Description: Two statements that are very important to know about when constructing programs are the Option and Imports statements. The Option statement sets a number of options for the rest of your code, and the Imports statement imports namespaces into your code, making them more readily available.

Description: You combine assemblies to form .NET applications, and although we won't deal with them directly very often, we need to get the terminology down. An assembly holds the Intermediate Language modules for your application. When you create an application in VB .NET and run it, VB .NET creates one or more assemblies, which are run by the CLR. That is, assemblies are how your applications interact with the .NET framework instead of the EXE or DLL files of VB6.

Description: When you save a solution, it's given the file extension .sln (such as WinHello.sln), and all the projects in the solution are saved with the extension .vbproj. Here's a list of the types of file extensions you'll see in files in VB .NET, and the kinds of files they correspond to; the most popular file extension is .vb. This is a useful list, because if VB .NET has added files to your solution that you haven't expected, you often can figure them out by their file extension:

Description: When starting programs from the Debug menu's Start item, Visual Basic launches the program while staying in the background; if there's a problem, Visual Basic will reappear to let you debug the program's code. That's useful for development, of course, but when your program is ready to go and to be used by others, you hardly want them to have to launch your program from Visual Basic.

Description: VB .NET is only one component of a revolution in Windows-the .NET framework. This framework provides the new support for software development and operating system support in Windows, and it's more extensive than anything we've seen in Windows before. The .NET framework wraps the operating system with its own code, and your VB .NET programs actually deal with .NET code instead of dealing with the operating system itself. And it is specially designed to make working with the Internet easy.

Description: Rather than asking what's new, it would almost be easier to ask what's not new in VB .NET. The changes are extensive. We can't cover all the changes from Visual Basic 6.0 in a single article, but it's worth taking a look at them in overview here, in one place, so you get an idea of how things are different.

Description: This first and most common type of loop used in almost all program languages is the For loop. Let's see how it works in VB.net

Description: The Select Case statement is another way to test what is inside of a variable. When there is small number of variables are used we can use this Select case statement.

Description: It's time to start coding that database program. But wait a moment-how are you going to handle the data? It's just a simple program, so you don't want to start tangling with the full database techniques. An array would be perfect; how do you set one up?

Description: You've decided to lead the way into the future by letting your users type in sentences as commands to your program. Unfortunately, this means that you have to parse (i.e., break down to individual words) what they type. So what was that string function that lets you break a string into smaller strings again? We'll get an overview of string handling in this topic. Strings are supported by the .NET String class in Visual Basic. You declare a string this way:
