When you debug a DHTML application, you have the full Visual Basic development environment at your disposal. You can use all the tools available in Visual Basic — breakpoints, watch variables, debug statements, and so on — to debug your project.
Note A file named VB6DEBUG.DLL enables you to debug your DHTML application across processes. Do not delete this file or you will not be able to test your application.
The settings in the Debugging tab of the Project Properties dialog box determine whether the system waits for you to tell it what to do when you go into run mode or automatically starts a page designer you specify, displaying its page in the browser. You can also indicate whether to open a new instance of Internet Explorer or use an existing instance.
When Visual Basic runs the application, it inserts an OBJECT tag into the body of each HTML page used in your application. The OBJECT tag is used to download the HTML page when the application is deployed. The tag includes a classID used to include of find the page in the Windows registry, an ID used to reference the page in the run-time DLL, and a CODEBASE tag used to tell the browser where to find the page if it’s not already on the client’s computer.
