Why is sometimes WebBrowser.Dispose() launching Internet Explorer?

Question

When I do the following (Actually I repeat the same whole code with different web pages):

        Navigator nav;
        nav = new Navigator();
        nav.B         


        

Answer 1

Make your Navigator form look like this:

public partial class Navigator : Form {
    private bool done;

    public Navigator() {
        InitializeComponent();
        Browser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(Browser_DocumentCompleted);
    }
    void Browser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) {
        if (e.Url == Browser.Url) done = true;
    }
    public bool Completed {
        get { return done; }
    }
}

And your loop like this:

        Navigator nav;
        nav = new Navigator();
        nav.Browser.Navigate("http://www.amazon.com/gp/search/ref=sr_adv_b/?search-alias=stripbooks&unfiltered=1&field-keywords=&field-author=&field-title=&field-isbn=0471848573+&field-publisher=&node=&field-p_n_condition-type=&field-feature_browse-bin=&field-binding_browse-bin=&field-subject=&field-language=&field-dateop=&field-datemod=&field-dateyear=&sort=relevanceexprank&Adv-Srch-Books-Submit.x=18&Adv-Srch-Books-Submit.y=4"); //        http://msn.com"); //stackoverflow.com/questions/3661536/while-true-application-doevents-doesnt-know-when-the-program-finishes");
        this.Enabled = false;
        while (!nav.Completed) Application.DoEvents();
        this.Enabled = true;
        nav.Dispose();
