鼠标的形状看腻了吗，用这个程序改变一下吧，学习学习人家是怎么做的。-mouse in the shape of tired of looking at it, using this procedure to change it, learn from others is how to do.

不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

RSA算法伪代码，可能还不够成型，仅供大家学习参考用-RSA algorithm pseudo-code, might not be enough shape for them to learn from reference

VC++异形窗口，示范了如何使用VC创建以图片为对话框形状的异形窗口，本款异形窗口在WM_ERASEBKGND消息中自贴图，实现的方法和原理：先创建一个无背影画刷窗口，然后在WM_CREATE中并指定透明颜色, 缩放位图后加载至s_hdcMem中，最后在WM_ERASEBKGND中用s_hdcMem贴图即可。 　　实现时需要缩放位图、得到窗口大孝创建与窗口大小相等且能容纳位图的HDC - s_hdcMem、将原位图缩放到窗口大校 　　按下Esc键时退出（关闭）窗口。-Profiled
