System.Guid	pclsid	A pointer to the initial class identifier CLSID for this property set. May be NULL, in which case it is set to all zeroes.
System.UInt32	grfFlags	The values from PROPSETFLAG Constants.
STGM	grfMode	An access mode in which the newly created property set is to be opened, taken from certain values of STGM_Constants, as described in the following Remarks section.
IPropertyStorage	ppprstg	A pointer to the output variable that receives the IPropertyStorage interface pointer.

Delete(ref Guid)

The Delete method deletes one of the property sets contained in the property set storage object.

Parameters

Type	Name	Description
