webcam resolution problems with USB IMAQ

[bartS]

Hi. I’ve a problem with a Webcam. I’ve a USB webcam and I use LabView, Vision and NI_IMAQ_for_USB.zip to setup and control the webcam.

When my Labview  program starts it selects the webcam, and asks me for the resolution through a window generated by the own device drivers.

I don’t want this operation as a default, but I want to automatically set the resolution of webcam as 640x480 automatically via LabVIEW..

Some help?

Avoid the second VI (Imaq Usb propertypage). In the first one (Imaq Usb Init) there's a parameter that is the index to the video modes supported by your camera. Try different values and you will see it.
