PHP Object-Oriented Programming and reflection API details, object-oriented reflection This article describes PHP Object-Oriented Programming and reflection APIs. We will share this with you for your reference. The details are as follows: Understanding class Class_exists Get_class check the instanceof class of the object to verify whether the object belongs to a

through a process called "dynamic linking" with the Windows interface.Each Windows EXE file contains the various dynamic-link libraries it uses and the reference addresses of the functions in the library.When a Windows program is loaded into memory, the function calls in the program are parsed by a pointer to the DLL function entry, and the called functions are loaded into memory.When linking Windows programs to survive executables, be sure to link to the special "import library" provided by yo

Software development we often have to access the database, access to data, has been put forward to let the chicken peck rice to talk about database programming knowledge, this article explains in detail how to use the MySQL C language API for database programming.

Review passive development In C # programming and development of game controllers-API (1) This article introduces the development of "passive mode. In this way, our program acts as only one message receiver. The system regularly tells us the current status of a game controller. After receiving the gamepad, our program can process it as needed. However, if you are a careful person, you will find that there w

), then the operating system must take advantage of the system provided to the user's "special Interface"-system calls the user process into the kernel space of the detailed location. When making system calls. The program execution space needs to enter the kernel space from the user space.Return to user space after processing is complete. The system calls mentioned earlier do not interact directly with the program ape. It's just a soft interrupt mechanism that submits a request to the kernel to

The user uses the function CreateFile () to create a connection to the specified serial port.File, you can then use the file handle returned by the function to stringPort parameter settings.01 HANDLE Hmodem; Defining a serial port handleHmodem=createfile ("COM1", generic_read| generic_write,0,0,03 open_existing,file_flag_overlapped,0); Associative stringsPort and returns its handleThen use Getcommstate () to get the current COM1 DCBAppropriate modification of DCD, the function can be calledSetCo

toPostQuitMessage ()the value, here you can ignore it, fromWinMain ()The return value will be used in the exit code for the end of the process. Focus : Getmessgae () will return 1 If there is an error, be sure to remember this, or at some point you will have a sore egg ... Even if GetMessage () is defined to return a Boolean value, it can also return a value other than TRUE or FALSE , because BOOL is defined using a UINT(unsigned int). The following code example may work, but the condition wil

Some time ago spent 38 yuan from the Internet to buy a pair of North pass USB game handle, so the weekend and evening leisure time can play when the boy's SFC and arcade simulation game. One day on a website to play a flash game, suddenly thought, if you can also use the handle to play flash games, it should be more fun. But unfortunately, the current flash is not supported on the game to program the handle, which is unavoidable in flash a regret. Although the flash does not support the game h

Serial Data acquisitionThis document describes how to obtain the serial port raw data and parse the raw data into data that can be processed or displayed.First, the serial port collection has many ways:1), MFC has a special control, direct programming acquisition, a control can only collect a serial port, and the serial port name such as COM20 may not open (here I do not practice, senior to say so), the baud rate is too high reading will be wrong.2),

Therefore, early colleagues really gave them DB link stringsThe customer's Windows programs and websites are connected to our compan

The project I was working on needed to use the Subversion feature. I posted this article on Tianya, and I will repeat it here today. When I configure the header files and dependent libraries required for compiling subversion, the compilation can be passed, but there is always a problem with the link. At that time, I wanted to find a guide document on subversion client API programming. It was very difficult.
