|WiaDeviceType.Scanner||The device is a scanner.|
|WiaDeviceType.DigitalCamera||The device is a camera. Note that this type of device is not supported by Windows Vista and later.|
|WiaDeviceType.StreamingVideo||The device contains streaming video. Note that this type of device is not supported by Windows Server 2003, Windows Vista, or later.|
Flag that determines certain actions of the WIA image acquisition selection dialog box. Possible values are:

This function creates and displays the Select Device dialog box so the user can select a WIA device for image acquisition.
Particular types of devices may be displayed to the user by specifying the device types through the deviceType parameter.
If only one device meets the specification, the SelectDeviceDlg does not display the Select Device dialog box. Override this behavior and force the SelectDeviceDlg to display the Select Device dialog box by passing NoDefault as the value for the flags parameter.
|WIA 2.0 does not support cameras or streaming video.|
|You do not need to call this method if you are using the high-level AcquireSimple method, since it handles session initialization, session end, and device selection automatically.|
