  hi all ,

I created a GUI application on QT 3.1 on red HAT LINUX. Now i want to run this application automatically just after log in as ROOT. How can i do this . If I want to run my application daily at 4:30 PM then what to do for it.

I tried it using cron but  could not successful . Any idea will be appriciable.

On cron i make a sch.cron file  by writing   
30 16 * * * /root/scheduler/schedule  (my binary file path) and keep this on root directory.

Now I load it into the crontab using command crontab sch.cron .

If i check the schedule work by crontab -l then it shows 

# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/kde-root/kcronWQeztb.tmp installed on Fri Dec 23 19:34:48 2005)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
30 16 * * * /root/scheduler/schedule

# Note: Lines beginning with "#\" indicates a disabled task.

BUT it does not work . any  other idea to do it so, or where i am doing wrong.
