script to show a count down timer in a message box.

Hi,

We are looking for a count down timer embedded in a message box.User will be having 2 options.

1.User can click on the OK button in the message box (timer ends) and continue with the next step.

2.Timer will be counting for 10 minutes. After that it will execute the next step automatically.

Can we achieve this through a vbscript..Please advice.
