Hi am trying to make one tutorial of physx in slimdx but i get en error writing the vertexbuffer:
the error message saids: don´t valid operation because of the actual state of the object.
here is my debug message:

and here the function where i create the verxtexbuffer:
Protected Overloads Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
device.Clear(ClearFlags.Target Or ClearFlags.ZBuffer, Color.Black.ToArgb, 1.0F, 0)
Dim debugrenderables As DebugRenderable = gscene.GetDebugRenderable
Dim triangles As DebugTriangle() = debugrenderables.GetDebugTriangles
Dim Points As DebugPoint() = debugrenderables.GetDebugPoints
Dim lines As DebugLine() = debugrenderables.GetDebugLines
Dim Vb As VertexBuffer = New VertexBuffer(device, lines.Length * 2 * 16, Usage.WriteOnly, VertexFormat.Position Or VertexFormat.Diffuse, Pool.Managed)
Dim vertices As MyOwnVertexFormat() = New MyOwnVertexFormat((lines.Length * 2) - 1) {}
For i = 0 To lines.Length - 1
vertices((i * 2)) = New MyOwnVertexFormat(lines(i).Point0, Color.Lime)
vertices((i * 2) + 1) = New MyOwnVertexFormat(lines(i).Point1, Color.Lime)
Next
Dim datStre As DataStream = Vb.Lock(0, 0, LockFlags.None)
datStre.WriteRange(vertices)
Vb.Unlock()
device.BeginScene()
device.SetStreamSource(0, Vb, 0, 16)
device.DrawPrimitives(PrimitiveType.LineList, 0, 30)
device.EndScene()
device.Present()
Me.Invalidate()
End Sub
