In Microsoft Access from the startup menu we can hide menus ,
Except menu bar.

Is there any way to hide that ?

You can create a Custom menu and only include what you want on it.

From tools ---> customize ---> tollbars tab , again we can't uncheck
Menu bar.
I want to sale my project , but without any menu.

No, you would have to do this in VBA. Lookup Custom menus in VBA Help.

Be sure to convert your app to an MDE before distributing to purchasers.
