Aimed at more experienced developers who need to get the old and new in Windows to coexist, COM and giving. NET Interoperability you all the ins and outs of detail to get the Framework. NET code and the older COM standard to work together effectively. Material in the late-binding mimics. NET is also prominent here, because this technique is not clear under the new Windows. At the heart of this book are six chapters show how to obtain. NET to call COM code and vice versa, organized into beginning, intermediate, and advanced techniques for each. When it comes to calling NET code. Of the older COM code, apart from the basics of calling NET in C "traditional" + + and Visual Basic., The authors also show how to "consume" new. NET classes like collections within COM. Final sections turn to the other COM + services, with a full tour of transactions and just-in-time activation (JITA) to build more scalable Windows components. (Here, in addition to "classic" COM + component in C + +, the author shows how to do it in. NET.) Round out this book with examples of "full service" component of Windows on the NET,. Includes solid samples using Web services. While COM is destined to wither away, for the next few years there will be ample opportunity for advanced programmers to take advantage of in-depth knowledge on top of COM and NET -.. Richard Dragan Topics covered: Introduction to Platform Invocation (PInvoke) services; traditional DLL calls from C and C + +; use PInvoke to call a traditional DLL with.
