Hi there. I'm back to C# and am getting by with web examples and a few books. However I'm stuck.

I've created a process and it happens to be FFMPEG

Code: C# [Select]
  1. System.Diagnostics.Process proc = new System.Diagnostics.Process();
  2.             //Some rubbish but long code removed
  3.             proc.EnableRaisingEvents = false;
  4.             proc.StartInfo.FileName = ffmpegLocation;
  5.             proc.StartInfo.Arguments = arguement;
  6.             proc.StartInfo.UseShellExecute = false;
  7.             if (showEncodingEngine)
  8.             {
  9.                 proc.StartInfo.CreateNoWindow = false;
  10.             }
  11.             else
  12.             {
  13.                 proc.StartInfo.CreateNoWindow = true;
  14.             }
  15.             proc.StartInfo.RedirectStandardOutput = false;
  16.             proc.StartInfo.RedirectStandardInput = false;
  17.             proc.StartInfo.RedirectStandardError = false;
  18.             proc.Start();
  19.             proc.WaitForExit();
  20.             proc.Close();

What I'd like to do is to have this process run in BelowNormal processor priority. I've found some things in the intelitext about it, but msdn isn't really helping me.

Psudo code would be

proc.Start();
proc.processorpriority = priority.BelowNormal;

But it isn't that easy...

Thanks for any help

proc.PriorityClass = ProcessPriorityClass.BelowNormal;
Documentation for PriorityClass class here and documentation for the ProcessPriorityClass enum here.

Hope this helps, Ehtyar.

Thanks for that. Really hard to get things like this exactly right without working code snippits

Code: C# [Select]
  1. System.Diagnostics.Process proc = new System.Diagnostics.Process();
  2. proc.Start();
  3. proc.PriorityClass = System.Diagnostics.ProcessPriorityClass.BelowNormal;
  4. proc.WaitForExit();
  5. proc.Close();
