If I develop an OCX in VB6 professional, can I use it within VB5 SP3 without any trouble?

I use VB6 (Yes, I have paid for it , I installed it yesterday) at home and VB5 at work.

As for now, I know that it will contain only 2 commandbuttons, 1 shapecontrol, 1 timer.

Is there any difference in the way you write the code for an ocx in VB6 versus VB5?
