Hi,

I have a module that allows a user to upload a file and processes it (XML). My users are complaining that everyone can see everyone else's files on the server and it contains sensitive info. A simple solution is to therefor delete the .xml file immediately after upload/processing, but I can't see a simple way to do this unless I am missing something obvious:

Here is what I have so far - this causes the file to be erased everytime, but I only want to erase it IF the user uploaded it. There doesn't seem to be an Upload event on the URL control or I could set a flag - I tried the IsPostBack but that does not work. I do not want users selecting other files already on the server and deleting them - I have to somehow workout if they have just uploaded it. It's a pity the FileInfo object does not store the UserID property or it would make life so simple:

                    string filename = txtFileName.Url;
                    if (filename.Length != 0 && filename.StartsWith("FileID="))
                    {
                        FileController fileController = new FileController();
                        FileInfo fileInfo = new FileInfo();
                        int fileID = Convert.ToInt32(filename.Replace("FileID=", ""));
                        fileInfo = fileController.GetFileById(fileID, this.PortalId);
                        validXML = xmlImport.ReadAndValidateXML(fileInfo.PhysicalPath);
                       
                        if (txtFileName.IsPostBack)
                        {
                            fileController.DeleteFile(this.PortalId, fileInfo.FileName, fileInfo.FolderId, true);
                        }

Hi Sebastian,

• Ignorance ;) I thought that using the core control would be the best way of doing it - it's worked up until now but I don't like the UI.
• Will do.

Is the control you sent the WebUpload control? I'll try it now - thanks.

Hi Rodney,

I will need to have a look into the source code myself the next days to answer your questions.
