I have one main form (parent) which contains others child forms. The first child form is a login form, that after correct autentication opens another child form.

Depending on the user (operator or supervisor) some sub menu (menustrip) in form Parent should be available or not. The supervisor will have full menu available, the user only some sub menu.

How can I disable/enable sub menu in parent from child? anyone can help me?

thx b4
