Extract it, compile...

I run it from SciTE. It runs just fine.

Thanks for the answers,
... if I compile the script all is fine, but if i don't compile and i just run it from SciTE (F5) i get the error as in obove posts, and this is what i would like to avoid if possible (would be interesting to understand why for someone it works from SciTE and for others (or at least for me) it doesn't... 😕

But where should I put these libraries to be able to run the script from SciTE without having to compile it every time I make a change?

You can try to copy WebView2Loader-x86.dll and WebView2Loader-x64.dll to the AutoIt installation folder. When you run a program in SciTE with F5 then either AutoIt3.exe or AutoIt3_x64.exe is the running executable.

I completely agree with you that it's inappropriate especially during program development that one cannot run the code directly from SciTE.

The reason why you cannot run the code from SciTE must probably be found on your own PC. argumentum, mLipok and I can actually run the code from SciTE on our PCs.

Thank you @LarsJ for your suggestion
I copied the dlls into the autoit path, but again without success, however I think I have found the reason for the problem:
1) after copying the 2 dll to the autoit path, the error kept occurring
2) I tried to set #RequireAdmin on the script and, at this point, the following new error window appeared:

"Microsoft Edge cannot read and write to the data directory:
C:\ Program Files (x86) \ AutoIt3 \ autoit3_x64.exe.WebView2 \ EBWebView"

so the problem is that the AutoIt3 directory doesn't have write permission for local users.
That's all. it is not necessary to copy the DLLs to a location other than the script path.

my solution has been to set write/modify permissions to the AutoIt3 folder so to allow the script to create its own subfolder (on first run).
Once the subfolder was created, I restored the previous permission to the AutoIt3 folder and allowed the write/modify permission only to the newly created autoit3_x64.exe.WebView2 folder
This way everything works fine (... so far ...)

Thanks again for your tips

P.S.

@LarsJ This WebView2 script you wrote is elite. I tried to study it and I see that you have for example also used portions of code (Func ObjectFromTag) that I had already seen (with awe) created by the queen of developers @trancexx in this other post.
But, now as then I must give up trying to understand. This type of code intimidates me, too complex for my poor understanding of the inner workings of Windows.
However I like to see powerful code like this appear on the forum thanks to programmers, like you and many others, who master these intricacies with great ease.

Thanks again

Chimp, That's super debugging. We had the exact same problem a few years ago as discussed in this and the next many following posts related to .NET assembly dll-files. Your solution will in all likelihood also be the solution to this problem.

The code is translated to AutoIt from the C++ code in the Getting started example step 4, from the C++ code in ICoreWebView2.add_NavigationStarting() and from the AutoHotkey code in WebView2.ahk.

In case of a CreateCoreWebView2EnvironmentWithOptions ERR in the SciTE console then the cause of the problem and the solution is described by Chimp in this post above.

WebView2.h, HelloWebView.cpp and the three dll-files contained in the 7z-file are copied from the NuGet package needed to compile the C++ Getting started example.

Examples:

WebView2-1.au3: Getting started example step 3: WebView window
WebView2-2.au3: Getting started example step 4: Navigation events (this example)
WebView2-3.au3: AutoIt implementation of the AutoHotkey example
WebView2-4.au3: Scripting example based on code by Chimp
WebView2-5.au3: Getting started example step 5: Scripting
WebView2-6.au3: Getting started example step 6: Communication (doesn't work)

Hi LarsJ,

Based on @mLipok example.

You can add this to the examples :

HotKeySet("^+I", "DevTools") ; CTRL+SHIFT+I

;....

Func DevTools()
    $oCoreWebView2.OpenDevToolsWindow()
EndFunc

To make it compliant with the Edge standard.

Still missing an address bar and buttons to make it complete 😉

just doing some "random" (a bit messy) tests to get familiar, modifying the scripts of the examples; I placed a mini WebView on the GUI and tried to stress the "NavigateToString" method by passing an old html source for fun. I also placed a button on the GUI to try to use "ExecuteScript", but obviously it shouldn't be used this way, in fact the script fails. Anyone have an example of how to use "ExecuteScript"? More than trying to mimic a browser, I'm interested in being able to interact with the page content in the WebView. Thanks in advance to anyone who wants to help

@Chimp the LED animation is awesome.

btw.
Did you try:
$oCoreWebView2.PostWebMessageAsString(.....)

and
$oCoreWebView2.ExecuteScriptAsync($sString) ; Method

??

When using the ObjCreateInterface() function, filling in method and property parameter types in the description tag string is the most time consuming job. The method and property names can be copied directly from the header file, WebView2.h, but the parameter types must be translated to corresponding AutoIt types. Therefore, in WV2Interfaces.au3 I've only filled in parameter types for the methods and properties that are actually used in the code. Since I've not used $oCoreWebView2.ExecuteScript() the parameter types are not filled in.

Replace at the top of WV2Interfaces.au3

"ExecuteScript hresult();"

with

"ExecuteScript hresult(wstr;ptr);"

Then replace in the code above

Case $Button1
  $oCoreWebView2.ExecuteScript("alert('Hello');")

with

Case $Button1
  $oCoreWebView2.ExecuteScript("alert('Hello');", NULL)
  Sleep(3000)
  $oCoreWebView2.NavigateToString(_GetPage())

or similar.

