>>I don't use any commercial or otherwise framework
I thought that way till I realized that I had created my own framework.
I had some good teachers ( from IBM when it was a great company) and one principle they emphasized was "When you get something that works, use it over and over."
Their teachings and inherent sloth seem to have settled in.
I'm using code for new VFP applications that I wrote in the early nineties.
Every new .NET app I write uses code that I wrote 15 years ago.
Last week I wrote a .NET app that accessed SQL server and Mysql databases.
It was about 15 lines of new code and lots of inheritance.
I never trusted commercial frameworks, but jut recently I realized that I was using my own.
