Capturing the image of a application frame and contents within !

[developer2007]

Hi,

Im trying to develop and application that would will require the process ID as an input and then grab the image of the window save it as bmp.

I have tried number of approaches like using win32.dll functions for example getMainWindow( ), enumWindows( ), enumchildWindows( ).

1) The thing I that I am facing problem is that can I get the handle of onlz the frame of the window. While using enumChildWindows( ) I get handles of all the controls as well how is it possible to distinguish that the handles belongs to the frame.

2) Using enumWindows does not gives me all of the windows displayed on desktop kinda strange. I filtered them out using the process ID

IDEA: Just like when you press Alt+PrtScr you get the image of active window. all I want is that I get all of the image of all the opened instances of that perticular process. example: VLC player/MSN Messenger if I select open from file menu now I should get the previous main window as well as then newly opened form.

Please help out, any idea to solve the problem would be realy appreciated.

Thanks.
