Hi GraceSum
Thera have been many posts about the subject. Please, go to head of page and search webcam in discusion forums.
You will find more than 100 posts with url and references about software to use a usb webcam in Labview.
I personally, prefer USB webcam software from NI ( downloadable in this site) bur you need IMAQ vision 7.1.
Hope it helps
