WM_CAP_DRIVER_CONNECTThe WM_CAP_DRIVER_CONNECT message connects a capture window to a capture driver. You can send this message explicitly or by using the capDriverConnect macro.
WM_CAP_DRIVER_CONNECT
wParam = (WPARAM) (iIndex);
lParam = 0L;
Parameters
iIndex
Index of the capture driver. The index can range from 0 through 9.
Return Values
Returns TRUE if successful or FALSE if the specified capture driver cannot be connected to the capture window.
Remarks
Connecting a capture driver to a capture window automatically disconnects any previously connected capture driver.
