RE: IDsObjectPicker AttributesToFetch mystery

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I recently stumbled on the problem myself.
here you have a basic example in C++ of how to get additional attributes

The important points here are :
Create an array of pointers to unicode string each containing the attribute
name you wish to retrieve.Be sure to get the names right! If unsure write a
quick program to dump all the attributenames for a given object for instance
"user" using
IDsDisplaySpecifier->GetAttributeADsType.
Next invoke the dialog
On return pvarFetchedAttributes holds an array of variants in the same order
as the attributenames directory. If the attribute does not exist the type of
the variant=VT_EMPTY

Hope it helps.
