Classes, structures, and modules contain all the code in your source file….Namespace-Level Programming Elements

Visual Basic Editor Components

• Menu bar. The VBE menu bar works just like every other menu bar you’ve encountered.
• Toolbar. The standard toolbar, which is directly under the menu bar by default, is one of four VBE toolbars.
• Project window.
• Code window.
• Immediate window.

controls in visual basic are show and inserted into the forms. The menu bar- Displays the commands you use to work with Visual Basic. Including File, Edit, View, Window, Project, Format, Debug, help, etc. The toolbar- Provide quick access to commonly used commands in the programming environment.

A function is a block of Visual Basic statements inside Function , End Function statements. Functions return values. There are two basic types of functions. Built-in functions and user defined ones. The built-in functions are part of the Visual Basic language.

Visual Basic has two types of menus, built-in and shortcut.

• Class Statement.
• Structure Statement.
• Module Statement.
• Interface Statement.

In BASIC, programming is done in a text-only environment and the program is executed sequentially. In Visual Basic, programming is done in a graphical environment. Users may click on a certain object randomly, so each object has to be programmed independently to be able to response to those actions (events).

There are three editions of Visual Studio: Community, Professional, and Enterprise.

In VB 6, you can create any program depending on your objective. For math teachers, you can create mathematical programs such as Geometric Progression, Quadratic Equation Solver, Simultaneous Equation Solver ,Prime Number Tester, Factors Finder, Quadratic Function Graph Plotter and so on.

In visual basic, we can create the Methods either by using Sub or Function keywords like as shown below. If we create a method with Sub keyword that will not allow us to return any value. In case, if you want to return any value, then you need to use Function keyword to create the method.

Commands are functions that accomplish tasks, such as printing a document, refreshing a view, or creating a new file. Menus and toolbars are convenient graphical ways to present your commands to users. Typically, related commands are clustered together on the same menu or toolbar.

The components of the IDE screen of Visual Basic. IDE stands for Integrated Development Environment. The main functions include writing, compiling and debugging code, monitoring resources.

The built-in functions are part of the Visual Basic language. There are various mathematical, string or conversion functions. In the preceding example, we use two math functions and one string function. Built-in functions help programmers do some common tasks. In the following example, we have a user defined function.

The ByVal keyword specifies how we pass the values to the procedure. In our case, the procedure obtains two numerical values, 55 and 32. These numbers are added and the result is printed to the console. A function is a block of Visual Basic statements inside Function, End Function statements.

Visual Basic statements are grouped in a block enclosed by Sub, Function and matching End statements. The difference between the two is that functions return values, procedures do not. A procedure and function is a piece of code in a larger program. They perform a specific task.

Then it opens in to a new screen as shown in figure 1 below, with the interface elements Such as MenuBar, ToolBar, The New Project dialog box. These elements permit the user to buid different types of Visual Basic applications. One of the most significant changes in Visual Basic 6.0 is the Integrated Development Environment (IDE).
