循环错误通过目录

Question

我希望有人能帮忙...我有下面的代码，整天绝对有效。 直到16:10为止，现在突然决定接收运行时错误。 在Sheet1.Cells(lastRow, 1) = Data

Sub Loopthroughtxtdir()
    Dim Filename As String
    Dim Path As String

    Path = "C:\MK\MasterData\"
    Filename = Dir(Path & "*.txt")

    With ThisWorkbook.Sheets("Sheet1")
        Dim lastRow As Long
        lastRow = Sheet1.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
        Do While Len(Filename) > 0
            Dim handle As Integer
            handle = FreeFile
            Open Path & Filename For Input As #handle
            Do Until EOF(handle)
                Line Input #handle, Data
                Sheet1.Cells(lastRow, 1) = Data
                lastRow = lastRow + 1
            Loop
            Close #handle
            Filename = Dir
        Loop
    End With

    MsgBox ("Import Complete")

End Sub

谁能帮忙。 我很困惑为什么这行得通。 一切都没有改变，现在经过几次测试已停止。

正如评论中指出的那样，您的行已用完。 一种解决方案是进行测试，看看您是否刚打完最后一行，然后继续使用新的工作表（显然未经测试，但应有主旨）：

Sub Loopthroughtxtdir()
    Dim Filename As String
    Dim Path As String

    Path = "C:\MK\MasterData\"
    Filename = Dir$(Path & "*.txt")

    Dim currentSheet As Worksheet
    Set currentSheet = ThisWorkbook.Worksheets("Sheet1")
    With currentSheet
        Dim lastRow As Long
        lastRow = .Cells(.Rows.Count, 1).End(xlUp).Offset(1, 0).Row
    End With

    Do While Len(Filename) > 0
        Dim handle As Integer
        handle = FreeFile
        Open Path & Filename For Input As #handle
        Do Until EOF(handle)
            Line Input #handle, Data
            currentSheet.Cells(lastRow, 1) = Data
            lastRow = lastRow + 1
            If lastRow > currentSheet.Rows.Count Then
                Set currentSheet = ThisWorkbook.Worksheets.Add
                lastRow = 1
            End If
        Loop
        Close #handle
        Filename = Dir$
    Loop

    MsgBox ("Import Complete")
End Sub
