Line3d in Winform

I just can`t make it show line , i`m using ogredotnet in winform does line3d work in it ?

huh fixed , didn`t know i got to do
myLine.drawLines();
every time I do
Root.RenderOneFrame();
RenderWindow.Update();

i'm trying to draw some lines but i cant do it, i have put the drawlines function just where u put it, but it doesnt work either, i cant see anything

here is the code

public void Go()
{
line.drawLines();
mRoot.RenderOneFrame();
mWindow.Update();
}

where in the CreateScene function, i set the line points and attach it to a scenenode, can u tell me why it doesnt work ?? looking forward to hearing from u soon
