Visual Studio 2010 MFC ActiveX: How to declare and call a function in a DLL

BlueKarana asked
Last Modified: 2012-05-12
I've created an MFC ActiveX Control in VS 2010 using the MFC ActiveX Wizard.

I need to call a function in an existing DLL. How do I declare it? Where would the declaration go?

All I know about the function is the declaration given to me (see code snippet)

BTW, I'm a complete nube in VS and C++ so the more detail the better :)

Int TheFunction (
  HDC hdc,      // handle to the device context
  Int nEscape,   
  Int cbParameter,
  LPCSTR lpszParameter,  //use char* ?
  Int cbResult,
  LPSTR lpszResult      //use char* ?
