Creating a Pdf document with submit Button and Security Privileges

Is there any update on this?


As a seperate query on top of this. Can you give me example code when creating a new PDF from scratch if i want to add a submit button to the end of the pdf but also want to set the security privelidges on the pdf so that someone can save the pdf with data in form fields and then click the submit button.

I have already tried to get this working but have had no luck as i hit an error inside the form editors save method (in the code which is not accessible). Are these steps correct?

1) Create new Aspose.PDF pdf
2) Set the Security Privelidges on the SecurityPrivelidges object
2) Save to Memory Stream
3) Load memory stream into Form Editor Object
4) Use the AddSubmit Button function to add the submit button
5) Save the FormEditor to a memory stream,

I can get the add submit button to work if i dont set the security privelidges however i cannot save the document to the disk. I can also get the security privelidges to work if i dont add the submit button to the form. However when i try and add both on the save form there is an internal error thrown inside the save method.

Any help would be appreciated.

Hi Graeme,


Thanks for additional information, I’m working over your query and will update you soon.

Best Regards,

Hi Graeme,


Sorry for the inconvenience faced. I have managed to reproduce the issue at my end and logged it as PDFNEWNET-34843 in our bug tracking system for further investigation and resolution. You will be notified via this thread as soon as it gets resolved.


Thanks for your patience and cooperation.


Best Regards,

Hi Tilal,


Is there any work around or more correct way to allow the pdf to be edited and saved as well as having a submit button on it as i am sure other people must have this working with your product as its so fundamental.

Thanks
Graeme

Hi Graeme,


As a work around, can you please try Aspose.Pdf.Facades for setting security privileges after adding submit button? Please check following documentation for details/sample code.

Set privileges on an Existing Pdf File

Best Regards,

Hi Tilal,


I have now tried this and there is no error however the security settings have no effect on the generated document. I tried setting the privelidges so the document could be saved with form fields filled in. Think this could be another bug?

Thanks
Graeme

Hi Graeme,


Sorry for the delayed response. Can you please confirm are you getting this issue while saving to stream only or in case of disk also? As I’ve tried following code and can fill in the resulted form.

DocumentPrivilege privilege = DocumentPrivilege.AllowAll;
//open PDF document
PdfFileSecurity fileSecurity = new PdfFileSecurity();
fileSecurity.BindPdf(stream);
//set document privileges
fileSecurity.SetPrivilege(privilege);
//fileSecurity.Save(stream);
fileSecurity.Save(myDir+“testsubmitbtn.pdf”);


Best Regards,

Hi Tilal,


It is both saving to disk and stream. I can input text into the fields but cannot save the file from adobe.

Is there any update on this?

Graeme

Hi Graeme,


Sorry for the inconvenience faced. I’m afraid, the reported issue is still not resolved due to some other priority tasks and it’s pending in the queue for analysis. I’ve requested the development team to share the ETA at their earliest and as soon as I get a feedback I’ll update you via this forum thread.

Thanks for your patience and understanding.

Best Regards
