Not excatly what you're searching for, but I made something like that once.

I have a program start a 'child-program', where the parent can't be close
until the child returns it close message to the parent.
You can use the TApplication.OnAppMessage (correct name ???) to capture all
messages, and the FindWindow to get the handle of another window if you know
its classname and caption.

MyHandle := FindWindow(blah blah)
PostMessage( MyHandle, WM_USER+whatever, data...)

and use the AppMessage to capture these telling whether it can close or not.

Not that if yuo set the Handled paramater to True, then the message will not
be carried out.

As I don't know what specifications yuo excatly have I don't know whether
this helps you. Hopefylly it gives a hint or idea.

See http://homestead.dejanews.com/user.sonnich/files/child.zip as an
example.

God luck with it !
