[Gambas-user] Developing a gambas component using gambas.

[Dani Santos]

Thanks Benoit. I thought that the creation of gambas-based components
was more dynamic.

The component I am developing will reproduce one ActiveX Component that
I used in my VB programmer days to easy the development of the
applications but I'm not sure if it will be useful for other.

I think I will follow programming my app without that component but I
will code all the logic of the component into a class so it will be easy
to create the component if people find it useful.

Regards.
