UpdateFrame на нескольких формах

Я создал интерфейс Cine Brain-Computer в C#, на каждой из форм есть мерцающие изображения. Однако это только в основной форме, где происходит мерцание. Кто-нибудь знает, как заставить updateframe работать и с другими формами?UpdateFrame на нескольких формах

       this.Hide(); 
       //udpSock2.Close(); 
      } 
      else if (numVal == 55) 
      { 
       //button1.PerformClick(); 
       this.Hide(); 
       //udpSock2.Close(); 
      } 
     } 
    } 
}

У меня 7 форм, которые должны быть в состоянии открыть и скрыть после выбора символ внутри формы.

что произойдет, если вы отмените комментарий закомментированные линии? un-comment all, кроме Application.Run (form); линии - должна быть только одна такая строка - вам нужно показывать другие формы в другом месте. – JinJi

@JinJi, Если у меня есть, как сейчас, формы открываются, если мерцание не происходит, если я раскомментирую строки, соединение udp заставляет программу сбой. –

Теперь я очищаю код, когда он смотрит на данный момент (Program.cs), и только один 'Application.Run (form);' –

попробовать так:

public static ABCDE form; 
    public static BCI1 form1; 

    [STAThread] 
    static void Main() 
    { 
     Application.EnableVisualStyles(); 
     Application.SetCompatibleTextRenderingDefault(false); 
     form = new ABCDE(); 
     form1 = new BCI1(); 
     form.Show(); 
     form1.Show(); 
     Application.Idle += new EventHandler(Application_Idle); 
     Application.Run(); 
    } 

    static void Application_Idle(object sender, EventArgs e) 
    { 
     Message message; 
     while (!PeekMessage(out message, IntPtr.Zero, 0, 0, 0)) 
     { 
      form.UpdateFrame(); 
      form1.UpdateFrame(); 
     } 
    }

, чтобы установить его на зеленый:

long timeToBeGreenInMiliseconds = 10; 
long timeWhenValue83WasSent; 
bool shouldBeGreen; 

void CallThisFunctionWhenValue83IsSent() 
{ 
    timeWhenValue83WasSent = stopwatch.ElapsedMilliseconds; 
    shouldBeGreen = true; 
} 

public void UpdateFrame() 
{ 
    if(shouldBeGreen) 
    { 
     pictureBox1.BackColor = Color.Green; 
     if(stopwatch.ElapsedMilliseconds - timeWhenValue83WasSent > timeToBeGreenInMiliseconds) 
     { 
      shouldBeGreen = false; 
     } 
    } 
    else 
    { 
     double cycleHz1 = 0.006; 

     double wave1 = Math.Sin((stopwatch.ElapsedMilliseconds * 2.0 * Math.PI) * cycleHz1); 

     if (wave1 > 0.0) 
     { 
      pictureBox1.BackColor = Color.Black; 
     } 
     else 
     { 
      pictureBox1.BackColor = Color.White; 
     } 
    } 
}

. Это делает проблескивание. Но что, если мне хотелось бы показать форму, а form1 будет отображаться только тогда, когда я этого захочу?, Сообщение об ошибке соединения udp из-за того же номера порта, это я пришел, закрыв и открыв udp вдоль форм , –

move "form1.Show();" туда, где вы этого хотите. use "form.Hide();" чтобы скрыть форму. если вы хотите сделать это в других классах, вы можете использовать: Program.form1.Show(); и Program.form.Hide(); потому что программа является статическим классом – JinJi

Вы думаете о том, как сделать BackColor зеленым в течение небольшого периода времени, когда выбран объект? Я пытаюсь в данный момент, но кажется, что UpdateFrame отменяет мою попытку использовать pictureBox1.BackColor = Color.Green, если значение, отправленное UDP, равно 83. @ JinJi –

UpdateFrame на нескольких формах
