保存路径不存在时的宏错误处理 [英] Macro error handling when save path doesnt exist

问题描述

我使用以下代码将备份版本保存到几个不同的外部备份位置以及原始文件中.有时尽管两个外部备份驱动器中的任何一个未连接，但都会产生错误.

I use the following code to save backup versions to a couple different external backup locations and to the original file. Sometime though either of the external backup drives is not connected and generates an error.

如何跳到下一行代码以执行其他两次保存?发生这种情况时，我还将添加一个消息框.

How can I skip to the next line of code to execute the other two saves? I will also be adding a message box when this happens.

Sub SaveToLocations()
' Saves active file to current plus two other backup locations, appends date and time in front of file name

    Dim datim As String
    datim = Format(CStr(Now), "yyyy_mm_dd_hh_mm_ss_")

    ActiveWorkbook.SaveCopyAs "I:\FBackupCS\" & datim & ActiveWorkbook.Name
    ActiveWorkbook.SaveCopyAs "E:\CS Docs\FBackupCS\" & datim & ActiveWorkbook.Name
    ActiveWorkbook.Save
End Sub

推荐答案

您可以使用以下功能

Function wkbSaveCopyAs(ByVal wkb As Workbook, ByVal fName As String) As Boolean

    On Error GoTo EH

    wkb.SaveCopyAs fName
    wkbSaveCopyAs = True

EH:

End Function

在这样的代码中

Sub SaveToLocations()
' Saves active file to current plus two other backup locations, appends date and time in front of file name

    Dim datim As String
    datim = Format(CStr(Now), "yyyy_mm_dd_hh_mm_ss_")

    'ActiveWorkbook.SaveCopyAs "I:\FBackupCS\" & datim & ActiveWorkbook.Name
    If Not wkbSaveCopyAs(ActiveWorkbook, "I:\FBackupCS\" & datim & ActiveWorkbook.Name) Then
        MsgBox "Ups, not saved", vbOKOnly
    End If

    'ActiveWorkbook.SaveCopyAs "E:\CS Docs\FBackupCS\" & datim & ActiveWorkbook.Name
    If Not wkbSaveCopyAs(ActiveWorkbook, "E:\CS Docs\FBackupCS\" & datim & ActiveWorkbook.Name) Then
        MsgBox "Ups, not saved", vbOKOnly
    End If

    ActiveWorkbook.Save
End Sub
