[AccessD] ADO Connection from FORM

You can create a compiled ADE from an ADP, and yes, you can create distributable ADP applications.

Hi Jaun:

Only an ADP Access form can connection directly to recordset otherwise an ODBC connection string can but that is one layer up from ADO-OLE and performance tend much reduce especially if you have just requested a large group of records. I tend to dynamically link and lock the recordset, instead of the forms and use code to feed the forms. I am sure there is other methods. I posted the following code a week ago but you might not have seen
it:

code >>>

Public mobjConn As ADODB.Connection
Public gstrConnection As String

On Error GoTo Err_NotConnected

' if your are connecting to MDB database
gstrConnection = "Provider=Microsoft.Jet.OLEDB.4.0; _
               Persist Security Info=False; _
               Data Source= MyDatabaseNameAndLocation"

' Test connection string
Set mobjConn = New ADODB.Connection
mobjConn.ConnectionString = gstrConnection
mobjConn.Open
MsgBox "You are connected "

Exit_GetConnected:
 Exit Sub

Err_NotConnected:
 MsgBox "You are not connected "
 Resume Exit_GetConnected
..........

and everytime you want to connect after that...

 Dim cmdInvoice As ADODB.Command
 Public rsInvoice As ADODB.Recordset

 Set rsInvoice = New ADODB.Recordset
 Set cmdInvoice = New ADODB.Command

' accessing a parameterized query in a MDB database
With cmdInvoice
 .ActiveConnection = gstrConnection
 .CommandText = "MyQuery"
 .CommandType = adCmdStoredProc
 .Parameters.Append .CreateParameter("InvoiceCode", adChar, adParamInput, 10, strInvoiceCode) End With

With rsInvoice
 .CursorLocation = adUseClient
 .LockType = adLockBatchOptimistic
 .Open cmdInvoice
 If .EOF = False And .BOF = False Then
  .MoveLast
  GotInvoice = True
 End If
End With

...or direct, no command section needed

With rsInvoice
 .CursorLocation = adUseClient
 .LockType = adLockBatchOptimistic
 .Open "SELECT * FROM Invoice " & _
             "ORDER BY [Group]", gstrConnection
 If .EOF = False And .BOF = False Then
  .MoveLast
  GotInvoice = True
 End If
End With

<<< code

HTH
Jim

We are trying to connect from a FORM to and external MYDATA.MDB on a server.

We are sure that ADODB could be use but we only use ASP forms to make this and put over the server. On the ASP page is very simple to connect : <CODE> Set Ob_Conn=Server.CreateObject("adodb.connection")
Set Ob_RS=Server.CreateObject("adodb.recordset")
Ob_Conn.Open "Driver={Microsoft Access Driver (*.mdb)}; " & "Dbq=" &
Server.MapPath("datos.mdb")
Sql= "SELECT *  FROM productos where familiaid='"&cadena&"'  order by codigo" Ob_RS.open  Sql,Ob_Conn,adOpenStatic, adCmdTable Ob_RS.PageSize = 6
Ob_RS.AbsolutePage=Session("pagina")
</CODE>

But to make the same on a simple FORM like a RecordSource?? Or in VB into de form to collect some data to visualize ??

Thanks
