【转】毕业设计上线啦！----跳蚤部落与基于Comet的WebIM系统开发
【http://www.cnblogs.com/chenshengtai/archive/2011/12/10/2283267.html】
我不清楚把我的毕业设计的东西放上来之后，毕业论文答辩的时候会不会说我是在网上抄袭的，不过我还是果断的发上来与大家分享了！！呵呵，请大家支持！高手就绕道吧！
现在已经放到公网上，并且开始使用，兼容IE6以上各IE浏览器，Chrome，Firefox等。欢迎大家注册账号测试，注意如有使用特殊字符进行测试的，请测试完以后即使删除相关内容，以免给网站带来不美观的影响。谢谢！

其中涉及到的有：Server-Push（Comet），smtp，jQuery，jQueryUI，XHTML+CSS，Json，Jcrop，图形图像处理技术，Ajax，ADO.NET，kindeditor
开发工具包括：Visual Studio 2010、SqlServer 208、Notepad++、Editplus、SVN版本控制、Chrome、Firefox、IEtest、flashFXP、IIS6.0、IIS7.5
整个项目的流程图如下：
在这里与大家分享几个部分源代码：自己封装的类库与jQuery方法：
