Therefore before discussing the available tools for running a VB. Mono can be run on many operating systems including Android, BSD, i OS, Linux, OS X, Windows, Solaris and UNIX. Net programming language, let us look a bare minimum VB. Read Key() End Sub End Module A variable is nothing but a name given to a storage area that our programs can manipulate. Net has a specific type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable. The Dim statement is used for variable declaration and storage allocation for one or more variables. Button Dim last Time, next Time As Date Module variables Ndataypes Sub Main() Dim message As String Console. An enumeration is a set of named integer constants. Net, constants are declared using the Const statement. All these languages can access the framework as well as communicate with each other. Net framework consists of an enormous library of codes used by the client languages like VB. Microsoft provides the following development tools for VB. Visual Basic Express and Visual Web Developer Express edition are trimmed down versions of Visual Studio and has the same look and feel. In this tutorial, we have used Visual Basic 2010 Express and Visual Web Developer (for the web programming chapter). NET applications cross-platform, but also to bring better development tools to Linux developers. We will discuss date types and Classes in subsequent chapters. Following is a valid statement: The constants refer to fixed values that the program may not alter during its execution. Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal. The constants are treated just like regular variables except that their values cannot be modified after their definition.

The following code demonstrates a hypothetical use of the directive: Module mydirectives Public Class External Source Tester Sub Test External Source() #External Source("c:\vbprogs\directives.vb", 5) Console.

Write Line("Exam Questions for Class VIII") #Else Console.
