WINDOWS
Summary:
The class-specific window styles for button controls (BS_*) are
mutually exclusive, as are the class-specific window styles for static
controls (SS_*). In other words, they cannot be OR'd together as can
most styles for edit controls, list boxes, and combo boxes.
For example, the following style is invalid:
BS_OWNERDRAW | BS_AUTORADIOBUTTON
A button control is either owner-draw or it is not. In the same
manner, the following style is also invalid:
SS_LEFT | SS_GRAYFRAME
WINDOWS.H defines button and static styles sequentially (1, 2, 3...),
instead of as individual bits (1, 2, 4...) as other control's styles
are defined. If sequential styles are OR'd together, the resulting
style may be completely different from that intended.
