The fFrame data member of a command represents the display frame that is affected by the change. In the case of a dialog you shouldn't pass the dialog frame to the command unless the command is undoable while the dialog is open. In your case fFrame is apparently not used in your UndoIt and RedoIt methods, so you're getting away with it.
