How to set a boolean variable to be true each x amount of time

hello,
Any ideas of how to create a boolean variable in labview which will be true only let's say each 2 seconds ? the rest of the time it should be false
Regards
Charis

Charis,
what is the context of such a "variable"?
The question is very important as it is a common mistake to have "variables" in dataflow programming languages like LabVIEW.
That being said, you have to implement a loop with proper timing to toggle the boolean value. You have to look for good propagation methods to make this value available in other parts of your software.
If the software is a single loop, the implementation is easy. It requires a shift register and a state machine (which includes other states as well performing the actual task of the program).
If the software is more complex, propagation from your "toggle loop" can be done by an Action Engine or a notifier.
Also, you have to define how long the boolean should be true as you only stated how long it should be false (2 seconds)....

  • How to set a session variable

    Hi,
    I would like to know how to set a session variable for the following purpose.
    At the top of my application I have a "Welcome <username>" I'd like it instead to have "Welcome <firstname> <lastname>".
    So the concept would be after the user logs in succesfully this session variable is dynamically set so it can be displayed.

    Hi Scott,
    I realize that I can set items etc in pages. The case I'm referring to is a reference in a template. My template has a "Welcome <user name>" ... so the code looks like "Welcome &APP_USER." Anyway to make it say "Welcome first_name last_name" in the template? Note I'll have to get the first/last names from a query

  • How to set a bind variable across the pages in a report

    I want to create a portal report where data will come from a table for a date range for a week.
    For e.g select event_date,last_name, event_name
    from RESOURCES
    where event_date between trunc(to_date(:curr_date,'DD-MON-RRRR'))
    and trunc(to_date(:curr_date,'DD-MON-RRRR')+ 7)
    The :curr_date is defined as a bind variable whose default value is sysdate.
    Now, when we run the report for the first time, it takes the :curr_date as
    sysdate and prints the report.
    I have two buttons in the report output like "previous week" and "next week".
    If someone presses previous week, the same report should run with curr_date
    as sysdate-7 and if someone presses next week, the report should run with
    curr_date as sysdate +7 and also the :curr_date sets to sysdate - 7 or sysdate + 7
    depending on the button pressed.
    Problem:
    How do I set the value of curr_date if someone presses any of
    previous week/next week.
    null

    Best to state your JDev version, and technology stack (eg. ADF BC) when posting.
    I can think of 2 approaches.
    1) Create a parent VO based on SELECT :bindVar FROM dual, then create links between your other VOs and the parent
    2) Create a AM client interface method that programatically sets the bind variable in each VO.
    Can you specify your use case? This one tends to come up when discussing effective from/to dated queries.

  • How to set a bind variable into a vo query from the current vo ?

    I would like to exclude from my list of values defined in a view object the already referenced items in the current view object content.
    Let's say i have dept and emp with a many to many relationships, I would like that the already existing dept for emp not listed (excluded) in the list of values for emp.
    Do i need to define a bind parameters and set it during search or is it possible to use an expression that will refer the current row attribute representing the dept ?
    I didn't find an example or explanation how to set bind parameters defined in a view object query from seach pages or list of values ui components. May be somebody know how to find the info.
    Thank you

    I think that bind variable accessors in the VO class is what you need. You can override the getter method of the bind variable "LocaleCode2" in order to return the first 2 chars from the bind variable "LocaleCode". Have a look at this blog post for details:

  • How to set a display variable

    Hi all,
    we have oracle EBS 12.1.1 installed on suse linux servers in our setup. one developer is using dev tools to have some graphs displayed while generating reports. all of a sudden we find that the graphs are not getting generated.
    i am told that it is because of the DISPLAY variable in Linux. I am working as a Linux admin and I am not too sure how to set it.
    i went to the company's data center to get to the console of the Linux box. I logged into the GUI and ran these commands
    linux-43x3:~ # echo $DISPLAY
    :0.0
    linux-43x3:~ # export DISPLAY=:0.0
    linux-43x3:~ # xhost +
    access control disabled, clients can connect from any hostsince the display was showing :0.0, there sud not v been any issue in my opinion, but still i chose to run the export DISPLAY command.
    still i find the graphs do not show up. should I run the command as root or should I run it as an apps user? and further if I log out of the GUI will the graphs still work?
    i dont have much experience with oracle apps. please excuse me if this question is too silly

    Hi,
    >but still i chose to run the export DISPLAY command.
    No problem if you set DISPLAY:0.0 AGAIN
    should I run the command as root or should I run it as an apps userRun as both users.
    should I run the command as root or should I run it as an apps userIt'll work, Unless you reboot the whole machine.

