  Checking the file status

  Oct 17, 2017 10:57 AM|maverick786us|LINK

  Process[] process = Process.GetProcessesByName("excel");
  foreach (Process excel in process)
  {
  excel.Kill();
  
  }
  process = null;

  I am using this program to kill Excel process. Before killing i want to find out, for how long is the file open. How can i accomplish this?

  Hi,

  If you look at the documentation for the Process class, you'll see you could try https://msdn.microsoft.com/en-us/library/system.diagnostics.process.starttime(v=vs.110).aspx

  Trying to use Excel on a web server is one of the very last thing I would ever try. If you can use a programming Library such as Open XML SDK or some other Library that deals with this file format.

  If for now you tried only on your own machine, keep in mind that once deployed on a real web server it will run server side ie you won't be able to control a client side Excel instance this way if this is what you are trying to do.

  Hi  maverick786us,

  For you problem, you could get StartTime for each process.

  Then you could get difference between the StartTime and current time:

              Process[] process = Process.GetProcessesByName("excel");
              foreach (Process excel in process)
              {
                  DateTime dt = excel.StartTime;
                  DateTime dt3 = DateTime.Now;
                  TimeSpan ts2 = dt3.Subtract(dt);
                  Response.Write(ts2);
                  excel.Kill();                                       
              }
              process = null;

  What happens is the users who are uploading, downloading the file, when they open those excel files in their client machines, i don't know why it creates those process in the server. If I don't kill that process, the end users face problems while opening the files again.

  You could take a try.

  It's really unclear. So far your only worked on your own machine ?

  Your code will search an Excel process on the web server side and will have absolutely no effect at all on client side Excel instances.
