PDF Expiration Date

How can i set using c# when the PDF file should be expired?

Hello,

Yes, you can set the Expiry date to the already existing PDF document using our DynamicPDF Merger for .NET product. You will need to use the JavaScript and add the JavaScript to the MergeDocument object using Add method of the JavaScripts class . Below is the sample code for it.

           // Create a PDF Document
            PdfDocument pdf = new PdfDocument(@"C:\Input.pdf");
            MergeDocument document = new MergeDocument(pdf);
            //add the java script to the string
            string expiryDate = "var LastDay = 22; var LastMonth = 05; var LastYear = 2013; " +
                         " var today = new Date(); " +
                         " var myDate=new Date(); " +
                         " LastMonth = LastMonth - 1; " +
                         " myDate.setFullYear(LastYear,LastMonth,LastDay); " +
                         " if (myDate<today) " +
                         " {app.alert(\"This file is expired\"); this.closeDoc(1);} ";
            document.JavaScripts.Add(new DocumentJavaScript("js", expiryDate));
            document.Draw(@"C:\Output.pdf");

I need to set an expiry date in PDF file from our PHP based application. Can you help me with this?

Hello,

We don’t have any products that support PHP environment and we have not tested this or any other product of ours in PHP. Since this is a .NET product, all code provided in the documentation is either C# or VB.NET and there are no PHP code samples available.
