Text Generator in action

Intent Accept text entered into the top EditBox. Transfer text to the second EditBox as it is typed – illustrates use of text controls. When user hits Add button the contents of the top edit box will be transferred to a list box. Note: You must #include “stdafx.h” at the top of every *.cpp file in your server implementation.

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.
