Post to a fan page using Webbrowser

Question

I’m making an application to post on my fan pages, already log in, list the fan pages, it’s all right.

I’m just not getting to put the text in the facebook text box.

Look here:

<div data-block="true" data-offset-key="72l55-0-0" class="_209g _2vxa">
<span data-offset-key="72l55-0-0">
    <span data-text="true">Preciso colocar o texto aqui!!!</span>
</span>

HtmlElementCollection items = webBrowser1.Document.GetElementsByTagName("div");
foreach (HtmlElement item in items)
{
    if (item.GetAttribute("classname") == "_209g _2vxa")
    {
        item.InnerText = "oiii " + DateTime.Now;
        item.InvokeMember("click");
        //SendKeys.Send("{ENTER}");
    }
}
