IAsyncOperation::StartOperation method

Applies to: desktop apps only

Called by a drop target to indicate that asynchronous data extraction is starting.

Syntax

Copy

HRESULT StartOperation(
  [in]  IBindCtx *pbcReserved
);

Parameters

pbcReserved [in]

Type: IBindCtx*

Reserved. Set this value to NULL.

Return value

Type: HRESULT

Returns S_OK if successful or a COM error value otherwise.

Remarks

The drop target calls this method to notify the data object that asynchronous data extraction is starting. The method should store this information so that it can be returned by IAsyncOperation::InOperation. Once StartOperation has been called, the drop target returns the IDropTarget::Drop call as it would for normal synchronous data extraction.
