【求救】高手们快来帮小妹解决一道VB组合框添加和删除操作程序

确实太繁琐了，现在上班忙啊，没时间写了。等晚上要是有时间就帮你写一个。
花了点时间写了一下。那个隐藏的功能你知道了就自己加进去，我就没写了。可能有bug，好久没用vb了，挺生疏的。
还有我在日本，机器都是日文系统，vb也是，显示不了中文，其中的名字什么的你自己改成对应的就可以了，我想这不难吧。

晕，果然有bug，改了一下。vb6.0 pass如果再有bug你自己改吧。

Public c As Boolean 'to make sure there are not same items in combo1
Public l As Boolean 'to make sure there are not same items in list1

Private Sub Command1_Click()

If l = True Then
If c = True Then

If Combo1.text = "" Then

End If

最后声明一点，不是为了要你的分，我玩c++头痛，想休息下，哈哈。

小妹妹,问题很简单,就是繁琐,10分太少了,因为太浪费时间!!

Private Sub Command1_Click()
List1.AddItem Combo1.Text
Text1 = List1.ListCount
End Sub

Private Sub Command2_Click()
If List1.ListIndex = -1 Then Exit Sub
List1.RemoveItem List1.ListIndex
Text1 = List1.ListCount
End Sub

Private Sub Command3_Click()
List1.Clear
End Sub

Private Sub Command4_Click()
'不写了,按照你的代码就行了
End Sub

Private Sub Command5_Click()
Unload Me
End Sub

第4个按钮,就是切换list的可见状态用的!!

看书，看书，再难的知识点书上都会有，包括参考书，建议看清华出版社的，比较精髓

我对这些一窍不通
