Alexandr Bryzgalov:

the reference does not correctly state the order of the parameters.


What is your evidence?

 
Vladimir Karputov:

What is your proof?

Vladimir Karputov:

What is your evidence?

No. There is no mistake.

I was confused by the order itself. And the fact that it doesn't take 0. It always wants a variable.


 
Alexandr Bryzgalov:

No. There is no mistake.

The order itself is confusing. And that it doesn't take 0. It necessarily needs a variable.

That's what it says in the help - it needs a VARIABLE

   int&           sub_window,   // The number of the subwindow
 
Vladimir Karputov:

That's what it says in the fact sheet - VARIABLE is needed

 

Friends, help me out here. I'm completely baffled by what's going on.

Here's the whole indicator. When it starts up, it starts giving

Why such optimism. If I press pause or stop, I still get values in Expert Advisor tab of Toolbox window. The window with the indicator is already closed, but the values are successfully displayed.

How does this happen? Who can explain something?

Who said that CopyBuffer() will be successful at least once?

Who said that iCustom() will be successful?

Since the last update, theEnumToString functiondoes not work correctly depending on the code being called. A separate call toEnum_ does not reproduce the error.

template<typename T>

int Enum_(T enum_value)
  {
   ...
         s1=EnumToString(T(i1));

   ...

   }

In debugger:

GetLastError returns:

ERR_INVALID_PARAMETER.

how did this happen

 
JRandomTrader:

Who says CopyBuffer() will ever succeed?

Who says that iCustom() will be successful?

"Errors can form cycles. The most persistent of these is infinite." Error theory.

The interesting thing is that this function is executed successfully. It is executed and produces values. After that, the terminal only enters an incomprehensible state.

The iCustom() function is executed successfully as well.
