Document Signature Field

How can I use a button to popup the Sign Document (certificate selection screen) similiar to how it is done with the Document Signature Field? Basically, do what the document signature field does but with a button instead?

I forgot to mention one other item. If for some reason it is not possible to do this with a button, is it possible to disable or set to readonly the control?

Digital Signature in Document Signature field slow

The business requirement is for users to digital sign a Dynamic PDF. Digital ID's are created using Advanced - Security Settings - Digital ID - Add ID - Create a self-signed digital ID for use with Acrobat - New PKCS#12 digital ID , from Adobe Professional.
In the PDF, the user clicks in a Document Signature field to sign the document. It takes a VERY long time for this signature process to complete.
is there a trick I am missing? Is the slowness due to the way the digital ID was created?

Unfortunately, I cannot forward the form as it contains client data.
I have tested signing another PDF I've created with 2 fields using the same the digital ID's, and the process completed quickly.
Perhaps the problem lies with the size of my form which has 20 pages with 50 fields (on average) per page.
When signing the document, the signature details appear, the "saving file" temporary status bar appears and THEN the hourglass kicks in and takes 5 minutes before control is returned. Is there validation particular to the signing process I can disable? Alternatively, can I specify which pages are certified instead of the entire document?

The document signature field is repeatable

Hi!
I use signature fields in dynamic forms in Acrobat 7 without problems. In Reader and Acrobat 8 signature field is not displayed and in designer there is a warning that is it problem "The document signature field is repeatable" ...
Does someone know how to workaround this "feature", please?
Thanks,

Document Signature - Validation Issue

This is the recent help i've been trying to get on this subject over at acrobatusers.com. You can read through the issue i'm having through here, answer that was given and my response.
Summary: Basically there are multiple text fields that are set to required, customer name, email...etc. All fields must be locked after being digitally signed (through the document signature field). When default validation pattern are used (blank) it generates an error (Customer field could not be validated). After trying regular expression script, it generates an error (Customer field could not be validated). So i tried a number of different combinations of picture clauses, and from what i'm gathering you have to know exactly how many characters are going to be typed to use that sort of validation. Which in a customer name field you have know idea what their name is going to be (unless you customize a document for each individual customer (not possible)).
If anyone could help on this problem would be a lifesaver. Thank you
::COPY OF HELP QUESTION SUBMITTED::
Apparently I'm not getting the field validation examples in the Help (F1) of Livecycle. I've been struggling to get all the fields in a collection to validate properly. Once I add a Document Signature field to the document and assign the fields to a collection, it doesn't seem to like the default validation settings if I assign the fields to 'User Input: Required' So for the name field I've tried multiple validation patterns all to no avail. My question is how to write a custom validation pattern that allows for an unknown ammount of characters in a name, email..etc. I've tried A A which only validates if the user enters J D for example but John Doe does not work. I've tried other combinations but nothing works. Any help would be appreciated.
Thank you
::ANSWER SUBMITTED BY COMMUNITY EXPERT::
A:There are a couple of things you need to look at. First, is the Acrobat Picture Clause Reference. You can find it and other LiveCycle references on this site
http://partners.adobe.com/public/developer/xml/index_arch.html
The other thing to look at is using a JavaScript validation script with a Regular Expression. Regular Expressions are much more flexible that the picture clause at doing validation.
Answered by Thom Parker on Fri, Jul 6, 2007
::RESPONSE FROM ME BACK::
Q:After reading through the Picture Clause Reference I'm certain there is no way to validate the customer name field without first knowing how many characters will be entered in. And I'm pretty sure there is no simple way of just making it "required" without a pattern to verify against.
The Document Signature Field acts pretty weird if the text field is 'required' and there is nothing to validate it against. Which all in all I just want to make sure it is filled out. Customer Name field (First and Last name) one text field.
So I tried the regular expression route, and added it to the 'Validate' section of the text field. Still I think the problem lies in the way the Document Signature field processes the 'required' fields.
Now I noticed that this only happens if I set the document signature field to lock the required fields after digitally signing the document. This is a mandatory feature the document needs to have, along with the document signature. And the custom stamp option is not a viable solution to this either, since in my field of work everything is questioned whether or not it was altered or forged in some manner. And Custom 'Forged' stamps would not be too difficult to recreate, so that idea is out of the window.
I'm stumped on this and any suggetions as to what route to take would be greatly appreciated. I can not release a document to the customers with validation error messages popping up even though the fields are filled out. Just wouldn't be professional, and down right annoying considering it validates about 15 fields, and everyone except the date and tim

Hey Robert,
I've been having the same issue where, once digitally signed, I end up having an issue with my mandatory fields returning an error '[mandatory field name] validate failed'. Is this the sort of errors you are getting? I'm also trying to find answers on this as I've tried a few things but it hasnt worked well. One thing I did was to change the mandatory field back to optional and coded my submit button using the if clause when the submit button is pressed to check if the this mandatory field is filled in.
if ((pgDetails.txtReqBy.rawValue != null) &&(pgDetails.txtReqBy.rawValue != ""))
event.target.submitForm({cURL:"mailto:[email address]?subject=New/Edit Supplier Detail Form&body=Please find attached the completed form.",cSubmitAs:"PDF",cCharset:"utf-8"});
else
xfa.host.messageBox("Requested by field MUST be filled. Pls enter your full name.");
This seems to work fine except for one thing. If first time around, I fill the form out leaving the mandatory field blank, it returns the message "Requested by field MUST be filled. Pls enter your full name." So now I go back and fill in the mandatory field and, without navigating to another field, I click the submit button, I get the same message "Requested by field MUST be filled. Pls enter your full name." as it has not picked up the new value of the field. Any idea if there is code to make it re-read the field?

