  Take a webcam photo on login using Windows 7 http://superuser.com/questions/311569/take-a-webcam-photo-on-login-using-windows-7 The AutoIt program you need can be found here: http://autoitscript.com/forum/files/file/100-welcome-to-autoit-1-2-3/ You will need to get the Webcam.au3 include file from here: http://www.autoitscript.com/forum/topic/68866-webcam-udf/page__p__505896#entry505896 Put it in the same directory as the script or into the autoit include folder. Note the necessary changes in the script. This code will take the snapshot, just run it on startup (just use a shortcut unless you change the save path and use the include folder for the include file). Note that this will flash any LED on the camera on for a half second while it takes the snapshot, there isn't a way around that: #include <GUIConstants.au3> #include <WindowsConstants.au3> #include <Webcam.au3> $gui = GUICreate("Webcam UDF Test",640,480) _WebcamInit() _Webcam($gui,640,480,0,0) GUISetState(@SW_HIDE) Sleep(100) ConsoleWrite("Taking snapshot ..." & @CRLF) _WebcamSnapShot() ConsoleWrite("Snapshot taken !" & @CRLF) While 1 $msg = GUIGetMsg() If $msg = $GUI_EVENT_CLOSE Then _WebcamStop() Exit EndIf Sleep(10) _WebcamStop() Exit WEnd
