How to find out if the loaded page is error page or valid page in System.Windows.Forms.WebBrowser?

I am using


System.Windows.Forms.WebBrowser

control in C# for displaying some pages. I want to do some custom work when the user clicks on a url of a page which does not exist.


Basically I want to set some values when the browser displays the following message


The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties

How can I get the status so that I can differenciate between a page loaded and error page?

DocumentCompleted event when the page is fully loaded in WebBrowser form (Windows Forms C#)
Programming Languages

I use the DocumentCompleted but this gets fired multiple times. Now I've seen this example if (e.Url.AbsolutePath != this.webBrowser.Url.AbsolutePath) which is used to confirm that the requested file is completed loading but this gets fired before anything else (like images) on the page is loaded. Thus I'm still not able to tell when a webpage is fully loaded.


Is there a way to ensure that the webpage has fully loaded and there's nothing being loaded?


Page with Frames in System.Windows.Forms.WebBrowser
Programming Languages

I have a desktop C# application with a WebBrowser control. This control loads a https page containing a few frames. Im trying to access the form elements in one of the frames using similar code to this one:
WebBrowser1.Document.Window.Frames("theRightFrame")....
; however, I am getting some Security exception being thrown after accessing members of HtmlWindow (the frame object). I googled about this and seems the explanation is to have frames referring to different domains (servers). But in my case all frame pages are loaded from a single domain (server).
I wonder is anybody experienced this kind of problems and what is the workaround. I
