======================================================================
-------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Learning, Professional and Enterprise Editions,
   for Windows, version 5.0
 - Microsoft Visual Basic Standard, Professional and Enterprise Editions,
   32-bit only, for Windows, version 4.0
--------------------------------------------------------------------------

SYMPTOMS
========

If Microsoft Visual Basic version 5.0 and Microsoft Visual Basic version
4.0 32-bit are installed on the same machine, inconsistent behavior is
observed when using Microsoft Visual Basic 4.0.

CAUSE
=====

Microsoft Visual Basic version 5.0 is designed to replace Microsoft Visual
Basic version 4.0 and to upgrade the earlier components (including .OCX
controls) to newer versions. Maintaining both versions of Visual Basic on
the same machine is not recommended because many of the new version 5.0
features and components are not supported in version 4.0. The following
Microsoft Visual Basic 4.0 32-bit files are replaced with updated Microsoft
Visual Basic 5.0 components:

   acmsetup.exe     msmask32.ocx     p2irdao.dll
   comctl32.ocx     mssetup.dll      p2sodbc.dll
   comdlg32.ocx     msvcrt20.dll     picclp32.ocx
   compress.exe     msvcrt40.dll     richtx32.ocx
   crpe32.dll       odbc16gt.dll     scp32.dll
   crxlat32.dll     odbc32.dll       sqlsrv32.dll
   crystl32.ocx     odbc32gt.dll     tabctl32.ocx
   ctl3d32.dll      odbcad32.exe     u2ddisk.dll
   dbgrid32.ocx     odbccp32.cpl     u2dmapi.dll
   dblist32.ocx     odbccp32.dll     u2fcr.dll
   dbnmpntw.dll     odbccr32.dll     u2fdif.dll
   drvssrvr.hlp     odbcint.dll      u2frec.dll
   ds16gt.dll       ODBCJI32.DLL     u2frtf.dll
   ds32gt.dll       ODBCJT32.DLL     u2fsepv.dll
   mci32.ocx        odbcstf.dll      u2ftext.dll
   mfc40.dll        ODBCTL32.DLL     u2fwks.dll
   mscomm32.ocx     P2BBND.DLL       u2fxls.dll
   mscpxl32.dll     p2bdao.dll       vbajet32.dll
   msmapi32.ocx     p2ctdao.dll      vbskco32.dll

These components behave differently than the components released with the
32-bit version of Microsoft Visual Basic 4.0.

RESOLUTION
==========

Create a dual-boot system in which one boot of the operating system will be
installed with Microsoft Visual Basic 4.0 32-bit and the other will be
installed with Microsoft Visual Basic 5.0. See the REFERENCES section of
this article for more information.

STATUS
======

This is the intended behavior of Microsoft Visual Basic 5.0.

================
