erase cache

To the users of Baidu map software to detailed analysis to share the way to clear the cache. Method Sharing: 1, open the system settings, pull to the lower part, open the Application management (MIUI version in the tutorial for example, please choose your mobile phone similar options, such as many mobile phones will not be system applications and general applications separate) 2, in the list slowly down, find "Baidu map" 3, d

For files deleted on your computer, normally, if you don't have a special deal, the system simply deletes the file name in the Files allocation table, and the real data is still on disk. With some data recovery software, it's easy to recover files that have been called deleted. The partition assistant has the ability to erase the disk, it can completely delete the data on the disk, so that the data on the disk can not be erased or deleted by other da

// Use erase to clear the content in the vector and set respectively # include Fnset will delete all the elements in the set, but fnvec will cause the program to crash.The reason is that when fnvec calls Vec. Erase (t), the elements behind t slide forward, and the iterator pointing to these elements is also affected. In fnset, if erase is called, the elements do

To the U.S. Mito software users to detailed analysis to share the use of the elimination of the pen tutorial. Tutorial Sharing: Well, the above information is a small series to the United States and Mito of this software users brought to the detailed use of the elimination of the pen to share the full content of the tutorial, you see the users here are now very clear about the use of the method, the elimination of the pen can erase the p

Failure phenomenon: Lenovo Security Bulletin: LEN-9458 Potential impact: After running the Security cleanup utility, it is possible to recover drive data. Severity: Medium Impact Range: Lenovo-specific products Summary description: The Toshiba firmware used to clear the data on the following SSD does not conform to the Lenovo specification and is now determined to run the ThinkPad Drive

In most cases, our website uses a database as a container for storing site data. When you execute an SQL query, the typical process is: connect to the database-> prepare an SQL query-> send a query to the database-> get the database return result-> close the database connection. However, some data in the database is completely static or infrequently changed. The cache system caches the SQL query results to a faster storage system for storage, this avo

ATA Secure EraseThis procedure describes how to use the hdparm command to issue a Secure Erase ATA instruction to a target storage device. When a Secure Erase was issued against a SSD drive all its cells would be marked as empty, restoring it to factory default Write performance.DISCLAIMER: This would erase all your data, and is not being recoverable by even data

The performance of the project has been at the lower-and lower-level and has been exploring. Since the WCF segment was optimized in the past few weeks, the speed has improved significantly. HoweverProgramIt is not an ideal requirement, so we must continue to work hard! I. Situation Some time ago, we found that multiple clients frequently obtain the same data when they connect to the server for the first time. That is to say, each client needs to search for the same data in the database, it i

data. For example, a 8-bit nor flash, assuming a capacity of 4 byte. The chip should have 8 data signals d7-d0 and 2 address signals, a1-a0. Address 0x0 corresponds to the No. 0 byte, the address 0x1 corresponds to 1BYTE, the address 0x2 corresponds to the 2nd byte, and the address 0x3 corresponds to the 3rd byte. To a 16-bit NOR flash chip, or working in 16-bit mode, an address corresponds to a half-word (16-bit) data. For example, a piece of 16-bit NOR FLASH, assuming that it has a capacity o

The difference of map::erase function in different versions of STL 1. c++98 and C++11 standardshttp://www.cplusplus.com/reference/map/map/erase/ 2.PJ STL (Windows) map::erase function (C++11 standard) returns a map::iterator: iterator Map::erase(const_iterator _where); iterator Map::

The function of the erase is to invalidate the iterator as a parameter and return the iterator that points to the next parameter of the iterator.As follows: Copy Code code as follows: List Particlesystem; List::iterator pointer; if (Pointer->dead = = True) { pointer = particlesystem.erase (pointer); } There is a program about using erase incorrectly. Copy Code code as

For the following code: 　　 my_container.erase(iter); My_container is a container of STL, and ITER is an iterator pointing to an element in the container. If it is not in the for, while loop, There is no problem in deleting elements in this way. If you are performing m_container iteration in for and while, deleting all elements that meet the conditions may cause problems. If m_iner iner is iterated in for and while, deleting all elements that meet the conditions may cause proble

Http://blog.sina.com.cn/s/blog_67b6b720010114d3.html The erase () function is used to delete elements in a container.Delete an element in a container: C. Erase (t );It seems like a simple action. However, different types of containers are completely different internally, which will be introduced later. Suppose there is a question that deletes all elements in a container that meet the condition n = x. Accord

The Remove and erase functions in C + + STL used to confuse me and delete, what's the difference between the two?The action of remove in a vector is to place an element equal to value at the tail of the vector, but does not reduce the size of the vectorThe role of erase in vectors is to remove elements from a position position or section (begin, end), reducing their sizeThe Remove member function in the lis

Clear application Data and uninstall apps, execute commands directly:* String cmd = "pm Clear" + PackageName; or * String cmd = "pm Clear" + PackageName + "here";* String cmd = "PM Uninstall" + PackageName; or * String cmd = "PM Uninstall" + PackageName + "here";* String cmd = "pm Install" + Apk_path; or * String cmd = "PM Uninstall" + apk_path+ "here";and the service and alarm timing of the application itself is automatically canceled after the data is clear, and the process ends, and so can al

STL Notes (4) About Erase,removeThe elements you want to erase are easy to identify. They are elements of the original interval starting from the "New logical end point" of the interval to the end of the interval true. To get rid of those elements, all you have to do is invoke the interval form of the erase with those two iterators (see clause 5). Because the rem

The erase function is prototyped as follows:(1) string erase (size_t pos = 0, size_t n = NPOs);(2) Iterator erase (iterator position);(3) Iterator erase (iterator first, iterator last);That means there are three ways to use:(1) Erase (pos,n); Deleting n characters starting f
