Why do I need a conversion operator? We know that for built-in types of data we can convert data by forcing the use of a translator, such as (int) 2.1f; a custom class is also a type, so objects in a custom class also need to support this operation

The design of library is is a compromise process. The ideal library should be short, fast, powerful, flexible, extensible, intuitive, universally applicable, with good support, without constraints, without errors. It's not there either. Libraries

Thread synchronization is the core of multithreaded programming, and its purpose is to correctly handle various problems of multithreading concurrency, such as thread waiting, mutual exclusion when multiple threads access the same data,

Several printing modes In two of Visio development, we often need to print documents, which is a normal requirement, and the document object of Visio provides the following print modes: Constant Value Description

If a member in a class is declared as static, the member is called a quiescent member. The members in the class are either static or non-static. Generally, static members belong to the class, and non-static members are instances of the class-objects.

An MDI (multiple-document interface) application means that a user can open several documents at the same time, and each document appears in a separate window in the client area of the main window of the application. Like word processor word is a

Often see some examples of VB directly with a CreateObject can invoke system functions (mostly COM objects), such as user settings, network settings and so on. Although C # can invoke the CreateObject function by using the method of the namespace of
