Understanding Streams and their lifetime (Flush, Dispose, Close)

NHibernate: receiving index out of range while calling flush for insert operation

I've spent the better part of my day trying to solve this message while using NHibernate: "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" My update and delete work just fine but the call to flush after a call to save() does not work. I don't think it will be useful to post a...

Empty or "flush" a file descriptor without read()?

(Note: This is not a question of how to flush a write(). This is the other end of it, so to speak.) Is it possible to empty a file descriptor that has data to be read in it without having to read() it? You might not be interested in the data, and reading it all would therefore waste space and cycles you might have better uses for. If ...

nHibernate not loading third-level properties (non-flushable caching)

I started switching some pre-existing nHibernate code in a Sharepoint-based ASP.NET project from eager loading and a new session every database hit, to lazy loading and a session for the duration of the HTTP request, and started running into a problem. When we create an Item in this system, there are some many-to-one relationships that ...

Does reading from stdin flush stdout?

stdout is line-buffered when connected to a terminal, but I remember reading somewhere that reading (at least from stdin) will automatically flush stdout. All C implementations that I have used have done this, but I can't find it in the standard now. It does make sense that it works that way, otherwise code like this: printf("Type some...

Adding a cookie to the response in Java after the header has been flushed?

I have a custom tag that does some processing and then sets a cookie. However, the cookie wasn't being set, and I couldn't figure out why. Another developer pointed out that because we're using a template system, the point at which the tag evaluates, the response header has already been flushed as a part of an include. Since the header h...
