title: SaveAs vs SaveAs2 in the Microsoft Office Word object model
body: <p>It looks like <a href="http://msdn.microsoft.com/en-us/library/microsoft.office.tools.word.document.saveas.aspx" rel="noreferrer">SaveAs</a> has gone away in Office 2010 in favor of <a href="http://msdn.microsoft.com/en-us/library/microsoft.office.tools.word.document.saveas2.aspx" rel="noreferrer">SaveAs2</a>. What is going on here? Are there any important differences between the two? My fix has been to check for SaveAs2 first, and then fall back to SaveAs. Is this reasonable?</p>
