Problem with disabled button

[lihui]

Hi all, i found out that user could still press disabled and greyed out buttons in front panel. Is this suppose to be the case? It actually pose some minor risks to my program though. Is there anyway to disallow them to press it as well. Thanks.

Hi!

I got a little confused about what you wrote, what the buttons still where enabled then i disabled mode.
So i did a little test VI, see attachement (LV 6.1).
As long as the VI is in execution mode (running) you can't press the button if it is in "disable" or "disabled & greyd" mode. But then it stop executing you'r able to change the value of the control.

Hi,

You are probably using the event structure. An event "mouse down" is
genetared when a button is pressed, even if the button is disabled (and it
should, because the mouse *is* down on it).

You should use the "value change" event. This is only generated when the
value is changed, and this doesn't happen is the button is disabled.

Regards,

Wiebe.

Hi Lihui,

Users should not be able to press disabled and greyed buttons on the front panel if the VI is running. However, if the VI is running and a user is able to press the button please post a simplified piece of code that shows this functionality.

Have a great day!
