How to create a model file in Matlab with dll compiled in Microsoft visual studio 2010

Hi All,

Let me explain my scenario. We have a code compiled in mingw compiler and with the dll generated we are able to create model files in matlab.

Now we wanted to try it with vb compiler. So we did copying the .c and .h files to vb and modified/corrected all syntax related errors. Finally with no build/linker errors we got a .dll file. With that when we tried to create model file in MATLAB we got

Mex File Entry Point missing... Invalid MEX file.

Please do suggest a idea how should I proceed now.
