C# tricky - callback functions like Adobe Acrobat

Hi All,

I have a tricky problem where I'm getting a word template and then replacing the tags with those from a dataset. That part is fine but running around 300 of these and it's incredibly slow. So I thought maybe it'd be possible to do each one at a time and show the user as much as possible. Now this is guessing!! so any clue as to how to do this with code if you can would be very much appreciated....

Thanks, Tim
