is it possible change of status from tourist visa to h1b ?,

i mean ive search few related pages but no clue, if you guys have anything about above please reply in brief or

have any information please share.

As far i knew, In case of such change of status you need to move out of the country to get your H1B stamped and with valid stamping only its advisable to enter into US.
