Detecting File Accesses

Question:

In a program that I'm writing, I need to know when any file is opened or saved and what the name of that file is. Is there an easy way to make a hook procedure with the Windows API or messages?

Answer:

Yes, the Windows operating system does offer such a hook, at least in Windows NT 4.0 and in Windows 2000. The following should also work with Windows 98/ ME.

You could dig through the Windows API files, but luckily there is also an easier way to accomplish this task � use the excellent free component library RxLib. It contains a component that does exactly the desired function.The name of this component is TRxFolderMonitor.
I have used this TRxFolderMonitor component in one network application and it worked really great - no need to dig in the source.

You simply put a TRxFolderMonitor component on your form and assign the Directory property the directory which you need to monitor. You can even tell the component to monitor subdirectories (recursively)!

TRxFolderMonitor will create a thread for you that gets activated in the even of a detected change.
