Pass variables to programm

How can I pass a variable to a b4p programm?
I think i should do it over a command line parameter but the programm should be running all time and not just been launched and stopped everytime.

I also dont want to do it over registry or files who are checked constantly

Thanks for your help

You could do this with the Network library. The running program implements a Server object and occasionally checks the Pending property. The program that wants to send the information implements a Client and connects to the server when required.

An example is here http://www.b4x.com/forum/showthread.php?t=1130

That sounds great, I hope it works with my version!
