Webbrowser and html input text without "post"

I have a webbrowser and a system.windows.forms.button (not an html button).
I want to read the text from input objects, like a basic textbox for a name, in an html document but without it having to be "post"ed.

here's an example of the html doc loaded into the browser

Notice there is no submit button on the form.

Someone would fill in their name and a line of their address then click a System.Windows.Forms.Button
Here is my code (which doesn't work as I expected it to)

foreach(HtmlElement elt in browser.Document.Forms)
{
foreach(HtmlElement ch in elt.GetElementsByTagName("INPUT"))
{
MessageBox.Show(ch.Name + " Text = " + ch.InnerText);}
}

I was expecting it would show the text that was typed in but I keep getting a blank return.

Any help would be great!

Thanks!

For anyone else out there, the code I used was
C#
public form1()
{
InitializeComponent();

// Make the form the scripting object
browser.ObjectForScripting = this;

// Display the html file file.html
browser.Navigate(Application.StartupPath + "\\file.html");

}

void Button1Click(object sender, EventArgs e)
{
foreach(HtmlElement elt in browser.Document.Forms)
{
foreach(HtmlElement child in elt.GetElementsByTagName("INPUT"))
{
browser.Document.InvokeScript("SendTypedText", new object[] { child.Name });
}
}
}

public void ShowText(string ibox_name, string ibox_value)
{
MessageBox.Show(ibox_name + " = " + ibox_value);
//Of course now you can do whatever you need to do with the data
}

//file.html code

Thanks!
