i downlaod new current version: 6.0.15, last updated: 2023-07-23
but i found can not run WV.jsProp. i change to 6.0.0.9 work ok.
the other question
the same code if i chang RC6.dl 6.0.0.9 to 6.0.15 ，MsgBox "Couldn't load regfree, will try with a registered version next..."Code:If Right$(App.Path, 1) <> "\" Then AppPath = AppPath & "\"
If App.LogMode Then '
On Error Resume Next
LoadLibraryW StrPtr(AppPath & DirectComDllRelPath)
Set New_c = GetInstanceEx(StrPtr(AppPath & RCDllRelPath), StrPtr("cConstructor"))
'Set New_c = GetInstanceEx(StrPtr(AppPath & "Bin\RC6.dll"), StrPtr("cConstructor"), True) '
If New_c Is Nothing Then MsgBox "Couldn't load regfree, will try with a registered version next..."
On Error GoTo 0
Else '
Set New_c = New cConstructor
End If

Another issue is that playing online videos often results in buffering. And the same browser plays smoothly。How to solve it？thanks

i test your demo WebView2Demo.zip
i found not change red.but old vision work fineCode:and this shows, that the WV.jsProp("...") also works in Property-Let-Mode (at the left-hand-side)
btn1Caption = "Click Me..." 'change the Caption-String
WV.jsProp("document.getElementById('btn1').innerHTML") = btn1Caption 'and assign it to the Browser-Element as the new Caption via WV.jsProp() = ...
'just for fun, we can change the style of the btn1-Element to color='red' as well this way
WV.jsProp("document.getElementById('btn1').style.color") = "red"
This problem came up already a few times here (first time, I think - in #185):Quote:

thanks. jsprop This function is very convenient to use。now must change my code
This was 3 steps back, the problem with the dpi has been solved, but jsProp no longer works as before, everything changed, I still don't know how to fix it. before this worked for me WV.jsProp("map.getCenter().lat()") now not anymore!
Point #185 is not a solution, with WV.jsProp I could access a variable, if it worked fine, why did I change it?
Not "everything" - only jsProp shows a slightly different behaviour...Quote:

(because newer Chromium-versions are now blocking eval() when used against some DOM-props).
So, my workaround around this chromium-issue with eval() was, to now parse a "given property-string" by hand (step by step) -
But note, that this workaround now only works on real property-sequences (and not "props with intermingled function-calls")...
So the string still can be nested with "dots" in-between properties - but no parentheses (no func-calls) are allowed in the string.
WV.jsProp("window.document.title") 'access on "pure" nested props still works
WV.jsProp("map.getCenter().lat()") '...whilst this doesn't anymore, because it contains ()-identifyable, intermingled function-calls
It's not that difficult, to write your own little helper-functions for communication with VB6,Quote:

.AddNL " var c = map.getCenter()"
.AddNL " return [c.lat(), c.lon()].join(';')" 'returns two values (lat and lon) in a semicolon-separated string
.AddNL "}"
WV.AddScriptToExecuteOnDocumentCreated .ToString
End With
Again, normally I try my very best, to not break existing functionality -Code:Debug.Print WV.jsRun("getMapCenter")
but in this case it was the "increased security" of the chromium-engine which "broke things" (on some sites).
Edit: What you can try, to simulate the "old behaviour" is, to run the javascript eval-function explicitely on your own like this:
... Debug.Print WV.jsRun("eval", "map.getCenter().lat()")
...meaning, that you could do a global replace of the term [ WV.jsProp( ] against [ WV.jsRun("eval", ]
This might work on some sites (which don't enforce a "restricted eval()", like the sites delivered from from google-servers for example).
Olaf
Thank you very much, this fixes it
Private Function WV_Eval(ByVal Value As String) As String
WV_Eval = WV.jsRun("eval", Value)
End Function
then replace all WV.jsProp by WV_Eval
jsProp，This function has a lot of problems and bugs,
Your reply doesn't mean anything other than misleading others, and it's not what this forum needs.Quote:

