I'm developing a datacollection program. I use a USB interface to
communicate with my data collection tools and then using the ddl,
write the data into a database.

Now, the sensor gets polled every half second and detects when pieces
go past it. The application then increments a counter in the class
attributed to the sensor.

The actual user interface is getting modified all the time. Right
now, I have to wait for downtime before I can put in modifications to
the interface. What I would like to do is create an application the
would just collect data from the interface and an application the the
user interacts with. This way, whenever I want to make an update I
just shut the front end, the data keeps collecting and no one's the
wiser.

The problem is this: How do I communicate between the two
applications so that when a new job is started the data collection
resets the counters for the data collection? Is this possible?

You'll have to use some sort of remoting technology. .NET remoting, WCF, or
web services, etc.

Or you could use the database to pass data between apps - but this is
typically a bad idea in a multi-user environment.
