screen capture ...

[iza]

where could i find a good doc/ref on how to code an app that would capture the screen and paste the captured bitmap in a specified window - i've been looking in msdn workshop, and the msdn library, and searched thru the posts here, and the faqs ... - or could someone help ?

here's what i got so far :
// to capture the screen
HDC hdcScreen = CreateDC("DISPLAY", NULL, NULL, NULL);
HDC hdcCompatible = CreateCompatibleDC(hdcScreen);
HBITMAP hbmScreen = CreateCompatibleBitmap(hdcScreen,
GetDeviceCaps(hdcScreen, HORZRES),
GetDeviceCaps(hdcScreen, VERTRES));
HGDIOBJ image=SelectObject(hdcCompatible,hbmScreen);
if (BitBlt(hdcCompatible,
0, 0,
200, 200,
hdcScreen,
0,0,
SRCCOPY))

{
here is the problem !!! i want an image on the calling window to update with the values that have just been copied with BitBlt ...
}
}
