Automating tasks with AutoIt

Introduction

AutoIt is a freeware alternative to applications like AutoHotKey to automate tasks through hotkeys/hotstrings and drive GUI applications. It used to be open-source — AutoHotKey was forked from AutoIt around 2005 —, but was closed-source later after a family feud. AHK is updated more frequently than AutoIt.

AutoIt is a procedural language and its syntax looks like BASIC, while AHK is a mix between C and Pascal. Although it has nowhere near the breadth of eg. Python, AutoIt could be good enough and used as an alternative to (Power|Pure|Free)Basic to write CLI/GUI apps.

In addition to native features, AutoIt is enhanced through User Defined Functions (UDFs), which are themselves coded in AutoIt and thus also have the .au3 extension. Some of them are included in the AutoIt installer, while others must be downloaded and installed manually — preferably in the User Include Folder as set through Tools > SciTE Config/CTRL+1. As AutoIt ships with a modified version of SciTE, it's not a good idea to manually upgrade it. If you still want to run a more recent version, check the thread.

Since AutoIt is primarily meant to automate the use of GUI apps, one of the important UDFs is IUIAutomation, which is the AutoIt implementation of Microsoft's UI Automation; It provides more ways to interact with GUI widgets.

Learning AutoIt

In addition to the AutoIt.chm help file — which is the offline version of the online doco —, the wiki, the forum, and the source code examples in \AutoIt3\Examples, information can also be found in the following:

"Program on Windows Using FREE Tools with AutoIt" by Jayme "JFish" Fishman (2015)
"Learning to Script with AutoIt V3" by Alex "LxP" Peters, updated by Brett Francis (2010)
Andy Flesner's AutoIt v3: Your Quick Guide (2007)
Valuater's "Welcome to AutoIt 1-2-3" (2006)
Tutorials
Tutorial Core Language
Best coding practices
(videos) TutsTeach's AutoIt Tutorials, 403forbidden403's AutoIt Tutorials

There are no more recent books to learn (but then, AutoIt isn't updated very frequently), and the help file is mostly a reference manual not a tutorial, although each function does include one or more examples.

A possible plan to learn AutoIt:

Download and install the AutoIt full package, launch the SciTEAutoIt editor, and run "Hello, World!"
Core Language: Variables, conditional statements, loops, functions, string manipulation, arrays, files and directories
Hotkeys
Automating GUI apps
Automating CLI apps (RunWait(), Std*(), etc.)
UDFs
Writing GUI apps

Getting Started

As of version 3.3.6.1, AutoIt consists in the following programs:

The SciTE editor, either in Lite or Full version with AutoIt-specific extensions; Using SciTE provides auto-completion and an easy way to compile AutoIt scripts
AutoIt3.exe: To run an AutoIt script from outside the SciTE editor
Au3Info.exe: To retrieve information on a running application
Au3Record.exe: To record an action, and have AutoIt turn it into a script; Due to too many antivirus false positives, it's no longer included in the installer and must be downloaded separately
Au3Check.exe: Syntax checker
AutoItX3.dll: A COM interface so you can include AutoIt into an application
Aut2exe.exe: To turn an AutoIt script into a stand-alone, self-contained EXE
upx.exe: To compress an EXE
User-defined functions (UDF's; Standard files can be found in AutoIt's \Include\ sub-dir)

To install UDFs, if you're using SciTE4AutoIt3, it's better to create a new directory outside the AutoIt folder so that the files aren't affected when upgrading AutoIt. To tell SciTE to find those files, use Tools > SciTE Config, and fill the "User Include Folders" in the "General 1" tab.

Working with windows (automating)

AutoIt's original raison d'être.

To find information about a window

Use install\Au3Info.exe.

Check UIASpy - UI Automation Spy Tool

To find a window

There are two parts: Its Title, and "Text" which can be any text found in the window (buttons, textboxes, etc.)

WinWaitActive("Untitled - Notepad", "This is some text!")

Timeout can be increased thusly:

Opt("WinWaitDelay", 1)

To find a window with just part of title/text

Opt("WinTitleMatchMode", 1) ;1=start (default), 2=subStr, 3=exact, 4=advanced (deprecated), -1 to -4=Nocase

Note: Opt() = AutoItSetOption()

More information here.

