The return value is the complete set of Const.FIELD_* flags.
Applications should use the Const.PM_DataItemFlagGet message to retrieve the complete set of field flags for the data item. To find out if specific flags are set, the Const.PM_DataItemFlagQuery message should be used.
This example retrieves the flags from a data item and tests of the item is any type of key (primary key or parent key).
Set nFlags = SalSendMsg( hWndItem, PM_DataItemFlagGet, 0, 0 ) Set bItemIsKey = nFlags & ( FIELD_Key | FIELD_ParentKey )
This example retrieves the flags from a data item and tests of the item is queryable
nFlags = Sal.SendMsg(cQueryInfo.__hWndQueryInvokerChild[i], Const.PM_DataItemFlagGet, 0, 0);
bItemIsKey = (bool)(nFlags & Const.FIELD_Query);
