VB6 WebView2-Binding (Edge-Chromium)

[Schmidt]

The "scrambling" has already happened in this case
(meaning that the passed param uXML already contains "mangled" string-data).

Please check, where (and how) this uXML-param was retrieved (and then passed) -
and whether the proper decoding took place whilst filling it elsewhere.

It might also be, that the xml-header-string (as shown below, for UTF8-mode) -
points to a code-page, entirely different from UTF8... XML allows that...
(in which case, you shouldn't write it out as UTF8 via New_c.FSO.WriteTextContent).

The example code below shows, that when uXML is filled with proper Unicode,
the WebView2 can show Unicode-XML (in this case with a few german Umlauts), just fine.

Private WithEvents WV As cWebView2

Private Sub Form_Load()
  Visible = True

  Set WV = New_c.WebView2(hWnd)
 
  Dim uXml$: uXml = "<?xml version='1.0' encoding='UTF-8'?>" & vbCrLf & _
                    "<root><foo>" & ChrW(228) & ChrW(246) & ChrW(252) & _
                    "</foo><bar>" & ChrW(223) & ChrW(8364) & ChrW(248) & "</bar></root>"
               
  Const FileName = "c:\temp\simple.xml"
  
  New_c.FSO.WriteTextContent FileName, uXml, True
  WV.Navigate FileName
End Sub

How could I deserialize "Result"?

This does not compile and throws an Argument Byref Invalid error:

Set Elements = New_c.JSONDecodeToCollection(Result)

Private Sub WV_JSAsyncResult(Result As Variant, ByVal Token As Currency, ByVal ErrString As String)

    Debug.Print ErrString
    
    If Not Token = m_Token Then
        Exit Sub
    End If
    
    If IsEmpty(Result) Then
       Exit Sub
    End If
    
'retrieve a few elements "by selector-expression"
    Dim Elements As cCollection
  Set Elements = New_c.JSONDecodeToCollection(Result)

This is my JS code:

async function getActiveLinks() {
	let linksArray  = [];

	let linksSource = Array.from(document.querySelectorAll("a, area, button, select, textarea, object, input:not([type=\"hidden\"]), [role=link], [role=button], [role=combobox], [role=option], [role=textbox], [role=checkbox], [role=menuitem]"));

	for (let i = 0; i < linksSource.length; i++) {
		if (await isElelementVisible(linksSource[i], true, true)) {
			let text = await getTextValue(linksSource[i]);
			if (text.length > 0) {
				linksArray.push({
					text : text,
					vsnID: linksSource[i]._vsnEsureId()
				});
			}
		}
	}

		try {
                                          let thestring=JSON.stringify(linksArray);
                                          alert(thestring);
			return thestring;
		} catch (e) {
			alert(e);
		}

}

And if I try this...

Dim s$
s = Result

VB6 tells me error 447: "Object does not support the current language setting"

How could I deserialize "Result"?

This does not compile and throws an Argument Byref Invalid error:

Set Elements = New_c.JSONDecodeToCollection(Result)

Please try explicit conversion of the Variant Result to a String:
Set Elements = New_c.JSONDecodeToCollection(CStr(Result))

The VB6-compiler is a bit picky in this case, because both -
Result is a "ByRef" Param and JSONDecodeToCol(...) also expects a ByRef As String argument)

In other words, VB6 would not have any complaints about passing -
e.g. a Variant-Return-Result of a VB-Function (like e.g. WV.jsRun()) into the JSONDecode-Byref argument directly.

Here is an example, which works (showing async Result-Handling)

Option Explicit

      .AddNL "function setElementBackgroundById(id, color){"
      .AddNL "    document.querySelector('#'+id).style.background = color"
      .AddNL "}"

  End With
  
  With New_c.StringBuilder 'two anchors and two buttons as test-HTML-content

    .AddNL "<a id='a2' href='#bar'>LinkBar</a><br>"
    .AddNL "<input id='b2' type='button' value='button 2'><br>"
    
    WV.NavigateToString .ToString
  End With
  
  Set AsyncTokens = New_c.Collection(False)
  'retrieve a few elements asynchronously "by selector-expression"
  AsyncTokens.Add "getElements", WV.jsRunAsync("getElements", "a, input")
End Sub
 
