Hey! i made this .NET remote administration tool for education and purposes only. Maybe some of you people want to buy the code.

Its fresh code. has no any user / owner out of me and made 2 days ago.

I will provide whole source code.

The price will be quite reasonable and cheap. I don't know how to sell it on this platform, but if anyone is interested, they can contact me.

Details:

## Requirements

- Windows 10/11 (x64)

- Visual Studio 2022 recommended

## Quick Start

### 1. Open Solution
Open `r4sovnc.sln` in Visual Studio 2022.

### 2. Build & Run Server
Set `R4SoVNC.Server` as startup project and run (F5).

### 3. Configure Server
- Enter a port number (default: 7890)
- Click ▶ Start Server

### 4. Build a Client
- Click Client Builder
- Enter your server's IP/hostname and port
- Enter output filename (e.g. `r4client.exe`)
- Click Build Client
- Distribute the built EXE to the target machine

### 5. Connect
- When a client runs and connects, it appears in the Connected Clients list
- Double-click a client or select it and click Connect / View
- In the viewer, click Start Control to take control
- Click File Manager to browse and transfer files

## Packet Protocol

| Type | ID | Description |
|------|----|-------------|
| Heartbeat | 0x01 | Keep-alive |
| ScreenData | 0x02 | JPEG frame |
| MouseMove | 0x03 | x, y coordinates |
| MouseClick | 0x04 | button, x, y, down |
| MouseScroll | 0x05 | scroll delta |
| KeyDown/Up | 0x06/07 | VK code |
| FileListRequest | 0x08 | path string |
| FileListResponse | 0x09 | JSON array |
| FileUpload | 0x0A-0C | request, data, complete |
| FileDownload | 0x0D-0F | request, data, done |
| ClientInfo | 0x10 | machine name |
| Disconnect | 0x11 | graceful disconnect |

## File Transfer Usage

1. Click File Manager in the viewer toolbar
2. Left panel = your local files | Right panel = remote client files
3. Upload: Select a local file → click ⬆ Upload → (or drag from local to remote)
4. Download: Select a remote file → click ⬇ Download ← (or double-click)
5. Navigate folders by double-clicking directories
6. Use ↑ Up to go to parent directory, ↻ Refresh to reload

## Notes

- For internet connections: use your public IP or a domain name in the builder
- Screen quality can be adjusted in `ScreenCapturer` (default: 50% JPEG quality)
- The client runs silently in the background (console hidden in release builds)