WinExists, WinActive, WinWait, WinWaitActive, WinActivate, _WinWaitActivate?

Const $MyWindow="My window"

WinActivate ($MyWindow)

if WinWaitActive($MyWindow, "", 5) = False Then

MsgBox($MB_SYSTEMMODAL, "Failed finding window", "Bad")

Else

;Do something

EndIf

https://www.autoitscript.com/autoit3/docs/functions/WinExists.htm

https://www.autoitscript.com/autoit3/docs/functions/WinWait.htm

https://www.autoitscript.com/autoit3/docs/functions/WinActive.htm

https://www.autoitscript.com/autoit3/docs/functions/WinActivate.htm

https://www.autoitscript.com/autoit3/docs/functions/WinWaitActive.htm

_WinWaitActivate() is not a native function: It is generated by the Au3Record.exe application, which no longer ships with AutoIt "from v3.3.14.1 as it triggers many AV false positives".

Func _WinWaitActivate($title,$text,$timeout=0)

Local $result = False

$result = WinWait($title,$text,$timeout)

if $result = False Then Exit MsgBox($MB_ICONERROR,"Bad...","Window not displayed")

If Not WinActive($title,$text) Then WinActivate($title,$text)

WinWaitActive($title,$text,$timeout)

EndFunc

To record an action

Launch \Extras\Au3Record\Au3Record.exe to record an action that Au3Record will then save as source code that you can use in your scripts.

Caution: Code generated Au3Record isn't always reliable, some functions won't work. YMMV.

Note: _WinWaitActivate() is not part of AutoIt; Its code found below must be included in the script.

Note: "AutoIt Recorder utility is not available from AutoIt Version 3.3.14.1." (source)

To use control/arrow keys

;CTRL+A

Send("^a")

Sleep(3000)

;CTRL+C

Send("^c")

;CTRL+V

Send("^v")

;jump to first line in text

Send("^{HOME}")

Accessing a control/widget

ControlSend("Untitled - Notepad", "", "Edit1", "This is some text")

ControlClick("My Window", "", "[ID:254]")

To send keys to window/control

http://www.autoitscript.com/autoit3/docs/functions/ControlClick.htm

http://www.autoitscript.com/autoit3/docs/functions/ControlCommand.htm

http://www.autoitscript.com/autoit3/docs/functions/ControlSend.htm

http://www.autoitscript.com/autoit3/docs/functions/ControlFocus.htm

(only as last resort)

http://www.autoitscript.com/autoit3/docs/functions/Send.htm

http://www.autoitscript.com/autoit3/docs/appendix/SendKeys.htm

How to interact with controls

Besides the Control*() functions, there are also: StatusbarGetText, WinActivate, WinGetClassList, WinMenuSelectItem.

ControlSend("Untitled - Notepad", "", "[CLASSNN:Edit1]", "This is some text")

ControlSetText("My Window", "", "[NAME:textBoxFolder]", "C:\Some\Folder")

ControlClick("My Window", "", "[ID:254]")

ControlClick("My Window", "", "[CLASS:Button; TEXT:Finish; INSTANCE:2]")

Note: ControlSetText() sometimes doesn't work as expected; If that case, try ControlSend() instead.

Sample code

Hello, world!

#include <MsgBoxConstants.au3>

MsgBox($MB_OK, "Tutorial", "Hello World!")

The EXE is about 1MB, and its size can be halved further through UPX.

Prompting for a string

#include <StringConstants.au3>

Local $sAnswer = InputBox("Type anything", "My text")

if not $sAnswer Then Exit ConsoleWrite("Closed inputbox" & @CRLF)

$sAnswer = StringStripWS($sAnswer,$STR_STRIPLEADING + $STR_STRIPTRAILING + $STR_STRIPSPACES)

;Two items expected

If $aArray[0] <> 2 Then Exit ConsoleWrite("Expected two items, got " & UBound($aArray)& @CRLF)

Local $item1 = $aArray[1]

Local $item2 = $aArray[2]

Prompting for a directory

Local $sFileSelectFolder = FileSelectFolder("Select a folder", "")

If @error Then Exit ConsoleWrite("Closed directory dialog" & @CRLF)

Prompting for files

#include <File.au3>

$aArray = _FileListToArrayRec($sFileSelectFolder, "*.jpg", $FLTAR_FILES , $FLTAR_RECUR, $FLTAR_NOSORT,$FLTAR_FULLPATH )

