communicate with each other. objects that comply with the COM specifications are also called COM objects. According to COM, objects can be written in any language and communicate with the outside world through interfaces. An interface refers to a group of specific function calls (methods) provided by an object. Each object can have multiple interfaces, and diffe

In my daily work, I have seen many COM codes written by different developers. I was amazed by the many creative ways of working with COM, and some of the clever code that made COM work might not even have occurred to Microsoft. Also, seeing some mistakes repeated again and again made me frustrated. Many of these errors are related to thread and security, and this

functions are used to simulate the access to the variable of the year-old member. For example, setvisible can be used to set the visibility of a window. Getvisible can obtain this attribute. If (piwindows-> getvisible () = false) Piwindows-> setvisible (true ); It is not ideal for VB to use set and get. In VB, the following calls If window. Visible = false then Window.

Kaixinnet (kaixin001.com) is an SNS service that I often use. It uses a popular lamp combination, at the same time, its Alexa ranks around 134 (the actual data may be slightly different from this). Out of curiosity, I used curl to read a header and crawled the header three times, I found a cookie named serverid in the header, and each time the value is different, three are _ srv101-121 _, _ srv101-142 _ and _ srv134-47 _, in addition, the cookie name

Clause 3: select a smart pointer based on functions and implementation principlesThere are many types of smart pointers. The implementation principles can be divided into two categories: ownership-based transfer and reference-based counting. The built-in std: auto_ptr in C ++ is a smart pointer based on ownership transfer. Shared_ptr In the Boost library is a smart pointer based on the reference technology (currently it has become part of C ++ 0x [6 ). For example, the "ownership-based transfer"

Stream object is very similar to a separate disk file, it is also a basic object of data read and write operations, the use of streaming objects can save various types of data, it has its own access rights and a separate search pointer.

In PHP 4.2.0 to 4.2.3, external DLLs can be called using the W32api_register_function function, provided that the extended Php_w32api.dll needs to be opened in php.ini. If you are using PHP 5, the calling DLL only uses the COM class of PHP. The basic method is: $obj = new COM ("Server.object") It is clear that the COM class has improved PHP functionality by a lar
