I use WPF to call the C++ encapsulated ocx control to display on the interface, but the WPF native control cannot be displayed on the ocx component. Here is my code to display the ocx control:
<WindowsFormsHost Name="host"  Width="640" Height="470" Margin="0,0,0,0" 
                  VerticalAlignment="Top" HorizontalAlignment="Center">
    <ocx:AxWipFaceOCX x:Name="axWipFaceOCX1"></ocx:AxWipFaceOCX>
</WindowsFormsHost>