Based on my more than 10 years of experience with RC5/RC6, Olaf's code has very few bugs, and the quality of his code is at the top level even according to the standards of Commercial software.
more times,jsProp("document.title"),result is empty,and other js
WV_Eval replace to WV.jsProp maybe ok
execute WV.ExecuteScript "document.querySelector('#app > div > section > aside > span').click();" sometimes the webpage is not executed successfully. So I will modify it to
WV.ExecuteScript "document.querySelector('#app > div > section > aside > span').click();"
sleep 1000
WV.ExecuteScript "document.querySelector('#app > div > section > aside > span').click();"
sleep 1000
WV.ExecuteScript "document.querySelector('#app > div > section > aside > span').click();"
wo can tell me why？ and hao can do well？
WV.ExecuteScript is working asynchronously.Quote:

it could very well be, that the span-element you want to click - simply "is not there yet".
Please wrap the Selector-query in a small function, which is able to test for "existence" (of a certain, element-addressing query-string).
E.g. you can add the 2 functions below via:
WV.AddScriptToExecuteOnDocumentCreated _
"function elementExists(sQuery){return document.querySelector(sQuery) ? true:false}" & vbCrLf & _
"function clickElement(sQuery){document.querySelector(sQuery).click()}"
And then test for existence via:
Const sQuery As String = "#app > div > section > aside > span"
If WV.jsRun("elementExists", sQuery) Then WV.jsRun("clickElement", sQuery) Else Debug.Print "Element doesn't exist yet..."

There is no built-in method to store the entire contexts (html and images) of a webpage locally, is there?
I thought that since the data is already on my disk when I ask WebView2 to navigate to a certain page, I could perhaps extract the local data.

Hello, I'm struggling to find the way to download a JSon file from an URL as string.
I need to download it using the WebView2 because I'm already using it to log-in to the site and to download some pages, and I need to send the session Cookie to be able to download the JSon, so since I was not able to get the Cookie with the method suggested here (because it appears that is no working now anymore, at least for me), I will have to get the JSon using the WebView2 itself and not by other download means.
I tried to get it with WV.jsProp("document.body.outerText") and it kinda worked but if the JSon is too large it gets cut.
Ideas?

In other words - don't use the Webviews "Navigate"-methods to retrieve JSON from a certain WebAPI -
use the XHR-Object instead "from the inside" of a loaded document (e.g. encapsulated in a little pre-added js-function).
Just tested this here - and it seems to work as described:Quote:

(the WV.AddObject-stuff ... which I need also on the inside of cWebView2, to interact with the VB-side).
E.g. when you navigate to "https:/google.com" - then WV.jsProp and WV.jsRun won't work properly.
Olaf
Hello Olaf. It is not Google, it is a private site.
Debug.Print WV.jsProp("document.cookie") returns an empty string.
Maybe that it is because it is an http site (not https)?
No, the reason in that case is, that document.cookie only returns "regular, non-HttpOnly-cookies"Quote:

You can read about the different cookie-types here, for example:
https://dev.to/costamatheus97/battle...http-only-1n0a
As for: "How to get to those http-only-cookies without using javascript..." -
the WebView2 thankfully raises an Event we can use, where received resource-responses are reported
(including a param, which transports a http-response-headers JSON-collection)...
I've marked that Event in the following demo-code blue:
Edit: One can also use the somwhat more modern "Fetch-API" instead of the XMLHttpRequest-Object:Code:Private WithEvents WV As cWebView2
Private Sub Form_Load()
Set WV = New_c.WebView2(hWnd, 0)