  • How to Set up the  variables and others to compile and Run Java Programs

    Hello,
    I have just downloaded the jdk1.6.0_07 and jre1.6.0_07 and installed it in C:\Program files\Java in my Windows XP ,So please tell me how to sett up the enviroment variables etc to compile and run Java Programs from Command Prompt.
    thanks

    To set the PATH permanently, add the full path of the jdk1.6.0_<version>\bin directory to the PATH variable. Typically this full path looks something like C:\Program Files\Java\jdk1.6.0_<version>\bin. Set the PATH as follows on Microsoft Windows:
    1. Click Start > Control Panel > System on Windows XP or Start > Settings > Control Panel > System on Windows 2000.
    2. Click Advanced > Environment Variables.
    3. Add the location of bin folder of JDK installation for PATH in User Variables and System Variables. A typical value for PATH is:
    C:\Program Files\Java\jdk1.6.0_<version>\bin

  • How to Set multiple Global Variables without using Controls or Indicators

    I have to set many Global Variables (i.e. declare and initialize them) in a subVI in order to pass them to various other subVI's. The only way I know how to do it in LabView is to create a Globals.vi on which you create a control or indicator for EACH Global Variable. That's fine if you have only a few variables. But I have close to a hundred Global Variables (which come from a configuration file for a large program) and clearly it is impractical and cumbersome to create a control for each global variable. In Agilent Vee, there is a simple function called "Set Variable" that sets the data value of a global variable. Then in other module, you simply use the "Get Variable" function to get back the v
    ariable and its value.
    In LabView you can use the "Invoke Node / Set Control Value" and "Get Control Value" properties to achieve the same thing. But as mentioned above, you need to create a control for each global variable and that is a big pain in my case, with many global variables. Furthermore, the global variables are read from a Configuration Text File to this VI. Is there a way to do it without using the control? Thank you in advance for any help.

    Actually you could create the same sort of facility in LV. All you have to do is create a LV2-style global that behaves as follows:
    To write a value to it, you supply a value name and the value. These pieces of data are save internally in seperate arrays.
    To read a value, you supply a value name. The VI looks up this name in the value name array to return an index into the value array. Output the value you find.
    Frankly though, it sounds like what you really need is not hundreds of globals, but a good way to manage configuration data.

  • How to set the bind variable on page load and execute query ?

    Hi All,
    I am using Jdeveloper 11.1.1.5
    I have a table called "Employee"
    Columns :- id , name , location
    Data :- 1, ,james , chicago
    2 ,Raj ,capetown
    Now i have another webservice(created as a webservice dataControl) which sends me the "id" on each time my page loads.Now the id which has been returned by webservice should be incorporated in my VO Query as in where clause to fetch the data for the respective "id" in that "Employee" table and should be rendered on form.
    Eg :- Id "2" has been sent by the webservice then the record should be fetched from database should be "2","raj","capetown".
    I know that there would be necessity of bind variable , but how do i set the bind variable on page load ?
    How can i use the bind variable appropriately ??
    Please suggest !!!!
    Thanks.

  • How to set a boolean webservice parameter to null

    Hi all,
    is it possible to set a boolean input parameter of a webservice to null?
    False and true works well, but is there also the posibility of setting it to null?
    Greetings
    Florian

    I will try to explain.
    Our webservice has a boolean input parameter. And it acts like the follwing pseudo-code:
    IF bool_arg == null
       action1;
    ELSE IF bool_arg==false
       action2;
    ELSE IF bool_arg==true
       action3;
    ENDIF;
    With the value NULL i mean that the input paramter is not in the SOAP-XML.
    But with Visual Composer i only manage to set the value to true or false.
    I cannot find a way to set it to null (which means it is not in the SOAP-XML).

  • How to set the DISPLAY variable to run admsi.pl?

    Dear Experts,
    I'm trying to patch Oracle apps R12 using admsi.pl.
    hostname: black
    APPS db: VIS
    But I keep getting the error:
    Please set the DISPLAY variable and re-run this script
    This is what I did:
    VIS database and listener are already running.
    login to the linux server as unix user: applmgr
    cd /oapps/applmgr/VIS/apps/apps_st/appl/
    . APPSVIS_black.env
    cd /oapps/applmgr/VIS/apps/apps_st/appl/ad/12.0.0/bin/
    admsi.pl
    Invoking Oracle Patch Application Assistant....
    Please set the DISPLAY variable and re-run this script
    huh ?
    set | grep -i "display"
    DISPLAY=:0.0
    set | wc
    435 486 25235
    I notice that there are 36 .env files!
    For applmgr alone!!
    find /oapps/applmgr/ -type f -name "*.env" | wc
    36 36 2626
    For oracle, there are another 7 .env files!
    find /oapps/oracle/ -type f -name "*.env" | wc
    7 7 513
    Did I get the environment (env) file correct?
    Or do I need to run a few more env first?
    If so, which ones?
    What would the order of operations be?
    sqldeveloper has given me problems with Display sometimes.
    But even sqldeveloper works fine.
    What is the secret to get admsi.pl to run in the normal manner?
    Thank a lot!

    Thanks a lot, that worked! So the perl script was wrong.
    In the meantime, I had done this, and it seemed to work:
    admsi.pl -debug
    Gathering Information..
    Enter the patch_top : /oappsinstall/update12.1.1/7303030
    Enter the APPS user password:
