C++ Class Library DLL Help

Hello there. I'm new at DLLs in .net, and am just looking for some simple guidance. I want to make a DLL, that basically has a few member functions that take in a value then return it. Essentially what i want to do is below. I'm also planning on using this DLL in another VC++ MFC client application. I'm using VS2005 also. I can build the DLL and add it as a reference in my client app, but I cannot access the methods of the class (i can recognize the namespace and class in the client application). Could someone please give me a hand? Also, if anyone knows of somewhere i can find a simple DLL and client app available for d/l i'd be extremely grateful. Thanks a bunch.

  4.     {
  5.         // TODO: Add your methods for this class here.
  6.         int ret_val(int val){return (val*2);}
  7.     };
  8. }
