How to programatically click or invoke a javascript method using System.Windows.Forms.WebBrowser?

Question

I tried with no success:

webBrowser1.Document.ExecCommand("alert('Hello World!')", true, null);

also tried:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    webBrowser1.Document.InvokeScript("alert('Hello World!')");
}

The correct way is:

private void webBrowser1_DocumentCompleted(object sender
    , WebBrowserDocumentCompletedEventArgs e)
{
    webBrowser1.Document.InvokeScript("alert", new object[] { "Hello World!" });
}

Using InvokeScript you can only call functions already defined on page.
