Every SQL Server database has its own associated transaction log. The transaction log provides recoverability in the event of failure, and ensures the atomicity of transactions. The transaction log accumulates all changes to the database so that database integrity can be maintained in the event of an error or other problem. Because of this arrangement, all SQL Server databases consist of at least two files: a database file with an .mdf extension and a transaction log with an .ldf extension.

In addition to HTML UI elements, a given *.htm file may contain blocks of script code that will be emitted into the response stream and processed by the requesting browser. There are two major reasons why client-side scripting is used: To validate user input before posting back to the web server To interact with the Document Object Model (DOM) of the target browser Regarding the first point, understand that the inherent evil of a web application is the need to make frequent round-trips (termed postbacks) to the server machine to update the HTML rendered into the browser. While postbacks are unavoidable, you should always be mindful of ways to minimize travel across the wire. One technique that saves round-trips is to use client-side scripting to validate user input before submitting the form data to the web server. If an error is found (such as not supplying data within a required field), you can prompt the user of the error without incurring the cost of posting back to the web server (after all, nothing is more annoying to users than posting back on a slow connection, only to receive instructions to address input errors!). In addition to validating user input, client-side scripts can also be used to interact with the underlying object model (the DOM) of the web browser itself. Most commercial browsers expose a set of objects that can be leveraged to control how the browser should behave. One major annoyance is the fact that different browsers tend to expose similar, but not identical, object models. Thus, if you emit a block of client-side script code that interacts with the DOM, it may not work identically on all browsers.

RadialGradientBrush works similarly to the LinearGradientBrush. It also takes a sequence of colors with different offsets. As with the LinearGradientBrush, you can use as many colors as you want. The difference is how you place the gradient. To identify the point where the first color in the gradient starts, you use the GradientOrigin property. By default, it s (0.5, 0.5), which represents the middle of the fill region.

ASP.NET provides the HttpRequest.Browser property, which allows you to determine at runtime the capacities of the browser that sent the current request.
