## Overview

A small Windows Forms utility lets users choose a delay, previews the resulting shutdown time, and schedules or aborts a Windows shutdown. The form code combines timer refresh and command handling; the separate calculation node represents its delay-to-seconds logic. The README is brief, and no additional capabilities are documented.

Main entry points: [`src/shutdown-timer/frmMain.cs`](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/frmMain.cs) (Timer form), [`src/shutdown-timer/frmMain.Designer.cs`](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/frmMain.Designer.cs) (Form controls), [`src/shutdown-timer/Program.cs`](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/Program.cs) (App startup)

## Components

### Desktop app

- [App startup](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/Program.cs): `src/shutdown-timer/Program.cs`
- [Timer form](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/frmMain.cs): `src/shutdown-timer/frmMain.cs`
- [Form controls](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/frmMain.Designer.cs): `src/shutdown-timer/frmMain.Designer.cs`
- [Delay calculation](https://github.com/bariskisir/shutdown-timer/blob/master/src/shutdown-timer/frmMain.cs): `src/shutdown-timer/frmMain.cs`

### System control

- **Windows shutdown**

### Other components

- **User**

## Connections

- App startup → Timer form: runs
- User → Form controls: sets delay
- Form controls → Timer form: dispatches actions
- Timer form → Delay calculation: calculates delay
- Delay calculation → Timer form: returns seconds
- Timer form → Form controls: updates preview
- Timer form → Windows shutdown: schedules or aborts
