1. How to create COM objects Clients can create COM through the CoCreateInstance function, and must know some basic things about the object before it is created, such as the CLSID of the object or the ProgID of the object. Another object creation method is created by a moniker (moniker), which is the use of object naming and binding techniques (i.e., name technology). 2, the status of the name technology

But this is explained in Vc.net 2003 use method, even if you no longer use vc6.0, also please and the previous back of the content, reference comparison. 2, this first component, in addition to all COM components must be IUnknown interface, we implement a

in the "Big talk design mode C + + version-abstract Factory mode", we save the world attempted, leaving little regret, in this article we will give a solution--com component technology, but also pull the factory model in the application of COM component technology.The root cause of the Factory mode violation of the open-closed principle is that the object generat

Overview] This article starts with a basic concept, and clearly demonstrates COM in terms of COM interfaces, type libraries, GUIDs, and so on. At the same time, this article also introduces the creation of COM objects, what is MTS, how to use MTS to manage COM objects, his advantages and programmatic implementation, an

1.COM Technology Overview COM represents the Component Object model, the software development technology that Microsoft promotes. The application software developed by COM specification has the powerful function, mainly has the following several points: COM is a binary pro

COM Component Design and Application (1)Origin and composite FileAuthor: Instructor Yang I. Preface On a dark night in 1995 AD, one of my teachers said to me, "Xiao Yang, I will write programs in the future, just like building blocks. Hurry up and learn some ole technologies... ". At that time, I thought," Are you kidding me? How do I build blocks to write programs? In May 100 ...... ", but as a good studen

today is very good, fast, the structure is clear, the implementation is not complicated; the next book introduces the connection point mode (Support Connection Points), the connection point method is not very good, slow (if it is remote DCOM way, to choose it carefully), complex structure, The only benefit is that ATL wraps it up, so it's easier to implement. Not introduced and not, because Microsoft has a large number of support event components are implemented with connection points, cough ..
