PasteSpecial Range类失败，我能做得更好吗？

我正在尝试从一本书中复制一个范围，打开目标书并将值附加到该工作表，使Range类失败并且不确定如何解决这个问题。这是我的代码，感谢您的关注。

Sub openDATfiles()

' openDATfiles Macro

Dim ws As Worksheet, strFile As String, x As Integer, _
y As Long, Pressure As Variant, Tstamp As Variant, LastRow As Long, LastRow2 As Long, cn As Variant, fPath As String

fPath = "F:\McMAHON\From David\SJ15_10_01_CD\"
strFile = fPath & Dir(fPath & "*.dat")
x = 1
y = 1

' Start Loop 1

Do While Len(strFile) > 0

Workbooks.OpenText FileName:= _
    strFile, Origin:=437, StartRow _
    :=1, DataType:=xlDelimited, TextQualifier:=xlDoubleQuote, _
    ConsecutiveDelimiter:=False, Tab:=False, Semicolon:=False, Comma:=True _
    , Space:=False, Other:=False, FieldInfo:=Array(Array(1, 1), Array(2, 1), _
    Array(3, 1), Array(4, 1), Array(5, 1), Array(6, 1), Array(7, 1), Array(8, 1), Array(9, 1), _
    Array(10, 1), Array(11, 1)), TrailingMinusNumbers:=True

Set ws = ActiveSheet


   Do Until x = 31

    Pressure = WorksheetFunction.Max(Range("J" & y + 4 & ":J" & y + 1203))
    Tstamp = WorksheetFunction.Max(Range("A" & y + 4 & ":A" & y + 1203))

        x = x + 1
        y = y + 1201

        LastRow = ws.Range("N" & Rows.Count).End(xlUp).Row + 1

    ws.Range("O" & LastRow).Value = Pressure
    ws.Range("N" & LastRow).Value = Tstamp



Loop

     strFile = fPath & Dir

Range("A1:K36004").delete Shift:=xlUp

Range("N2:O31").Copy

ActiveWorkbook.Close savechanges:=False




Dim Pastebook As Workbook

'## Open both workbooks first:
Set Pastebook = Workbooks.Open("F:\McMAHON\Useful Things\VBA\PiezoData")

LastRow2 = ActiveWorkbook.Worksheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row + 1

'Now, paste to y worksheet:
Pastebook.Sheets("sheet1").Range("A" & LastRow2).PasteSpecial xlPasteValues


Loop

End Sub

非常感谢任何提示或帮助，谢谢。

正如@ Mat'sMug所提到的那样，你过早地关闭了你复制的文件，导致了上述错误。

而且 更大的问题是 Len(strFile) > 0 因为您已经分配了文件夹的路径 strFile，所以它永远不会是0，你将永远陷入你的循环中。

以下是您的代码已更正和改进：
