Off Line Adobe Form has to be Locked

Hi Gurus,

I have a requirement in Off Line Adobe Forms.

We are sending a Adobe Form to user through mail.User is trying to edit some data by using Acrobat Writer. So client is asking to put a restriction/protect/Lock to the Form.So that user can't edit anything.

I don't want to use password Protect method.

I want to use this syntax,but not sure as I don't have Acrobat Writer : form.sf1.access = "protected"; // or use readOnly.

Please suggest me as this is very urgent.

Thank in advance.

Regards,

Bharath
