VB for MS-DOS KeyUp, KeyDown Events Always Occur in Pairs

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

SYMPTOMS

Visual Basic for MS-DOS incorrectly generates a KeyUp for every KeyDown event. Visual Basic for Windows correctly generates a KeyUp event only when you physically release a key.

STATUS

Microsoft has confirmed this to be a bug in the Standard and Professional Editions of 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.

MORE INFORMATION

If you hold down a key, Visual Basic for MS-DOS generates a repeating series of alternating KeyDown and KeyUp events. However, if you perform the same behavior in Visual Basic for Windows, a sequence of KeyDown events are generated, followed by only one single KeyUp event.
