How to set a field as 'office use only'

Question

Hello all,
I have one more question for you. 
I sometimes send forms out that must have information set in the fields. The problem is that I don't want the people I send the forms to to change this information. Is there an easy way to do this?
Thanks,
Tristan

This is EXACTLY what I would want. Where do I set up a bookmark?
I changed the prefixes to private.NAME and copy paste the code into a button that executes Java but it didn't work. Sorry, I'm such a noob at this.
Both suggestions seem good, but I would
have about 10 or more fields that I would need to change everytime I send or recieve the pdf.
Is there a way to make the process easier? The form I'm trying to make would also need to be used by other people in the office who are not as tech savy as I am... and that is not saying much.
There are a number of ways. Probably the simplest is to set up a bookmark that prompts the user for a password. If correct, it would lock/unlock the fields. This would all be implemented in JavaScript. You can do the same type of thing though the use of a custom menu item or toolbar button.
Try something like:
(function () {
    // Get one of the fields in the group
    var f = getField("private.name");
    // Determine new readonly state, which
    // is the opposite of the current state
    var readonly = !f.readonly;
    var readonly_desc = readonly ? "deactivate" : "activate";
    // Ask user for password
    var resp = app.response({
        cQuestion: "To " + readonly_desc + " the fields, enter the password:",
        cTitle: "Enter password",
        bPassword: true,
        cLabel: "Password"
    switch (resp) {
    case "your_password": // Your password goes here
        getField("private").readonly = readonly;
        app.alert("The fields are now " + readonly_desc + "d.", 3);
        break;
    case null : // User pressed Cancel button
        break;
    default : // Incorrect password
        app.alert("Incorrect password.", 1);
        break;
In this example, the fields that are controlled by this all have a field name prefix of "private", for example "private.name", "private.address", etc. This makes it easier to control the fields as a group, as I do in the line of code that begins: getField("private").readonly  If you don't use such a field naming convention, you'd have to have a separate such line for each field in the group.
Replace "your_password" above with one of your own. The first and last lines are not necessary, but do prevent the needless creation of document-global variables, which is a good thing.
