Exporting static template members from a DLL

I'm trying to create a DLL, and part of my interface includes a class template that contains a static member (simplified version follows):

template<class T>
class Event {
public:
    Event() { ... }

    class Handler {
    public:
       void handle( const T& ) = 0;
       // ...
    };

    static void Register( Handler* pHandler ) {
        ms_registry.push_back( pHandler );
    }

    // ...

private:
    static vector<Handler*> ms_registry;
};

Obviously, the ms_registry member needs to be defined for each instantiation of the template. I have one instantiation defined in the library, something like:

class MyEvent : public Event<MyEvent> {
public:
    // ...
};

This is perfectly legal (though a little weird), and it works great for new subclasses that I create *outside* the DLL (because defining the ms_registry member for subclasses defined outside the DLL is no problem). However, I can't seem to export the definition of the MyEvent::ms_registry field from the DLL (the definition is located in a .cpp file). I have to define it, or the link stage of building the DLL fails, but I can't get clients of the DLL to link with the DLL's definition. HELP!!!

If you are using VC 5.0++, look at the knowledge base article
"HOWTO: Exporting STL Components Inside & Outside of a Class" (ID Q168958)

I think what you need to do is explicitly insantiate the MyEvent class in your CPP file.
