I've noticed that in OLE containers and in flash there are areas which act like buttons. but they don't show up as buttons on windows spy programs - they don't show up at all !

i guess there must be a window rect area set up and when it determines the mouse is over this area, it animates a bitmap, or actions some code if mouse clicks within the area.

my question is, how do i determine the 'hit area' of the button if i don't have the source code.

any help or pointers would be greatly appreciated !

thanks
