Oh, bad, bad, bad...You should never expose C++ classes across a DLL boundary like that (interfaces not included). This isn't a C++ programming group, but if you ever want to know, just email me and I'll explain.
Anyway, you cannot call this from LabVIEW (or any other language than the specific version of the C++ compiler it was built with, and even then you have other problems). You'll need to create a wrapper DLL that exposes a method such as
unsigned int InitializeMAPS(const char*)
and have that DLL call this other once. Again, you'll want to get with whomever created that DLL to ensure you're using the same compiler and the same implementation of the STL library.
