上面是VBS脚本程序，下面是我改的VB程序，调试时，老出错，请大家指点帮忙。谢谢

Dim fso, f1, f2, f3, f4, regex, arr
Dim str, num1, num2, num3, fn1, fn2, fn3, fn4, fn5, fn6

Private Sub Command1_Click()
CommonDialog1.Filter = "LOC文件(*.loc)|*.loc|所有文件(*.*)|*.*"
CommonDialog1.ShowOpen
fn1 = CommonDialog1.FileName
Text1.Text = fn1
''读取数据源文件用fn1文件
End Sub

Private Sub Command2_Click()
CommonDialog1.Filter = "CSV文件(*.csv)|*.csv|文本文件(*.txt)|txt|所有文件(*.*)|*.*"
CommonDialog1.ShowSave
fn6 = CommonDialog1.FileName
Text2.Text = fn6
''输出数据文件fn6文件
End Sub

Private Sub Command3_Click()
Set fso = CreateObject("scripting.filesystemobject")
Set f6 = fso.createtextfile(fn2, True)
f6.writeline "Log,Distance,4Hz,4Hz,,Depth"
f6.writeline "#,(m),(mA), (dBmA),,(cm)"
Set f1 = fso.opentextfile(fn1, 1)
Do While f1.atendofstream <> True
str = f1.readline
If regex.Test(str) Then
arr = Split(str, ",")
If arr(4) > 0 Then
num1 = arr(4) * 1000
num2 = Log(num1) / Log(10) * 20
num3 = arr(2) * 100
f6.writeline arr(1)&","&","&num1&","&round(num2,2)&","&num3&","
End If
End If

End Sub

Private Sub exitfile_Click()
Unload Me

Private Sub Form_Load()

End Sub

Private Sub Option1_Click()

这是我写的VB程序，请大家帮忙看看哪里不对！！！

楼主有没有先引用Microsoft VBScript Regular Expressions？

如果没有的话。正则表达式是不能用set reg=new regexp这样创建的。

可以这样，set reg =createobject("vbscript.regexp")

谢谢你的帮助，我引用了Microsoft VBScript Regular Expressions 5.5，并且按你所说的改了，但还是不行。！！！

首先，创建模块
然后，SubMain自己处理
引用正则表达式库
没其他太多需要注意的。