If UBound($aArray) = 0 Then Exit ConsoleWrite("zero elements") ;1D array only

Showing the current line in the script

ConsoleWrite(@ScriptLineNumber & @CRLF)

Variables and constants

Variables are stored as variants, must start with the $ character and may only contain letters, numbers and the underscore _ character. Note that all variable names are case insensitive: MyVariable() is the same as MyvARiAblE(). Variables are declared and created with the Local and Global keywords - Dim can also be used, although this is not recommended. Although all variables outside functions are automatically Global, and all variables inside functions are Local, it's good practice to use the right keyword.

Constants are declared and created using Const keyword and must be initialised with a value.

To refer to macros such as environment variables: @ComputerName

Although not required, it's best practise to start a user defined function name with the underscore “_” to differentiate it from prebuilt functions, eg. _myFunction().

It's a good idea to use "Opt('MustDeclareVars', 1)" to make sure variables are always declared. Or even better: Use the following type of command to tell AutoItWrapper to call Au3Check.exe:

#AutoIt3Wrapper_AU3Check_Parameters=-d -w 3 -w 4 -w 5 -w 6

To edit a script

Launch the SciTE editor in install\SciTe\SciTE.exe

To clear the console window in SciTE, use SHIFT+F5. To check a script's syntax without running it, use CTRL+F5.

To comment a line

Use ";"

To comment a block of text

SciTE/AutoIt provides three options to comment a block of lines; Only the first option provides a way to uncomment

Block Comment or Uncomment (CTRL+Q): ;~
Box Comment: #CS ; #CE
Stream Comment: #CS #CE

In addition, AutoIt provides a fourth way to comment a block of text:

#comments-start

…

#comments-end

To read the command-line input parameters

MsgBox($MB_OK, "Passed Parameters", $CmdLine[0] & " parameters have been passed to this script:")

For $i = 1 To $CmdLine[0]

MsgBox($MB_OK, "Passed Parameters", "Parameter " & $i & ": " & $CmdLine[$i])

;Get input file

If $CmdLine[0] == 1 and $CmdLine[1] and FileExists($CmdLine[1]) Then

$INPUTFILE = $CmdLine[1]

EndIf

To prevent the user from disturbing the script

; Disable user input from the mouse and keyboard.

BlockInput($BI_DISABLE)

; Blah

BlockInput($BI_ENABLE)

To split a long string

"my " & _

"long string"

Trimming string left and right

#include <StringConstants.au3>

;to remove spaces within, add + $STR_STRIPSPACES

Local $sString = StringStripWS(" Blah ", $STR_STRIPLEADING + $STR_STRIPTRAILING)

MsgBox($MB_SYSTEMMODAL, "", $sString)

Array

The array.au3 UDF offers extended functions to handle arrays, eg. _ArrayDisplay($myarray)

Enum is a way to mimic dictionary arrays:

Local Enum $eTitle, $eIntroText_bb, $eFullText_bb, $eName

ConsoleWrite($aResult[$eTitle])

To set/get clipboard contents

#include <Constants.au3>

#include <MsgBoxConstants.au3>

#include <Date.au3>

#include <Clipboard.au3>

ClipPut(_NowTime())

Local $sClipboard = ClipGet()

MsgBox($MB_SYSTEMMODAL, "Clipboard", $sClipboard)

To send large amounts of text to a text widget

Pasting the clipboard with ClipPut() or send("^v") is much faster than sending text via send().

Since send() is a blocking function, it's not supposed to proceed until it's done sending the text anyway.

For/Next Loop

For $i = 5 To 1 Step -1

MsgBox($MB_SYSTEMMODAL, "", "Count down!" & @CRLF & $i)

To pause for a few seconds

Sleep(1000) ; sleep for 1s

To move the mouse at the center of the screen

#include <Misc.au3>

CHECK MouseMove(@DesktopWidth/2, @DesktopHeight/2)

Including files

To include files: #include <myfile.au3>

To include an external file into the AutoIt output EXE à la NSIS: FileInstall(Source,Destination[,flag])

Writing to a text file

#include <FileConstants.au3>

$sFileName = @ScriptDir &"\Test.txt"

$hFilehandle = FileOpen($sFileName, $FO_OVERWRITE)

