IAsyncOperation::StartOperation method
Called by a drop target to indicate that asynchronous data extraction is starting.
Syntax
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.
