The knowledge points in this chapter are listed below, which are not sorted out and extended. 1. com interfaces are implemented using purely abstract base classes in C ++. a com component can provide multiple interfaces, A c ++ class can use multiple inheritance to implement a component that can provide multiple interfaces. 2. functions marked with _ stdcall will use the standard call Convention, that is,

There are many ways to set up your wallpaper, you can call SystemParametersInfo, modify the registry, and you can do so through the IActiveDesktop interface provided by the Windows shell. The IActiveDesktop interface is a COM interface that needs to be used in a way that calls COM components.This explains how COM is used by applying the IActiveDesktop interface.

1, the role of COM As a software model, COM provides the standard of communication between programs, but its greatest contribution lies in the change of programming method. COM combines both object technology and component technology. Object characteristics make application system design and implementation more in line with the face of the real world; Component

1. DCOM The process transparency of COM is manifested in the Component object and client program can have their own process space, can also share the same process space, COM is responsible for the customer's call to the Component object correctly, and ensure the correctness of the parameters passed. Component objects and client code do not need to consider the details of the invocation delivery, as long as
