• How to create a task that runs once a day, immediately after the opening of session?

  Hello, I'm wondering how to create a task using the Task Scheduler that runs once a day, immediately after I have logon.

  The reason is I want to use Bing Desktop to change my wallpaper every day. However, I just want to run the first time I start my computer every day, so it will change the wallpaper. By default, it starts whenever I have to logon. It's annoying, because I just want it to start once a day to change the wallpaper. However, using the Task Scheduler, I put only a trigger to start "at the opening of session' or"once a day." If I choose once per day, it runs about 5-10 min after I login, instead of logon immediately after. If I choose the two triggers, then it starts after each session.

  Basically, I just want the Task Scheduler to launch the program after the connection the first time I connect to the computer on any given day. How can I do this?

• Create/edit task DAQmx vs DAQmxCreateTask

  I just started using Labwindows recently, so I'm a newbie here. You have a configuration great forum and I hope you can help me with that.

  so, as the title indicates what is the difference between the use of these DAQmxCreateTask(), the functions LoadTask() and manually create a DAQmx task using the menu 'tools '.

  Don't they realize the same thing? What is the need for each of them to be here? Am I missing something?

  I have already a little used in Labview. In that, to acquire data, we must use the icon tasks DAQmx to acquire/generate anything. but it is not all available such alternative programming, if I'm not mistaken. so, what's the problem with Labwindows/CVI then?

  Tools > generate DAQmx task launches a wizard that allows you to define the characteristics of the task and create the corresponding code. You can do this by yourself by manually writing individual instructions: this can be useful if you already have an existing code that you can reuse with adaptations little or if you have a special need that cannot meet the wizard or simply if you have the habit of writing code rather than rely on assistants which is my option.

  LoadTask is used to load a task created in MAX and use it in your program. This allows a form of customization of the task without changing the source code, with the obvious caveat that excessive changes in the task can cause the end behavior or abnormal length of program errors.

  All these options are legitimate ways to perform the same operation, a task for the acquisition of coding: know the characteristics of each of them, you can choose one that is most suitable to your purpose and your programming habits.

• How to create a spreadsheet with labview file

  I just want to create a spreadsheet file. all the comments I've read shows how to create a text file. or reading/creating a spreadsheet, but is possible to create this spreadsheet through labview?

  Hello Ms. METR,

  When you use an entry in the spreadsheet module, it automatically creates the file and replaces it by default.  If you want to add to the spreadsheet file, then you must enter a Boolean variable under the module on "append?

  If you don't need to create the file and then do the worksheet writing because he wants is the path to the file like: "C:\". Documents and Settings\ User\ bureau\ spread.txt"

  Another way you can do is to write about the path to the .xls extension and the icon and everything will work as an excel spreadsheet.

• How to create own IDE for LABVIEW (such as vision builder)

  Hi all

  My pretty funny question, I know that.

  I like to create Labview Application IDE like Vision Builder.

  How to do this?

  As far as I know that Vision Builder is developed with LabVIEW, the source code of course is not public... But why do you want to create a new IDE for LabVIEW? LabVIEW is an IDE, no?

  I think also Vision Builder uses a lot of scripts and sub-panels, I can't help you much more than that.

  For us - outside NI - script cannot be used in an EXE file, they reserve that for their applications not it will be a difficult task.

• How to create parallel tasks using parallel for loops

  Hello

  I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

  I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

  Is it possible to replace something like

  

  by

  

  and that for performing these tasks in parallel loop (on different cores / in different threads)?

  I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

  The benefits of the Show method in the second photo for me are:

  * takes less space

  * changes need be made only once

  * less blocks, son and other things makes it clearer what is happening.

  * flexibility of the actual number of tasks running (8 available runtime instances)

  * If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

  Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

  Best regards

  Frans

  Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

• How to create a section in labview using the screw configuration file

  I am trying to create a new section in Labview. All I see is the possibilties for reading of the sections and keys, write key, remove sections. Is it possible to write a new article in Labview.

  Thank you

  Brandon

  When you write to a key, you will need to provide a section.  If the section is not there, then it will be created.  Basically, you can have a section without any keys.

• How to create this code in labview

  Hello...

  Please helpe me for that matter

  I have create this code in 'c' in ' labview "..."

  ex c:

  If {portc.f1 == 1}

  }

  ex labview:

  If button is {1}

  led round = ~ led Tower

  }

  Thank you...

  See picture attached.

  Why people insist on the use of knots of property to get the value.  It has the same problems with the race as the local variable conditions, but is extremely slow (forces a thread page on the user interface thread).  In fact, you should keep the value of the LED in a shift register.

• How to create a task and then run it later?

  We have a requirement like this: we insert records into a table. After inserting records, we need a web service ping command and tell him to read the new records.

  We call the WS in a trigger after-insert-for-all-row.

  Can we create employment and in the trigger, use DBMS_SCHEDULER. RUN_JOB ('call_web_service', use_current_session = > 'FALSE') to perform the task?

  When we create jobs, we can use start_date = > null to indicate that we do not want to run the task now, but later?

  Hello

  Yes, you are on the right track. If it is a work intended to be run on demand, then specify a start_date/end_date, nor a repeat_interval.

  You can even create as disabled (enabled-FALSE online).

  Use DBMS_SCHEDULER. RUN_JOB ('call_web_service', use_current_session-online 'FALSE') every time you want to run the task.

• How can I get a graphic display in real time of a task daqmx

  Hello

  I have set up a task DAQmx using the DAQ assistant and the task is to work and produce a graph/data, but not before the task is complete. How can I get a display in real-time of the numberical values or graphics?

  Any help would be really appreciated

  Thanks, Paul

  I could get set the frequency of sampling and to give a regular change of output, but im looking to get this long-term data acquisition. For example, the graph changes everything but 1 - 5 get 30 minutes of data.

  I used the DAQ assistant and labview is completely new to me, if im not sure where it take it from here.

  concerning

  Then you should use a chart - not a graphic. A graph has a story. You must set this. Right click and select "Chart History Length".

  Dennis - the interface is well defined. WebSocket is a standard (with some variations). It uses the web server, although it does not strictly HTTP connections.

  I don't know of a free LabVIEW websocket client implementation. You might be able to detach the screws LabVIEW of HTTP to retrieve part of the initial connection and the logic of the handshake, but.

• How to create the shared library for linux real-time target in labVIEW Windows?

  I use myRIO running linux in real time. In my project, I need to pack some C code, so I tried the node library function call.

  I know that I should use the tools compile cross - compile linux on Eclipse to compile c code in linux .so library. But the problem is that call library function node does not recognize the .so file because my labVIEW runs on a Windows PC.

  What should I do to fix and how to combine C code with labVIEW during programming for devices shipped as myRIO?

  Basically, you must also create a Windows DLL that exports the same functions. These functions can be empty stubs if you do not want to run the code correctly on Windows, otherwise you will need to consider how to implement the equivalent functionality on the Windows API.

  Then you can write in your node library call as the name of the library ". "*" and the name of the shared library Windows ".dll" while the Linux version is called "name of your library > .so". LabVIEW will replace the * after the comma in the name of library with everything that is the preferred extension shared library for the platform it is running on and therefore load the right shared library.

  Alternatively you can wrap call all the nodes of the library in a structure that contains the node library in the case of Linux RT and all what you want to run on other platforms in the case of default or a case of specific platform, call the conditional compilation.
