Here we add an array to save the path information recstack [] that has already been asked by the queue. The visited [] array is the information of

In: http://blog.csdn.net/liyuefeilong/article/details/43927909, the edge detection is mainly discussed by using Sobel operator and Laplace transform. It mainly uses the method of thresholding the gradient size to obtain a two value edge image. In an image, the edges tend to contain important visual information because they depict the contours of the image elements. However, there are two major drawbacks to using only simple two-value edge images: Using this method to

Application of ICMP--tracerouteTraceroute is an important tool to detect the routing between host and destination hosts, and is also the most convenient tool. As mentioned earlier, although the Ping tool can also detect, however, because of the IP header limit, ping can not be fully recorded under the router. So the traceroute just fills this flaw.The principle of traceroute is very very interesting, it rec

This article mainly share with you the implementation of PHP to detect the current character encoding and transcoding methods, combined with text and code, hope to help everyone. First, detect the current string encoding and change the encoding to Utf-81 Gets the encoding of the current string$encode = mb_detect_encoding ($str, Array ("ASCII", ' UTF-8 ', "GB2312", "GBK", ' BIG5 '));2 change character encod

PHP generally uses file_exists () to determine whether a file or folder exists, and if the file or folder exists, returns True, False if it does not exist. Today, when implementing the file download function, it is found that the function cannot detect whether a file containing Chinese is present, and always returns false, in the case of a Web page using UTF8 encoding. The modification was long after the discovery because the full path was not encoded

Use JavaScript to detect browsers If you really need to check the browser type, it is easy to implement it using JavaScript. View Demo Download Source from GitHub JavaScript has a standard navigator object that contains information about browser usage. The navigator object consists of many attributes, but the userAgent Attribute-a string contains the browser, operating system, and all other information we need. To displaynavigator.userAgentYou on

Using badblocks to detect bad sectors of a hard disk is a consumable device. When used for a period of time, physical faults such as bad sectors may occur. If a bad track occurs on the hard disk of a computer, if it is not replaced or processed in time, the number of bad tracks will increase and cause frequent crashes and data loss. The best solution is to change the disk, but in the case of temporary, block sectors of Bad Sectors in time, do not touc

Browser Detection Method1. Object Feature Detection: a common method for determining browser capabilities. This method can be used if you are more concerned with the browser's capabilities and do not care about its actual identity. The common native Ajax write method uses this method to create XMLHttpRequest:Copy codeThe Code is as follows:IXHR: function (){If (window. ActiveXObject ){XHR = new ActiveXObject ('Microsoft. xmlhttp ');} Else if (window. XMLHttpRequest ){XHR = new XMLHttpRequest ();

First, if the application is stuck or because the memory is too large, it is usually used in instruments to detect. But for complex situations it may be necessary to use the way that child threads monitor the main thread, and I'll introduce these methods: Time ProfilerYou can look at ways in which the methods in multiple threads are too time consuming. Tick the right hide System libraries to filter the information. The call tree will then be sorted by

reference we're dealing with is a block, we can throw it in a fake struct to mimic block. After placing the struct in a C language, we can know the object that block holds. Unfortunately, we do not know whether these references are strong or weak references.To solve this problem, we used a black box technology. We create an object to impersonate the block we want to investigate. Because we know the interface of the block, we know where to find the reference that the block holds. The objects we

1. Build an AJAX development framework with the following code2. Write the JavaScript Custom function CheckName (); To detect whether the user name is empty, when the user name is not empty, call the Createrequest () method to send the request to detect whether the user name exists, the code is as follows:function CheckName () { var username = form1.user.value; if (username== "") { window.al

Zi Yue: Learning without thinking is not the case, thinking without learning is dangerous. In the previous article: the Egocache cache framework explained in detail that Egocache can set the cache expiration time by default of 1 days. Look at the Egocache source code, set the default time: [self setDefaultTimeoutInterval:86400]; //86400 = 24 * 60 * 60 刚好是一天时间。Egocache Why do I have to set the cache expiration time? Or what is the benefit of setting the cache expiration time? I think t

Printers is designed to control the printer, but when the printer is not installed, but will be prompted I/O error, so there must be a test to detect the existence of a printer, I tried many methods, but I/O error is always earlier than my judgment, so use the following bad recruit to detect the printer. You can detect the presence of a printer by first adding pr
