Thanks Paul how have you been? long time no talk too! Paul you got me thinking about the fact that my new Visual Studio Express setup may not be compatible, so i put in a try catch around that routine and got the following exception:
Exception:Exception:System.MissingMethodException: Method not found: 'System.Type System.Runtime.InteropServices.Marshal.GetTypeFrom CLSID(System.Guid)'.
And when i googled it, it mentioned a possible versioning difference, so when i changed the Visual Studio version number back to to 4.0 from 4.5 its now working!

And Paul, i just wanted to mention that the reason i'm converting WORD documents to TXT, is mainly to build a cross reference to fields that are in the WORD documents and even though i can't specifically hyperlink to a specific word value location in the document, i can know if a specific word value is in a particular WORD document and when i jump to the beginning of the document, i can then use that bookmark/hyperlink tool you helped me build which is working pretty good now!
