When you open the IDE or create a new project, a blank form is displayed on the screen. You design your application's user interface (UI) by placing and arranging visual components, such as windows, menus, and dialog boxes, from the Tool palette onto the form. 

Once a visual component is on the form, you can adjust its position, size, and other design-time properties, and code its event handlers. The form takes care of the underlying programming details. 

The following topics describe some of the major interface tasks, such as working with forms, creating component templates, adding dialog boxes, and organizing actions for menus and toolbars.
