Doesn't the default RC.EXE (Microsoft Resource Compiler) offer any more customization with Shape controls?
The WinAsm Studio resource editor seems to leave them as a simple anonymous control with no properties or visual representation. It's either a matter of "just never getting around to it," or perhaps "strange/unexpected problems," or what I'm guessing the reason is: "no one gives a crap about the Shape control
Anyway, the shape control would be useful for me in implementing a small dialog which is trying to show a color which the user chose, so I can manipulate the WM_CTLCOLOR message to change its background color quickly and easily. Right now I'm just using a Static control and using the WM_CTLCOLORSTATIC message to do it. It would be nice however, if I could make it a circle or some other shape instead of a rectangle. (although, admittedly, I'm not completely sure if it would work properly. It might just make a square colored background with a black circle painted on top of it. )
