WM_PRINTCLIENT message
-
Hi, Has anybody used WM_PRINTCLIENT message? I m using the following SendMessage call..... SendMessage(hWnd, WM_PRINTCLIENT, (WPARAM) hDCMem, PRF_CLIENT | PRF_ERASEBKGND | PRF_CHILDREN ); but this returns a black window. Any clues? Thanks, peenu.

WM_PRINTwith thePRF_CLIENTflag. Not all window types support theWM_PRINTCLIENTmessage, orWM_PRINTfor that matter. I assume you're setting your memory DC up correctly - creating and selecting a bitmap for it, etc. Your syntax is correct, so if your DC is setup correctly and it still doesn't work, then the window you're sending the message to probably doesn't handle the message, and there's not much you can do about it.Ryan
