Problem:
Executing a GUI application using a manifest file causes the windows and controls to display with the Windows XP style but the tab controls look bad. Specifically, the background of labels, radio-buttons and check-boxes doesn't match the tab color.
Resolution:
The problem is that with XP style the tab is not the same as the window's background color, is not a solid color but graduated (lighter at the top, darker at the bottom) and labels, radio-buttons and check-boxes take their background color from the main window. The result is an unattractive tab presentation.
Setting the transparent property fixes the problem for labels but radio-buttons and check-boxes don't have a transparent property.
If one can't avoid placing radio-buttons and check-boxes on tabs a workaround is to place a frame on each tab page and set the frame color and fill to be the same as the main window.
The attached program, tabmod.cbl, demonstrates this workaround.
