As was just mentioned, you will be creating a managed C++ application. Select New, Project from Visual Studio .NET's File menu. Select Visual C++ projects from the list of project types and select the Managed C++ application project template. Give your project the name ObjectSerialization and click OK to create the project.
The project you are going to create consists of a main Windows Form. Contained on that form is a text box that will be used to dump the values of various data members so that you don't need to view them in the debugger each time you run your application. Serialization and deserialization will occur when you click the corresponding form's button. Also, in order to demonstrate serialization customization, two text boxes will be used to set the values of the internal member variables. Listing 24.1 shows the necessary code for the main user interface of the form.

If you decided to write in all the code yourself rather than download the project from the Sams Web site, the probability that you entered at least one error is pretty high. Compile and run your application to ensure everything is working. You should see a form similar to the one in Figure 24.1 when your application is running.
