This example shows you how to use the PrintWindow API to view the visual output of a window which may, or may not be visible on the screen.

It can therefore be used as an alternative to BitBlt for a more complete screenshot project.

MSDN - PrintWindow

http://msdn.microsoft.com/en-us/library/dd162869%28VS.85%29.aspx

The PrintWindow function copies a visual window into the specified device context (DC), typically a printer DC.

BOOL PrintWindow(

HWND hwnd,

HDC hdcBlt,

UINT nFlags

);

Parameters

hwnd - A handle to the window that will be copied.

hdcBlt - A handle to the device context.

nFlags - The drawing options. It can be one of the following values:

nil - Entire Window is copied to hdcBlt

                PW_CLIENTONLY - Only the client area of the window is copied to hdcBlt.

Only Delphi source code is included in the archive.
