Loops generally begin with a specific statement describing what type of loop it is. こんにちは、業務自動化ツール開発担当の吉池（@valmore_myoshi）です。, 今回は、VBAにおける繰り返し処理の一つ、Do ~ Loop文を解説します。前回はFor文を取り上げましたが、特定の条件を満たすときに処理を実行し続けるならDo ~ Loop文が適しています。, 本記事では、そんなDo ~ Loop文の基本はもちろん、For文との使い分けまで解説します。ループ処理の扱い方を学んでVBAをより使いこなす一助になれば幸いです。, Do While ~ Loop文とは、条件を満たしていれば繰り返し処理を実行する制御構文です。Do Whileのあとに条件式を記述します。, 例えば、ループ処理のたびに１ずつ加算し、５以上になるまで繰り返すプログラムを考えると、下記のように書けます。, Do While ~ Loopの繰り返し途中でループを飛ばしたいときは一工夫必要です。ほかのプログラミング言語を学んだことがある方はContinueを使えばいいのでは？と思うかもしれませんが、VBAにContinueはありません。, そのため、If文を使って処理を飛ばす処理を書きましょう。下記の例ではカウント数が３のときに処理を飛ばしています。, また、ループを抜けたいときはExit Doを使います。下記の例はループ処理のたびに変数に１を加算し、３になったときにループを抜けるよう処理しています。, 繰り返し処理の基本であるFor文では、ループ回数を指定したり、For Each文で配列やコレクションの要素数分のみループ処理できました。一方、Do While ~ Loop文であれば回数がわからなくても柔軟に対応できます。, 例えば、ループ回数を指定せずとも、セルに値が入っている間は処理を行う、ということがDo While ~ Loop文ではできるのです。下記の例は、指定した列のセルに値が入っている間、となりのセルにカウントした数を入れるプログラムです。, つまり、回数を明示的に指定したい、あるいは配列やコレクションの全要素を対象にループ処理するときはFor文がオススメ！逆に回数がわからなかったり、回数に依存しない条件に応じてループさせたいときはDo While ~ Loop文が適しています。, For文について詳しく知りたい方は下記の記事をご覧ください。【Excel VBA入門】For文の使い方。繰り返し処理の基本を学ぶ, Whileの代わりにUntilを使えば条件を満たさなければループを続行する処理を書けます。, 先ほどの例題である、セルの値が入っていればとなりのセルにカウント数を代入するプログラムをUntilで書き直してみましょう。Whileでは「セルの値が空でない」が条件でしたが、Untilでは「セルの値が空である」を条件にすると同じ意味合いになります。, これまでのDo While ~ Loop文では最初に条件式を判定するため、条件を満たさなければ一度もループ処理をせずに終了するケースもあります。, しかし、最初の１回は必ず処理させたいときもあるはずです。そんなときは最初にWhileを付けるのではなく、Loopの後にもっていきます。Whileの代わりにUntilも同様に使えます。, 例えば、１から10のランダムな数を計算して、５が出るまで繰り返す処理は下記のように書けます。算出した値が５でない限りループ処理を実行するようにしています。, 条件を満たしている限りループし続けるDo ~ Loop文を解説しました。繰り返し処理を書きたいけど、ループ回数がわからないときにオススメです。, For文と合わせてDo ~ Loop文も使いこなせるようになれば、繰り返し処理は完璧！書き方を覚えるだけなので、しっかりマスターしましょう。, 【Excel VBA入門】Select Case文の使い方。複数条件をスッキリ書く！, 【完全初心者向け】Python入門その3-プログラムを書いてみよう(Windows10編)-, 【完全初心者向け】Python入門その１-プログラムって？Pythonがおすすめの理由-, 【Excel VBA入門】Dictionaryとは？データ管理が楽になる連想配列の作り方, 【Excel VBA入門】ドロップダウンリストの作り方。複数リストの連動方法も解説.
