Question

I have one method. You can even test it:

 private readonly 
    public HtmlDocument Browse()
    {
        var _browser = new WebBrowser();
        var link = "http://hotline.ua/sr/?q=allo";
        var loadFinished = false;

        _browser.DocumentCompleted += delegate { loadFinished = true; };
        try
        {
            _browser.Navigate(link);
        }
        catch (Exception xx)
        {
            if (!(xx is UriFormatException))
                throw;

            loadFinished = false;
        }

        while ( ! loadFinished  )
            Thread.Sleep(50);

        loadFinished = false;

        return _browser.Document;
    }

Then somewhere in code I call this method:

var doc = Browse();

Instead of getting a HtmlDocument I get to the infinite loop in :

 while ( ! loadFinished  )
            Thread.Sleep(50);

It seems that DocumentCompleted is never fired. But in Web browser I can easily to get this page.
Anybody knows why ? And what should I do to get a HtmlDocument ?

Answer 1

Oh sorry. I found a solution, after I post this topic:

That the reason why this event not fired:

I should not use

Thread.Sleep(50);

Because the event fired earlier and freed resourses. So thread get killed before it hits the document completed method.

If I change for:

Application.DoEvents();

It becomes work perfectly.

Thanks for you replies also !
