I did it as you recommended. The new code is as follows but I still got the
same exception. If I take away "using" statement, it runs fine but it has
memory leak.

I also tried not to use "using" statement but add geometry.Dispose() after
done with the geometry. I got the same exception. 

There was not a problem when I used with FDO 3.4.0 in Autocad MAP 3d 2010.

 Using gisGeometry As OSGeo.FDO.Geometry.IGeometry =

            'Cast the geometry to a position
            Dim myPosition As OSGeo.FDO.Geometry.IPoint
            Dim pos As OSGeo.FDO.Geometry.IDirectPosition
            Dim env As OSGeo.FDO.Geometry.IEnvelope
            If TypeOf gisGeometry Is OSGeo.FDO.Geometry.IPoint Then
                myPosition = gisGeometry
                pos = myPosition.Position
                dInsertionPoint(0) = pos.X
                dInsertionPoint(1) = pos.Y
                env = gisGeometry.Envelope
                dInsertionPoint(0) = env.MinX
                dInsertionPoint(1) = env.MinY
            End If

        End Using
