Process won't start minimized in c#

Question

pro.StartInfo.FileName =  @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";

pro.StartInfo.Arguments = a;
pro.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;

pro.Start();

I have this code above which starts Firefox minimized. but Firefox does not actually start minimized but as a normal window. What is the problem with my code? Do I have to sleep the thread for 100 ms ?

@AlanH Well nothing again. I have changed firefox settings in 'about:config' so that it does not pop any crashes. May be that a problem? — Dionysis Nt., Apr 17 '15 at 09:42

Try out this one :)

pro.StartInfo.FileName =  @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";

pro.StartInfo.Arguments = a;
pro.UseShellExecute = true;
pro.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;

pro.Start();

As I think this will only work if firefox is NOT running. Else it will still open firefox, but not minimized. If you want to minimize your own starting firefox if the process is already up, you will need to handle ShowWindow as described here.

Nah it didn't work. I want to start firefox minimized. There is no firefox window opened while i am doing this. — Dionysis Nt., Apr 17 '15 at 14:23

to start a process without opening a terminal windows one can do like this:

 ProcessStartInfo pro = new ProcessStartInfo();

 pro.FileName = 'pathToFile'
 pro.RedirectStandardInput = true;
 pro.RedirectStandardOutput = false;
 pro.Arguments = 'some arguments'
 pro.UseShellExecute = false;
 pro.CreateNoWindow = true; // <- imp. line
