When stopping a debugging session for an application within the Visual Basic 5.0 IDE, you may receive the following message:

"An application error has occurred and an application error log is being generated.

Exception: access violation (0xc0000005), Address: <xxxxxxxx>"

This occurs if the application uses a UserControl that contains a TextBox control positioned within a container-like a Tab control.


An alternative to upgrading to Visual Basic 5.0 Service Pack 2 is to use the RichTextBox control to provide multi-line 'TextBox' functionality (as described in Section 2 of the README.TXT file included on the Visual Basic 5.0 CD-ROM).


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 2.

For more information on the Visual Studio 97 Service Pack 2, please see the following article in the Microsoft Knowledge Base:

Result: An access violation occurs.
