Multi-Threading Prompts

AI prompts for multi-threading from the LearnWithHasan AI Coding Building Blocks (Performance).

#1 Coding Assistant

Move a Task to Background Thread

Start here. The most common threading fix From the Multi-Threading AI Coding Building Block.

Prompt 
My [desktop app / Electron app / mobile app] freezes when I click the button that [downloads a file / processes images / queries a database / loads data].

Move this task to a background thread so the UI stays responsive. While the task runs:
- Show a loading spinner or progress bar
- Keep all buttons and UI elements clickable
- When the task finishes, update the UI with the results
- If the task fails, show an error message without crashing

My stack: [your language and framework here, e.g. Python + Tkinter, C# + WinForms, Java + Swing, Electron]

I'm learning, so explain each part simply.
#2 Coding Assistant

Add Progress Bar with Background Thread

For tasks where users need to see progress From the Multi-Threading AI Coding Building Block.

Prompt 
I have a long-running task in my [app] that [processes files / converts data / downloads multiple items]. I want to show real-time progress to the user.

Set up a background thread that:
- Runs the task without freezing the UI
- Reports progress back to the main thread (percentage or step count)
- Updates a progress bar smoothly as the task advances
- Allows the user to cancel the task mid-way
- Shows "Done!" when complete and re-enables the start button

Run Multiple Tasks Without Freezing

For apps juggling multiple long operations From the Multi-Threading AI Coding Building Block.

Prompt 
My [app] needs to run several long tasks at once: [list your tasks, e.g. download files + process images + sync data]. Right now they run one after another and the UI freezes the whole time.

Create a system that:
- Runs each task on its own background thread (or uses a thread pool)
- Shows individual status for each task (waiting / running / done)
- Keeps the UI fully responsive throughout
- Updates the screen safely from background threads (no crashes)
- Handles errors in one task without stopping the others
