Thank you Sergei and David for your answers.
I'm sorry that I did'nt reply earlier, I will pospone my VFP project because it's too difficult for me, and I will do it again in FP26.
Poor me!!! :)
In a couple of months I will have the time to take a look at your replies.
Thank you very much again to both of you!
