LockFile() - Lock a file to the current process only.
krasnoshtan and one other reacted to guinness for a topic
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.

How to compress data in memory? The simplest way is to use the Native API Compression by trancexx. Here provides another way, using LZMA algorithm. LZMA is the default method of 7z format, provides a high compression ratio and very fast decompression. In this UDF, embedded and external DLL are both supported. If "LZMA.DLL.AU3" (embedded binary) is not included in scripts, a external LZMA.DLL must exists. You can use external DLL if MemoryDll is not work for you. Some tips: Both LzmaEnc and LzmaDec only accept binary arguments. To compress string, StringToBinary and BinaryToString can help.LzmaEnc can accept an extra argument, the comression level, from 1 to 9. For example: LzmaEnc($Binary, 9)More settings are support by LzmaEncSetting, please see LZMA SDK.This UDF is not for file compression. To compress files, 7-ZIP UDF is the better choiceExample: #include "LZMA.AU3" #include "LZMA.DLL.AU3" Local $Source = Binary("LZMALZMALZMALZMALZMALZMALZMALZMALZMALZMA") Local $Compressed = LzmaEnc($Source) Local $Decompressed = LzmaDec($Compressed) LZMA.zip1 point

Also, if you've installed the full install of Scite4AutoIt3 there's a macro recorder in the Tools menu, if you have a file with the .au3 extension open.1 point

welcome yes, absolutely AutoIt can do that. Au3Record.exe is included with AutoIt in the 'Extras' directory. if that's not to your liking, you can always write your own1 point

PlayHD, As AutoIt cannot read your mind, you will have to tell it when you want to move the button and when you want to click it - like this: #include <GuiConstantsEx.au3> #include <WindowsConstants.au3> #include <MenuConstants.au3> $hGUI = GUICreate("Test", 500, 500) $cCheck = GUICtrlCreateCheckbox(" Move", 10, 10, 200, 20) GUICtrlCreateLabel("Move me", 100, 50, 60, 20) GUICtrlSetBkColor(-1, 0x00FF00) $cButton = GUICtrlCreateButton("Me too", 40, 100, 80, 23) GUISetState() While 1 $msg = GUIGetMsg() Switch $msg Case $GUI_EVENT_CLOSE Exit Case $GUI_EVENT_PRIMARYDOWN ; Are we moving? If GUICtrlRead($cCheck) = 1 Then $cInfo = GUIGetCursorInfo($hGUI) $iControl = $cInfo[4] If $iControl Then $aPos = ControlGetPos($hGUI, "", $iControl) $iSubtractX = $cInfo[0] - $aPos[0] $iSubtractY = $cInfo[1] - $aPos[1] Do $cInfo = GUIGetCursorInfo($hGUI) ControlMove($hGUI, "", $iControl, $cInfo[0] - $iSubtractX, $cInfo[1] - $iSubtractY) Until Not $cInfo[2] EndIf ; Empty event queue to prevent the button firing Do Until GUIGetMsg() = 0 EndIf Case $cButton MsgBox(0, "Hi", "Button pressed") EndSwitch WEnd Any use?

if win do allow you to send data when he dont have focus that its possible, some wins will not work others will alow you to do that so use WinGetHandle instead WinActivate and use ID of the controll your sending the command, in your case thats Edit1 so dont remove it unless you need to send data to some other controll1 point -
If I have a fixed array I've recently started to use this approach with using Enum, thus eliminating the need for using 'magic numbers.' Local Enum $sLabelName, $hGUI, $iLabelID, $iGUIMax ; Use Enum to create variables from 0 to total number of variables. Local $aGUI[$iGUIMax] ; $iGUIMax is equal to the value of 3. $aGUI[$sLabelName] = 'This is a label.' $aGUI[$hGUI] = GUICreate(... $aGUI[$iLabelID] = GUICtrlCreateLabel(...1 point

Guess i gotta work some more on my english, sometimes i wanna write something and it turn out like something else that even i don't understand when i re read it tomorrow $handle = "0x00020616" is text so if your win title isnt 0x00020616 you do need to use something that will return handle like WinGetHandle('[CLASS:Notepad]') or some other command from help file so this shud work $handle = WinActivate('[Class:Notepad]') If $handle Then for $i =1 to 100 ControlSend($handle, "", "", "dummy text") Next EndIf When you store some handle to some file i do think that you will need to get all win handless compare thenm to handle that you need and use real handle instead text on that win. from help file It is important to note that a window handle is [b]not[/b] classed as a number or string - it is its own special type.
