return "hello world"

I've created a simple webservice which works in a browser, but how can i get it to return the string of "Hello World" into a vb.net application?

Have you tried the webservice example in the help, it shows you how to create a webservice to do temperature conversion, then goes on to show you how you would consume that web service

Ok, solved it.

I want to send the following back as a result from the webservice to the application but get told it's not allowed as it's not a string:

Entity.quotenum
Entity.Company name

Return Entity

How can i achieve this?

you need to return Entity, assuming Entity is an object.

so instead of:

public string SomeMethod() { .. }

the signature should be:

public Entity SomeMethod() { .. }

its all to do with the return type in this case. Entity would not be a string but an object of type - you guessed it - Entity

Erm, ok. i get that, but where does it go?

i'm using the following at the mo:

Public Function Svc1(ByVal DocumentName As String) As Calculator.ServerDocResult

How do i return it?
Is it just the same?

Return Svc1 ?

Apologies if it's simple but i can't find anything on this

to me, that code there is telling me you are returning back Calculator.ServerDocResult, correct?

SVC1 is the NAME of the function, not the return type.

so I guess....

public function Svc1(ByVal DocumentName As String) As Calculator.ServerDocResult

'Do stuff here with ServerDocResult object

return theServerDocResult

End function

have you ever developed in VB.NET? It's the same for webservices (to a certain extent I guess). :-)

so if I had a class called "Person". a Person has many attributes (properties)

  • Arms

  • Legs

  • Eyes

    if I wanted to return "A person" back to the caller from the webservice:

    public function DoGetMeAPerson(string thePersonName) As Person

    Dim thePerson as New Person()

    thePerson.Name = thePersonName

    return thePerson

    end function

    simple example, simple OO example I guess.

    in the webservice, you are creating a person object and giving this person a name, then returning this person object.

    The same would apply for your ServerDocResult.

    does this help make things clearer?

    any errors?

    At what part does it time out?

    Code from either end (caller and webservice) would be better for us to assist you

    Here's the web service code i use:

    <WebMethod()> _

    Public Function DocumentSvc1(ByVal DocumentName As String, ByVal Entities As Calculator.Entity) As ServerDocResult

    DocumentSvc1.EmailTo = S@s.com
    DocumentSvc1.Name = "SR"

    Return DocumentSvc1

    End Function

    And for the application:

    Dim Entity As New StevesWebSvcTest.uk.co.<domain>.www.Entity

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Entity.CompanyName =     "Seegfe"
    Entity.ContactName = "Steve"

    Label1.Text = Submit.B3DocumentSvc1("ServerDoc1", Entity).EmailFromAddress

    End Sub

    It times out on the Label1.Text part.

    Please use wsdl.exe tool to generate the client ofr your webservice:

    wsdl.exe http://hostname/service.asmx /language:vb

    It willl generate a vb wrappes to call the service, compile the code into your client app, and use it.

    Thanks,
