Looking at the horoscope of your daughter she will enter the Venus or Shukar mahadasha on April 2017. As Venus mooltrikona sign is in the 12th house of her horoscope, Venus is a functional malefic planet for her.
One thing that you should remember that no Mahadasha is going to give 1 type of results for the complete period.
Venus Mahadasha is for 20 years, therefore you will not get one type of results for 20 years. The results will depend upon the transit or gochar. Whenever Venus is weak or afflcited in Gochar / Transit you can expect bad results. Whenever Venus would be strong in Gochar you can expect good results.
