A compact reference addressing the points raised by and building on 's replies.

Closing forms vs process lifetime

  • Closing all visible forms does not always end the process. WinForms apps run a message loop; background threads or non-background threads keep the process alive. Use form.Close() for individual windows and Application.Exit() for a polite shutdown. To force termination use Environment.Exit(0), but prefer graceful shutdown when possible.

Running at startup (alternatives)

  • Besides putting a shortcut in the Start Menu (as noted), more robust options are: create a Windows Service (for true background tasks, needs admin), register a scheduled task (Task Scheduler) to run at logon, or add an autorun entry under the Run registry key. Each approach has trade-offs (permissions, visibility, and how Windows treats the program) and may trigger security warnings if abused.

Webcam, chat, RTF and remote text

  • USB webcams are accessed like any video capture device. Use DirectShow or Media Foundation, or higher-level libraries such as AForge.NET / Accord.NET / OpenCV wrappers for capture and frame processing.
  • For chat: LAN-only simple solutions can use UDP broadcast. For Internet P2P, NAT traversal is required (STUN/TURN/ICE) or use WebRTC; otherwise a server for signaling is needed.
  • RichTextBox image insertion commonly uses the clipboard: put an Image on the clipboard and call richTextBox.Paste(). To load text from the web, download the content (e.g., WebClient.DownloadString) and set richTextBox.Text. If the remote data is RTF, load it into a stream and call richTextBox.LoadFile(stream, RichTextBoxStreamType.RichText).

IP addresses

  • Local IPs: use Dns.GetHostEntry(Dns.GetHostName()).AddressList and filter for IPv4. Public IP requires contacting a remote "what is my IP" service over HTTPS.

Blocking input / hiding processes — caution

  • Intentionally hiding processes or blocking keyboard/mouse is frequently malicious and will trigger antivirus/forensic detection. For legitimate kiosk scenarios use Assigned Access / kiosk mode, services, or policy controls. Do not attempt kernel tricks or stealth techniques; they are unsafe and inappropriate.
