"NaN" - how to test in VBAI <>- BT?

I use VBAI to measure the length of a line.

I use LabVIEW as the custom interface.

In VBAI, I use "Update of Inspection" to send the data of length to LV

How can I check in vi, that this figure is "NaN? This will happen when the line is not found.

I tried to use ' NaN/path/RefNum"of the LV, but it simply doesn't.

Help please...

I don't know how you test this. I tried it and it works fine. Make sure the update of Inspection stage has the flag to 'Run the VI after update of the indicators'.

If she still doesn't for you, let me know and I can send you a simple example (if you need an example, let me know what version of the VBAI you are using).

Thank you

Brad

    Hey,.

    I was checking for error 66, I think that it check if the connection has been closed in order to reconnect

    do you not think that the error 56 or 60 are better?

    with respect,

    56 is the time-out. This will depend on your remote service if this should be considered as error or ignored. If it is a server application, it should certainly be able to respond within the time limit. But if your host application is the server and the remote application is the client it is very common to receive a time-out error when querying the client if it has new data to send.

    Order the examples mentioned previously, they really give you a good idea on how TCP/IP network communication must all work, even if there is still a lot to improve to create a truly reliable connection. But start from there come back if you get into trouble.

    How to test my BlackBerry 6.0 application that will look good on the screen 9670's 360 x 400?  I don't see how to configure the size of the screen of the Simulator.  (fledge.exe / Pocket = 9670 does not work)

    The application uses 6.0 features, so I can't just run it on a Simulator 5.0 with a screen 360 x 400.

    You will need to download the BlackBerry Style 9670 Simulator.  You can download it here: http://na.blackberry.com/eng/developers/resources/simulators.jsp

  • How to test moduleDeletionsPending, in the Simulator, I don't have the option to remove my application

    How to test the following?

    I want to test the functionality by using the method public void moduleDeletionsPending (String [] moduleNames). I had written logic that removes files from an SD card and it works when I call a menu inside my application item.

    However, it should only be run when I uninstall the application.

    In 9700 Simulator, if I select Options > Applications > [highlight the application] > [open the menu by pressing the Insert key on my keyboard] - I don't see the option to remove the application.

    I don't see the delete option for other applications, such as the Klondike card game.

    Should I set a property or the permissions of my app should be deleted in a simulator, so I can test the moduleDeletionsPending method?

    Thank you.

    You will need to 'install' the app in the BlackBerry smartphone Simulator so that your application appear in the list of applications.  You won't see here when you perform an execution/debug as, when you use the file, the option of loading or copy it into the directory of Simulator.