If FileExists($sFileName) Then

MsgBox($MB_SYSTEMMODAL, "File", "Exists")

Else

MsgBox($MB_SYSTEMMODAL, "File", "Does not exist")

EndIf

FileWrite($hFilehandle, "This is line 1")

FileFlush($hFilehandle)

MsgBox($MB_SYSTEMMODAL, "File Content", FileRead($sFileName))

FileClose($hFilehandle)

;FileDelete($sFileName)

Exiting

Exit

Exit(1)

Exit(2)

If some_error Then Exit MsgBox($MB_SYSTEMMODAL, "You have an error", "Some text")

StringRegExp(Replace)

A first example:

#include <StringConstants.au3>

Local $aResult = StringRegExp("This is a test example", '(te)(st)', $STR_REGEXPARRAYMATCH)

If Not @error Then

MsgBox($MB_OK, "SRE Example 4 Result", $aResult[0] & "," & $aResult[1])

EndIf

There is apparently no way to configure PCRE externally for the duration of a script, ie. without adding settings to every single pattern.

Note: The PCRE regex engine that AutoIt uses is single-line by default. If you need to find a pattern in a multi-line string, you must tell PCRE explicitely: Prepend (?m) for multi-line:

$array = StringRegExp($data, "(?mi)^(\d+) some text", 3)

Here's how to extract the second part in a two-item string with a TAB delimiter:

$array = StringRegExp("John" & @TAB & "123", "\t(\d+)', 1)

for $i = 0 to UBound($array) - 1

msgbox(0, "Items found", $array[0])

To find and replace patterns:

Local $sOutput = StringRegExpReplace($sInput, '(\d{2})/(\d{2})/(\d{4})', ' $2.$1.$3 ')

The flag can have five different values:

$STR_REGEXPMATCH (0) returns 1 (true) or 0 (false) if the pattern was found or not. Default.
$STR_REGEXPARRAYMATCH (1) and $STR_REGEXPARRAYFULLMATCH (2) find the first match and return captured groups in an array; when the pattern has no capturing groups, the first match is returned in the array.
$STR_REGEXPARRAYGLOBALMATCH (3) and $STR_REGEXPARRAYGLOBALFULLMATCH (4) fill the array with all matching instances.

$STR_REGEXPARRAYMATCH returns an array of matches while $STR_REGEXPARRAYFULLMATCH returns an array of matches including the full match (Perl / PHP style).

$STR_REGEXPARRAYFULLMATCH and $STR_REGEXPARRAYGLOBALFULLMATCH include the full matching text as the first element of the return array, while $STR_REGEXPARRAYMATCH and $STR_REGEXPARRAYGLOBALMATCH only return the captured groups.

$STR_REGEXPARRAYGLOBALMATCH returns an array of global matches while $STR_REGEXPARRAYGLOBALFULLMATCH returns an array of arrays containing global matches including the full match (Perl / PHP style).

Here's how to see what each option does:

Local $aArray = 0

Local $sInput = "/kml/Document/name"

$aArray= StringRegExp($sInput, "(.+)\/",$STR_REGEXPARRAYMATCH)

_ArrayDisplay($aArray, "Option $STR_REGEXPARRAYMATCH")

$aArray= StringRegExp($sInput, "(.+)\/",$STR_REGEXPARRAYFULLMATCH)

_ArrayDisplay($aArray, "Option $STR_REGEXPARRAYFULLMATCH")

$aArray= StringRegExp($sInput, "(.+)\/",$STR_REGEXPARRAYGLOBALMATCH)

_ArrayDisplay($aArray, "Option $STR_REGEXPARRAYGLOBALMATCH")

$aArray= StringRegExp($sInput, "(.+)\/",$STR_REGEXPARRAYGLOBALFULLMATCH)

_ArrayDisplay($aArray, "Option $STR_REGEXPARRAYGLOBALFULLMATCH")

As a reference, here's how to perform the same kind of search with string functions:

Local $iPost = StringInStr($sInput, "/",$STR_NOCASESENSE , -1) ;Use a negative occurrence to search from the right side

ConsoleWrite(StringLeft ($sInput, $iPost-1)) ; -1 to ignore trailing /

Generating a random alphanumeric string

Func _MakeString()

Local $aSplit = StringSplit('abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '')

Local $sHoldString = ''

For $iCC = 1 To Random(10, 15, 1)

$sHoldString &= $aSplit[Random(1, 62, 1)]

Return $sHoldString

EndFunc

Generating a GUID

#include <WinAPICom.au3>

ConsoleWrite(_WinAPI_CreateGUID() & @CRLF)

Calling a function every x ms

AdlibRegister('_UpdateEdit', 1000)

...

