Thanks For Help

What are you trying to do?

Yes. I got that.

What is it that you want to go faster??
Do you want something to move?
Do you want to add pictureboxes faster?

I Change The Location Of Each Control
When It HAve More Control It Will Be Slower
It Move Each Control Not All In one Step
I Want To Move in One Step Not Move Each Control
I See How About Multithread

Yes. Well.
Having 100 pictureboxes on the form and moving them at the same time in a timer event, will slow things down.
Based on the name of your class BulletArray I'm gonna assume that the pictureboxes contain a picture of a bullet, and that moving the picturebox somehow will simulate that the bullet is moving.

You should instead look into using GDI, and use the Paint method for a panel to move your bullet.
This is just a sample of what can be done, practically flicker free.
The sample is based on this article.
