rsync multiple threads

I was planning to analyze the page in the event, but after half a day, I did not call the processing function, and the search was solved, I would like to thank the original author, webbroswer control navigate, for generating a page before obtaining WB. htmldocument then analyzes the elements and labels of htmldocument. In fact, the collection does not only collect a single page. In the main form, the collection can be completed. For example, if you collect several list pages and have more than N

Use invoke to solve control access errors between multiple threadsFrom http://doudou232102.blog.163.com/blog/static/92981066200952782429613/ On a winform interface, there is a button (button1) and a text box (textbox1). Create a New thread in the click event handler of button1, you are expected to change the textbox1 value in the new thread. The error-prone code is as follows:// Click the event handler button Private void button#click (Object sender,

The operation progress must be displayed when a long operation is executed. This can be done using multiple threads.1 define a thread operation class threadclassClass has an attribute field to save the operation status, there is a method for the thread to call2. instantiate this class in Asp.net processing, save the class in the session, create a new thread using the method in the class, and start the threa

This article Reprinted from: http://blog.csdn.net/wtz1985/article/details/301637 In the previous article, I have already elaborated on the Implementation of simple locks in multiple threads. At the end of the article, I raised the question that when inserting a chain table, the query operation cannot be implemented if it is just a simple lock. So the "recursive lock" emerged in the world. Some people may s

Author: Sun Dongfeng) Java provides a lot of convenience for programmers because it supports multiple threads. In fact, it also supports multi-thread programming in iphone development, and it is no more troublesome than java. In this article, I will take the classic "multi-thread Ticket System" in most Java tutorials as an example to implement the same in the iphone. The following is the java version of t

1. Use the synchronized keyword. Synchronized(Anobject ){Value = map. Get (key );} Ii. Use the locks provided by JDK (Java. util. Concurrent. locks. Lock ). Lock. Lock ();Value = map. Get (key );Lock. Unlock (); 3. Use the read/write lock (Java. util. Concurrent. locks. readwritelock) provided by jdk1.5 ). Rwlock. readlock (). Lock ();Value = map. Get (key );Rwlock. readlock (). Unlock (); In this way, the two read operations can be performed simultaneously, and the theoretical efficiency

If a thread already exists in a synchronized method of the same object, other threads must wait until the thread ends before entering the method. So what happens if a class has multiple synchronized methods? See the following code: Public class test { The running result is as follows: Test2 called Obviously, when the Synchronized Method Test2 of the object T2 is called by the thread TT, the main thread can

In the comments, I is told that I should avoid thread.sleep (), all right, let's try this:1. You could wrap the Parallel.ForEach within a task and manually add your Completedcallback () Public Task Doworkasync (doworkcompletedcallback completedcallback) { return Task.Factory.StartNew ( { Parallel.ForEach //callcallback manually Completedcallback (); });}2. Use ContinueWithTask.Factory.StartNew ( { //do work } ). ContinueWith (completedcallback);3

The app encountered this problem when the user clicked on a tag, using an asynchronous task to open a child thread to request data from the server and refresh the display.But inevitably there are users like to play, and hard point, as programmers, we have to tolerate users. Therefore, we use the mechanism of delayed message, if the user clicks on the last click of the delay time, that the previous message has not been issued, and a message sent to handler, we can remove the previous message.The
