Returns information about one or more of the items being dragged.

abstract member GetDropInfo : uint32 * IDataObject * IDropSource -> int

Public Function GetDropInfo (ByRef pdwOKEffects As UInteger, ByRef ppDataObject As IDataObject, ByRef ppDropSource As IDropSource) As Integer

Parameters

pdwOKEffects: UInt32

[out] Pointer to a DWORD value describing the effects displayed while the item is being dragged, such as cursor icons that change during the drag-and-drop operation. For example, if the item is dragged over an invalid target point (such as the item's original location), the cursor icon changes to a circle with a line through it. Similarly, if the item is dragged over a valid target point, the cursor icon changes to a file or folder.

ppDataObject: IDataObject

[out] Pointer to the IDataObject interface on the item being dragged. This data object contains the data being transferred in the drag-and-drop operation. If the drop occurs, then this data object (item) is incorporated into the target hierarchy or hierarchy window.

ppDropSource: IDropSource

[out] Pointer to the IDropSource interface of the item being dragged.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsHierarchyDropDataSource::GetDropInfo(  
   [out]DWORD* pdwOKEffects,  
   [out]IDataObject** ppDataObject,  
   [out]IDropSource** ppDropSource  
);

This method changes the cursor based on the item that the source data is dragged over. The cursor values are determined by OLE. For example, for an effect of DROP_NONE, a circle with a line through it is displayed; for a move, a box with an arrow is displayed; and for a copy, the move icon with a plus sign is displayed.
