As the excpetion says
Access denied, meaning whoever starts your application don't have the permission to kill the other application. Your chance is to run your application with elevated privileges.What the solution then, please ?
Your chance is to run your application with elevated privilegesYou means
Run as Administrator ?I do
I did it for the
.exe of the app but still the same issue also I run the Visual Studio as Administrator but the same issueWell, are you trying to kill a
Windows Service ran by local system account ?
Next question, why are you trying to kill your own process?
It would be better to use an IPC to communicate with your very own processes or implement a Watcher inside each DRPC.
On the other hand, use a real Worker or Service template instead of a console application.I try to kill my services when there is no need to use them, and for realeasing/free up thier holded resources (RAM, CPU)
Daaaaamn, I remember somthing, I have
COMODO Firewall on my pc and I set my DRPC apps as Windows applications, is there could be a cause of the issue ?I'm not familiar with COMODO, but inter-process-communication lets you communicate programmatically with your application/processes, so you could send a shutdown command and the application could exit in a normal manner, instead being killed from the outside.
This could also be achieved by using a
Watcher inside each DRPC, for instance, in ExcelDRPC, if excel not running Environment.Exit(0).
Besides this, your project could be a single Windows Service monitoring all of the Applications you want; also it would be easier to determine if there's already another application, of your monitored applications, opened and sent to discord.Monitoring processes on
Windows OS, can be done either through Timers or using WMI and the specific built-in classes like ManagementEventWatcher. See: https://learn.microsoft.com/en-US/dotnet/api/system.management.managementeventwatcher?view=netframework-4.7.2ManagementEventWatcher Class (System.Management)
Subscribes to temporary event notifications based on a specified event query.
The specific
WQL would be something like
ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStartTrace")) and
ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace"))
for a process being started and stopped.Massive thanks I really appreciate your time and help,
I don't even knowwhy I didn't make them work as a single app
that looks a good idea
