这是我在平时的学习&实践中的总结，分享给大家，希望有些提示，很多细节的东西没有写出，只能大家自己去体会去尝试：

1. Content check and error handling: using web_reg_find() functions everywhere, and write some error handling code to make sure LR can handle the requests in a proper way, like using lr_exit() function and lr_error_message() to write error messages in the controller console, so that we can track the error in time
2. Dealing with special characters using C programming language: define dynamic array and using pointer to handle that, and remember to free the parameters at the end.
3. Write Dll to make scripts shorter: using some open source tool to make Dll file which includes some common functions, then we can call the common functions dynamically and make scripts shorter.currently I use Code::Blocks and MinGW compiler， i do not use VC++, because it is not free :)
4. Look at the detail log message on demand: using lr_set_debug_message() function, you can open and close it on demand, so make your debug skill more efficiency.

5. using Ajax(click& scripts) instead of web (click & scripts )and web(http&html), you can combine Ajax and Http method together when you are writing the scripts

6.Learn how to use regular expression, a very powerful and helpful "tool"!
