BUG: Changing Caption of Menu Item Corrupts Shortcut Key Text

ID: Q92940

The information in this article applies to:

Microsoft Visual Basic Standard and Professional Editions for MS-DOS, version 1.0

SYMPTOMS

At run time, if you change the caption property of a menu item that has a shortcut key assigned to it, the text defining the shortcut key to the right of the menu item is corrupted. However, the shortcut key sequence continues to work.

WORKAROUND

To work around the problem, append CHR$(0) to the new Caption setting as in this example:


   MItem1.Caption = "First" + CHR$(0)

Or have a second menu, and set its visible property to false. Then at run time, set the second menu's visible property to true and the first menu's visible property to false.

STATUS

Microsoft has confirmed this to be a bug in Microsoft Visual Basic for MS-DOS, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
