An ADO.NET provider is simply a set of ADO.NET classes (with an implementation of Connection, Command, DataAdapter, and DataReader) that s distributed in a class library assembly. Usually, all the classes in the data provider use the same prefix. For example, the prefix Oracle is used for the ADO.NET Oracle provider, and it provides an implementation of the Connection object named OracleConnection.

Our implementation of CreateChildControls() calls into routines responsible for adding the child controls representing the header and the HTML table of the control, which are named BuildHeader() and BuildTable(), respectively It is also the linkage point for evaluating the X and Y dimensions of the table BuildHeader() demonstrates the use of an HtmlGenericControl control from the System WebUIHtmlControls namespace to render the <h3> content This control was chosen due to its lack of built-in styling capabilities to keep the example simple We build up the string content of the control by using the StringBuilder class This class is a more efficient way of building up strings in NET than concatenating literals as Strings, because StringBuilder uses a buffer Variables of type String are immutable, and a concatenation operation actually builds a third string from the two strings brought together, literal or otherwise.

The ADO.NET classes are grouped into several namespaces. Each provider has its own namespace, and generic classes such as the DataSet are stored in the System.Data namespaces. Table 7-1 describes the namespaces. Table 7-1. The ADO.NET Namespaces

recently spoke with Craig Bell, owner of the networking services firm Momentium Technologies, about a new client engagement The client, called Bravo Corp for this discussion, had just reviewed its security and data backup guidelines and determined that security was too lax, and they were not making any backups of important company information Bravo Corp took the right step in hiring Momentium to revamp its network security and to put the appropriate data backup routines in place, but they did it about a week too late Before Momentium got a chance to even look at the network infrastructure, an irate ex-employee hacked into Bravo Corp s systems and deleted their entire data repository There s an FBI investigation into the incident, but even if they find the culprit, Bravo Corp can t recover its lost data.

You can also create rules that are applied to HTML tags automatically. To do this, specify the tag name for the rule name. Here s a rule that affects all <h2> tags on the page that uses the stylesheet: h2 { ... } Although this automatic stylesheet application sounds useful, it s less convenient in ASP .NET because you re usually dealing with controls, not individual HTML tags. You can t always be certain what tags will be used to render a given control, so it s best to explicitly specify the rule you want to use through the class name. Using stylesheets accomplishes two things. First, it standardizes your layout so that you can quickly format new pages without introducing minor mistakes or idiosyncrasies. Second, it separates the formatting information so that it doesn t appear in your web pages at all, allowing you to modify the format without tracking down each page or recompiling your code. And although CSS isn t a .NET-centric standard, Visual Studio still provides rich support for it.

For those who were worried about the HtmlTextWriter class and its efficiencies, the Render() and Write() methods write to a buffer, so there aren t any performance concerns about calling these methods multiple times Once we have built up the string content, we next use the InnerHtml property to easily load the HTML information inside the <h3> control The final step is to add the HtmlGenericControl to the Controls collection of our new custom server control Building the HTML table in the BuildTable() method follows the well worn process of programmatically building up the HtmlTable control s child content The result is almost an exact image of the user control version of the table This is a good indication of the strength of custom controls when it comes to dynamic generation The declarative advantages of the user control are not as powerful when content is built on the fly..
