BUG: GPF/UAE If Multi-Select Controls w/ No Common Properties

• The Standard and Professional Editions of Microsoft Visual Basic for Windows, versions 2.0 and 3.0

SYMPTOMS

A general protection (GP) fault or unrecoverable application error (UAE) may occur when you select multiple custom controls that have no properties in common.

For example, if you add the VBSQL.VBX custom control from the Microsoft SQL Server Programmer's Toolkit for Visual Basic and then select it and the Timer control while holding down the CTRL key, you will encounter a GP fault or UAE.

CAUSE

The problem occurs because there are no properties in common between the Timer control that comes with Visual Basic and the VBSQL.VBX control. This usually isn't a problem because most custom controls contain at least the Tag property. There are only a few exceptions.

STATUS

Microsoft has confirmed this to be a bug in both the Standard and Professional Editions of Microsoft Visual Basic versions 2.0 and 3.0 for Windows. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
