The Command Button Control

Almost every application's form contains a command button. You can use a Command Button control to begin, interrupt, or end a process. When a user clicks a command button, it appears pushed in.

Some useful command button properties are listed below:

• Cancel: This property determines how the command button responds to the Esc key. If this property is True, the user can simulate a click by pressing the Esc key.
• Caption: This property specifies the text that appears on the command button.
• Default: This property determines how the command button responds to the Enter Key.

Only one command button on a form can be the default command button.

• Picture: This property specifies a graphic image that appears on the command button in place of a caption.

For Picture property to work, you must set the Style property to 1- Graphical.

You can add an accelerator key to a command button so that the user can select the command button by pressing the appropriate key combination.

An accelerator key is a key that, when combined with the Alt key, triggers a response.
