:

    Public Sub ImportTable(ByVal table As System.Data.DataTable)
Implements IMiscData.ImportTable
        Dim da As OleDb.OleDbDataAdapter =
ImportAdapter(table.TableName)
        Dim dsTmp As DataSet = table.DataSet.Clone

        For Each rowRemote As DataRow In table.Rows
            dsTmp.Tables(0).Rows.Clear()
            dsTmp.Tables(0).ImportRow(rowRemote)

            dsTmp.Tables(0).Rows(0).AcceptChanges()
            dsTmp.Tables(0).Rows(0).SetModified()

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call the Update method of the DataTableAdapter which causes a roundtrip to the database server. 
I was looking for a method to update the complete DateTable (or DataSet) and then save the complete collection of updated/appended rows in on go. 

However, right now my code saves the complete DataTable as all existing rows are updated. I'm looking for method to check if a row actually is changed or not. As the target and source rows come from two different DataTableAdapters I cannot use Equal. It seems I have to compare the content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the fields - to compare two arrays.
Any suggestions?

I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

My last reply wasn't too enlightening.  What's going on here is we are
importing using a dataadapter to a table of the same name.  In other
words, we're updating an existing table and adding any new rows.  The
data may be from a file, a table, a dataset, or whatever, but by the
time it gets to this routine, it's in a datatable.  Normally, we're
importing from XML.

We create a copy of the table passed in using the Clone method so we
have the structure automatically.  For each datarow in the table passed
in,  we clear the clone's datarow collection and import the row into the
clone.  We then acceptchanges to get the row solidly into the clone
table and the SetModified to mark it as changed.  Then we pass that
clone with its single modified row to the update method of the
dataadapter, which takes care of shoving it into the existing table
we're updating.

Hi Charlotte

Thanks. Yes, my task is obviously slightly more complicated ... and, of
course, in most situations you operate on one database only.

I can see that you use the ImportRow method too. And as I read it, you
copy a row by clearing the target first and then importing the
source/remote row? But what does method Clear do here? As far as I know,
Clear "erases" the row and leave it - it does not delete it.

Message-ID: <s7ac19c1.068@cactus.dk>

Hi Charlotte

Thanks for that explanation, I can see why you do it this way.

My situation is somewhat different as no data will be live - the source is an Access mdb permanently linked to the SQL Server - and the import will be run at regular intervals. Thus, should a row or two be lost during an import they will be fetched at the next run.

As for the array compare, I will check out your idea of a temp table.

/gustav

>>> cfoust at infostatsystems.com 08-02-2008 02:16 >>>
I think the speed depends on how you use it and whether your BE is
Access or SQL Server. Doing it this way handles those pesky concurrency
issues. Plus, we don't know whether the row is going to be updated or
inserted when we try the update call.  

The ImportAdapter we call in the routine adds a handler for the
RowUpdated event of the DataAdapter.  When the event fires, we trap any
OleDbException and decide what to do about it.  If an update call
failed, we try creating a dataset clone and attempting to LoadDataRow
using an ItemArray of the items in the row.  If that works, we call the
ImportAdapter to update the row from the clone dataset and we set the
row's UpdateStatus to SkipCurrentRow.  If we tried an insert and it
failed with a duplicatevalue exception, we know the row exists, so we
acceptchanges on it, setModifed and then call the ImportAdapter to
update the row then we set the row's UpdateStatus to SkipCurrentRow.

And if you're updating live data, you don't have much choice because
someone else could change it between the time you accepted a changed row
and the time it was actually written back to the DB.

I don't know of a way to directly compare ItemArrays, but that doesn't
mean one doesn't exist.  I can see why you can't cast them as strings
though, since they can hold any kind of object.  What about importing
one ItemArray into a temp datatable and then trying to update it with
the other one?  If the update succeeds, they don't match.

Hi Charlotte

OK, now I see. Sounds pretty as the exact same task I have to carry out.

But isn't that terrible slow? I mean, for each row to import you call
the Update method of the DataTableAdapter which causes a roundtrip to
the database server. 
I was looking for a method to update the complete DateTable (or DataSet)
and then save the complete collection of updated/appended rows in on go.


