Тема: AHK: AHK_H V2 вызов класса из Base64.ahk
Здравствуйте!
Понимаю что возможно не каждый изучает AHK_H v2, но возможно кто-то сможет помочь с проблемой.
Нашел данный код для AHK_H v2: Base64.ahk.
Однако там не приведён пример того, как использовать это.
Пытался везде гуглить, но без результатно, а предоставленный chm(документация) файл я не понимаю.
Может ли кто помочь с этим?
Хотелось бы для примера закодировать строчку "Hello World".
UPD: Проблема решена примером ниже.
