In this tutorial, we will create a proxy checker program which will test a list of proxies and report if they respond within a faster time. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application in C# for this tutorial by following the following steps in Microsoft Visual Studio 2010: Go to File, click New Project, and choose Windows Application. 2. Next, add three buttons for starting the checker, exporting all the reports and exporting the working reports; add also a ListBox that will contain the reports of each proxy. 3.

ListBox is a control that displays a collection of items. More than one item in a ListBox is visible at a time. You can either populate the ListBox control directly, or bind it to a collection of items. In this tutorial, i will discuss some events in ListBox such as adding and removing an item in a ListBox. So, now let's start this tutorial! 1.

This is a simple tutorial in C# on how to use the System.Net namespace to send a request and receive a response from a server. Now let's start this tutorial! 1.

Sometimes, we encounter different errors along the program whenever we executed it. For example, the file does not exist in the given path, network connections are not connected, or any errors that you have experienced when you're learning how to program. This is what we've called Runtime Errors. One way to prevent it is the Structured exception handling. In this tutorial for C#, we will used the Try-Catch-Finally statement.
