Hello everyone, always thanking you
i can't understand this error

 

[Angelo Messina]

PrefDialog.ShowDialog(Item, "OK", "EXIT")) Complete (Result As Int)

Item as Map
{Edit=5, Tipologia=Appuntamento, Descrizione=andare dal medico, Scadenza=1624485600000, Ora=[IsInitialized=true, Years=0,
Months=0,Days=0,Hours=17,Minutes=25,Seconds=0], Note=Nuovo}

Are you sure the error is in that code fragment? I don't see how it can be. We need more information.

Yes. This is not the correct way to create a Period object.

Correct:

Dim p As Period
p.Initialize
p.Months = 5
Item.Put("Ora", p)