Private Sub WV_JSAsyncResult(Result As Variant, ByVal Token As Currency, ByVal ErrString As String)
  If Not AsyncTokens.Exists(Token) Then Exit Sub

  Dim JobType As String: JobType = AsyncTokens(Token): AsyncTokens.Remove Token
  Select Case LCase$(JobType)
    Case "getelements"
      Set Elements = New_c.JSONDecodeToCollection(CStr(Result))
      
      Dim Elmt As cCollection 'the enumerated Elements themselves are (again) of type cCollection - but hold a JSON-Object instead of a JSON-array
      For Each Elmt In Elements 'iteration over the gathered Element-Objects in the JSON-Array: Elements

         Select Case UCase$(Elmt("tag")) 'first Property-access on an Element (here the "tag"-Property)
           Case "A":     WV.jsRun "setElementBackgroundById", Elmt("id"), "#f00"
           Case "INPUT": WV.jsRun "setElementBackgroundById", Elmt("id"), "#0f0"
         End Select
      Next
  End Select
End Sub

The other error you'getting is probably related, to not returning a String (but a COM-wrapped js-Object).
Please ensure, that you also return a String in case of an Error... (from your js-Functions - e.g. via return e.message in the catch-branch).
It is then relatively easy, to check whether the first char of such a String is either "{" or "[" == a JSON-String ... otherwise an error-string.

how to get text from xpath:

Function GetXpathText(Xpath As String) As String
    Dim js As String
    js = "document.evaluate(""" & Xpath & """, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.innerText"
    GetXpathText = Web1.jsProp(js)
End Function

 Dim js As String
    js = "document.evaluate(""" & Xpath & """, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.innerText"
 js = "alert(" & js & ")"

 
Web1.ExecuteScript js

alert is ok,but jsProp err,why?

Function GetXpathText(Xpath As String) As String
    Dim js As String
    js = "var XPathText=document.evaluate(""" & Xpath & """, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.innerText"
    Web1.ExecuteScript js
doevents
    GetXpathText = Web1.jsProp("XPathText")
End Function

'Web1.jsProp("XPathText.innerText")
Function GetTextByXpath(Xpath As String, Optional Method As String = ".innerText") As String
    Dim js As String
    js = "var XPathText=document.evaluate(""" & Xpath & """, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue"
    Web1.ExecuteScript js
doevents
    GetTextByXpath = Web1.jsProp("XPathText" & Method)
End Function

Is there a built-in method or more efficient technology that can run this?

Using my old browser, I defined a callback object (a COM dll) and a sub which would be called by the JS.

Can you tell me how I would do that with your browser? This is mycode:

async function exportChatAsXMLHelper(params){
	let displayname 	= params[0];
	let includeMedia 	= params[1];
	let debug 			= params[2];
	
	let xml = await exportChatAsXML(displayname, includeMedia, debug);

	//where is JSCallbackReceiver defined? it is from vb6
	window.JSCallbackReceiver.OnWhatsAppXMLReceived(xml);
}

async function exportChatAsXML(displayname, includeMedia, debug){
	//displayname, includeMedia, debug

    let chat = (await WPP.chat.list()).find(m => m.contact && m.contact.name && m.contact.name.includes(displayname));
    await WPP.chat.openChatBottom(chat.id);
    let msgs = await WPP.chat.getMessages(chat.id, {count : -1});

    const log = (obj) => debug && console.log(obj);

    log('Total messages: ' + msgs.length);

    let xml = '';

    xml+= '<messages>';

    for (var i = 0; i < msgs.length; i++) {
        log('Message number: ' + i);

        let message = msgs[i];
        xml+= '<message>';
        xml+= '<sender>'+ message.from.user +'</sender>';
        xml+= '<receiver>'+ message.to.user +'</receiver>';

        xml+= '<type>'+ (message.type || '') +'</type>';

        if(message.type == 'chat'){
            xml+= '<body>'+ message.body +'</body>';
        }

        if(message.type != 'chat' && includeMedia) {

            xml+= '<caption>'+ (message.caption || '') +'</caption>';
            xml+= '<filename>'+ (message.filename || '') +'</filename>';

