    <p>I have simple chat program using WCF service. One service use for server and another use for client. Those services connect to each other and call each other. For hosting server, I used a windows service and for client I host WCF service in a Windows app. After all I found that this code work on simple computer, but when move server service to another computer an exception raised and server can't connect to the client. I searched and try other ways. I get a result: *IF WCF SERVICE HOST IN WINDOWS APP U CAN'T CONNECT TO IT FORM ANOTHER COMPUTER. *THIS CODE WORKED ONLY WHEN I USED TWO WINDOWS SERVICES (hosting WCF client service in a windows service) But I want to know HOW hosting WCF service in windows app that can connect and work with another services? This is my code Client code: Manager.cs</p> <pre><code>public delegate void UserInfoHandeler(string UserName); public delegate void MessageHandeler(string Message); [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] public class Manager : IClientPoint { public void SendUserList(string[] users) { frmRoom.Members = users; // this method called by Server (WCF service which host in windows service) //when server call this method I have an exception with SSPI } public void SendMessage(string message) { frmRoom.ReciveMessage = message; // this method called by Server (WCF service which host in windows service) //when server call this method I have an exception with SSPI } FrmJoin frmJoin; FrmRoom frmRoom; ChatServerClient ServiceInvoker; public string User { get; set; } public void Run() { frmJoin = new FrmJoin(); frmJoin.LoginEvent += new UserInfoHandeler(frmJoin_LoginEvent); ServiceInvoker = new ChatServerClient("WSHttpBinding_ChatServer", Settings.Default.ChatServerAddress); frmJoin.ShowDialog(); } void frmJoin_LoginEvent(string UserName) { frmRoom = new FrmRoom(); frmRoom.SendMessageEvent += new MessageHandeler(frmRoom_SendMessageEvent); frmJoin.LogoutEvent += new UserInfoHandeler(frmJoin_LogoutEvent); User = UserName; frmRoom.ReciveMessage = ServiceInvoker.Login(User, Settings.Default.ClientPointAddress); frmRoom.ShowDialog(); } void frmJoin_LogoutEvent(string UserName) { string message = ServiceInvoker.Logout(UserName, Settings.Default.ChatServerAddress); } void frmRoom_SendMessageEvent(string Message) { ServiceInvoker.SendMessage(User, Message); } } </code></pre> <p>Client config:</p> <pre><code>&lt;system.serviceModel&gt; &lt;bindings&gt; &lt;wsHttpBinding&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
