Microsoft® Visual Studio® 2010 Unleashed

Creating an Office Document Extension

There are various ways to customize Office documents themselves. You can host controls in a document, create action panes specific to a document, implement your own smart tags, and store data within a document.

A document-level project is created using the same process we used for add-ins. This time, however, you select an Excel 2007 Workbook or Word 2007 Document project type. These project types use designers that represent the look and feel of an Excel workbook or a Word document.
