I worked that out in the second forum

VB Code:
  1. Private Sub Frame1_DblClick()
  2. Frame1.Height = Frame1.Height * 2
  3. Frame1.Width = Frame1.Width * 2 'Doubles the frame each time
  4. End Sub

or

VB Code:
  1. Private Sub Frame1_DblClick()
  2. Frame1.Height = Frame1.Height + 2
  3. Frame1.Width = Frame1.Width + 2 'adds 20 to the frame each time
  4. End Sub
