🎬 YouTube Stream Script (New Year’s Card Creation App Development - Part 1)

Start of the Stream (Opening 2-3 minutes)

Brief Greeting

“Hello. Starting today, I’ll be streaming the step-by-step development of a New Year’s card creation app in C++.” “I don’t know how many streams it will take to complete, but I’ll proceed little by little as a series.” “I’ll basically be working in silence, so I hope you can watch it as background music for your own work.”

Overview of the Target App

“In this app, I’d like to make it possible to design the back side of a New Year’s card.” “I plan to incorporate photo insertion, font arrangement, image processing and illustration generation using AI, and ultimately upload it to the Microsoft Store.”

Today’s Work Goals

“Today, in the first session, we will set up the environment and build the foundation.” “Specifically, I would like to proceed with:

Creating a GIT repository
Creating the main window
Displaying the version information dialog
Creating menus and implementing the exit command
Direct2D initialization/release processing and displaying HelloWorld”

Regarding the Source Code Release

“The source code is published on GitHub. If you are interested, please take a look.” → https://github.com/kenjinote/NengaCardApp/

Working Part (Silent)

Create GitHub repository → Initial commit

Create the skeleton of the main window

Create version dialog, menus, and implement the exit command

Direct2D initialization and release processing → Confirm HelloWorld display

Push to GitHub as appropriate

Basically silent, add short explanations only when necessary

Before Ending the Stream (Last 1-2 minutes)

Summary of Today’s Progress

“Today, we created the GIT repository and implemented the window, exit button, and version dialog.” “We were able to get to the point of displaying HelloWorld with Direct2D.”

Connection to Next Time

“From next time, I’d like to proceed with organizing the UI part and objectifying strings.”
