[RESOLVED] Reference to a non-shared member requires an object reference

[Meestor_X]

I think you want something like this:
Public myColor As New Color_Class(Me)

Thanks for the fast answer. What's the significance of (Me) in that declaration?

I have to say though, from the example that you've provided I can't see any advantage to defining a nested class over just putting that behaviour in the control itself.

Well, I'm probably mis-guided, but I like the idea of a class that contains many sub-classes.

Like:

Class Machine
  Public Name As String
 
  Class Modes
     Private _currentMode as Byte
     Public Const OFF as Byte = 0
     Public Const ON as Byte = 1
     Public Const Standby as Byte = 2
 
     Property Mode() as byte
         Get
             Mode = _currentMode
         End Get
         Set(ByVal value as byte)
             If value >=0 and value <=2 Then
                 _currentMode = value
             End If
      End Property
 
      Sub ChangeMode()
           Machine.Operate(_currentMode)
      End Sub
  End Class
End Class
.
.
.
Public myMachine as new Machine
myMachine.Name = "Herbert"
myMachine.Mode = myMachine.Modes.ON
myMachine.Mode.ChangeMode

I guess you're suggesting that I don't bother?
