Creation of transparent vertex points in Direct3D

See more:

C++

DirectX

In my codes that have been copied under these lines, I first combine two images with using of<i> Alpha Blending Technique</i>, and then 12 points in various sizes are drawn over the combined images. I want to <b>draw these points transparently</b>. How it is possible?
Any help is appreciated.
