Replacement old date value with new date value

Question

Hi there, I hope your appreciated help.

First of all I must say that I am a newbie when it comes to net language.

The platform is C#.

This is my problem.

I need replace the value of DateTime.Now.ToString("dd/mm/yyyy") in all slides of my powerpoint presentation generate in OpenXml.

Now if try my net code the new value of DateTime.Now.ToString("dd/mm/yyyy") is superimposed in the old value of DateTime.Now.ToString("dd/mm/yyyy")

If you have link for similar task, please give it me.

Can you help me? thank you in advance.
Your help would be very appreciated

Thanks for your time and hints.

Answer 2

hello


you can try it

 Uri URL = new Uri("http://sixhoej.net/speedtest/1024kb.txt");

        WebClient wc = new WebClient();

        double starttime = Environment.TickCount;

        // download file from the specified URL, and save it to C:\speedtest.txt

        wc.DownloadFile(URL, @"C:\speedtest.txt");

        // get current tickcount

        double endtime = Environment.TickCount;

        // how many seconds did it take?

        // we are calculating this by subtracting starttime from endtime

        // and dividing by 1000 (since the tickcount is in miliseconds.. 1000 ms = 1 sec)

        double secs = Math.Floor(endtime - starttime) / 1000;

        // round the number of secs and remove the decimal point

        double secs2 = Math.Round(secs, 0);

        // calculate download rate in kb per sec.

        // this is done by dividing 1024 by the number of seconds it

        // took to download the file (1024 bytes = 1 kilobyte)

        double kbsec = Math.Round(1024 / secs);

        Label1.Text = "Download rate: " + kbsec + " kb/sec";

        try

        {

            // delete downloaded file

            System.IO.File.Delete(@"C:\speedtest.txt");

            Console.WriteLine("Done.");

        }

        catch

        {

            Console.WriteLine("Couldn't delete download file.");

            Console.WriteLine("To delete the file yourself, go to your C-drive and look for the file 'speedtest.txt'.");

            Console.ReadKey();

        }
