CCknFlashingDialog cancel

Hi all,
Is there any way for cancelling the CCknFlashingDialog programatically. The dialog will get cancelled automatically upon a key press or if the time is expired.
CCknFlashingDialog::RunDlgLD(*header,*msg,NULL,CCknFlashingDialog::ENormal);

But is there any api by which i can cancel an already displayed CCknFlashingDialog, similar to InfoMsgCancel.

Thanks for the time
