System-Warning

⚡ Prank App – System Warning Demo

A fun and visually dynamic Python Tkinter application that simulates a system warning screen with flashing borders, progress effects, speech, and sound.
Created by Md Anayet Hossen as a learning and demonstration project for Tkinter UI, threading, and audio handling in Python.

🚀 Features

Fullscreen GUI with animated flashing border
Color-changing warning icon (rainbow cycle)
Real-time progress simulation with emoji
Voice announcements using pyttsx3
Beep sound effects using winsound
Multithreaded design for smooth animation
Safe exit shortcut (Ctrl + 0)

🧠 Learning Goals

This project demonstrates:

Tkinter GUI layout & styling
Python multithreading
Sound handling in Windows
Text-to-speech integration
Event binding and UI control

⚠️ Disclaimer

This app is for educational and entertainment purposes only.
It does not actually hack, copy, or access any real data.
Please use responsibly and do not distribute it to mislead others.

🛠️ Requirements

Install dependencies before running:

pip install pyttsx3

(winsound is built-in on Windows)

▶️ How to Run

Download or clone this repository
Open a terminal in the project directory
Run the script:

python "System-Warning.py"

To safely exit the demo, press:
```
Ctrl + 0
```

🗜️ Convert Python Script to Windows `.exe`

Nice — converting a Python script into a Windows .exe is straightforward.
The most common tool is PyInstaller.
Below are concise, copy-pasteable commands for both Command Prompt (cmd) and PowerShell, plus helpful tips and common gotchas.

⚡ Quick Steps (Recommended)

Open cmd or PowerShell.
(Optional but recommended) Create & activate a virtual environment.
Install PyInstaller:
```
pip install pyinstaller
```
Build the .exe with PyInstaller.
Find your executable inside the dist\ folder.

🧩 Example — Basic Console Program

Assume your script is System-Warning.py.

Command Prompt:

python -m pip install --upgrade pip
python -m pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

PowerShell:

python -m pip install --upgrade pip
python -m pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

After this, the executable will be at:

dist\System-Warning.exe

⚙️ Common Useful PyInstaller Options

Option	Description
`--onefile`	Bundle into a single `.exe` (recommended for distribution)
`--windowed` / `--noconsole`	For GUI apps (no console window)
`--icon=app.ico`	Attach an icon (use `.ico` format)
`--add-data "src;dest"`	Include data files (use `;` on Windows)
`--hidden-import modulename`	Fix missing imports
`--clean`	Remove temporary build files before building
`--noconfirm`	Overwrite previous builds without asking

Example with icon:

python -m PyInstaller --onefile --windowed --icon="C:\path\to\app.ico" "System-Warning.py"

PowerShell note for --add-data quoting:

python -m PyInstaller --onefile --add-data 'C:\path\to\data\myfile.dat;data' "System-Warning.py"

💡 For Apps Using Tkinter, PyQt, pandas, numpy, etc.

PyInstaller usually detects these automatically.
If not, add manual hints:

python -m PyInstaller --onefile --hidden-import=some_module "System-Warning.py"

For data files, use:

python -m PyInstaller --onefile --add-data "assets;assets" "System-Warning.py"

🧰 Creating & Using a Virtual Environment (Recommended)

Command Prompt:

python -m venv venv
venv\Scripts\activate
pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

PowerShell:

python -m venv venv
.\venv\Scripts\Activate.ps1
pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

If activation is blocked:

Set-ExecutionPolicy RemoteSigned

(Run as Administrator and understand the implications before changing execution policy.)

📦 Where to Find the Built `.exe`

After running PyInstaller:

✅ dist\System-Warning.exe — final executable
🧩 build\... — build intermediates
⚙️ System-Warning.spec — configuration file (editable for advanced builds)

To clean up:

rmdir /s /q build dist
del System-Warning.spec

🧪 Testing and Distribution

Test the .exe on a machine without Python installed
Some antivirus software may flag unsigned executables
Code sign your exe if you plan broad distribution
Single-file .exes are larger because they bundle the Python runtime

🧯 Troubleshooting

If your exe crashes, rebuild without --windowed to see the error:
```
python -m PyInstaller --onefile "System-Warning.py"
```
Run from CMD to read any error messages.
Check missing resources (--add-data) or hidden imports.

🔄 Alternatives

Other tools exist (like cx_Freeze, py2exe),
but PyInstaller remains the most popular and simplest for most needs.
