running form/macro in a scheduled task?

[Long Nguyen]

(outlook 2002)
I have a requirement to write a job that can be run weekly. The job is to
check through all outlook custom forms in a folder (all forms have the same
message class) and lists out forms that meet certain condition.

I could write this check through vbscript. However what I am not sure is
how can I schedule a task to run this check weekly? If I write the check as
the code behind a custom form, how can I schedule task to run this custom
form? I could write a macro to do this check, but I do not know if we can
schedule a task to run the macro?

Thanks
Long
