This function asks a property bag to delete a named property.
HRESULT SHPropertyBag_Delete ( IPropertyBag *ppb, LPCWSTR pszPropName);
The ppb argument provides the address of an IPropertyBag interface.
The pszPropName argument provides the address of a null-terminated Unicode string that names the property.
The function returns zero for success, else an error code.
If either of the ppb and pszPropName arguments are NULL, the function fails, with E_INVALIDARG as the error code. If the property bag’s Write method cannot write a VT_EMPTY type, the function fails.
The SHPropertyBag_Delete function is exported from SHLWAPI as ordinal 535 in version 6.00.
Though this function dates from 2001, it was still not documented by Microsoft in the MSDN Library at least as late as the CD edition dated January 2004.
