Developers of installation packages can author a user interface containing the controls discussed in this topic. For information on how to add a particular control to a dialog box, see the topic for that control and read the section Adding Controls and Text.

Some controls, such as CheckBox and ComboBox, are associated with a property specified in the Property column of the Control table. A user changes the value of this property by interacting with the control. Passive controls, such as Billboard and bitmap, are not associated with such a property.

For security, private properties cannot be changed by a user interacting with the user interface. For a property to be set by the user interface, it needs to be a public property and in uppercase. See also About Properties.

In some cases a control may be redrawn incorrectly when canceling out of a dialog. This has to do with the order in which the controls receive WM_PAINT messages after the Cancel dialog is removed. To fix this, try changing the order of the controls in the Control table.
