how can I take pictures with a ordinary usb camera and labwindows

hi,

What do you mean "ordinary USB Camera? Is it a Vision Camera with a communication based on the Vision API or a 3rd party camera (like webcam)?

In that last case, you might need to refer to the documentation of the constructor, there should be a library sent with it (C DLL, ActiveX automation, .NET assembly) with functions to communicate with the drivers.

Best regards

If the camera is DirectShow compatible (most generic USB webcams are) you can install the IMAQdx drivers and communicate with the camera that way.  Note that the IMAQdx drivers involve additional licenses from NI for both development and runtime.
