■使用ソフト
・Visual Studio Community 2019
■言語
・C/C++
■Windows SDK バージョン
・10.0.17763.0
※Windows SDK バージョンの変更方法
■手順
１．基本的には以下の流れ参照
【C++】 DirectX11 - Direct2D 1.1の初期化（ComPtr使用） //これをベースにコードを変更する
【C++】 メッセージボックスの作成 //プロジェクトの作成からビルドまでの操作方法について
２．以下の4つのファイルを作成してビルドを行う。
（１）Main.h
（２）Main.cpp
（３）DirectX.h
（４）DirectX.cpp
