With local storage and session storage, simple object persistence can be achieved, with simple key-value pairs or objects stored. However, when dealing with more complex relational data, it is necessary to use Web SQL database. browser support for Web SQL databaseFirst, how to use the Web SQL DatabaseResults in Google and data in Web sql:Second, asynchronous databaseUse the Window.opendatabase () method to create a local database connection or to establish a connection to a database that already

(Testentity! =NULL) {testentity["Statecode"] =NewOptionsetvalue (1); testentity["StatusCode"] =NewOptionsetvalue (2); } crmsvc_online.update (testentity);Of course, now the system only reconstructs a few APIs, I believe that with the follow-up with the new, the system will be more convenient development experience for the vast number of developers. The following is an API that already supports an entity lev

1. The idea of generics generics are a security mechanism that occurs after JDK1.5. JDK5 previously, objects that were saved to the collection would lose their attributes, and often the programmer would have to manually cast the type when taken out, which would inevitably raise some security issues with the program. For example: ArrayList list = Newarraylist (); List.add ("abc"); Integer num = (integer) list.get (0); Error at run time (string cannot

not change the original display order; You can use the DataView object, which only changes the in-memory data sorting; does not change the data source;C. Set the AllowSorting property of the DataGrid control to true; set the SortExpression of DataGridColumn to display ProductName using "ProductName DESC" ; bind a DataGrid control to a DataTable object;D, set the Displayexpression property of the DataTable object to be: Bind the DataGrid control to the DataTable object;Note: The Sort property: G

Easyasp finally to v2.2, is still improving the handbook, the group has a lot of people ask how to use the problem, so it is intended to write a manual at the same time to write some new features introduced to facilitate the use of easp children's shoes quickly into the state. To tell the truth, see so many people still write ASP, still support easp, feel very rare, so also has not dropped the development of easp, or hope that easp can give the last a

rarely used in the most recent period of time, the likelihood of being used in the future is also very small, and The purpose of this algorithm is straightforward to understand that when the cached content needs to be updated and is already full, Quickly find and replace content that is used as often as the lowest number of times in the current entire cache. LRU (least recently used): Most recent unused algorithm, The idea and principle is If a data is in the last is not accesse

represent the storage location of the first element in a linear table. In the sequential storage structure, the storage location of the I-th element AI is LOC (AI) = LOC (AI) + (I-1) × L L indicates the space occupied by each element in the table. Based on the calculation relationship, you can randomly access any element in the table. A linear table adopts a sequential storage structure. It can randomly retrieve elements in the table.

, you can access this information in the created ZipArchive object. This information can be used for various purposes, such as checking the size of the decompressed file or creating a list of ZIP files without opening it. Some features of php zip allow very useful methods to process these file structures. In the next example, we will show you several ways to view these features and learn how to create a ZIP file structure when creating a ZIP file.Continue compression Let's take a look at an exam
