Input: Consider Input: If You've Decided to use VSTO, an Excellent Place to Start . VSTO (pronounced Visto) is a most interesting product when viewed from Microsoft's overall standpoint. It is a very carefully crafted product with the primary purpose of continuing Microsoft's continued dominance of the desktop marketplace, and a part of Microsoft's thrust to move more heavily into the server marketplace.      As best I can tell, it works something like this. Microsoft recognizes that servers handling up web pages, processing mail, etc. are a huge market, but that Linnux owns a big percentage of that market. Consequently Microsoft came up with the .NET strategy. .NET is a bunch of subroutines (if you will) that are written to provides all kinds of utility to programmers. You write your applications using propriatary programming languages such as C# and J# that use the .NET library and consequently have to run on Microsoft operating systems.     In the Office environment, packages such as OpenOffice have gotten to be pretty good, are basically Microsoft compatible so you don't have a re-training problem, and are FREE. I don't know how much success OpenOffice has had, but it appears to be enough to attract Microsoft's attention.     Enter VSTO. VSTO adds customization and productivity to Microsoft Office applications through 'links' that tie Office to the .NET framework. So to use VSTO first you must have and load the .NET framework, then you must load Visual Studio.NET - in that order -- then install Visual Studio 2005 Tools for Office.     All of this is clearly explained by Mr. Bruney in this book, who then goes on to do an excellent job of explaing how to write programs using VSTO. As examples he includes some real world applications. Most of the book is on Excel applications, but Word and Outlook are included as well. Finally he concludes the book with an excellent discussion on pivot tables.     Conclusion: A well written, understandable and complete book on VSTO. If you're going to be using VSTO, this is an excellent place to start

Output: POS


Input: Consider Input: Not worth the $$ . Extremely basic! It would be useful to have on hand, but the $ is way too much for the few quick tips the book offers

Output: NEG


Input: Consider Input: Nothing new and bad photos . I agree with the above review; minimal information, absolutely horrible photos and rather crummy quality paper makes this book not worth buying.  Meadmore selected many chairs that are discussed much more completely in other similar books.    He missed a few key chairs of note; Saarinen's Grasshopper chair and Aalto's Armchair 400 (Zebra or tank) chair.    If you want a good welll rounded selection of Modern Chairs, I'd suggest the 1000 Chairs book instead


Output: NEG
