Three variables are required by this example. withandle and exehandle serve the same purpose as they did in the first example, liveMode is used to keep track of whether live video is on or off:
[C#] private IntPtr withandle; private IntPtr exehandle; private bool liveMode = false; [Visual Basic] Private withandle As IntPtr Private exehandle As IntPtr Private liveMode As Boolean = False
