Помогите разобраться с функцие CreateWindowEx()
На её последнем аргументе вылетает ошибка типа
error C2664: 'CreateWindowExA' : cannot convert parameter 3 from 'LPCWSTR' to 'LPCSTR'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Понятно,что надо сделать явное преобразование с помощью reinterpret_cast ,но как именно,пытался,но ничего не получилось...
Код,где возникает ошибка я выделил коричневым цветом...
Подскажите...
