Meeting the Tools in the Visual Basic Toolbox

When you write a Visual Basic program, you first have to design the user interface. Essentially, a Visual Basic user interface consists of objects that you place on the screen and arrange in some semblance of organization so that the screen looks pretty.

The common elements of a Visual Basic user interface appear in Figure 1 and consist of the following:

  • Forms (also known as windows)

  • Buttons (such as command buttons and radio buttons)

  • Boxes (such as text boxes and check boxes)

  • Labels

  • Pictures (such as icons and graphics)
