Form Filling Duplication Problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am having a major problem with the form filling abilities of QuickPDF.  I have several PDF files with form fields, that I want to fill differently.  However, when I fill a field once, every field with the same name will be filled with the same information, even in different files.

I created a simple demo to demonstrate this.  It is a Console Application compiled in Visual Studio 2010 Beta 2 and is using .NET Framework 4 Client Profile.

using System;
using QuickPDFAX0719;

namespace FormFieldError
{
    class Program
    {
        static void Main(string[] args)
        {
            QuickPDFAX0719.PDFLibrary qp = new PDFLibrary();        // Create a new QuickPDF Lib
            qp.UnlockKey("j53g73ru93q4dp4ja7ri53b4y");              // License key for the QuickPDF library (TRIAL - expires 06/23/2010)
            int mainDocument = qp.NewDocument();                    // Create a new document, store it's id
            int tempDocument;                                       // Holds the id of the loaded document

            // Get file paths
            string form1 = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), "form1.pdf");
            string form2 = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), "form2.pdf");
            string output = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), "output.pdf");

            // Fill document 1
            qp.LoadFromFile(form1);                                 // Load the form
            tempDocument = qp.SelectedDocument();                   // Get the id of the loaded document
            qp.SetFormFieldValueByTitle("RecordFileNo", "123");     // Set the file #
            qp.SelectDocument(mainDocument);                        // Select the main document
            qp.MergeDocument(tempDocument);                         // Merge the temp document into the main document

            // Fill document 2
            qp.LoadFromFile(form2);                                 // Load the form
            tempDocument = qp.SelectedDocument();                   // Get the id of the loaded document
            qp.SetFormFieldValueByTitle("RecordFileNo", "abc");     // Set the file #
            qp.SelectDocument(mainDocument);                        // Select the main document
            qp.MergeDocument(tempDocument);                         // Merge the temp document into the main document

            // Save result
            qp.SelectDocument(mainDocument);                        // Select the main document
            qp.DeletePages(1, 1);                                   // Delete the first (blank) page
            qp.SaveToFile(output);                                  // Save to disk
        }
    }
}

Opening the output.pdf file, you would expect to find the text "123" on the first page and "abc" on the second page.  However, both pages have the text "123".

Am I doing something wrong, or is there a bug in the library?  I really need to get this to work for my application, and I already have too much time invested to switch to a different PDF writer.

Thanks!
