C#

public void GeneratePDF()
{
    Microsoft.Office.Interop.Word.Application wordApp = null;
    
    Microsoft.Office.Interop.Word.Document doc = null;

    object visible = true;
  //  object readOnly = true;
    object sourceFilename = this._sourceDocFileNameFullPath;
    string targetFilename = this._destPDFFilePath;
    object saveChanges = false;

    try
    {
        wordApp = new Application();
        
        doc = wordApp.Documents.Open(ref sourceFilename, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
                                              ref missing, ref missing, ref missing, ref  missing, ref  visible, ref missing, ref missing,

        doc.ExportAsFixedFormat(targetFilename, WdExportFormat.wdExportFormatPDF, false, WdExportOptimizeFor.wdExportOptimizeForOnScreen,
                                WdExportRange.wdExportAllDocument, 0, 0, WdExportItem.wdExportDocumentContent, false, false,

    finally
    {
        if (doc != null)
        {

        }
        if (wordApp != null)
        {
            wordApp.Quit(ref saveChanges, ref missing, ref missing);
        }
    }
}

What's the problem with your code ? Do you have an error ?

Hi Ahmed,
Thanks for the reply but the real problem is while saving word document to a PDF it should be saved as secured pdf, means it should say as secured in the title bar of the document.

You either need to use the free libraries to build the PDf file if you wish to create it programatically or you can use third party tools like cute pdf to generate the pdf file from word after it is created

You may try with this:

C#

using Microsoft.Office.Interop.Word;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;

...

// Create a new Microsoft Word application object
Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();

// C# doesn't have optional arguments so we'll need a dummy value
object oMissing = System.Reflection.Missing.Value;

// Get list of Word files in specified directory
DirectoryInfo dirInfo = new DirectoryInfo(@"\\server\folder");
FileInfo[] wordFiles = dirInfo.GetFiles("*.doc");

word.Visible = false;
word.ScreenUpdating = false;

foreach (FileInfo wordFile in wordFiles)
{
    // Cast as Object for word Open method
    Object filename = (Object)wordFile.FullName;

    // Use the dummy value as a placeholder for optional arguments
    Document doc = word.Documents.Open(ref filename, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing);
    doc.Activate();

    object outputFileName = wordFile.FullName.Replace(".doc", ".pdf");
    object fileFormat = WdSaveFormat.wdFormatPDF;

    // Save document into PDF Format
    doc.SaveAs(ref outputFileName,
        ref fileFormat, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing,
        ref oMissing, ref oMissing, ref oMissing, ref oMissing);

    // Close the Word document, but leave the Word application open.
    // doc has to be cast to type _Document so that it will find the
    // correct Close method.                
    object saveChanges = WdSaveOptions.wdDoNotSaveChanges;
    ((_Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
    doc = null;
}

// word has to be cast to type _Application so that it will find
// the correct Quit method.
((_Application)word).Quit(ref oMissing, ref oMissing, ref oMissing);
word = null;
