I am a novice VB user trying to use VB to control an Access 2.0
database.  I own both VB3 and Access2 and I recently downloaded
COMLYR.EXE from ftp.microsoft.com/softlib/mslfiles.  It seems
that all the necessary DLL's have been replaced or added
(including MSAJT200.DLL); however, I am still getting an "incompatible
database version" message upon trying connect to an Access 2.0
database (the error occurs when I try selecting a recordsource
for a data control in VB.)  Am I leaving something out?  Am I
missing something important?  Will I graduate?

Access Visual Basic Advisor Dec./Jan. issue has a great article on
using VB3 and Access2. You must update VB.INI and the .INI that you
send with your VB app. In the both .INI files modify the [Installable
ISAM] and [Paradox ISAM] sections like this:

[Installable ISAM]
Paradox 3.X=C:\VB\PDX200.DLL ;Path of the Paradox 3.x driver
Paradox 4.X=C:\VB\PDX200.DLL ;Path of the Paradox 4.x driver
FoxPro 2.0=C:\VB\XBS200.DLL  ;Path of the Microsoft FoxPro 2.0 driver
FoxPro 2.5=C:\VB\XBS200.DLL  ;Path of the Microsoft FoxPro 2.5 driver
dBase III=C:\VB\XBS200.DLL   ;Path of the dBase III driver
dBase IV=C:\VB\XBS200.DLL    ;Path of the dBase IV driver
Btrieve=C:\VB\BTRV200.DLL     ;Path of the Btrieve driver

If you use attached Paradox tables, add this to your .INI files:

[Paradox ISAM]
ParadoxNetStyle=3.x ;Required to open Paradox databases

In the SETUPWIZ.INI file, make these changes:

[ACCESS] ; Key used by Setup Wizard
; Jet database engine files
file1=MSABC110.DLL
file2=MSAJT200.DLL
file3=VBDB300.DLL
file4=SHARE.EXE:1  ; Jet database engine DLLs require 'SHARE.EXE /L:500
                   ; in autoexec.bat
file5=MSAJT112.DLL

If using Crystal Reports, read ACC2COMP.TXT file for instructions to
upgrade Crystal Reports to run with Access 2.0 .mdb files.

Hope this helps. More info in the article.
