repost: AppDomain and unexpected termination

[José Joye]

I have a library written in C (I do not have the source) and having some
callbacks exported. It is currently not that stable and write to stdout and
stderr
:-((
The idea I have is to wrap it with a C# class and instanciate an instance of
this class within a new AppDomain.

Here are my question:

Am I correct to assume that I will be able to handle cases where the library
fails. If yes, how will the main AppDomain know about a termination of the
other AppDomain?


Is there a way to redirect stdout and stderr for a newly created appDomain?


Thanks,
José

Jose,

You can use the DomainUnload event to be notified when an application
domain is about to be unloaded. If your application domain terminates
abnormally, then this should fire.

As for redirecting stdout and stderr, you don't really have to do that,
as stdout and stderr's affinnity is for the process (which the app domain
will be in). It should just work.

Hope this helps.

Thanks for your answer.

regarding my 2nd question, I had the problem that my main program was a
service. In that particular case, stdout is particulary annoying...
Therefore, I had to find a workaround. I have redirected stdout and stderr
to files using "SetStdHandle".
