私はcsvファイルから値を読み取り、それを特定の場所の.cファイルに更新するコンソールアプリケーションを開発しました。私はそれを拡張し、より良いGUIのためのexeファイルを作成する必要があります。しかし、コンソールアプリケーションで動作する同じコードは、Visual Studio 2010のWindowsフォームにエラーを投げています。 getline、eof()、file.openなどのコマンドはエラーを投げています。私はコーディングで初心者であり、どんな種類の助けでも感謝します。Windowsフォームでのexeファイルの生成（C++を使用）

理由標準ライブラリのネイティブC++コードと.NetフレームワークのマネージC++ CLIコードを混在させることです。 1つまたは別のものを使用すると、動作します。 –
あなたは詳細を教えてください...私はいくつかのライブラリを追加するか、マイナーな変更を行うことによって、Windowsフォームで動作するネイティブC++コードを作成できますか？ –
ここではコンパイラのエラーを質問に表示して、人々が簡単に役立つようにしてください。 –