        }

        xml+= '</message>';
    }

    xml+= '</messages>';

    return xml;
}


//-----
async function mediatoBase64(msgid) {
    let blob = await WPP.chat.downloadMedia(msgid);
    return new Promise((resolve, _) => {
        const reader = new FileReader();
        reader.onloadend = () => resolve(reader.result);
        reader.readAsDataURL(blob);

Could you tell me how I would call this from VB6?

async function exportChatAsXMLHelper(params){
	let displayname 	= params[0];
	let includeMedia 	= params[1];
	let debug 			= params[2];
//alert(displayname);
	await exportChatAsXML(displayname, includeMedia, debug);
}
async function exportChatAsXML(displayname, includeMedia, debug)
{
    let chat = null;
    if(displayname != ''){
        chat = (await WPP.chat.list()).find(m => m.contact && m.contact.name && m.contact.name.includes(displayname));
    } else {
        chat = (await WPP.chat.list()).find(m => m.active);
    }
    await WPP.chat.openChatBottom(chat.id);
    let msgs = await WPP.chat.getMessages(chat.id, {count : -1});

    const log = (obj) => debug && console.log(obj);

    //alert(msgs.length);

    log('Total messages: ' + msgs.length);

    let count=msgs.length;

    for (var i = 0; i < count; i++) {
        log('Message number: ' + i);

        let message = msgs[i];
        let xml='';
        xml+= '<message>';
        xml+= '<sender>'+ message.from.user +'</sender>';
        xml+= '<receiver>'+ message.to.user +'</receiver>';

        xml+= '<type>'+ (message.type || '') +'</type>';

        if(message.type == 'chat')
        {
            xml+= '<body>'+ message.body +'</body>';
        }

        if(message.type != 'chat' && includeMedia)
        {
            xml+= '<media>';
            xml+= '<caption>'+ (message.caption || '') +'</caption>';
            xml+= '<filename>'+ (message.filename || '') +'</filename>';

            log('Downloading media');

            try
            {
                let mediabody = await mediatoBase64(message.id);
                xml+= '<MediaDownloadStatus>success</MediaDownloadStatus>';
                xml+= '<base64>'+ mediabody +'</base64>';
            }
            catch(e)
            {
                xml+= '<base64></base64>';
                xml+= '<MediaDownloadStatus>fail</MediaDownloadStatus>';
            }
            xml+= '</media>';
        }

        if (i>50)
        {
             //alert('exit!');
           // break;
        }

        xml+= '</message>';

        //where is JSCallbackReceiver defined? it is from vb6
       TheApp.OnWhatsAppXMLReceived(xml,i, count);
       xml='';
    }
  //  xml+= '</messages>';
  //  return xml;
}

I have tried this, but it threw an "Object not defined" error:

WV.CallByName Array(sChatName, True, False), "exportChatAsXMLHelper", VbSet

Public Sub OnWhatsAppXMLReceived(ByVal xml As String, ByVal index As Long, ByVal max As Long)

End Sub

Public Sub OnWhatsAppXMLReceived(ByVal xml As String, ByVal index As Long, ByVal max As Long)

End Sub

Not sure, why you're using WV.CallByName, when it was already established,
that js-functions shall be called via either:
- WV.jsRun( "someJsFunction", ..., ... ) or
- WV.jsRunAsync "someOtherFunc", ..., ...

Also cannot deduce the purpose of your intermediate function (exportChatAsXMLHelper) -
you can call the main-routine perfectly fine (with its 3 arguments) via e.g. WV.jsAsync...

Here is an example again:

Option Explicit

Private WithEvents WV As cWebView2, Elements As cCollection
 
Private Sub Form_Load()
  Visible = True
  Set WV = New_c.WebView2(hWnd)
      WV.AddObject "TheApp", Me
      
  With New_c.StringBuilder
      .AddNL "async function exportChatAsXML(displayname, includeMedia, debug){"
      .AddNL "    TheApp.ReportIncomingArguments(displayname, includeMedia, debug)"
      .AddNL "}"

      WV.AddScriptToExecuteOnDocumentCreated .ToString
  End With
  WV.NavigateToString "Dummy-Document-Content"
  
  WV.jsRunAsync "exportChatAsXML", "TheDisplayName", True, False
End Sub
 
Public Sub ReportIncomingArguments(sDisplayname, bIncludeMedia, bDebug)
  Debug.Print sDisplayname, bIncludeMedia, bDebug
End Sub

The error that I'm getting is not really related to the browser, I guess, but I wanted to ask anyway.

https://drive.google.com/file/d/1WwW...ew?usp=sharing

I am injecting the script using AddScriptToExecuteOnDocumentCreated.

