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

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.

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)
