主要修改了以下地方： 1、整理了后台，增加了系统设置功能，现在不用改网站页面就可以使用了此程序了 2、友情链接后台管理功能。考虑到大家很懒，就加上后台管理链接功能 3、对相册上传安全增加了点安全措施，只允许上传jpg,gif文件 4、修改了大量原1.0程序中的错误，现在没有内容时也不会出现错误 5、修改了金钱交易地方的漏洞-main changes the following places : one, compiled background, the increase in system setup functions now without changes to pages on the site can use this procedure the two, Links background management functions. Taking into consideration your pretty lazy, with background on the management functions of the three links, upload photos to a point increase security measures, allowing only upload jpg, gif four documents, a large number of amendments to the original 1.0 procedural errors were made, there is no content there will be no mistakes 5, revised the payment money transactions where the loopholes

采用CAsyncsocket类连接代理服务器-used CAsyncsocket category, Proxy Server

IOCP完成端口编程，源码可以直接使用，学习完成端口的好的素材-IOCP completion port programming, source code can be directly used to complete the port of a good learning material

可用来在计算机与计算机之间传输文件，还可用来在智能手机之间通过蓝牙、无线网络、数据线传输文件，支持多线程和断点续传，代码已经封装成一个dll库，可以作为服务器来使用，也可以当作客户端来使用，服务端支持蓝牙(Bluetooth)接入，并提供详细的测试程序，代码勿须任何修改用VS2005或VS2008编译一下即可拿到Windows Mobile中手机中使用。 你可以任意修改复制本代码，但请保留这段文字不要修改。 希望我能为中国的软件行业尽一份薄力！-Can be used in the computer and transfer files between computers, can also be used in smart phones through Bluetooth, wireless networks, data lines to transfer files to support multi-threading and HTTP, the code has been packaged into a dll library, you can as a server to use, also can be used as a client to use, service-side support for Bluetooth (Bluetooth) access, and provide detailed test procedures, code Needless to any changes to compile with VS2005 or VS2008 you can get in Windows Mobile phones use. You can modify a copy of arbitrary code, but please keep this text do not modify. Hopefully, I can for China s software industry fulfill thin edge!

一个关于串口通信编程的小程序，使用visual c++编写。-Serial communication programming on small procedures, the use of visual c++ Prepared.

信使小精灵,是一个简易的聊天工具。主要是演示了网络编程的主要步骤。本程序使用封装好的函数库，使得应用层不需要考虑网络消息是如何被接受和发送的，也不需要考虑数据粘包和丢包的刺手问题，你只要调用相应的函数就可以了。函数库为你做好了这些工作。你只需要定义自己的协议头和消息结构体，定义好网络消息的回调函数就可以了。-Messenger elf is a simple chat tool. Mainly to demonstrate the major steps in network programming. This procedure using the package a good library, making the application layer does not need to consider how the network news is accepted and sent, nor need to consider the data packet and packet loss sticky hands of the Spurs, you simply call the corresponding function can be a . Function library for you to do a good job in those efforts. You only need to define your own protocol header and message structure, the definition of good network news can be a callback function.
