Well, I'm kinda new at it myself, but here is what I've found. What you want
is the TestCommand Method (at the form level). Here's a sample of something that works:

TestCommand(cmdCode as Integer) as Long

   DIM CurrSec as Integer
   CurrSec = second(NOW)

   fldTemp.value = CurrSec

   IF (gSecInterval > 0) and (gLastSec <> CurrSec) THEN

      IF CurrSec mod gSecInterval = 0 THEN
         frmLocks.repLocks.query()
         gLastSec = CurrSec
      END IF

   END IF -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-

This in the TestCommand of one of my forms. gSecInterval is user-set as a value of how often to update the form (the form in this case is same as SQL*DBA's locks monitor). For some reason, I have to keep setting the value of *something* to keep this sucker spinning (in this case I use the hidden field of fldTemp). I'm sure that relate's to TestCommand primary function is to see if a user has clicked on a menu or toolbar. I figured this
would be similar to HyperCard's on Idle handler (I use to work on Mac's for a living ;).

Enjoy,
