On Error Goto 0 Vb6
the “on error goto 0” and “error resume next” in old ASP mean? up vote 5 down vote favorite I am working with old ASP code and I am not sure about semantics of on error goto 0 and error resume next construction. Can you recommend me some useful resources or enlight me directly? asp-classic vbscript share|improve this question edited Dec 1 '11 at on error resume next vbscript 20:02 Joel Coehoorn 249k92440662 asked May 13 '09 at 8:12 Jakub Šturc 17.9k196996 add a comment| 5 Answers 5 active oldest votes up vote 4 down vote accepted On error resume next: If there is an exception in the program, just ignore it and continue to the next statement. Considered very bad and ugly, and rightly so in my opinion. It's like having a big: try { // your code } catch { // nothing! muhaha } in every method of your code (or worse, around the whole program). On error goto 0: disables any error handler that is defined in the current procedure. It's like having a big try-catch around your code, which gets disabled as soon as its hit this line. For more information, see the MSDN. share|improve this answer edited May 13 '09 at 8:32 answered May 13 '09 at 8:20 Razzie 19.7k104862 2 +1 Yes. I just discovered this: If you use On Error Goto 0 then every other On Error statement in the procedure becomes disabled. That was totally unexpected. I thought that the documentation was saying that only the last executed error handle

I've tried google and msdn, but I've had no luck. excel vba msdn share|improve this question asked Jan 4 '13 at 14:22 sterlingalston 155116 This documentation is for Visual Basic, not VBA, but the concepts are similar enough in this case http://stackoverflow.com/questions/14158901/difference-between-on-error-goto-0-and-on-error-goto-1-vba that it should explain the difference. –vcsjones Jan 4 '13 at 14:30 add a comment| 4 Answers 4 active oldest votes up vote 33 down vote accepted On Error GoTo 0 disables any error trapping currently present in the procedure. On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled. Sub OnErrorGotoZeroTest() On Error GoTo 0 Err.Raise Number:=9999, Description:="Forced Error" End Sub share|improve this answer edited Mar 22 '13 at 10:08 answered Jan 4 '13 at 15:29 Francis Dean 1,42611118 1 +1, good explanation.

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 errors that occur.Within any particular procedure, an error is not necessarily fatal as long
