VBS向文本文件添加不带空格的行
试图弄清楚如何修改下面的代码以添加到文件末尾恰好有额外 CRLF 的文本文件。根据我放置 CHR(10) 的位置，我会得到令人困惑的结果。有什么想法如何去除 CRLF 或删除空行吗？我需要最终没有多余的 CRLF ！
'如果 RandomCSV 文件不是 20 的倍数，此脚本将向该文件添加行。 '如果文件已经是 20 的倍数，则不会发生任何事情。
dim filesys, readfile, contents, lines, remainder, LinesToAdd, StaticLine, Appendfile, Count
dim field1, field2, field3, field4
set filesys = CreateObject("Scripting.FileSystemObject")
Set readfile = filesys.OpenTextFile("C:\RandomCSV.txt", 1, false)
contents = readfile.ReadAll
Lines = readfile.line
readfile.close
MsgBox "The file contains this many lines " & Lines
remainder = lines mod 20
LinesToAdd = (20 - remainder)
MsgBox "Adding this many lines " & LinesToAdd
If LinesToAdd <> 20 then
Set Appendfile = filesys.OpenTextFile("C:\RandomCSV.txt", 8, false)
For Count = 1 to LinesToAdd
Appendfile.write Chr(34) & "Field1" & Chr(34) & Chr(44) & Chr(34) & "Field2" & Chr(34) & Chr(44) & Chr(34) & "Field3" & Chr(34) & Chr(44) & Chr(34) & "Field4" & Chr(10)
Next
appendfile.close
End If
trying to figure out how to modify the code below to add to a text file that happens to have an extra CRLF at the end of the file. I get confusing results depending on where I put the CHR(10). Any ideas how to strip the CRLF or remove the blank line? I need to end up with no extra CRLF's !!!
'This script will add lines to the RandomCSV file if it is not in a multiple of 20.
'If the file is already a mulitiple of 20, nothing should happen.
dim filesys, readfile, contents, lines, remainder, LinesToAdd, StaticLine, Appendfile, Count
dim field1, field2, field3, field4
set filesys = CreateObject("Scripting.FileSystemObject")
Set readfile = filesys.OpenTextFile("C:\RandomCSV.txt", 1, false)
contents = readfile.ReadAll
Lines = readfile.line
readfile.close
MsgBox "The file contains this many lines " & Lines
remainder = lines mod 20
LinesToAdd = (20 - remainder)
MsgBox "Adding this many lines " & LinesToAdd
If LinesToAdd <> 20 then
Set Appendfile = filesys.OpenTextFile("C:\RandomCSV.txt", 8, false)
For Count = 1 to LinesToAdd
Appendfile.write Chr(34) & "Field1" & Chr(34) & Chr(44) & Chr(34) & "Field2" & Chr(34) & Chr(44) & Chr(34) & "Field3" & Chr(34) & Chr(44) & Chr(34) & "Field4" & Chr(10)
Next
appendfile.close
End If

这就是我最终删除文件末尾的 CRLF 的方法。似乎工作正常：
'==============================
'去掉文件末尾的空行
Dim strEnd
Const ForReading = 1
'Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
设置 objFile = objFSO.OpenTextFile("C:\RandomCSV.txt", ForReading)
strFile = objFile.ReadAll
objFile.Close
intLength = Len(strFile)
strEnd = Right(strFile, 2)
如果 strEnd = vbCrLf 则
strFile = Left(strFile, intLength - 2)
设置 objFile = objFSO.OpenTextFile("C:randomCSV.txt", ForWriting)
objFile.Write strFile
objFile.关闭
结束如果
字符串文件=“”
Here's what I ended up doing to get rid of the CRLF at the end of the file. Seems to work fine:
'============================
'Get rid of blank Line at End of file
Dim strEnd
Const ForReading = 1
'Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\RandomCSV.txt", ForReading)
strFile = objFile.ReadAll
objFile.Close
intLength = Len(strFile)
strEnd = Right(strFile, 2)
If strEnd = vbCrLf Then
strFile = Left(strFile, intLength - 2)
Set objFile = objFSO.OpenTextFile("C:randomCSV.txt", ForWriting)
objFile.Write strFile
objFile.Close
End If
strFile = ""
