VB stand for Visual Basic which is a high level programming language and developed from earlier DOS version called BASIC. BASIC means Beginners' All-purpose Symbolic Instruction Code which is easy programming language to learn. The code looks like English Language. In software development Different software companies produced different versions of BASIC, such as Microsoft QBASIC, QUICKBASIC, GWBASIC ,IBM BASICA and so on. But mostly people are used Microsoft Visual Basic today because it is well developed programming language and supporting resources are available everywhere. In addition Visual Basic 6 is Event-driven because we need to write code in order to perform some tasks in response to certain events. Some of the events are load, click, double click, drag and drop, pressing the keys and more. We will learn more about events in later lessons.
