Hello everyone, While exploring different ways to create a lightweight and flexible notification system, I realized that the IUserNotification interface is one of the least resource-hungry, especially if you're looking to implement a discreet and low-impact reminder system. I'm sharing here a small demonstration of this approach. The code below displays a customizable system notification with a title, message, icon, and optional system sound. It’s flexible and dynamic, and can easily be adapted for uses like reminders, subtle alerts, and more. 🔧 It uses: the COM object IUserNotification system icons extracted from shell32.dll a custom interface via AutoItObject 📌 This is just another way to do it — not necessarily better, but a useful option if you want to avoid heavy UDFs or external libraries for a simple need. #AutoIt3Wrapper_AU3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 #include "AutoItObject.au3" #include <WinAPIIcons.au3> #include <WinAPIShellEx.au3> ; Initialization _AutoItObject_Startup() #cs ; Constants for SetBalloonInfo Global Const $NIIF_NONE = 0x00000000 Global Const $NIIF_INFO = 0x00000001 Global Const $NIIF_WARNING = 0x00000002 Global Const $NIIF_ERROR = 0x00000003 Global Const $NIIF_USER = 0x00000004 Global Const $NIIF_NOSOUND = 0x00000010 Global Const $NIIF_RESPECT_QUIET_TIME = 0x00000080 #ce ; COM structure and interfaces Global Const $tagIUserNotification = _ "QueryInterface long(ptr;ptr*);" & _ "AddRef ulong();" & _ "Release ulong();" & _ "SetBalloonInfo long(wstr;wstr;dword);" & _ "SetBalloonRetry long(dword;dword;uint);" & _ "SetIconInfo long(ptr;wstr);" & _ "Show long(ptr;dword);" & _ "PlaySound long(wstr);" ; Function to create and display the notification Func CreateSystemNotification($sTitle, $sMessage, $iTimeout = 2000, $iIconIndex = Default, $sSound = "") Local $hIcon = 0, $pUserNotif = 0, $oNotif = 0 ; Create COM instance Local $CLSID_IUserNotification = _AutoItObject_CLSIDFromString("{0010890E-8789-413C-ADBC-48F5B511B3AF}") Local $IID_IUserNotification = _AutoItObject_CLSIDFromString("{BA9711BA-5893-4787-A7E1-41277151550B}") _AutoItObject_CoCreateInstance(DllStructGetPtr($CLSID_IUserNotification), 0, 1, DllStructGetPtr($IID_IUserNotification), $pUserNotif) If Not $pUserNotif Then ConsoleWrite("Error: Failed to create COM instance." & @CRLF) Return False EndIf ; Create wrapper object $oNotif = _AutoItObject_WrapperCreate($pUserNotif, $tagIUserNotification) If Not IsObj($oNotif) Then ConsoleWrite("Error: Failed to create wrapper object." & @CRLF) Return False EndIf ; Load icon Local $dwFlags = $NIIF_USER Local $iTotal = _WinAPI_ExtractIconEx(@SystemDir & '\shell32.dll', -1, 0, 0, 0) If $iIconIndex = Default Or Not IsInt($iIconIndex) Or $iIconIndex < 0 Or $iIconIndex >= $iTotal Then $iIconIndex = 13 ; Default icon ;ConsoleWrite("Warning: Invalid icon index.

So AutoIt does not have a good (fast) solution for things like: taking part of an array as a new array adding element(s) at the start or middle of the array In general array manipulation requires a loop, not a fast solution in AutoIt. I'm thinking using IDispatch to handle variable transfer between normal variables and the raw variant pointers. And fasm to do the array manipulation, importing the OleAut32 functions for variant manipulation. I expect this solution to be fast, and only require AutoIt and a fasm DLL, to work. My biggest issue currently is my lack of experience with ASM. I could try to throw something together, but would prefer help from someone, who actually knows what they are doing Any feedback on this idea is appreciated

