if i understand what you are trying to do correctly then this should work:

when you press the minimise button the code for the imagebox should be something like this (makes it halfsize)

VB Code:
  1. ImageBox.Height = ImageBox.Height/2

  2. ImageBox.Width = ImageBox.Width/2

and then to maximise it again

VB Code:
  1. ImageBox.Height = ImageBox.Height*2

  2. ImageBox.Width = ImageBox.Width*2

ive never used a circle so im not sure how they work but they would either have a radius, or a X1-X2, Y1-Y2.

If they have a radius control, ie circle.radius then you need to do the same as above:

VB Code:
  1. Circle.Radius = Circle.Radius/2

if it uses the X1-X2, Y1-Y2 method, i would think you need something like this:

VB Code:
  1. Circle.X2 = (Circle.X1 + Circle.X2) / 2

  2. Circle.Y2 = (Circle.Y1 + Circle.Y2) / 2

this will keep the top left corner in the same place and shrink the rest to halfsize

my explanations tend to be longwinded but hopefully you get the idea.