I have successfully done this:

Public Sub ReportIncomingArguments(sDisplayname, bIncludeMedia, bDebug)
Debug.Print sDisplayname, bIncludeMedia, bDebug
End Sub

However, when I try to use my WhatsApp function, I get an error saying

What could I check to find out where it goes wrong?

The JS file was done by somebody else. I don't know where the webpack code came from.
But I know that I successfully used the JS in my old browser.

If anybody can suggest what to try to pinpoint the problem, I would be glad.
Thank you!

Looks like:
- another js-dependency (or js-module) is still missing (not pre-loaded)...
- or your larger js-block runs "too early" (try loading it in WV_DocumentComplete with WV.ExecuteScript instead)
- or the script-code needs to be run from within a script tag with attribute type='module': https://stackoverflow.com/questions/...-module-syntax

Best advice I can give at this point, is to get yourself help from a js-Expert...

I did that, and it turned out that the webpack code was either outdated or malformed in some way.
Olaf, your components help me to pay my living since 20 years :-)

If I have added code using "AddScriptToExecuteOnDocumentCreated", how would I clear that again?

I have not checked, but I am afraid that some parts of the JS may be double as I add several JS files.
And some websites do not need all of these scripts.

That is why I wonder if I should do housekeeping and keep everything clean.

As already mentioned in my last post - an alternative way to add script-modules,
is to do it in the DocumentComplete-Event... via WV.ExecuteScript your-module-source-code.

Within that event you can react conditionally what to load, depending on the current Document-URL.

AddScriptToExecuteOnDocumentCreated is useful for:
- truly generic, never-changing helper-functions - which work and are useful on any site
- or to cover very specific "local" or "single-site" scenarios
...(using the current WV-instance which was placed on a specific Form).

Also keep in mind that, when you e.g. write your own UserControl -
you can have different WV-instances (each of them bound to the internal UserControl.hWnd)...
Such a control could have its own Public URL-Property Let and Get ...
and multiple instances of such a UC could be arranged for e.g. "tabbed Browsing".
You could decide, what dependencies you will load - by looking at the incoming NewURL-Param in the URL-Prop-Let-routine.

Would it have any bad impact if I have 2 instances of the browser?
I am not sure if there is a way to make something like tabs.
I would like to quickly switch from etc. google.com to youtube.com.
I manipulate the DOM and execute scripts on these websites. I am currently stuck because my google.com scripts and youtube.com scripts interfere. I guess I can make that work, but I would anyways like to ask if it woul be good practice to keep these 2 apart by using 2 browser instances.

It is best to create two processes, otherwise if two web pages run in one thread, the speed will become slower

[Schmidt]

It is best to create two processes, otherwise if two web pages run in one thread, the speed will become slower

The chromium-engine (which MS-Edge-WebView2 is using under the covers) -
is already working "multi-process-based" underneath - a short view into the Taskmanager would show you that...

So, the hWnd a Client-Process (the VB6-App) will bind a WV-instance to,
is only the "tip of the iceberg" (a ViewPort-rectangle) - these multiple chromium-processes finally "Blit-to" -
(and in the opposite direction, will only receive KeyBoard- and Mouse-Messages from)...

So, no - there is no performance-penalty (and also no memory-problem) with multiple WV-instances in a given VB-App.

Besides, could you please post only about topics you're really knowledgeable about?
(and if you do, then in "better understandable english").

Currently you come across as a "spamming lunatic", resembling a "badly implemented chat-bot".

Hi Olaf,
you have the method "OpenDevToolsWindow", could you please also add "CloseDevToolsWindow" to the API?

[Schmidt]

Hi Olaf,
you have the method "OpenDevToolsWindow", could you please also add "CloseDevToolsWindow" to the API?

