What I really write about today is the topic of Office task panes. Office 2003 calls them action panes. Office 2007 and 2010 call them custom task panes. At Add-in Express , they are known as Advanced Task Panes. What are they?
They are custom .NET forms you can embed in the top, bottom, left, or right, sections of supported Office applications (e.g. Excel, Word, and PowerPoint). Add-in Express 2010, like all previous versions, allow you to do more than is possible with Visual Studio out-of-the-box. In this video, I explain the Advanced Task Pane features provided by Add-in Express 2010 and then I provide a demo that shows how to build them and then how to control via code.
