Word OLE from C# WinForm ?

[james]

I have a .Net C# Winforms App with a RichTextBox
control and I want to provide an option for the user
to open the Rtf in Word, edit it in Word and get the
edited value back to my C# app Dynamically (DDE?)

Where should I start? Is there a document explaining this?
I ahve looked at msdn but I do not see exactly what I am
looking for

thanks,

JIM
