How to get javasrcipt returnValue from webbrowser control (tinymce htmlcode fron webbrowser)

In my previous post about the htmlcontrol i have not explained how i communicate with the tinymce javascript to get the actual values from the textarea.

Here is it how it works...

string valueFromTinyMce;


IHTMLDocument2 htdoc2 = editor2.HTMLDocument2;
IHTMLWindow2 parentWindow = htdoc2.parentWindow;
if (parentWindow != null)
{
 IHTMLElement el = htdoc2.createElement("input");
 el.id = "myValue";
 ((IHTMLDOMNode)htdoc2.body).appendChild((IHTMLDOMNode)el);

 parentWindow.execScript("document.all['myValue'].value = tinyMCE.getContent('mce_editor_0')", "javascript");

 valueFromTinyMce = el.getAttribute("value", 0);
}
