How to Use Microsoft’s Visual Studio .NET 2005 Compiler

Microsoft’s Visual Studio .NET 2005 is designed to make state of the art Windows and .NET applications. Microsoft provides one and only one way to emulate an older DOS C++ program, a
Win32 Console Application .Even this form of program is really a full-fledged Windows application, but can appear as if it were an ordinary C++ DOS program. This Appendix explains
How to create and work with a DOS Console Application .

A Windows Application is a C++ program that runs in windows with a graphical user interface, such as dialogs, edit controls, list boxes, pictures, and so on. These types of programs generally require the knowledge of this eBook, plus Advanced Data Structures or its equivalent, C++ Object Oriented Programming. A DOS Console application is a basic C++ program that can be run from a command prompt in a DOS window. However, the Integrated Development Environment or IDE is normally used to run our applications under development. Please note carefully that a Console Application is not a Windows Application and does not have a graphical user interface such as dialogs, edit controls, and list boxes. All output is simply text lines of 80 characters maximum. Console applications are used in all of the beginning C++ programming courses.

C++ DOS Console Applications

Normally, we think of a program as having one or more source files (with the .cpp or .h file extensions) and the compiler created executable, the .exe file. However, Visual Studio always thinks in terms of programming “solutions.” A “solution” represents the solving of a user programming problem or application and consists of all of the files necessary to fully implement
it. Suppose that we wish a “solution” that displays the message “Hello World!” on the screen so that we can learn how to use the Visual Studio package. Visual Studio is always going to place all of the files that make up that solution into a folder of your choice on some drive of your choice. The key point is that all solution files reside in a folder. Normally, for beginning programmers, each program or “solution” should be stored in its own separate folder. Where are these program folders located? If you are working at home, my suggestion is to begin by making a top-most folder to store all of the program or “solution” folders for a course. Use Explorer to make a folder such as this. C:\Cs125

If you are working in the labs at school, you should place all of your program or “solution” folders beneath the folder they have designated, such as D:\Student Note: do not use your local H: drive. It only holds 20M which translates to just a couple complete programming assignments. Another, perhaps better, school solution is to purchase a thumb USB port drive which can store much larger volumes of data. With your top-most folder created, you are ready to begin making the “Hello World” program or “solution.” There are three approaches that are used: “I am beginning a brand new program” or “I wish to continue working on an existing program” or “I am bringing my files from home to School and I want to work on my program here at School for a while.” Let’s examine these three situations in turn.
