How to make cron script works?

[Aou_Student]

Hello,

I wrote a script to work as cron job. I put it in cron folder but it isnt working although I tried it in another directory and it worked manually! but in cron folder it isnt working neither manaully nor scadulled.

The $cronimage is in its place.

forether, I have some questions need answers. Ill be grateful if I can get these answers.

1- Is threre a general codes required for a script to work as cron job in vb?
2- What if I put a script out of cron/includes directories, will it work?
3- Would script work if its written in pure php, not useing vb functions and variables?
