When you insert a Web DataWindow DTC in a Web page, the following text is added to the page source between two METADATA comments:
An <OBJECT> element that embeds the Web DataWindow DTC ActiveX in the page. The control provides the information to manage the server component that generates the client control. The OBJECT element has parameters that keep track of various kinds of information about the DTC definition.
For example, the OBJECT SourceFileName parameter specifies the PBL, PSR, or SRD file that contains the DataWindow object definition. This value is set to an empty string if a Web DataWindow Container component is the DataWindow source.
Server script generated by the DTC that provides logic for accessing the Web DataWindow server component. To allow you to target multiple application servers from the same source page, platform-independent code is generated that takes advantage of the capabilities of the Web Target object model.
The OBJECT element in the METADATA comment is required only when you are authoring the page; it is not needed at execution time. However, when the application server processes the page, it executes the generated server script on the page and returns the resulting HTML to the Web browser.
