In a similar manner, you can support dynamic unpivoting . To see how the technique works, first run the following code, which creates and populates the CustOrders table with pivoted total yearly order values per customer .

Multilink PPP, and Bandwidth Allocation Protocol (BAP)

Classic ASP had an interesting way of marking code segments within a page . ASP always supported the classic script tags (<script> </script>) where anything found between the <script> tags was treated as executable code . However, in classic ASP, the script blocks were sent to the browser, and it became the browser s job to run the script . In addition to clientside script blocks, a classic ASP Web page could define script blocks to be interpreted on the server . These methods often performed tasks such as database lookups . Causing code to execute on the server involved marking executable segments with angle brackets and percent signs like this:

1. 2. 3. 4.

You tell Windows that you want your thread to issue low-priority I/O requests by calling ThreadIO s BeginBackgroundProcessing method . Note that this also lowers the CPU scheduling priority of the thread . You can return the thread to making normal-priority I/O requests (and normal CPU scheduling priority) by calling EndBackgroundProcessing or by calling Dispose on the value returned by BeginBackgroundProcessing (as shown above via C# s using statement) . A thread can only affect its own background processing mode; Windows doesn t allow a thread to change the background processing mode of another thread . If you want all threads in a process to make low-priority I/O requests and have low CPU scheduling, you can call BeginBackgroundProcessing, passing in true for the process parameter . A process can only affect its own background processing mode; Windows doesn t allow a thread to change the background processing mode of another process . Important As a developer, it is your responsibility to use these new background priorities to

ControlToValidate="Range" Display="Dynamic" Type="Integer" MinimumValue="1" MaximumValue="12" ErrorMessage="Out of Range" runat=server /> <ASP:RequiredFieldValidator ControlToValidate="Range" Display="Dynamic" ErrorMessage="Must enter a value." runat=server /> </td> </tr> <tr> <td> Regular Expression Validation (nnn-nn-nnnn): </td> <td> <input id="RegEx" type="text" runat=server size=11 /> </td> <td> <ASP:RegularExpressionValidator ID="ValRegEx" ControlToValidate="RegEx" runat="SERVER" Display="Dynamic" ErrorMessage= "Enter a valid U.S. SSN (nnn-nn-nnnn)."

This technique is the standard way to implement infinite loops and event loops. Faking an infinite loop with a statement like for i := 1 to 9999 is making a poor substitution because using loop limits muddies the intent of the loop maybe 9999 is a legitimate value. Such a fake infinite loop can also break down under maintenance.

sound right. You ll probably need to do a couple of rounds of testing and revising before you re satis ed with your results and are ready to move on to the next step. When you have written your three Key Point headlines, you have made sure that you will justify the Call to Action slide with the Key Point slides that follow it. Your Call to Action and Key Point headlines form the most important information at the top level of the hierarchy, as shown in Figure 5-13, which de nes the most important and meaningful information that you want your audience s working memory to engage and integrate into long-term memory.

wait time in seconds that processes waited on that wait type since the system was last restarted or the counters were cleared; the percentage of the wait time of this type out of the total; and the running percentage from the top-most wait type until the current one.
