Preface
As the Internet develops
very fast, people tend to rely on the web to exchange information.
The Static HTML webpages no longer can satisfy their needs for
communication because they lack the ability of interacting with
users. To address this issue, many laguages like Javascript, PHP,
and CGI are devised. VBScript is Microsoft's alternative for Javascript.
Very similar to Visual Basic, it provides the easiness of constructing
Graphic User Interface, and event-driven mechanism. Using VBScript,
we can easily embed all VB elements, such as buttons, textbox,
and menus, in a webpage, so that the same functionality can be
achieved by just browsing the website.
ASP (Active Server
Page) is a special kind of webpage. It becomesmore and more popular
because it can use the resource of web server to do computation.
ASP can be easily written using VBScript. In this tutorial, I
will first give a short introduction on some basics of VBScript
programming, then I will demostrate a project in which an ASP
(Active Server Page) solution is created using VBScript, to achieve
remote data acquisition through serial port of the server.
I assume the readers
of this tutorial have some knowledge of the fundamentals of Visual
Basic. To write VBScript in HTML, the only software you need is
a text editor, such as Notepad. You can also choose to use webpage
softwares like Macromedia Dreamweaver, they allow you to see the
webpage GUI while editting the HTML.
