The information in this article applies to:

- Microsoft Visual Basic Control Creation Edition for Windows, version 5.0 
- Microsoft Visual Basic Learning Edition for Windows, version 5.0 
- Microsoft Visual Basic Professional Edition for Windows, version 5.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you exit Visual Basic 5.0, an Invalid Page Fault may occur.

CAUSE
=====

This crash is caused by a problem in the way Visual Basic 5.0 destroys command
bars during shut down.

RESOLUTION
==========

There are several workarounds for this problem. However, they may not work in
all cases.

Re-order the Entries in the VBADDIN.INI
---------------------------------------

This is a trial-and-error process where you open up the VBADDIN.INI in a text
editor such as notepad.exe and change the order of the lines. This causes Visual
Basic to load and shut down the add-ins in a different order and may bypass the
problem. However, if you add or remove an add-in at any later time, the problem
could resurface. The VBADDIN.INI file is located in your Windows directory.

For instance, you may have a VBADDIN.INI that looks something like this:

     [Add-Ins32]
     TabOrder.Connect=0
     DataFormDesigner.DFDClass=0
     VBSDIAddIn.Connect=0
     DataToolsAddIn.Connect=0
     AppWizard.Wizard=0
     WizMan.Connect=0
     ClassBuilder.Wizard=1
     AddInToolbar.Connect=1
     ControlWiz.Wizard=1
     DataFormWizard.Wizard=0
     ActiveXDocumentWizard.Wizard=0
     PropertyPageWizard.Wizard=1
     APIDeclarationLoader.Connect=0
     VisualCompMgr.Connect=0
     RVBAddInMenus.Connector=1
     RVBAddIn.Connector=0

Through trial and error, you may find that the problem goes away when the
VBADDIN.INI is arranged as follows:

     [Add-Ins32]
     RVBAddInMenus.Connector=1
     AddInToolbar.Connect=1
     TabOrder.Connect=0
     DataFormDesigner.DFDClass=0
     VBSDIAddIn.Connect=0
     DataToolsAddIn.Connect=0
     AppWizard.Wizard=0
     WizMan.Connect=0
     ClassBuilder.Wizard=1
     ControlWiz.Wizard=1
     DataFormWizard.Wizard=0
     ActiveXDocumentWizard.Wizard=0
     PropertyPageWizard.Wizard=1
     APIDeclarationLoader.Connect=0
     VisualCompMgr.Connect=0
     RVBAddIn.Connector=0

Unfortunately, this workaround doesn't always work. When you are testing out your
changes to the VBADDIN.INI, make sure you use the following procedure. In order
for your changes to take effect, you must start Visual Basic after saving your
changes to the VBADDIN.INI:

1. Shut-down Visual Basic 5.0.

2. Save changes to the VBADDIN.INI.

3. Start Visual Basic 5.0.

4. Shut-down Visual Basic 5.0.

Move Add-In Command Bars to the Main Toolbar
--------------------------------------------

Drag all Add-In toolbar buttons to the Standard toolbar using the toolbar
customize feature of the Visual Basic development environment. This gets rid of
some command bars and may by-pass the problem:

1. Launch Visual Basic 5.0.

2. From the Add-Ins menu, select the Add-In Manager and ensure that the Add-In
  Toolbar is selected.

3. From the View menu, select Toolbars > Customize.

4. Drag each of the Add-In toolbar buttons to the Standard toolbar.

5. Deselect the Add-In toolbar from the Customize dialog box.

6. Close the Customize dialog box.

7. From the Add-Ins menu, select the Add-In Manager and ensure that the Add-In
  Toolbar is deselected.

8. Close Visual Basic 5.0.

Disable Add-Ins Before Exiting Visual Basic 5.0
-----------------------------------------------

It may be possible to work around the problem by shutting down all the active
add-ins manually prior to exiting Visual Basic 5.0. To shut down an add-in, use
the following procedure:

1. Select the "Add-Ins\Add-In Manager..." menu to bring up the Add-In Manager.

2. De-select the add-ins that you wish to unload.

3. Press OK to unload the add-ins.
