Question

vb中如何根据关键字读取txt 中包含关键字的那一行

比如说一个txt中有这样的内容：

hj2_ghg.exe>|1/2|136408065|21:57 2007/October/09
yu212.exe>|2/2|276728958|17:18 2009/January/25

比如当我在一个文本框中输入yu212.exe 就能把

yu212.exe>|2/2|276728958|17:18 2009/January/25

这一行都读出来？

Option Explicit
Dim arr
Private Sub Command1_Click()
Dim i As Long
For i = 0 To UBound(arr)
If InStr(arr(i), Text1) = 1 Then '查到就退出，可以装入数组
MsgBox arr(i)
Exit For
End If
Next
If i = UBound(arr) + 1 Then MsgBox "未查到：" & Text1
End Sub
Private Sub Form_Load()
If Dir("c:\1.txt") <> "" Then
Open "c:\1.txt" For Input As #1
arr = Split(StrConv(InputB(LOF(1), 1), vbUnicode), vbNewLine)
Close #1
Else
MsgBox "为找到文件：" & "c:\1.txt"
Unload Me
End If
Text1 = "yu212.exe"
End Sub
