Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置 串口属性的实例. 在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口 进行通信.串口通信方便易行,应用广泛. 一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是 半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点. 每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正 确的命令后作出应答. (Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

（利用GIF_LZW算法实现的）网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由：稳定性好。 二、使用字节数据流进行传输，理由： A:VB的String存在自动Unicode转换问题，影响速度； B:可以直接发送8位字节数据，不需要使用Base64编码，从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由： A:行程编码、Huffman压缩算法压缩率太低； B:JPEG压缩算法需要太多位运算，且运算量大（有专门MMX优化算法），不利于VB实现； C:GIF-LZW压缩算法压缩率较好，且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由：“有序抖动”处理的结果具有一定规律性，有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX spe

大家都认为，c语言之所以强大，以及其自由性，很大部分体现在其灵活的指针运用上。因此，说指针是c语言的灵魂，一点都不为过。同时，这种说法也让很多人产生误解，似乎只有C语言的指针才能算指针。basic不支持指针，在此不论。其实，pascal语言本身也是支持指针的。从最初的pascal发展至今的object pascal，可以说在指针运用上，丝毫不会逊色于c语言的指针。(Everyone thinks, c language were strong, as well as its freedom, it is reflected in its most flexible use of the pointer. Therefore, said pointer is c language of the soul, can not be overemphasized. At the same time, this argument also let a lot of people misunderstand, it seems that only the C language can be considered a pointer to pointer. basic does not support pointers in this matter. In fact, pascal language itself is also supported by the pointer. Pascal far from the initial development of the object pascal, can be said that the use of the pointer, and in no way inferior to the c language pointer.)
