Operators Index Colophon Error Handling Error handling does not involve finding errors in your scripts. Instead, use error handling techniques to allow your program to continue executing even though a potentially fatal error has occurred. Ordinarily, vbscript error handling line number all runtime errors that are generated by the VBScript engine are fatal, since execution of the current script is halted when the error occurs. Error handling allows you to inform the user of the problem and either halt execution of the program or, if it is prudent, continue executing the program.The On Error Resume Next StatementThere are two main elements to error handling in VBScript. The first is the On Error statement, which informs the VBScript engine of your intention to handle errors yourself, rather than to allow the VBScript engine to display a typically uninformative error message and halt the program. This is done by inserting a statement like the following at the start of a procedure:On Error Resume NextThis tells the VBScript engine that, should an error occur, you want it to continue executing the program starting with the line of code which directly follows the line in which the error occurred. For example, in the simple WSH script:On Error Resume Next x = 10 y = 0 z =

Lowe-Norris | Windows IT Pro EMAIL Tweet Comments 3 Advertisement Downloads 20500.zip Windows Script Host This month, I concentrate on a subject that often doesn't http://windowsitpro.com/scripting/scripting-solutions-wsh-and-com-trapping-and-handling-errors-your-scripts receive generic coverage: how you can trap and handle errors in VBScript code that you write for the Windows Script Host (WSH) environment. I discuss three practical ways you can trap and handle errors: explicitly declaring variables, basic error handling with the CheckError subprocedure, and advanced error handling with customized CheckError subprocedures. Explicitly Declaring Variables In VBScript, you don't have to explicitly declare the variables that you use. However, explicitly declaring variables is good practice. To make sure that you explicitly declare variables, you can use the Option Explicit command at the beginning of your script. Option Explicit forces the VBScript interpreter (in this case, WSH) to make sure that you use an explicit declaration (i.e., a Dim, Public, or Private statement) to declare a variable before you use it. If you explicitly declare variables and use Option Explicit, you'll spend less time debugging scripts because you'll immediately catch such errors as misspelled variable names and mismatched variables. If your script has many variables and you put each explicit declaration on a separate line,

It wasn't very helpful :P I believe what you are looking for is the ReferenceError's stack property. You can access it with the argument that you pass to the catch: try { someUndefinedFunction("test"); } catch(e) { console.log(e.stack) } example output: ReferenceError: someUndefinedFunction is not defined at message (http://example.com/example.html:4:3) at
