Private Sub Form_Load()
ActiveDcam1.Acquire=True
HScroll1.Value = ActiveDcam1.Iris
HScroll1.Min = ActiveDcam1.GetIrisMin
HScroll1.Max = ActiveDcam1.GetIrisMax
End Sub

Private Sub HScroll1_Scroll()
ActiveDcam1.Iris = HScroll1.Value
End Sub

This property changes the opening of the lens diaphragm. The valid property range is reported by the GetIrisMin and GetIrisMax methods. Note that the property is available only if the currently selected camera is equipped with a motorized lens and supports software iris control.
