Hwndc = capcreatecapturewindow (
(Lpstr) "My capture window", // window name if Pop-up
Ws_child | ws_visible, // window style
0, 0,160,120, // window position and dimensions
(Hwnd) This-> m_hwnd,
(INT) 1/* child id */); // create a video window

// Fok = sendmessage (hwndc, wm_cap_driver_connect, 0, 0l );
: Sendmessage (hwndc, wm_cap_driver_connect, 0, 0l); // connect to the driver
: Sendmessage (hwndc, wm_cap_driver_get_caps, sizeof (capdrivercaps), (long) (lpvoid) & capdrvcaps); // get the capture capability of the driver

// Or, use the macro to connect to the msvideo DRIVER:
// (Capdriverconnect (hwndc, 0) // use a macro to connect to the driver, the same below

// Capdrivergetcaps (hwndc, & capdrvcaps, sizeof (capdrivercaps ));

Cappreviewrate (hwndc, 66); // rate, in milliseconds, set the Capture Rate
Cappreview (hwndc, true); // starts preview, preview
