COM Automation and Visual C++ 6

[Stuart]

Hello,
I am in the process of creating a C++ socket server to execute builds for our build system the problem that I am running into is that I can not create the builder COM Object. I have had no problem creating the Application COM object.
I can create the builder com object in visual basic but would prefer to do it in my C++ instead of calling out to a Visual Basic COM Object I create.

Here is some example code

This code works for creating the application object
Declaraion:
VisBuildSvr::IApplicationPtr m_VisualBuild_AppPtr;


HRESULT hr= pVisBuildApp.CreateInstance (__uuidof(VisBuildSvr::Application));


This code does not work for creating the builder object
Declaration
VisBuildSvr::IBuilderPtr m_BuilderPtr;


HRESULT hr=pVisBuilderPtr.CreateInstance (__uuidof(VisBuildSvr::Builder));

Any help would be greatly appreciated
Thank you in advance,
Stuart
