How can I mark data acquired during DAQ?

I am acquiring analog data from an accelerometer with LabView 6.1 and I need to mark some time points during the acquision to indicate the time at which some events occurs during the measurement. I want to do this by pressing the space bar of the keyboard or by clicking a button of the mouse each time the event occurs. I want that the mouse or keyboard event is synchronized with the DAQ. Haw can I do both things?
Thanks!

Hi Yas,
Just been looking at your problem and noticed it was similar to something I came across yesterday. I will attach a snippet that may help you. If not, just post back and I'm sure we can find something!

    How can I get Data from the Sound cart in Labview? Does a VI exist?

    Yes, there are VIs for acquiring data from Sound cards. And examples too. If you don't have LabVIEW yet, do a search on NI's site for example VIs.

  • How can I mark something as 'helpful'  or 'the correct answer' ?

    I have been posting a handful of questions within the DreamweaverCC forum.
    I notice that there indications that 5 people have marked the replies as 'helpful'.
    How can I mark some of the responses to my posts as helpful ?
    I am unable to do this.
    Under my 'Actions' button it says "no actions available".
    I also do not have the ability to edit my own posts.
    For instance, I have resolved one of the problems and I would like to clean up my own post eliminating the 'noise' and leaving the relevant.
    This is for the sake of others.  I have noticed that one of my posts has 200+ views.  I do not want to waste people's time.
    During the first week of may, the Adobe FORUMS had a message for a couple of days that they were doing a major overhaul of the Forum.
    Since then I am unable to sign in to the forums (or to Adobe.com) from my ipad.
    I upgraded my IOS, and cleared cookies and history.
    note.  Today I was doing a general search on my ipad (w/o) logging in.
    I wanted to see what was out there about header.php.
    I came across my own post (which requires cleanup).
    I came across another person's.  It made me laugh.
    The individuals who were helping him asked him to post his code
    which ultimately ended up in the longest scroll in the world  (hundreds of div ids).
    The responders said 'nightmare'.
    It made me laugh because I am certain that part of my posts elicit the same response (nightmare)
    I would like to clean them up.

    Thanks Hans-Günter.
    Yes, I have noticed that elsewhere. I just do not have those options.
    Okay.  After I clicked my own response to you - then the greenStar 'correct answer showed up.
    So I clicked the 'greenstar' on your response.
    Guess what ?
    Earlier, I emailed Preran because there weren't any options under my 'Actions' button for instance 'edit or 'delete'.
    They are now there !!
    Preran

    thanks !!
    What is the best way to navigate to my own posts so that I can follow them ?
    The only way I can do this is by clicking on my inbox & activity under my profile icon.
    There is a list of the latest responses and emails but it is not really a list of my own posts.

  • How to update cgicmd.dat file during runtime?

    I'd like to know how do update cgicmd.dat file during runtime. For example, I run a report one.jsp as
    http://<machine>:<port>/reports/rwservlet?one.jsp&USERID=uid/pwd@db&DESTYPE=cache&mode=bitmap&desformat=htmlcss
    within this report there is a hyperlink to open another report named two.jsp.
    before creating this hyperlink, I'd like to update cgicmd.dat file with passed in userID, pwd, and connection, so two.jsp can use this key for userinfo
    so I can create hyperlink as follows
    srw.set_hyperlink('/reports/rwservlet?report=two.jsp'||
    '&cmdkey=userinfo&DESTYPE=cache&mode=bitmap&desformat=htmlcss');
    Thanks

    To my knowledge the cgicmd.dat is only read when the OC4J starts, so you would have to come up with another solution. Using Single-Sign-On (SSO) is quite a good idea, and it's there for cases like this.

  • HT4059 How can I mark a book as read or completed in Apple ibook?

    How can I mark a book as read or completed in Apple ibook?

    After researching this further, I have concluded that the update feature is working correctly. What I was expecting was that once the iPod would sync with my Mac, that the updating, including marking the podcast as read would take place at that point. In reality, this function does not take place until I click on "Update" in iTunes. During that process the various blue dots of those Podcasts listened to go away, and Podcasts that are outside the parameters of those I want to retain are deleted.
    So, if indeed, as long as I have completed the entire Podcast, the update functions are working properly.

  • How can I mark event as "done" so that I see this at one glance?

    how can I mark an event on ical as "done" so that I see this at one glance? In outlook this was possible, there was a white line on the left once I had marked the event as "done".

    Greetings,
    If you are new iCal user read this: http://support.apple.com/kb/HT2513
    Events are more along the lines of a...well...event   "Appointment with Dr. Smith"..."Travel to Mexico"..."Jon's Birthday".
    What you are describing is what I would call a task.  iCal offers "To Dos" for that purpose which include a check box for completion.
    Cheers!

    Thnak you very much.

