  We discuss the EUV and X-ray properties of B stars, focusing on $\epsilon$
CMa (B2 II) which is the only star with both emission lines and a photospheric
continuum detected with EUVE. We explore the modest effects of the photospheric
EUV continua on the wind, as well as the much stronger effects of the
short-wavelength EUV and soft X-ray emission lines. Attenuation of the EUV and
soft X-ray emission by the wind plays an important role, and leads to the
reprocessing of X-rays via He$^+$ ionization and the Bowen mechanism in the
wind. Finally, we explore some of the new diagnostics that will shortly become
available with the next generation of high spectral resolution X-ray
telescopes. All of this analysis is presented in the context of a two component
stellar wind--a dense component (clumps) that contains most of the mass but
fills a negligible fraction of the volume, and a rarefied component that fills
most of the volume but accounts for only a small fraction of the mass.