It works, but to see the results the window should be maximized so $GUI_EVENT_MAXIMIZE, $GUI_EVENT_RESIZED, $GUI_EVENT_RESTORE should be maintained

While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_MAXIMIZE, $GUI_EVENT_RESIZED, $GUI_EVENT_RESTORE
                Local $tRect = _WinAPI_GetClientRect($hGui)
                $oCoreWebView2Controller.put_Bounds($tRect)
            Case $Button1
                  $oCoreWebView2.ExecuteScript("alert('Hello');", NULL)
                  Sleep(3000)
                  $oCoreWebView2.NavigateToString(_GetPage())
            Case $GUI_EVENT_CLOSE
                ExitLoop
        EndSwitch

... the parameter types must be translated to corresponding AutoIt types.

well, I got it. Thanks for the illuminating explanation! :graduated:
So WV2Interfaces.au3 is still under construction. If I were able I could collaborate in compiling those parameters, but I'm afraid I would do more harm than good ...
I think this ExecuteScript function is very useful. I'm sorry, I hope I'm not too boring, but I would be interested in understanding how to set up for this function also the part related to receiving the result of the script that has been executed, that is; ExecuteScript(LPCWSTR javaScript, ICoreWebView2ExecuteScriptCompletedHandler *handler), so to be able to use the related callback function in our script.
Thanks so much again for any help

P.S.
In my previous post I've embedded in the script a quite long Html listing. Well, if someone is interested, I've used an easy and quick way to generate that ready to be pasted in the AutoIt script
1) Find the the HTML/Javascript listing that you want to embedd in your AutoIt listing and copy it to the clipboard. (that is select it and hit ctrl-c)
2) run this little snippet, It reads the listing that is in the clipboard, prepare it for the pasting and, after the tranformation, puts it again in the clipboard.

Local $sFuntionName = "_GetSource"
Local $sVarName = "$sSource"
Local $aStr = StringSplit(ClipGet(), @CRLF, 1) ;  get the clipboard content

Local $sListing = "Func " & $sFuntionName & "()" & @CRLF
$sListing &= 'Local ' & $sVarName & ' = ""' & @CRLF
For $i = 1 To $aStr[0]
    $sListing &= $sVarName & ' &= "' & StringReplace($aStr[$i], '"', '""') & '" & @CRLF' & @CRLF
Next
$sListing &= "Return " & $sVarName & @CRLF
$sListing &= "EndFunc"
ClipPut($sListing)
; ConsoleWrite($sListing)

3) paste the clipboard in your listing (hit ctrl-v)

have fun

The code is translated to AutoIt from the C++ code in ICoreWebView2.ExecuteScript() and from this example by Chimp.

Compared to the original script by Chimp the ICoreWebView2ExecuteScriptCompletedHandler callback interface is added to the code.

WebView2-4.au3 is included in the 7z-file at bottom of this post.

On 2/10/2021 at 4:46 PM, Chimp said:

So WV2Interfaces.au3 is still under construction

If the code here is to be a replacement for IE.au3, then I think we'll have to translate all C/C++ code in WebView2.h to AutoIt code in WV2Interfaces.au3.

I'll create a new post to document the implementation of callback interfaces.

Great! I'm starting to like this stuff a lot. Thanks @LarsJ

A quick and dirty little example of how this ExecuteScript method is very powerful, for example to manipulate the web page content on the fly:

replace the simple command "alert ('Hello');" from within the ExecuteScript in the listing

$oCoreWebView2.ExecuteScript( "alert( 'Hello' );", $pCoreWebView2ExecuteScriptCompletedHandler )

with this other

$oCoreWebView2.ExecuteScript("document.getElementsByTagName(""img"").item(0).insertAdjacentHTML('beforebegin', '<iframe width=""210"" height=""173"" style=""position: absolute; top: 50px; left: 10px;"" src=""https://www.youtube.com/embed/tgbNymZ7vqY?autoplay=1""></iframe>');", $pCoreWebView2ExecuteScriptCompletedHandler )

and we will add a YouTube movie on the page. (do not press the button multiple times or more overlapping videos will be added)

see you later...

I'm testing Getting started example step 6: Communication but it doesn't work. How should this JavaScript code that works in C++

webviewWindow->AddScriptToExecuteOnDocumentCreated(
  L"window.chrome.webview.addEventListener(\'message\', event => alert(event.data));" \
  L"window.chrome.webview.postMessage(window.document.URL);",
  nullptr);

be expressed in AutoIt?

Gianni · February 12, 2021

? about the syntax should be like this:

$oCoreWebView2.AddScriptToExecuteOnDocumentCreated("window.chrome.webview.addEventListener('message', event => alert(event.data)); window.chrome.webview.postMessage(window.document.URL);", Null)

sorry, edit after a check:
don't ask me why, but I've seen that it works if you remove the ".chrome.webview" part, that is, like this:

$oCoreWebView2.AddScriptToExecuteOnDocumentCreated("window.addEventListener('message', event => alert(event.data)); window.postMessage(window.document.URL);", Null)

Edited February 12, 2021 by Chimp

LarsJ · February 12, 2021

Now the JavaScript code works. But the Communication example still doesn't work. The Invoke method of the CoreWebView2WebMessageReceivedEventHandler callback interface isn't called and a COM error is generated when the script exits. For the time being, let's leave this problem alone.

The Getting started examples except the Communication example can be found in the 7z-file at bottom of this post.

Now we've more or less been through all the Getting started examples. How do we get on from here?
