VBA excel - adding combo box item to list box - vba

Question

guys I hope someone can help me with this one.
I have a combo box that has data from a named range and I would like to select a value from the combo box and add it to the list box.
Currently I can add an item into the list box with a button but once I add another it overwrites the current item.
Also It needs to be able to add an item at the bottom if the list box already has some values in it.
I think it has something to do with finding the last row but I'm not sure, any help would be highly appreciated :)

Dim i As Integer
With Me.lb_lease
.ColumnCount = 3
.ColumnWidths = "200;50;50"
.AddItem
.List(i, 0) = cbox_hardware.Column(0)
.List(i, 1) = cbox_hardware.Column(1)
.List(i, 2) = cbox_hardware.Column(2)
i = i + 1
End With

I suggest to separate the actions of setting up the listbox and adding items to it. The procedure below will set up the box and clear all existing content. Change the names of the worksheet and the Listbox to match your circumstances. The code will also work if the listbox is in a userform.
Private Sub ResetListBox()
With Worksheets("LibraryAccount").ListBox1
.ColumnCount = 3
.ColumnWidths = "80;50;50"
.Clear ' delete current list
End With
End Sub
The next procedure adds an item to it. It requires a semi-colon separated string, like "One;Two;Three". You might concatenate it from your combobox result using ListIndex to identify the row. The procedure will disassemble the string and add it at the bottom of the list. Worksheet and ListBox names must be changed.
Private Sub AddToListBox(AddArray As String)
Dim Arr() As String
Dim i As Integer
Dim C As Long
Arr = Split(AddArray, ";")
With Worksheets("LibraryAccount").ListBox1
i = .ListCount
.AddItem
For C = 0 To 2
.List(i, C) = Arr(C)
Next C
End With
End Sub
The procedure below is for testing the above procedure. You can run ResetListbox and then call TestAdd several times.
Private Sub TestAdd()
AddToListBox "One;Two;Three"
End Sub
