To build an application we'll need a project.  A project is a technological part of the system we're developing ( also called solution ).  Different project types exists, examples of project types are console applications, window applications and web applications.

A solution is the collection of projects, together with some configuration between these projects, needed to create our system.

All examples and exercises on this website are made for console applications.

These are applications with limited possibilities for input and output, and are mainly inteded for commandline programs.  Other types of projects, for instance window applications, have a more extended GUI ( "Graphical User Interface" ), but are harder to define.

Console applications are used on this website to maintain all examples clear and simple.

A module or class is used as a codingblock were we'll define our sourcecode.

A class can also be used to define a object oriented construction.

After installing Visual Studio, you have to create a console application.

In this application you can insert the sourcecode documents you've downloaded from this website.  You can do this by clicking the "Add Existing Item ..." option, in the "Project" menu.  The appearing dialog can be used to select the document(s) to add.

All you need to do know is to let the project ( console application ) know what module ( or class ) needs to be executed.  This startup object can be set in the options of the project.  In Visual Studio these settings can be reached by option "<name-of-the-project> Properties ..." in menu "Project".  On the "Application" tab, in the "Startup object" option, choose the name of the module ( or class ) you want to execute.