Func _UpdateEdit()

Local $sMoreText = @YEAR & "/" & @MON & "/" & @MDAY & " " & @HOUR & ":" & @MIN & ":" & @SEC

GUICtrlSetData($idEdit, GUICtrlRead($idEdit) & @CRLF & $sMoreText)

_GUICtrlEdit_Scroll($idEdit, $SB_SCROLLCARET)

GUI

AutoIt can be used to write graphical applications. As of 2018, there are two ways to do this: Either by writing your own code directly, or by using any of the numerous GUI creators such as GuiBuilderPlus (under current development) or the Koda GUI designer — which is included in the AutoIt installer, but hasn't been updated since 2010. Note that GUI designers only handle the GUI, not the code of the application: Any change you make to the GUI must be retrofitted into the application.

Some sources to learn how to write GUIs in AutoIt:

"c:\Program Files\AutoIt3\Examples\GUI\"
Help file: GUI Reference, Function Reference > GUI Management, UDF > GUI References

AutoIt 1-2-3 (Last updated November 28, 2007)
https://www.autoitscript.com/forum/forum/10-autoit-gui-help-and-support/

AutoIt supports the following widgets:

Label
Button
Input
Edit
Checkbox
Radio
Combo
List
Date
Pic
Icon
Progress
Tab
UpDown
Avi
Menu
ContextMenu
TreeView
Slider
ListView
ListViewItem
Graphic

Basic GUI functions

GUICreate Create a window.
GUISetState Display or hide the window.
GUICtrlCreate... Create various controls in a window.
GUICtrlSetData Set/change the data in a control.
GUICtrlRead Read the data in a control
GUICtrlUpdate... Change various options for a control (color, style, etc.)
GUIGetMsg Poll the GUI to see if an event has happened (MessageLoop mode only)

Handling Events

Two ways to handle events: MessageLoop mode (default; actively polls the GUIGetMsg function; best for GUIs where the GUI is "king" and all you care about is waiting for user events) and OnEvent mode (enabled with Opt("GUIOnEventMode", 1); best for GUIs where the GUI is of secondary importance and your script has other tasks to perform in addition to looking after the GUI).

MessageLoop

While True

$nMsg = GUIGetMsg()

Switch $nMsg

Case $GUI_EVENT_CLOSE

Exit

Case $OK

MsgBox($MB_OK, "GUI Event", "You selected OK!")

Case $Cancel

MsgBox($MB_OK, "GUI Event", "You selected Cancel!")

EndSwitch

WEnd

OnEvent

Opt("GUIOnEventMode", 1) ; Change to OnEvent mode

Local $hMainGUI = GUICreate("Hello World", 200, 100)

Local $iOKButton = GUICtrlCreateButton("OK", 70, 50, 60)

GUICtrlSetOnEvent($iOKButton, "OKButton")

GUISetOnEvent($GUI_EVENT_CLOSE, "CLOSEButton")

GUISetState(@SW_SHOW, $hMainGUI)

While True

Sleep(100) ; Sleep to reduce CPU usage

WEnd

Func OKButton()

; Note: At this point @GUI_CtrlId would equal $iOKButton,

; and @GUI_WinHandle would equal $hMainGUI

MsgBox($MB_OK, "GUI Event", "You selected OK!")

EndFunc ;==>OKButton

Func CLOSEButton()

; Note: At this point @GUI_CtrlId would equal $GUI_EVENT_CLOSE,

; and @GUI_WinHandle would equal $hMainGUI

MsgBox($MB_OK, "GUI Event", "You selected CLOSE! Exiting...")

Exit

EndFunc ;==>CLOSEButton

Basic loop

Here's how to create the GUI, perform some tasks, and then wait until the user hits the Esc key to close the app:

; Create GUI

Local $hGUI = GUICreate("Blah", 400, 300)

...

; Loop until the user exits.

