I protected my VBA code with a password by selecting
Tools- VBAProject - Protection "tab". Then selected
"Lock project for viewing" and I entered a password and
a confirm password. Now when I try view my code the
message "Project is unviewable" comes up. How can I get it
to prompt me for the password to unlock it?
