How do I lock a form in Adobe Acrobat Pro9?

Thanks netcmh.  That would be to complicated.  I just want to simply lock the whole form so they can only save a copy.  Any other ideas?

You can add a script to the document "WillSave" event.  In the script set all the fields to ReadOnly.

Use something like this.

this.getField("Myfield").readonly = true;

Or, Go to the menu option Document->Security->Secure This Document, select Restrict Opening and Editing Using Password. Under the "Permissions" section in the dialog that appears, check the box titled "Restrict editing and printing of the document.  A password will be required to change these permissions settings." Make sure to select what options you want available in the Printing Allowed and Changes Allowed pulldowns, choose a password and click OK.  Follow the rest of the instructions given in the following dialogs.  NOTE: One of the dialogs you will see explains that not all third party PDF viewers will respect this password security, so this is not a fool proof security system.

I tried the option to secure it but it still lets me save the changes to the original form.  One of  the options is to allow filling in form fields.  If I set that to allow, they can enter form data and save it.  If I set it to not allowed, they cannot enter form data at all.  Seems like there is no option to allow to fill in form data but not save it.

Yes, there is, and that was my first response. Your clients should be able to fill it in, and once they're satisfied, they'd have to hit submit which would lock it up :)

What if I do not want to use a submit button?  I simply want them to save the filled out form to a network share?  I have seen this before where I open a PDF say from a bank.  At the top it will say "you cannot save data typed into this form"
It then allows me to fill in the form but I cannot save the original.  It will only allow me to save a copy or print.  That is what I want, without anytype of submit button.

While I discuss this with my colleagues, Why can't you just lock the form and hide the submit button (after it's completed) and send that out?

To enable your forms to be filled out, open the form in Adobe Acrobat Pro. Select "Enable Usage Rights in Adobe Reader" from the "Advanced" menu.

You may find that there are still problems, such as, if the user duplicates the form or uses the "save AS" function, they may find their rights disappear.

To allow those using Adobe Reader to save a filled-in form, in Acrobat Pro 9, choose Advanced > Extend Features
