In Response to: "Anyone know how to access the settings in the property page for the USB webcam driver by LabVIEW 6.1i. I want to sets the values of the camera source programatically."
First of all, the requirements fot the USB webcam driver states that you need: LabVIEW 7.0 or higher with NI Vision 7.1 or higher for the USB LabVIEW support. This can be found on the following link: http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=ED6942DF78E34659E034080020E74861. So this specific driver probably will not work well with LabVIEW 6.1, because it it intended for LabVIEW 7.0 or higher. Also, the NI-IMAQ for USB Cameras driver is not officially supported by National Instruments. Also, check out the KB named "Acquiring Images in LabVIEW Using a USB Camera", and this will also help answer some other questions you might have about the driver, or these documents.
Now if you have the driver and it is working, it comes with a great example program, Grab with Property Page.VI, which allows you to access the camera manufacturer's configurations. The specific VI that does this, via accessing DLL's, is the IMAQ USB Property Page.VI.
I hope this helps. Please let me know if you have any questions, or need any clarification. Thanks, and have a great day.
