WIA_IPA_ITEM_FLAGS

The WIA_IPA_ITEM_FLAGS property contains the descriptive flags for a WIA item.

Property Type: VT_I4

Valid Values: WIA_PROP_NONE

Access Rights: Read-only

Remarks

The WIA item flags are the same as those in the lObjectFlags parameter of the wiasCreateDrvItem service utility function. The WIA service creates and maintains the WIA_IPA_ITEM_FLAGS property.

An application reads WIA_IPA_ITEM_FLAGS to determine a WIA item's descriptive flag values.

The following table describes the flags that are obsolete in Windows Vista and later versions of the operating system but are valid with Microsoft Windows XP.
