Windows Server has further developed the Active Directory (Active Directory) on the basis of Windows NT Server 4.0. The Active Directory is started from a data store. It uses a data store similar to the Exchange server, known as: Extensible Storage

One, abstract class: Abstract classes are special classes, but cannot be instantiated; In addition, there are other attributes of the class; It is important that abstract classes can include abstract methods, which are not possible for ordinary

The window API functions can be invoked in C # through the interoperability service using System.Runtime.InteropServices. And by attributes to specify the location of API functions, and how to invoke, for example, We're going to call the function in

The throw statement is used to emit a signal that an anomalous condition (exception) occurs during program execution. Throw statements are often used in conjunction with Try-catch or try-finally statements. You can use the throw statement to

Recently looked at the previous learning C # contact code, inadvertently found a very interesting project. Is the effect of a fluttering form, after running the program, the current screen will be like snowflakes fluttering a lot of custom icons,

There is an example of how to find a field in a table that is somewhere in a given collection. SQL is simple to write, for example: Select * from table where ID in (2,3, 4, 5). is to look for the value of the ID field within this given set (2,3, 4, 5

First of all, the principle of the use of Socket Interface network communication, here to the most commonly used C/s mode as an example, first of all, the server has a process (or multiple processes) at the specified port waiting for customers to

Bo Master this time to write some C program code, because before the C is not a lot of understanding, it encountered a lot of bottlenecks, of course, there are many interesting methods can be used to solve these problems, the following problem is

A typedef declaration, called a TypeDef, creates a new name for an existing type. For example, people often use T ypedef to write more beautiful and readable code. The so-called aesthetics, meaning that the typedef can hide clumsy syntax constructs

Recently I spent some time learning how to write Add-in for Visual C + + 6.0. This is an interesting question, but overall, documentation and sample procedures are still scarce (more rare in Chinese). So I decided to write out some of my own

In the previous article "AjaxControlToolkit environment with JavaScript to achieve a simple DropDownList" wrote about the use of JavaScript written in a DropDownList example, because it is not easy to reuse and in C # management, So later, using

Android is built on Linux on the OS, when it comes to security, network protocols, file encryption and other functions, often need to call the underlying API in C language to implement, and how to send instructions to the C side to perform the

Two, Putchar (), Getch (), Getche (), and GetChar () functions 1. Putchar () function Putchar () function is to output a character to a standard output device in the form of: Putchar (CH); Where Ch is a character variable or constant. The

2.3 Character type (char)With different modifiers, you can define both signed and unsigned character type variables, such as:Char A:/*A is defined as a signed character variable * *unsigned char l; /*l is defined as unsigned character variable *

The new automated Deterministic resource recovery (Automatic deterministic destruction) in C++/CLI is considered an excellent design. Is the use of the so-called C++/CLI this "new bottle" to install Bjarne Stroustrup proposed raii this "old wine."

Second, the pointer variable of multidimensional array After the two-dimensional array A is decomposed into one-dimensional array a[0],a[1],a[2], p is set to a pointer variable that points to a two-dimensional array. can be defined as: Int (*p) [4]

Variables can be stored in the form of "static storage" and "Dynamic storage". A static storage variable is usually a storage unit that is set when the variable is defined and remains unchanged until the entire program ends. The global variables

For anyone unfamiliar with design patterns, a brief overview of the field may leave the impression that design patterns are a big marketing scam, a simple programming technique, or just a plaything of computer scientists. While these impressions

1.3.4.2 Continue statement The function of the continue statement is to skip the remaining statements in the loop and enforce the next loop. The continue statement is used only in a for, while, Do-while, and so on, and is often used in conjunction

In the previous MailMessage save as a eml file (c#+smtpclient), we used the Reflection (Reflection) method to invoke the System.Net.Mail internal object Mailwriter implemented the MailMessage is saved as a eml file. Through the last implementation,
