Rashid Umarov :

10 yıl zaten neredeyse yayınlandığı gibi https://www.mql5.com/en/code/8007

mt 5'teki piyasa bilgisi çalışmıyor ...

Dürüst olmak gerekirse kafam karıştı....


 AccountInfoInteger ( ACCOUNT_LOGIN )

terminalin başında 0 veriyor ama hesap numarasını vermesi gerekiyor....

0, terminal zaten ağa bağlı olsa bile birkaç saniye verir...

PlaySound hakkında başka bir soru

indikatörde kullanıyorum.

Melodi 3 saniye çalmalıdır.

OnTimer uygun değil çünkü 3 saniye çok fazla ve daha azsa melodi havlıyor

OnChartEvent çalışmıyor, fare veya klavye tıklaması gerekiyor

Melodi havladığı ve sonuna kadar oynamadığı için OnCalculyate uygun değildir


Bütün uyku şarkısının tuzu hindilerde kullanılamaz...


Uzmanlara soru, PlaySound'un göstergede 2-3 saniyeden fazla çalmasını nasıl sağlar ???

OBJ_CHART nesnesinde komut dosyasını çalıştırın. Böylece en azından göstergede tam bir müzik çalar yapabilirsiniz.

Neye benziyor ? anlamadım...

Derleme hataları

 class A {
public :                          //(*)
static void g1() {}
protected :                       //(**)
static void g2() {}
};
class B : A {};                 //(***)
class C : public B {
public :                         //                Основание:
       void f1() { this .g1(); } //(1) ошибка      ***    препятствуют
static void f2() {   A::g1(); } //(2) ошибка ???  *** не действуют (прямой доступ) +
                                 //                  * не препятствует              +
                                 //                    противоречие с (5)- там нормально
       void f3() { this .g2(); } //(3) ошибка      ***    препятствуют
static void f4() {   A::g2(); } //(4) ошибка ???  *** не действуют (прямой доступ) +
                                 //                 ** не препятствует
};
void OnStart ()
{                               //                Основание:
    A::g1();                     //(5) нормально
    A::g2();                     //(6) ошибка       **    препятствуют
}

(2) ve (5) arasındaki çelişki nedeniyle (2) ve (4) numaralı hatalar gerekçelendirilmez.

  • (2) C::f2'de A::g1'e erişim yok
  • (5) OnStart'ın A::g1'e erişimi vardır

sözdizimi aynı iken. OnStart neden daha iyi?
