com interop - COM Callable Wrapper and .NET object lifetime -

I have a C # .NET assembly that calls from the C ++ COM client when the client process explicitly calls COM If the object releases, this is the reference to CCW release, thus the .net object for garbage collection is eligible.

What if the .NET object is a stable creator that opens a log file? Is there a great solution for closing the log file without explicit requests from the client?

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ....").

If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
