    Hi All, i am trying to download a file from my website on my server, but i keep getting a error: Access to the path 'c:\ImageName.gif' is denied. this is my code i am using: using (WebClient wcDownload = new WebClient()) { try { webRequest = (HttpWebRequest)WebRequest.Create("http://www.XXXXXXXXXXX.XX.XX/Images/" + strImgName); webRequest.Credentials = CredentialCache.DefaultCredentials; webResponse = (HttpWebResponse)webRequest.GetResponse(); Int64 fileSize = webResponse.ContentLength; strResponse = wcDownload.OpenRead("http://www.XXXXXXXXXXX.XX.XX/Images/" + strImgName); string strFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); strLocal = new FileStream(strFolder + "\\" + strImgName, FileMode.Create, FileAccess.Write, FileShare.ReadWrite); int bytesSize = 0; byte[] downBuffer = new byte[2048]; while ((bytesSize = strResponse.Read(downBuffer, 0, downBuffer.Length)) > 0) { strLocal.Write(downBuffer, 0, bytesSize); } string strAlert = "alert('" + strImgName + " downloaded to " + strFolder + "');"; ScriptManager.RegisterStartupScript(Page, Page.GetType(), "", strAlert, true); } finally { strResponse.Close(); strLocal.Close(); } } Any help is much appreciated. living life on the flip side

    Hi All, thanks for the replies, i haven't tried a different path yet. is there anyway i can get this download to work. all i really need to do is allow the user to download the image from the website which is hosted on the server to their local machine, preferably their desktop. living life on the flip side

      Isn't that a bit like going to the doctor and asking him to cure you but refusing to follow his advice? :confused: /ravi

        it may be OK to ask for advice, then not follow it. However asking again is a bit weird, yes. :)

            well, 1. i am not an idiot, and that was not truly called for, but anyways, 2. i did however try a new path after i posted reply, no change, still get the error. is it a permissions issue with the server accessing the local file? or is there something else i am missing? living life on the flip side

                Are you able to manually (i.e. thru the Windows UI) create a file with the same path name? That would help identify if it's a permissions issue. /ravi

                  Just for grins, does this work any better?

                  WebClient wc = new WebClient();
                  wc.DownloadFile ("http://.../foo.jpg", @"C:\MyFolder\foo.jpg");

                      I'm sorry - did I call you an idiot? If you look at the threads, I was talking to Luc, and making a generic comment about technical support phone calls. Trust me, if I wanted to insult you, you would know all about it! :laugh:

                          Sorry, I have no solution for you. Just a question: Why don't you use WebClient.DownloadFile for downloading the image? Anyway, your code seems to be correct... P.S. Have you heard about Path.Combine (because

                          +"\\"

                          doesn't look so good)

                            Is is possible that the target file has already been opened (for exclusive read or write), thereby preventing it from being overwritten?  Although I think if that were the case you'd see a different exception. /ravi
