>If I have a text box on top of a combobox, is there any way to keep the text box in front of the combobox even if the combobox has focus?

No, if the combo gets focus it comes to top. The only way is for you to prevent the combo from getting focus until you are ready by using the combo's ReadOnly or Enabled property. Set either one to .T. and the combo cannot get focus, wehn you are ready for the user to use the combo then set the property to .F. to allow focus to it.
