| Visual Basic .NET supports a variety of features that can be used to build sophisticated, yet easy-to-use, graphical user interfaces with Windows Forms. In this chapter, we will explore how menus , toolbars , and status bars can be added to an application. We will also examine several different types of controls, including calendar controls, range controls and list controls. By selecting the proper type of control to communicate with the user, the user's interaction with the application can be made more pleasant. In addition, validation and verification of the user's input by the application can be enhanced. For example, when a user must enter a department name, allowing them to select the name from a list rather than having them type the department name (and possibly misspelling it) reduces errors. |
