This sample program demonstrates the use of TDHTMLEventHandler component to display additional information about each link on a loaded Web page.
The code loads a Web page into the embedded WebBrowser control and enumerates its Document.Links collection. For each link, OnMouseOver and OnMouseOut events are intercepted using two separate TDHTMLEventHandler components. The program also makes up some information about the target location of a link (pretending that it has pre-fetched the destination URL and analyzed it in some way), packs it into a variant array and passes to the event hook being created.
After you press the [Hook] button on the form, the sample will display some bogus "additional information" for any link on this page. Below are some random links to test this functionality:
| BetterBrowser's home page My personal page Other components from my collection |
AltaVista Search Engine |
| HREF Tools Corp. |
| BetterBrowser's component collection |