However, right now my code saves the complete DataTable as all existing
rows are updated. I'm looking for method to check if a row actually is
changed or not. As the target and source rows come from two different
DataTableAdapters I cannot use Equal. It seems I have to compare the
content of the rows to look for a match.

This doesn't seem to work:

   targetRow.ItemArray == sourceRow.ItemArray

but perhaps this will:

   targetRow.ItemArray.ToString() == sourceRow.ItemArray.ToString()

Anyway, I'm looking for a general ans simple way - without looping the
fields - to compare two arrays.

Subject: [dba-VB] Copy tables: Update or insert rows in
	a	DataTableAdapter from another DataTableAdapter
Message-ID: <s7ac946f.095@cactus.dk>

Hi Charlotte and Stuart et al

The hash code of a row cannot be used as it is based on the parent (name of DateTable or DataSet object) and the position of the row in this, not the content. And ToString of the ItemArray and other objects just returns the name of the object, not the content or value of it.

However, I located a very simple method to compare two arrays with "normal" content - not BLOBS or binaries - without having to code loops and so on.

Once again, the .Net framework came to rescue - this time with Concat which (also) is able to concatenate the rows of an array.
So:

            // DataTableAdapter to copy from.
            VrsSourceTableAdapters.DataTableOrdreTableAdapter ordreSAdapter =
                new VrsSourceTableAdapters.DataTableOrdreTableAdapter();
            VrsSource.DataTableOrdreDataTable ordreS;

            // DataTableAdapter to copy to.
            VrsTargetTableAdapters.DataTableOrdreTableAdapter ordreTAdapter =
                new VrsTargetTableAdapters.DataTableOrdreTableAdapter();
            VrsTarget.DataTableOrdreDataTable ordreT;

            // DataTable for source.
            ordreS = ordreSAdapter.GetDataVrsOrdrer();
            // DataTable for target.
            ordreT = ordreTAdapter.GetDataVrsOrdrer();

            // Read each row from the source rows.
            // Update those found in the target table.
            // Append those not found in the target table.

           // Variable to hold primary key to locate.
            Int32 key;
            // Create row to hold a found row in the target.
            VrsTarget.DataTableOrdreRow foundRow = null;
            // Variables to hold hash codes of row contents.
            int hashSource;
            int hashTarget;
            
            foreach (VrsSource.DataTableOrdreRow ordreSRow in ordreS)
            {
                // Value of primary key to locate.
                key = ordreSRow.ordreNr;
                // Find a matching row in the target.
                foundRow = ordreT.FindByOrdreNr(key);

                if (foundRow == null)
                {
                    // Row is not found. 
                    // Set the RowState of the source row as Added.
                    ordreSRow.SetAdded();
                    // Append it to the target preserving the RowState.
                    ordreT.ImportRow(ordreSRow);
                }
                else
                {
                    // Row is found.
                    Console.WriteLine("  Found: " + key.ToString());
                    // Calculate hash code to see if source row and target row match.
                    hashSource = String.Concat(ordreSRow.ItemArray).GetHashCode();
                    hashTarget = String.Concat(foundRow.ItemArray).GetHashCode();
                    Console.WriteLine(" - Hash: " + hashSource.ToString() + " - " + hashTarget.ToString());
                    if (hashSource != hashTarget)
                    {
                        // The source row is updated.
                        Console.WriteLine("  Modified OrdreNr: " + ordreSRow.ordreNr + "");
                        // Copy full content from source row to target row.
                        // This sets RowState of the target row to Modified.
                        foundRow.ItemArray = ordreSRow.ItemArray;
                        // Do NOT call AcceptChanges here as this would clear property RowState.
                    }
                }
            }

            // Write back to the database table the updated/appended rows of target DataTable.
            ordreTAdapter.Update(ordreT);


Of course, if you have juxtaposed columns with similar content like:

  Val1  Val2  Concatenated string
   3      44     344
  34      4      344

just concatenating these may in some cases fail as the right column shows, but that is not the case for my current task.

