Running Dialog using Cron

Folks,
I have a solaris 10 system.
I am having trouble with cron to run a dialog command.
When I simply execute below using a cron it does not work.
I am new to the forum, please help me to understand it better.

Thanks in advance.

#!/bin/sh
dialog --infobox "Please wait " 10 10

That's probably, since cron jobs are intended for automatic maintenance actions, scripts started by cron do not get an TTY allocated, which makes dialog (or any other user interaction) impossible.

Thanks Puldi,
I have a shell script which I run with Cron every minute.
The output of that script is some decisions whcih I wanted to pop up using dialog.
What other options I have to execute similar taks automatically.
