Need help creating an ActiveX Dll from a class

I need help creating an ActiveX Dll from the class posted below. Each time I try to compile the Dll, I get the following message error "No creatable public component detected." Also, after you create the DLL, could you create a sample project using the DLL in a standard exe?

Class:

Option Explicit

' The PictureBox we draw on.
Public picCanvas As PictureBox

' The rectangle's drawing attributes.
Public X0 As Single
Public Y0 As Single
Public Radius As Single
Public DrawWidth As Integer
Public ForeColor As OLE_COLOR
Public FillColor As OLE_COLOR
Public FillStyle As FillStyleConstants
Public DrawStyle As DrawStyleConstants

' Default property values.
Private Const m_def_X0 = 0
Private Const m_def_Y0 = 0
Private Const m_def_Radius = 80
Private Const m_def_DrawWidth = 1
Private Const m_def_ForeColor = vbBlack
Private Const m_def_FillColor = vbBlack
Private Const m_def_FillStyle = vbBlack
Private Const m_def_DrawStyle = vbSolid

' Draw on picCanvas.
Public Sub Draw()

   Form1.Picture1.ForeColor = ForeColor
   ' Set other drawing attributes.
   With fmyform(iCurrentProcId).picCanvas
       .FillStyle = FillStyle
       .FillColor = FillColor
       .DrawWidth = DrawWidth
       .DrawStyle = DrawStyle
   End With

   ' Draw the object.
   Form1.Picture1.Circle (X0, Y0), Radius, Form1.Picture1.ForeColor
End Sub

' Set default property values.
Private Sub SetDefaultProperties()
   X0 = m_def_Y0
   Y0 = m_def_X0
   Radius = m_def_Radius
   DrawWidth = m_def_DrawWidth
   ForeColor = m_def_ForeColor
   FillColor = m_def_FillColor
   FillStyle = m_def_FillStyle
   DrawStyle = m_def_DrawStyle
End Sub

' Set some defaults.
Private Sub Class_Initialize()
   SetDefaultProperties
End Sub
