# Connect to Server from Diarkis Client

## Introduction

This page explains how to connect to and communicate with a Diarkis server, started using the "Starting a Diarkis Server Locally" guide, using the C++ `room_broadcast` sample. In the `room_broadcast` sample, a virtual room is created on the Diarkis server using the Room module, allowing two users to connect and exchange data with each other. For a detailed explanation of the sample, please refer to [room\_broadcast](https://help.diarkis.io/en/diarkis-modules/room/sample/room-broadcast).

## Windows Environment

1. Open `samples/room_broadcast/win-x64/room_broadcast.sln` in Visual Studio.
2. Specify the command arguments under Project > Properties > Debugging.

   ```
    $(endPoint) $(uid) $(clientKey) 
    Example: 127.0.0.1:7000 1111 AAAA
   ```
3. Build and launch the program with F5. Once the sample program starts, and upon connecting to the Diarkis server, the following log will be displayed:

   ```
   Start
   FileLoggerBackend created files ./logs/1111/diarkis-log.log
   ============================
   Loop=1
   Endpoint: 127.0.0.1:7100
   UID     : 1111

   Connecting to the UDP server...
   Connected
   Joining a room...
   Joined
   Room members: 1111
   ```

   The `room_broadcast` sample waits for multiple users to connect to the room before proceeding with the sample processes. If only one user connects, the program will wait for other users to connect.
4. Run multiple clients as separate processes from a Windows terminal (command prompt), etc. The executable is output to `samples/room_broadcast/win-x64/x64/Debug/bin/room_broadcast.exe`.

   ```
   > ./x64/Debug/bin/room_broadcast.exe $(endPoint) $(uid) $(clientKey)
   Example: room_broadcast.exe 127.0.0.1:7000 2222 BBBB
   ```

   When two users connect to the Diarkis server, the following log is displayed, confirming that data transfer through the Room module of the Diarkis server is taking place.

   ```
   Connecting to the UDP server...
   Connected
   Joining a room...
   Joined
   Room members: 1111, 2222
