在NT系统里,一个进程只允许对本身内存和共享内存进行读写(如果说错了请告诉我), g! G, j! \0 T2 g$ p9 n9 z2 @
但经过处理后,我们可以访问安全级别不是很高的进程内存。$ D5 ?2 N6 G- z. Y
我们在OpenProcess时,如果能取得它的PROCESS_VM_READ、PROCESS_VM_WRITE和PROCESS_VM_OPERATION权限,那就好办了。6 p8 t% O( |! y! t
下面是我编的一个自动扫雷程序的核心代码,它从扫雷程序的内存中读取地雷的分布情况,再通过模拟鼠标点击来扫雷- L- E" P9 K/ w& k. p' G; a
注意,这儿地雷在内存中的分布,是在中文XP下跟踪所得,不知道在其它系统上是不是一样的。- R: x l& u/ k
