Visual C# .NET IPtoCountry Sample Source Code

ActiveSocket provides an easy-to-use development interface to a variety of IP protocols. By using ActiveSocket, you can very easily create or enhance applications with network features.

ActiveSocket features the following: ICMP, HTTP and HTTPs with support for proxy servers and secure web sites, Telnet, NTP time protocol, RSH remote shell script interface, SNMP (Simple Network Management Protcol), SNMP Traps, Sockets (TCP and UDP), WOL (Wake-On-LAN), IP to country lookups and more.

The ActiveSocket Toolkit can be well integrated into .NET environments.
This document describes how the ActiveSocket Toolkit can be integrated into into Visual C# .NET projects.

Step 1: Download and install the ActiveSocket Toolkit

Download the the ActiveSocket Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new Visual C# .NET Project

Launch Microsoft Visual Studio (for instance 'Microsoft Visual Studio 2005') from the Start menu. Choose 'New' from the 'File' menu and click on 'Project'. In the 'New Project' dialog, select a Visual Studio template (for instance: 'Console Application'). Select a name for the application (for instance: 'DemoApp') and a name for the solution (for instance: 'DemoSolution'). Also, select the directory where you want to store the project (for instance: 'C:\MyProjects):

Step 3: Refer to the ActiveSocket Library and create the objects

Now that a new project has been created, you must add a reference to the ActiveSocket Toolkit in the project to be able to use the ActiveSocket object. To do so, choose 'Add Reference...' from the 'Project' menu. In the 'Add Reference' dialog that pops up, select the 'COM' tab and select the 'ActiveSocket 3.1 Type Library' as shown in the following picture:

Click 'OK' to close the 'Add Reference' dialog.

On top of your code, type the following line to use the ActiveSocket namespace:

   using ASOCKETLib;

In your Main function, declare and create the following object:

   public IPtoCountry m_objIPtoCountry;
	
   m_objIPtoCountry = new IPtoCountry ();

Step 4: Perform an IP address to country lookup

You can now use the ActiveSocket SDK to do an IP address lookup.

The following code shows how to create a simple IP to country lookup utility using Microsoft Visual C# .NET:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using ASOCKETLib;

namespace Demo
{
	/// <summary>
	/// Summary description for IPtoCountryForm.
	/// </summary>
	public class IPtoCountryForm : System.Windows.Forms.Form
	{
		internal System.Windows.Forms.GroupBox GroupBox1;
		internal System.Windows.Forms.Button ButtonView;
		internal System.Windows.Forms.Button ButtonQuery;
		internal System.Windows.Forms.TextBox TextLogFile;
		internal System.Windows.Forms.TextBox TextResult;
		internal System.Windows.Forms.TextBox TextCountryCode;
		internal System.Windows.Forms.TextBox TextCountry;
		internal System.Windows.Forms.TextBox TextHost;
		internal System.Windows.Forms.Label Label5;
		internal System.Windows.Forms.Label Label4;
		internal System.Windows.Forms.Label Label3;
		internal System.Windows.Forms.Label Label2;
		internal System.Windows.Forms.Label Label1;
		/// <summary>
		/// Required designer variable.
		/// </summary>
		private System.ComponentModel.Container components = null;



		public IPtoCountryForm()
		{
			//
			// Required for Windows Form Designer support
			//
			InitializeComponent();

			//
			// TODO: Add any constructor code after InitializeComponent call
			//
		}

		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			if( disposing )
			{
				if(components != null)
				{
					components.Dispose();
				}
			}
			base.Dispose( disposing );
		}

		#region Windows Form Designer generated code
		#endregion

		/***************************************************************************/

		private IPtoCountry	objIPC;

		private void ButtonQuery_Click(object sender, System.EventArgs e)
		{
			objIPC.LogFile = TextLogFile.Text;
			objIPC.Host = TextHost.Text;
			objIPC.Query();

			TextResult.Text = objIPC.LastError + " : " + objIPC.GetErrorDescription(objIPC.LastError);
			TextCountry.Text = objIPC.CountryName;
			TextCountryCode.Text = objIPC.CountryCode;
		}

		/***************************************************************************/

		private void ButtonView_Click(object sender, System.EventArgs e)
		{
			if (System.IO.File.Exists(TextLogFile.Text.ToString()))
			{
				System.Diagnostics.Process.Start(TextLogFile.Text);
			}
		}

		private void IPtoCountryForm_Load(object sender, System.EventArgs e)
		{
			objIPC = new IPtoCountry();
			TextLogFile.Text = System.IO.Path.GetTempPath() + "IPtoCountryLog.txt";
		}

		/***************************************************************************/
	}
}

There are many working samples included with the product. You can also find them on the ActiveXperts FTP site: ftp.activexperts-labs.com/samples/asocket.

NOTE: Demo Projects are created with Microsoft Visual Studio 2002

The ActiveSocket project ships with a set of Microsoft Visual Studio .NET samples, including samples for Microsoft Visual C# .NET. The projects are created with Microsoft Visual Studio 2002.
Users with a later version of Microsoft Visual Studio can open such a project. The Visual Studio Conversion Wizard will guide you through the process of converting the project to the version used.
