function DropArea(
    pDataObject : IDataObject, 
    grfKeyState : uint, 
    itemid : uint, 
    area : uint, 
    pdwEffect : uint
) : int

Parameters

• pDataObject
  Type: Microsoft.VisualStudio.OLE.Interop.IDataObject

  [in] 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.

• grfKeyState
  Type: UInt32

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

• itemid
  Type: 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.

• area
  Type: UInt32

  [in] The area over which the item is to be dropped.

• pdwEffect
  Type: UInt32%

  [in, out] Visual effects associated with the drag-and drop-operation, such as a cursor, bitmap, and so on. The value of dwEffects passed to the source object through the OnDropNotify method is the value of pdwEffects returned by this method.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

Valid values for grfKeyState are shown in the following table. These values can be combined using a bitwise OR operator.
