Add Group Collapse Behavior on a Listview Control

Introduction

ListView control is an important but complex control in the WinForm environment. Group behavior is added into this control, but unfortunately, we can't collapse or expand the group.

I'll show how to use some simple code to add collapse/expand behavior on the ListView control.

This is a sample image on Windows Vista and Windows Server 2008:

Asynchronous Socket Programming in C#

Objective The objective of this article is to demonstrate a socket-based client/server application that will allow two-way asynchronous communication between a server and multiple client applications. Because this example uses asynchronous methods, the server application does not use threads to communicate to multiple clients (although internally the asynchronous communication mechanism uses threads at the OS level). The Difference Between Synchronous and Asynchronous Communication in Network Programming The key difference between synchronous and asynchronous communication can be explained with an example. Consider a server application that is listening on a specific port to get data from clients. In synchronous receiving, while the server is waiting to receive data from a client, if the stream is empty the main thread will block until the request for data is satisfied. Hence, the server cannot do anything else until it receives data from the client. If another clien
