Basic sample (.NET)

Overview

This sample demonstrates the basics of the Remoting SDK Server and Client.

Getting Started

• Build and launch the Basic Sample Server. It contains one service with three operations: Sum, GetServerType and EchoTypes.
• Build and launch the Basic Sample Client.
• Choose the variables A and B and click Sum. The Sum result will be shown.
• Click Get Server Time. The corresponding server time will be shown.
• Click Echo Types. Different types of variables will be shown.

Examine the code

The sample shows the basics in working with the Remoting SDK framework.

The server

The server side contains a RODL file with the service BasicService, which allows to summarize two elements, get the server time or get different types of variables. Each operation has its own implementation:

• BasicService_Impl.cs

public virtual int Sum(int A, int B)
{
    return A + B;
}

public virtual System.DateTime GetServerTime()
{
    return DateTime.Now;
}
. . .

The client

The client side represents the Remoting SDK client that contains the message and channel components to create a Remoting SDK proxy service and interface file (BasicLibrary_Intf.cs) with the corresponding proxy class declaration. The client uses a standard mechanism to call service operations:

• ClientForm.cs

//private RemObjects.SDK.WinInetHttpClientChannel clientChannel;
//private RemObjects.SDK.BinMessage clientMessage;
//BasicService = CoBasicService.Create(clientMessage, clientChannel);
private void bSum_Click(object sender, System.EventArgs e)
{
   int result = BasicService.Sum((int)nudA.Value, (int)nudB.Value);
   MessageBox.Show("The server returned " + result.ToString());
}

private void bGetServerTime_Click(object sender, System.EventArgs e)
{
   DateTime result = BasicService.GetServerTime();
   MessageBox.Show("The server time is " + result.ToString());
}
