Read HTML and manage frames in webbrowser control

Attached is a function that will return an HtmlElement object for the specified ID or Name in your document regardless of what frame it is in. 

An example of usage, assuming you have a webbrowser control named wb1 and are wanting to set an input field on a page where the input field has an id of "Last_Name", is as follows:
    HtmlElement el = getElement(wb1.Document, "Last_Name","id");
    if (el != null)
        el.SetAttribute("value","yourlastname");

The function will return null if the element is not found.  The type parameter can be either "id" or "name" referring to if we are looking for the id or name tags of the element.  If there are multiple elements with the same name and you are searching by name this will only return the last value.  The code could be easily modified to change that.

Hope this helps,

Here's the Function:
        private HtmlElement getElement(HtmlDocument doc, string id, string type)
        {
            HtmlElement el = doc.All[id];
            if (type == "id")
            {
                el = doc.GetElementById(id);
                if (el == null)
                {
                    if (doc.Window.Frames.Count > 0)
                    {
                        for (int i = 0; i < doc.Window.Frames.Count; i++)
                        {
                            HtmlDocument tmpDoc = doc.Window.Frames[i].Document;
                            if (tmpDoc.GetElementById(id) != null)
                            {
                                el = tmpDoc.GetElementById(id);
                            }
                        }
                    }
                }
            }

            if (type == "name")
            {
                el = doc.All[id];
                if (el == null)
                {
                    if (doc.Window.Frames.Count > 0)
                    {
                        for (int i = 0; i < doc.Window.Frames.Count; i++)
                        {
                            HtmlDocument tmpDoc = wb1.Document.Window.Frames[i].Document;
                            HtmlElementCollection coll = tmpDoc.All.GetElementsByName(id);
                            if (coll != null && coll.Count > 0)
                            {
                                el = coll[0];
                            }
                        }
                    }
                }
            }
            return el;

I have tried with this:
webBrowser1.Document.Window.Frames[x]
But haven't find any way to make it work.
Does anyone got an idea?
