Ordinary Controls vs. Activex controls

[sawer]

Thanks for opinion.
Actually "to speak COM to talk to the control" isn't problem for me.

I think the advantage of activex is:

-If the control activex, developer can adjust its property, events using IDE( I mean Properties window). But we can't use this feature for ordinary controls.

Advantages of choosing ordinary controls (I am not sure if these are completely right)

-I heard that ordinary MFC controls are faster than activex.

-Also if someone get your ocx control, he/she can use it without lib and header file. But ordinary controls must be shipped with lib and header file. So control writers can protect illegal use of his control by writing ordinary controls.

If flexibility is important writing Activex controls must be chosen.
and
If performance is important writing ordinary MFC control must be chosen.

Do you agree?

And, i searched for controls, there are so many firms that sell .NET controls but i couldn't see anyone advertise activex controls.(for example http://www.dundas.com/Products/index.aspx ). What is wrong with native(unmanaged) control development? For example why didn't Dundas write and sell MFC Chart controls, why are they only .NET?
