Messages in Paradox

Hi all again:
Excuse my poor English.
I hope somebody can give me other solution about this problem.
I have to run a procedure in application(1) in my PC from  application(2)
sites in other network PC.
I've solve this problem putting a flag in a Network Paradox
Table register that is refreshed and read once per second by (1) using
a TTimer.If this flag is changed by (2) then (1) runs the local
procedure but I think that may exist another better solution.
Please,could anybody help me?

I've tried to use the OnChange Event in (1) but it doesn't works.

Thanks a lot.
