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.

Here's a look at setting up and managing user accounts.
The computer account is described later. Consider first that the purpose of establishing a domain is not ultimately for account management. Implement its functions by managing accounts.

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

Because traditional COM technologies use static unmanaged programming, and. NET uses dynamic managed programming, this topic essentially discusses a special case of interoperability between managed and unmanaged code. The current. NET v2.0 provides the following three types of interoperabi

We know that C # development efficiency is very high, especially for some beautiful pages. if you want to develop a desktop application with better performance and page highlights, you can use C ++ and C # together. now that NetFramework is integrated in Windows 7, you don't have to worry about installing a C # application and then installing the entire NetFramework. you can use C # To make a com component, and then C ++ calls it. the opposite is true
1. coinitialize, coinitialzeex coinitialize and coinitializeex are all windows APIs. They mainly tell windows how to create COM objects for programs. The reason is that the program calls com library functions (except cogetmalloc and memory allocation functions) you must initialize the com library before.

.
the usage of ccomptr is almost the same as that of common com pointers. Note the following when using ccomptr.
1. ccomptr ensures that addref and release are called correctly. Therefore, you do not need to call addref and release.

Overviewis COM technology out of date? This sentence is neither right nor wrong. 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.

When defining an interface, the logical name that follows the keyword interface is called the interface. If no GUID is introduced, this logical name is the unique identifier of the interface. As shown in chapter 1, this logical name string is used when the runtime query object (dynamic_cast) is used.
When twoProgramEach member independently develops an interface. In a given common problem domain, the two interfaces are not completely defined. The a
COM component development can use vb c # VC ++ and other individuals to be familiar with C #, but C # controls have a huge disadvantage, requiring customers to install the framework, which is quite difficult, of course, VB also needs to install the Runtime Library. VC ++ can be installed or not installed. It depends on your compilation. In other words, the VC Runtime Library is relatively lightweight and acceptable. So I plan to spend some time organi
The progress may be too fast, and the previous chapter is not very well grasped. When I was reading Chapter 10th, I felt that many knowledge points were not clear, and the structure of this chapter was not clear before, it can be said that it is a bit confusing. Review can help you better understand the previous content. Here, the key point is to thoroughly repeat the textbook code and understand how to write the code.
The code in this chapter is also an old problem. The author of this book does
