Kill external process in Unity
I'm trying to open an external program in Unity and kill it afterwards by using this code:
Process myProcess;
string path;
path = Application.dataPath + "movie.avi";
myProcess = new Process();
myProcess.StartInfo.FileName = "C:\\Program Files\\Windows Media Player\\wmplayer.exe";
myProcess.StartInfo.Arguments = path;
myProcess.Start();
To kill it:
myProcess.CloseMainWindow();
Opening the file works fine, but I got the following error when Unity tries to kill it:
SystemException: No process to kill.
How to solve this? Thanks.
Also you shouldn't use an absolute hardcoded path. This wouldn't work on my pc because the "Program Files" folder is called different on a german installation ;) (or any other language)
You should be able to read the full media player application path from this registry key:
[H$$anonymous$$EY_LOCAL_$$anonymous$$ACHINE\SOFTWARE\$$anonymous$$icrosoft\$$anonymous$$ultimedia\W$$anonymous$$Player]
"Player.Path"
alternatively you could use Environment.GetFolderPath to get the actual "Program Files" path.
Anyway you should check if the media player is even installed / the exe file exists ;)
Finally I got a solution:
foreach (Process p in Process.GetProcessByName("wmplayer")) {
p.CloseMainWindow();
}
I wanna kill the process in OnApplicationQuit, and this seems to be the only way it works! Thx.
Try:
myProcess.Kill();
Instead of:
myProcess.CloseMainWindow();
