You can name forms in many ways, but the more meaningful the name is, the better it is for others to read and understand your visual basic program.

btnSubmit
btnReset
imgBaloon
chkMale

Control Properties

Every control object have properties that uniquely describes that control. You can change the properties both in design view as well as in run time.

Some property values are necessary and global to all controls such as Name, Caption, Visible, etc. and some are very specific to a control, no other control can have that property.

For example,

A checkbox has a property called value – checked, unchecked, grayed. These are unique to check boxes.

Radio buttons have a property called value – true or false. These will check or uncheck the radio option and unique properties for radio buttons.

Methods and Events

Visual basic methods and events are visible in a code editor. You can choose a control and then the event for the control. Finally, choose an appropriate method as a response.
