If you want to add a quick total to the data, scroll to the bottom of a column and click the AutoCalc button. Select the type of total you want from the list that opens. The web part inserts a new totals row at the bottom of the datasheet. To remove a field from the display, click and drag the field header off the datasheet. When the pointer includes a red X, drop it. To add fields back to the display, click the Field List button to add fields to the display. Drag the fields you want to see into the datasheet (the web part places the fields into the Column Area).

Moreover, the EVALUATION value must be an integer between 1 and 5, or a null value. Any data manipulation command against the REG_VIEW view that violates one of the above three checks will result in an Oracle error message. CHECK OPTION constraints show up in the data dictionary with a CONSTRAINT_TYPE value V; notice the system generated constraint name for the REG_VIEW view.

Here Mark used a motif a recurring visual or verbal theme in the form of a murder mystery to make the story coherent and memorable. First of all, I m going to show you a motive. The word motive appeared on the screen (top) along with a picture of a stack of money. I m going to show you the means, he said, as the word means and an image of pills similar to this one appeared on the screen (middle). I m going to show you the death, he said, as the word death and the familiar outline of Bob appeared next to Carol on the screen (bottom). With these slides, Mark asked the jurors to follow the simple formula that underlies every murder-mystery story: motive + means = death. Even jurors who don t watch TV would

The next step is to add code that declares an event to the user control s class. You then add code that handles the Button click event. Inside the click event, you raise your event back to the consuming page. The page that uses your user control can then trap the event and respond accordingly. The following shows an example of both the event declaration and the Button click event.

The conditional formatting feature is a little more complicated in Excel 2007 . This feature has been significantly enhanced compared with earlier versions, with which you could only define three formatting variants for each cell (which was usually sufficient) . Only time (and practice) will tell whether the variety of options now available will actually help improve the quality of information that can be conveyed . This most definitely won't be the case if the designer of a chart solution gets completely carried away and adopts the attitude If it can be done, why not do it The result then will be psychedelic tables that confuse users rather than help them digest new information . Important Human perception is severely limited when it comes to interpreting small or nonpictorial symbols . If you plan to generate more than three different signals (of any kind) in one cell range in order to convey certain information to the user, you should have a very good reason for doing so .

Part II:

The method requires you to pass a WizardStep object, which can be problematic. However, the method is a simple wrapper around the setter of the ActiveStepIndex property. If you want to jump to a particular step and not hold an instance of the corresponding WizardStep object, setting ActiveStepIndex is just as effective. Table 8-4 lists the key events in the life of a Wizard control in an ASP.NET 2.0 page.

Where Does the Web.config File Go One of the frustrations for ASP programmers is the odd patchwork of files that grows up around any complex Web site. With ASP, the only configuration file was Global.asa, and in fact, this file is similar to the ASP.NET Global.asax file. ASP beginners often ask, Where do I put the Global.asa file It turns out that in practice you had to put a Global.asa file in almost every directory. In ASP.NET, the Web.config file provides a mechanism that should allow many sites to have far fewer redundant configuration settings within each virtual site. There is a root configuration file, in the same format as the Web.config files, named Machine.config. This file is included with the .NET Framework and contains many default settings. It is located under the Windows root, in the %windir%\Microsoft.NET\Framework\<version>\CONFIG folder. All other directories on the site inherit settings from this root file and from all Web.config files that exist higher in the logical hierarchy. For example, one possible elementsection in the Web.config file is appSettings. This section is normally used to make certain variables available to all pages within an application, to multiple applications (if the variable exists in a virtual directory with other applications located logically under it), or even to all applications on the machine (if the appSettings section is located in the Machine.config file). Individual appSettings values can be overridden based on the location of the Web.config file in the hierarchy. Suppose, for example, that Machine.config contains the following section (within the <configuration></configuration> tags): <appSettings>

class SomeType { void SomeMethod() { // Open a file. using (FileStream fs = new FileStream(@"C:\ReadMe.txt", FileMode.Open)) { // Display 100 divided by the first byte in the file. Console.WriteLine(100 / fs.ReadByte()); } } }

// VERY IMPORTANT NOTE: // The constructor for this class takes a reference to a UiPublication. // The UiPublication object MUST NOT BE DESTROYED before the DatabasePublication // object. If it is, the DatabasePublication object will cause the program to

has been corrupted and cannot be restored . Allowing the application to continue running might result in unpredictable behavior or security vulnerabilities . When this situation is detected, that method should not throw an exception; instead, it should force the process to terminate immediately by calling System.Environment s FailFast method .
