Adding Controls to Forms
Most forms contain controls that display information to the user or collect information from the user. These controls are most often added to the form at design time. You can add a control to a form at design time in several ways:
- From the View menu, select Toolbox.
- On the Toolbox window, select the Win Forms tab.
- Double-click the appropriate control.

Anchoring Controls on Forms
The controls on a resizable form should resize and reposition properly when the user resizes the form. In previous versions of Visual Basic, this required extensive coding or a custom component to carry out control resizing and repositioning. In Visual Basic .NET, you can use the Anchor property of Windows Forms controls. The Anchor property determines to which edges of the container a control is bound. When a control is anchored to an edge, the distance between the control s closest edge and the specified edge will remain constant. Say for example that you have a combo box that is anchored to the top, left, and right edges of a form (see Figure 7.2).
