    Option Explicit
    'Note, that this Demo requires the properly registered RC6-Binaries
    'and in addition an installed "Chromium-Edge" (in its "evergreen" WebView2-incarnation)
    'installable from its official MS-Download-URL:
    Private WithEvents WV As cWebView2 'declare a WebView-variable WithEvents
    Private Sub Form_Load()
      Visible = True '<- it's important, that the hosting TopLevel-Form is visible...
                     '...(and thus the Child-PicBox indirectly as well) - before we Bind the PicBox to the WebView
      Set WV = New_c.WebView2 'create the instance
      If WV.BindTo(picWV.hWnd) = 0 Then MsgBox "couldn't initialize WebView-Binding": Exit Sub
    '  Set WV = New_c.WebView2(picWV.hWnd) 'create the instance
    '  If WV Is Nothing Then MsgBox "couldn't initialize WebView-Binding": Exit Sub
    End Sub
    '*** VB-Command-Button-Handlers
    Private Sub cmdNavigate_Click()
       WV.Navigate "" '<- alternatively WV.jsProp("location.href") = "" would also work
       'the call below, just to show that our initially added js-functions, remain "in place" - even when we re-navigate to something else
       WV.jsRunAsync "test", 2, 3
    End Sub

      If Not WV Is Nothing Then WV.SyncSizeToHostWindow
    End Sub
    Private Sub picWV_GotFocus() 'same thing here... when the hosting picBox got the focus, we tell the WebView about it
      If Not WV Is Nothing Then WV.SetFocus
    End Sub
    '*** the above two EventHandlers (of the hosting VB-PicBox-Container-Ctl) are basically all what's needed "GUI-Binding-wise"
    '*** the rest of the EventHandlers below, are raised by the WebView-instance itself

      Debug.Print "WV_InitComplete"
