conventions (ExtJS given the object-oriented type system is also imperfect), as well as some code specifications. These problems, in fact, can be solved from the perspective of language, tools, but we have to manually contract, manual inspection! Although EXTJS4 generally solves the problem of object-oriented design. But because of the difficulty of refactoring, writing inefficient, resulting in the first version of Rafy.js only wrote thousands of lines, it has been felt that maintenance is ver

Notebook keyboard can not be typed mainly four kinds of reasons, the following small series of four kinds of situation, specific causes and corresponding solutions to introduce the following: In the first case: Laptop keyboard failure Sometimes, we press the keyboard, there will be a lot of messy letters or numbers. It may be that one of the keys is pressed down, and there's no reason to bounce. We can also try to restart the computer to eliminate t

Tags: SQLite comparisons are different based on different values, not depending on the field type, because SQLite is a weakly typed field --------------------------------------------------http ://www.sqlite.com.cn/mysqlite/5/127.html In version SQLite3.0, the value is defined why the type is only related to the value itself, has no relation to the column, and is not related to the variable. (This is sometimes referred to as a weak type.) All other d

Label: recently, there is a need to write some C # programs, useful to dataset datasets and SQLite database, because I have never been good at remembering the syntax of various programming languages, so after reviewing a bunch of data, left the following content memo: First, sqlite operation, direct code, very simple://Create a database file stringDatasource=application.startuppath +"\\test.db"; System.Data.SQLite.SQLiteConnection.CreateFile

A dataset, also known as a data set, data set, or data set, is a collection composed of data. A Data Set (or dataset) is a collection of data, usually in the form of tables.