Private Sub WV_InitComplete()
WV.Navigate "http://SomeDomain.com", 0

If RespHeaders.Exists("Set-Cookie") Then Debug.Print RespHeaders("Set-Cookie")
' Dim i As Long 'alternatively, one can enumerate all response-headers on the JSON-Collection
' For i = 0 To RespHeaders.Count - 1
' Debug.Print RespHeaders.KeyByIndex(i), RespHeaders.ItemByIndex(i)
' Next
End Sub
Private Sub Form_Resize()
If Not WV Is Nothing Then WV.SyncSizeToHostWindow
End Sub
https://developer.mozilla.org/en-US/...PI/Using_Fetch
The http-cookie should be transported back to the server automatically in these "internal requests" -
whereas "special tokens" have to be set manually in the clientside Headers of the request (in both cases)...
But just test it out in your own small js-functions (added in WV_Initcomplete via AddScriptToExecuteOnDocumentCreated)
HTH
Olaf
At the end I did it with a WinHttpRequest object that I already know how to handle and it worked.
Thanks a lot!
Hi Olaf,
Many thanks for developing this.
The current WebResourceResponseReceived event only provides
ReqURI, ReqMethod, RespStatus, RespReasonPhrase, RespHeaders
Could you please implement a way of retrieving the response body (and, preferably, request headers & request body as well)?
Attachment 189031
On a customer's computer I see this message when he / I click the microphone button in web.whatsapp.com.
However, when he / I click on it, the result is not saved.
It's not possible to record audio.
Also,
Private Sub WV_PermissionRequested
is not fired.
What could I be missing?
The problem does not occur on my or (so far) any other customer computer.
Olaf, could you offer a service that assures us "companies" to get support and a maintained product or the source code so that we could continue support it ourselves in case something happens to you?
WebView2 is not a product by Olaf, he just delivers a more easy programming interface using his vbRichClient 6 environment.
https://github.com/MicrosoftEdge/WebView2Browser
https://learn.microsoft.com/en-us/mi...edge/webview2/
That is exactely what I am talking about.
Outside this forum and a few other die-hard hobbyists it's pretty hard to still find a demand for VB6 apps, maybe that's why Olaf isn't selling his RC6 components.
Looking at Arnoutdv's links I can see that this WebView2 stuff is pretty massive, so even if Olaf shared the source code I think most users would find it rather complicated to fix things themselves but at least it would open the gates for other experts to chime in and help out.
I am wondering whether Olaf implemented WebView2 in VB6 or maybe it's all C++ in the RC6 DLL?
The problem also does not occur on my machine.Quote:

The OS allows, to define such permissions "App-specific" (for all installed "Store-Apps") -
but also for either "all Desktop-Apps generally", or for "specific Process-Names of Desktop-Apps".
(in a kind of WhiteList - probably stored in the registry somewhere).
Remember, that your own "WebView2-using App" (your Executable) does not run under the flag of "MS-Edge" or something.
(somehow inheriting the permissions of the MS-Browser-Executable)...
No, it is an Executable in its own right (which by default is probably not in the "known list of white-listed Apps").
So, try to find a way, to enable Microphone-usage at that outer level first for your App
(e.g. in a Screen-Session, together with your one problem-customer).
Some systems are quite "closed-off" due to over-eager Company-Domain-Admins -
but that's not a problem the RC6-WebView2-Wrapper can solve...

All wrapper-classes the RC6.dll exposes, are VB6-implemented, since it's a normal VB6-AX-Dll-Project.Quote:

Can this object be made public? It is convenient for people in need to do more operations.
Hi Olaf,
can you release the source code of your components so that we can find a way to go on in case something happens to you?
I'd say - let's talk about that, after "something happened to me"... ;)Quote:

If you are that concerned, that a closed-source-component will not work anymore "next week" (as it was, at the last compile-date),
then simply "choose another component" (as e.g. the .NET-wrapper for WebView2) -
it really is that easy - and up to you to decide.
I've mentioned the "conditions" for opening the RC6-sources already several times here in this forum...
(the main-condition being: "a base for long-term-survival" - aka an OpenSourced, platform-independent compiler, which we do not have currently).
Olaf
Olaf,
there is currently no replacement for VB6 for some developers.
I am not releasing any .NET applications to the public because it means giving away your source code.
I know 2 others who run big businesses using VB6 for the same reasons.
I did convert my apps to .NET and decided against releasing them.
People depend on my business.
My softwares are certified and auditioned regularly as they are used in a medical branch.
If you really mean it (regarding "after I am gone"), then can you implement a system that would make the source code accessible to me (and possibly others whose business depend on it)?
I hope, you notice the irony here...? ;)Quote:

After net was abandoned by Microsoft, the number of VB programmers has been decreasing.
In the past 10 years or so, we have probably contributed the most technology and the most powerful technology.
@Schmidt You have contributed a lot of VB6 technology. Rc6, DLL. Is undoubtedly a very great product, if many people can learn to use it. It's really convenient, and it can also add a lot of functions to your software. A lot of development costs are reduced.
It was supposed to be a paid software product for you to use for free, and we are very grateful to you.
I was recently working on a mini version of the MySQL server, which was compressed to just over 2.8 megabytes.For the full version, it will be more than 50 megabytes normally.
Mysqld. Exe, just start the process.
And then set the super initial password. I studied it for two whole days. In fact, the cost is also very high. It can be interpreted as $500.
There is one from 2003 or so. LIBMysql. DLL, less than 1000kb, it can connect to the MySQL server.It's been 20 years and it's still working. It's incredible.
It's a little off topic.It's just that the research cost of some technologies is actually very high.You can choose open source or partial open source. It's all free.
Many small functions are implemented with difficult technology and patented technology.
We should respect the technology of original developers and give more encouragement.

