In most cases you'll want to use a Datastore object instead. If you absolutely must create a DW reference at runtime you can open an invisible window and get a valid DW like this:

window wdummy
datawindow dw
Open(wdummy)
wdummy.hide()
dw = create datawindow
wdummy.openuserobject( dw )
dw.dataobject = 'd_whatever'
dw.settransobject( ... )
dw.retrieve(...)

// Do stuff

wdummy.closeuserobject( dw )
close( wdummy )

Hi Marco;

   Yes & No...

• No as the DWO is a "custom" object that cannot exist outside a "container" class
• Yes if you have the DWO embedded within a DW Contol or DataStore. then the DC/DS object's pointer can be passed as an object pointer to an event or function.
