Controls are objects you can place on forms and in other containers such as frames and picture boxes. Controls can take the form of images, pictures, command buttons, labels, frames, and text boxes. The form you put your controls on is also considered a control. In addition to their graphically



Appealing presence, controls serve other functions as well. Visual Basic controls have events, properties, and methods associated with them. Properties of controls are considered their attributes.

For example, some properties of a word processor might include font size, fore color, back color, and alignment.

You can change the properties of controls when you’re designing your program (also known as design-time changes) by clicking on the control or by selecting it from the drop-down list box.

You can also modify a control’s properties through program code during runtime (when your program is running). You can start to see that the properties describe a control or object.
