"RICHEDIT_CLASS" is the name of the control's window class and nothing
else. But the control does _not_ consist only of a window, it also has a
window message processing procedure AKA window procedure which offers
default message processing and provides the base functionality. The control
even offers a very extended  functionality to be accessed by the controls
interface which is windows message processing.

This is not base but extended functionality i.e. both for the Windows API
control and the COM control you somehow have to invoke it:

  COM:  X = RTFControl.SelStart
  API:  SendMessage(hWndRTFControl, EM_GETSEL, ...)

The only difference is the interface used, COM vs. windows message
processing. The value returned by SelStart is not provided by the COM
control but by the Rich Edit Control.
Rich Edit Control is a control which can be controlled by the Windows
message processing interface, and the RTFBox is a COM control which wraps
the Windows API Rich Edit Control and can be controlled by COM interfaces.
