Hi,
If you want to secure your tables against unauthorised access, the only real direction to take is encryption. It would be nice if a DBC could fire an OpenTable event (or something like that) but that would deter only the most casual of browsers. Have a look at Cryptor by Hallogram, or a similar product. You only have to code a few commands in your main.prg and the remainder of your App runs as is.
