Answer 1

Old question, but here's my go-to for this operation.

If browser.Document IsNot Nothing Then
    browser.Document.OpenNew(True)
    browser.Document.Write(My.Resources.htmlTemplate)
Else
    browser.DocumentText = My.Resources.htmlTemplate
End If

And be sure that any browser.Navigating event DOES NOT cancel "about:blank" URLs. Example event below for full control of WebBrowser navigating.

Private Sub browser_Navigating(sender As Object, e As WebBrowserNavigatingEventArgs) Handles browser.Navigating

    Try
        Me.Cursor = Cursors.WaitCursor

        Select Case e.Url.Scheme

            Case Constants.App_Url_Scheme

                Dim query As Specialized.NameValueCollection = System.Web.HttpUtility.ParseQueryString(e.Url.Query)

                Select Case e.Url.Host

                    Case Constants.Navigation.URLs.ToggleExpander.Host

                        Dim nodeID As String = query.Item(Constants.Navigation.URLs.ToggleExpander.Parameters.NodeID)

                        :
                        :
                        
                        :
                        :

                End Select

            Case Else
                e.Cancel = (e.Url.ToString() <> "about:blank")

        End Select

    Catch ex As Exception
        ExceptionBox.Show(ex, "Operation failed.")
    Finally
        Me.Cursor = Cursors.Default
    End Try

End Sub
