gracefully end console app

[Frank]

Hi,
I have a console app that I want to stop gracefully by another program. The
console app already has code to intercept control-c and logoff and so on.
But how do I send a control-c to that console app from another program? The
console application is started with a Process class.

Thanks
Frank

Frank,

Why not expose a remoting endpoint which would have a method which will
call Exit on the Environment class?

Hope this helps.

Hi,


The Console app can expose several ways to communicate with it , like :
1- TCP port
2- Named piped
3- Remoting

Any of these can be used to send a "terminate" signal , then you can call
Environment.Exit or Process.Kill to force it to terminate, or do as needed
to gracefully terminate it.

In case you do not have access to modify the app you could use
Process.StandardInput to send a ctrl+c to the app

 

[Frank]

Sending ctrl+c to standardinput does not seem to work. I don't know why not.
thanks
Frank

Hi,

Does it works if you send any other character?

maybe you are not sending the correct sequence.

what about the other options I presented you with?

Hello,
I am sending a hex 3.
The console app does not have a read in it.
Don't need to, if I do a ctrl-c or close the window with the X in the
topright corner it stops gracefully.

Hi,

Well, what about a Process.Kill ?

Not very gracefully, but ...
