I have an Access 2007 Split DB (front & backend). I am distributing the front end to different users in different sites. The issue is re-linking the tables. How do I program when the front end is opened by the user that it checks and re-links their backend tables for them?

There are plenty of free utilities available to do this.  Check out the downloads for Relinker samples here:

This blog post explains how to relink at startup... similar code to what you'll find in those samples:

place this code in a regular module

Sub RelinkTables()
On Error GoTo Relink_Error
Dim dbs As DAO.Database, strBEPath As String
Dim tdf As DAO.TableDef
Set dbs = CurrentDb()
strBEPath = "<complete path to your backend>"
Dim dbData  As DAO.Database
Set dbData = DBEngine.OpenDatabase(strBEPath)
     For Each tdf In dbs.TableDefs
          If tdf.Connect <> "" Then
               tdf.Connect = ";DATABASE=" & strBEPath
               tdf.RefreshLink
          End If
     Next
dbData.Close
Set dbData = Nothing

Relink_Error:
     If Err.Number = 3024 Then
          MsgBox "Unable to connect to data tables!" & vbCrLf & "Closing Application", vbQuestion, "DATA TABLES MISSING!"
          Err.Clear
           Application.Quit
     End If
End Sub


you can call the sub in the open or load event of your startup form.

Did you read/follow the detailed instructions at the link I posted in my last comment? (The code that cap1 posted is very similar).

mbizup: I just looked at the link you posted. The issue is that I will have the backend in a network folder and the front end will be on several users desktops.

one of the requirements for your code is that both files have to be in the same folder.

no error message, but it seemed to work after I had both files in the same network folder but thats not how I will them.

The backend will be on a network share and the front end will be on users desktops.

The idea there is to relink a single copy of the front end before distributing it to the users, rather than relinking separate copies on the users individual computers.

With that approach, you relink *once* and then distribute a properly linked FE to your users.

it will work where ever you place the FE. as long as you specify in the code the path to the BE


strBEPath = "<complete path to your backend>"


can  you post what did you place as the path to the BE

The issue is that I am distributing the FE to users on different networks, while maintaining the master FE for updates.

so you are calling the codes from a macro, then you need to change the "SUB" to "FUNCTION"


change this

Sub RelinkTables()

with

Function RelinkTables()

Ok, I got it working. There was an issue with module names and what I had in the autoexec.

When I open the FE from my desktop it connects to the path in the RelinkTables.

I think I will change it to buttons on the main screen for the different users. I will create seperate relinktables and buttons.

Thanks, for the help!

where did you place the "RelinkTables" codes  ?

I created the module "Function Name RelinkTables()"

With the code that you first gave me.

Then added the first line action "RunCode" with "RelinkTables()" for the arguments.
