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:
Visual Basic is commonly 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.
By the way...
IIS applications resist reverse engineering and code modification.
