WebBrowser not loading phpmyadmin

[Daveeed]

Hey! I'm trying to load on the WebBrowser a phpmyadmin website, but it's loading only half...

I set the IE version of the app to 11, and tried to load the same site on IE and Edge, both do load it correctly, only the WebBrowser doesn't. Any ideas, suggestions?

[dday9]

What happens if you replace the WebBrowser control with the WebView2 control? Does it do the same thing?

[Daveeed]

It does work with WebView2. Can't I solve it without any external libraries?

[dday9]

As far as I am aware, the WebView2 is not an external library.

[Daveeed]

Okay, then I will use it, but now comes another problem. On the PC where I have the VS, the WebView2 loads correctly, everything s fine, but when I come to test it on 2 other devices, the WebView2 is blank white. Any ideas?
*Edit: the Webview2_NavigationCompleted doesn't get called on the other devices.

[dday9]

Can you please provide the relevant code?

[Daveeed]

It doesn't have any relevant code, I just set the source to the Phpmyadmin site, and called an Msgbox to check if the Webview2_NavigationCompleted was called..
The one that is not on default, it's docked to the center screen.

[dday9]

That sounds as if there is code to share. If you are unwilling to share it then I understand, but please understand that I cannot be of much help without it.

[Daveeed]

I'll try to show you anything may related to this.

    Private Sub TabPage2_Enter(sender As Object, e As EventArgs) Handles TabPage2.Enter
        Me.WindowState = FormWindowState.Maximized
        WebView21.Source = New Uri("http://217.144.54.31/phpmyadmin/")
        'WebView21.ExecuteScriptAsync("document.getElementById('input_username').value = '-'")
        'WebView21.ExecuteScriptAsync("document.getElementById('input_password').value ='-'")
        'WebView21.ExecuteScriptAsync("document.getElementById('input_go').click()")
    End Sub
    Private Sub WebView21_NavigationCompleted(sender As Object, e As CoreWebView2NavigationCompletedEventArgs) Handles WebView21.NavigationCompleted
        MsgBox("Completed!")
    End Sub

Hope it helps you, I have no more ideas..

[dday9]

I would first suggest removing the source from the property window in the designer view and then swap this line out with the Navigate method (documentation):

' replace
WebView21.Source = New Uri("http://217.144.54.31/phpmyadmin/")

' with
WebView21.Navigate(New Uri("http://217.144.54.31/phpmyadmin/"))

My second suggestion is to try another event, perhaps the DOMContentLoaded event (documentation):

Private Sub WebView21_DOMContentLoaded(sender As Object, e As CoreWebView2DOMContentLoadedEventArgs) Handles WebView21.DOMContentLoaded
    MessageBox.Show("The initial HTML document has been parsed.")
End Sub

If neither of those two suggestions work, then you could go nuclear and try to bind the event handler using JavaScript if all you are trying to set are some input values:

WebView21.Source = New Uri("http://217.144.54.31/phpmyadmin/")
WebView21.ExecuteScriptAsync("
    window.addEventListener('load', () => {
        document.getElementById('input_username').value = 'root';
        document.getElementById('input_password').value = 'SocialRP95'
        document.getElementById('input_go').click();
    }, false);
")

[Daveeed]

Firstly, I don't have a function like WebView21.Navigate(New Uri("http://217.144.54.31/phpmyadmin/")), only WebView21.NavigateToString()
Secondly, I neither have WebView21.DOMContentLoaded event.. Should this be the problem?

Which version of the WebView are you using? You can verify by going to the solution explorer, expanding References, selecting the WebView library, and then inspecting the properties.

I think thats what you talking about.

[dday9]

I'm sorry, but it is not showing up on my end. Something funky is going on with VBForums and images.

Try uploading the image to an external host and then use [img]www.mytemporaryurl.com/my-image-specific-url[/img]. That's the only way I can get images to work on VBForums now.

There is actually an issue with attachments on the forum at the moment.

If you use the features in the "Quick Reply" area they don't attach properly, but you can add attachments via "Go Advanced" and then "Manage Attachments".

Okay then, https://imgur.com/a/maq2Kox

OK, looking at the documentation a bit more it appears as though those events are not exposed in Microsoft.Web.WebView2.WinForms but they are in Microsoft.Web.WebView2.Core.

What happens if you bind the window's load event using JavaScript and set the values in the event handler?

[Daveeed]

In my first PC it does load the page, but doesn't set the inputs. In the other devices, it doesn't even load the page..

 Private Sub TabPage2_Enter(sender As Object, e As EventArgs) Handles TabPage2.Enter
        Me.WindowState = FormWindowState.Maximized
        WebView21.Source = New Uri("http://217.144.54.31/phpmyadmin/")
        WebView21.ExecuteScriptAsync("
        window.addEventListener('load', () => {
        document.getElementById('input_username').value = '';
        document.getElementById('input_password').value = '-'
        document.getElementById('input_go').click();
        }, false);"
        )
    End Sub

        WebView21.ExecuteScriptAsync("
        window.addEventListener('load', () => {
        document.getElementById('input_username').value = '';
        document.getElementById('input_password').value = '-'
        document.getElementById('input_go').click();
        }, false);"
        )
    End Sub

Not sure why it would set the inputs...
It looks like it is clearing them... not setting them.

        document.getElementById('input_username').value = '';
        document.getElementById('input_password').value = '-'

I've just removed the credentials. But the problem starts that the website is not loading even with that part commented ..

[dday9]

This sounds like a compatibility issue. What OS are the three machines?

[Daveeed]

Every machine has Windows 10. Maybe there are some essential libraries, or dependencies which are needed to run the WebView2 control?

[techgnome]

Can you open it using a browser like chrome, Edge, firefox?

-tg

[Daveeed]

The website? Yeah, sure, I can, with chrome and edge too.

[Daveeed]

Any ideas somebody?
