That sounds perfect Dan! How do you pass the information from the .ini file
into the database?

Hi Roz,
I had a similar server switching event at an early customer where it took me
5 hours to recode one database. Vowing to never go through that again, I
eventually learned how to put the server path in one .ini file. Now the
database reads the path from the .ini file on opening. A .ini file is simply
a text file with a .ini extension, structured in a specific way.
For my convenience, I put the .ini file into the same folder as the front end
.mdb. You could use one file for all your databases.
You might be able to create one small database just for this purpose that
could then be called by all the other databases??? I haven't tried this
myself.
Last month at a different customer when we switched servers, changing the
path to the new server was a complete non-event. I just typed in the new
path in the .ini file - done in 20 seconds.
Note: frmGlobalVariables is a hidden sentinel form which contains many
global variables and is always open.
Note: SystemFolderPath and SystemBEName are functions which read from the
sentinel form.
Example .ini file contents:
-----------------------------------------------------------------------
[Parameters]
SystemFolderPath=\\10.99.99.99\prod$\Operations\PSISystem
SystemBEName=PSIBE.mdb
-----------------------------------------------------------------------
Example Code:
'----------------------------------------------------------------------
Public Sub PopulateBEPath()
On Error GoTo EH
Dim frm As Form
Set frm = Forms("frmGlobalVariables")
frm("txtINIFileName") = "PSI.ini"
frm("txtSystemFolderPath") = ReadIniFile("Parameters",
"SystemFolderPath")
frm("txtSystemBEName") = ReadIniFile("Parameters", "SystemBEName")
frm("txtBEFullPath") = SystemFolderPath & "\BackEnd\" & SystemBEName
Exit Sub
EH:
Call GlobalErrors("", Err.Number, Err.Description, "Startup",
"PopulateBEPath", , , "Line " & Erl)
End Sub
HTH,
Dan

Subject: [AccessD] Drive mappings & global constants
Dear List
I have just been asked to resolve something, in zero time as usual, and I'm
sure there should be an elegant solution I just can't think of it.
There is a team that has 100+ Access databases, Excel spreadsheets and Word
templates that contain dependencies on a particular network drive that is
currently mapped to 'h:\'. In a few weeks time they will no longer be able to
use 'h:\' and will be given a new drive mapping. At some point shortly after
that, the server will be changed too, so the current DNS path will no longer
be valid either.
I don't know -and nobody will say for definite - what the new mapping & new
DNS path will be. These files are critical and the business insists on no
more than 24 hours downtime.
The dependencies include import/export routines, linked tables & linked
files.
What I would like to do is run a giant F&R on the code modules and replace
the root drives with a constant, and then make the constant available so that
ALL the applications use the constant. Then they can muck about with drive
mappings etc. to their heart's content and I won't have to come back to the
South coast and stay up all night changing code.
Any tips or ideas for making this work? Is it possible? I have code for
updating the code modules that should almost work but I've no idea how to
expose a constant across multiple apps.
TIA
Roz
