Derek,

see if this blog posting by Rick Strahl is helpful, I seem to remember that he describes the same scenario as you do. http://www.west-wind.com/weblog/posts/2005/Jan/13/Embedding-Microsoft-Word-as-a-control-into-Desktop-Forms

>I'm using the Web Browser OleControlt to embed a Word document on my form. However, when I invoke:

>loBrower.Navigate("C:\TestDocument.doc")

>Rather than the dcoument appearing in the control on my form, Word is opened externally and appears in its own window, and from within my OleControl I simply see "Navigation to the webpage was cancelled". The OleControl itself works, I've tested it with a standard URL and that's fine.
