Remember when a friend wanted his VFP program to run this way: There is no VFP main screen (_screen), the runtime directly on the desktop, a login dialog box, enter the user name and password and verify the software after the main interface, looks like the software written in VB, a very cool feeling. The main interface of VFP software can usually be implemented in two ways: the main screen (_screen) or the top-level form (or the parent-child form). You can use the top level form to implement th

This example applies to the knowledge of the Between...and clause in the SELECT statement, referring to the SELECT statement: Select SQL command or the SQL language tutorial. This example runs the following diagram: This example uses the "Data 1" database "People information table", about the database is already looking at the case of VFP: sample database is

The concept of a single case pattern A single example pattern is a design pattern in which a class has only one object instance in the entire application. Specifically, as an object creation, the singleton pattern ensures that a class has only one instance, and instantiates it itself and provides this instance to the entire system globally. Instead of creating an instance copy, it returns a reference to an instance stored within a singleton class. C

Transferred from: http://aigo.iteye.com/blog/2301010Although the official Doc says that the event binding method is exactly the same as multi-cast usage, there are many examples on the Multi-cast forum, but the actual is different. And there is no such example on the forum. Later looked at the next Runtime/core source, the event of the binging manner as follows (attached complete steps):1, first define the custom event, in this case we define in Gamem

1. Define A singleton pattern ensures that a class has only one instance, and instantiates it and provides this instance to the entire system globally. Instead of creating an instance copy, it returns a reference to an instance stored within a singleton class. 2. Solve the problem/use scenario In the case of database applications, a single example pattern can be used to avoid the resources consumed by a large number of new operations.If you need a cla

PHP file read operations involve more PHP file manipulation functions than file writes, which are described in detail in code instances. The way in which data is stored in a text file is mainly three steps and some file operation functions are as follows: 1, open the file (file operation function: fopen)2, file data read (File operation function: fgets, file, ReadFile, feof, etc.)3, close the file (file operation function: fclose) The following is still a PHP file read and write operation cod

The implementation methods are as follows: The implementation method of search sort in Yii Cgridview Association table A little complicated, today I saw a foreigner wrote a game, I would like to tidy up and share with you friends, I believe it will be helpful to the study of YII framework.

different factory method patterns. In other literatures, simple factories are often discussed as a special case of the common factory model.Learning a simple factory model is a good preparation for learning the factory method pattern, and a good preparation for learning other patterns, especially the single case pattern and multiple example patterns. 2. Introduction of Simple Factory model For example, t

The business logic of CodeIgniter Controller is analyzed in this paper. Share to everyone for your reference, specific as follows: The previous analysis of the public controller by module distribution, to facilitate the control of specific modules, and the specific implementation of the class is placed in the library. Is it appropriate to put it in the library? And where is the more business logic in the controller? First of all, the understanding of several folders in CI Helpers, Libraries:

different library. $DB 1 = $this->load->database (' Default ', TRUE); $DB 2 = $this->load->database (' Test ', TRUE); But this way need to use when the initiative to load, not very convenient, we can be implemented in the My_model constructor, the return of the $DB1 to the Ci_controller of a property, and assign the property or clone to $this->db, For example: Public function __construct ($group _name = ') { parent::__constru
