      Here another approach to check if a script was already started using atoms and semaphores.
      #include <MsgBoxConstants.au3> Global $iSingleton = Singleton() If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!") EndIf MsgBox($MB_TOPMOST, "Singleton Test", "Singleton atom initialized: " & $iSingleton) Singleton_Delete($iSingleton) ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton ; Description ...: Checks if the script has been started already. ; Syntax ........: Singleton([$sOccurrenceName = @ScriptFullPath]) ; Parameters ....: $sOccurrenceName - [optional] a string value. Default is @ScriptFullPath. ; Return values .: If the function succeeds, the return value is the newly created atom or 0 else error is set and false is returned. ; Author ........: UEZ ; Modified ......: ; Remarks .......: If Singleton finds the atom it will return 0 and the atom token will be set to extended macro.

      #include <MsgBoxConstants.au3> #include <WinAPIError.au3> Global $iSingleton = Singleton("&]8h/x87</htFV4-K*&.b.w~") If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!")

EndFunc ;==>Singleton  
      Just start the script twice to see if it works.
      The disadvantage of using atoms is that atoms have a memory that means when your app is crashing or you forgot to delete the atom then the atom does still have the $sOccurrenceName saved and thus Singleton will not work if you use the same same value for $sOccurrenceName.
      With semaphore you don't have this issue.

      So I am trying to click the green button, this button is not always in the same place. So fare I am trying to click it by finding the color but there is also something else with the same color on the screen (circled in yellow) that is causing issues. Is there a way to use the Title and Class of the window (can't be just the window as there are more than one with the same name).
      How does AutoIt Info get this information?

    • By BlueSkyMemory
      Hello guys! I'm a rookie in AutoIt lol.
      I've tried to looking up in MSDN and the UDFs, but it can only get the GUID of a usual partition and with the GUID to control it. Now I have no ways😥.
      Thanks a lot for your help!

      Hi guys
      AutoIt content - Microsoft thinks any AutoIt content is unwanted.
      What it does is simply delete any EXEs. No option of do you want to continue...
      The March 2020 updated has substantially changed the Defender Virus Protection logic and layout.
      I found three pages relevant to the help, and lots of outdated content. Is there a quick and easy way to set folder exclusions? Any help is appreciated and simply using google is not good enough, as this is a new problem, caused by the update.
      Any ideas please?
      Found it.
      Accessing the menu through the Control Panel does not work
      Click the Defender shield in the icon tray.
      Scroll down to Virus & threat protection settings click Manage Settings Scroll down to Exclusions click Add or remove exclusions then click the + for Add an exclusion, and select File / Folder / File type / Process 
      Select Folder and browse to select. 😥

      Hi all,
      I'm trying to automate the install of a specific networking device. All goes well, I can install the driver on both Windows 7 & 10, rescan for hardware, set the IP-settings and all, but there's one issue. In Windows 10, I can disable all connection protocols using Powershell, but Windows 7 does not offer this Powershell-Cmdlet. So I programmed a way (two years ago) to let AutoIt open the network-adapter properties and then deselect all checkboxes except for the TCP/IP-V4. I recovered this snippet somewhere in my old files and tried to reintegrate this into my latest script, but it doesn't seem to work. On Windows 10 I get a blank screen for a few seconds and that's it, on Windows 7 it makes explorer crash. 
      I think it's quite safe to test this on your own system as long as you're not using IPv6 to connect to the internet and as long as you return to check all the boxes again (so you don't break your connectivity).
      If  anyone has any idea, I'd be glad to hear from you!
      Thanks in advance and stay safe in these Corona-ridden times 🙂
      Kind regards,

      There are three functions involved:
      This one is the main function that 'should' uncheck all the checkboxes in the adapter's Properties-window.
      Func DisableAllProtocols($AdapterName) OpenNetConnToAdapter($AdapterName) ;Find the IDs of all relevant controls Local $Handle_Window_Properties = WinWaitActive($Adaptername & " Properties","") Local $Handle_Listview_Protocols = ControlGetHandle($Adaptername & " Properties","","[CLASSNN:SysListView321]") Local $Handle_OK_Button = ControlGetHandle($Adaptername & " Properties","","[CLASSNN:Button6]") Local $List_CMN_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Client for Microsoft Networks") Local $List_FPSMN_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","File and Printer Sharing for Microsoft Networks") Local $List_QOS_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","QoS Packet Scheduler") Local $List_MNAMP_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Microsoft Network Adapter Multiplexor Protocol") Local $List_MLLDPPD_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Microsoft LLDP Protocol Driver") Local $List_IPV6_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Internet Protocol Version 6 (TCP/IPv6)") Local $List_LLTDR_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Link-Layer Topology Discovery Responder") Local $List_LLTDMIOD_ID = ControlListView($Adaptername & " Properties","","[CLASSNN:SysListView321]","FindItem","Link-Layer Topology Discovery Mapper I/O Driver") ; Disable All Protocols Except IPV4 SetCheckboxState($Handle_Listview_Protocols,$List_CMN_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_FPSMN_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_QOS_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_MNAMP_ID,3) SetCheckBoxState($Handle_Listview_Protocols,$List_MLLDPPD_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_IPV6_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_LLTDR_ID,3) SetCheckboxState($Handle_Listview_Protocols,$List_LLTDMIOD_ID,3) ;Click OK ControlClick($Handle_Window_Properties,"","Button6") Sleep(50) WinClose("Network Connections") EndFunc OpenNetConnToAdapter($AdapterName)
      This function opens the network adapter's Properties-page
      Func OpenNetConnToAdapter($AdapterName) ShellExecute("control.exe","ncpa.cpl",@WindowsDir,"",@SW_SHOW) WinWait("Network Connections","") WinActivate("Network Connections","") Local $Handle_Window_NetworkConnections = WinWaitActive("Network Connections","") Send("{F5}") Sleep(250) Local $AdapterNameArray = StringSplit($AdapterName,"") For $i = 1 To $AdapterNameArray[0] Step 1 Send($AdapterNameArray[$i]) Sleep(10) Next Sleep(50) Send("{APPSKEY}") Sleep(50) Send("{R}") Sleep(500) Return EndFunc SetCheckboxState($Handle,$checkbox_id,$wantedstate)
      This function changes the state of a checkbox
      Func SetCheckboxState($handle,$checkbox_id,$wantedstate) ;$handle : SysListView32-handle ;$checkbox_id : The ID of the checkbox you want to control ;$wantedstate : The wanted status (2 for checked, 3 for unchecked) Local $currentstate = _GUICtrlListView_GetItemStateImage($handle,$checkbox_id) If $currentstate = $wantedstate Then Return Else _GUICtrlListView_SetItemSelected($handle,$checkbox_id,True,True) Send("{Space}") Sleep(50) Return EndIf EndFunc
