Depends on a few things:
What version of Delphi are you using?
What operating system are you running on?
Does is have to be the client area _only_ that is transparent?

For D6 & greater, and apps running on Win 2K or later, setting the
whole form to a (semi) transparent state is trivial - just play with
the AlphaBlend and AlphaBlendValue properties of the form.

For other cases it is possible, but more involved. I don't remember
the details but I have seen such code on the Delphi groups before, so
Google should find it.