Until GUIGetMsg() = $GUI_EVENT_CLOSE

GUIDelete()

#include <ButtonConstants.au3> Button, Group, Radio, Checkbox
#include <ComboConstants.au3> Combo

#include <TabConstants.au3> Tab
#include <TreeViewConstants.au3> TreeView
#include <UpdownConstants.au3> Updown
#include <WindowsConstants.au3> Gui extended style

Edit box

Using the third option is used and setting it to "1" puts the carret at then end before appending text.

Use this to include a vertical scroll bar:

Local $aWindowClientArea_Size = WinGetClientSize($gui)

Local $EditBox = GUICtrlCreateEdit("", -1, -1,$aWindowClientArea_Size[0],$aWindowClientArea_Size[1],BitOR($ES_MULTILINE,$ES_READONLY,$WS_VSCROLL,$ES_AUTOVSCROLL))

Here's how to empty controls by relying on the fact that each control is assigned an integer that is incremented with each time control:

#include <WindowsConstants.au3>

#include <WinAPI.au3>

For $i=$FIRST to $LAST

if _WinAPI_GetClassName(GUICtrlGetHandle($i))="Edit" Then

GUICtrlSetData($i,"")

EndIf

Input box

Move caret to the beginning:

GuiCtrlSendMsg($INPUTCTRL, $EM_SETSEL, 0, 0)

Checkboxes

$sOptions = ((GUICtrlRead($BITRATE) = $GUI_CHECKED) ? "-b:v 450k ": "")

Radio buttons

The GUICtrlCreateGroup() assumes that widgets that follow belong to the group, with no need to specify the group's handle. The group will take of selecting/unselecting the buttons:

$Group1 = GUICtrlCreateGroup("My group", 8, 8, 113, 81)

$Blah = GUICtrlCreateRadio("Blah", 16, 24, 57, 25)

A simple way to check which of two buttons is selected:

$Choice = (GUICtrlRead($Blah) = $GUI_CHECKED) ? "Choice1" : "Choice2")

Launch long-running task

To keep the GUI responsive while launching a long-running task:

#include <GDIPlus.au3>

#include <GUIConstantsEx.au3>

#include <GUIListBox.au3>

#include <WindowsConstants.au3>

#Region ### START Koda GUI section ### Form=

$Form1 = GUICreate("Form1", 623, 449, 279, 114)

$List1 = GUICtrlCreateList("", 0, 52, 622, 396)

GUISetState(@SW_SHOW)

#EndRegion ### END Koda GUI section ###

For blah

Centering the window

Don't specify the "left,top" params, or even the "width,heigh":

$Form1 = GUICreate("Blah", 397, 357)

Simple GUI loop just to keep window open

Simplest code:

While GuiGetMsg() <> $GUI_EVENT_CLOSE
WEnd

Alternative:

$idMsg = GUIGetMsg()

If $idMsg = $idButton Then

;do stuff

EndIf

Until $idMsg = $GUI_EVENT_CLOSE

Don't use Sleep in an inner loop. According to the help file, a call to sleep() isn't necessary since GuiGetMsg() " automatically idles the CPU when required so that it can be safely used in tight loops without hogging all the CPU."

While True

$nMsg = GUIGetMsg()

Switch $nMsg

Case $OK

While True

;So Cancel works while busy here

$nMsg = GUIGetMsg()

if $nMsg = $GUI_EVENT_CLOSE or $nMsg = $Cancel Then ExitLoop

Plain window to output text

The window contains a single widget, just to output text:

#Region #GUI section

Local $gui = GUICreate("Test", 360, 333)

ControlSetText("", "", $gui, "New title")

Local $aWindowClientArea_Size = WinGetClientSize($gui)

Local $EditBox = GUICtrlCreateEdit("", -1, -1,$aWindowClientArea_Size[0],$aWindowClientArea_Size[1],bitor($ES_MULTILINE,$ES_READONLY,$ES_AUTOVSCROLL))

GUISetState()

#EndRegion

While True

if GUIGetMsg() = $GUI_EVENT_CLOSE Then ExitLoop

GUICtrlSetData($EditBox, ControlGetText("","",$EditBox) & ".")

