Web reference can't read base class from class library in web service

[OiNutter]

Hi

I have a web service with a reference to a class library with 2 classes;

User: The base class
Client: Inherits from User

There are also some functions which return an object of type client.

When I test the web service in a browser it all works fine but when I try and add the web service as a web reference called MercuryWeb to a windows form application I get the following error message.

error C2504: 'MercuryWeb::User' : base class undefined

Fairly new to c++ and c# programming so have absolutely no idea why this is happening if the class is defined in the class library.

Any help would be greatly appreciated.
Cheers!

error C2504: 'MercuryWeb::User' : base class undefined

I would need to see your class definition and the line of code that produces this error.

On the surface, it appears you are deriving MercuryWeb from User but in that there is no definition of User. Maybe you need a #include for the file that defines User??

User Class

using System;
using System.Collections.Generic;
using System.Text;

namespace UserClassesC
{
public class User
{
private UInt32 id;
private string name;
private string username;
private string password;
//private string categories;
private string testString;

public User()
{
//
// TODO: Add constructor logic here
//
}

public UInt32 ID
{
get
{
return this.id;
}
set
{
this.id = value;
}
}
public string Name
{
get
{
return this.name;
}
set
{
this.name = value;
}
}

public string TestString
{
get
{
return this.testString;
}
set
{
this.testString = value;
}
}
public string Username
{
get
{
return this.username;
}
set
{
this.username = value;
}
}
public string Password
{
get
{
return this.password;
}
set
{
this.password = value;
}
}

}

}

Client Class

using System;
using System.Collections.Generic;
using System.Text;

namespace UserClassesC
{
public class Client : User
{
private System.Collections.ArrayList clientCategories;

public Client()
{

clientCategories = new System.Collections.ArrayList();

}

public System.Collections.ArrayList ClientCategories
{
get
{
return this.clientCategories;
}
set
{
this.clientCategories = value;
}
}
}
}

There is no function as such that produces the error, it happens when I try and add it as a web reference to a windows form app, when it tries to build the header file. The classes are defined in a class library which I've compiled to a dll file and added a reference to in the website project, would I still need to include the file as well?

This is C#. I am moving this to the .NET forum.

whoops, yeah sorry. My windows form is in c++, but the web service was started by one of my colleagues and he did it in c#.
