A Research Of Commands' Editing And Reproducing Mechanism Based On Analyzing Win32 Kernel Encoding And Decoding Mechanism

Along with the development of the information technology ,especially the computer network technology developed soon, its new application in modern education events became more and more widely and deeply, so the long-distance education expands quickly because of its native advantage. Depends on the network environment of our country nowadays, we need to realize the interactive and online study mode, but also decrease the network data-stream and the requirement of the bandwidth at the same time. So we bring forward a new method which is considered as a long-distance teaching mode based"command flow". It takes the education platform as the carrier, realize the interactive teaching stuff during the main class and the depart-class which relied on the commands'transmission through the internet. Compared with the large video frequency, commands flow is much smaller, and the requirements to the foundation instruments is exiguity, which would be suitable to widely use."The research of a mechanism named command's explaining system which is based on analyzing Win32 mechanism"is just come from the task"the long-distance education platform which is based on the commands flow", it's one of the most important part of the whole task, just wants to build a message-command mapping mechanism to transfer the commands in real-time, then make the events recur.In this article, we conclude the long-distance education patterns nowadays in board and aboard, then deeply expatiate the task's true meaning and its value. Divide the whole task after analyzing the demo's disadvantages and bring out a solution—the mechanism which is based on the MFC message-loop and Win32 multithreads application .After that, I give a completely explanation of the whole framework:1,Macrocosm framework introduces; 2,How to capture the commands and the research environment.;3,Analyzing the message-loop mapping then to make a new table;4,design the message capture mechanism combine the Win32 multithreads application, at last give an example and its code explanation.
