Monitoring A File For Access?

[b8bboi]

Hi all,

I need to write a script that sits in the background and monitors a file. Anytime that file is accessed, the script will do something. Here's my attempt. Should be simple enough.

Opt("TrayAutoPause", 0)
AutoItSetOption ( "TrayIconHide", 0 )
$FileToMonitor = "test.txt"

$lastAccessTime = FileGetTime($FileToMonitor, 2, 1)
While 1=1
    $currentTime = FileGetTime($FileToMonitor, 2, 1)
    If $currentTime <> $lastAccessTime Then
        MsgBox(0, "", "File changed", 3)        
        $currentTime = FileGetTime($FileToMonitor, 2, 1)
        $lastAccessTime = $currentTime
    EndIf

    Sleep(100)
WEnd

The problem is Windows caches files for accessing. If you keep opening a file multiple times, it'll be cached into RAM and the Access Time won't change. Is there any way to prevent this?

Also, in C++, there's a function called FindFirstChangeNotification, which can give real-time info on a file, including access time. Is there an equivalence for AutoIt?

If there's another way to do this, please tell me.

Thanks.

per help

option [optional]Flag to indicate which timestamp

0 = Modified (default)

1 = Created

2 = Accessed

maybe try for the modified date???

If you know much about C++ you could write a plug-in dll to use the function you mentioned to monitor the file in real time with AutoIt.

I am sorry I dont have a more direct answer.

Thanks but I don't need the modified date. I need to monitor the accessed date.
