Text Generator in action

Intent • Accept text entered into the top Edit. Box. • Transfer text to the second Edit. Box 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. , Edit. Box 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.
