谢谢各位了，我很笨，又没有受过正规教育，汇编学不会，c++都学个半瓶子

想要生得快，又不占CPU，那建议你去整个汇编的。高级语言在执行一项操作时，往往会来来回回反复执行一些与你的目标没有直接关系的过程，使用汇编直接地生成字典会比高级语言快一大截。

CPU占用大的问题,那没办法,这个时候就是需要CPU大量运算的时候.

不过话说回来,内容只是数字,字母,则应该可以使用直接填充内存的方式提高效率....

因为它们的ASCII码都在255以内.

比如:

type mystr

    byteASC() as byte

end type



dim arrPWD(10000) as mystr

这样的话直接对这结构中的数值进行操作,完成后使用copymemory进行填充,应该会比直接字符串操作要好些吧.....
