Note: You must #include “stdafx.h” at the top of every *.cpp file in your server implementation.

4. Construction Steps - Summary • Run Application Wizard • Select MFC Application project • Select Dialog-based • Pull controls from control palette onto dialog in Resource View. • Add message handlers for every event you want to handle. • You can either right-click on dialog class in Class View to add handler • Or you double click on the control you want to handle, e.g., EditBox or Button. • When you double click, you get a handler for the most common message for that control. That may or may not be what you want. • You get more control by using the first method. The second method is faster. • Add code in message handlers, perhaps by calling a server module providing the computational engine for your interface. • Compile, Edit, and Run repeatedly until you get the behavior and appearance you want.
