enum GuiEventType
{
    Exception,
    ClickOnElement,
    TextChange,
    ScrollChange
};

adding the above in the mql5 file works.

[hini]

MtGuiController::ClickOnElement

It should be used like this and does not need to be defined in mql5

In your article there is the following sentence:

"Like any technology, the proposed approach has its drawbacks. The main one is the impossibility of working in the Market, since calling third-party DLLs is prohibited"

What does this mean? Will I not be able to press the Buy/Sell button on the Winform to buy/sell on a real account?
