A simple

STDAPI DllRegisterServer(void)
{

}

should do the trick.

Then you call it like:

typedef HRESULT (STDAPICALLTYPE* FuncDllRegisterServer)();

HMODULE hDll = AfxLoadLibrary(nameOfDll);
if (hDll==0)
{
  // Failed to load the dll
}
else
{
  FuncDllRegisterServer registerServer = (FuncDllRegisterServer)GetProcAddress(hDll, "DllRegisterServer");	
  if (registerServer == 0)
  {
    // DLL has no DllRegisterServer function
  }
  else
    registerServer();
}
