I've pulled down a webpage using a WebRequest object, and need to parse it, but first I need to render it since there is scripting on the page. I don't want to use the WebBrowser control because that forces me to jump out of my current function to the DocumentCompleted event, and "lose my place" (so to speak). Is there any way for me to pull down a URL using a WebRequest object and have the page rendered but still stay in my function? I considered the HTML Agility Pack but don't believe it's any good for my purposes because that won't render the scripting.
in the spirt of ignoring the question :-) you should be able to use webbrowser control without loosing you place

In VB.NET, I have a windows form where I have a WebBrowser component. I am using proxies to navigate to pages and some proxies are dead/too slow so I want the program to switch to another proxy.
My question is, how can I detect if the WebBrowser has been trying to load the page for a set period of time e.g. it has been 5 seconds since it has been trying to load the page fully?
I am using HTML elements to automate the web browser btw, not sure if this is relevant information though.
I have a page on my web application which has a chart that gets retrieved using a timer. Is there a way to avoid the flickering everytime the chart is redrawn?
Since It's a web application, I guess the doublebuffer property isn't available, or at least I didn't find it and assumed it's webform related.
I would appreciate any help in the matter.
A quick and easy but not suggested solution is to call the redraw manually and remove the event.
So you would remove the event handler and you call the function that redraws the chart when you think is required. i.e After the resize is done or after a value is changed etc.
Since it is a web application, I guess the redraw you are talking about is made using a browser page refresh.
If so, you should take a look at Microsoft Ajax Framework, and a UpdatePanel control to just refresh the specific chart part of your page. Should be smoother then.

I have a webbrowser control that points at a webpage that holds some fields that change quickly. When these fields change the server seems to request that the webpage refreshes. This poses a problem if programatically interact with the webbroswer. Is there anyway to force the webbrowser to not refresh? No real code to show. since I'm hoping this is a one line property I can create/add.
Maybe you are looking for the WebBrowser.Stop() Method (MSDN)
I have a windows application with a tabcontrol. One of the tab of the tabcontrol has a webbrowser control.Now the issue that I am facing is when the focus is inside the webbrowser control, the normal Ctrl+Tab functionality of the tabcontrol is not working.I want the Ctrl+Tab to change the selected tab of tabcontrol even when the focus is inside webbrowser control in selected tab.How to achieve this ?
I have already tries overriding ProcessCmdKey.but it does not get hit when focus is inside webbrowser control.
I also tried registerhotkey method ,it works but it locks the Ctrl+Tab hotkey within my application & system doesn't respond to any other Ctrl+Tab presses outside my application when application is running, which is expected behaviour of registerhotkey.
Here is the code you need:
If WB.ContainsFocus Then
MsgBox("We have focus, disappearing...")
WB.Document.Body.RemoveFocus()
End If
Now, the question is, when to run that code. If you put it in the WebBrowser1_GotFocus event, you'll need to turn it on and off. Turn the code off if the user is interacting with the WB Control, and turn it back on when they are not and when you expect to be experiencing the problem you've mentioned.
Of course, you could add another line to ensure a particular control/tab/panel etc gets focus after you remove focus from the body. Also, here are 3 other SO questions that have answers which may help you, but these will take you in directions different to the direction I've provided, probably due to the fact that the questions are not identical to yours, but are similar enough to be useful (not listed in order of preference).
Prevent WebBrowser control from stealing focus?

Focusing WebBrowser control in a C# application
UPDATE:
I just wanted to add, instead of the .Body.RemoveFocus() you could do this:
WB.Document.Body.Parent.RemoveFocus()
Which I prefer, since the .Document object didn't have an explicit .RemoveFocus method on the intellisense I was gettign in VS2012 RC. This is probably referring to the HTML tag (and not the .Document object) and since the html tag is the only parent to the body tag, it makes sense, and there is no "HTML" object directly available in the intellisense under object, since you can get it via other means, so it's just more convenient doing it this way.
Cheers, and let me know if you need more info on anything.
How can i make it where you click button 1 and on a page like www.youtube.com/shanedawsontv in webbrowser1 it will click the text Add as friend cause they don't have ids for that please help
You'll likely have to use the WebBrowser Control's DocumentText Property to get the HTML of the page so that you can parse the required HTTP request required to add the user as a friend. That's likely to be no easy task with YouTube as it will probably be using hidden fields and Javascript (from a separate .js file) to make the request.
