这是一个很有实际学习意义的VB操作文本文件的一个实例，学习VB的朋友一定要认真的看一看。
\'功能：删除、替换文本中一行，或者插入内容到文本中某一行
\'作者: soho_andy (冰)
\'参数：
\'strSourceFile 原始文件完整名
\'strTargetFile 生成新文件的完整名
\'intRow 操作的行数
Sub 操作文件中一行(strSourceFile As String, strTargetFile As String, intRow As Long)
Dim filenum As Integer
Dim fileContents As String
Dim fileInfo() As String
Dim i As Integer
Dim j As Integer
filenum = FreeFile
Open strSourceFile For Binary As #filenum
fileContents = Space(LOF(filenum))
Get #filenum, , fileContents
Close filenum
fileInfo = Split(fileContents, vbCrLf)
\'取出源文件行数，按照回车换行来分隔成数组
filenum = FreeFile
If Dir(strTargetFile, vbNormal) <> \"\" Then
Kill strTargetFile
End If
Dim Filestr() As String
\'删除一行代码块
Open strTargetFile For Append As #filenum
\'循环每一行
For i = 0 To UBound(fileInfo) - 1
If i <> intRow - 1 Then
Print #filenum, fileInfo(i)
End If
Next
Close #filenum
\'替换一行代码块
Open strTargetFile For Append As #filenum
\'循环每一行
For i = 0 To UBound(fileInfo) - 1
If i = intRow - 1 Then
Print #filenum, \"你要替换进去的内容\"
End If Next
Close #filenum
\'插入一行代码块
Open strTargetFile For Append As #filenum
\'循环每一行
For i = 0 To UBound(fileInfo) - 1
If i = intRow - 1 Then
Print #filenum, \"你要插入到这行的内容\"
Print #filenum, fileInfo(i) \'保留原来的行，位置后移一位
End If
Next
Close #filenum
MsgBox \"完毕\"
End Sub
