Re: Problem connecting from Windows 9x/Me

Hi,

I've tried creating a table link in Access automatically (so my users won't
have to). Unfortunately, it still unable to connect.

I've done further investigation on the ODBC trace logs, and it seems the
difference is here:

Success:

sir             fffaa095-fff4e88d       EXIT  SQLDriverConnectW  with
return code 0 (SQL_SUCCESS)

sir             fffaa095-fff4e88d       EXIT  SQLDriverConnectW  with
return code -1 (SQL_ERROR)
======================================

However, I noted that the connection from a Windows 2000 machine (which
never encounter this issue) uses SQL_DRIVER_COMPLETE_REQUIRED parameter as
well (and it connects just fine). So probably that's not the culprit.

A discussion I found mentioned about the ODBC driver using Unicode,
therefore causing problems on Windows9x/Me machines.
I wonder if that's the case here as well.

Those are my findings so far.
Any help would be greatly appreciated.


Thanks,
Harry
