flush

问题 HttpListener gives you response stream, but calling flush means nothing (and from sources it's clear, because it's actually doing nothing). Digging inside HTTP API shows that this is a limitation of HttpListener itself. Anyone knows exactly how to flush response stream of HttpListener (may be with reflection or additional P/Invokes)? Update: You can't http stream anything if you don't have a flush option or ability to define buffer size. 回答1: Flush only works in most of the System.Net

问题 I'm using Spring 3.1.1.RELEASE, Hibernate 4.1.0.Final, and JPA 2.0. Is there a way I can configure Spring transactions to commit after the transactions are executed without Java code? In other words, I would like to set flush mode to commit in either the application context file, hibernate configuration file, or persistence.xml file. My Spring transaction service class looks like @Transactional(rollbackFor = Exception.class) @Service public class ContractServiceImpl implements ContractService

问题 I understand that .NET FileStream's Flush method only writes the current buffer to disk, but dependent on Windows' disk driver and the hard disk firmware this is no guarantee that the data is actually physically written to disk. Is there a .NET or Win32 method that can give me this guarantee? So if there is power loss one nanosecond after the call to this method comes back, I can still be sure that everything is OK? 回答1: Under Windows, look at FlushFileBuffers (Win32 API). 回答2: Stefan S. said

问题 I'm generating a CSV from a link on the page and sending it back to the user. I wish to maintain the page context. This code works flawlessly for IE, Chrome and Firefox on my 2008 Dev box, however when run on Vista, Win 7 or Win 8 the file has the HTML for the page appended. I did a fair bit of reading regarding the method for delivering a file and concluded that response.flush() was the best way to go. // Convert to Bytes for Binary Write Byte[] bytes = Utils.Instance.ReadStreamToByte

问题 I started programming Rust a couple of days ago by working through the official documentation. Now I'm trying to challenge my understanding of Rust by working through the book "Exercises for Programmers" by Brian P. Hogan (The Pragmatic Programmers). The first exercise is to write a program that asks the user for a name and prints out a greeting using that name. Input, string concatenation and output should be done in three distinct steps. What is your name? Patrick Hello, Patrick, nice to

问题 I've been struggling with an annoying issue for a while. I'm trying to create Notification entities associated to InventoryItems that expire. These InventoryItems are generated automatically for users, but users can edit them and set expiry date on them individually. Upon saving, if an InventoryItem has an expiry date, a Notification entity is generated and associated to it. So these Notification entities are created when an entity is updated and hence onPersist event is not going to work.

问题 Ok so I am trying to learn C and I want my user to input a value so I am using scanf. I started off not having the flushes, because nothing was comming up until I typed in two values. Now that I have them though I get the same problem there still is no output until after I type in two numbers. Here is my code: #include <stdio.h> using namespace std; int main() { int i1, i2, sums; printf( "Enter first integer\n" ); fflush(stdout); scanf( "%d", &i1 ); printf( "Enter second integer\n" ); fflush

问题 I'm using hibernate to store a set of objects from a web service. As the object are received each I am saving them using hibernate. Receiving the objects is wrapped in a transaction and all the objects appear in the database after the final object is received. I am now trying have each object appear in the database when saved. I've tried to achieve this with getHibernateTemplate().saveOrUpdate( foo ); getHibernateTemplate().flush(); getHibernateTemplate().clear(); My understanding is this
