Compiled Components

[Previous] [Next]

In addition to writing business services components that use HTC, we could write business services components in Visual Basic, Java, or C++ and create compiled objects that are used by the HTML page. (It is also possible to create a compiled HTC, but this can only be done with C++, and the process is extremely complex.)

For example, you could create a business services component using a Visual Basic object that uses the DOM object to work with the XML data. We will not demonstrate how to do this here as the code we used to work with the DOM in Chapter 11 can be used to make either client or server components.

A compiled business services component might run more quickly than an HTC, but a compiled component might need to be installed on the client computer. In a controlled environment where you can be certain that a compiled component will easily install on every client, a compiled component may be the better choice. In an environment in which every client has Internet Explorer 5 installed, but there are many different types of clients, it might be better to use HTC.
