    Dim Bol As Boolean

    For i = 1 To Len(Srg)

        s = Mid(Srg, i, 1)

        If n = 1 Then

            Bol = Asc(s) < 0    '文字

            Bol = s Like "[a-z,A-Z]"    '字母

        ElseIf n = 0 Then

            Bol = s Like "#"    '数字

        End If

        If Bol Then MyString = MyString & s
