When the program starts, as shown in Figure 11-6, you can type an address into the URL bar to visit a web site. If you wish to add a site to your bookmarks list, click Bookmarks Bookmark This Page. Alternatively, you can press Ctrl+D. Searching is very easy within Firefox, using its search bar at the top right of the window. By default, Firefox uses Google for searches. To choose from other search engines, click the small down arrow on the left side of the search box. You can even enter your own choice of site if your favorite isn t already in the list click Manage Search Engines, and then click the Get More Search Engines link in the dialog box that appears. Firefox popularized the principle of tabbed browsing, which means you can have more than one site open at once. To open a new tab, press Ctrl+T. You can move between the tabs by clicking them.

As you can imagine, if you can handle requests, you can also handle responses. This is done using the Response object, which can be used to write new output to the response buffer or to redirect the user to another page or site.

There is an enormous difference between hacking the data dictionary with a published, documented PL/SQL API, and hacking the data dictionary with statements like update col$ set .... In the former case, you may not understand what you are telling Oracle about your system, but at least you will be leaving the data dictionary in a self-consistent state. In the latter case, (a) you don t know how many other changes you should have made at the same time, and (b) you don t know if all your changes will actually arrive at the data dictionary, as it seems to get refreshed from the dictionary cache (v$rowcache) in a fairly random way, so (c) you can very easily leave your database in an inconsistent state that will lead to subsequence security breaches, crashes, and silent yet extensive data corruption.

Figure 5-53. Setting up a hierarchical relationship In Figure 5-53, a parent/child relationship is established between AccountID and AccountGeneralID. This relationship is formed as a group with the default name table1_Details_Group. We will make use of this group later to format the report output to show the account name hierarchy. As you can see in the report output, depending on the hierarchy level, the account name shifts to the left. You ll also notice that all accounts that are of the General type appear in a bold font. Both of these settings are easy to apply. Let s first take care of the bold font for all the General accounts. Please make sure to have the following expression set for the FontWeight property of TableRow2 Column2: Normal, Arial, 8pt, =iif(Fields!AccountType.Value = "1", "Bold", "Normal") Now, let s take care of the hierarchical display of account names. Recall that, depending on the hierarchy, the account name leaves some space to its left side. We can achieve this by setting up the Padding(Left) property with the following expression: =Level("table1_Details_Group") * 10 & "pt", 2pt, 2pt, 2pt As you can see here, we make use of the Level() function to find out the group level and multiply it by 10 pixels. Therefore, as the group level increases, so does the space on the left side of the account name, making the display look truly hierarchical. Figure 5-54 shows the Properties window with FontWeight and Padding set up.
