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

First, let's introduce event bubbling and event capture. The processing mechanism for events in the browser defaults to event bubbling, for example #div1 { width:500px;height:500px; Background:rgb (12,42,31); } #div2 { width:450px;height:450px; Background:rgb (212,142,1); } #div3 { width:350px;height:350px; Background:rgb (1,242,153); } Bind Click event: Div1.onclick=function () { alert ("Div1") } div2.onclick=function () { alert ("Div2"

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

To the photographic enthusiasts for detailed analysis to share the Canon D30 video photography and supported video format. Analytical sharing: Video Shoot Canon D30 supports video capture, supports the highest 1920x1080/30p format video, and also supports 120fps, 240fps slow motion video shooting. Video format Canon D30 Support MOV, H.264, MPEG-4, AVC and other video formats. Well, the above information is small set to al

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 the previous chapter we practiced a streams synchronization of a single table, it looks very simple is not (if you feel complex, it is not because the streams itself is complex, but to configure the streams earlier preparation is more complex), in fact it is very simple, from small to see big, We should also see from the example above that streams's operation is capturing (capture)-> propagation (propagation)-> application, whether it's a table, a
