Writing from a windows form to microsoft word 2007 using VSTO
In this post I would like how easy it is to use Visual Studio Tools for Office. If you have never heard before of VSTO just google it. In a few words it is a component of Visual Studio(since Visual Studio 2005) that provides a robust, .NET-based environment for building business applications using classic Office programs like Word and Excel. So that means you do not have to learn the specific Office object models, and of course you do need VBA anymore.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=dotnetstories.wordpress.com&blog=1661705&post=751&subd=dotnetstories&ref=&feed=1" />
