mand window. This behavior produces a result similar to that of pressing the Enter key
when typing in a text editor window—the cursor is repositioned at the beginning of the next
line in the file. Program execution terminates when the program encounters the End Sub
in line 8.
Now that we have presented our first console application, we provide a step-by-step
explanation of how to create and run it using the features of the Visual Studio .NET IDE.
1. Create the console application. Select File > New > Project... to display the
New Project dialog (Fig. 3.2). In the left pane, select Visual Basic Projects,
and, in the right pane, select Console Application. In the dialog’s Name field,
type Welcome1. The location in which project files will be created is specified
in the Location field. By default, projects are saved in the folder Visual Studio
Projects inside the My Documents folder (on the Windows desktop). Click
OK to create the project. The IDE now contains the open console application, as
shown in Fig. 3.3. Notice that the editor window contains four lines of code provided
by the IDE. The coloring scheme used by the IDE is called syntax-color
highlighting and helps programmers visually differentiate programming elements.
Keywords appear in blue, whereas text is black. When present, comments are colored
green. In Step 4, we discuss how to use the editor window to write code.
2. Change the name of the program file. For programs in this book, we change the
name of the program file (i.e., Module1.vb) to a more descriptive name. To rename
the file, click Module1.vb in the Solution Explorer window, this step
will display the program file’s properties in the Properties window (Fig. 3.4).
Change the File Name property to Welcome1.vb.
