Problem with closing other instances of my application

Please understand that it is bad advice to use Kill. The Kill documentation says "Kill causes an abnormal process termination and should be used only when necessary.". It should not be used as the normal solution.

Are you sure you need to close the previous instance? Usually single-instance applications are implemented by closing new instances instead of old instances. It is likely that could be done here too.

Since you have the code for the application, a better solution would be to use inter-process communication. If it were me, I would use something more reliable than the process name for finding existing instances. I realize that it is likely good enough for personal use but if it were me I would prefer something more precise even for personal use.

Okay, i found out its the name of the process, where something is wrong, because i tried replaceing it with "notepad" and it shut down notepad.

Okay.. i found it the code inside my foreach is ignored for some reason??

Hi Vulpes,

I now tried to replace CloseMainWindow with Kill - same result. Both the new and the old instance keeps running - any ideas?
Please tell if i should post more code.

If i take this pice of code:

Process[] Denlillehjaelper;
  Denlillehjaelper = Process.GetProcessesByName("Den lille hjælper"); 
  foreach (Process MyProcess in Denlillehjaelper)
  {
  MyProcess.CloseMainWindow();
  MyProcess.Close(); 
  }


and put it in my form_load - then it exits the application fine, when a new one starts.
But my problem is that it shouldnt always exit, so i have this controlled with some command line arguments, but when i can see that the argument run fine, and runs my method, it means that there is a problem with the code in the method, right?
