How to extract WordPad Document object from Word document 2003

I tried to come up with a solution for this... I created a small app with one form containing a RichTextBox control named "rtbrichTextBox1".  This is quick and crude, but it works:

            Word.Application wdApp = new Microsoft.Office.Interop.Word.ApplicationClass();
            Word.Document doc = wdApp.Documents.Open(...);
            Word.InlineShape wpadDoc = doc.InlineShapes[0]; // or wherever your rtf doc is
            wpadDoc.Select();
            wdApp.Selection.Copy();
            this.rtbrichTextBox1.Paste();
            this.rtbrichTextBox1.SaveFile("YOUR SAVE FILEPATH HERE");
            Clipboard.Clear();  // to prevent Word from alerting you about clipboard data when it quits

It copies the embedded object to the clipboard and then pastes it into the form's richtextbox.  Then it uses the savefile method of the richtextbox to save a copy of the rtf.

There may be a better solution using reflection.  For example:

Type wordpadDocType = Type.GetTypeFromProgID("WordPad.Document.1");

This will get the type information for WordPad document objects.
