2.2 PropertyType

The PropertyType enumeration represents the type of a property in a property set. The set of types supported depends on the version of the property set, which is indicated by the Version field of the PropertySetStream packet. In addition, the property types not supported in simple property sets are specified as such. PropertyType is an enumeration, which MUST be one of the following values:

This type is declared as follows:

 typedef unsigned int PropertyType;
