>>Hello again,
>>
>>I have a check box linked to a logical field. Sometimes in forms, I would like to display it's state, but don't want users to change it. I used the Object.enable=.f. property, but users are still able to click on it to change it's state. I also checked the Readonly property, but apparently it does not have that property. Any ideas how I can prevent users from changing the state of the checkbox

Response from 'left field': I also wanted to show such a field -- drew a sunken container and placed a WingDing font chr(252) inside the box. Looks a little different from the VFP check ( I think it looks better ), it is sizable, and totally, completely unable to be changed by the user.
