ok, I have this code that worked as a windows application, aka it connected to the WebService and did what it was supposed to do. But I wanted to port the same thing to a PDA and I can't get it to connect, I keep getting a webexeption when I run it.
public class Form1 : System.Windows.Forms.Form
	{
		private System.Windows.Forms.Label label1;
		private System.Windows.Forms.Timer timer1;
		private System.Windows.Forms.MainMenu mainMenu1;
		static public localhost.Service1 ws = new localhost.Service1();
		private System.Windows.Forms.Button button1;
		private System.Windows.Forms.TextBox AdressField;
		private System.Windows.Forms.Label linkStatus;
		private System.Windows.Forms.Panel panel1;
		
		bool start = false;

		public Form1()
		{
			//
			// Required for Windows Form Designer support
			//
			InitializeComponent();

			//
			// TODO: Add any constructor code after InitializeComponent call
			//
		}
		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		protected override void Dispose( bool disposing )
		{
			base.Dispose( disposing );
		}
		#region Windows Form Designer generated code
		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
		{
			this.mainMenu1 = new System.Windows.Forms.MainMenu();
			this.AdressField = new System.Windows.Forms.TextBox();
			this.label1 = new System.Windows.Forms.Label();
			this.timer1 = new System.Windows.Forms.Timer();
			this.button1 = new System.Windows.Forms.Button();
			this.linkStatus = new System.Windows.Forms.Label();
			this.panel1 = new System.Windows.Forms.Panel();
			// 
			// AdressField
			// 
			this.AdressField.Location = new System.Drawing.Point(72, 16);
			this.AdressField.Size = new System.Drawing.Size(160, 20);
			this.AdressField.Text = "http://laptop/Service1/";
			this.AdressField.TextChanged += new System.EventHandler(this.AdressField_TextChanged);
			// 
			// label1
			// 
			this.label1.Location = new System.Drawing.Point(8, 16);
			this.label1.Size = new System.Drawing.Size(64, 20);
			this.label1.Text = "Service url:";
			// 
			// timer1
			// 
			this.timer1.Enabled = true;
			this.timer1.Interval = 10000;
			this.timer1.Tick += new System.EventHandler(this.timer1_Tick);
			// 
			// button1
			// 
			this.button1.Location = new System.Drawing.Point(160, 8);
			this.button1.Text = "ok";
			this.button1.Click += new System.EventHandler(this.button1_Click);
			// 
			// linkStatus
			// 
			this.linkStatus.Location = new System.Drawing.Point(16, 8);
			this.linkStatus.Text = "linkStatus";
			// 
			// panel1
			// 
			this.panel1.BackColor = System.Drawing.Color.RoyalBlue;
			this.panel1.Controls.Add(this.button1);
			this.panel1.Controls.Add(this.linkStatus);
			this.panel1.Location = new System.Drawing.Point(0, 48);
			this.panel1.Size = new System.Drawing.Size(248, 224);
			// 
			// Form1
			// 
			this.Controls.Add(this.panel1);
			this.Controls.Add(this.label1);
			this.Controls.Add(this.AdressField);
			this.Menu = this.mainMenu1;
			this.Text = "Form1";
			this.Load += new System.EventHandler(this.Form1_Load);

		}
		#endregion

		static void Main()

			Application.Run(new Form1());
		}

		private void Form1_Load(object sender, System.EventArgs e)
		{
			//MessageBox.Show( "Filen " + " har laddats ned." , "En utav dina filer har laddats ned." );
		}

		private void timer1_Tick(object sender, System.EventArgs e)
		{
			if( start )
			{
				if( ws.sendMessage( false ) )
				{
					MessageBox.Show( "Filen " + ws.GetFile() + " har laddats ned." , "En utav dina filer har laddats ned." );
				}
				timer1.Interval = 10000;
			}

		}

		private void button1_Click(object sender, System.EventArgs e)
		{
			string url = ws.Url;

			start = true;
			
			ws.Url = AdressField.Text+"Service1.asmx";

			linkStatus.Text = "Link Status: OK";

			ws.methodUrl( ws.Url );
		}

		private void AdressField_TextChanged(object sender, System.EventArgs e)
		{
		
		}
	}
}
