Understanding Menu Basics in VB6

Applications use menu bars to provide an organized collection of commands that can be performed by the user. Menus can inform the user of the application's capabilities as well as its limitations. If a program has properly organized menus, users can easily find common commands as well as less-familiar features. Users can also learn shortcut keys from a well-designed menu structure.

Because menus have so many benefits to the user, a programmer should be well-versed in their creation and the functions they can provide.

Programmers can use one of two different methods to create menus in VB. The first is a built-in Menu Editor dialog box. This editor provides a fast, simple way to generate menus. Once made, all menu objects can have their properties set through program code. The other method uses the Win32 Application Programmers Interface. The Win32 API is a series of functions that are by VB and provided by the operating system. By using specialized function calls, a programmer can create menus, set properties of menus, and modify menu structure. Most of the functionality found in the API is also available using the Menu Editor. Although more difficult to work with, the API provides enhanced function calls and special capabilities not part of the VB Menu Editor. However, using the API is beyond the scope of this chapter.
