IPropertyStorage::DeletePropertyNames method (propidlbase.h)
The DeletePropertyNames method deletes specified string names from the current property set.
Syntax
HRESULT DeletePropertyNames(
[in] ULONG cpropid,
[in] const PROPID [] rgpropid
);
Parameters
[in] cpropid
The size on input of the array rgpropid. If 0, no property names are deleted.
[in] rgpropid
Property identifiers for which string names are to be deleted.
Return value
This method supports the standard return value E_UNEXPECTED, in addition to the following:
Remarks
For each property identifier in rgpropid, IPropertyStorage::DeletePropertyNames removes any corresponding name-to-property ID mapping. An attempt is silently ignored to delete the name of a property that either does not exist or does not currently have a string name associated with it. This method has no effect on the properties themselves.
Note All the stored string property names can be deleted by deleting property identifier zero, but cpropid must be equal to 1 for this to be a valid parameter error.
