Running Application Dialog. Recipe 2

Goals of Project · 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 Enter key or the OK button the contents of the top edit box will be converted to a floating point number if possible. – We do this using a server module to handle the conversion. This illustrates how to use servers, developed with console-based test stubs, with a windows program. – Note that you must #include “stdafx. h” at the top of every *. cpp file in your server implementation. Dialog. Recipe 3

Construction Steps – App Wizard · · · Run Application Wizard Select MFC App. Wizard (exe) 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. Dialog. Recipe 4

Closing Notes · · Test application by compiling and running each time you add a new Windows Message Handler Make sure you #include “stdafx. h” in every cpp file in your server code. Make sure you #include “server. h” files in the dialog implementation file where the server is used. Test each server module as a stand-alone, console-based, application, using its test stub before you call it from your interface code. Dialog. Recipe 29
