Private Sub objOutlook_OptionsPagesAdd(ByVal Pages As Outlook.PropertyPages)
On Error GoTo PROC_ERROR
    dim objPropertyPage as Object

    set objPropertyPage = CreateObject("SSWContactorPP.ucSSWContactorPP")

    ' this is the magic line
    Pages.Add objPropertyPage

    ' here we pass the DLL as a reference to the property page, so that the property page can
    ' call methods of the DLL.  SetContactor here is an example set property
    Call objPropertyPage.SetContactor(Me)

PROC_EXIT:
    Set objPropertyPage = Nothing
    Set Pages = Nothing
    Exit Sub

PROC_ERROR:
    call msgbox(Err.Description)
    Resume PROC_EXIT
    Resume
End Sub



'In your PropertyPage User Control:
'
'Apart from the required methods, also define a property "caption"

Public Property Get Caption() As Variant
    Caption = "SSW Contactor"
End Property


'Once you've added the Caption property procedure, select the Proedure Attributs option from the Tools menu,
'select the property we just created from the drop-down list (Caption).  Click the Advanced button, and select the 
'Caption procedure ID in the Procedure ID diaglog box.

'Thus, we associate our property (Caption) with the identifier for the caption property on a control, Outlook uses
'this property for the title of the property page when you look at property page in Outlook.
