Is there a way to capture the entire contents of a window? Not just the part of the window that is showing but also the part of the window you can only see if you scroll (known as "below the fold")? Suppose I want to capture the entire contents of a multipage document in notepad in one image.
I've been using the code described in: http://www.developerfusion.com/code/4630/capture-a-screen-shot/ and Capture screenshot of active window?
Using:
_processList = Process.GetProcessesByName("notepad");
if (_processList.Length > 0) return _processList[0].MainWindowHandle
By getting the window handle of an instance of notepad, I can easily capture the portion of a web page that is visible. But I would like to be able to capture the contents of the entire portion of a scrollable window. Does such a representation even exist in memory anywhere, or does it only come into being once a window scrolls?
Note: it seems this question has been asked, but never really answered for anything other than browsers and web pages: Capture a scrolling window contents screenshot
