Hello Experts,

Is there any way that I can auto fill City and State with Zip code ?

I wanted to use something really simple.

I have seen some results in google where most of them were with AJAX calls, which we don't want to do it.

I would appreciate tutorials/ code/ referral link.

I am also open to suggestions

Thanks

Apparently, you just need a database of cities/towns by zip codes (but how can you update it when changes are done?) or use one or another Web service (or even a site) to fetch this data. For example:
http://www.webservicex.net/uszip.asmx[^],
http://www.webservicex.net/uszip.asmx?WSDL[^].

As you can see, this is both a "regular" Web site, and a Web service. As you have WSDL, this won't be a problem:
https://msdn.microsoft.com/en-us/library/dd355316.aspx[^],
https://msdn.microsoft.com/en-us/library/d2s8y7bs%28VS.100%29.aspx[^],
http://www.sitepoint.com/net-web-services-5-steps[^].

Not all services work like that. In such cases, read their API documentation. You can work with any Web resource on low level using the class HttpWebRequest.

So here is my solution...

VB

Dim ds As New DataSet()
       Dim url As String = "http://maps.google.com/maps/api/geocode/xml?address=" + txtZip.Text + "&sensor=false"
       Dim request As System.Net.WebRequest = System.Net.WebRequest.Create(url)
       Using response As System.Net.WebResponse = DirectCast(request.GetResponse(), System.Net.HttpWebResponse)
           Using reader As New System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8)
               ds.ReadXml(reader)
               Dim dt As DataTable = ds.Tables("result")
               Dim strspliaddress = dt.Rows(0)("formatted_Address").ToString().Split(",")
               txtcity.Text = strspliaddress(0)
txtState.Text= strspliaddress(1)'Something like this
