Hi All!

I need to grab a print-screen of a window my app is using. I'm not using max2D but instead I'm rendering SOW onto a canvas- and this seems to make grabbing a screenshot impossible.

So I'd like to try a workaround- Force a printscreen of the window, and grab and save that instead.

I tried bitblt yesterday, no luck. it copes to another canvas OK but the saved file is just black, but a true windows print-screen grabs the image fine.

How would I go about doing this?

Thanks for your help,