So now I only update modified records and append new records leaving the bunch of not modified records untouched!

Hello John,

Excel.Worksheet object has several events related to Excel.Range:

Event Change(Target As Range)
Event SelectionChange(Target As Range)
Event BeforeDoubleClick(Target As Range, Cancel As Boolean)
Event BeforeRightClick(Target As Range, Cancel As Boolean)

You can try to explore and use these events...

Excel.Workbook object has a couple of useful events to implement validation
on whole worksheet/workbook level:

Event BeforeSave(SaveAsUI As Boolean, Cancel As Boolean)
Event BeforeClose(Cancel As Boolean)

Shamil,


I may be asking you a few questions over the next few days as I'm working on
a new project so if they are basic questions, bare with me.

I was successful in using the BeforeDoubleClick event on a 'sheet', but want
it to work for 'every sheet' without having to add the code to every sheet.

I tried the following at the 'workbook' level for testing and hoped it would
be global across all sheets. Am I thinking about this in the wrong way?

Here is the code:

Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target
As Range, Cancel As Boolean)
  MsgBox "The Target Is " & Target
  MsgBox "The Target Name Is " & Target.AddressLocal
End Sub

It was actually working at the workbook level. I hadn't closed the first

It was actually working at the workbook level. I hadn't closed the first
message box while I was trying the other sheets and the message box went to
the background (I've never seen this before and can't reproduce it) Doesn't
really matter. It's working, thanks.

Shamil,


I may be asking you a few questions over the next few days as I'm working on
a new project so if they are basic questions, bare with me.

I was successful in using the BeforeDoubleClick event on a 'sheet', but want
it to work for 'every sheet' without having to add the code to every sheet.

I tried the following at the 'workbook' level for testing and hoped it would
be global across all sheets. Am I thinking about this in the wrong way?

Here is the code:

Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target
As Range, Cancel As Boolean)
  MsgBox "The Target Is " & Target
  MsgBox "The Target Name Is " & Target.AddressLocal
End Sub

Hi al

How odd is this? I just took the time to install SQL Server 2008 Express CTP and VS2008 on a new machine (Vista) to enjoy a brave new world.
But as soon you attempt to connect to the server, this message pops:

"This server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported." 

They must be kidding ... even an add-on for VS2005 is available:

http://www.microsoft.com/downloads/details.aspx?FamilyID=e1109aef-1aa2-408d-aa0f-9df094f993bf&displaylang=en

How odd is this? VS2008 ships with the SQL Server 2005 Express but still.
Any ideas on how to get it to accept SQL Server 2008 CTP?

Hi all

Found this tip which can save you a lot of time and lost hair:

  http://codingreflection.com/wordpress/?p=371

should you receive the message:

  "None of the selected features can be installed or upgraded."

If so, use this command to run the install where d is your cd drive:

Subject: [dba-VB] Visual Studio 2008: MSDTC on server 'servername'
	is	unavailable (Solution)
Message-ID: <s7af3efa.008@cactus.dk>

Hi all

When you try to connect to a linked database on a remote server, you will probably succeed.
However, when you try to preview the data (using the GetData.. method), you may receive this message just as data are to be retrieved:

  MSDTC on server 'servername' is unavailable

I found the solution here:

  http://geekswithblogs.net/narent/archive/2006/10/09/93544.aspx 

<quote>
Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Run MS DTC

If you have the application and the SQL Server Data base in two different machines you must do that also

Control Panel > Adminstrative Tools > Component Services > Computers > 
(right click) My Computer > Properties > MS DTC (TAB) > allow remote access 
</quote>

In my case, the MS DTC service was running - I just had to touch it as described to get it working.
Somewhat strange, I think, but who cares.

Also, I modified the hosts and lmhosts.sam files to include the name lookup of the remote server as this is not a server with a public URL, but I'm not sure if that really is necessary as VS previously was perfectly able to preview a table of a normal database (but not of a linked) on that same server.

hosts file:
xxx.xxx.xxx.xxx	servername		# Description of server

lmhosts.sam file:
xxx.xxx.xxx.xxx	servername	#PRE	#Description of server

True, but indeed I suspect this issue to be true also if the SQL Server 2008 is installed on a remote machine.

