>I had coding DOS-FOX over 10 year, but in VFP50 just 3 months. I feel that i am poor in it, i take more 6-7 times of hours to finish a job as in DOS mode. (all the time run around in window, buttom, grid, call a sub-program from screen, back to screen from sub-program, enable this, disable that.......)

3 months is not enough time to master the intricacies of OOP methodology IMHO.
Take time, don't rush on learning and you will reap the reward. Take another three months with consistent attitude and passion in learning, and then compare your code and application that has done three months ago, and you will see the difference, and you will to yourself : "Incredible, I have gone this far!"
