Re: Controlling IE, submitting forms

I made a Windows Form app that invokes a Spell checker when the Browser control is browsing certain webpages and I enter comments , like on a discussion board.  It watches for when I leave the text box in the webpage and then does the spell check. This doesn't directly answer your question, but you can see how I reference forms and elements.


So the first thing I do is scan a new web page after it loads:

private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
        {
            

                if (this.webBrowser1.Document != null)
                {
                    this.htmlDoc = this.webBrowser1.Document;  // HtmlDocument
                    if (this.htmlDoc != null)
                    {
                        if (this.htmlDoc.Forms["commentform"] != null && this.htmlDoc.Forms["commentform"].Children != null)
                        {
                            HtmlElementCollection elCol = this.htmlDoc.Forms["commentform"].Children.GetElementsByName("comment");

                            webTextBox = this.htmlDoc.Forms["commentform"].Children["comment"];  // HtmlElement
                            if (webTextBox == null)
                            {
                                if (this.htmlDoc != null && this.htmlDoc.Forms.Count >= 2 && this.htmlDoc.Forms[1].Children.Count >= 6 && this.htmlDoc.Forms[1].Children[5].Children.Count >= 3)
                                {
                                    webTextBox = this.htmlDoc.Forms[1].Children[5].Children[2];
                                }
                            }
                            if (webTextBox != null)
                            {
                                webTextBox.KeyPress += new HtmlElementEventHandler(webTextBox_KeyPress);
                                webTextBox.LostFocus += new HtmlElementEventHandler(webTextBox_LostFocus);
                            }
                        }
                    }




        }

void webTextBox_LostFocus(object sender, HtmlElementEventArgs e)
        {

            if (!inFormTextEvent && !inWebTextEvent)
            {
                if (string.Compare(webTextBox.InnerText, richTextBox1.Text, StringComparison.Ordinal) != 0)
                {
                    try
                    {
                        inFormTextEvent = true;
                        inWebTextEvent = true;
                        this.richTextBox1.Text = this.webTextBox.InnerText;
                    }
                    finally
                    {
                        inFormTextEvent = false;
                        inWebTextEvent = false;
                    }


                }
                if (!string.IsNullOrEmpty(webTextBox.InnerText))
                {
                    if (DialogResult.OK == this.ultraSpellChecker1.ShowSpellCheckDialog(this.richTextBox1))
                    {

                    }
                }
            }


        }

THESE are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands by it now, deserves the love and thanks of man and woman. Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph.
