CWiauPropertyList::SetAccessSubType method

The CWiauPropertyList::SetAccessSubType(INT,ULONG,ULONG) method resets a property's access and subtype.

Syntax

HRESULT SetAccessSubType(
  INT   index,
  ULONG Access,
  ULONG SubType
);

Parameters

index

Access

SubType

Specifies the property subtype, one of WIA_PROP_FLAG, WIA_PROP_LIST, WIA_PROP_RANGE, or WIA_PROP_NONE. The first three constants indicate, respectively, that a property is a set of flag values, a list of values, or a range of values. The fourth constant indicates that a property is none of these.
