Thanks for useful post. I've been thinking about how this is done.
One further question:
What I would like to do is have a panel within the "screen capture"
form that has total transparency, while the form itself has partial
transparency. This way the selected region is nicely highlighted.
Any ideas on how to do this?
You have to fake it, no way around that. Before you show the form you
copy the screen content to a TBitmap. Then you show that (or part of
it) on the panel you want to appear transparent.
You can make a form with a "hole" in it using the SetWindowRgn API, but
you cannot easily draw anything on top of the hole, since it is not
part of your form.
