Hi Basavaraj,

As far as I know there is no such book -- it would interest far too few
people to make the publication profitable.

The documentation, what there is of it, is mostly on the MSDN web site.
Start at http://msdn.microsoft.com/office/ and click the link to
"Understanding Office Development" in the left pane. The flyout menu will
lead you to articles about using Visual Studio to automate various Office
programs, including Word.

You'll find that most of the articles and code samples are in VB.Net and C#.
Usually you will have to do your own translation to C++, although
translating from C# to C++ shouldn't be very difficult.

The central idea is that, although you're using another language, you're
manipulating the same objects in the Word object model that are available in
VBA. This means you must be familiar with those objects, which are
documented in the VBA help; and you must understand how those object affect
Word documents -- something you must often discover by experimenting, as the
documentation doesn't cover a lot of the oddities.
