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
Problem Description:The program has been working normally, today the computer re-made the system, and then began to appear this problem: "The given port name does not start with com/com or resolves to a valid serial port." Serial debugging assistant is also not used. Serial cable is not a problem, it is not a hardware problem, the program is not a problem (normal operation on other computers).Exception info

With smart pointers, you may not want to manually release or increase the reference count. In this case, please refer to the following functions:

XPCOMAs a component technology implemented by Microsoft, the component development technology COM in Linux plays an important role in the Windows platform and can be seen in module reuse and cross-language communication. But today I want to introduce the com implementation in Linux ---- XPCOM, which is the basic technology used in the Mozilla Browser project. We can use C ++ to create the XPCOM component, i

First, the preface
COM component objects are completely different from. NET class objects, but to make a COM client call a. NET object like a COM component, the. NET program
Like to use. NET objects using COM
is COM technology out of date? That's not true either. Technically, it is true that COM usage is declining, but intellectually, the idea of COM's interface-oriented is being carried forward by Java and. Net. So we still need to deal with COM. It depends on the area of your work. Although now Microsoft's platform is slowly toward. Net migration,
The. NET Framework reusable software is not a new concept. For eight of years, people have been using various forms of Component object models (COM). It turns out that it is the most successful reusable software model. COM introduces the concept of "component"-a reusable block of code that can be combined to combine the functions of multiple independent functions to extend to applications such as Microsoft
