Display word file with formatted contents in .aspx page

Hello Friends,
 I want to display my word file contents in .aspx page. After displaying them i want to select some part of the word file and do some formatting on that selected text. I have tried the following code. It gives me all the text of the word file on the page but without formatting.
        oWordAppl = New Word.Application
        oDoc = oWordAppl.Documents.Open("c:\test.doc", missing, oReadOnly, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing)

        oDoc.ActiveWindow.Selection.WholeStory()
        oDoc.ActiveWindow.Selection.Copy()
        FreeTextBox1.Text = oDoc.Content.Text
        Label1.Text = oDoc.Content.Text
   & ...
