Problem is that if a non-ref counted object holds a reference to your ref-counted object, your ref count wont decrement to 0 until the non-ref counted object gets GC'd. Thus, this circumvents all of what you were trying to accomplish by implementing ref counting. >Dejan > >You can read messages from the Advanced DOTNET archive, unsubscribe from Advanced DOTNET, or >subscribe to other DevelopMentor lists at http://discuss.develop.com.
