i cant find any tutorial for vb to xampp database . it always mysql .

@BIM, that's why you read the finds with MariaDB. Such as

Connecting to a Mariadb database with visual basic express 2010

If there is indeed no tutorials (which we know isn't true) then you get on the MariaDB Forum and create that tutorial.

HOWEVER:

MariaDB is a community-developed fork of the MySQL relational database management system

So MySQL tutorials apply.
