Question

完全披露 - 这里不是程序员...... 我在这个网站上找到的代码取得了一些成功，可以很好地改变文本文件中的各个行。但我只需要在同一文本文件中更改文本字符串的最后一次出现。下面的代码会在文件中附加正确的更改，但这不是我需要它做的。我需要它彻底改变＆＃34; G00 Z.5＆＃34;到＆＃34; G00 Z7.0＆＃34;。以下是我到目前为止......

Sub TestMacro1()
    Dim sBuf As String
    Dim sTemp As String
    Dim iFileNum As Integer
    Dim sFileName As String
    Dim NewFileName As String
    Dim Pos As Long
    Dim Str As String

    Dim rplStr As String

    'Edit as needed
    sFileName = "Z:\Code-Unedited\TestText.txt"
    NewFileName = "Z:\Code-Edited\TestText.OUT"

    iFileNum = Freefile
    Open sFileName For Input As iFileNum

    Do Until EOF(iFileNum)
    Line Input #iFileNum, sBuf

    sTemp = sTemp & sBuf & vbCrLf

    Str = sBuf & vbCrLf

    Loop
    Close iFileNum


    sTemp = Replace(sTemp, "T01 01", "T2001")


    rplStr = StrReverse(Replace(StrReverse(Str), StrReverse("G00 Z.5"), StrReverse("G00 Z7.0"), , 1))


    'Save txt file as

    iFileNum = Freefile
    Open NewFileName For Output As iFileNum

    Print #iFileNum, sTemp
    Print #iFileNum, rplStr

    Close iFileNum
    End Sub

这是...之前的文本文件。

这是我的文本文件

N03 T01 01 M06  
G00 Z.5  
G00 Z.5

这是...之后的输出

这是我的文本文件

N03 T2001 M06  
G00 Z.5  
G00 Z.5  
G00 Z7.0

我需要最后一次出现＆＃34; G00 Z.5＆＃34;要更改为＆＃34; G00 Z7.0＆＃34;，但不附加正在创建的新文件。你能帮忙吗？

尝试一下：

Sub tgr()

    Dim oFSO As Object
    Dim sFilePath As String
    Dim sOldText As String
    Dim sNewText As String
    Dim sTemp As String
    Dim aAllFindReplace() As String
    Dim sLastFind As String, sLastReplace As String
    Dim aLines() As String
    Dim i As Long, j As Long
    Dim LastFound As Boolean

    sFilePath = Application.GetOpenFilename("Text Files,*.txt", , "Select Text File", , False)
    If sFilePath = "False" Then Exit Sub    'Pressed cancel

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    sOldText = oFSO.OpenTextFile(sFilePath).ReadAll
    aLines = Split(sOldText, vbCrLf)
    LastFound = False

    'Change as necessary
    ReDim aAllFindReplace(1 To 12, 1 To 2)
    For i = LBound(aAllFindReplace, 1) To UBound(aAllFindReplace, 1)
        aAllFindReplace(i, 1) = "T" & Format(i, "00") & " " & Format(i, "00")   'T01 01; T02 02; etc
        aAllFindReplace(i, 2) = "T2" & Format(i, "000")                         'T2001; T2002; etc
    Next i

    sLastFind = "G00 Z.5"
    sLastReplace = "G00 Z7.0"

    'Loop backwards to ensure last occurrence is found first
    For i = UBound(aLines) To LBound(aLines) Step -1
        sTemp = aLines(i)
        If Len(sTemp) > 0 Then
            'if you have any general replacements that need to happen, replace those here
            'replacements made here will occur for every instance
            For j = LBound(aAllFindReplace, 1) To UBound(aAllFindReplace, 1)
                sTemp = Replace(sTemp, aAllFindReplace(j, 1), aAllFindReplace(j, 2), Compare:=vbTextCompare)
            Next j

            If InStr(1, sTemp, sLastFind, vbTextCompare) > 0 And LastFound = False Then
                'If you have any replacements that should ONLY happen on the last occurrence, replace that here
                'Replacements made here will only happen on the last occurrence
                sTemp = Replace(sTemp, sLastFind, sLastReplace, Compare:=vbTextCompare)
                LastFound = True
            End If
            sNewText = sTemp & vbCrLf & sNewText
        End If
    Next i
    sNewText = Left(sNewText, Len(sNewText) - Len(vbCrLf))  'Remove ending newline

    'Output the file with the replacements in same location as a .OUT file
    With oFSO.CreateTextFile(Replace(sFilePath, ".txt", ".OUT", Compare:=vbTextCompare))
        .WriteLine sNewText
        .Close
    End With

    Set oFSO = Nothing
    Erase aLines

End Sub
