BUG (?): DragCopy event ID

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

Here is an interesting one: when handling drag and drop copy (Ctrl + drag) XTP_NC_CALENDAR_BEFORE_EVENT_EDIT_OPERATION::xtpCalendarEO_DragCopy notification, XTP_EVENT_DRAG_OPERATION_PARAMS member pDraggingEventNew contains the same event ID as the original pDraggingEvent. Effectively, there is no way to know what ID the newly created event will contain once the drag operation has been completed.

Anyone else run into this? Any ideas how to solve this one?

Thanks...

Gary

	Hi, The Calendar control uses AddEvent method of data provider. You can catch calendar notification XTP_NC_CALENDAREVENTWASADDED. Also to mark that event is coming from dragCopy operation, you can use event custom properties. I mean inside XTP_NC_CALENDAR_BEFORE_EVENT_EDIT_OPERATION notification handler set a custom property for new event, like: COleVariant varOrigID = (long)pDraggingEventNew->GetEventID(); pDraggingEventNew->GetCustomProperties()->SetProperty("DragCopyEventIDorig", varOrigID); Inside XTP_NC_CALENDAREVENTWASADDED notification handler: CXTPCalendarEvent* pEvent = (CXTPCalendarEvent*)lParam; COleVariant varOrigID; if (pEvent->->GetCustomProperties()->GetProperty("DragCopyEventIDorig", varOrigID)) { // this event added by DragCopy operation. DWORD dwNewID = pEvent->GetEventID(); // as example, remove this custom property and update event pEvent->GetCustomProperties()->RemoveProperty("DragCopyEventIDorig"); VERIFY( pEvent->GetDataProvider()->ChangeEvent(pEvent) ); } -- WBR, Serge
