比如有combo1和combo2，当combo1选择“电脑班”时，combo2出现“硬件”，“软件”等选项，当combo1选择“网络班”时，combo2出现“维护”，“设计”等选项，请问如何编写代码，急需解决，谢谢
Private Sub Form_Load()
Combo1.AddItem "电脑班"
Combo1.AddItem "网络班"
Combo1.ListIndex = 0
End Sub
Private Sub Combo1_Click()
Combo2.Clear
If Combo1.Text = "电脑班" Then
Combo2.AddItem "硬件"
Combo2.AddItem "软件"
Else
Combo2.AddItem "维护"
Combo2.AddItem "设计"
End If
Combo2.ListIndex = 0
End Sub
if combo1.text = “电脑班" then
combo2.clear
combo2.additem "硬件"
combo2.additem "软件"
elseif combo1.text = “网络班” then
combo2.clear
combo2.additem "维护"
combo2.additem "设计"
end if
Private Sub Combo1_Click()
Combo2.Clear
