when i use setwindowrgn api with activex the api makes the background of the control transparent but does not clip the assigned region(s) during design time so the transparent section overlaps other controls (during design time).... is there a way around this?

i also used createroundrectrgn, selectcliprgn and offsetcliprgn api's to create the assigned region and a second region to bitblt onto the assigned region when end user clicks the activex during runtime.

assigned region = what i used with setwindowrgn
