Update linked tables in access using vba

I have a database with about 50 tables linked to a SQL Server catalog.  I have a catalog for each month using the following naming convention MTHYYYY.

To switch between catalogs I currently update my ODBC connection pointing to a new month then update all linked tables in my Access database using the "linked table manager" selecting "always prompt for new location".  The catalogs are secured usingSQL Server authenication and are the same for each catalog.

I would like to use VBA to update my linked tables and or point my ODBC connection to a new month allowing me to run queries across multiple months without have to change my ODBC connection and update all linked tables manually.  Also - it would be a bonus if other users / computers could connect to these tables w/o having to manually configure an ODBC connection.

Current Connection: DSN=Prime;APP=Microsoft Office 2003;WSID=SERVER;DATABASE=MTHYYYY;Network=ANON

I use this code to relink tables to a backend in the same folder as the current frontend database:

Function fncRelink()
'function to relink tables to the "_be" database
'It's assumed that the "_be" database is in the same folder as the frontend !

Dim td As DAO.TableDef

For Each td In CurrentDb.TableDefs
  If Len(td.Connect) > 0 Then
     td.Connect = ";DATABASE=" & Left(CurrentDb.Name, InStrRev(CurrentDb.Name, "\")) & Mid(td.Connect, InStrRev(td.Connect, "\") + 1)
     td.RefreshLink
  End If
Next

MsgBox "Ready, tables relinked"

End Function

But you can ofcourse change the path part.

I changed the DATABASE="XYZ part to the database/catalog I was trying to connect to and received the following error:

Connection failed:
SQLState: '08004'
SQL Server Error: 4060
Server rejected the connectioN; Access to selected database has been denied

A window then popped up allowing me to point to the correct server / database but errors out.

Hmm, does the build string look like the:
DSN=Prime;APP=Microsoft Office 2003;WSID=SERVER;DATABASE=MTHYYYY;Network=ANON
you need ?
Just use a breakpoint and ?td.Connect in the immediate window to findout the value before and after the assign statement.

I am sorry but I do not follow.  The database I am connecting to is not in the same folder as the frontend - it is a SQL Server.  Could this have something to do with my error?

The "working" td.Connect should be modified.
Thus my advise to check the present connection (e.g. in the queries properties popup form) and change the part that needs to be changed.
Can you show the string from a working linked table ? (Open the table in design mode and activate the properties)

This is it:

ODBC;DSN=Prime;APP=Microsoft Office 2003;WSID=ADMFIN;DATABASE=MTHYYYY;Network=ANON;TABLE=dbo._Codes

I would have expected:
ODBC;DSN=Prime;APP=Microsoft Office 2003;WSID=ADMFIN;DATABASE=062006;Network=ANON;TABLE=dbo._Codes
Thus needing an assign statement to create for the TABLE=dbo._Codes a connect string like:
td.Connect = "ODBC;DSN=Prime;APP=Microsoft Office 2003;WSID=ADMFIN;DATABASE=" & strMonthYear & ";Network=ANON;TABLE=dbo._Codes"

as you'll have multiple tables you can use a dynamic version like:
td.connect = "ODBC;DSN=Prime;APP=Microsoft Office 2003;WSID=ADMFIN;DATABASE=" & strMonthYear & ";Network=ANON;TABLE=" & right(td.connect,instrrev(td.connect,"=")+1)

This will add the MonthYear and place the table at the end.
