About file ...

5 posts in this topic

Hi all, i have doubts about some file matter needing your help.

Normally, when a file is opened and using by a window or a program, it will be locked and associated with that program, with window restricting, so u can not delete, rename or save editting this file. I wonder that can we unlock or close a file which is using or opening by a program for deleting, renaming ... the file? Thanks.

Why do you want to delete/rename a file that another program has open? I'm sure that's going to cause some issues with that program when it tries to read/write to the file that's not there anymore.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Some program will automatic create a new file if the file is deleted or missing, or for example i need adjust some configuration conditions without exit the program, of course, i know when or how edit the file to not effect the program running. I just wonder if we can do it?

When it's your own program its possible if you don't lock the file, small example:

#cs -----------------------------------------------------------------------------------------------------------

    AutoIt Version: 3.3.6.1
    Author:                        AutoBert:    http://autoit.de/index.php?page=Thread&postID=164341#post164341

    Skriptbeispiel für den Umgang mit INI-Files und ComboBox
#ce -----------------------------------------------------------------------------------------------------------

#include <GUIConstantsEx.au3>
#Include <GuiComboBox.au3>
#include <StaticConstants.au3>

Const $sElect = "bitte eine URL auswählen"
Const $sAppIni=@AppDataDir&"\URLs.INI"
Global $URL

If Not FileExists($sAppIni) Then
    $sData = "AutoIt=http://autoit.de" & @LF
    $sData &= "Buch=http://autoit.de/index.php?page=Thread&postID=92818#post92818" & @LF
    $sData &= "richtig Posten=http://autoit.de/index.php?page=Thread&threadID=4424" & @LF

    $sData &= "MiniUrl-Manger=http://autoit.de/index.php?page=Thread&postID=164341#post164341" & @LF
    IniWriteSection($sAppIni, "URLs", $sData)
EndIf

$hGui = GUICreate("MiniUrl-Manager", 300, 90, 302, 218)
$hcboProg = GUICtrlCreateCombo("", 8, 8, 200, 25)
$hbtnAdd = GUICtrlCreateButton("&Hinzufügen", 213, 8,80)
$hbtnDel = GUICtrlCreateButton("&Löschen", 213, 35,80)
$hlblURL = GUICtrlCreateLabel("", 8, 70, 290,25)
$hbtnOpen = GUICtrlCreateButton("&Öffnen", 8, 35,200)
GUICtrlSetState($hbtnOpen, $GUI_DISABLE)
GUICtrlCreateGraphic(0,65,300,2,$SS_ETCHEDHORZ )
read_INI()
GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hbtnAdd
            $write1 = InputBox("URL", "Bitte eine gültige URL eingeben")
            If $write1 <> "" Then
                $write2 = InputBox("URL verwalten  unter", "Bitte Kurzbegriff eingeben")
                If $write2 <> "" Then IniWrite($sAppIni, "URLs", $write2, $write1)
                GUICtrlSetData($hcboProg, $write2, $write2)
            EndIf
            show_Selection()
        Case $hbtnDel
            $sDel = GUICtrlRead($hcboProg)
            IniDelete($sAppIni, "URLs", $sDel)
            GUICtrlSetData($hcboProg,"")
            read_INI()
        Case $hcboProg
            show_Selection()
        Case $hbtnOpen
            ShellExecute($URL)
            ;ConsoleWrite($URL & @CRLF)
    EndSwitch
WEnd

Func read_INI()
    $list1 = IniReadSection($sAppIni, "URLs")
    ConsoleWrite($list1 & @CRLF)
    if IsArray($list1) Then
        For $i = 1 To $list1[0][0]
            GUICtrlSetData($hcboProg, $list1[$i][0])
        Next
    EndIf
    _GUICtrlComboBox_InsertString ($hcboProg,$sElect,0)
    _GUICtrlComboBox_SetCurSel($hcboProg,0)
EndFunc   ;==>read_INI

Func show_Selection()
    If GUICtrlRead($hcboProg) = $sElect Then
        GUICtrlSetState($hbtnOpen, $GUI_DISABLE)
        GUICtrlSetData($hlblURL, "")
    Else
        GUICtrlSetState($hbtnOpen, $GUI_ENABLE)
        $Prog = GUICtrlRead($hcboProg)
        ConsoleWrite("ausgewählt: " & $Prog & @CRLF)
        $URL = IniRead($sAppIni, "URLs", $Prog, "")
        GUICtrlSetData($hlblURL, $URL)
    EndIf
EndFunc   ;==>show_Selection

in this example you can also change url's with editor while running and it takes effect. For programs which lock you can unlock with winapi-funcs, there are several example script in forum like:

 just search and test if they are runable with actual stable.
