Running AutoIt code from any web browser


Recommended Posts

  • 2 years later...

I'm finding this very useful, also for working with emails (Thunderbird)

For example, an automated report send me a mail, with html code generated like this

Local $oStream = ObjCreate("ADODB.Stream")
$oStream.Type = 2 ; adTypeText
$oStream.Charset = "utf-8"
$oStream.LineSeparator = -1 ; adCRLF
;StreamWriteEnum: 1 adWriteLine
$oStream.WriteText("<html>", 1)
$oStream.WriteText("<head>", 1)
$oStream.WriteText("<style>", 1)
$oStream.WriteText(".Menu li a:hover:not(.active) {background-color: #ddd;}", 1)
$oStream.WriteText("</style>", 1)
$oStream.WriteText("</head>", 1)
$oStream.WriteText("<body>", 1)

$oStream.WriteText("<ul class='Menu' style='list-style-type: none;margin: 0;padding: 0;overflow: hidden;border: 1px solid #e7e7e7;background-color: #f3f3f3;'>", 1)
$oStream.WriteText("<li style='float: left;'><a href='autoit:MyScript.a3x|\\MyServe\MyFolderPath\' moz-do-not-send='true' style='display: block;color: white;background-color: #4CAF50;text-align: center;padding: 5px 7px;text-decoration: none;'>Some Folder</a></li>", 1)
$oStream.WriteText("<li style='float: left;'><a href='#news' moz-do-not-send='true' style='display: block;color: #666;text-align: center;padding: 5px 7px;text-decoration: none;'>Another link</a></li>", 1)
$oStream.WriteText("</ul><br><br>", 1)

$oStream.WriteText("</body>", 1)
$oStream.WriteText("</html>", 1)
$oStream.Position = 0
$sBody = $oStream.ReadText


Here is a simplified version of your code: i prefer to allow only execution of pre-saved autoit files


#pragma compile(AutoItExecuteAllowed, true) ; Required!
#pragma compile(FileDescription, "AutoIt Protocol Handler")
#pragma compile(FileVersion,
#pragma compile(CompanyName, scintilla4evr)
#pragma compile(Icon, icon.ico)

If @Compiled Then
   Local $sData = StringTrimLeft($CmdLineRaw, 8)
   $sData = StringTrimRight($sData, 1)
   $sData = _URIDecode($sData)

   ;_RunAU3(".\scripts\AU3_Example.au3", $sData, @ScriptDir, @SW_SHOW, 8)
   ;in $sData there is a string with this format: AU3_Example.au3|parameter1 'parameter 2' ""parameter 3""
   Local $aArray = StringSplit($sData, "|")
   _RunAU3(".\scripts\" & $aArray[1], $aArray[2], @ScriptDir, @SW_SHOW, 8)

Func URLDecode($urlText)
    $urlText = StringReplace($urlText, "+", " ")
    Local $matches = StringRegExp($urlText, "\%([abcdefABCDEF0-9]{2})", 3)
    If Not @error Then
        For $match In $matches
            $urlText = StringReplace($urlText, "%" & $match, BinaryToString('0x' & $match))
    Return $urlText
EndFunc   ;==>URLDecode

;failed with ñ characters ¿unicode?
Func _URIDecode($sData)
    ; Prog@ndy
    ;Local $aData = StringSplit(StringReplace($sData,"+"," ",0,1),"%")
    Local $aData = StringSplit($sData,"%")
    $sData = ""
    For $i = 2 To $aData[0]
        $aData[1] &= Chr(Dec(StringLeft($aData[$i],2))) & StringTrimLeft($aData[$i],2)
    Return BinaryToString(StringToBinary($aData[1],1),4)

Func _RunAU3($sFilePath, $sParamet="", $sWorkingDir = "", $iShowFlag = @SW_SHOW, $iOptFlag = 0)
   Return Run('"' & @AutoItExe & '" /AutoIt3ExecuteScript "' & $sFilePath & '" "' & $sParamet & '"', $sWorkingDir, $iShowFlag, $iOptFlag)
EndFunc   ;==>_RunAU3



;Add necessary registry values & keys
RegWrite("HKCR\autoit", "", "REG_SZ", "URL:AutoIt Protocol")
RegWrite("HKCR\autoit", "URL Protocol", "REG_SZ", "")
RegWrite("HKCR\autoit\DefaultIcon", "", "REG_SZ", @AutoItExe&",1")
RegWrite("HKCR\autoit\shell\open\command", "", "REG_SZ", '"' & @ScriptDir & "\handler.exe" & '" "%1"')


Many Thaks!

Changed the url decode function because of 'ñ' characters

This is only an 'experiment', just for curiosity:

using the custom protocol to run AutoIt code from excel VBA and excel sheet formula (hyperlink)

First the formula example:

=HYPERLINK("autoit:MsgBox(0,'2+2',2+2)","Run AutoIt Code")

The same but from VBA using ActiveWorkbook.FollowHyperlink:

Sub Run_AutoIt_code_from_VBA_FollowHyperlink()
Dim sLink As String
sLink = "autoit:MsgBox(0,'2+2',2+2)"
ActiveWorkbook.FollowHyperlink sLink
End Sub

Using ShellExecute API function: this does not display the excel links alert message

#If VBA7 Then
    Public Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As LongPtr, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As LongPtr
    Public Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#End If

Sub Run_AutoIt_code_from_VBA_ShellExecute_Single_line()
Dim sCmd As String
sCmd = "autoit:MsgBox(0,'2+2',2+2)"
Call ShellExecute(0&, vbNullString, sCmd, vbNullString, vbNullString, vbNormalFocus)
End Sub

Sub Run_AutoIt_code_from_VBA_ShellExecute_Multi_line()
Dim sCmd As String
sCmd = "autoit:str-format($str = InputBox('Question', 'What''s your favorite color?')\nIf Not @error Then MsgBox(0, 'Answer', $str))"
Call ShellExecute(0&, vbNullString, sCmd, vbNullString, vbNullString, vbNormalFocus)
End Sub

The excel file with examples:

¿Is it possible to 'receive' the content of an htm form?

I mean the content of the html input boxes

I'm working with thunderbird html mail

For reference:

- Beating Thunderbird’s Checkbox Bug (and Targeting Techniques)


I noticed that clicking on any form element causes the form to be submitted. If the form has a url within an action attribute, the form is posted to that url.

<form id=f2 action="autoit:Some_Name.a3x">
 <label for=form-name>Name</label>
 <input name=form-name id=form-name type=text required><br>
 <label for=form-email>Email</label>
 <input name=form-email id=form-email type=email required><br>
 <label for=form-url>URL</label>
 <input name=form-url id=form-url type=url><br>
 <label for=form-comment>Comment</label>
 <textarea name=form-comment id=form-comment required></textarea><br>
 <input type=submit>


MsgBox(0, "Read Content from html form", StringSplit($CmdLine[1], "?")[2])

found by chance

But not possible from thunderbird mail
because form element has to be opened like:

<form action="#">

This is the form tested

<form id=form1 action="autoit:Read_form.au3|dummy">
<label form=form1 for=form-name>Name</label>
<input form=form1 type="text" id="text" name="text" value="Some text"><br>
<input form=form1 type=submit>

"In HTML5, a number of elements that were previously required to be within a form element<br>
(button, fieldset, input, label, select, textarea, etc.)<br>
can now be anywhere on the page and associated with a form using a form attribute pointing at the id of its form owner."<br>
