The “Show SharePoint Version in Office Documents” solution can be used to extract version information stored in Microsoft SharePoint Foundation 2010 and Microsoft SharePoint Server 2010 document libraries and display it within Microsoft Office documents (a version for Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 is also available in the Downloads area).
It comprises of two components:
• A site collection feature to deploy four new custom site columns for use in Content Types or document libraries where version information is to be shown in Office documents.
• A site feature which implements an event receiver to populate the custom columns with version information for any document library present in the site, including the current version, when the document was last approved, who approved it, and when it was approved.
Once the custom column information is being populated by the event receiver, it can be shown in Office documents using the Quick Parts (Office 2010 and 2007) or Fields (Office 2003) features.
The 2010 release utilises the new sandbox features introduced in SharePoint 2010, which allows site collection administrators to deploy solutions into their sites, preventing the need to install the solution directly onto SharePoint servers by a farm administrator.
