public int DragOverArea (uint grfKeyState, uint itemid, uint area, out uint pdwEffect);
abstract member DragOverArea : uint32 * uint32 * uint32 * uint32 -> int
Public Function DragOverArea (grfKeyState As UInteger, itemid As UInteger, area As UInteger, ByRef pdwEffect As UInteger) As Integer

Parameters

grfKeyState
UInt32

[in] Current state of the keyboard keys and the mouse modifier buttons.

itemid
UInt32

[in] Item identifier of the drop data target over which the item is being dragged. For a list of itemid values, see VSConstants.VSITEMID.

On return, the pdwEffect parameter must contain one of the effect flags that indicate the result of the drop operation. For a list of pwdEffects values, see DragEnterArea(IDataObject, UInt32, UInt32, UInt32, UInt32).

Returns

Int32

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