（加试题）小王要对字符串“welcome”进行重新排列，程序界面如图所示，则该程序执行后文本框 Text2 中显示的结果为（　　）

Private Sub Command2_Click()
　Dim a(1 To 7) As String
　Dim i, j, t2, m,cd As Integer
Dim s, t, p As String
　s = Text1.text
　cd=Len(s)
　For m = 1 To cd
　　a(m) = Mid(s, m, 1)
　Next m
　For i = 1 To 2
　　For j = cd To i + 1 Step -1
　　　If a(j) < a(j - 1) Then t = a(j): a(j) = a(j - 1): a(j - 1) = t
　　Next j
　Next i
For t2 = 1 To cd
　　p = p + a(t2)
　Next t2
　Text2.Text = p
End Sub
