I am the architect of a multitiers DCOM application which has got many exes and dlls. We need to expand the functionalities of this application with a new tiers that we are developping in .Net.
I thought this book - given its title - would help and answer some very specific questions such as:
- How can a server fire an event to one or more clients?
- How can a client pass an interface to the server so that the server can query back the client?
- How can you have several instances of a server or clients without ending up with a jungle of Tcp Channels to register and maintain?
- How do I communicate efficiently with a DCOM server/dll
- How to implement callbacks (the so called callback in the book are not callback but only the "OnTerminate" asynchronous delegate which concept is explained in any basic C# book).
None of these questions was answered in this book. You will find in the 250 pages of this book what a general .Net book summarizes in 30 pages or so. It is very disappointing.
This book is great at explaining the obvious and may be great for a real beginner who has never written any distributed application and who has no idea what a server and a client is. In this book these concepts are defined. That may help young developpers. But I am afraid to say that the professionals will not find the answer to any question they may have. Not a single one.
