how to secure files (pdf), the recomendation is httphandelers, it works absolutely great.But now an new issue has been arrived. What i did , i registerd ISAPI extension (.pdf) in IIS 6.0,to let process the request to ASP.Net runtime, there i used context.response.transmitfile to send the file to the browser, as client will be viewing file in browser not downloading, but in case when file is bigger than 20 MB ,(file can be upto 100MB), it takes time, obviously it should take. But when we redirect or request pdf file without registering ISAPI extension, browser starts showing file, means you see instantly first page or few pages while other are downloading, how to achive this kind of performance, and this kind of behaviour, with letting asp.net runtime process the request. I hope you guys get my question & if any explaination needed please ask. Note: Same issue with uploading files with .Net uploader control, even after we change machine.config file size attribute, i want suggestion about better performance, when many users are doing both uploading, and viewing files from repository. context.Response.Clear(); context.Response.AddHeader("content-disposition", "inline;filename=" + values[1] + ".pdf"); context.Response.ContentType = "application/pdf"; context.Response.BufferOutput = false; context.Response.TransmitFile(physicalfilepath); context.Response.Flush(); context.Response.Close(); context.Response.End();

Thanks for reply. But now i am confused to go for a reliable solution regarding file security. Its right that asp.net location tag didnot work for like it did work for common aspx pages. I read articles which advocates different solutions, like implementing basic authentication with SSL, to secure the files, and use httpwebrequest type classes to get login on the server and give access to the logined user without prompting a login diaglue. Some advocate NTLM security, which is new even i heard first time. You told me to write handelers, i read a little about it, to map IIS extensions with asp.net extension to restrict file access in browser. But my real problem is i will be having thousands of files, and with hunderd of users having different writes on them, I am looking to having a reliable solution which should also be good in performance. Can you please put little more light regarding my context explained above. I will be very thankful to you. Many Thanks & Best Regards, adnan

Hi, This provides usefull methods to get tempfiles, unuque name, and temp directory paths, i m wondering if i can show my files let say in folder "PDF", which is not publicaly viewable, in that temp file, which is unique for each user session. Problem: I have pdf files in PDF folder on which each asp.net user have different rights, some can view the same files and some can not, so i planned to make it restricted for all user, and will get rights from the dataabse, and finally i want to copy these file to uniquly created temp file, and want to redirect to that file, so user can see the file in browser. i hope you understand my question. many thanks adnan -- modified at 10:39 Sunday 26th August, 2007

Hi All, I have two datatables, one datatable named "dtRecords1" gets filled from excel sheet, having column name "Name","Category", and on run time i have added a Identity column to "dtRecords1". Second Column gets filled from sql server database having three columsn "ID as Identity","Name","Category". Now i want to merge these two tables, i want this result from merge. If there are some changes in first datatable, depending upon all columns (comparing all column values) and ID Is same,it should be overwrited, and if there are some new rows these also should be added to the resulted database. Example: Datatable1 from excel ID,Name,Categoey 1,adnan,SE 2,ali,SSE 3,Imran,JSE Datatable2 From SQL Server DB ID,Name,Category 1,adnan,SSE 2,ali,SSE Resulted Datatable ID,Name,Category 1,adnan,SE -Changed ROw 2,ali,SSE -Unchanged Row 3,Imran,JSE - Newly added Row Many THanks & Best Regards, adnan
