I have a question about setting an icon for a plugin button.

[hktkzyz]

CorelDraw X7 64-bit, Visual Studio 2019.

I want to set an icon for a plugin button (not a form, it's the icon for "AddCustomButton").
I have only managed to do these two ways:

1. Use a local file path with SetCustomIcon:
   _bstr_t bstrPath(m_pApp->Path + _bstr_t("Plugins64\cn_plugin.ico"));
   ctl->SetCustomIcon(bstrPath);

2. Use a GUID:
   ctl->SetIcon2(_bstr_t("guid://d2fdc0d9-09f8-4948-944c-4297395c05b7"));

I have already added my own .ico file to the project resources (IDI_ICON1), and included #include "resource.h" in my cpp file.
But I don’t know how to use it for the button icon.
I see other plugins have their own icons without extra .ico files.
Could you please tell me how to do this?
Thank you very much!

You also may to add controls through xml-files (config.xml and AppUI.xml). It all pretty undocumented. Just see files in SmartDepart and Voronoi repositories. Maybe this page will usefull - https://github.com/Georgy-Garnov/CorelApiMissedDoc.
