capturing images on tablets with dual webcams

I have built an application that will capture and upload images taken from a tablet webcam to a database, the app works on tablets that only have one webcam but refuses to load the driver from tablets that have dual webcams. The code I'm using is straight from another code project solution, I'm using code from here

Does anybody know if there is a fix for tablets sporting dual webcams?

public void Start(ulong FrameNum)
{
    try
    {
        // for safety, call stop, just in case we are already running
        this.Stop();

        // setup a capture window
        mCapHwnd = capCreateCaptureWindowA("WebCap", 0, 0, 0, m_Width, m_Height, this.Handle.ToInt32(), 0);

        // connect to the capture device
        Application.DoEvents();
        SendMessage(mCapHwnd, WM_CAP_CONNECT, 0, 0);
        SendMessage(mCapHwnd, WM_CAP_SET_PREVIEW, 0, 0);

        // set the frame number
        m_FrameNumber = FrameNum;

        // set the timer information
        this.timer1.Interval = m_TimeToCapture_milliseconds;
        bStopped = false;
        this.timer1.Start();
    }

    catch (Exception excep)
    { 
        MessageBox.Show("An error ocurred while starting the video capture. Check that your webcamera is connected properly and turned on.rnn" + excep.Message); 
        this.Stop();
    }
}
