When a Stop error occurs, Windows XP Professional displays a Stop message and writes diagnostic information to a memory dump file. When you restart your system by using Normal mode or Safe mode (with networking) and log on to Windows XP Professional, the Error Reporting service gathers information about the problem and displays a dialog box that gives you the option of sending a report to Microsoft. For more information about Error Reporting, click Tools in Help and Support Center. For more information about Stop Messages, memory dump files, and using Error Reporting to get information about kernel-mode errors, see Common Stop Messages for Troubleshooting on the companion CD.

Event Query (Eventquery.vbs) is a command-line tool that you can use to search the event logs by using specified criteria. For troubleshooting, using Event Query enables you to view the event logs for entries related to specified event properties, including date and time, event ID, and user name. Event Query also enables you to save output to a file and to specify the file format to use. For example, you can save output to a .csv file and further analyze the data by using Microsoft Excel. For more information about Event Query and the event logs, click Tools in Help and Support Center.

Event Triggers (Eventtriggers.exe) is a command-line tool that you can use to view, set, or delete trigger events. You can specify an error-log trigger condition to monitor and the task to run, including starting other programs, if thresholds are exceeded. For example, you can create a trigger that starts Disk Cleanup (Cleanmgr.exe) when a Low Disk Space message is recorded to the System log. For more information about Event Triggers and the event logs, click Tools in Help and Support Center.

You have now reached the last chapter of the book and have learned quite a few new concepts along the way. In this chapter, you ll dot the i s and cross the t s by developing a fully functional weather-tracking application. You will be working with new processes in this chapter, but you will also draw on what you ve learned in previous chapters to create the final product. In this chapter, you will put everything you ve learned together to create this one application.

Event Viewer (Eventvwr.msc) maintains application, security, and system logs for your computer. It also contains useful information for diagnosing hardware and software problems. Event Viewer provides three logs. Application Log Contains events logged by applications or programs. For example, a database program might record read or write errors to this log. Security Log Holds security event records, such as logon attempts and actions related to creating, opening, or deleting files. An administrator can view information or specify events to record in the security log. System Log Contains information about system components. For example, an entry is made when a driver or other system component fails to load during startup. For more information about how to insert custom shutdown information into the System log, see Shutdown Event Tracker later in this appendix. You can save Event Viewer logs and specify filtering criteria for viewing information. Event Viewer logs can provide clues to problems that affect the system. When troubleshooting, use the information to identify problems with applications, drivers, or services, and to identify frequently occurring issues. To start Event Viewer 1. In the Run dialog box, type eventvwr.msc. or 2. Start Event Viewer from the Computer Management snap-in. For more information about the Computer Management MMC snap-in, see Computer Management Tool later in this appendix. For more information about using Event Viewer, see Help on the Action menu in Event Viewer.

Global Flags Editor (Gflags.exe) is a GUI-mode Support Tool that allows members of the Administrators group to enable and disable advanced internal system diagnostics and troubleshooting features on computers running Windows XP Professional. Gflags.exe is designed as a debugging tool for application developers. It is most often used to turn on indicators that other tools track, count, and log. Use it to edit the global flag settings that the kernel uses when starting. The term global flag refers to the GlobalFlag registry entries that Windows XP Professional checks to enable or disable advanced internal system diagnostics and troubleshooting tests.
