On Error Statement Enables or disables error-handling.Syntax Copy On Error Resume Next On Error GoTo 0 RemarksIf you don't use an On Error Resume Next statement anywhere in your code, any run-time error that occurs can cause an error message to be displayed and code execution stopped. However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other cases, there may be no apparent indication that any error occurred because the host does not need to notify the user. Again, this is purely a function of how the host handles any e

This documentation is archived and is not being maintained. Handling Errors in VBScript There is little difference between the methods used in Visual Basic and those used with VBScript. The primary difference is that VBScript does not support the concept of error handling by continuing https://msdn.microsoft.com/en-us/library/ms675540(v=vs.85).aspx execution at a label. In other words, you cannot use On Error GoTo in VBScript. Instead, use On Error Resume Next and then check both Err.Number and the Count property of the Errors collection, as shown in the following example: Copy

VBScript on error Constants C. 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, 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 vbscript on error 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 = x / y Alert za “Cannot divide by Zero” error is generated on the fourth line of code because the value of y is 0. But because you’ve placed the On Error statement in line 1, program execution continues with line 5. The problem with this is that when an error is generated, the user is unaware of it

So users see any error message that comes across... Instead, I would like my code to be able to catch any potential error and then fire off an email before redirecting the user to a more friendly error-page. This website is rather large, and every webpage comes with the same include file at the beginning... So ideally, I would like to set an error handler from the beginning of this include file. I haven't had any luck finding a way to do this without having to go through every page individually having error handling happen at the end of the script... Is there a possible way to code something like this from the include file?: ' Include file contents: Function MyHandler() 'Code for triggering email goes here response.redirect "ErrorPage.asp" End Function On Error call MyHandler() Thanks in advance! vbscript asp-classic error-handling share|improve this question asked May 14 '14 at 19:35 justanotherguy 10218 The above code doesn't actually work... It's just a sample to show the basic idea of what I'm looking for. And I do fix errors as soon as I get word of them... but this would streamline that proccess. But seriously... With 2,500+ pages of code, and 40 hours a week of new developement and changes, there are always going to be at least a couple errors that slip through. –justanotherguy May 14 '14 at 19:55 1 It's been a while since I used ASP. But I was thinking that the On Error Resume Next thing would be able to catch it. This SO answer might actually help: stackoverflow.com/questions/2202869/… –durbnpoisn May 14 '14 at 19:58 Thanks, but that's not quite what I'm asking for. That is a typical error handler, but what I'm asking for is not typical. I'm asking if it's possible to call a function (or a sub) as soon as the first error occurs. This way I could plug it into the website very easily. –justanotherguy May 14 '14 at 20:05
