Witam,
Piszę program, który pozwala blokować niektóre funkcje Windowsa, np. Regedit, CMD itp.
Oto fragment kodu:
If CheckBox3.Checked = True Then
MessageBox.Show("Zablokowano CMD")
sciezka(1) = "Software\Policies\Microsoft\Windows\System"
klucz(1) = Registry.CurrentUser.OpenSubKey(sciezka(1), True)
klucz(1).SetValue("DisableCMD", 1)
ElseIf CheckBox3.Checked = False Then
sciezka(1) = "Software\Policies\Microsoft\Windows\System"
klucz(1) = Registry.CurrentUser.OpenSubKey(sciezka(1), True)
klucz(1).SetValue("DisableCMD", 0)
End If
Gdy uruchomię program wywala błąd:
System.Security.SecurityException was unhandled
HResult=-2146233078
Message=Żądany dostęp do rejestru jest niedozwolony.
Source=mscorlib

Wydaję mi się, że chodzi o brak uprawnień.
Czy wie ktoś może jak nadać odpowiednie uprawnienia?