VS2008 seems to have very few issues running on Vista Business which is what I use.

Subject: [dba-VB] How to set password for a DataTable(Adapter)'s connection?
Message-ID: <s7bc9003.006@cactus.dk>

Hi all

Is it possible at runtime to set the password for the connection when you open a DataTableAdapter?

I have code like this:

            // DataTableAdapter to copy from.
            RemoteTableAdapters.CompanyTableAdapter sourceDataTableAdapter =
                new RemoteTableAdapters.CompanyTableAdapter();
            Remote.CompanyDataTable sourceDataTable;

            // DataTableAdapter to copy to.
            LocalTableAdapters.CompanyTableAdapter targetDataTableAdapter =
                new LocalTableAdapters.CompanyTableAdapter();
            Local.CompanyDataTable targetDataTable;

            // DataTable for source.
            sourceDataTable = sourceDataTableAdapter.GetData();
            // DataTable for target.
            targetDataTable = targetDataTableAdapter.GetData();

If the underlying database connection needs a password, the code fails at the line with GetData().

Would I need to go all the way back to read the ConnectionString, modify this, and reapply? How?
Or is there a more clever method? At best like:

          targetDataTableAdapter.Connection.SetPassword("secret");

I browsed this tip from FMS and noticed at the bottom a way to view deleted rows of a DataSet should you wish to:

  http://www.fmsinc.com/free/NewTips/NET/NETtip56.asp 

'in order to access the values from the deleted row you can create a filtered dataview

  Debug.WriteLine("Retrieve the values of deleted rows")

  Dim dv As New DataView(dt, "", "", DataViewRowState.Deleted)

  For Each drv As DataRowView In dv
    Debug.WriteLine("ID: " & drv.Item("ID").ToString & _
    ", Name: " & drv.Item("Name").ToString)
  Next

You can also read the data from a deleted DataRow on a field by field
basis, but it's a little different:


If myRow.RowState = DataRowState.Deleted Then
	strVal = myRow.Item("Field1", DataRowVersion.Original).ToString
Else
	strVal = myRow.Field1
End If


We use this when we need to do something like renumber a sequence value
in an array of DataRows where one or more has been deleted.

Subject: [dba-VB] DataSet, view deleted rows

Hi all

I browsed this tip from FMS and noticed at the bottom a way to view
deleted rows of a DataSet should you wish to:

  http://www.fmsinc.com/free/NewTips/NET/NETtip56.asp 

'in order to access the values from the deleted row you can create a
filtered dataview

  Debug.WriteLine("Retrieve the values of deleted rows")

  Dim dv As New DataView(dt, "", "", DataViewRowState.Deleted)

  For Each drv As DataRowView In dv
    Debug.WriteLine("ID: " & drv.Item("ID").ToString & _
    ", Name: " & drv.Item("Name").ToString)
  Next

/gustav

Hi Charlotte

That is of course more direct for single values.
So much to learn ...

/gustav

You can also read the data from a deleted DataRow on a field by field
basis, but it's a little different:


If myRow.RowState = DataRowState.Deleted Then
	strVal = myRow.Item("Field1", DataRowVersion.Original).ToString
Else
	strVal = myRow.Field1
End If


We use this when we need to do something like renumber a sequence value
in an array of DataRows where one or more has been deleted.

Hi all

How do you store application settings?

I've noticed the nice pane with the tab "Settings" for manually doing this, but it is read-only from code.
Of course you can step down and attack the xml file storing the data, but I find that a bit clumsy.

Hi John

I had a look but unfortunately it seems as your demo form only deals with the settings for the form.

What I am after is an option to - from code - not only read but also write the application settings as shown on tab Settings when you open the project's Properties from menu Project (bottom entry).
These can be read easily but only written to if you attack the underlying XML file which I don't like - I mean, if the settings are read-only it is for a reason, though dull.

So I wondered what others do to persistently save various application settings?

