Это не исходник, и не DLL. Это офрмленный заголовок исходника DLL, на который потратил больше недели. Написание класса для маппинга заняло неделю. В основном на продумывание структурированности.
А само писание 60 функций заняло 60 минут. Там в каждой функции по паре строчек.
Очень приятная библиотечка. А файлами готовыми Вы не можете поделиться? Или это подразумевает оплату?
Not finished yet. Everything is in process. I am correcting errors in description and editing function names, they are too long for MQL4.
Testing is a long way off. The library is intended to work with my Toolbox and therefore it is protected. I will not give you the source code.
If you want, you may rent it. :-))
But, after all, the most valuable things you have laid out. This description is more important than the source code.
At the moment the header file looks like this:
The header file is now like this:
Файлы придуманы для длительного хранения информации. Зачем терзать диск? Для общения есть ОЗУ.
If you create a disk in RAM (RAMdisk), then the hard drive will not suffer and offer JavaDev makes a certain sense.
And for the library - thank you very much!!! Just a masterpiece!!!
