{"product_id":"9781449308681","title":"Learning DCOM","description":"\u003cp\u003eDCOM -- the Distributed Component Object Model -- is a recent upgrade of a time-honored and well-tested technology promoted by Microsoft for distributed object programming. Now that components are playing a larger and larger part in Windows 98, Windows NT 4.0, and Windows 2000, every Windows programmer will want to understand the technology. DCOM competes with CORBA as a rich and robust method for creating expandable and flexible components, allowing you to plug in new parts conveniently and upgrade without the need for code changes to every program that uses your component.This book introduces C++ programmers to DCOM and gives them the basic tools they need to write secure, maintainable programs. While using Visual C++ development tools and wizards where appropriate, the author never leaves the results up to magic. The C++ code used to create distributed components and the communications exchanged between systems and objects are described at a level where the reader understands their significance and can use the insights for such tasks as debugging and improving  performance.The first few chapters explain both the remote procedure calls that underlie DCOM's communication and the way DCOM uses C++ classes. Readers become firmly grounded in the relation between components, classes, and objects, the ways objects are created and destroyed, how clients find servers, and the basics of security and threading.After giving you a grounding in how DCOM works, this book introduces you  to the Microsoft tools that make it all easy. By showing what really  happens each time you choose a button in a wizard, \u003ci\u003eLearning DCOM\u003c\/i\u003e makes it possible for you to choose what you need.This book is for anyone who wants to understand DCOM. While thoroughly practical in its goals, it doesn't stint on the background you need to make your programs safe, efficient, and easy to maintain.Topics include:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMIDL (Microsoft Interface Definition Language, the language for defining COM interfaces)\u003c\/li\u003e\n\u003cli\u003eCOM error and exception handling\u003c\/li\u003e\n\u003cli\u003eCustom, dispatch, and dual interfaces\u003c\/li\u003e\n\u003cli\u003eStandard and custom factories\u003c\/li\u003e\n\u003cli\u003eManagement of in-process versus out-of-process servers\u003c\/li\u003e\n\u003cli\u003eDistributed memory management\u003c\/li\u003e\n\u003cli\u003ePragmatic explanation of the DCOM wire protocol\u003c\/li\u003e\n\u003cli\u003eStandard, custom, handler, and automation marshaling \u003c\/li\u003e\n\u003cli\u003eMultithreading and apartments\u003c\/li\u003e\n\u003cli\u003eSecurity at the system configuration and programming level\u003c\/li\u003e\n\u003cli\u003eActive Template Library (ATL), ATL wizards -- and what they don't do\u003c\/li\u003e\n\u003cli\u003eWriting a component that can be invoked from Visual Basic\u003c\/li\u003e\n\u003cli\u003eTechniques for using distributed components\u003c\/li\u003e\n\u003cli\u003eCreating an ActiveX control and embedding it in a Web client\u003c\/li\u003e\n\u003cli\u003eAuthentication and the use of Windows NT security features\u003c\/li\u003e\n\u003cli\u003eTechniques for merging marshaling code\u003c\/li\u003e\n\u003cli\u003eConnection and distributed events management\u003c\/li\u003e\n\u003cli\u003eAn introduction to COM+ features\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"O'Reilly Media, Incorporated","offers":[{"title":"Default Title","offer_id":47128391123184,"sku":"9781449308681","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781449308681_p0.jpg?v=1763830854","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781449308681","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
