CDateTimeCtrl blank field support

Does anyone know how to make a CDateTimeCtrl support a blank value under program control or user input without using the show none
property? We do not want the user to be able to turn the control on or off. Whenever we set the value to blank, when the focus is lost
the control resets the value to the current date. We are using a SetWindowText call to set the value to blank.

Did you get an answer to your problem. I am facing the same problem...
