私のプログラムには、DataGridView
オブジェクト (ボリューム、URL、遅延など) から一連の情報を取得するボタンがあり、それを使用してファイルを再生します。私は遅延を機能させようとしています (再生する前に x 秒待機します)。かなり機能しますが、ボタンを押すたびに再生がすぐに開始されます。遅延の後以外にプログラムのどこにもないCtlcontrols.play()
ので、何が原因で再生されるのかわかりません。
コメントで私の問題をもう少し説明しました。私のコードをうまく説明できていなかったら申し訳ありません。他に何が原因でプレーヤーがすぐに起動するのか教えていただければ、おそらくそれで十分でしょう。
