Rendering lines using 2 pixels width

It is very useful when you want to highlight the lines in one application.
How can we do this in Direct3D ?
By default, all the lines are rendered with 1 pixel width, and setting
the device.RenderState.PointSize don

Some cards dont support variable width line drawing. Id suggest using the Line class under D3DX.

Actually, NO cards support variable width line drawing under D3D. Its just not supported by the API. If it makes you feel better, cards generally dont support it under OpenGL either. The runtime turns the line into a quad and passes it on, which is basically what D3DX.Line does.
