>I want one VFP instance react instantly when another VFP raises a flag (couple of). The key word is instantly. Using DBF take some time (0.3 - 0.5 sec) and because there coud be several flags going on and off per second DBF is too slow. I'v tried it also with SAVE TO and RESTORE FROM and it much faster but needs error procedure to handle situation when one application is writing on the same time when another is reading and slows it little bit.

Although I haven't tried them, and don't know how applicable they would be to your situation, there are a couple of technologies that might help you here:

- Microsoft Message Queue (MSMQ)
- Nick Neklioudov apparently has written an article in the February FoxPro Advisor that outlines how to raise events in VFP using (I believe) a VB COM object.
