We routinely clear IE history, all through IE's "Tools" menu, and click "Internet Options", there will be an Internet Options Settings dialog box. Click "Erase History" with the mouse, and click "OK" button. But using this method does not really erase all of IE's history completely. If you need to completely clear IE history, we can store IE history of the entire folder inside the contents of empty, natura

Erase and vectorerase used in vector As a result of a previous misunderstanding of vector found in the use of the latest project, we found that we do not know much about vect, so we want to write a bit about it.Attention in vector usage. In this article, we will first talk about the erase function of vector. If there is any error, please point outFirst, I wrote a function to print the vector memory and prin

Sometimes there is a less common requirement: deleting all projects that meet certain conditions from a map has nothing to do with the map key. For example, a map storing the student roster has the key as the student ID (INT) and the value as the name (string). It is easy to delete the map by student ID, however, if you need to delete all the students with the "Zhang" name in the map, you can only traverse it and compare them one by one. Using namespace STD; Below is the obviousError Method : /

Type Erase code fragment oneNew arraylistnew arraylist= = C2); /* outputtrue */Obviously in the normal use, ArrayList and new ArrayList is completely different types, but here, the program does indeed output true .This is caused by the type erasure of Java generics, because either ArrayList or new ArrayList both of the compilers are erased by the compiler ArrayList . Why did the compiler do it? The reason is the same as most Java's annoying point-comp

The following tutorial will teach all Linux users how to safely erase available hard drive (HDD), solid state drive (SSD), and USB flash drive space, so that no one can restore the deleted files. Have you noticed that when you delete a file from the system or permanently delete it from the recycle bin, it will disappear in the file system, but the file does not actually disappear, it resides in the available space of your disk drive and can still be r

java Generic erase :What is a generic wipe?First look at what generics are. My personal understanding: Because the collection can store arbitrary types of objects. However, once the object type stored in the collection is determined, it is not possible to store other types of objects, otherwise the compilation will not error. However, classcastexception exceptions are thrown when executed. To solve this problem, introduce generics, specifying the type

The actual deletion element in the C + + vector uses the std::vector::erase () method in the container Vecrot.Std::remove () in C + + does not delete the element because the container's size () does not change, only the replacement of the element.1.std::vector::erase ()Function prototype: Iterator erase (iterator position); Delete the specified elementIterator

When vector loops are removed, erase (IT) returns the address of the next iterator, and the insurance practice is to assign it to the IT it= erase (IT) This is caused by the vector's internal mechanism, so pay special attention to whether the iterator will fail when the vector is erase! Map can be directly erase (it+

Erase statement Reinitialize elements of a fixed-size array and release the storage space of the dynamic array. EraseArray ArrayThe parameter is the name of the array variable to be cleared. Description It is important to determine whether an array is a fixed-length array (regular) or a dynamic array, becauseEraseYou must perform different operations based on the array type.EraseYou do not need to restore memory for an array of fixed sizes.Erase

Containers in STL are divided into two types by storage method: containers stored in arrays (such as vector and deque), and containers stored in discontinuous nodes (such: list, set, map ). When using the erase method to delete elements, pay attention to some issues. When using list, set, or map traversal to delete some elements, you can use the following method: correct method 1 STD: List list; STD: List ::

=qvariant=[%This type is equivalent to the object in Java, which encapsulates most of the data types provided by QT and acts as a data type "erase". For example, if our table cell can be a string or an int or a color value, how can so many types return? As a result, QT provides this qvariant type, you can put many of these types are stored in the need to use a series of to function to take out. For example, if you wrap int as a qvariant, use the Qvari

Jquery.eraser is a plugin that uses mouse or touch actions to erase images, this plugin replaces the target image with an interactive canvas that can be erased using touch or mouse input. You can specify a callback function to complete and set the brush size. This effect is a little bit iOS above the eraser application, this plugin uses the image or canvas element but you have to make sure that the picture is loaded after full load call eraser (), ot
