New article Applying network functions, or MySQL without DLL: Part I - Connector has been published:

MetaTrader 5 has received network functions recently. This opened up great opportunities for programmers developing products for the Market. Now they can implement things that required dynamic libraries before. In this article, we will consider them using the implementation of the MySQL as an example.

About a year ago, MQL5 network functions were replenished with functions for working with sockets. This opened up great opportunities for programmers developing products for the Market. Now they can implement things that required dynamic libraries before. We will consider one of such examples in this series of two articles. In the first article, I am going to consider the MySQL connector principles, while in the second one, I will develop the simplest applications using the connector, namely the service for collecting properties of signals available in the terminal and the program for viewing their changes over time (see Fig. 1).


The program for viewing changes in signal properties within a certain time

After registering on the website, I tried to run the script with https://dev.mysql.com/doc/index-other.html instead of the IP address, in this case I get.

ERR_NETSOCKET_CANNOT_CONNECT

5272

Ошибка соединения с удаленным хостом

Seems it tries to connect, this I can say due to a bit of delay before I get the error.

You should probably insert the desired IP on the "Allowed servers list".