Document Signatures and Submiting via email

Hi,
My issue involves submitting an email and populating a document signature.
Using javascript I've set the preSubmit field to have the following line of code:
Page1.SignatureField1.validate.nullTest = "error";
I've enabled in Acrobat Professional 8, Enable Usage Rights.
While testing the form, when I select Submit by Email I get the error saying that "At least one required field was empty on export. Please fill in the required fields (highlighted) before continuing."
All well and good as this is what I want to occur.
The problem is once I sign the the document (which is the field that I've set to be validated in the above code), then click submit via email again I still get the above error message.
I tested this with the other objects such as text fields etc, they all work fine. The problem only occurs while trying to use a document signature field.
What am I doing wrong?

You need to remember the password, Adobe software does not offer any back door or password recovery for the creator.
It is recommended that, when setting certain things for a PDF, you keep the "before" file carefully as well as the "after". These things include security, reader extensions and signatures - all things that can be impossible to undo.

Digital Signature field validation

Hello Experts,
I have designed an Interactive PDF form with a digital signature field (Document Signature Field).
I would like to know how to perform server side validation for the value entered in this field in Web Dynpro ABAP.
Thanks in advance,
Daz

Here is a link to the online help article on processing of digital signatures from interactive forms:

Digitally Sign All Signature Fields in the Active Document

I have a script which will sign a single digital signature field by the field name.
I need to revise the script so it will sign multiple/all signature fields in the active document without having to put the field name in the script, as the field names will vary with each document.
Can anyone please advise how to modify the script to sign all fields in the active document regardless of the field name?
function myOtherTrustedFunction()
app.beginPriv();
// Get and login to security handler
var oSigHdlr = security.getHandler( "Adobe.PPKLite" );
oSigHdlr.login( "123","/c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx");
// Setup Signing Properties
var chk = this.getField("Checked");
if (chk != null) {
// Apply Signature and save back to original file
var bRtn = chk.signatureSign({oSig:oSigHdlr, bUI:false, oInfo:{password:"123"}});
app.endPriv();
Any assistance will be most appreciated.

Thank you for your help, the script will now count only the signature fields which have not been signed.
I have added the second part of the script to then sign all of the blank signature fields.
The script is only signing one of the digital signature fields instead of all of the blank signature fields.
Can you please advise how I can modify the script to sign all of the blank signature fields?
var count = 0;
for (var i = 0; i < numFields; i++) {
    // Get the current field object
    f = getField(getNthFieldName(i));
    // If it's a signature field and not already signed, increment counter
    if (f.type === "signature" && !f.value) {
        count++;
var myEngine = security.getHandler( "Adobe.PPKLite" );
myEngine.login( "123", c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx" );
// Sign the field
f.signatureSign( myEngine,{password: "123"});

Javascript Code to List all Signature Fields in a PDF Document

Hi everybody,
I am doing a VB.NET application that apply a digital signature in a PDF document.
My VB.NET application invoke a javascript file that signs de document. It's working very well, but I need to pass the field name to place the signature, and this is not good!
I would like to list all the signature fields existing in my PDF file, is it possible do this with Javascript? I couldn't find in the Acrobat 8 SDK documentation.
I have installed Acrobat 8 Professional in my machine.
Thank you in advance!

Nobody knows?
Help me please!
I am reading something about a method called "event.target.name" that probably do what I need, but I couldn't use it. Am I in the right way? Any ideas?
Thanks!

It is possible to add a defined sized Digital Signature field at a certain location on the document using the Adobe SDK?

I have a need to create a Digital Signature field of the same size, in the same location, on many PDF documents over and over. I would like to do this automagically through the Adobe SDK if that is possible. Has anyone done something like this before, and if so can you briefly describe how? Thank you.

You can do this most easily with JavaScript.

Adding Digital Signature Fields to Multiple Pages in a Document

Hello,
I have a batch processing java script which will place digital signature fields in a drawing.
Sometimes the drawing could have multiple pages and the script needs to place the digital signature fields onto each page.
The problem with the script I have is that the digital signature fields are only appearing on the first page.
Can anyone please provide assistance with modifying my script so that the digital signature fields appear on every page?
// Drawing signature field rev 0
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked", "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed", "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App", "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App", "signature", i, [1783, 101, 1724, 125]);
Thanks very much.

Just index the field names:
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked"+i, "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed"+i, "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App"+i, "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App"+i, "signature", i, [1783, 101, 1724, 125]);
Tho there's no point in signing each page in the same document, tho I also see engineering folk do this. They just love signing every data sheet.
And the result will not be good. Each signature will cause a problem/alert for the previous signatures.
Care to indicate your engineering company?

