With the emergence of online technologies such as the Internet, people and businesses have increased their reliance and use of these mediums as an avenue for commerce as it can be more convenient. During the transaction online, there are times when it is important to preset the web visitor's country of origin, ZIP code, ISP and domain name at the drop down list to prevent fraud and to ease the complexity of registration task. This article shows you how by using .NET Framework, it can be done.

Let us take a simple example of a user login from Canada and he needs to fill up a shopping cart. The form may be quite complex as some businesses need more information to prevent fraud. In this case, there are needs to preset certain info in the drop down list such as country of origin, ZIP code, ip and domain name of where the users login. As a result, the drop down list in this example will preset to Cananda, with the correct zip code and ip address.

In this example, we use a fully functional IP2Location .NET component available at http://www.ip2location.net/download/
IP2LocationDotNetComponent.ZIP to query country by visitor's IP address. Firstly, install the IP2Location .NET component. The IP2Location .NET component will be installed in your local drive. Next, get the IP2Location.DLL .NET component and sample database from the directory, ie. c:\Program Files\IP2Location by default. You need to add a reference to this component from your Visual Studio web project. A copy of this component will be copied into /bin directory under the project. For unregistered component, there is a random 5-second delay in one out of ten queries.

Sample Codes in VB.NET Webform.

Imports IP2Location

Private Sub Query(ByVal strIPAddress As String)

   Dim oIPResult As New IP2Location.IPResult

     Try

       If strIPAddress <> "" Then

          IP2Location.Component.IPDatabasePath = "C:\\Program 
          Files\\IP2Location\\Database\\IP-COUNTRY.SAMPLE.BIN"

          oIPResult = IP2Location.Component.IPQuery(strIPAddress)

             Select Case oIPResult.Status

               Case "OK"

                 If oIPResult.CountryShort <> "-" Then

                    Response.Write("<select name=country>")

                    Response.Write("<option value="& oIPResult.CountryShort & ">" & 
                    oIPResult.CountryLong & "</option>")
