After a handle to a WIA session has been established, you need to select the WIA source to use for acquiring images. This is because WIA does not feature default device selection. Use the WiaSession.EnumDevices function to determine the WIA sources available on the system. This function enumerates all available WIA sources and calls the EnumDevicesEvent event for each WIA source found, retrieving its ID, name and description.
LEADTOOLS WIA offers two functions for selecting the WIA source to use for acquiring images:
Once a device is selected, use the GetSelectedDevice method to get the selected device ID as a string. Use the SelectedDeviceType property to determine the type of the device currently selected at runtime to determine whether it is a scanner, camera or streaming video device.
