Visual C#实现按回车键让焦点在录入控件中移动的窗口,回车切换控件焦点//要想使这个方法起到作用先将窗体的keypreview属性改为true，此功能看上去要更加智能一些，对于经常使用键盘操作的录入员来说，是个很实用的功能，无需让用户去定焦确认，省去了一些录入的宝贵时间。 ，作者拥有版权，仅供学习与参考。(Visual C# and press the Enter key to move the focus in the input control in the window, enter the switching control focus// to make it play a role in the form s KeyPreview property to true, this function seems to be more intelligent, to often use the keyboard input member, is a very practical function, without allowing users to focus confirmation, saves the precious time.

从libnids得到TCP重组的数据，当libnids的状态为NIDS_JUST_EST时，表示TCP建立连接，在此时给TCP流增加一个flow_id用来标识此连接；当libnids的状态为NIDS_DATA时，表示接受数据，当有新的数据到达时，根据flow_id把数据push到相应的流表中，为之后的数据分析做准备。因此，可以在此框架上增加符合http协议的应用解析(Data TCP libnids restructuring, when libnids status to NIDS_JUST_EST, said the TCP connection is established, at the same time adds a flow_id to TCP flow is used to identify this connection When libnids status to NIDS_DATA, accepted data, when new data arrives, according to flow_id to push data to the corresponding flow table, prepare the way for after data analysis. Can be increased on this framework, therefore, in accordance with the application of the HTTP protocol parsing)
