Hi, I created a class. In the class, I created a method. In the method, I am trying to initialize the COM by calling ::CoInitializeEx(NULL,COINIT_APARTMENTTHREADED); and then I created another test problem to test the class. When I build the project, I didn''t get any compilation error, but at run time, when the method that has the CoInitializedEx is called, it gives me a MissingMethodException. I think maybe it can not find the dll it needs. Am I right? Anyone has any idea? Thanks a lot. Ricky

I looked in the help....

Header: Declared in objbase.h.
Library: Use ole32.lib.

are you linking to the above lib?

I think I did. I went to the properties->linker->input->Additional Dependencies to add the Ole32.lib already. That''s what I have there.

nochkclr.obj mscoree.lib Ole32.lib Uuid.lib

I am using VS.NET 2003. Actually, Do I have to install anything else besides VS.NET in order to use that?
