PrintWindow Example - Delphi Source Code
Post date: Mar 2, 2010 8:00:52 PM
Compiled: Delphi 2007
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
The PrintWindow function copies a visual window into the specified device context (DC), typically a printer DC.
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.
