In practical development, in order to solve the problem of Ajax cross-domain requests, the target's Web API is requested and returned by a controller on the same domain at the server. To facilitate debugging of such requests, we want to be able to monitor these requests through Fiddler. Fiddler official gives the Java application How to configure: Configure a Java application to use Fiddler. But we found that if we use org.apache.http.impl.client.DefaultHttpClient, neither of the official method

JS Bubbles the event by default and begins capturing all of the listener objects for that event from the root element. We can specify whether the event executes in the bubbling or capturing phase by binding the event.
Obj.addeventlistener (Event,function () {},bool);
Bool:false, represents the bubbling phase execution
Bool:true, representing capture phase execution
Example:
For example, there are UL events and Li events, click on the event

In doing some questions about members online, we often want to judge whether the user is offline according to whether the browser is closed, and then remove the user from session and application.
Because browsers are stateless, there are two things that can happen when you capture a browser shutdown:
1. Real Close Browser (a. Click on the Close button B. Right-click the taskbar to close C. Press ALT+F4 to close)
2. Refresh the browser.
So how do yo
In the Android development will inevitably appear program crash, commonly known as crash. Random access to the user when the test unknown bugs caused by our program crash, at this time we can not get directly to the error log, can not fix the bug. This will greatly affect the user experience, at this time we need to register a function to capture the global exception information, when the program appears crash information, we log the error log, upload

Write your Own "IDE"--how to capture the standard output of a console program in real time in a graphical interface.
The IDE is the abbreviation for the Integrated development environment (integrated Development environment). There are a lot of good Ides, like JBuilder and Kylix, like Visual Studio. I do not know whether you have noticed that most of the IDE itself only provides code editing, engineering management, such as human-computer interaction
1. Fiddler Introduction
Fiddler is an HTTP protocol debugging agent tool written using C #. It supports numerous HTTP debugging tasks, can record and check all the HTTP communication between your computer and Internet, can set breakpoints, see all the "in and Out" Fiddler data (COOKIE,HTML,JS,CSS, etc.).
This article is fiddler introductory tutorial, mainly introduces fiddler download installation, HTTP interface packet capture analysis and simulatio
One of the tasks in common enterprise data Platform management is the constant obsession with SQL Server DBAs, which is monitoring data updates. Many data applications need to capture updates to the business data table. I have seen several solutions:
1, in the data table to add a special sign column;
2, by creating a trigger on the datasheet;
3, through Third-party products, such as Lumigent log Explorer.
In fact, both the 1th and 2nd schemes are
Transferred from: http://blog.csdn.net/baoqiangwang/article/details/5395874SQLSERVER2005 provides error handling mechanisms similar to exception handling in the C # and C + + languages.A Transact-SQL statement group can be included in a TRY block. If an error occurs inside a TRY block, control is passed to another group of statements contained in the CATCH block.The related error message is as follows:Error_number () returns the error number.Error_severity () returns the severity.Error_state ()
The AddEventListener () method can specify the "usecapture" parameter to set the delivery event type:false→ bubble true→ captures the default false. The inner element is the p tag, the outer element is the div tag, and the experiment is as follows:In bubbling, an inner element's event is first triggered before the outer element is triggered, in order: internal ==> ExternalCSS:. whb100{width:100px;height:100px;border:1px dotted red}.whb200{width:200px;height:200px;border:1px Dotted #2ea6df}.cente

In multimedia applications such as desktop video conferencing and videophone, obtaining digital videos is a key prerequisite. Before video for Windows (VFW) appeared, it was extremely complicated to capture digital videos. Microsoft Visual C ++ has been supporting video for Windows (VFW) Since version 4.0, which makes video capture programming very convenient. For multimedia application development, the mos
