Okay, a few problems here: 1. Go use Google. If you're such a beginner that you can't look it up yourself, there's a good chance you shouldn't be coding as a job just yet. Not to discourage you - just to discourage writing code for important systems before you know exactly what you're doing. 2. Good systems will generally use a database (a way of saving information without manually writing to some file). They also provide a lot of additional things, like increased speed, data integrity, and protection against information loss. What happens to your program if the power goes out? (You'd lose data if you weren't running a database) What happens if the CPU overheats and the system off instantly? (You'd lose data if you weren't running a database) What happens when the listed customer for a transaction suddenly doesn't seem to point to any known customers? (With a database, you have data integrity) Though to answer your actual question, try this: Google Search for visual basic file i/o |

Google is your friend and also in this type of system, a DB is way better than file output as stated above and in a professional environment, no one would buy a system that saves data to a file... |

Well, VB is not my expertise - it's been a looong time since I opened the VB 1.0 books. There is
There are other new funky 3rd millennium ways in more recent VBs I'd assume, and to be honest I had to put the syntax as pretend, because I could be dead wrong. Cheers |

My friend was looking for some sales program and I think it would be helpful for him. |
