Hi all i am writing a custom control derived from UserControl in ManagedC++.This class is using third party unmanaged C++ classes(from VTK library) internally. When i tried to build the control i got the following following error. D:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\ObjIdl.h(7408): error C2872: 'IDataObject' : ambiguous symbol Please somebody help me how to get rid of this error. Thanks in advance Regards Kriohna

Usually this error happens when the compiler is not able to determine which symbol you are refering to. A typical example is when you have two methods with the same name but defined in diferent namespaces used in the project. If this is the case try to use full namespaces when refering to them.
