PSCreateSimplePropertyChange Creates a simple property change.
PSEnumeratePropertyDescriptions A wrapper API that calls the schema subsystem's IPropertySystem::EnumeratePropertyDescriptions. This function retrieves an instance of the subsystem object that implements IPropertyDescriptionList, to obtain either the entire list or a partial list of property descriptions in the system.
PSFormatForDisplay Gets a formatted, Unicode string representation of a property value stored in a PROPVARIANT structure. The caller is responsible for allocating the output buffer.
PSFormatForDisplayAlloc Gets a formatted, Unicode string representation of a property value stored in a PROPVARIANT structure. This function allocates memory for the output string.
PSFormatPropertyValue Gets a formatted, Unicode string representation of a property value stored in a property store. This function allocates memory for the output string.
PSGetImageReferenceForValue Gets an instance of a property description interface for a specified property.
PSGetItemPropertyHandler Retrieves a property handler for a Shell item.
PSGetItemPropertyHandlerWithCreateObject Retrieves a property handler for a Shell item.
PSGetNamedPropertyFromPropertyStorage Gets a value from serialized property storage by property name.
PSGetNameFromPropertyKey Retrieves the canonical name of the property, given its PROPERTYKEY.
PSGetPropertyDescription Gets an instance of a property description interface for a property specified by a PROPERTYKEY structure.
PSGetPropertyDescriptionByName Gets an instance of a property description interface for a specified property name.
PSGetPropertyDescriptionListFromString Gets an instance of a property description list interface for a specified property list.
PSGetPropertyFromPropertyStorage Gets the value of a property as stored in serialized property storage.
PSGetPropertyKeyFromName Gets the property key for a canonical property name.
PSGetPropertySystem Gets an instance of the subsystem object that implements IPropertySystem.
PSGetPropertyValue Gets a property value from a property store.

PSPropertyBag_ReadPOINTL Retrieves the coordinates stored in a property contained in a specified property bag.
PSPropertyBag_ReadPOINTS Retrieves the coordinates stored in a property contained in a specified property bag.
PSPropertyBag_ReadPropertyKey Reads the property key of a property in a specified property bag.
PSPropertyBag_ReadRECTL Retrieves the coordinates of a rectangle stored in a property contained in a specified property bag.
PSPropertyBag_ReadSHORT Reads the SHORT data value of a property in a property bag.
PSPropertyBag_ReadStr Reads the string data value of a property in a property bag.
PSPropertyBag_ReadStrAlloc Retrieves details about the allocation or releasing of memory for a string that is stored in a property contained in a specified property bag.
PSPropertyBag_ReadStream Reads the data stream stored in a given property contained in a specified property bag.
PSPropertyBag_ReadType Reads the type of data value of a property that is stored in a property bag.
PSPropertyBag_ReadULONGLONG Reads a ULONGLONG data value from a property in a property bag.
PSPropertyBag_ReadUnknown Reads a given property of an unknown data value in a property bag.
PSPropertyBag_WriteBOOL Sets the BOOL value of a property in a property bag.
PSPropertyBag_WriteBSTR Sets the BSTR value of a property in a property bag.
PSPropertyBag_WriteDWORD Sets the DWORD value of a property in a property bag.
PSPropertyBag_WriteGUID Sets the GUID value of a property in a property bag.
PSPropertyBag_WriteInt Sets the int value of a property in a property bag.
PSPropertyBag_WriteLONG Sets the long value of a property in a property bag.
PSPropertyBag_WritePOINTL Stores the coordinates of a point in a property in a property bag.
PSPropertyBag_WritePOINTS Stores the coordinates of a point in a property in a property bag.
PSPropertyBag_WritePropertyKey Sets the property key value of a property in a property bag.
