First, if your using Windows NT, it will be very hard to get USB to work.
What we've done to get an image in LabVIEW, is this. We've made the PC a
webserver. We've used third party software to build a webpage with the
"webcam". We've used ActiveX to show the webpage in LabVIEW.
Another way is: Use third party software to constantly update a .jpg. In
LabVIEW, check if the jpg is modified, load it, and display it. You'll get
some heavy 'flickering' this way.
I've look at a way to use window API's to capture the image, but it isn't as
easy as it sounds.

I'd like to use a cheap web camera as
an input device to Labview so that
I can play with the image processing features.
Does anyone have a driver for something like that? I've looked at the
NI web site and I haven't found anything for USB. Lots of firewire, IEEE
1394,
but no USB.
