keybd_event
<p>I need the key code for <code>ctrl+alt+del</code> in c#,
for example </p>

<pre><code>const int KEYEVENTF_KEYUP = 0x2;
const int KEYEVENTF_KEYDOWN = 0x0;   
keybd_event(0x11, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(0x41, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(0x11, 0, KEYEVENTF_KEYUP, 0); 
keybd_event(0x41, 0, KEYEVENTF_KEYUP, 0);
</code></pre>

<p>this is the code for <code>ctrl+a</code>.</p>
