Help with Hello World?

Andy Barlow

12/31/2002

I'm trying to get a handle on ASP.Net web services, and am getting nowhere
fast. Any help would be appreciated



To begin with, I created a webservice and uncommented the HelloWorld code
from the example. The file : Service1.asmx is added to my solution:

Imports System.Web.Services

<WebService(Namespace := "http://tempuri....)> _

Public Class Service1

Inherits System.Web.Services.WebService

#Region " Web Services Designer Generated Code "

. . .

#End Region

' WEB SERVICE EXAMPLE

' The HelloWorld() example service returns the string Hello World.

' To build, uncomment the following lines then save and build the
project.

' To test this web service, ensure that the .asmx file is the start page

' and press F5.

'

<WebMethod()> Public Function HelloWorld() As String

HelloWorld = "Hello World"

End Function

End Class





Now, in my client code I have the following:



Dim strSave as string

strSave = HelloWorld()



I have alternatively tried using:



Dim strSave as string

strSave = Service1.HelloWorld()



In each case I get the following:

===========================================================

Compiler Error Message: BC30451: Name 'HelloWorld' is not declared.

Line 87: Dim strSave as string

Line 88:
Line 89: strSave = HelloWorld()
Line 90:
Line 91: if(ClientList.SelectedIndex = 0) then

====================================================================



Whar am I doing wrong here?



Thanks.

You need to create an instance of Service1 first, then use it to call
HelloWorld..

Thanks. I tried that but then I get the error:

Compiler Error Message: BC30002: Type 'Service1' is not defined.

How do I get the ASP page to recognized the external mathod?

Thanks again.

You are missing some steps

First you need to create a WEB REFERANCE

Then you need to declare an instance of the class. The code will look
something like the following:

Dim ws As localhost.Service1 = New localhost.Service1()

Dim szString as String

szString = ws.Service1()



Look on Google for tutorials on how to create a web service.
