Since October 2018, MetaTrader 5 supports integration with Net Famework libraries. This set of libraries is actually much more than a framework or a specialized system for performing a specific range of tasks, like drawing graphical windows or implementing a network interaction. Net Framework has literally everything. It allows developing websites (Net Core, MVC), creating system applications having a unified professional interface (Windows Forms), building complex distributed systems with data exchange between nodes and working with databases (Entity Framework). Besides, Net Framework is a huge community of programmers and companies with thousands of various open source projects. If the interaction is organized properly, all this can be available in MQL today.



In this article, we will continue to develop the functionality of GuiController created in the first part. This functionality is aimed at interacting with the graphical functionality of the Net Framework based on the Windows Forms technology. Currently, plenty of info is available on MQL graphical features. There are a lot of various libraries that do more or less the same by means of MQL. Therefore, I do not want this material to be perceived by readers as "another library for working with forms". In fact, this material is only a part of a large series of articles describing interaction with Net Framework and gradually revealing boundless features of this software platform. Windows Forms is only one of the building blocks within this platform, although a very convenient and comprehensive one, just like any part of the Net technology. The Windows Forms graphical subsystem is a great starting point for exploring this framework. After proper studying, it can be applied in other interactions with Net Framework. Besides, it also allows creating quite efficient and, most importantly, easy-to-implement trading panels, EA configuring windows, advanced graphical indicators, robot control systems and other things related to interaction between users and the trading platform.
