First create a Web page: function messageBox(message) { alert(message); } II. Building Windows applications

Example 1: Look directly at the code provided by MicrosoftusingSystem;usingSystem.Threading; Public classexample{ Public Static voidMain () {//Queue the task.ThreadPool.QueueUserWorkItem (NewWaitCallback (ThreadProc)); Console.WriteLine ("Main

First look at common inheritance:classinstrument{ Public: voidPlay ()Const{cout"instrument: Lay:p"Endl; }};classWind: Publicinstrument{ Public: voidPlay ()Const{cout"Wind : Lay:p"Endl; }}; Instrument* Instrumentobj =Newinstrument ();

1. Multithreading Basic ConceptsProcess: All the resources that a program consumes when it runs. A process can consist of multiple threads.Threads: A unit of execution in a process that can share resources in a process.Multithreading: A program has

The purpose of this exercise is to use LINQ to XML, regular expressions, to practice using serialization and deserialization on this basis tomorrow, and continue to add a little bit of functionality.First, this is a form program, designed as follows:

 C # Delegation's understanding and basic learningDelegate, delegation, is a very important concept in C #, using delegates to enable programmers to encapsulate a method reference within a delegate object. You can then pass the delegate object to

The principle of printing is to generate MDI files that are automatically processed when the system touches the MDI. So, no matter what template, what way; in PrintPage event processing, generate a picture to print the content is OK!C #

Recently in a C # build Word functionality, called Microsoft's own COM components.  After the build has found a Winword.exe cannot shut down, debug or modify the code is not understood. Forced to close the process.system.diagnostics.process[] Myps;

1. Delegation overviewThis is a new concept, but its nature is not a novelty, and a delegate is essentially a class. Only the general class is a collection of data, and the delegate holds one or more methods. Delegates are reference types , so

In front of the delegation, the next thing to say about the incident, at the same time, finally say the difference between the Commission and the event.Events are similar to delegates, and events appear to be simplified for special-purpose delegates.
