Hi all,

I need to know all file which is opened by application on my system. E.x if notepad open C:\abc.txt then I should receive "C:\abc.txt" when querying. I need that because I want all files that are located on the file server must be close when user sleep the computer.

I think I can hook the Windows message that open the file. But it is not perfect because I can just catch the file which is open after my application runs. Even if I want to do it, then I still do not know what exactly the Windows message I should handle.

Do you know any solutions for this? Thanks a lot.

You should watch a directory instead of a file to detect this. Here's an example:

Solution 1

You could use the FileSystemWatcher object.

Here's a CodeProject example:

Good luck!

Solution 2

I cannot use FileSystemWatcher because it can just catch Changed, Created, Deleted and Renamed events. If it can catch Open, Close events then it's ok.
Thanks for your reply.
