Problem loading my dll with VC++ 2K8

Hello,
I have a strange issue, indeed I made a dll with Qt.

And I made a main.cpp file to load this dll (I use GetProcAddress and LoadLibrary).

I can compile this file with g++ (using the Qt prompt) and visual. The compilation works for both (g++ & Visual).
The g++ exec works perfectly but the visual one has a memory violation error.

I have a link for all the files I made :

Thanks

Run it in the debugger.
