MFC Visual Studio 2013でファイルからビデオを読み込み、オブジェクトを追跡できるプログラムを読みました。私は停止ボタンを設定しました。ビデオの読み込みと読み込みを停止します。私は追跡中の実行中のビデオを停止することはできません。それは私のGUIプログラムです：スレッドでmfcでビデオを停止する

MFCを使いこなすには、C++を初めて使う方が0になる可能性が低くなります。起こることはありません。スレッド間でウィンドウ階層を構築することは、技術的には可能ですが、複雑なので、熟練した開発者であっても、それを防ぐために何かを試すことになります。とにかく、この質問は将来の訪問者に役立つことはまずありません。閉会に投票しました。 – IInspectable
