wpf over activeX

Question

I am trying to overlay buttons on a WindowsFormsHost that contains an activeX control embedding VLC. The issue I have is that activeX is always on top of wpf. Are there any ways to get a wpf control over the activeX control?

The VLC control also does not seem to support rendering to a bitmap.

I finally found a solution. The popup primitive is also an element that is always on top and can be placed over the vlc control. Its a bit of a hack, but it gets the overlay that I needed. My xaml for the player looks like this

<grid>
    <WindowsFormsHost x:Name="Host"
                      Height="200"
                      Width="200" />
    <Border x:Name="Anchor"
            Height="0"
            Width="0"
            HorizontalAlignment="Left"
            VerticalAlignment="Top" />
    <Popup Width="{Binding ElementName=Host,Path=Width}"
           Height="{Binding ElementName=Host,Path=Height}"
           PlacementTarget="{Binding ElementName=Anchor}"
           AllowsTransparency="True"
           IsOpen="True">
        <Border Background="#30808080"
                Width="{Binding ElementName=Host,Path=Width}"
                Height="{Binding ElementName=Host,Path=Height}">
            <Button Content="Start"
                    Height="20"
                    Width="60"
                    Click="button1_Click"/>
        </Border>

    </Popup>
</grid>

The above puts a light grey transparent layer over the vlc player that contains a button. The above doesn't account for if the window is resized or moved, but the issue of putting something wpf over the control has been solved.
