Hi Bert,
No not yet. Not a lot of time lately.
And to keep it "simple", I was using a simple text-file data reader, which makes it extremely slow for most DB queries - while using SQL server is fast, but not practical for "easy to use" operation for most users.
Best approach will probably be using an MDB access DB. That way it shouldn't require any extra setup and still perform nice.
When some of my friends also get their RFX meter, I'll certainly have to "finish" it for them.
I'll be going into holidays next week, I'll try to find some time to finish it up.
