Protecting a VBA project

Hello Gurus,
I have written a macro in Excel.I want to protect this code.Is there any way I can do this?When I give my project to the user,he should only be able to access the worksheet and not be able to see the code at all.Please help.

Thanks & Regards.

Doesn't anyone have any idea at all?Please help or please suggest some other site where I might be able to find help.

in the Visual Basic editor select Tools, VBA Project Properties..., then the Protection tab.

Thanks a lot Cubbie.
