cannot establish a connection to the network PocketPC 5.0

Hello,

VS 2005

I have created a Pocket that uses a web service to get data from a SQL server.
I have created the web refererence to the web service.

I am developing a pocket PC in WM 5.0

However, when I click a button on the PDA to get the data I get this error message "Cannot establish a connection to the network"

I am using active syn and have and using the emulator. This has been connected ok.

I have also configured the emulator from File | configure | Network and checked host only network. ( I don't think this makes much difference as the pocket 2003 i developed, it did not make much difference, as it worked if it was checked or not).

The code that causes the error is below:

Code:

---

Try
            Dim ws As New DataIncidents.Service()
            Dim ds As New DataSet

            ds = ws.getIncidents()
            'Dim cnnStr As String
            'cnnStr = ws.getIncidents()

            Me.grdIncidents.DataSource = ds.Tables(0).DefaultView

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

---

If I add the Url line in, it works ok

Code:

---

Try
            Dim ws As New CodeRed.Service()
            ws.Url = "http://1.1.1.1/Incidents/Service.asmx" 'Works with this line
            Dim ds As New DataSet

            ds = ws.getIncidents()
            'Dim cnnStr As String
            'cnnStr = ws.getIncidents()

            Me.grdIncidents.DataSource = ds.Tables(0).DefaultView

        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

---

Its not good to have this line hard coded in the program as if the location is changed then the problem will no longer function.

Can anyone tell me why I am getting this error.

Many thanks in advance,

Steve
