I'm not sure exactly what this means, but I'm guessing you are having trouble with the pythonwin/win32ui GetSafeHdc objects, versus those used by win32gui. I'm generally confused by DC/pyDC, PyCDC, selecting and blitting.. The goal is to get a 640x480 RGB image data string from the screen window that I can pass to pyMedia. I've tried various permutations of the below lines, but I realize that I really don't get the Windows DC/BMP/blit concepts: the order that windows-handles-DCs-blits-selects-BMPs need to be created. These lines all execute: dtwnd = win32gui.GetDesktopWindow() hdcSrc = win32gui.GetWindowDC(dtwnd) hdcDestH = win32ui.CreateDCFromHandle(dtwnd) hdcDest = win32gui.CreateCompatibleDC(hdcSrc) hBitmap = win32gui.CreateCompatibleBitmap(hdcSrc, 1024, 768) win32gui.SelectObject(hdcDest, hBitmap) destHDC = hdcDestH.GetSafeHdc() but I start having trouble with hdcDestH.BitBlt((0, 0), (1024, 768), hdcSrc, (0, 0), 0x00CC0020) TypeError: The 'O' param must be a PyCDC object and on from there. I can't say that I need anything from win32ui, since I don't know what I need at all!
