To create data-driven Web sites, for example, you (Starting a web site)
To create data-driven Web sites, for example, you need a pretty specific list of things: HTML, CSS, ASP.NET, a data source (such as SQL Server), and at least one programming language (such as C#). An IDE like Visual Web developer brings all those technologies together under one roof, so to speak, so you can get all your work done in one program window. (What a concept.) You ve seen a similar (but unrelated) term before: In hard drives, IDE stands for Integrated Device Electronics. But that concept is in no way related to software development. In hard drives, it just means that all the electronics the disk needs to operate are contained within the drive s case. Control When used as a noun within the context of programming, the term control refers to things in a program, or on a page, that allow users to control the action. For example, open any Windows dialog box and you see a bunch of text boxes, drop-down menus, check boxes, and buttons. All of these are relatively small, simple controls. In a more general sense, a control can be anything on the page that a user interacts with. In Visual Web Developer s Toolbox, each item actually represents a control that you can drag and drop onto a page. As a developer, you choose which controls users will see, and can program what happens when a user interacts with a control. Code Code is the text that forms the instructions for the computer, written in some programming language such as C# or Visual Basic. It has a different function from text that s typed in a human language. Unlike regular text, code uses no sentences or paragraphs. Instead, code consists of statements (lines) written in the programming language rather than in a human language. Figure 13-1 shows an example of some C# code. When you write in (say) English, you can get away with murder in terms of spelling and punctuation; even if the text would make your composition teacher cry, your human recipient will probably still be able to figure out what you mean simply by studying the context of the message. (If you ve spent any time in online forums, you ve no doubt seen the extent to which people can get away with worse-than-iffy spelling and punctuation.)
