请问各位高手，如果不用timer，怎么对某一个目录进行监控？

[ketao_78]

对某个目录监控的意思是说，发现该目录下有文件产生，就把它复制到另外一个目录下，同时产生一个ini文件。
现在关键是如何发现该目录下有文件产生，如何监控，轮循

[ketao_78]

to AechoJohn(江江)
这个方法不错，我再研究研究

[ketao_78]

timer是简单，但是必须不断的轮循，可能会影响效率，而且没有文件产生的时候也会不断的产生动作，而用api捕获消息的话，我觉得就不会这样了，

欢迎各位高手不断的提出意见~！

[思考]

我有,只要文件夹内文件有变化（包括文件日期、文件名、文件多少），就能立刻知道。

[思考]

不用timer控件，用api了

[ketao_78]

to bdxzq(思考) :
您好，能给出具体代码吗？
如果不太方便，能给个思路吗？
我的电子邮箱是[e-mail]

[online]

利用Windows的未公开函数SHChangeNotifyRegister实现文件目录操作即时监视程序可以监视在Explore中的重命名、新建、删除文件或目录；改变文件关联；插入、取出CD和添加删除网络共享都可以被该程序记录下来

代码太多了有个例子

谢谢，我把邮箱告诉你把
能发几个代码实例给我看看么？
