The following example uses the capPreviewRate macro to set the frame display rate for preview mode to 66 milliseconds per frame and then uses the capPreview macro to place the capture window in preview mode.
// Create the capture window.
HWND hWndC = capCreateCaptureWindow(TEXT("My Capture Window"),
WS_CHILD | WS_VISIBLE, 0, 0, 160, 120, hwndParent, nID);
capPreviewRate(hWndC, 66); // rate, in milliseconds
capPreview(hWndC, TRUE); // starts preview
// Preview
capPreview(hWndC, FALSE); // disables preview
