Using Nav 2009 SP1 web service from a mobile device

GrahamHutchinson · 2009-10-06

Does anybody have a C# example of using a Nav 2009 Web Service from a mobile device,without using Dynamics Mobile (Which has been discontinued) ?

I am having a problem with setting credentials to use the service.

Start off by reviewing this: http://dynamicsuser.net/blogs/navdev/ar ... rvice.aspx. It shows the general case for how to consume a Nav 2009 web service from C#.

The question you seem to be focusing on is with authentication to the web service - I'm guessing you're getting a HTTP 401 unauthorized error, or something similar.

There are two options here:

1. Set your C# application to run in the context of the user that has permissions on the web service, then use the

NavWebService.usedefaultcredentials = true;

setting shown in the article referenced above.

However, if you're running on a mobile device, #1 could be tricky. So let's look at option #2

2. Get rid of

NavWebService.UseDefaultCredentials = true;

and use this in its place:

NavWebService.UseDefaultCredentials = false;
NavWebService.Credentials = new NetworkCredential("myUsername", "myPassword");

I think the NetworkCredential constructor also takes your domain name as a third parameter if needed.

Thanks for that Tim

I have tried doing what you suggested, but I am still unable to get a connection.

I am using the following code extracted from Lars Lohndorf-Larsen's example

using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Reflection;
using System.Net;

namespace SmartDeviceProjectLars
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            WS.web NAVWebService = new WS.web();

            NAVWebService.Credentials = new NetworkCredential("Name", "Pass");

            textBox2.Text = NAVWebService.AddX(textBox1.Text);



        }
    }
}

Because it is a smart device project "NavWebService.UseDefaultCredentials = false" is not available.

I have used the identical code in a windows application and it works perfectly.

Any other suggestions?

I was using an emulator from visual studio to test this.
I have since copied the exe file to a mobile device and it is now working OK

Thanks for your help
