Dear Michael:
Here's a quote from a post by Jeff Conrad which itself quotes previous
The only way I've heard of is to hide it with another text box or label
control as you mentioned.
Here are some past posts by Access MVPs Ken Snell, Cheryl Fischer, and FredG
on this subject:

If you're trying to hide the drop-down arrow, use a small trick to make it
appear as if the combo box has been changed to a textbox:
Create a box on the form, and size it so that it will fit over the arrow
part of the combo box. Place the control on top of the arrow part of the
combo box. Be sure that it's set to be on top of the combo box control (move
to front). Have the background of this box be the same as the background of
the detail part of your form. Set its visible property to yes.
When the form is viewed, the combo box will appear as if it's a textbox. The
user won't be able to click the "dropdown" arrow because the box prevents
access to it.
In your code, when you want to "turn" the "textbox" into a combo box, set
the visibility property of this box to No. Set it back to Yes when you want
to "turn" it back into a textbox.
