一解码程序，挺好的东东，不过是用汇编写的，希望能对大家有所帮助。其中还有一个是hcs系列芯片的接收程序。-a decoding procedure very well, the Eastern, but is the compilation was made in the hope that it can be helpful to everyone. Among them were a series of chips is hcs reception procedures.

介绍利用AFEPack求解自适应有限元的基本使用方法. 其输入参数为利用easymesh对区域进行剖分后的得到的文件.-AFEPack introduce the use of adaptive finite element to solve the basic usage. Its input parameters for the use of easymesh region after the partition of documents.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used (In VB- The same technique can be implemented in

Base64编解码，纯c语言，解码忽略换行符，可以直接解码邮件源码

通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.
