次のことについて助けを求めてもいいですか?
GlobalCache GC-100とiTachを介して、3台の家庭用電子機器をコンピューターで接続および制御しようとしています。次のコードでわかるように、機器と通信および制御できるクラス( "GlobalCacheAdapter")を作成し、機器ごとにクラスのインスタンスを作成しました。各インスタンスは、各機器の通信と制御でうまく機能しているように見えますが、*機器から返されたフィードバック*は、定義しているクラスレベルの「ReaderThreadProc」プロシージャでのみ表示されるようです。機器ごとにフィードバックをさらに処理する必要があり、機器固有のインスタンスレベルでこのフィードバックを転送する方法がわかりません。。インスタンス固有のEventHandlerを実装する必要があると思います。ただし、処理を完了して適切なコントロールを更新するために、このタイプのインスタンス固有のEventHandlerを実装する方法についてはわかりません。
どんな助けでも大歓迎です。
