About VB (Visual Basic)
Visual Basic & the Features of Visual Basic 6.0
Visual Basic is easily learnt if you know the basics of computer programming
concepts.
It uses much less code than C or C++, and runs faster (except for extensive
calculations) although the difference is only nanoseconds.
Visual Basic's features include:
- Runs ActiveX Data Objects (ADO) to read remote databases over the
Internet
- Easier integration of ADO and Component Object Model (COM) Objects
- Makes Windows programming easier because of it's Rapid Application
Development (RAD) environment, and
- The ability to build a variety of applications for mobile users, and
can write client/server database applications whether or not they are
connected to a LAN or the Web.
Visual Basic is often used to pull data from a database for the display
within a Web page. It is relatively easy to create a functional, traditional
user interface via VB - the VB environment is enhanced through add-ins
which can created in VB or Visual C++.
With VB 6.0s Data Environment Designer (DED), you connect to a database,
drag and drop record sets to create a hierarchical view of the data, then
drag and drop this data object into a form. DED automatically lays out
a user interface. The data object is a COM object, complete with properties,
methods and events. These are easily manipulated with your Visual Basic
code.
IIS (Internet Information Server) applications
IIS applications combine Visual Basic code with HTML template files and
HTML code to form dynamic web pages in a complete application. Generic
HTML code is fed to the client's browser after processing on a Windows
server (via IIS).
IIS applications are founded on Web Classes, a new designer that allows
a Visual Basic application link event procedures [clicking on a hyperlink,
loading a page, retrieving an image from the server] to any element in
a web page that invokes a call to the server.
Incorporating ASP allows developers to write code in response to various
events. IIS applications wrap the ASP object model, which gives ASP applications
control over the environment allowing you link VB code with HTML objects
contained within a Web page.
