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)' i( d' m( H3 h% r& _; E+ g
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。+ m6 m) P# `* {. A5 R( c! N8 z- f
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。7 ^5 ?+ K; i7 `2 N; P9 q, F; S
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8 }9 z+ X" G& w) l
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。
