LockFile allows you to lock a file to the current process. This is useful if you want to interact with a specific file but wish to avoid the accidental deletion by another process or worse still a user.

Examples have been provided and any advice for improvements is much appreciated.

            FileDelete($sFilePath) & ' (this will return 1, as the file is''t locked by AutoIt due to safety measures in place).')

    ; Unlock the locked file (though not really locked)
    FileClose($hLock)
EndFunc   ;==>Example_2

; Convert a boolean datatype to an integer representation

If you leave enough time for the caretaker to consolidate all files (without interference), I see no reason why not.

Thanks to everyone who voted, liked and posted a message of thanks here.

I only created it for the forum and not for my personal use as I see the question asked quite a bit around here, but perhaps I will find use for it as well.

I've updated the UDF with fixes to the return values of LockErase & included a new function called LockReduce. Download available in the initial post.

I might add something similar in the future but for now for those who use WinAPIEx.au3 by Yashied check out the following functions to accompany this UDF. Just pass the handle returned by LockFile() to the functions.

_WinAPI_FileInUse

_WinAPI_GetFinalPathNameByHandle

A sample script. Its a culmination of LockFile, WinAPIEx. A lot more things can be done. Basically, wrote this code to test "Unlocker Assistant", which can unlock any locked file.

Why this? well for a small project.

[seems like some issue with fileinuse... testing]

Well I had to download the WinAPIEx by Yashied and reinstalled it (used the installer). now the below script is working fine. and am using the latest version of Autoit v3.3.8.1.

#include "access.au3"
#include "array.au3"
#include "date.au3"
#include "LockFile.au3"
#include <WinAPIEx.au3> ; had to download the latest WinAPIEx.au3
AdlibRegister('CheckLock', 200)

Global $oMyError = ObjEvent("AutoIt.Error", "MyErrFunc")
Global $lockStat = 0
Global $sFilePath = @ScriptDir & 'test.mdb'

LockUnlock($hLock)
$lockStat = 0
Sleep(2000)
$val = _accessAddRecord($sFilePath, '', 'tran', '|test|10|0|0|' & _Now() & '|0|0', 2)

Hi Guinness,

I modified the script (which is now posted in the previous post) and also had to download the latest version of WinAPIEx .

The output of the running script:

Secondly, you will have to create a test.mdb and then execute the addrecord function. I am using a modified version of addrecord (which uses password as one of the parameter) I think in the original UDF password option is not available.

Last but not the least - for a faction of a second the DB is unlocked but you can open the DB in exclusive mode so that it is again inaccessible.

I don't use Access but I'm glad you're using my UDF to your advantage. Any ideas for new functions let me know and I'll see what I can come up with.

good script

can you create gui that contain folder open dialog and sub folders or files

after that choise some folder to lock it and another bottun to unlock it

This is going beyond the idea of the UDF, but there is nothing stopping you from creating it.

Updated the UDF will only a few cosmetic changes. I also won't be adding _WinAPI_FileInUse or _WinAPI_GetFinalPathNameByHandle, since the latest AutoIt beta/alpha versions contain WinAPIEx.au3, so seems silly to duplicate code that already exists.

To make it clear, this UDF is for those who want to 'lock' a file to the current process. If you have no idea as to why you would be required to do that, then you don't need this UDF.

Not to my knowledge. You would need to do a bit more work to the UDF to 'unlock' a file by another process, like Unlocker.

Search the Forum as some users have tried to create an Unlocker like application.
