When I click button 1 for the first time I recieve the error "Object reference not set to an instance of an object." but when I click it the second time it returns the elements text perfectly.
I thought the wb.document element might not be instantiated so I've tried navigating to a page (google's homepage) before loading the page I want put with no success.
I also thought that maybe it wasn't giving the page time to load so I added the sub to deal with the documentCompleted event but this also returns nothing (though wb.document.url is set correctly to the webpage I want)
I'm looking for a way to do this check the currect html that in (webbrowser1) for this text
by <a href="/text/text" if it found then continue loop or do nothing if there is no match to do something
I'm not looking to find a href i need it to have find the same thing with "by" before the href
I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:

AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
