ActiveX components in ASP

The Active|activex ActiveX component runs on the Web server as part of the web-based application. Components provide the primary functionality of the application, such as accessing the database, so that you do not have to create or re-create the code that performs these tasks.

　　Database access

You can use the database access component to access databases in your application. You can then display the entire contents of the table, allow the user to construct the query, and perform some other database queries on the Web page.

　　Ad Rotator

You can use the Ad Rotator component to alternately display an image and provide a link from the displayed graphic to another URL. Save the ad list in a text file; The Ad Rotator component displays them according to the instructions in the data file.

　　Content Rotator

The Content Rotator component automatically loops the HTML content string on a Web page. Each time a user requests a Web page, the Content Rotator component displays a new HTML content string based on the information specified in the content Schedule file.

Because content strings can contain HTML tags, you can display any content type that HTML can represent: text, graphics, or hypertext links. For example, you can use this component to cycle through a daily premium or hypertext link, or to change the color of text and background each time you open a Web page.

　　Browser Capabilities

By using the Browser capabilities component, you can tailor the content that is sent to the browser based on the capabilities of the browser.

　　File Access

The file Access component provides objects that you can use to retrieve and modify files in your computer's file system.

　　Content linking

The Content linking component makes it easy to provide logical navigation for an. asp file in an application. Instead of maintaining URL references in many. asp files, you can simply specify the order of the. asp files in a text file that is easy to edit.

　　Collaboration Data Objects for Windows NT Server

The collaboration Data Objects for NTS component provides the message objects used by the Web application. This library enables you to easily and quickly add the ability to send and receive messages on your application. You can create programmable mail objects and then take advantage of their properties and methods to meet the needs of your application.

　　MyInfo, Status, System, and Tools

The MyInfo, Status, System, and Tools components provide compatibility for applications developed on the Macintosh and on computers running Microsoft Windows.

The MyInfo component tracks the personal information of the Web site owner, such as the organization name and address of the operating Web site and the settings for the Web site, and whether the Web site has a guest book.
The Status component tracks information about the Web site, such as the number of visitors and the number of HTTP connections.
The System component creates a status object that contains server state information. The current server state is only available on the Personal Web server for Macintosh.
The Tools component provides a way to generate random numbers, check whether a file exists, or process an HTML table.

　　Page Counter

The page Counter component counts and displays the number of times the Web page was requested. Writes the captured number to a text file at a certain interval so that the data is not lost when the server shuts down.

　　Permission Checker

The Permission Checker component tests the access of a WEB user to a file or to a page. You can use the Permission Checker component to customize ASP-based pages for different types of users. For example, if your Web page contains hypertext links, you can use the Permission Checker component to test the user's access rights to the appropriate Web page and ignore pages that users do not have access to or invalidate those links.
