>>I have a class built that communicates with a hardware device. This device may be connect via serial, ethernet or ftp. The properties of the class set all the necessary parameters of the device... tcpip/serial/ftp, address, port, bps, parity, etc. The class is instantiated, properties are set (based on settings stored in a device table) and the communication takes place. This works great. But occasionally after the class is instantiated and the properties are set, the device needs to be changed to a different one. This requires access to the device table. I don't like the idea of tying the class to a table to query it. I have don't have any ideas on how to keep this class abstract yet still query the data in my device table. Any ideas?

Yes but then I have to hard code field names and queries into the class. That doesn't seem like a good idea does it?
