Good morning!
Is it possible to create a datawindow at runtime and pass it as a parameter to another function or event?

Thanks!

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.

HTH

Regards .. Chris

DataStore lo_ds

lo_ds = Create DataStore .// Instantiate DS

lo_ds.data object = "dw_object" // Load DW object

// What ever processing ...

<Object>.<UserEvent> ( lo_ds ) // Pass DS + DWO to another object's event

The Datastore object has a Create method that allows you to have a Datawindow object built from a string.

Build the DW syntax string in one window, pass the string to the other window and then create it into a local datastore.
