) : int
Parameters
- pdwOKEffects
Type: System.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
Type: Microsoft.VisualStudio.OLE.Interop.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
Type: Microsoft.VisualStudio.Shell.Interop.IDropSource%
[out] Pointer to the IDropSource interface of the item being dragged.
Return Value
Type: System.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.
