On Error Statement (Visual Basic) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 Visual Studio .NET 2003  Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. Without an On Error statement, any run-time error that occurs is fatal: an error message is displayed, and execution stops.Whenever possible, we suggest you use structured exception handling in your code, rather than using unstructured exception handling and the On Error statement.

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. It is interesting to point out that ONLY On Error Goto -1 will allow further error trapping within error trapping. Infact, even On Error Resume Next will still result in an untrapped error that halts operation. –Daniel Jan 4 '13 at 15:32 Thank you both so much, @Francis Dean and Daniel Cook.

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.
