Данный пример покажет полный путь к
исполняемому (exe) файлу.
Расположите на форме элемент CommandButton.
В оригинальном примере в событии Command1_Click()
была лишь одна строчка (та, которая не
закомментирована). Но если вы добавите модуль из
примера "Поиск hwnd
процесса на панели задач", то вы сможете
определить полный путь exe-файла программы ИнтернетЭкспорер.
Не забудьте снять комментарий в событии Command1_Click().
