  I believe GetForegroundWindow will be a better way to do this.

  Hello, I am writing a dialog based program that will take screenshots while the dialog is minimized. The trigger to take a screen shot is through WM_HOTKEY. I like to use the correct API to take the a window that is active due to user's mouse click while the dialog of the program is minimized. Now, I am using : CWnd * pWnd = CWnd::GetActiveWindow() ; while the window I like to take screenshot is active after mouse click. But when I debug it, pWnd is empty and giving me error. Any idea Please help me. Thanks.

  Thanks, it worked. But I still have some more questions about measurement of my screenshots. I like to have the save the size to be (for example- 4in x 3in). Now, I am using CImage class and apply ::BitBlt () function where the parameters are only in terms of pixels.

  So, it would be really helpful if I know the conversion between pixel and inch. Pleaseeee. advise me.

  Thank a lot.
