如何在BCB里面上传文件？ 用NMStrmStrv接受和NMStrm发送控件 (How to upload files inside the BCB? With NMStrmStrv receive and transmit control NMStrm)

实现了基本的网络的通讯，这是很基本的，也许有点简单，但希望多少能给你点帮助-The basic implementation of the communications network, which is very basic, perhaps a bit simple, but how can you hope to help the

1.   实现单线程文件传输功能； 2.      在以上基础上，掌握多线程技术，在文件网络传输时，可选择单线程或多线程； 3.       请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

说明：  stun协议，实现私网地址转换，也就是NAT转换(NAT map)

一个通过网络高速传输文件的控件： 具有以下特点 1.有高速数据传输功能，超过了Winsock控件的吞吐量 2.入校验功能，满足大数据包的收发，理论上不限数据尺寸 3.加入防错代码，提高了接口鲁棒性(through a network of high-speed transmission of documents, the controls : one with the following features. A high-speed data transmission functions Controls over the throughput of Winsock 2.- Check function and meet large data packet transceiver, Theoretically Open-data size 3. to prevent the wrong code, improve the robustness Interface)

一套完整的企业内部网站，有论坛、信息发布、信息反馈功能。稍加修改就可搭建自己企业的内部网。-a complete set of enterprise websites, forums, information dissemination, information feedback. Little changes can be their own corporate structures in the internal network.

使用定时器示例代码 Use the timer MFC sample code()

这是一个简单的socket编程例子，非常适合刚接触socket编程者。程序简单、可用、易于理解。是个很好的socket范例。(A simple socket programming examples. Suitable for beginners. Program is simple, available, easy to understand. Is a good example of socket programming.)

NAT(Network Address Translators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(Network Address/Port Translator)。(The principle and implementation of UDP NAT through P2P )

说明：  运用Dijkstra算法的航迹规划，可以避障，对学习很有用(Track planning using Dijkstra algorithm can avoid obstacles and is very useful for learning.)