Hello Olaf,
I am working on a medical management software in France. For security reasons, reading social security cards and physician identification cards from a browser will soon no longer be possible through scripts within the web page, but through approved extensions added to the browser. Until now, I have been using cWebView2 to authenticate myself with these cards, but this will probably no longer be possible in the future.
Apparently, WebView2 can now handle extensions.
Is there a planned update of RC6 that will bring extension management to cWebView2? (Properties AreBrowserExtensionsEnabled, etc…)
Please keep me informed.
Best regards.
François
Ah well, ...finally.Quote:

Thank you for your response, Olaf.
I must admit that I am not familiar with the AddObject functionality!
I will try to find examples in the posts of this thread while waiting for integration into cWebView2.
Unless you have a small example?

However, I don’t see how to switch a WebView2 property inside cWebView2, like AreBrowserExtensionsEnabled to True, through this method.

The example in my prior post was just a suggestion... showing an alternative way how to tackle basically the same thing -
(breaking out of the Browser, calling functionality of the underlying OS via VB and system-APIs) -
entirely "on your own", in a language you know well, without waiting for "plugins" to circumvent "browser-limitations".
Olaf
I understand better Olaf, Thank you.
In fact, in my case, I am required to use the extensions approved by the administration to validate the reading of social security cards and physician identification in the browser context. It is also the back-end of the French national shared medical records management application that addresses the extension to authenticate patients and physicians before delivering health information.
I will wait for the update of the RC6.

I have tried clicking on the last element found within it (next page).
but I don't have an answer to it, what am I doing wrong?
example 1
Code:Dim script As String
script = "var paginationItems = document.querySelectorAll('.mt-ListPagination .sui-MoleculePagination-item');" & vbCrLf & _
"var ultimoItem = paginationItems[paginationItems.length - 1];" & vbCrLf & _
"if (ultimoItem) {" & vbCrLf & _
" ultimoItem.click();" & vbCrLf & _
"}"
WV.ExecuteScript script
example 2
Code:Dim script As String
script = "var ultimoItem = document.querySelector('.mt-ListPagination .sui-MoleculePagination-item:last-child');" & vbCrLf & _
"if (ultimoItem) {" & vbCrLf & _
" ultimoItem.click();" & vbCrLf & _
"}"
WV.ExecuteScript script
example 3
Code:Dim script As String
script = "var ultimoItem = document.querySelector('.mt-ListPagination .sui-MoleculePagination-item:last-child');" & vbCrLf & _
"if (ultimoItem) {" & vbCrLf & _
" var eventoClick = document.createEvent('MouseEvents');" & vbCrLf & _
" eventoClick.initEvent('click', true, true);" & vbCrLf & _
" ultimoItem.dispatchEvent(eventoClick);" & vbCrLf & _
"}"
WV.ExecuteScript script
example 4
Code:Dim script As String
script = "var ultimoItem = document.querySelector('.mt-ListPagination .sui-MoleculePagination-item:last-child');" & vbCrLf & _
"if (ultimoItem) {" & vbCrLf & _
" ultimoItem.scrollIntoView();" & vbCrLf & _
" setTimeout(function() {" & vbCrLf & _
" var eventoClick = document.createEvent('MouseEvents');" & vbCrLf & _
" eventoClick.initEvent('click', true, true);" & vbCrLf & _
" ultimoItem.dispatchEvent(eventoClick);" & vbCrLf & _
" }, 500);" & vbCrLf & _
"}"

Hello Olaf,
In the BindTo function, entering a command in additionalBrowserArguments (for example, "--lang=de") prevents the initialization of WebView2 with version 6.0.15 of RC6.
What am I doing wrong?
Thank you for your assistance.
Kind regards.
François
Just tested this here (on Win11) - and it works as it should...Quote:

IIRC, there was a problem sometime ago, where it was shown -
that *every* "follow-up" WV2-instance in a given Process -
needs to be started with the same commandline-params as the first created one...
I consider that a problem MS has to fix (if it's still there).
Olaf
Thank you Olaf,Quote:

Thanks again for your quick response.
Best regards,
François
Ah, yes - that was the behaviour (which was discussed a few dozen entries back, here in this thread)...Quote:

Olaf
Thanks Olaf, I'll try that right awayQuote:

Thank you for your response.
