I want to authorise a user of a web service by using the AuthHeaderValue for
some reason I keep getting a null reference exception when I try to run the
following code: It seems to work fine on a .NET Framework application, but
just not on the .NET CF version.

Can anyone suggest anything that might be wrong with the code? (I could
post the app and webservice, but i was hoping that you might have noticed
something from the supplied code).

Many thanks.



WebServices service = new WebServices();

Webservices.AuthHeader Credentials = new Webservices.AuthHeader();

Credentials.UserName = "user";

Credentials.Password = "P@ssword";

service.AuthHeaderValue = Credentials;

loggedin = service.login();

Hi Davie,

Welcome to MSDN newsgroup.
From your description, you're using the .NET framework to build a
webservice and conumse it in client app through .NET webservice proxy. You
also add a custom propety for the webservice so as to pass athorization
info. You find that this works well when in normal .net app, but always get
Null reference exception when used in compact framework, yes?

As for the AuthHeader (from the code you provided), is it a custom
SoapHeader you defined in your webservice? If so, would you provide the
detailed code of your webservice definition. Also, have you compared the
clientside proxy classes generated in the normal .net client and compact
framework client to see whether there're any difference on the soapheader
declaration?

If there're any other finding, please feel free to post here.

Thanks,

Hi Davie,

Thanks for your further response and the test application you provided. It
seems that your webservice is created in asp.net 2.0 project. Due to
environment limitation, I just have tested in a VS.NET 2003/ .NET FRAMEWORK
1.1 environment (smartphone 2003 emulator...) and found that the clientside
can correctly use the SoapHeader to send info to service. So have you also
tried this in a vs.net 2003 /.net 1.1 environment?

Thanks,

I haven't tried this in a .NET 1.1. environment, since I need my web
services to run in .NET 2.0. I am aware that the release date for .NET 2.0
is sometime in November.

I do know that the .NET 2.0 webservice works with .NET 1.1 Windows app
clients but not .NET CF 1.1. clients.

What do you suggest?

Thanks.
Davie.

Hi Davie,

Well, I've managed to got a physical machine for testing with asp.net2.0
webservice and vs.net2003 smartphone 2003 project, and did find the problem
you mentioned. After some further investigate, I found that the
NullReference exception is just thrown at clientside (no SOAP message is
sent out event). So I check the generated proxy's source file and compiled
the one with that I generated from a ASP.NET 1.X webservice and got the
cause:

when comsuming the ASP.NET 2.0 webservice, the clientproxy will generate
the following class for soapheader(AuthHeader)



[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]

[System.Xml.Serialization.XmlRootAttribute(Namespace="http://tempuri.org/",
IsNullable=false)]
public class AuthHeader : System.Web.Services.Protocols.SoapHeader {

/// <remarks/>
public string Username;

/// <remarks/>
public string Password;

/// <remarks/>
[System.Xml.Serialization.XmlAnyAttributeAttribute()]
public System.Xml.XmlAttribute[] AnyAttr;
}


Note that the
/// <remarks/>
[System.Xml.Serialization.XmlAnyAttributeAttribute()]
public System.Xml.XmlAttribute[] AnyAttr;

is the one which cause the problem, this field won't be generated for
asp.net 1.1 webservice. After comment this field, I can make the webmethod
call correctly. Also, seems this doesn't matter for normal desktop or
console application, maybe something incorrect with the webservice
implementaiton on smartphone 2003 platform's compact framework.

Anyway, I think you can manually commet/remove that "AnyAttr" field in your
proxy soapheader class to see whether it works.

Thanks,

Steven Cheng
