Spsecurity. RunWithElevated Privileges not working

Question

This Code is working very fine with admin rights but when i tried using it with normal user didnt work.

I have also provided user full control on the virtual directory folder.

public override void ItemAdded(SPItemEventProperties properties)
     {
    base.ItemAdded(properties);    
    SPSecurity.RunWithElevatedPrivileges(delegate()
     {
    if(String.Compare(properties.ListTitle, ConstantCLS.LIB_NAME, true) == 0)
    {
     strFileName = properties.ListItem.Name;
     paramMissing =Type.Missing;
if (properties.AfterUrl.IndexOf('/') == properties.AfterUrl.LastIndexOf('/'))    
     {
     folderPath =string.Empty;    
     folderPath =HostingEnvironment.ApplicationPhysicalPath;    
     }else
     {    
     folderPath = properties.AfterUrl.Substring(properties.AfterUrl.IndexOf(
    '/') + 1, properties.AfterUrl.LastIndexOf("/") - (properties.AfterUrl.IndexOf('/') + 1));    
     folderPath = folderPath.Replace("/", "\\");
     folderPath =HostingEnvironment.ApplicationPhysicalPath + folderPath;
if (System.IO.Directory.Exists(folderPath))    
     {
     }else
     {
     System.IO.Directory.CreateDirectory(folderPath);
     }    
     folderPath = folderPath + "\\";
 }
object paramSourcePath = folderPath + strFileName;    
     paramSourceBookPath = folderPath + strFileName;    
     WebClientFunction(properties.WebUrl, properties.ListItem.Url, strFileName);
if (properties.ListItem.Name.EndsWith(".docx"))    
     { paramExportFilePath = paramSourceBookPath.Replace(".docx", "_docx.pdf");
     }else if (properties.ListItem.Name.EndsWith(".doc"))
     {
     paramExportFilePath = paramSourceBookPath.Replace(".doc", "_doc.pdf");
     }
WdExportFormat paramExportFormat = WdExportFormat.wdExportFormatPDF;
    bool paramOpenAfterExport = false;
    WdExportOptimizeFor paramExportOptimizeFor =WdExportOptimizeFor.wdExportOptimizeForPrint;

    if (wordDocument != null)    
     wordDocument.ExportAsFixedFormat(paramExportFilePath,paramExportFormat, paramOpenAfterExport,paramExportOptimizeFor, paramExportRange, paramStartPage, paramEndPage, paramExportItem, paramIncludeDocProps, paramKeepIRM, paramCreateBookmarks, paramDocStructureTags, paramBitmapMissingFonts, paramUseISO19005_1,ref paramMissing);    
     }catch (Exception ex)
     {// Respond to the error    
     }
    finally    
     {
    if (wordDocument != null)
     { wordDocument.Close(ref paramMissing, ref paramMissing,ref paramMissing);    
     wordDocument = null;    
     }
if (wordApplication != null)

     }
GC.Collect();
GC.WaitForPendingFinalizers();
    GC.Collect();
    GC.WaitForPendingFinalizers();    
     }
 sharePointSite = ConstantCLS.SITEURL;    
     properties.AfterUrl.LastIndexOf('/');
    string uploadPath = properties.AfterUrl.Substring(0, properties.AfterUrl.LastIndexOf('/') + 1);
 documentLibraryName = properties.ListTitle;
    using (SPSite oSite = new SPSite(sharePointSite))
     {
    using (SPWeb oWeb = oSite.OpenWeb())
     {
    if (!System.IO.File.Exists(paramExportFilePath))    
    throw new FileNotFoundException("File not found.", paramExportFilePath);
    SPFolder myLibrary = oWeb.Folders[documentLibraryName];
    Boolean replaceExistingFiles = true;
    String fileName = System.IO.Path.GetFileName(paramExportFilePath);
    FileStream fileStream = File.OpenRead(paramExportFilePath);
    SPFile spfile = myLibrary.Files.Add(uploadPath + fileName, fileStream, replaceExistingFiles);
     myLibrary.Update();
     }}}
    });}

Can somebody tell me what is problem in this code. I have also read somewhere that for some reason writing to text file inside RunWithElevatedPrevilages method had issues.

Thanks and Regards

A good enterprise solution to convert Office documents on SharePoint is a thrid party tool from AdLib: http://www.adlibsoftware.com/

If that is too much for your purpose you can find lots of other converters on the Internet, e.g. Bamboo and Muhimbi.

Ouch! Are you trying to use Word Interop in an event receiver! You should not! This will instantiate Word (the actual application) on the server side and this is a really scary and bad operation! Just don't do it! It's not even supported, but that's not the issue here - you server will eventually fail miserably...

Now, on to how to do it! Converting from Word to PDF is natively supported in SharePoint Server using the Word Automation Services. How to do it is documented on MSDN and a plethora of places, but I recommend you to read Mr. Zimmergrens (did you know he's wearing yellow pants :-) post on the subject: http://zimmergren.net/archive/2010/08/30/sp-2010-developing-with-the-word-automation-services-in-sharepoint-server-2010.aspx
