17. Press F5 to run the program. (Alternatively, a program can be run from the
menu by pressing Alt/R/S or by clicking on the Start icon , the twelfth icon
on the Toolbar.) Notice that the dots have disappeared from the form.
18. The cursor is at the beginning of your name. Press the End key to move the cursor
to the end of your name. Now type in your last name, and then keep typing.
Eventually, the words will scroll to the left.
19. Press Home to return to the beginning of the text. You have a full-fledged word
processor at your disposal. You can place the cursor anywhere you like to add
or delete text. You can drag the cursor across text to create a block, place a copy
of the block in the clipboard with Ctrl+C, and then duplicate it anywhere with
Ctrl+V.
20. To terminate the program, press Alt+F4. Alternatively, you can end a program
by clicking on the End icon , the fourteenth icon on the Toolbar, or clicking
on the form’s close button .
21. Select the text box, activate the Properties window, select the MultiLine property,
click on the down-arrow button, and finally click on True. The MultiLine
property has been changed from False to True.
22. Run the program, and type in the text box. Notice that now words wrap around
when the end of a line is reached. Also, text will scroll up when it reaches the
bottom of the text box.
23. End the program.
24. Press Alt/F/V, or click on the Save Project icon to save the work done so far.
A Save File As dialog box appears. See Figure 2-8. Visual Basic creates two
disk files to store a program. The first, with the extension .frm, is entered into
the Save File As dialog box and the second, with the extension .vbp, into a Save
Project As dialog box. Visual Basic refers to programs as projects.

25. Type a file name, such as testprog into the “File name” box. The extension .frm
automatically will be appended to the name. Do not press the Enter key yet.
(Pressing the Enter key has the same effect as clicking Save.) The selection in
the “Save in” box tells where your program will be saved. Alter it as desired.
(Suggestion: If you are using a computer in a campus computer lab, you probably
should use a diskette to save your work. If so, place the diskette in a drive,
say, the A drive, and select 3 1/2 Floppy (A:) in the “Save in” box.)
