Hello All-

I wrote a ASP.NET web service for automating Word document creation
based on WordML templates. I have this all working using Word Interop's
Find and Replace funtionality to replace my placeholder text from the
template document with the actual data from my database.

We were hoping to increase performance by using Bookmarks to mark the
range fo the placeholders... I found this article on MSDN which make it
seem very straight forward and perfect for what we want:
<a
href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_wrcore/html/
wrtskhowtoupdatebookmarktext.asp">How
to Update Bookmark Text</a>

I actually copied and pasted the exact final method from the article to
use in my code. When I called the method (after confirming with
Document.Bookmarks.Exists( bookmarkname ) that the bookmark exists), I
get a "Server threw an exception" exception on the line "rng.Text =
newText", noted below:

internal void BookMarkReplaceRange(string bookmarkName, string newText)

{
   object missingValue = Type.Missing;
   object oBookmarkName = bookmarkName;
   Word.Range rng = ThisDocument.Bookmarks.get_Item(
       ref oBookmarkName).Range;
   rng.Text = newText; //Error here
   object oRng = rng;
   ThisDocument.Bookmarks.Add(bookmarkName, ref oRng);
}

This is the error:
System.Runtime.InteropServices.COMException (0x80010105): The server
threw an exception.
at Microsoft.Office.Interop.Word.Range.set_Text(String prop)
....

Anyone know why this MSDN code sample isnt working?

Why is the error so vague?

*cries* How do i make it work?...

Thanks inadvance!
