Style Dialogs are templates used by wizard dialogs to create a single interface's style for all wizard dialogs. The style dialogs can be edited normally, exactly as any other dialog, but they cannot be displayed in the setup program. The style dialog's size and controls are copied to all wizard dialogs styled with it. You can create how many style dialogs you want.

 

When your are editing a style dialog, the Style Region control is displayed. The style region control defines the region where you will be able to edit the styled wizard dialog. All the region of the styled wizard dialog outside the style region will not be able to be edited, it means that you will not be able to add controls in the styled wizard dialog outside the style region.
