are you meaning something like this?

C# Syntax (Toggle Plain Text) 
  1.  foreach (HtmlElement link in webBrowser1.Document.Links)
  2.             {
  3.                 bool isValid = false;
  4.                 string linkItem = link.GetAttribute("HREF").ToString();
  5.  
  6.                 Uri urlCheck = new Uri(linkItem);
  7.                 WebRequest request = WebRequest.Create(urlCheck);
  8.                 request.Timeout = 10000;    // 10 seconds
  9.  
  10.  
  11.                 WebResponse response;
  12.                 try
  13.                 {
  14.                     response = request.GetResponse();
  15.                     isValid = true;
  16.                     Console.WriteLine("Good");
  17.                 }
  18.                 catch (Exception)
  19.                 {
  20.                     Console.WriteLine("Bad"); //url does not exist
  21.                 }
  22.  
  23.                if(isValid)
  24. 	   {
  25. 		listViewLinks.Items.Add(link.GetAttribute("HREF").ToString());
  26. 	   }
  27. 	}

Yeah, that's pretty much what I was meaning. Appears I had that at one time, just not at the same time! That code seems to work, but when I click the "Check Links!" button, I just get "A first chance exception of type 'System.Net.WebException' occurred in System.dll" for the links. I know that the links are good. Sometimes it also says "Bad" also.

what are the href's coming in as?

also capitalization

if it also says bad, then the exception didn't occur in that place, what are links coming in as, and what are they being resolved as?

In my first code, the links showed up in my listView as "http://www.webpage.com/." Now nothing is showing up in my box. I don't know if that is because it is waiting for it to check all the sites or what. It returned back "Good" on the very first link on the page, which also has the same url as the page that I was checking the links on, but it still didn't show up in my listView. Now every link, every 10 seconds is gives me "Bad", then "A first chance exception of type 'System.Net.WebException' occurred in System.dll" at the same time.

It doesn't leave the trailing / after the aspx, html, php, or anything else. I tried to check the links on microsoft.com and got an unhandled exceptions error. It said something about their being a wrong uri prefix here WebRequest request = WebRequest.Create(urlCheck); . I also tried adding an extra / and even a /r/n to the link, but it didn't make any difference.

Tried it, no difference. I changed it back and now I'm getting alot more "Good" links. I still get alot of "first chance exceptions" though.

What does the exception say?
Have you allowed for redirection? Eg if you went to www.somesite.com chances are http is telling "hi thats nice for you, now ask for say index.html"
Did I just hear "You gotta help us, Doc. We've tried nothin' and we're all out of ideas" ? Is this you? Dont let this be you! I will put in as much effort as you seem to.