WEnd

This works, but it doesn't close when the user hits the Escape key, and doesn't support MsgBox():

SplashTextOn($SPLASH_TITLE, "", -1, -1, -1, -1, $DLG_TEXTLEFT, "", 24)

Local $iReturn = Run($LINE, $WORKDIR, @SW_HIDE,$STDOUT_CHILD + $STDERR_CHILD)

If @error Then Exit MsgBox($MB_ICONERROR, "Error", "Run failed." & @CRLF & @CRLF & StderrRead($iReturn))

While True

ControlSetText($SPLASH_TITLE, "", "Static1", $iIndex )

WEnd

ConsoleWrite("Done." & @CRLF)

Sleep(1000)

SplashOff()

Working with COM libraries

The Help file contains two sections: "Obj/COM Reference", and "Obj/COM functions Reference". Since they're not part of AutoIt, and hence auto-completion isn't available, working with COM objects requires reading their respective documentations to figure things out.
In addition to Obj*() and IsObj(), AutoIt provides two extra syntaxes to make things easier: With..EndWith, and For..In (the latter can also be used with AutoIt's arrays, not just COM objects; The For..In syntax is needed to enumerate a collection's elements).

$oXmlDoc = ObjCreate("Microsoft.XMLDOM")

If @error Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "COM Error", "@error = 0x" & Hex(@error)))

If IsObj($$oXmlDoc) Then

With $oXmlDoc

.mymethod($blah)

If .parseError.errorCode Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "Some error", .parseError.reason)

EndWith

EndIf

;Enumerate a collection of objects

For $iCell In $oExcel.ActiveSheet.Range("A1:O16")

;blah

There are two ways to handle COM errors: Using a generic error function by AutoIt, or the object's specific events.

Local $oComErr = ObjEvent("AutoIt.Error", "com_error_handler")

#forceref $oComErr

...

Func com_error_handler($oError)

With $oError

ConsoleWrite(@CRLF & "COM ERROR DETECTED!" & @CRLF)

ConsoleWrite(" Error ScriptLine....... " & .scriptline & @CRLF)

ConsoleWrite(" Error Number........... " & StringFormat("0x%08x (%i)", .number, .number) & @CRLF)

ConsoleWrite(" Error WinDescription... " & StringStripWS(.windescription, $STR_STRIPTRAILING) & @CRLF)

ConsoleWrite(" Error RetCode.......... " & StringFormat("0x%08x (%i)", .retcode, .retcode) & @CRLF)

ConsoleWrite(" Error Description...... " & StringStripWS(.description , $STR_STRIPTRAILING) & @CRLF)

EndWith

Exit

EndFunc

Not all Object support events, if any. AutoItCOM can only receive 'dispatch' type events. Also, you need to know the names of the Events the Object could generate, including their arguments. Here's an example:

Local $oEventObject = ObjEvent($oIE, "IEEvent_", "DWebBrowserEvents") ; Start receiving Events.

...

Func IEEvent_StatusTextChange($sText)

...

EndFunc ;==>IEEvent_StatusTextChange

Func IEEvent_BeforeNavigate($sURL, $iFlags, $sTargetFrameName, $dPostData, $sHeaders, $bCancel)

...

EndFunc ;==>IEEvent_BeforeNavigate

COM objects are automatically released when the script exists, but they can be released manually by assiging a value of zero:

Local $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") ; Object is created

$oHTTP = 0 ; Object is deleted

The "OLE/COM Object Viewer" (more infos) is a handy tool to get a peek on all COM libraries currently installed on your system. By default, oleview.exe will be installed in C:\Program Files\Resource Kit\. It requires downloading the IVIEWERS.DLL file separately.
Surprisingly, the OLE/COM Object Viewer application doesn't provide a search function: To find an object, you'll have to manually look it up in the Type Libraries section, eg. "Microsoft XML" — start typing to find an object. Right-clicking can copy its GUID into the clipboard, which can then be looked for in the Registry.

The "VersionIndependentProgID" info is to be used when calling Obj*().

"AutoIt uses the IDispatch interface for automation. This interface 'exposes' all scriptable methods and properties that the object supports. If there is no IDispatch interface for an object, you can't use the object in an AutoIt script." Note: For some reason, the application returns this error when right-clicking on an object's IDispatch interface: "IDataObject interface viewer only supports IID_IDataObject.

Some information about the Viewer is available in the help file's "Obj/COM Reference" section.

