"Screen Scraping" the contents displayed by a window
Posted on 2004-08-01
This problem seems to be hard. I've tried to find a solution on my own, but without luck.
There is an application running on Windows XP that displays various graphics. I know nothing about it. The only thing I have is the window's handle.
I want to be able to analyse the graphics displayed in the window. It would be nice for example if I could call a function called getBitMap(myWindowsHandle) and have returned an object or the data which is the bitmap of the window contents. This data must exist somewhere if Windows is displaying it, right?
