Tip 1 : Accessing Remote Application

Suppose you have a application MyWebApps and it is published in IIS. This application has a webpage which uses the files from a remote server to which you will get access by using separate credentials given to you.
Now you are able to open the remote server folders using Windows Explorer or Runcommand.
But you are unable to retrieve the same files while running the application.Why?

The reason is your IIS account has different user credentials say IUSR_[MACHINE_NAME].But you remote server has different username and password.So you have to give the same credentials for IIS account which you are actually using to access the client server using some software like TFS.

So change the IIS account  username and password and I am sure you are able to find the shared files.Hurrah :)

Delete Files created one week before

  public void DeleteOldFiles()
        {
            DirectoryInfo di = new DirectoryInfo(MapPath("Temp//"));
            FileInfo[] rgFiles = di.GetFiles("*.xml");
            foreach (FileInfo fi in rgFiles)
            {
                string filename = fi.Name;
                int index = filename.IndexOf("@");

                string date = filename.Substring(0, index);
                date = date.Replace("_", "/");
                date = date.Replace("-", ":");
                date = date.Replace("$", " ");
                DateTime fromdate;
                DateTime todate;
                string strFromDate = date;
                string strToDate = DateTime.Now.ToString();
                if (DateTime.TryParse(strFromDate, out fromdate) && DateTime.TryParse(strToDate, out todate))
                {
                    TimeSpan TS = todate - fromdate;
                    int daysDiff = TS.Days;
                    if (daysDiff > 7)
                    {
                        fi.Delete();
                    }
                }
            }


        }

Here all files are stored with datetime attached to them before the filename in Temp folder.
We are trying to remove the datetime part from the respective filename so that we can delete the file if it is older than 1 week.

Create XmlFile dynamically attaching Todays Date to its Name

xmlcontent is a string containg the xml data.It is used to generate xml content for the newly created xml file.

                    XmlDocument xmlDoc = new XmlDocument();
                    xmlDoc.LoadXml(xmlcontent);

                    string date = System.DateTime.Now.ToString();
                    date = date.Replace("/", "_");
                    date = date.Replace(":", "-");
                    date = date.Replace(" ", "$");
                    string filename = date + "@Test.xml";
                    FileInfo fi = new FileInfo(MapPath("Temp//") + filename);
                    FileStream fstr = fi.Create();
                    fstr.Flush();
                    fstr.Close();

                    string filepath = Server.MapPath("Temp//");
                    xmlDoc.Save(filepath + filename);
