PixelChecksum in minimized window

[Vegar]

Hello..

is there any way to PixelChecksum in a minimized or non active window?

[dantay9]

I don't beleive this is possible because pixel checksum checks the pixels currently displayed on the screen. If the window is not shown, the correct pixels won't be returned.

hmm, is there anything else then i can use?

i want to make a func when a certain pixel change in a certain window witch is most of the time not active or minimized.

Thnx for all help

I believe there is a way to get a screenshot of a minimzed window...read ti somewhere on the forums, maybe you could use a similar method....

I am pretty sure you can't take a screenshot of a minimized window. A screenshot is just that, it takes a picture of what is currently on your screen, not what will be on your screen after you click a window.

Sorry I meant there is a windows dll that will return images of minimized GUI's... I just forget what it is....
