PRB: VB5 Components Distribute Improperly with VB4 Setup Kit

ID: Q160968

The information in this article applies to:

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

SYMPTOMS

Microsoft Visual Basic 4.0 distributions built using the Setup Wizard will not work properly if created on a system that also has Microsoft Visual Basic Control Creation Edition version 5.0 installed.

CAUSE

Microsoft Visual Basic Control Creation Edition 5.0 installs components that are incompatible with Microsoft Visual Basic 4.0's Setup Wizard. These components require different runtime components than the earlier Microsoft Visual Basic 4.0 versions. The new controls that are affected are:

COMCTL32.OCX
COMDLG32.OCX

The files upon which these controls depend are:

ASYCFILT.DLL OLEAUT32.DLL OLEPRO32.DLL STDOLE32.TLB

Changing the SWDEPEND.INI file for Microsoft Visual Basic 4.0's Setup Wizard usually allows the appropriate files (above) to be included with the distributed diskettes. However, OLEAUT32.DLL is a System file that is commonly in use by the operating system, even with no other applications running. This situation requires a system reboot to update OLEAUT32.DLL properly. The Setup Wizard included with Microsoft Visual Basic 4.0 does not support rebooting.

RESOLUTION

There are two possible workarounds for this behavior.

NOTE: If a Microsoft Visual Basic 4.0 application has already been distributed to a target machine with the new .OCX components (as described above), you must uninstall the application and manually remove or replace the updated components. This is necessary because the workarounds below make use of the Microsoft Visual Basic 4.0 components. The Setup Wizard is incapable of replacing a later version of a component with an earlier one.

Workaround 1

Prior to installing Microsoft Visual Basic Control Creation Edition version 5.0, copy the following components:

COMCTL32.OCX
COMDLG32.OCX
OLEPRO32.DLL
MFC40.DLL
MSVCRT40.DLL

to the following folder:

C:\Program Files\Microsoft Visual Basic\Setupkit\Kitfil32\sys32

Microsoft Visual Basic 4.0's Setup Wizard always looks at the above folder first when searching for dependent files.

Next, when you create distribution disks with Microsoft Visual Basic 4.0's Setup Wizard, follow these steps:

Deselect the COMCTL32.OCX and COMDLG32.OCX references in step 5.

Manually add COMCTL32.OCX and COMDLG32.OCX from the above folder during step 7.

Again, this will only be necessary when creating distribution disks for applications that use the COMCTL32.OCX or COMDLG32.OCX controls.

Workaround 2

Another workaround is to maintain a pure Microsoft Visual Basic 4.0 system (one without Microsoft Visual Basic Control Creation Edition version 5.0 installed) for the purpose of creating Setup distribution files.

STATUS

This behavior is by design.
