Network Programming in .NET

I recently was using the Full Source utility by ThunderMain, and I was curious to see if I could make my own context menu for Internet Explorer. A useful utility I thought of using was a "send to a friend" utility.

I created the following registry key

HKEY_CURRENT_USERSoftwareMicrosoftInternet ExplorerMenuExtSend to a friend

and set the default value to

c:windowswebsendToAFriend.html

Which contains the following

<script language="JavaScript">
window.open("http://www.pop3webmail.info/reply.aspx?url=" + external.menuArguments.document.URL);
</script>

From the page on www.pop3webmail.info, it automatically fills in a message saying "Please Visit: (whatever url)"
