Hello, Got the links and found 2 be very useful one thank u. Want 2 create a RAD tool? (Rapid Application Development) tools for PC interface? Delphi is the best choice. I have used it and works fine. The main advantage of using Delphi as a RAD tool is that. Delphi has got aCLX (Cross compiler) built in so that u can easily import a windows based application to linux based one. The linux version of delphi is Kylix. Regards, Prasad.S.R
