本程序是单文档界面分割窗体的一种通信方法，自己感觉是比较笨的一种方法，可能使用消息映射的方法更好．







另外，开发周期也是一个不得不考虑的问题。程序工作在内核，稳定性/兼容性都需要大量测试，而且可供使用的函数库相对于应用层来说相当少。在应用层开发，调试修改相对要容易地多。



应用层截包驱动程序工作在操作系统内核，截断了所有的报文收发过程，并且把报文送到应用程序中处理，根据应用的策略，或者继续收发过程，或者丢弃，或者做其他的改变。



这个工具包提供了应用编程接口，允许应用程序处理报文，从而可以在实现以往必须写驱动程序才能做到的事情。



不考虑性能因素的话，在UCapture的基础上，可以实现所有的网络应用。



本文中的代码即实现了一个简单的防火墙。

-this procedure is a single document interface window in a separate communication methods, their feeling is a stupid comparison, the possible use of the method of mapping information better. In addition, the development cycle is one to consider. The core work procedures, stability/compatibility requires extensive testing, but the availability of libraries in relation to the application layer is concerned is very small. The application-layer development and debugging easier to change relative to the number. Application Layer Packet Driver cut in the operating system kernel, cut off all of the reported text transceiver process. and the text was put to the application process, according to the application of the strategy, or to continue the process of transceivers, or discarded. or do other
