自己用builder编写的点对点聊天软件，以后再也不用担心服务器忙咯，-use c++ builder,conect point to point.can chat in any time,should not care about the block server.

这篇文章后对于BCB开发人员来说，不仅可以对 FlashGet 等软件的开发原理有一定的了解，特别是在开发组件方面也有很大的指导作用，请耐心的将它看完。很简单-this article for the BCB after the developers, not only to FlashGet software development tenets of a certain understanding, especially in the development of components are also great role in guiding, patient reading it. Very simple! !

Port scan and listen

发送端：发送端每收到一个上层报文都会为其设一个唯一的序列号。收到的大报文进行分段，构造S/R报头，如 REF _Ref371456073 h 图表1所示。构造报头和数据部分连接后，按序从片段号=1的报文开始发送，并设置重传定时器，直到发送完毕。重传定时器截止之前，如果收到了接收端发送的完全确认，即数据分段全部被接收，则清除该该序列号报文的缓存和定时器；如果收到了部分确认则根据部分确认的指示重传丢失的分段；如果定时器截止时还没有收到任何接收端的回

做多客户端与服务器端的双向通信，采用QLocalSocket/QLocalServer实现起来简单，但通信效率太低，客户端发数据，服务器端的readyRead信号延时约100ms（看QT源码，发现里面用的是100ms定时器来检测信号），后来自己照着QLocalSocket的思路封装了windows的命名管道，采用多线程来接收数据，在本机上测试通过，通信效率有明显改善。-To do more client and server-side two-way communication, using QLocalSocket/QLocalServer to achieve them simple, but the communication efficiency is too low, the client made the data, the server-side readyRead the signal delay of about 100ms (see QT source code found inside using a 100ms timer device to detect the signal), and later their shining QLocalSocket encapsulates the idea of windows named pipes, using multiple threads to receive data, tested on this machine, the communication efficiency has clearly improved.

发送接收使用 winsock 文件我们不认为学习停止时提交的分配。这意味着作为智力努力找到分配"完美"的解决方案。我们是学生爱写漂亮的代码和重构的智力挑战的人。分配解决方案只被推到 Github 后他们提交截止时间。总是接受的请求。如果它 wasn 不明显，这不是正式的工作，从任何一所大学。想要这个运动的一部分吗？
