2. VB as Programming Language Visual Basic is a Programming tool that allows user to develop Windows or GUI ( Graphical User Interface ) applications. It means that rather than writing numerous line for code to describe the appearance and location for interface elements like C , C + + or Basic . User can simply drag and drop pre-built objects into the form window on computer screen. VB is a much enhanced version of BASIC programming language ( BASIC is Predecessor of VB ) . The main difference is that the VB can create windows programs by just Drag & Drop where as BASIC could only create DOS programs or work only in CUI (Command User Interface ).

4. Event & Event Procedure An event is an action recognized by an object, such as clicking a mouse or pressing a key. User can write code to respond to that event. Each object has different events that it recognizes. An event procedure is a section of code that is executed when an event (like clicking a command button) takes place. Event procedures can be added to your project in the code editor window.
7. Interface of Visual Basic When user start the window it display a screen having certain option. With the help of this screen user can select the type of project user want to make. Visual Basic environment is platform provided by VB to develop and execute a project . This environment consist of different platforms or control tools and various other options.
