Tutorial: Visual Basic File Handling
\"The usual model for all computer programs is that a user inputs data and the computer saves it. Okay, there\'s a lot more than that to a computer program, but the point is that virtually every program is written to save data that is entered or data that is calculated by the software itself. If you want to be an expert VB programmer then you\'ll need to know a lot about how VB handles files - what is possible and what is not, plus how to do something in the smallest code or in the least amount of time. To do this you need to understand the file handling features which VB offers.\"
