程序代码如下：

Private Sub Command1_Click()

Dim Sname As String, Skey As String    ‘Sname 保存姓名，Skey保存关键字

Dim i As Integer, j As Integer, n As Integer   ‘n关键字的长度

Skey = Text1.Text

n = Len(Skey)

List2.Clear

For i = 1 To List1.ListCount     ‘ListCount是列表框中项目的个数

    Sname = List1.List(i - 1)     ‘将List1中的第i-1项赋值给Sname

    For j = 1 To     ①   

    If Skey =     ②       Then

        List2.AddItem Sname

        Exit For

    End If

    Next j

Next i

If      ③     = 0 Then List2.AddItem "没有找到带<" & Skey & ">的名字。"

End Sub
