Efficient way to grab the screen
Hi all ! I ve searched the forums for screen capture posts and found one where galathea says the CreateWindowDC API function should do the job given the desktop window handle f.e. This makes perfect sense yes (thanks galathea).
But will it properly capture the AVI overlays and some other funky effects ? I need an exact whole image of the screen (portion of it) because i am implementing a remote control service.... For this reason i am willing to go to any depth of the WinAPI just to get the image a) fast and b) without holes. DirectX, whatever - i will eat it !
Am I dreaming ? :-)
Efficient way to grab the screen
BitBlt is the fastest way you could grab a screen, unless i guess you try writing code at the framebuffer level.
