In recent projects, project source code confidentiality issues are involved, because the code is written in C #, easy to decompile, so the decision to extract the core algorithm part of the use of C + + writing, C + + so far seems to have not been very good decompile, of course, if you are a disassembly master, perhaps it is possible to decompile. This means that C # managed

The code block in 4 in Java is summarized as follows:* Add static code block, write a pair of {} in the class to construct a block of code, in the method write a pair of {} is a common code block,* There is also a code block in Java that is a synchronous

The previous blog briefly introduced the computer Central Plains code, back code, complement and shift code representation (http://blog.csdn.net/xdd19910505/article/details/40424533), for the computer why it is not very clear, it seems to know such a thing, but I don't know why. It's like a person you don't know, he's not his friend, you don't know what he's ....

First, Location codeIn order to adapt to the need of computer processing Chinese character information, China promulgated the GB2312 National Standard in 1981. The standard selects 6,763 commonly used Chinese characters (among them, the first class commonly used Chinese characters 3,755, two Chinese characters 3,008) and 682 non-Chinese characters, and has stipulated the standard code for each character, in order to carry on the Chinese text exchange
Values have positive and negative values, and the computer uses the highest bit of a number to store the symbols (0 is positive, 1 is negative ). this is the original code of the number of machines. assume that the number of digits processed by the machine is 8. that is, the word length is 1 byte, and the original code can indicate the value range is 127 ~ (-127)Source
See a lot of people need, put it out, good things to share with everyone.
Copy Code code as follows:

I wrote a PHP verification code class, and later debugging found that when the code generated by invoking the PHP file, the verification code on the image is always inconsistent with the actual verification code string, but when the file embedded in the HTML is not the problem, everything is normal, very strange.