AFAIK, there's currently no built-in method in the official typelib for that...

So you have to go via "normal API" (e.g. using FindWindow - the Window seems always to start with the Caption-prefix "DevTools").

How to use the "SetFuncObj" method?

How to use the "SetFuncObj" method?

It's a method, meant for "RC6-internal-use" (to establish easier communication with the js_side of the WV2 in the initialization-phase) -
and I had to make it a Public-Method instead of Friend, for OLE-marshaling to work...)

Once a WV is initialized, the "official UserApi" to place COM-instances in the js-context (e.g for callback-purposes), is:
WV.AddObject ..., ...

Olaf

[tmighty2]

Is there any way to block this error from occuring until the new version has been released? It is pretty distracting in the dev console window.

Under some circumstances, "WV.DocumentURL" might take around 3 seconds.

If I get it in WV_DocumentComplete like this...

Private Sub WV_DocumentComplete()
       
    g_sCurrentURL = WV.DocumentURL
    g_sCurrentTitle = WV.DocumentTitle

... it is always fast.
However, when I call it at other times, it might take up to 3 seconds. That is why I store it in WV_DocumentComplete.

Thanks!

This morning I woke up wondering if Olaf Schmidt has a Wikipedia entry.

Found cause to following issue, no reply needed.

Hi

I am running into issue with Windows Server 2016 which can't even run the WebView2Demo which results in the following error on launch:

Run-time error '430':

Class does not support Automation or does not support expected interface.


The same version of RC6 controls/dll's on my Windows 10/11 workstations work fine but not on 2016.

Have reinstalled MS Webview2 components and also installed MS Edge Browser to but that didn't help.

Any ideas on what I am missing?

Thanks

Carl

...I am running into issue with Windows Server 2016 which can't even run the WebView2Demo which results in the following error on launch:

Just out of interest, was it a missing "registration" of the RC6.dll on that server-machine?
(or something else)?

I heard that there is a way to read and write MYSQL database without installing the driver, just extract a DLL like SQLITE3.DLL?
Maybe a special ADOx86.DLL,ado x64.dll? Can I read and write to the database without installation?
This way, different operating systems will have the same experience and won't cause all kinds of compatibility issues and errors.
EDGE, for example, has a version 109 that supports older Windows 7, Windows 8, and so on. But he can't have a single DLL for all operating systems.
MINIBLINK.DLL does this (a DLL is only 17m-35M, it's like installing IE11, an old version of Google Chrome, some of which is not supported, but works perfectly with electron,node js), but the latest version is only blink 75. Now Google is in version 113

i want to show webview by vb.net with rc6.dll

In the SHARPDEVELOP developer tool, the reference to RC6.DLL does not show the class
Unable to load type library referencing "RC6". The library is not registered. (Exception from HRESULT:0x8002801D (TYPE_E_LIBNOTREGISTERED)) (MSB3287)
Is your RC6.DLL developed in VC++2010? It took me a lot of time to install the WINDOWS 8.0SDK before I could compile it

HOW TO USE IN VB.NET?LIKE THIS

Next you need to register the DLL. Select the Start menu's Run command and execute the statement:

regsvr32 VB6Project.dll
Next start a Visual Basic .NET project. Select the Project menu's Add Reference command. Click the COM tab and find the DLL or click the Browse button to select it. Now the .NET application can use the DLL's public classes as shown in the following code.

Private Sub btnCallSubroutine_Click(ByVal sender As _
    System.Object, ByVal e As System.EventArgs) Handles _
    btnCallSubroutine.Click
    Dim vb6_class As New VB6Project.MyVB6Class
    vb6_class.VB6SayHi()
End Sub

Private Sub btnCallFunction_Click(ByVal sender As _
    System.Object, ByVal e As System.EventArgs) Handles _
    btnCallFunction.Click
    Dim vb6_class As New VB6Project.MyVB6Class
    MessageBox.Show("Returned: " & vb6_class.VB6ReturnHi())
End Sub

Those last two posts do not appear to be related in any way to the topic at hand. The topic does seem to have wandered a bit, so the second one is kind of on topic, but not the post about SQLLite.
