Connections & Close Exceptions

[ConvertFromOldNGs]

Is the only way to tell whether a NamedPipe (or other types of connection?) has been closed by other other side is to catch the appropriate exception in a global exception handler?

Im using asynch calls, so there is no way to surround it with a local exception handler and it seems there is no callback for a close initiated by the other side.

Thanks,

Wilfred.

I think you're right. If the main thread has gone idle then any local exception handlers will have been disarmed. Certainly, for CardSchema's CnTcpConnection class I found I had to use a globally armed handler to catch exceptions. I don't know of any alternative to this.
