Creating a routinely scheduled task to modify ststus of icons

[LcdCyn]

I have been using the HP Openview NNM SDK (APIs) to create new commands to be used by my application. My job is to add to my current HP Openview application a new command that runs every x minutes and updates status of my icons based on SNMP data. I have an idea about implementing C language routines to send SNMP get (and get-next) requests and recieve the responses. I also have an idea of how to set the status for my application (my objects). But I do not know how to have HP Openview run my task every x minutes.

Help!
