I wrote a pair of programs that communicate through the Mono.Zeroconf library. The first program just broadcasts its presence and the other program listens for instances of the broadcasting program. When the listener is running and finds a broadcaster and then the broadcaster is closed, I get the following exception:
"CallbackOnCollectedDelegate was detected Message: A callback was made on a garbage collected delegate of type 'Mono.Zeroconf.Providers.Bonjour!Mono.Zeroconf.Providers.Bonjour.Native+DNSServiceBrowseReply::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called." It seems like the object is being marked for garbage collection too soon or something. How can I keep it alive? I pretty much used a lot of the mzclient source for creating these programs, but it doesn't crash and mine does. I am not sure why. Here is a snippet of the important code: http://pastebin.com/fb91b9d2 I am creating this on Windows using .NET. -- View this message in context: http://www.nabble.com/Mono.Zeroconf-Problem%3A-Calling-delegate-after-garbage-collection-tp18534138p18534138.html Sent from the Mono - General mailing list archive at Nabble.com. _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
