BUG: VB Crashes When Deselecting Multi-Selected Objects

• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0

SYMPTOMS

If you multi-select three or more controls on a form using either the CTRL key or SHIFT key and then deselect one of the controls with the Properties window closed in the integrated development environment (IDE), VB6.exe crashes.

NOTE: This problem does not occur if the Properties window is open.

RESOLUTION

To work around this problem, open the Properties window. You can open the Properties window by pressing the F4 key or clicking on the Properties Window in the View menu in the VB6 IDE.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

1. Start a Standard EXE project in Visual Basic. Form1 is created by default.



2. On Form1 place a TextBox (Text1), a CommandButton (Command1), and an OptionButton (Option1). (It does not matter which three controls you use.)



3. Close the Properties window by either clicking the "X" in the upper-right corner of the Properties window, or right-clicking the Properties window and selecting Hide.



4. Hold down the Shift key and select the three controls with the mouse.



5. Deselect one of the controls by holding the Shift key down and clicking on one of the selected controls.


This will produce a crash in VB6.exe. Typical error messages that might appear are:

An application error has occurred and an application error log is being Generated.

-or-

This program has performed an illegal operation and will be shut down.
