>I have a container class with an ActiveX control inside. I want to be able to validate user's input and stay in the control if the input is invalid. I thought I can use LostFocus event of my container class and NODEFAULT in the LostFocus would prevent me from leaving this control. However, this is not what happening. The focus still goes to the next control in sequence. What should I do?

It is horrid, but is the only solution without a coordination with container's member.

ELSE
  Container::setFocus
ENDIF
