找出文件01.txt文件中，以#BZ开头的文字（如“#BZ三”、“#BZ溙”等，#BZ后是任意汉字）。
统计这个文件中有多少不同类型（不重复）的#BZ开头文字，并把结果保存到当前目录的“结果.txt”。

提示：xml文件可以作为文本文件打开查找，“结果.txt”是如下形式：
#BZ三
#BZ溙
.
.
.
#BZ犃
共83个

好像不是特别难哦，假设01.txt在d盘根目录下，结果也存储到d盘根目录，新建一工程，窗体里放一个命令按钮，拷贝下述代码，运行后点击按钮即可完成任务。
Private Sub Command1_Click()
  Dim i As Integer, j As Integer, f As Long, a As String, b As String, d As String
  f = FreeFile
  Open "d:\01.txt" For Input As f
  b = ""
  While Not EOF(f)
    Line Input #f, a
    b = b & a
  Wend
  Close #f
  j = 1: d = "": f = 0
  Do
    i = InStr(j, b, "#BZ")
    j = i + 3
    If j < Len(b) And j > 3 Then
      a = Mid(b, j, 1)
      If InStr(d, a) = 0 Then d = d & "#BZ" & a & vbCrLf: f = f + 1
    End If
  Loop Until i = 0
  d = d & "共" & f & "个"
  f = FreeFile
  Open "d:\结果.txt" For Output As f
  Print #f, d
  Close #f
End Sub

谢谢啦

好久没有用VB了 现在都忘记了，这个应该是do while   loop循环？
我这样应该是不对的 ，
通过open读取txt，一行行读取，寻找关键字符 （text2.text），提取关键字符 #BZ 后的汉子（主要判断是双字节就提取，排除标点比较麻烦），然后输出
