The window of the resulting application looks as follows:

The dialog window of the sample application.

First of all, the program lists the names of all available video capture devices available on the system in the list box listBox1. All video capture devices names are added to the listBox1, by setting the listBox1.DataSource attribute to IcImagingControl.Devices.

C#
      
private void Form1_Load(object sender, System.EventArgs e)
{
    listBox1.DataSource = icImagingControl1.Devices;
}

        

When the user clicks "Open Device", the program stops the live video stream (.LiveStop). It then proceeds to gets the selected video capture device, using (listBox1.SelectedItem). And finally, live image data stream of the device is displayed using .LiveStart:

C#
      
private void buttonOpen_Click(object sender, System.EventArgs e)
{
    TIS.Imaging.Device dev = listBox1.SelectedItem as TIS.Imaging.Device;

    if( dev != null )
    {
        icImagingControl1.LiveStop();
                icImagingControl1.Device = dev;
        icImagingControl1.LiveStart();
    }
}

private void buttonClose_Click(object sender, System.EventArgs e)
{
    Close();
}
