Need an example how to use SCAN_Start with a callback function

I would appreciate if someone helps me with a working example of how to use SCAN_Start with a callback function. I need just a basic functionality: to specify a channel list (with gains probably), to start a data acquisition task and to receive data buffers utilizing a callback function. t this time whatever I was trying to do caused computer hangups, though it is supposed to be one of the most regular tasks to perform.
Thank you in advance,

Hello Mike,
Thank you for contacting National Instruments.
Attached is an example project which uses a callback function to begin analog acquisition (AI) by calling SCAN_Start. This project acquires from the first 2 channels on your DAQ device. Make sure to modify the device number in the code to match the number of your card.
Let me know if you have any further questions...

  • How to use setSoTimeOut() with socket ??

    HI All!
    I eagerly need to know how to use setSoTimeOut() with socket (on server side).
    How can i do that??
    Any help with example will be appreciated!!
    Thanx in advance

    you'd have to do something like this:
    (this is all assuming you want to read Strings from the socket. setSoTimeout works for any read() call to the InputStream associated with the Socket)
    ServerSocket ss = new ServerSocket(myPort);
    Socket s = ss.accept();
    s.setSoTimeout(5*60*1000); // 5 mins * 60 secs * 1000ms
    BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
    boolean running = true;
    String readIn = in.readLine();
    // do whatever you want with the data read
    running = false;
    Now. That's what I think needs to be done. I don't have Java on the machine I'm currently on, so I can't test/verify it, but it goes something like that.
    Good luck,

    I have a situation here, I need to learn how to use

    . Can I connect to a MYSQL DB with servlets?Yes... documentation to help you connect to any database can be found at To connect to MySQL, you'll need drivers (, and the specific connection URL for those drivers will be included in the documentation.
    how can I build an e-mail server with java (no matter
    how difficult)If you're fairly new to JSP/Servlets, you may be in over your head here, since an email server is no easy application to code. Here's a link to the source code for the JAMES project... Apache's Java email server... maybe you can find some useful information there...

  • How to use Count with Date Parameters

    I am having issues using the Count() function in conjunction with date parameters.
    This is a Siebel report and in my report I have 2 date parameters(From Date, To Date). In a nutshell I am basically trying to count Opportunities that has a start date within the given date period. However I don't see a reasonable way to put my date parameters within the Count() function. The reason being is that I need to have a huge chunk of code to convert the dates into a common format that can be compared, and it won't even fit within the code block in my rtf template. I am not even sure how to put multiple conditional statements inside a Count() function since all the examples I have seen are very simple.
    Anyone have a suggestion on how to use Count() with date parameters?

    Any chance you can get the date formats in the correct format from siebel?
    I don't know Siebel - so I can't help you with that. If you get the correct format it is just
    <?count(row[(FromDate>=date) and  (date<=ToDate))?>
    Otherwise the approach would probably need to use string function to get year/monthd/day from the date
    and store it into a varialbe and compare later the same way
    <[email protected]:from; ....?>
    <[email protected]:to; ...?>
    <?count(row[($from>=date) and  (date<=$to))?>
    Potentially you can use the date functions such as xdofx:to_date to do the conversion
    But I am not sure if they are available in your siebel implementation.
    Hope that helps

    how to use jdeveloper with linux?
    Hello, i've download jdeveloper, and i have java1.4 installed. But i can't run jdeveloper i have jdev.exe and jdev but when i put /usr/local/jdev/bin/jdev a have a message like file not found. I don't know what to do.
    Help please!!!

    You need to go to the directory where you unzipped JDeveloper, for example:
    cd opt/jdev/jdevj2eebase1013/jdev/bin
    Once there, do this:
    chmod +x jdev
    chmod +x ojc
    Now you can try this:
    nohup ./jdev &

    I usually create a soft link in ~/bin

  • How to use Terminal with KeySpan USB serial adaptor cable?

    I own a KeySpan model USA-19HS to use with our MacBookPro when working on clients networking equipment that require serial communication. I have used ZTerm with excellent luck, but it costs, and is yet another application that I dont really want. I would like to know if any one out there has exacing instructions on how to use Terminal with this adaptor. If I could write a file that had, say, the couple most common settings (9600-8-n-1, 57600-8-n-1, et cetera) that I could simply click on, to open a new Terminal window with those settings, then simply close that, and open a new window (apple+n) in order to get back to a default settings terminal window. All feedback is most appreciated.
    Thanks so much, Jason Sjobeck

    Hi, Jason. Welcome to the Discussions.
    You wrote: "All feedback is most appreciated."OK.
    1. Have you considered discussing this with Keyspan Support?
    2. Have you read the section "OSX has - why do I need ZTerm?" on the ZTerm Home Page? That seems to explain why one needs an app like ZTerm.
    3. A quick search of Keyspan's FAQ for your product and terminal doesn't yield much more than how to find the serial ports using Terminal.
    Likewise, this Google search also yields little, and variants of that search of such weren't particularly help either.
    It appears your inquiry seems to be a somewhat esoteric topic.
    4. Apparently, ZTerm X is a bit long in the tooth and there's no Universal Binary for it. It sounds, however, like you've tried it running on your MBP under Rosetta, yes?
    5. In researching alternatives to ZTerm for you, I note the followng:• The comment from "Reverb" on this page suggests C-Kermit or Kermit as a free alternative.
    • This tip on Mac OS X Hints cites Minicom as another option.6. You may want to try your question on the Unix Discussion.
    Good luck!

  • Help me!! How to use JavaScript with JSP ??

    I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
    The page has a ListBox where list items are populated from the database.My requirement is
    whenever the list is changed the page shuold be refreshed with the selected item info.
    I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
    Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.
    I have one more question...I have gone through the JSP samples in OTN and I am trying do download the sample 'Travel servlet' which show list of countries...etc
    I have also gone through the 'readme' but I don't know how to extract .jar file.
    I would be great if you could help me in this.

    We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
    Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
    Do you know of any way to dynamically query the the Oracle database in Javascript

  • How to use assert with wireless toolkit?

    I am trying to find out how to use assert with wireless toolkit. I have found that I need to pass "-source 1.4" to the java compiler. But I can't find any documentation on how to do it.
    I'm using J2ME Wireless Toolkit 2.2.

    Here's a quote from an article on Java World at
    "To support the new assertion facility in J2SE 1.4, the Java platform adds the keyword assert to the language, an AssertionError class, and a few additional methods to java.lang.ClassLoader."
    So I really think it's part of 1.4.

    OTOH a Swing JApplet inherits the mouseDown method from Component, and it was deprecated in Java 1.1. The documentation (JavaDocs) provides instructions on what to use instead.
    is there any way to use it or any other alternative is available for this?
    if can provide me a sample code.>If can provide me cash. Short of that, you might actually need to do some research/coding of your own.
    As an aside. What does any of this have to do with Java 2D?

  • How to using ical with two separate iphones

    trying to understand and learn how to use Ical with 2 different Iphones, using Icloud.

    To sync iCal across computers, the calendar needs to be published to a server. This can be a local server that you can set up, or it can be something like google or microsoft exchange or apple's mobile me. The best bet may be to wait until fall and see what iCloud offers!
    Sharing your screen can be accomplished a few different ways. You can have two iChat accounts set up, and have one logged in on each computer, and then use iChat's screen share feature. The other way is to go to System Preferences, Sharing, and then check the box next to Screen Sharing. You may have to adjust some of the settings in there, but give that a shot.
