Excel - Lock column to user not VBA

Example:  A user enters data into cell A1. The VBA loads data into cells B1 and C1.

I want to lock/protect columns B and C from user changes but if I lock/protect Columns B and C, the VBA can't load data into columns B and C.

How can I lock/protect columns B and C from user entry/changes while allowing the VBA to insert data into B and C?

Thanks

You can do something like this which will allow VBA to update but not the user.

Sheets(1).Protect Password:="Secret",   UserInterFaceOnly:=True

Thanks for your reply. Where in VBA would this line of code be added?
Martin LissOlder than dirtCommented:
Add this to the sheet's code.

Private Sub Worksheet_Activate()
Protect Password:="Secret", UserInterFaceOnly:=True
End Sub
