Send Ctrl Alt Del in VB6 with SendMessage

I need code in VB6 to send Control-Alt-Delete to my computer but I do not want to use SendKeys. I want to do it by SendMessage or PostMessage API. I had found some code for this but did not know the key values to send. It needs to send each of the keys as well as key up for each one at the end. I need this for XP and Vista. I can test on Vista here. I just know SendKeys is not supported on all Vista machines and its just not reliable enough. I need this asap so please only bid if you can basically do it now. Test first to make sure you know to do this. It should be very easy for someone.
