The best way to get rid of bindweed is to cut it off at soil level. Don't bother pulling it up; it will just sprout wherever you tore the roots, and it is virtually impossible to get all the roots out. Roots can go 20 ft. deep. By continually cutting it off at ground level, and doing it as soon as you possibly can, you will eventually starve the plant (since it will be unable to photosynthesize), and it will die. Be patient! You may have to do this many times, but it will eventually do the trick. Roundup is not very effective as the plant is resistant and also the herbicide cannot affect the huge network of roots.
This URL is a very complete study of this weed. It also highlighted the complexity of the problem. Excluding light completely helps greatly, but the seeds already in the soil tend to persist. Sorry for the bad news.
