Is there any way of instantiating the "chakra.dll" in the form of an object?
something similar to as described here (but for C#), where this command 'host = new ChakraHost();" is used to instantiate Chakra as an object, and then the dot notation syntax is used to call the methods 'host.CallFunction("commitFunction");'  ......?

I think that would require wrapping the functions in some kind of COM object (AutoItObject for example), since ChakraCore.dll exposes only "flat API", i.e. exported DLL functions. ("Note that JSRT APIs are C++ APIs, this sample assumes a C# wrapper.", as it says on the Embedding ChakraCore page).

Hi @scintilla4evr, thanks for your answer

I was wondering if what says @guinness  in his topic here, could be used with this chakradll as well..?

anyway, back on your udf, could you show how to use it if, for example, I would like to use the functions from this 'moment' javascript library directly from AutoIt? (library found on this nice site)

any example is welcome

Thank You :)

Help a poor newbie !

Congratulations, but

I can't find out what's wrong with chakracore.au3  when calling a quite basic execution on the example 1 mode :

(function() {
    var h = window.document.location.href ;
    return h ;
})();

Many thanks in advance.

Func _ChakraCore_Startup($sDllFile = "Chakra.dll")

I had to remove the core part from the dll name and then it works. Powefull extension

My output from the examples

  1. JavaScript Output: 5
  2. JavaScript Output: 13
  3. JavaScript Output: llo Wor
  4. JavaScript Output: Lorem ipsum dolor sit amet
  5. a: 320

Sorry for such a GIGANTIC delay in answering this question.

You can't use window.document.<blah blah insert some object here> in ChakraCore, because the window object is exposed only by web browsers. This UDF only gives access to "raw" JavaScript, so there are no browser-specific objects - no window, navigator, DOM, etc.

      Hello,
      as a start in Autoit i tried something i was missing since im using Autoit. 

      I build a custom MessageBox which has a large amount of custom options and which scales its size on the parameters you set. 

      Aviable Settings:
      -Title
      -Unlimited Buttons
      -Text Color (Buttons, Text)

      -Background Color (Msgbox, Buttons, Label) 

      -Button Timeout
      -Autoclose Timeout
      -Icon (Default, No Icon, Custom)

      -Label/ Button Style. 
      -Transparency

      I tried to keep this as close as i could to a Msgbox i was used too on my batch times.

      After i was ready i realised, @Melba23 probably build a way better msgbox which would have suit my needs enterly, anyway thanks to @Melba23 because i use his Stringsize UDF. 

       
       
      local $Message = _sMsgBox("Test", 6, "Continue?") if @extended <> -1 Then MsgBox(0, @extended, $Message&" Button pressed")

      Dear members, 
      I am working on a project where, emails from outlook are to be read and moved to various folders within the mailbox, based on the content of the emails.
      I used the below code for moving mails. It works fine when I run it against individual mail ids. But when I run it on Shared mailbox, the mails are not moved to respective folders.
      _OL_ItemMove($oOutlook, $sEntryId, Default, $sDestinationFolder) The value of $sEntryId is saved in an excel report initially. The current process reads the $sEntryId from the excel and passes it to "_OL_ItemMove" statement.
      Requesting the guidance of the forum members in this issue.

      Good evening everyone
      I am working with Word UDF ( thanks @water! ), and, especially, with the function _Word_DocFindReplace().
      The replace does work everywhere in the document, but, it does not work in Headers or Footers.
      Am I missing something or am I forced to use the code below?
      I have already looked in the Help file ( about _Word_DocFindReplace() ), but there are no mentions about replace text in Headers/Footers.
      Sub FindAndReplaceFirstStoryOfEachType() Dim rngStory As Range For Each rngStory In ActiveDocument.StoryRanges With rngStory.Find .Text = "find text" .Replacement.Text = "I'm found .Wrap = wdFindContinue .Execute Replace:=wdReplaceAll End With Next rngStory End Sub Thanks everyone in advance


      Best Regards.

      Is there a way to grab non-hardcoded but rather javascript generated data from a webpage?
      Tried a get request as well as _IEBodyReadHTML but both seem to grab the code without the javascript generated data.
      $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") $oHTTP.Open("GET", "link", False) $oHTTP.Send() $oReceived = $oHTTP.ResponseText $oStatusCode = $oHTTP.Status Global $DataArray[10][5] If $oStatusCode <> 200 Then Exit MsgBox(1, "Error", "Status Code <> 200") EndIf FileWrite(@ScriptDir & "\output.txt", $oReceived) ; //////// #include <IE.au3> Local $FullLink = "link" Local $oIE = _IECreate($FullLink, 0, 0) _IELoadWait($oIE) Local $sText = _IEBodyReadHTML($oIE) FileWrite(@ScriptDir & "\output.txt", $sText)

      I noticed a lack of a constants file for _WinAPI_GetSystemMetrics() so I made this for anyone who wants to add it to their library. Enjoy!  (file attached below)
