Article ID: 137232

APPLIES TO


This article was previously published under Q137232

SYMPTOMS

The program displays the wrong colors or causes a general protection (GP) fault when using a DIB section and a custom palette in a memory DC.

CAUSE

There is a problem in Windows 95 where an internal palette structure is not set up until the palette is selected into a screen DC.

RESOLUTION

If you use logical palettes with bitmaps created by CreateDIBSection, select the palette into a screen DC when the palette is created. Then the palette can be used normally with Screen DCs as well as with DIB sections.

STATUS

Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base when it becomes available.
