Part One

This will be the first in a short series of articles to show how we use Open XML.

Open XML is a Microsoft format which can be used to programmatically create Word documents.

Below is a code example and associated output.

I have not shown all the code examples yet  as these will be explained in future blogs.

The code shown constructs a page containing a header and footer, a document heading, some normal text a table and a watermark. Styling has been applied to all these elements.

I have created separate classes and methods to encapsulate the commonly used code, otherwise the code becomes inflated and unreadable.
