He guys i have been busy with work and family life, hopefully back now untill i finish this book.
am having a problem in calling a web service from a client side code.

I am typing the exact code as in the book which is as follows:

<%@ Page Title="Web Services Demo" Language="C#" MasterPageFile="~/MasterPages/Frontend.master" AutoEventWireup="true" CodeFile="WebServices.aspx.cs" Inherits="Demos_WebServices" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="cpMainContent" Runat="Server">
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">

<Services>
<asp:ServiceReference Path="~/Demos/WebServices/NameService.asmx" />
</Services>

</asp:ScriptManagerProxy>

<input id="YourName" type="text" />
<input id="SayHello" type="button" value="Say Hello" />
<script type="text/javascript">
function HelloWorld()
{
var yourName = $get('YourName').value;
NameService.HelloWorld(yourName, HelloWorldCallback);
}

funciton HelloWorldCallback(result)
{
alert(result);
}

$addHandler($get('SayHello'), 'click', HelloWorld);
</script>

</asp:Content>

Things are working fine and browser comes with a services where it allows me to enter text(my name) but when i click Say Hello button nothing happens.
Left bottom cornor of the beowser says Done but with errors on page when i click the Say Hello button.

Any help is appriciated.

Hi Tariq,

I'm the night staff while Imar is catching 40 winks, (just kidding). I'm only in ch. 8 presently, but I have played with Web Services in vb and C# for a prescription database, so your question had my interest. I think I see your problem.

I think just a syntax error 'function' misspelled.;-)

Tariq: did that fix it?

Cheers,

I got it fixed accidentally Imar by changing the webservices path but not clear why it fixed the problem.

I changed the following line:


<asp:ServiceReference Path="~/Demos/WebServices/NameService.asmx" />

TO

<asp:ServiceReference Path="~/WebServices/NameService.asmx" />

Just removed the /Demos.

My concept is not clear can you please explain, i know that it has something to do with the nameservice path.

and thanks for the ractification btcomp
Tariq

The service is located in the WebServices folder, which in turn is located in the root, not in the Demos folder. Your code tries to find a service file under the demos folder, which fails because it doesn't exist there.

Hope this helps,

Imar
