With the System.IO.Compression class added to the. Net Framework 2.0 for compressing/decompressing files (GZipStream methods), let's look at a simple example. Code1: 1 public static void Compress (String filePath, String zippath)2 {3 FileStream sourcefile = File.openread (FilePath);4 FileStream destinationfile = File.create (Zippath);5 byte[] buffer = new Byte[sourcefile.length];6 GZipStream zip = null;7

compression : Removes all comments, tick marks, line breaks, and useless spaces in Javascript code, compressing the JS file size.How JavaScript files are compressedThe first, of course, is to remove the comment .The other is the same as the CSS compression to remove line breaks , spaces or something.JavaScript has several variable forms, such as variables, function names, function parameters, and so on, usually when we write JS code, in order to facil

Today, we have encountered the problem that IIS 7 cannot compress js files. In IIS 7, static content compression has been enabled, but access in the browser has not taken effect. I remember that I had encountered this problem before and didn't think of a solution... Later, I remembered that the. js settings in the default MIME Types of IIS 7 were incorrect.

Asp.net uses RAR for File compression and decompression Author: qingyueer Home page:Http://blog.csdn.net/21aspnet/Time: 2007.6.13 If the RAR program is installed on the server, Asp.net can call RAR to compress and decompress files. However, it should be noted that the web program cannot directly call the client program (unless ActiveX is used, ActiveX is almost deprecated ), therefore, to decompress a local

When working on a project, I need to compress and decompress the file. I was so patient that I finally found a way to study it. The two classes for File compression and decompression are rewritten for their own needs, namely ZipClass and UnZipClass. After encountering a lot of difficulties, I decided to write the program for compression and decompression, and I must paste the source code for sharing, so that the first contact with compression and deco

Generally, steps 4 and 6 are not recommended. Steps 4 are not secure and may damage the database or cause data loss. If the log reaches the upper limit in step 1, subsequent database processing will fail and the log can be restored after being cleared. 　　1. Clear logs Dump transaction database name WITH NO_LOG 　　2. truncate transaction logs Backup log database name WITH NO_LOG 　　3. Shrink database files (Without compression, the database file will not

Mtime file content Last modifiedThe time that the Atime file was read or accessedCTime File Status Change timeThe meaning of Mtime and atime is easy to understand, and ctime needs more explanations. Because the inode maintains the metadata on each file, the Inode data also changes if the file-related metadata changes. This can be caused by a series of actions, including creating symbolic links to files, changing file permissions, or moving
