Error 1074397067: The Requested Acquisition Window is Invalid When Doing a Snap or GrabPrimary Software: LabVIEW Toolkits>>LabVIEW IMAQ Vision for LabVIEWPrimary Software Version: 4.0.1 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I am able to snap and grab in Measurement & Automation Explorer (MAX) without any problems but whenever I snap or grab in LabVIEW I get the following error: Error 1074397067 occurred at IMAQ Snap.vi (or IMAQ Grab.vi) Possible reason(s): NI-IMAQ: The requested acquisition window is invalid.
This error may also occur while using Vision Acquisition Express VI. Solution: LabVIEW usually returns this error because the IMAQ camera initialization requires different acquisition window parameters than the camera file. The following is an example of what has happened (with a FLIR camera): MAX sets a width value of 318. The initialization call in LabVIEW sets the width to 320. Therefore an error that the acquisition window is invalid occurs. There are two possible ways to resolve this:
