Great! Thanks! Too bad you have to pay to check it out.

But I think I will be able to do pretty much the same, with the help of Christian Ehlscheid instructions in this thread.

BTW I wonder what they use GlobalAlloc, GlobalFree, GlobalSize for?

Anyway, I am thinking its so much trouble to do it this way, having to build a resource only dll with the icons, just to show a custom icon on a messagebox, that I may just do an all foxpro code messagebox replacement class/function, using forms, etc.

(Christian: I found a sample to do a resource only dll easily with VB6)

That way I will be able to customize position (center on app for example, and not on screen), buttons position (center or right), icon, etc etc.

Thank you all for your comments, it has helped me a lot.