Working with XML/HTML files

As of 2023, the best solution is to work directly with Microsoft's MSXML COM server through AutoIt's ObjCreate(). mLipok's XML.au3 UDF wrapper (Previously XMLWrapperEx.au3) to Microsoft.XMLDOM (msxmlX.dll is currently at version 6) is incomplete and hasn't been updated since 2017. If you don't need to save changes back to XML, TheXman's jq.au3 can convert XML to JSON using jq.exe.

Important: If search fails even though the XPath is correct, it could be due to namespaces. To check, either get rid of them in the input file, or use a regex for that purpose — StringRegExpReplace(FileRead($XML_FILE), "(xmlns:?[^=]*=[""][^""]*[""])", "") .

List of UDF's:

Using the MSXML COM server

If you don't know how to work with XML, it can't hurt to first read a bit about MSXML and DOM, along with XPath.

Reading and searching

$sXML = FileRead("your.xml")

Local $oXML = ObjCreate("Microsoft.XMLDOM")

$oXML.loadxml($sXML)

$oIncidents = $oXML.SelectNodes("//TrafficIncident")

For $oIncident In $oIncidents

$oLatitude = $oIncident.SelectSingleNode("./Point/Latitude")

ConsoleWrite($oLatitude.text & @CRLF)

Catching errors

; Error monitoring. This will trap all COM errors while alive.
; This particular object is declared as local, meaning after the function returns it will not exist.
Local $oErrorHandler = ObjEvent("AutoIt.Error", "_ErrFunc")

Func _ErrFunc($oError)

; Do anything here.

ConsoleWrite(@ScriptName & " (" & $oError.scriptline & ") : ==> COM Error intercepted !" & @CRLF & _

@TAB & "err.number is: " & @TAB & @TAB & "0x" & Hex($oError.number) & @CRLF & _

@TAB & "err.windescription:" & @TAB & $oError.windescription & @CRLF & _

@TAB & "err.description is: " & @TAB & $oError.description & @CRLF & _

@TAB & "err.source is: " & @TAB & @TAB & $oError.source & @CRLF & _

@TAB & "err.helpfile is: " & @TAB & $oError.helpfile & @CRLF & _

mLipok's XML.au3 UDF

As of 2023, the latest release is 1.1.1.13 from March 2017. It requires including xml.au3 and ADO_CONSTANTS.au3. _XMLDomWrapper_1.0.3.98_CN.au3 is only included for historical reference.

Sources to learn:

Comments in the actual UDF: XML.au3
XML__Examples_*.au3 in the ZIP
This thread in the forum (the code in the first half sometimes no longer works due to changes made later)
Threads in the Help forum that contain "xml" in their subject (it doesn't allow searching for "_XML_") and sort by date to ignore questions asked before the UDF was published
the Microsoft.XMLDOM doco

Before asking for help in the thread, make sure you use the latest release of the UDF, and provide the versions of msxmd.dll, the UDF, AutoIt, and SciTE you're using. If you get a "Automation server can't create object", make sure msxml.dll is actually installed, and up to date.

To find data, use XPath to the max.

That UDF might be good enough for your needs, although development stopped in 2017, and some functions are either not as easy to use as they should be, or missing altogether:

Can't use pointer from _XML_SelectSingleNode to get/set value; Apparently, can only be used with _XML_GetNodeAttributeValue()
_XML_GetValue() returns an array instead of a string like $oNode.Text
Why two functions: _XML_UpdateField() and _XML_UpdateField2()?
_XML_CreateChildNode is not implemented
CHECK appendChild() is not implemented
_XML_GetParentNodeName() returns nothing
No function to navigate to sibbling?
_XML_CreateFile creates a file… that can't then be used with _XML_SaveToFile(); Must only be used to create and save a file in a single call, as changes made later aren't saved. Use _XML_CreateDOMDocument() +_XML_CreateRootNode() + _XML_SaveToFile() instead
etc.

Since multiple UDFs were written over time, I assume working with MSXML exclusively through a COM object is much harder — or people wouldn't have bothered. Regardless, since XML is getting a bit old, an alternative could be to convert XML to JSON, and use JSON functions instead.

Functions

A function returns either OK/NOK, a string, an array, or a collection — a collection might need to be turned into an array before further use (after always checking for for success/error) eg. _XML_GetAllAttribIndex() + _XML_Array_GetAttributesProperties().

Check UDF version
