This can be used to display different bitmaps depending on the state of the
push button (normal, disabled) or option button (checked, unchecked,
disabled).
The format of the bitmap requires a certain format so that Windows can
extract the correct bitmap according to the current state. For pushbuttons
you need a 3-state bitmap for option buttons a 4 state bitmap. The size of
the bitmap must be a multiple of 3 resp. 4 with a black (?) line as
separator. See the sample.
But I have to admit that I don't know what is the third state for a push
button resp. the 4th state of an option button.
HTH,
Stefan
