1, in the Millet mobile phone we find "settings" and then click to find "System settings" as shown in the following image. 2, after entering the Millet system settings application we found the "Advanced settings" will open a "detailed Setup interface" details as shown in the following figure. 3, then we in the System Advanced setup options, light a little bit "button" after entering the millet "key settings" in the following. 4, in the key settings, we find the "

A simple SQL statement: Select count (1) From tablename with (nolock) Where Columna = A and columnb = B and columnc = C, called by a key page, although memcache cache is added, due to data structure design problems, the CPU load of the database server is as high as 100%, and the critical page response times out, resulting in extremely bad impact. The reason is,Index missingAt the beginning of the data structure design, no index was created for the table, and then ignored that the table only tes

method One:1. As shown in the following figure, we are near the "Fn" + "F1" key on the keyboard of the notebook.2. A "Settings" window for the WIN8 system is then opened, as shown in the figure:3. Here we will see a "sound" option, click to enter as shown in the figure.4. Now we see a "Recording" tab on the right side of the "Sound" option to click on it.5. Here we go to the "recording volume", where you can zoom in and out of speed, Min is small, Max

When writing a program, we will use the following code to notify the sound to implement this behavior: Setvolumecontrolstream (audiomanager. stream_music );Mediaplayer = new mediaplayer ();Mediaplayer. setaudiostreamtype (audiomanager. stream_music );// Mediaplayer. setoncompletionlistener (beeplistener );Assetfiledescriptor file = getresources (). openrawresourcefd (R. Raw. Beep );Try {Mediaplayer. setdatasource (file. getfiledescriptor (), file. getstartoffset (),File. getlength ());File. Clos

About the remote snapshot copy Function Remote snapshot replication is a disaster recovery authorization function. This function asynchronously copies block-level data from volumes on the Local Storage System in batches) to volumes on the same system or different independent systems. Different systems can be located at the same site or different sites as the first system. The typical replication configuration involves the following physical and logical components: Host connected to the Local S

Abstract: The most common hard-to-decide problem that Linux users encounter when installing the Linux operating system is how to correctly evaluate the size of each partition to allocate suitable hard disk space. When a partition space is exhausted, the solution is usually to use a symbolic link or a tool to adjust the partition size (such as PatitionMagic), but this is only Abstract: The most common hard-to-decide problem that Linux users encounter when installing the Linux operating system is

When a partition space is exhausted, the solution is usually to use symbolic links, or to adjust the size of the partition tool (such as patitionmagic, etc.), but this is only a temporary solution, there is no fundam
