How do I pass a message or variable to a web service?

[needin4mation]

I have this in my web service:

public XmlDocument GetDataFromDB(string name)
{
....
do some stuff with name variable..on the database...
return the XmlDocument to my datagrid;
}

Now, in my client default.aspx I have a button that calls this
function:

public void DataBindFrmWS(string name)
{
try
{
XmlDocument myServiceDoc = new XmlDocument();
System.Xml.XmlNode neNode;
//Adding the resulting XML from WebMethod to a user created
XmlNode
neNode = myService1.GetDataFromDB(name); //from above
....

It breaks on this last line when compiling saying:

"No overload for method "GetDataFromDB' takes '1' arguments."

What does this mean?

I read that I should think not of this as passing variables as in
functions calls, but sending messages. I can't figure out how to send
this simple message. I only want to send a simple string with a last
name.

Thank you for any help.

Well, I would disagree that you should think of web service calls as
"passing messages". You should, in fact, think of them as remote procedure
(function) calls. If the webmethod requires a parameter, then you must pass
one to the function.

Are you sure that your web service project has been re-built and than your
web service reference has been refreshed?

Scott, remember that there are two styles of web service: the RPC style, and
the Document style. Some like the latter, for generality (I do).

I'm sorry John, I don't know what you mean by "document style" web service.

Any idea on how to pass the variable to the service? Anyone? Thank
you again for any help.

Hi,

Can you pass the entire code, as from your code it doesn't seems you have
done anything wrong. It must be related to the settings or environment...or
something else

I'm sorry John, I don't know what you mean by "document style" web
service.

In the <wsdl:bindingsection, if you use <soap:binding style="document"
/>, then you are effectively saying that you want the messages in this
binding to be considered, each, as a single XML document, as opposed to a
set of RPC-style parameters. The single document can represent multiple
parameters, and, depending on your platform, can be processed as multiple
parameters.This allows you to think in terms of sending and receiving entire
XML documents, possibly complicated ones, instead of restricting your
thinking to a flat set of procedure call parameters.

That's probably way too much code, but here is someone that had the
same problem:

http://groups.google.com/group/micro...c244dfa9208c7f

That is where I got part of my information from.

Here is the code up to that point in my .asmx:

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Runtime.InteropServices;
using System.Data.Odbc;
using System.Configuration;
using System.Diagnostics;
using System.Data;
using System.Xml;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service () {

//Uncomment the following line if using designed components
//InitializeComponent();
}

[WebMethod]
public string HelloWorld() {
return "Hi";
}
[WebMethod]
public XmlDocument GetDataFromDB(string name)
{
string errorMessage = "";
XmlDocument myDatas = new XmlDocument();
....

In my client .aspx:

protected void Button1_Click(object sender, EventArgs e)
{

DataBindFrmWS(TextBox1.Text);

}

Thanks again for any help. Everything works, as long as I don't pass
it a variable.

I finally got it working. I looked at the WSDL and found this:

<s:element name="GetDataFromDB">
<s:complexType />
</s:element>

So I went to Visual Studio and updated my web reference and it produced
this:

<s:element name="GetDataFromDB">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="name"
type="s:string" />
</s:sequence>
</s:complexType>
</s:element>

I guess I need understand how all the pieces work together better.
Thanks.

But you still, are, in fact, calling procedures and receiving back function
return values. The transport mechanism may be a complete XML document, but
what you are doing (why you are using the services) doesn't change
fundamentally.

If you look at my first response to your question and the last thing I
wrote, you'll see that I had already suggested that:

"Are you sure that your web service project has been re-built and than your

How do you know that you're calling a procedure? You could, for instance, be
calling a BizTalk orchestration, or something equally bizarre.

[Scott M.]

Well, I would characterize any process that needs to be invoked a procedure.

procedure.

Sending a message is, then, also invoking a procedure.
Since it requires invoking a method to pust it to the wire and somebody on
the other side to grab it and process it -- of course, a method involed
Just my few thoughts

Well no, not really. Sure, you need to invoke a method to post a message,
but that method works on a local object, web services invoke a remote
object's method.... A bit of a difference. I can send and receive XML
messages quite easily and never get near web services. In other words,
sending and receiving XML messages does not constitute web services.