    Hello,
    Still no luck.I am surely doing silly mistakes.Anyway,Here are my workings-
    1> student_mst (id(pk),studentname) and student_guard_mst(id(fk),guardianname)
    2> created EO from both of the tables,made id in both EO as DBSequence and an association was also generated.
    3> i made that association composite by clicking the checkbox
    4> i created 2 VO from 2 EO.
    5> put those VO in Application Module.

    Hi ,
    Now i am able to print S JR MR horizontally.Thanx a lot for that.Now my problem is
    There is one column field which displaying value like S JR MR
    Now i am calculating a value using a function and want to display that value for each vale of above column
    For eg
    The report should display like this
    C1 C2 C3
    45 1-2-3 S JR MR
    45*1 2*45 3*45
    I have created package to make the string 1-2-3 separeate and the fuction is working fine .But unable to print value in bi

  • How can I enter data in an input schedule on a member in the EPM Add-On that is not a base member?

    Hello, all,
    how can I enter data in an input schedule on a member in the EPM Add-On that is not a base member?
    E.g. I want to implement a top-down-planning scenario and I have the following hierarchy:
    Europe
         Germany
         France
         UK
         Spain
         Italy
    How can I enter a value on Europe in an input schedule in order to allocate this value afterwards?
    Thanks in advance and best regards
    Gerd

    Gerd,
    It should be something like below -
    EuropeInput
    Europe
         Germany
         France
         UK
         Spain
         Italy
    EuropeInput shall be kept out of hierarchy and should be a base level member. Users will enter the numbers in this member. In your script logic, you will make use of this member to allocate the data in Bas(Europe) i.e. Germany, France, etc.
    Effectively, after allocation the same data will be rolled up to Europe.
    Many top-down planning would use such work-around as BPC doesn't allow writing to parent node.
    Regards,
    Ashish

  • How can I import data in to the digital word generator in Multisim?

    How can I import data in to the digital word generator in Multisim?
    I just  received this comment from a friend, a RADAR engineer, who has just down loaded Multisim.  He has been using HP/Agilent software.  He has a work around using a piecewise linear voltage waveform with data imported from Excel but this is not really a good solution.  It would also be helpful to import data from Mathcad or equivalent.
    "I thought I was about to be impressed with MultiSim but it ended only in disappointment. There is a word generator in the simulation instrument panel which can drive the DAC with a waveform and it can have thousands of lines of values. I opened Excel, wrote the formula to generate the time and voltage points for a chirp, converted to DAC values in Hex and then went back to the word generator in MultiSim to load the values only to find that you have to enter each value manually. It doesn’t even allow you to paste in a list of values from a text file. I’m not going to type 5000 values by hand. If you get the chance to give feedback to National Instruments please ask them if the paste option can be added to the word generator. MultiSim is useful in many regards, but in this case, it left me with the impression that it is considerably limited in capability compared to what I’m used to."

    Hi,
    You can load your data automatically in the Multisim word generator. Follow these steps:
    - Save your data file (in excel .xslx ir .csv format) on your computer
    - Change the extension of the file to ".dp"
    - Double-click the word generator in Multisim and click on Set...
    - In the Settings dialog box, click on Load and then Accept
    - This will prompt you to select the .dp file you have on your computer, select it and you're good to go
    However, in Multisim you have the option of creating your own custom simulation analysis and instrument.
    I will try creating the instrument and send it back to you but it might take some time.
    Multisim and LabVIEW are very powerful in test automation, with the custom instruments you create for Multisim you don't need to export your data file into excel from LabVIEW (or MathCAD or other tools) and then reload it into Multisim. The test procedure is automated instead.
    Please check this reference design about automated simulation
    http://zone.ni.com/devzone/cda/tut/p/id/7825
    Here is how you can create your own custom measurement tool in Multisim and LabVIEW, but as I mentioned, I will create the word generator and come back to you anyways

  • How can i store data in term of a tree structure

    how can i store data in term of a tree structure

    What a tree is the question. If you just want a fast access, ehats about Hashtable or dictionary classes ? The data there is structured in a tree. For a simple binary tree, you can use something like
    class Node {
    Node(Object data){
       Node left;
       Node right;
       Object data = data;
    void insert(Object data, Node parent){
      int test = data.compareTo(parent.data);
      if(test < 0 ){
        if(parent.left == null){
          parent.left = new Node(data);
        else{
          insert(data, parent.left);
      else{
        if(parent.right == null){
          parent.right = new Node(data);
        else{
          insert(data,parent.right);
    }And so build up a binary tree. The traversing methods can be found in almost any good book (pre-order, post-order, in-order), for search you have just to look at greater/smaller and descend in the tree.
    The Object data can be changed to what you want for storage, String, or primitive Numbers, Vectors ...
    Is that what you search for?
