Connexion application VB et bd MYSQL en client/serveur 2/3

bonjour chers internautes, je viens par la presente publication vous soumettre mon inquietude et aussi solliciter votre aide.
au fait je suis debutant en programmation et j'ai developpé une petite application qui me permet de faire un enregistrement. j'ai un serieux probleme a faire connecter mon application et ma bd. j'ai mis l'adresse ip du serveur ou ma base est située et a l'aide de ODBC connector j'ai pu faire le referencement mais lorsque je valide un enregistrement on m'affiche ce message:

''echec Unable to connect to any specified MySQL host.''
aidez moi svp!!!
