Simple tutorials and practical guides

This site is built for anyone who needs to finish a task, see where the code goes, and move on without digging through messy notes.

The text is short on purpose. Most pages tell you what file to create, what to paste, and what quick test to run.

Search first

Use the search bar at the top to jump straight to a topic like median, Form1, or slider.

Copy by file

Console tasks use Program.cs. Browser tasks are split into index.html, style.css, and script.js.

Keep it small

Most tasks here are starter-sized so they are easy to rebuild, test, and reuse.

Workflow

Fastest way to use one tutorial

1

Open the matching track

Choose C# Console, C# Forms, Flowcharts, HTML/CSS/JS, or Tinkercad.

2

Read the build steps first

Do not copy code before you know which file or control names the task expects.

3

Paste one file at a time

Console tasks go into Program.cs. Browser tasks are split into files. Forms tasks tell you which file and which controls to make.

4

Run the quick test

Each page gives a small check so you can see right away if your version works.

Use cases

Common things people look for

I need one small C# task

Start on C# Console. Most examples use one file and are easy to edit.

I need a button-click form

Go to C# Forms. The controls and file placement are written out.

I need a working web page

Open HTML/CSS/JS for copy-ready browser examples.

I need algorithm blocks

Use Flowcharts if the task is about logic, loops, or decisions.

I need an Arduino demo

Open Tinkercad and start from the screenshot.

I need a server or admin guide

Open IKT Admin for Office 365, Group Policy, Samba, SSH, Apache and Mikrotik.
