c# - Accessing controls through threads -

i use webbrowser control in c# check couple search engine results sometime no reason gets stuck. first thought make each searching function thread , use thread.abort() timer couldn't handle ui controls (including webbrowser) no matter i've tried. has solution me? example great cause tried many things , keep getting these exceptions.

i believe can use webrequest in background worker & avoid difficulties of dealing com threading model. can use webrequest.timeout handle think taking long.

try this:

   static void main(string[] args)    {        backgroundworker bg = new backgroundworker();        bg.dowork += backgroundworker_dowork;         bg.runworkerasync(new list<object> { "http://download.thinkbroadband.com/512mb.zip" });        while (true) {}    }     private static void backgroundworker_dowork(object sender, doworkeventargs e)    {        console.writeline("starting operation.");        backgroundworker bw = sender backgroundworker;         list<object> args = (list<object>)e.argument;         var url = (string)args[0];        webrequest request = webrequest.create(url);        request.timeout = 300;         try        {            webresponse response = request.getresponse();            console.writeline("request successful.");        }        catch (exception ex)        {            console.writeline("request timed out.");        }    } 

webbrowser component should use when want embed instance of ie presentation layer. unless need this, can use more lightwweight.
