Hey, I think it's a simple code but I can't resolve how to do it..
I have a combobox and I want to "Add All" to a listbox, but without removing them from the combobox..
Here is my code, please help me fix it:
If ListBox1.Items.Contains(ComboBox1.Items) Then MsgBox("You can't add those items twice.", MsgBoxStyle.Exclamation) Else Dim Item As String For Each Item In ComboBox1.Items With ListBox1.Items .Add(Item) End With Next End If
