The Err objects Number property returns a decimal integer, but the WMI SDK generally uses hexadecimal values, so these scripts take a bilingual approach. For each error check, the script creates a custom error message and assigns it to strMessage. Top of page, handling Errors with VBScript, this column being part of the "Doctor Scripto's Script Shop" series, we're going to go out on a limb and assume you've already read the Windows 2000 Scripting Guide sections on error handling, or at least have some. The script in Listing 8 pings a remote machine with Win32_PingStatus and reports whether the ping was successful. Even if the script finds the classes, methods and properties it's seeking, it's still not home free. We check for an error after trying to bind to WMI on the machine specified in strComputer. Or what if the error source and description returned by VBScript arent very helpful in debugging? Also with vars you can dim vars in an array: dim iRule(3) but that would turn out like this: (because 0 is included) iRule(0 var1" iRule(1 var2" iRule(2 var3" iRule(3 var4 using vars in the script.
The default timeout is 1000 milliseconds, considerably faster than the WMI binding approach in most cases. If this is true and the collection of processes has 0 members, this means that no processes with this name were found, so there's no point in trying to terminate them. The custom message displayed at the beginning of the data for each helps communicate exactly what the problem was. After calling ExecQuery to request any instance of Win32_Process whose Name property is the value of strTargetProc, the script checks whether unt. Dim iRule now you would have a variable call iRule now you can start to add things to you vars. The message is passed as a parameter to the DisplayCustomError subroutine, which displays this message along with the data from the Err object. Retrieves properties or calls methods that may not be available on that version of the operating system. WMI and adsi errors use larger numbers, generally 8-digit hex numbers. For example, if the script is expecting a WMI datetime value and the property in question returns a null value, the script may grind gears unless you handle that possibility.
