The main idea is to invoke the Win32 API. 1. Introducing namespaces Using System.Runtime.InteropServices; 2. Declaration (Turn a WIN32 API function into a C # function) 　//声明INI文件的写操作函数 WritePrivateProfileString() 　[DllImport("kernel32")]

C # has a number of commands called preprocessor directives. These commands are never translated into commands in executable code, but affect all aspects of the compilation process. For example, a preprocessor can prevent a compiler from compiling a

Recently doing a thing to use to dynamically allocate IP and release IP. It's easy to implement in C + +. However, because the network IP settings are related to hardware, C # is not a ready-made interface call. The bridge can only be provided to us

In Windows Explorer, you can right-click on the DVD/CD Optical drive icon, select Eject to open the drive compartment door, and you may also find that there is no "close" command on the menu to turn off the optical drive. Next, let us use the

Construction and deconstruction of objects * * * In general, we would place the object as far as possible near the program section where it was used, which would save unnecessary objects from being manipulated and destroyed. Global Objects * * *

In C #, text can be displayed through label controls, TextBox controls, forms, and PictureBox controls, and forms and PictureBox controls are implemented primarily through the DrawString method. TextBox controls and label controls are designed to

Queues are linear tables that allow only inserts at one end and deletions at the other end. is an advanced first-out linear table (FIFO). The one end allowed to be inserted is called a team tail, which allows the deletion of one end to be called the

Not only can WMI get the computer data it wants, but it can also be used for remote control. Remote control of computers is not only the dream of hackers, also most network managers are eager to get, especially in modern networks, every network

Structural patterns (structural pattern) describe how a class or object can be combined to form a larger structure. The structure pattern describes two different things: a class and an instance of a class. According to this point, the structure

DirectoryComparison of instances between classes and structsThe difference between class and structureHow to select a structure or class one. Example comparison of classes and structs: Structure

The visual| Quick Start method exists to be invoked! Use the method name to invoke a method that requires it to perform its task. If the method is to get information (specified by its arguments), it must provide the information it needs. If the

Reflection of exceptions, expressions, and empty In the previous installment, I introduced the innovative way in which the next generation of Java language was used to eliminate the flashy things and complexities in the Java language. In this

Today, when writing code, you encounter a problem: How do I get "/images/job_logo.gif" from the string "Http://job.cnblogs.com/images/job_logo.gif"? The solution to this problem requires: 1. Only the APIs in the. NET class library can be invoked;

Constructors and destructors are two types of functions that seem to be simpler in a class, but there are always some unexpected errors in the actual application process. This paper will introduce the principle of constructor function and destructor

Introduction The operation of the screen is the general operation of control, but due to the inherent reasons of the screen itself, there are some problems, such as: high cost, easy to damage, difficult to repair and so on. So the computer virtual

Const is a regular customer when we write C + + code, and for those objects that we don't want to modify, it's best to use the const modifier. 1. Let's take a look at some idiomatic methods: 1　char　greeting[]　=　"Hello"; 2　char*　p　=　greeting;　　　　　　　

A. C # file operations provided by The difference between the file class and the FileInfo class. The main difference between the two is that file cannot be instantiated, only static methods are provided, and the latter can be instantiated, and the
