You'll have to edit the core of CB to achieve this or create a Joomla plugin to redirect from CB to VM. Sorry, CB does not support any other login or registration other then its own.

I need this kind of support because each minute i lose money.

my site is off line because there is not an option for registration mode.
I'm asking how i can use the virtuemart registration as main registration.

CB registration create problem at my site.
CB component its OPTIONAL!!!

So, can anybody explain how can i do?

I am trying to understand the real issue here.

CBSubs needs CB Component.
CB component has a cb registration form.

You cannot use the VM registration form instead of the CB one.

Why can't you just use the CB registration form?
All CBsubs plans integrate with it.

CB registration create problem at my site.

What is the problem? It's generally better to resolve the issue then create a workaround. Please provide details of the issue if one is present.

CB component its OPTIONAL!!!

CB is not optional if you have CBSubs; if using CB you need to use CB Login and CB Registration, no exception. Your users will go out of sync and will need to be manually synced everyday and depending on traffic could be every minute.

I explained this already. You need a Joomla plugin to redirect away from CB login and registration pages to VM login and registration pages. This is something YOU need to develop. Please see existing Joomla plugins for example (your plugin will need to be a system plugin).

However, there are many CB to VM integrations available which synchronize users from CB to VM. This would allow usage of CB login and registration, but still maintaining VM integrity as users will be also added to VM properly.
