[WINAPI] Taking screenshots of windows

It has to be, hitting print-screen does exactly that.


google'd msdn print-screen screenshot

Found this link

HDC screen = CreateDC("DISPLAY", NULL, NULL, NULL);

and blit that onto a dc where you've made a bitmap the size of the screen and then write that to a file.

I know you can use GetDesktopWindow to get a handle to a window that represents the current screen... That is, your desktop, all the visible windows and so on. I imagine you could use that function along with the window rect of the window you're interested in to get a screenshot, although there may be more efficient methods as well.

I think the TS wants to have images of all individual windows, maybe to do something like OS X Exposé or something similar. I don't know the answer myself, but wanted to mention just this.

Thanks all for your answers, will try by doing what you said.

Yes Sijmen, that's exactly what I want to do, layout all my Windows in an Exposé style.

Heh, guessed that. However, you know there is already an Exposé like tool for Windows available? Google for Expose + Windows.

Good luck!
