repxl:
hello, so i included the #include <stdlib.mqh>
i wanna use the std::map from this tutorial http://thispointer.com/stdmap-tutorial-part-1-usage-detail-with-examples/
Have you bothered to look what is in stdlib.mqh? #import "stdlib.ex4" string ErrorDescription(int error_code); int RGB(int red_value,int green_value,int blue_value); bool CompareDoubles(double number1,double number2); string DoubleToStrMorePrecision(double number,int precision); string IntegerToHexString(int integer_number);
That's it.Your link points to the C++ standard template library. The is MQL4 not C++ There is no STD:: anything. //| Mql4 is like C++ except: no typedefs or namespaces, no pointers | //| to POD (so no iterators,) no operator(), operator*, or | //| operator-> (latter two are unnecessary as pointers are | //| automatically dereferenced when used.) No implicit conversions | //| (operator bool), no Koenig lookup, can't return references, no | //| dynamic cast (yet build 950,) no exceptions, no class friends, no| //| multiple inheritance. No stand alone operatorXX() functions (yet | //| build 950.) Can't use template<class X...> must be template | //| <typename x...>. Given a f(const T&){} f(123) or f(f2()) doesn't | //| compile (Build 950,) must have a actual variable - this means | //| templates can not deduce their data types for temporary | //| variables. Structures must be passed by reference. |