Can I modify a pdf file containing a signature field prior to download?

I have a pdf file I use as a template and in my .net application I fill in a few fields using pdfstamper, iTextsharp, etc. I'm new to this.
That all works.
I also have a signature field in my document.
After I modify the fields, with the person's name, etc., I download it to the client machine, open it in Adobe Reader X, and ask the user to sign the document.
I get an error saying "This document enabled extended features in Adobe Reader. The doc hsa been changed since it was created and the extended features are no longer available......"
Is there a way for me to do what I'm trying to do? I hope this is somewhat clear. It appears that modifying the fields with itextsharp is what's causing the error to occur.

Thank you for the replies.
More specifically, here's what I'm doing. There's a desk where people come to pick up a gift card. When someone picks one up, a clerk runs this .net program, selects the persons name form a dropdown list, I modify a pdf file (using iTextSharp), by adding the person's name, the serial number of the giftcard, etc, download this file to the client desktop, where the person signs using an ePad. Then the clerk saves that pdf file.
The clerk will not be able to go into the menus and remove and/or save Reader Usage Rights. Is there a way through code that I can add Reader Usage Rights after I modify the file. It sounds from your replies that that's what I need to do.
Also, I don't really care about the official "signature", security, certificates, etc. I just want someone to be able to scribble onto the document using a signature pad.
I do have Acrobat Pro X and LiveCycle. (I assume that means I have LCR Extensions.)

How to get all signature fields in a .pdf from C#

Does anyone have some sample code that shows how to "iterate" all signatures in a .pdf from C#? Using the SDK and the Javascipt object model I know how to sign a document but I can't figure out how to "get all the signatures". Basically I want to open a .pdf file and then (from C#) find out what persons currently have signed the document. I guess I need to iterate all signature fields and then get the SignatureInfo object, or?
Anyone?
Cheers,
Calle

I am afraid this don't help me. How do I get the "data" back to C#? Looping all fields in in JavaScript is probably "easy" but I simply can't figure out how to get access to the data from C#. Any one have a suggestion on the best approach?
Thx,
CJ

Adding a signature field takes a lot of time

Case: I have a Microsoft excel sheet that I save as PDF directly from excel. I use Adobe Acrobat X PRO to create 3 signature fields on this PDF to allow document signing in Adobe Reader.
Problem: Adding a signature field in form editing mode are extremly slow. After placing the signature field, Adobe Acrobat stops responding for about 1-3 minutes. I need to do this for a lot of documents, so it's time-consuming to say the least..
Is it possible to speed up this process?

How Can I stop signature fields disappearing on my IPAD Adobe Reader 11

Hi, I am using trial version of Adobe Acrobat XI pro. I have converted a Word document to PDF. I have added text fields, Java scripts to automatically add Todays date as default, Form Reset buttons and Signature fields. File is saved as standard save. All of the above is done in Windows 7 environment. On same computer, In Adobe Reader signature fields are visible although I do not have the means to test it. When the same File is emailed and opened on an IPAD using Adobe Reader 11.2, the signature fields are missing. I intend to have my users access the file (and 30 others like this) on an IPAD. Can someone advise how to resolve the missing signature field issue. It appears that Adobe do not help with such issues as it is not considered an installation issue.

Digital signatures are not supported on mobile versions of Adobe Reader. Other PDF viewers like Readdle's PDF Expert treat them like e-signature fields, allowing the user to draw/apply their drawn signature, but this is not the same as a digital signature. Adobe Reader for iOS allows you to add an e-signature, but it doesn't use digital signature fields for this feature. Instead, you tap the screen, choose the annotations icon, and then the signature icon.

How do I delete a digital signature field?

I have Adobe Acrobat Pro 9 on Snow Leopard. I created a digital signature for a PDF file but it didn't look good, so I decided to delete it. I figured out how to delete the signature, but the signature field with the little red arrow did not delete with my signature. I want my PDF form to revert to the way it was before I created the signature. I cannot simply close the PDF without saving because I'd lose all the information I've already entered. Stupid me forgot to save before attempting the digital signature.
HOW CAN I DELETE the digital signature field? Help!

Hi SM,
The place to look for permission settings is on the Security tab of the Document Properties dialog. You can get there by selecting the File > Properties menu item and then select the Security tab.
One thing to note is if the file is Reader Enabled you will need to use the File > Save a Copy menu item to create a non-Reader enabled version of the file. You cannot edit a Reader Enabled file. As an aside, the Save a Copy menu item won't be there if the file is not Reader Enabled.
If the file was created using Designer (which is only on Windows and I know you are using a Mac) then it has to be edited in Designer.
If the file was certified, then you need to remove (clear) the certifying signature before you can edit the file, and to do that you must have access to the private key that was used as part of that signature operation.
Finally, if the file is encrypted (e.g. Password Security or Certificate Security), you can edit the file, but you have to get Acrobat to realize you are the document owner which means you need the Permissions password or or logged in using a document owners digital ID (the former is only for Password Security and the latter is only for Certificate Security).
