Block Control+Alt+Delete

Question

I am doing an Online Quiz project in C#. The test client is a Windows Desktop Application running on Windows XP. I need to block the control+alt+d

Answer 1

You'll also want to block alt+F4 with something like this:

private void form_KeyDown(object sender, KeyEventArgs e) {
    if (e.KeyCode == Keys.F4 && e.Modifiers == Keys.Alt)
        e.Handled = true;
    base.OnKeyDown(e);
}
