capture a screen of a prog

[tokool]

Hi,
I am tryin to capture the screen bitmap of an application(like calc.exe) that i opened in my program using ShellExecute().
I am able to capture the entire screen using, HWND hClientWin = GetDesktopWindow() and then getting the DC from which i bitblt the contents.
How can i do this for only for a single window in the sceen, the window that the application i opened in my program generates.
Is there any other way i can open an application from my program and capture its screen bitmap.
Thanks,
Preetham

What you need is the hWnd of the application that you launch. The normal methods, such as ShellExecute etc. don't let you do this. But here's a thread over in the VB5&6 forum in which I present a method for launching an application that returns an extended PROCESS_INFORMATION structure that includes the hWnd of the shelled app. Once you've got that, it's easy.
