Note: I found this \"Creating a Word Doc in C#.NET\", but that is not what I want.
Do you know how to create a .odt to create file from C#
I found this one yesterday when looking for a way to create Spreadsheeets, it looks like creating writer files is quite similar: http://www.suite101.com/content/creating-an-openoffice-calc-document-with-c-a124112, dont forget to install the Open Office SDK from Oracle first.
Unfortunately I have not found a way to create a file without opening it yet.
