Thank for your advise. My idea is also sone what same but formula part is extra. But as I was good maths student. I doubt arised. In a formula calculation their can be two key which can give same result. But very rare case. I also love to solve brainer teasers. So if you want you can give your formala and I will try to solve it. But for my software that high security is not needed.

But for it I have to write a full code. Atleast tell me is their any option to make a table encryted or again some code for it. If any other software available.

Plus I have written a code to dial a number but problem that I am facing is that when the number is dialed and the person at the other end pick his voice is also heard. and if the modem speaker is off the user doesn't know whether he has got the connect or not.

help.
