under properties, make "enabled" False.  This will work for text boxes, list boxes, combo boxes, bread boxes, safety deposit boxes, post office boxes, etc.

readonly combobox:
* either some API (i don't know it...)
* or some vb, which in  the Change and Click event set's the .Listindex value back to the value you want.

* and of course, you can try to use the .Locked = true property, which will enable the user to see all the values (dropdown), but not choose by clicking or using keyboard...

If you want full functionality without allowing change:

1) Since the text portion is "useless", as pointed out above, the style should be set to 2-dropdownlist.  Also, the key presses should be disabled:
Private Sub cboXXX_KeyPress(Index As Integer, KeyAscii As Integer)
   KeyAscii = 0
End Sub

2) Since you don't want the user to change the list selection, but could still want to view the choices, you'll need to save the initial state and reset it any time the user inadvertently clicks on a different selection.  To do that, you'll need two code changes:

Private Sub Form_Load()
  Combo1.AddItem "first entry"
  Combo1.AddItem "second entry"
  Combo1.AddItem "third entry"
  Combo1.Tag = "1" ' give an initial value
  Combo1_Click ' set it
End Sub

Private Sub Combo1_Click()
  ' reset it any time the user changes it
  Combo1.ListIndex = Val(Combo1.Tag)
End Sub

Private Sub Combo1_GotFocus()
  ' capture the current setting any time the user goes to it
  Combo1.Tag = CStr(Combo1.ListIndex)
End Sub

On further review, angelIII's idea of locked seems to be better.  The difference is that the user cannot click on the dropdown list to close it.

Setting the style to 2-Dropdown is exactly what I wanted. Setting enabled=false, or locked=true are not suitable as they do not allow the user to select a list item. I actually want full functionality without the user being able to change the items or add more.
Thanks
