Hey there! Let's break this down clearly since you're just starting out with programming—no worries about any imprecise questions, we've all been there.

First, a critical distinction to make: Redmine is a web application built with Ruby on Rails, which works entirely differently from Windows Forms (a desktop .NET framework). That means you can't drag-and-drop buttons or controls onto forms like you do in Visual Studio for WinForms. But don't worry—you can still customize the task creation form, and here's how to go about it:

Recommended Approach: Build a Redmine Plugin #

Redmine is designed to be extendable via plugins, which is the safest way to make changes (modifying Redmine's core code directly will break when you update Redmine later). Here's a simplified breakdown for beginners:

• Learn basic Ruby & Ruby on Rails: Since Redmine is built on these tools, you'll need a foundational understanding to work with its codebase. Start with Ruby syntax, then learn how Rails handles views (the UI part) and controllers (the backend logic).
• Set up a plugin structure: Redmine has a standard folder structure for plugins. You'll create folders for views, controllers, and assets (CSS/JS) specific to your customizations.
• Customize the task creation form:
  • The task creation form lives in Redmine's view files (typically app/views/issues/new.html.erb or related partial files). In your plugin, you can override this view to add buttons, tab bars, or other elements.
  • For example, to add a simple frontend button to the form, you'd add this code in your overridden view:

    <button type="button" class="btn btn-secondary" onclick="showCustomMessage()">My Custom Button</button>
    <script>
      function showCustomMessage() {
        alert('Custom button clicked!');
      }
    </script>
    

  • If you need backend logic (like saving extra data when the button is clicked), you'll add a controller action in your plugin and link the button to it using a form submission or AJAX request.
• Test your plugin: Install it in your local Redmine instance to see the changes take effect.

About Visual Studio 2015 #

VS2015 is optimized for .NET development and doesn't have strong support for Ruby or Ruby on Rails. You'll have a much smoother experience using tools like:

• RubyMine (built specifically for Ruby/RoR development)
• Visual Studio Code (with Ruby/RoR extensions installed)
• Sublime Text or Atom (with Ruby plugins)

Quick Tip for New Developers #

Take it slow: start with small, simple changes (like adding a basic button) to build confidence. Redmine's official documentation has detailed guides on plugin development that walk you through each step.
