или
_asm{ mov eax,1 push eax dec eax push eax call dword ptr[pRegisterServiceProcess] }
А теперь более подробно. Невидимость по Alt-Tab:
var WnHnd : Integer; WnHnd := GetWindowLong(Application.Handle, GWL_EXSTYLE); WnHnd := WnHnd or WS_EX_TOOLWINDOW; {Типа Tools-окно} SetWindowLong(Application.Handle, GWL_EXSTYLE, WnHnd);
Невидимость в Панели Задач:
ShowWindow[Async](Application.Handle,SW_HIDE)
