I want to create a dll that can forward you to a webpage when you click on the mailto: link in a web page. I found the registry keys for this and can get it to work with an EXE file, but in order to get it to work when you click on the mail icon on the toolbar, and choose New Message, Send Link, or Send Page, it is using the DLL that is in the registry assigned for the current default mail client. I just need to know how to get it to send the browser to my own web mail client. Hotmail does this if you choose it as your default mailer. Thanks.
