I am using the following code behind a button click to open a form whose code is shown further on. This loads a listbox on the form.
When the user makes a selection from the listbox it sends this back to my original ComboBox.
The listbox has one column. I now want to do this for a multi column combobox and listbox. How do I do that?

Private Sub btnManufacturer_Click()

    oForm = Me.Name
    oCombo = Me.Manufacturer_Combo.Name
    DoCmd.OpenForm "f_List", , , , , acDialog

End Sub

Open in new window

Private Sub Form_Open(Cancel As Integer)

  Cancel = -1
  CopyComboBoxSettings Forms(oForm).Form.Controls(oCombo)

  Cancel = 0

End Sub

Private Sub CopyComboBoxSettings(ByVal CSourceComboBox As Access.ComboBox)

  List1.RowSourceType = CSourceComboBox.RowSourceType
  List1.RowSource = CSourceComboBox.RowSource
  List1.ColumnCount = CSourceComboBox.ColumnCount
  List1.ColumnWidths = CSourceComboBox.ColumnWidths

End Sub

Private Sub List1_Click()
    Forms(oForm).Form.Controls(oCombo).value = List1.value
End Sub
