I have been using DSNless Tabledefs in my Access application for a long time now. It uses these to attach to our SQL server. Today I noticed that my .mdb file was larger than I expected (40M) and that repairing and compacting didn't shrink it much. So I imported all the objects into a new database. The size came down 24M. I was happy for about 5 minutes.
My users got errors, which turned out to be because the DSNless tabledefs were now attempting to use a Trusted Connection. My code which creates the connection uses an explicit username and password and sets Trusted_Connection=No; In my tabledefs in the new database, the username and password have been removed from the Connect String, and Trusted_Connection now equals YES.
I tried recreating the tabledefs, but each time my parameters are being overwritten. My code sets the tabledef attributes to dbAttachSavePWD, and even this is being overwritten with a value of 537001984
Can anyone suggest why this is happening? It all worked fine before.
