Use a Data Object Macro. Data Object macros should be placed in either the System project > System_Macros module or the User project > User_Macros module. The scope of the method added should always be Public, and the method must have a single parameter of type IBBDataObject. An example of how you would implement a Data Object macro (under RE > Tools > Visual Basic  System > Modules > System_Macros) on an Address record is below.

Public Sub AddressMacro(oARecord As IBBDataObject)

     If TypeOf oARecord Is CConstitAddress Then
        'Insert custom code here
        MsgBox "Address Form macro is active"
     Else
        MsgBox "Address Form macro is NOT active"
     End If

End Sub
Note: Macros executed within tabs will not show immediate results and the form does not auto-refresh. It will only show after the form has been saved and closed. This is due to the inherent nature of VB6 which needs to unload and redraw the form in order to display the update.
