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

推荐答案

显然，您只需要一个按邮政编码的城镇数据库（但是如何在更改完成后更新它？）或使用一个或另一个Web服务（甚至是一个站点）来获取这些数据。例如：

http://www.webservicex.net/uszip.asmx [< a href =http://www.webservicex.net/uszip.asmxtarget =_ blanktitle =New Window> ^ ]，

http://www.webservicex.net/uszip.asmx?WSDL [ ^ ]。



如你所见，这是常规Web站点和Web服务。由于你有WSDL，这不会是一个问题：

https：/ /msdn.microsoft.com/en-us/library/dd355316.aspx [ ^ ]，

https://msdn.microsoft.com/en-us/library/d2s8y7bs%28VS.100%29.aspx [ ^ ]，

并非所有服务都是这样的。在这种情况下，请阅读他们的API文档。您可以使用类 HttpWebRequest 处理低级别的任何Web资源。

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.

所以这是我的解决方案...

So here is my solution...

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
