If anyone can help with this problem I would be very appreciative. I have created a 256 color bitmap in my resource file. I am trying to display the bitmap on the screen. I am using the GetDIBits function with the wUsage parameter set to DIB_RGB_COLORS to retrieve the color information for the bitmap in order to create a logical palette (is this the correct procedure ... ?). However, even though the resulting bmiColors[] array contains 256 elements, all of the entries have RGB values of (0,0,0) except for the 20 entries reserved by the system. I have loaded my .EXE with a resource editor and viewed the bitmap to confirm that it is 256 color and indeed it is. Any help? This is the first time I have worked with 256 color bitmaps and I would appreciate any information anyone has to offer. Thanks in advance ...