Setting Values at Run Time

Some applications are built with administration tools that can update the
application's settings.  In ASP.NET 2.0, we can modify settings in the
web.config in our code.  This is something we would want to do in response
to a button's click event.  The sample code below shows how easy it is to
modify an application setting in ASP.NET 2.0.

Listing 8

Protected Sub btnUpdateSetting_Click(ByVal sender AsObject, ByVal e As
System.EventArgs) _
 Handles btnUpdateSetting.Click
 
Dim cfg As Configuration
cfg = WebConfigurationManager.OpenWebConfiguration("~")
 
Dim setting As KeyValueConfigurationElement = _
CType(cfg.AppSettings.Settings("MySetting"),KeyValueConfigurationElement)
 
If Not setting Is Nothing Then
  setting.Value = "New Value Setting"
  cfg.Save()
End If
End Sub

application?  We use XML files for storing application settings (not VS
settings), Gustav.  I don't know why you characterize it as clumsy, and
we don't "attack" any xml files.

Hi Charlotte

It is the app.config xml file for application settings like Connection strings and so on:

  C:\...\Visual Studio 2005\Projects\<project>\<project>\app.config

It holds the entries from the menu Project, <project> Properties pane, tab Settings.

Nothing wrong with XML files. It's just that it seems that this file is for VS's use, so don't tamper with it.

If you reference System.Configuration you can easily read from it via code, and methods exists for editing and saving values for _users_, however nothing can be saved for the _application_:

OK, you've totally lost me.  We don't reference either of those files,
and why should we?  All (or virtually all) of the contents are created
as we build the application.  The only time we modify our app.config is
to handle a DataDynamics licensing issue on our onw workstations.  Geeks
notwithstanding, settings only apply at runtime, and we can control
those nicely with xml files.  We store our connection strings in an xml
file, not in app.config, and read them when we need them.  Obviously,
userIDs and passwords are NOT stored in the xml file.

I still have the feeling we're talking about two different things here.

Message-ID: <s7c81534.029@cactus.dk>

Hi Charlotte et al

OK, I'm a child of VS2005, and when creating data sources the wizard kindly asks if you wish to save the connection strings in a file. Yes please, and that file happens to be app.config which you can read and write via the GUI.

Now I realize that this file has entries for application settings as well as user settings where the main difference is that the application settings are read-only during runtime. This, of course, limits the value of using the application settings as you may have a need to store or edit application setting entries during runtime.
I don't like to reinvent the wheel so I wondered if any method exists to circumvent this limitation other than to create a separate system as you have done. The only method I have seen is to open the app.config XML file directly as any other XML file:

  http://www.ryanfarley.com/blog/archive/2004/07/13/879.aspx 

To complicate matters, an advice is _not_ to do that because - as I mentioned previously - if the app.config file is read-only, it might be for a reason. That reason is explained here:

  http://www.interact-sw.co.uk/iangblog/2004/11/25/savingconfig 

where the author claims that one should never write files into the Program Files folder ..(!) .. but use the Application Data folder of the user.
That may be true, and I sure want to behave, but the next question is then: Where to store config files and such common for all users? Would that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

where the author claims that one should never write files into the
Program Files folder ..(!) .. but use the Application Data folder of the
user.
That may be true, and I sure want to behave, but the next question is
then: Where to store config files and such common for all users? Would
that be:

  C:\Documents and Settings\All Users\Application Data\YourApp

So, where do you store your application data common for all users?

=====I'm not sure if VS works the same way as Access, but in Access, I store 
individual settings in the registry.

Storing stuff in the registry is definitely discouraged in dotNet,
Susan.  And more and more, the registry is being locked down by system
administrator.  We started to run into problems with that in our extant
Access applications.

Hi Charlotte

Thanks. I'll stick to that method.

I don't know if it's THE answer, but it's the one we use.

Hi all

Again, pressing Send helps assimilation. 
Just browsed to the last paragraph of the link. Calling:

 
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationDat
a)

returns on my machine:

  "C:\\Documents and Settings\\All Users\\Application Data"

Is that the answer?

Too bad... it's an easy solution.
