Вот код service1. При вызове открывается блокнот (то же и с моей формой) в task manager на закладке process.
В этом случае, при запуске формы из сервиса, я вижу процесс в task manager на закладке процессы, который я запустил. Но на закладке application его нет.

Как мне запустить форму из сервиса, чтобы она появилась на закладке application? Я думаю, что именно в этом причина, что моя форма не работает как должна. |
