Hello every body,

In an application written using VC++2005 with MFC support, is there a way to know if a file copy is in progress (some where else in windows, not especially in my application) ?

Thanks in advance,
Mike

Suggestion: Try to obtain an exclusive lock on the file, if you can't it's probably being modified.

It's not want I want. I don't know anything about the file.
I only want to know if a FileCopy is somewhere in progress what else which file is being copied.

Oh, ok. I might help to know why you want to do this -- what's the rational? There might be a different way to approach this.

If a file copy is in progress, I must disable some controls in my application.

At first thought you would need to hook the API functions CopyFile and CopyFileEx, as I would imagine most copying on the system would employ one of those API functions.  Wait for the function to exit, then you know the copy has been completed so you can enable your controls.

That said, I don't know much about it myself, although if you look hard enough I am sure there is some info out there about hooking API function calls.
