While you re working in the right pane, Registry Editor doesn t highlight the current subkey in the left pane .

A control and form are configured to post back to a webpage that is different than the one that made the original request.

As we mentioned previously, signals and slots play a crucial role in Qt, enabling any two objects to communicate with each other without the need for clumsy interface definitions or callback functions. Declaring a signal requires only that the signal s object be a QObject and that the signal be declared with the signal s keyword in the class definition. In a similar vein, Qt s classic signal/slot example is that of a counter, wired to a button and slider. Our simple Qt counter class might look like what you see in Listing 4 1.

For complete control of the execution of your TestNG tests, you can configure the launch configuration by selecting Run Run or Run Debug and configure TestNG to run a specific class, group, or run based on a TestNG definition file.

Performance database. If you're not, just follow these steps: 1. Create a new Microsoft Visual C#, Class Library project in Microsoft Visual Studio 2005 (File>New>Project...>Visual C#>Class Library). 2. In the New Project dialog box, name the project and solution SQLSignature, specify C:\ as the location, and confirm. 3. Rename the file Class1.cs to SQLSignature.cs, and within it paste the code from Listing 3-5, overriding its current content. 4. Build the assembly by choosing the Build>Build SQLSignature menu item. A file named C:\SQLSignature\SQLSignature\bin\Debug\SQLSignature.dll containing the assembly will be created. 5. At this point, you go back to SQL Server Management Studio (SSMS) and apply a couple of additional steps to deploy the assembly in the Performance database, and then register the fn_SQLSigCLR and fn_RegexReplace functions. But first, you need to enable CLR in SQL Server (which is disabled by default) by running the following code: EXEC sp_configure 'clr enable', 1; RECONFIGURE; 6. Next, you need to load the intermediate language (IL) code from the .dll file into the Performance database by running the following code: USE Performance; CREATE ASSEMBLY SQLSignature FROM 'C:\SQLSignature\SQLSignature\bin\Debug\SQLSignature.dll'; 7. Finally, register the fn_SQLSigCLR and fn_RegexReplace functions by running the following code: CREATE FUNCTION dbo.fn_SQLSigCLR(@querystring AS NVARCHAR(MAX)) RETURNS NVARCHAR(MAX) WITH RETURNS NULL ON NULL INPUT EXTERNAL NAME SQLSignature.SQLSignature.fn_SQLSigCLR; GO CREATE FUNCTION dbo.fn_RegexReplace( @input AS NVARCHAR(MAX), @pattern AS NVARCHAR(MAX), @replacement AS NVARCHAR(MAX)) RETURNS NVARCHAR(MAX) WITH RETURNS NULL ON NULL INPUT EXTERNAL NAME SQLSignature.SQLSignature.fn_RegexReplace; GO

The base protocol over which Web traffic is carried is the Hypertext Transfer Protocol (HTTP). HTTP is generally carried over TCP/IP, the standard Internet Protocol, in most environments. IIS 7 supports HTTP over TCP/IP version 4 (IPv4), the more common protocol of today s Internet and the same network-level protocol as every version of IIS to date has supported. IIS 7 also adds support for HTTP over TCP/IP version 6 (IPv6), the protocol version for the next generation of Internet support.

Now you get the desired plan. You see a single seek operation within the clustered index to fetch the anchor row, followed by a seek within the covering index and a partial ordered scan, physically accessing only the relevant rows in the desired page of orders.
