# On Error GoTo ... Resume Statement

Umožňuje spracovanie chýb potom, ako sa vyskytla chyba alebo obnovuje vykonávanie.

## Syntax:

    On [Local] Error {GoTo Labelname | GoTo 0 | Resume Next}

## Paremetre:

GoTo Labelname: Ak sa vyskytne chyba, umožní spracovanie chyby, ktoré začína na riadku "Labelname".

Resume Next: Ak sa vyskytne chyba, vykonávanie programu pokračuje príkazom, ktorý nasleduje po príkaze na ktorom sa vyskytla.

GoTo 0: Disables the error handler in the current procedure.

Local: "On error" is global in scope, and remains active until canceled by another "On error" statement. "On Local error" is local to the routine which invokes it. Local error handling overrides any previous global setting. When the invoking routine exits, the local error handling is canceled automatically, and any previous global setting is restored.

The On Error GoTo statement is used to react to errors that occur in a macro.

## Príklad:

    Sub ExampleReset
    On Error GoTo ErrorHandler
    Dim iNumber As Integer
    Dim iCount As Integer
    Dim sLine As String
    Dim aFile As String
        aFile = "c:\data.txt"
        iNumber = Freefile
        Open aFile For Output As #iNumber
        Print #iNumber, "Toto je riadok textu."
        Close #iNumber
        iNumber = Freefile
        Open aFile For Input As iNumber
        For iCount = 1 To 5
            Line Input #iNumber, sLine
            If sLine <>"" Then
                Rem
            End If
        Next iCount
        Close #iNumber
        Exit Sub
    ErrorHandler:
        Reset
        MsgBox "All files will be closed",0,"Error"
    End Sub
