Use custom cursors if the check box is checked. void ListDragSource_GiveFeedback( Object^ /*sender*/, System::Windows::Forms::GiveFeedbackEventArgs^ e ) See the DoDragDrop method for the complete code example. This code excerpt demonstrates using the GiveFeedbackEventArgs class. If the drag operation moves outside the bounds of the form, then the drag-and-drop operation is canceled in the Quer圜ontinueDrag event handler. The data to drop for the right ListBox is determined in the DragDrop event handler and the String value is added at the appropriate place in the ListBox. Finally, the status of the drop is displayed in the DropLocationLabel Label. If the data to drop is not a String, then the DragEventArgs.Effect is set to DragDropEffects.None.

The location in the ListBox where the drop would occur is also determined during the DragOver event. The keyboard state is evaluated in the DragOver event handler for the right ListBox, to determine what the drag operation will be based upon state of the SHIFT, CTRL, ALT, or CTRL+ALT keys. The custom cursors are set in the GiveFeedback event handler.

The custom cursors will be used if the UseCustomCursorsCheck CheckBox is checked. The example assumes that two cursor files, 3dwarro.cur and 3dwno.cur, exist in the application directory, for the custom drag and no-drop cursors, respectively. The example also demonstrates using custom cursors for the drag-and-drop operation. The IndexFromPoint method is used to determine the index of the item to drag during the MouseDown event. The drag action starts if the mouse has moved more than SystemInformation.DragSize from the mouse location during the MouseDown event. The example calls the DoDragDrop method when the drag action starts. The following example demonstrates a drag-and-drop operation between two ListBox controls. True if the default pointers are used otherwise, false.
