This is the UNO wrapper used in the service com.sun.star.bridge.OleBridgeSupplierVar1. Key features: DISPIDs are passed out blindly. That is in GetIDsOfNames is no name checking carried out. Only if Invoke fails the name is being checked. Moreover Invoke tries to figure out if a call is made to a property or method if the flags are DISPATCH_METHOD | DISPATCH_PROPERTYPUT. If something has been found out about a property or member than it is saved in a MemberInfo structure hold by an IdToMemberInfoMap stl map.