This is more complicated than I thought. I have not found a way to read the path of the mounted ISO file via the WinAPI - only PowerShell: Get-Volume -DriveLetter Z | ForEach-Object { Get-DiskImage -DevicePath ($_.Path -replace '\\$','') } | Select-Object -ExpandProperty ImagePath Maybe WMI is also possible. Example: ;Coded by UEZ Global $sPath2ISO = "<path to your iso file>" MsgBox(0, "Test", $sPath2ISO & " already mounted: " & _IsISOFileMounted($sPath2ISO)) Func RunStdoutPS($sDrv) Local $sCmd = "powershell -NoProfile -Command Get-Volume -DriveLetter " & $sDrv & " | ForEach-Object { Get-DiskImage -DevicePath ($_.Path -replace '\\$','') } | Select-Object -ExpandProperty ImagePath" Local $tPipe = ObjCreate("WScript.Shell").Exec($sCmd) Local $sOutput = "" While Not $tPipe.StdOut.AtEndOfStream $sOutput &= $tPipe.StdOut.ReadLine() Sleep(10) WEnd Return $sOutput EndFunc Func _IsISOFileMounted($sISOPath) Local $aDrives = DriveGetDrive("CDROM"), $sVolumePath, $sDrive, $sResult If @error Then Return False For $i = 1 To $aDrives[0] $sDrive = $aDrives[$i] & "\" $sResult = RunStdoutPS($sDrive) If StringInStr($sResult, $sISOPath) = 1 Then Return 1 Next Return 0 EndFunc

FYI I was getting the same as FaustF with ?? in some of my output, I needed to modify the FileOpen to be 16 (Binary) #include <String.au3> $aFile=FileOpen(@DesktopDir&"\test",16) if @error then MsgBox(0,'ERROR',@error) local $firstLine=filereadline($aFile) $hexData=_HexToString ( $firstLine ) ConsoleWrite(@crlf&$hexData) Then I always get my expected value (0x%PDF-1.4 in my case) Just in case this helps anyone in the future !

I need from from time to time to run small processes to perform task that would otherwise clog the main process. Yes, there is a number of other UDF that could have done it very well, but I felt they were an over-kill for what I wanted. Don't throw me stones, I know it's not really multi-threading, but it is as close as I could get with simple AutoIt. If someone wonders why I called it PMT, the P stands for Pretending. And I'm also not pretending it is an elaborate UDF. Just small and simple to use... Version 2025-06-11 * increased the number of parameters up to 12 Version 2025-01-03 * changed how temporary files are deleted * changed location of temporary files to use standard folder * added support to unusual location of AutoIt Version 2025-01-02 * corrected bug when temporary files has space within their name. Version 2024-03-24 * corrected bug when 8 parameters (max) is passed to the function Example : #AutoIt3Wrapper_Res_SaveSource=y #include "PMT-UDF.AU3" #include <Constants.au3> _PMT_Init() Local $hProc1 = _PMT_Start("Test1", Default, "Test 1") _PMT_Start("Test2") _PMT_Start("Test3", 5) Local $sResponse While Sleep(50) $sResponse = _PMT_GetResponse($hProc1) If @error Then Exit MsgBox($MB_OK, "Error", "Process has dropped") If $sResponse <> "" Then MsgBox($MB_OK, "Success", $sResponse & @CRLF) ExitLoop EndIf WEnd Func Test1($sTitle, $sMessage) Local $iResp = MsgBox($MB_OK, $sTitle, $sMessage) Return "Done with value " & $iResp EndFunc Func Test2() MsgBox($MB_OK, "2", "Test 2") EndFunc Func Test3($iTimeout) MsgBox($MB_OK, "3", "Test 3", $iTimeout) EndFunc You can pass up to 8 parameters to _PMT_Start. It is up to you to manage the right number. You cannot pass structures, maps or arrays as parameter (only bool, ptr, hWnd, int, float, string, and the keyword Default). You could use my WCD-IPC if need be to exchange large amount of data. If you want to run it compiled, you need to have add #AutoIt3Wrapper_Res_SaveSource=y at the start of your script. In the case you decide to compile your script, _PMT_Init allows you to identity where AutoIt3 is located (in the situation where AutoIt is not installed in the usual directory) to get the right includes in your "threads". Let me know if you have any question, or suggestion, I will be glad to hear them. Enjoy. PMT-UDF.zip
