I found this code here

Code: Select all  Expand view
auto options = Microsoft::WRL::Make<CoreWebView2EnvironmentOptions>();
    hr = options->put_AdditionalBrowserArguments(L"--allow-file-access-from-files");

    hr = CreateCoreWebView2EnvironmentWithOptions(
        nullptr,
        appData,
        options.Get(),
        Callback<ICoreWebView2CreateCoreWebView2EnvironmentCompletedHandler>(
            this,
            &CEdgeCtrl::OnCreateEnvironmentCompleted).Get());


How to convert it to FWH?

Thanks for the sample Antonio.
I am more on looking for how to display an XML file/content verbatim.

Of course, can use memoedit() for that but that doesn't have syntax highlighting at all

TIA

I'll just use fw_memoedit() for now until I have time to revisit the issue later

Can also use
Code: Select all  Expand view
HtmlView( FullName( cXmlFile ) )

And, there is an exclusive FWH function for viewing XML files.
Code: Select all  Expand view
FW_XmlView( cXmlFile )

You may try this also.

Thanks Rao! This suits my want perfectly.
Any way to view the source of document? Just in case I would like to inspect the raw XML where '<' is actually written as &lt; ?
