All About Visual Basic

Microsoft Visual Basic is new evolution in current era, whenever we need to develop any window-based application then we use VB. There have a lot of versions in VB like VB.6, VB.7, VB.NET etc & we use VB.6 version to make this project. The basic idea of introducing visual Basic to the world was to provide a rapid Application Development Environment to the developer. Visual basic provides the first example of successful component object modeling programming in which third Party available components could be added to provide additional functionality. It provides support for ODBS and RDO data access methods. Which has brought Visual Basic into a realm of serious development tools? Through this Language Web Browser based application can be written with the help of Microsoft DHTML, Page designer. The Visual Basic is the technology leader implementing the new ways of doing the thing, before any other development tool.

1.ADO(Active data object):
This new data access technology features a simpler object model, better integration with other Microsoft and non –Microsoft technologies, a common interface for both local and remote data access, remote and disconnected record sets, a user accessible data binding interface and hierarchical record sets.

2.OLEDB Support:
OLEDB is a set of COM interface that provides application with uniform access to data stored in diverse information sources both relational and non-relational. These interfaces support the amount of DBMS functionality appropriate to the data source, enabling it to share its data. ADO (Active data control) is the way that programmers access OLEDB.

3. Interactive development: The traditional application development process can be broken into distinct steps:
a. Creating a user interface by placing control on forms.
b. Setting attribute for the forms and control displayed on the forms.
c. Writing code
d. Testing the program and running it. Visual Basic has powerful debugging tools for this purpose.
e. Visual
