Device Information Property Constants
Device Information Properties are properties that describe the setup and installation of the device. These properties are available through the IWiaDevMgr or IWiaDevMgr2 interfaces and also through the root item. Device information properties are prefixed with "WIA_DIP_" (Device Information Property) and are supplied by Windows Image Acquisition (WIA). For scripting purposes, these constants use the prefix "DeviceInfo" and are part of the WiaDeviceInfoPropertyId enumerated type. The corresponding member name from that script enumeration appears in parentheses next to the C/C++ constant name in the following list.
