Re: WIN32OLE_RECORD and WIN32OLE_VARIANT

I get a type mismatch


    19: def line_from_pts(pts, el = WIN32OLE_VARIANT::Nothing)
    20:   ole_points = pts.map{ |pt| app.to_ole_point3d(pt) }
    21:   ole = app.ole_obj.CreateLineElement1(el, ole_points)
    22:   if ole
    23:     add_element(ole)
    24:   else
    25:     binding.pry
    26:   end
    27: rescue Exception => e
    28:   binding.pry
 => 29:   return nil
    30: end
[1] pry(#<Microstation::Model>)> e
=> #<WIN32OLERuntimeError: (in OLE method `CreateLineElement1': )
    OLE error code:0 in <Unknown>
      <No Description>
    HRESULT error code:0x80020005
      Type mismatch.>
[2] pry(#<Microstation::Model>)> ole_points
=> [#<WIN32OLE_RECORD(Point3d) {"X"=>0.0, "Y"=>0.0, "Z"=>0.0}>,
 #<WIN32OLE_RECORD(Point3d) {"X"=>0.0, "Y"=>20.0, "Z"=>0.0}>,
 #<WIN32OLE_RECORD(Point3d) {"X"=>20.0, "Y"=>20.0, "Z"=>0.0}>,
 #<WIN32OLE_RECORD(Point3d) {"X"=>0.0, "Y"=>0.0, "Z"=>0.0}>]
[3] pry(#<Microstation::Model>)> el
=> #<WIN32OLE_VARIANT:0x000000000c00e3b0>

I have a similar function for drawing line from to points that works so the
element el of type WIN32OLE_VARIANT::Nothing is the correct type

this function works

   def line(p1,p2,el = WIN32OLE_VARIANT::Nothing)
      pt1 = app.to_ole_point3d(p1)
      pt2 = app.to_ole_point3d(p2)
      begin
        ole = app.ole_obj.CreateLineElement2(el,pt1,pt2)
      rescue Exception => ex
        binding.pry
        return nil
      end
      add_element(ole) if ole
    end

With this function signature from olegen.rb

 # _LineElement CreateLineElement2
  #   _Element arg0 --- Template [IN]
  #   Point3d arg1 --- StartPoint [IN/OUT]
  #   Point3d arg2 --- EndPoint [IN/OUT]
  def CreateLineElement2(arg0, arg1, arg2)
    ret = _invoke(1610743982, [arg0, arg1, arg2], [VT_BYREF|VT_DISPATCH,
VT_BYREF|VT_DISPATCH, VT_BYREF|VT_DISPATCH])
    @lastargs = WIN32OLE::ARGV
    ret
  end
