Collision Help, multiple Class' with inheritance

[RussLee33]

for the life of me i just cant seem to be working out what i am doing wrong, i have managed to make a player and make it shoot. also managed to make enemy spawn in at random locations/speeds in the picture box.

i just cant seem to get any Collision to work, i am trying to keep all enemies in the picture box and bounce back and also bounce off each other, and then destroy them when shot.

i have been trying to use "Ball.Bounds.IntersectsWith(pictureBox2.Bounds)" but it seems that Ball.bounds is wrong.
