经usb红外口转为虚拟串口的小程序，并且附带有读取程序。-By infrared usb virtual serial port to a small program, and have read the attached program.

各种套接字接口函数都有其使用的上下文环境和参数规定。上下文环境由程序模式和程序流程决定；参数则有正确和错误之分。因此在根据错误提示信息解决错误时，应注意到这两种情况。-various socket interface function has its use in the context of environmental requirements and parameters. Environmental context by the procedures in decision processes and procedures; Parameters are right and wrong points. In accordance with the wrong message at the wrong solution, it should be noted that both cases.

这是一个简单的端口扫描程序 注：要在cmd中找到exe的绝对路径 然后按照格式 才能有运行。-This is a simple port scanner Note: To find the exe in cmd and then follow the format of the absolute path in order to have to run.

过直接控制DNS进程(其实也就是svchost.exe,不过对应用户名是NETWORK SERVICE)进行数据传输的例子.编程中出现了很多问题,比方说获取svchost对应用户名时没有权限(但是能够操作LOCAL SERVICE),在句柄值为0x2c时进行getsockname时会停止运行-DNS direct control over the process (that is, in fact, svchost.exe, but on the application name is NETWORK SERVICE) examples of data transmission. Programming in a lot of problems, for example, to obtain the application name svchost without permission (but able to operate LOCAL SERVICE), in the handle when the value of 0x2c will stop running getsockname
