USER FRIENDLY & INTERACTIVE
This is the most common feature of Visual Basic. As a user you will find very few This is the most common feature of Visual Basic. As a user you will find very few complain about its user friendliness. You have readymade controls and excellent complain about its user friendliness. You have readymade controls and excellent MSDN (Microsoft Developer Network) help for technical doubts. You have various MSDN (Microsoft Developer Network) help for technical doubts. You have various window sections like Immediate Window, Watch Window etc. to help in coding, window sections like Immediate Window, Watch Window etc. to help in coding, testing and debugging during the entire phase of software development life cycle.
