-oriented approach to the area of the circle, first to do an abstraction, what is called abstraction?Object-oriented is the real life of people or things to abstract, for example, I now ask for the area of the circle, first of all, I would like to define a "circle" such a custom data type, which is similar to the structure of C language, in note Four with the help of the structure of the C + + class.I define a "circle" class whose properties (member variables) are radius and area, and its behavi

Job is used in a lot of practical applications. Regular users perform certain functions, stored procedures, and so on. Here's a look at how to create and start a job.For example, a stored procedure is executed using a job schedule.Stored Procedure name: Pro_test_jobExecution interval: 2 hours,The SQL statements are as followsDeclare job number ; V_count number;begin SELECT Count (*) into v_count from user_jobs uj WHERE upper (uj.what) = UPPER (' pro_test_job; '); I

Entityframework learning notes -- 005-provide a correct explanation for code first, entitycodefirst In Microsoft's official introduction to ef7, ef7 will discard database first and model first, and only retain the use of code first. This has aroused a lot of concerns and concerns come from the incorrect understanding of code first. Because many people think that code first is the third method that distinguishes database first from model first. In fact

App->activity->custom Dialog Example using Activity to implement a custom dialog boxThe class customdialogactivity itself is nothing special. The key point is its definition in Androidmanifest.xml: android:label=" @string/activity_custom_dialog " Android:theme = "@style/theme.customdialog"> Customdialogactivity uses a custom Customdialog style (Theme). Android apps can use a custom interface style (Theme), Theme as a set of related style definitio

Once, the supervisor arranged for me to write a prototype of the project , but the tab control was involved in the project, and it was found in the controls in Axure without the tab control . So we can only do it in a different way, we use the Dynamic Panel to simulate.1. First we drag the dynamic panel to our page . As follows2. Double-click the dynamic paneland fill in the tab page you want to create3. Then click the fifth button below the panel status to edit all the controls4. Then pull a re

Due to the popularity of the JSON specification, the json.stringify is natively supported by browsers other than the low-

PHP can be used from time to time to get the contents of the CSV file, and sometimes it means that there will be a interval, and then you will find that some details may be forgotten. Then the degree Niang, Google, and then feel, gee, I again do the things that repeat. So we have to make this simple, but still occasionally need to check the information to record. The format in the CSV file is as follows: The PHP side code is as follows: $mapDept = Array (), $handle = fopen (dirname (__fi
