64 Part I Getting Started with Microsoft Visual Basic 2010

4. Type Randomize, and then press ENTER.

The Randomize statement is added to the program and will be executed each time

the program starts. Randomize uses the system clock to create a truly random

starting point, or seed, for the Rnd statement used in the Button1_Click procedure.

As I mentioned earlier, without the Randomize statement, the Lucky Seven program

produces the same string of random spins every time you restart the program. With

Randomize in place, the program spins randomly every time it runs, and the numbers

don’t follow a recognizable pattern.

5. Run the new version of Lucky Seven, and then save the project. If you plan to use the
   new version a lot, you might want to create a new .exe file, too.


6. When you’re finished, click Close Project on the File menu.

The files associated with the Lucky Seven program are closed.
