Invoke the node: export image does not work in sub - VI?

Windows 7 64 bit

LabVIEW 9, 32-bit

bug alert!

See example attached vi

The image of export invoke node only work while the Subvi is open, so called as a Subvi and the Subvi is closed this function fails to create an image.

Using the graphical version express XY, I created an xy chart.  Then created an invoke node to export the image of the xy graph.  When I call this vi as a Subvi, it works, as far as the Subvi remains open.  If I close the Subvi and don't run the main vi, no image is created.

No explanation why this would be?  LabVIEW 10 has the same problem?

So the answer is simple, whenever an image is desired from a Subvi always use: invoke the node-> get image, in addition to any collection already implemented code to force labview to update the image

    M175nw printer. email prints from my iphone, but the image does not work

    If the DPI (dots per inch) is less than 100, the printer will not print the photo because it would be too low in quality. Draw the image on the computer, then right-click on it and click Properties, check the horizontal and vertical dpi and see if these figures are less than 100. Have you tried to connect the iPhone to the same network as the printer and try to AirPrint peak? AirPrint road doesn't have the same requirements on IPR as the ePrint.

  • Craigslist 'Reply' and the buttons 'Add images' does not

    Until a few weeks ago, I used Firefox with no problem when browsing and posting Craigslist ads. Recently, the 'Reply' button in the messages does not at all. Nothing happens when I click it.

  • Webcam on the Satellite A200-175 does not work - error code 10

    Hi all

    I bought a Satellite A200-175 yesterday and I am trying to use the webcam, but it does not work. I searched the forum for possible solutions, but so far I have not found anything that solves my situation.
    The laptop came with a preinstalled Vista OS, but the software of the webcam was not preinstalled. So I downloaded the latest Toshiba download page doftware and installed.
    Subsequently, it still does not work and so I changed drivers for generic Microsoft (based on the advice of the forum).

    I tried to reinstall drivers (several times), but that did not help. Device Manager keeps giving me the error code 10 (device cannot be started).

    I'm a bit of idea, so any help would be appreciated!

    Hello Franca

    It's very strange because I installed the recovery image on notebooks P200 and U300 (both with the webcam) and I didn't notice any problem. After the first boot the cam will be recognized as new hardware and installed correctly.

    Changed the product forum this thread is in Thunderbird in Firefox so no need to create a duplicate thread.

    It is an Extension in Firefox and not a Plugin like Flash or Java.

    You're too test is based on the Beta channel (currently at 37.0b3), and the Extensions like these tends to do not support the current version at most which is Firefox 36. www.mozilla.org/Firefox/All/
