I *think* so.

>Hey, John, I was wondering the other day about running FXPs when both 8 and 9 are installed. I know an EXE has an indicator about which version it was compiled under and should run under, but what about the FXP? Would a FXP compiled under 8 run under 8 even though 9 is also installed?

>>Not a problem. VFP 8 and 9 work fine on the same box at the same time in most cases. If each service is it's own process I don't see a problem except, possibly, port issues that would be an issue regardless.
>>
>>>There is a class that I need to create a service that is only available in VFP9. It will send/recieve info using ports. There is a VFP8 application that will also communicate using these ports. Any issues having the service created in version 9 with the app in version 8? Thanks!
>>>
>>>UPDATE: It's not the ports that I'm concerened with, but rather running VFP9 and VFP8 on the same box. Or any other issues anyone can think of.
