Perhaps you have noticed the logo or window that often appears while program is loading. This initial form is called splash screen.
Professional applications use splash screens to tell the user that the program is loading and starting.
It can make a large application appear to load and run faster, since something appears on the screen while the rest of the application loads.
You can create your own splash screen or use the splash screen template included woth Visual Basic. In the add form dialog box, choose the Splash screen to add a new form; then modify the form as you need.
