Hi all,
I am writing a proxy server in C# and it crashes (fairly) often. I have my code in a try catch block and I catch all the types of exceptions it throws. But I am looking for a clever way to relaunch the program when this happens as it dies.
It is a C# Console Application in .NET 2005.
Any help is appreciated.
Thanks alot,
Nick

You really should be working to solve the problems that cause it to crash.
There's really not any reason a thrown error should stop your program, you just need to put try catch blocks in correct places.
As for your question though, if it's installed as a windows service, the service controls (services.msc) has a whole section on "what to do if program is stopped" (reboot pc, reload program, do nothing, etc)
Its not installed as a windows service, just a console application I want to have constantly running. I definitely do want to try to avoid these exceptions but in the mean time would like to find the best practice on how to do this.
When I catch the error, I try to create a new instance of the class but it doesn't start correctly. Could you tell me the best way to re-instantiate the object? The catch is made at the end of the code...
Thanks in advance
Nick
Can you shrink the try-catch blocks to encapsulate smaller bits of code?
For instance if I have a socket listening for requests, I would put that in a try-catch. BUT I would also put the code where I handle communication with a socket connecting to me in a different, smaller, try-catch block. Then you can perhaps recover from the error without having to restart from the begining. (For instance when a user kills a connection before I am done responding, it throws an IOException, but it doesn't effect my listener socket)
What you could try and do is make a tiny little program, thats sole job is too look at the proccesses that are running and if your application isn't running, re-open it. You could always close that 2nd little application when you ACTUALLY want your program to stop.
Plater,
This idea is one that I've definitely had but not sure how to implement. Do you have any idea to access the processes (like Task Manager), see if it is running or not and if not relaunch the app?
I'll try putting smaller try/catches too.
Thanks again
Nick
thanks alot plater...i think this will work just great
Could you perhaps post your code? I for one am curious as to what code you have that is causing these issues.
