Difference between ‘on error goto 0’ and ‘on error goto -1’ — VBA

by

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
