This is the last article in the series "approaching COM Interop" and the most involved technical points. I hope you can understand the description, and it is inevitable that there will be errors. Please kindly advise me. Back to the beginning, I started to introduce how to import a COM component through programming and generate the corresponding. Net Assembly. In fact, the process is very simple. I persona

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,

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
