Oh and the fix is currently scheduled for early 2012 at this stage....  So nearly a year after the problem first appeared....

If you can do late binding it usually works, but that is not always a viable solution and there are performance issues associated with late binding as well. Of course it all depends on how much code you have to update and how much work your ADO connections are doing.

Here is the best resource I have found on this annoying problem.  It is in two parts now as the thread was getting very long.  After MS have been dithering on a fix for nearly 9 months now. Useless.  MS advice to VBA developers is pretty poor.  Roll back to W7 Pre SP1, Use the Beta version of Windows 8, Recode everything to late binding.  That is about it until they release the fix.  BAH!~

Doug,

Thanks for the assistance, I really appreciate the help.  I set up a small Access 2007 ap just to experiment with Early and Late Binding.  I am still running into a problem (Line 500).  This line was in the code from the Early Binding test which worked.  Here is the code that I have.


''' Late Binding Test
100 Dim cnn As Object
200 Set cnn = CreateObject("ADODB.Connection")

300 Dim rs As Object
400 Set rs = CreateObject("ADODB.Recordset")

500 rs.ActiveConnection = cnn  

600 rs.Open "SELECT * FROM Query1"




Thanks,
Brad

Late binding example.

This is early binding:

  Dim cnn As New ADODB.Connection

this is late binding:

Dim cnn as object
Set cnn = CreateObject("ADODB.Connection")
