Basic vB4 page code

[raaowdot]

Does anyone know what the basic code is I can use to keep a user logged into a non vb page?

I'm writting a php page which won't use any of the vb templates but I do want to control which users can see which bits of the page.

In vb3 I simply had a bit of code at the begining of my php files which linked in the vb variable such allowing me to reference vb variables such as username, avatar, usergroup etc.

I'm only intermediate with coding but I get the feeling vb4 is a whole new bag of coding and I may no longer be able to do this. But then how to you go about linking in add-on applications otherwise?

Any help will be greatfully apriatiated.
