Get Video Card Shader Model

Hi,
Does anyone know how to get the Shader Model version installed?? Or the Vertex and Pixel Shader Version.
I heard about doing it with GetDeviceCaps, but I can't find anything on how to do it...

If anyone could help, it'll be great!
Best regards,
Jorge

Maybe the Pixel Shader 2.0 example at http://www.flipcode.com/archives/Pix...rsion_20.shtml can be of some help to you.
