Obtaining the Status of a Capture Window
The following example uses the SetWindowPos function to set the size of the capture window to the overall dimensions of the incoming video stream based on information returned by the capGetStatus macro in the CAPSTATUS structure.
CAPSTATUS CapStatus;
capGetStatus(hWndC, &CapStatus, sizeof (CAPSTATUS));
SetWindowPos(hWndC, NULL, 0, 0, CapStatus.uiImageWidth,
CapStatus.uiImageHeight, SWP_NOZORDER | SWP_NOMOVE);
