Yes, big thoughts !!! I solved the problem in my VBA/DAO program this sunday, after reading and reading docs/archive. The problem is that the Postgres ODBC driver doesn't implement the SQLSetPos call. This call is needed by DAO, when updating/deleting rows in an ODBC connection, if ... (that's where your platform problem occurs : it was working good for me on an NT, but not on a W98SR2). This SQLSetPos call is related to the cursor library used by your ODBC connection. You can see the full error message using the \SQL.LOG trace of the ODBC driver manager. The trick is to select another cursor library, and I did this with the following VBA code : Set wrkSlave = CreateWorkspace("wrkSlave", "", "", dbUseODBC) wrkSlave.DefaultCursorDriver = dbUseODBCCursor Check to VBA doc for the full explanation. You can choose another cursor driver if you which. I use this client-side ODBCCursor because it seemed much more fast than the server-side ones I tried, but YMMV. I hope I can save you many hours of tearing your hair...

When I attempt the refresh method of an ADO data control in VB (MDAC 2.5/DCOM98 or Windows NT) I get an automation error, the ODBC-supplied error messages are as follows in SQL tracing: Numerous: DIAG [S1096] [Microsoft][ODBC Driver Manager] Information type out of range (0) Numerous: DIAG [S1C00] Unknown statement option (Set) (10) Now, what follows is an explanation that a guy at Microsoft sent me: [S1096] is server specific and by looking at the log insicates that we're querying for the availability of static and keyset cursors at the server and it's returning an error. [S1C00] is Unknown, the driver doesn't understand what the client's asking for in some contextx. OK, this is where it gets good: it only happens on certain machines--some running 98, some running Windows NT. I have two Nt machines on which my program runs fine with ver 6.40.00.07 of the driver. Any thoughts? Thanks, Ted Wallingford
