In fact, this method is inherently unscientific. DCOM itself is a form of COM, but since we hear that com generally treats it as a locally executed COM, DCOM, of course, is the Distributed COM, which is executed on another computer on the network. the Difference and connection between

The original:multithreaded model of COMCOM's multithreaded model is one of the most incomprehensible parts of COM technology, and many books are involved but not well understood. Many new people will feel very confused here, Google God can search for an article on the vckbase, but the personal advice is not to look good almost nonsense in the mess.COM does not actually have any multithreaded models, so the multithreaded model he uses is still the set

Python calls the C # Com dll component, Previously, the company had a set of C # AES encryption and decryption solutions, but the solution uses the Rijndael class for encryption, rather than the four AES models (ECB, CBC, CFB, OFB, these four types Use the RijndaelManaged class. In Python, the Crypto library AES only has these four modes. In this case, the C # AES Rijndael class encryption effect cannot be achieved in Python. Similar to the functions

When it comes to managing Linux servers, there are many different ways to do this: Keyboard + monitor, Web Landing, web-based tools, graphics tools under X system, and so on, which is not a problem on a regular

Chapter 4 components 1. com, the component object model, is a standard on how to build components and how to build applications through components.2. Advantages of components: applications can develop and change over time, custom applications, Component Libraries, and distributed components.3. Requirements for components: components must be dynamically connected; internal implementation details must be hidden.4. the

A typical scenario in COM is to have the client object instantiate the server object and then invoke the objects. However, without a special mechanism, these server objects will be difficult to turn to and callback to client objects. COM Connection points provide this special mechanism to achieve two-way communication between the server and the client. With connection points, the server can invoke clients w
