Change message in display message to user dynamically?

[dave56]

I want to have the Display Message to User vi pop up and notify the user that the computer will reboot in x number of seconds, where x is constantly decreasing. Is this possible? I have tried sticking it in a for loop and the message won't change without clicking on the button. Also, when the time does reach zero, how can I have it destroy that pop up box?

you can't use Display Message unless you convert it to a normal VI and do a lot of modification. It simple though, to create your own pop-up that does what you want. Look at the subVI in the attached file. It uses the Elaspsed Time function to create the time left and the window appearance properties to show and then close itself. There are also some shipping examples on creating your own dialog box or pop-ups.
