学校の課題の休憩中にWinAPIの練習がてらいつものオセロを作ってみました。
Drawing関数はInvalidateRect()とかでWM_PAINT内で処理させた方がよかったかな。
最初に何よりも迷ったのがVisualC++でのWinプロジェクトの作成。
コンソールだとウィンドウとか出せないので、Winプロジェクトを作る必要があるんだけれど、
わざわざそんな初歩的なこと書いてないし、
なにより参考HPが基本的に以前のVerのVisualStudioだったりとか。
新規プロジェクト→Win32→Win32プロジェクトから作れます。
コンソールアプリケーションじゃだめ。
中身自体は空のプロジェクトでOK。そのあといつものように.cppを追加しとけば大丈夫。
とりあえずAPIの基本的な動き方はわかった（つもり）ので、
これからチェスとか作れればいいなぁなんて。
ちょっと前にもあったけどネタ。
