C++ calling a dll

Ok lets say we have a function we want to call in C++. We would normally do this:

/* declare the function */
int MyFunction(char*,int);
int main(void)
{
   returnMyFunction("hello", 5);
}

/* our function */
int MyFunction(char*,int)
{
   /* do something */
   return 0;
}
----------------------------------------------------------------------------------

But in our case that same function is in a dll. Ok let's see how we do it.
Your dll is located on the C:\ drive for example and is named "MyDLL.dll". It
contains a function called "MyFunction". Create a function that calls the dll's function like so:

int CallMyDLL(void)
{
    /* get handle to dll */
   HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\MyDLL.dll");

   /* get pointer to the function in the dll*/
   FARPROC lpfnGetProcessID = GetProcAddress(HMODULE (hGetProcIDDLL),"MyFunction");

   /*
      Define the Function in the DLL for reuse. This is just prototyping the dll's function.
      A mock of it. Use "stdcall" for maximum compatibility.
   */

   typedef int (__stdcall * pICFUNC)(char *, int);

   pICFUNC MyFunction;
   MyFunction = pICFUNC(lpfnGetProcessID);

   /* The actual call to the function contained in the dll */
   int intMyReturnVal = MyFunction("hello", 5);

   /* Release the Dll */
   FreeLibrary(hGetProcIDDLL);

   /* The return val from the dll */
    returnintMyReturnVal;
}

You can just copy and paste the above into your project and change the prototyping to match your dll's function.
