Gel application - "the required samples are not yet acquired.

Hello

I have a vi that controls a test bench. The vi was created using Labview 8.6. Vi works fine and controls to the test correctly when running on the pc where it was created in the full version of software development (which is not converted into a stand-alone executable).

The problem occurs when I create an executable file and try to run it in another pc. Initially the application seems to work ok but then after a random time (anything between 30 seconds and 12 hours), the application starts to turn slowly and then loses communication with the hardware (cDAQ-9178). After what happened when I opened MAX and try to run the task I get an error message that says that «some of the requested samples are not yet acquired...» »

When the application starts to slow down, I see a reduction of the available physical memory and one of the CPU usage increases to 100%.

I built the application using Labview 2012 and use MAX 5.3.1 on the pc hosting the executable file.

Below, I have included a screenshot of the area of the block diagram which is probably more relevant to solve this problem. In MAX, the task is set to continuous samples, 1 k samples read at the rate of 1 k.

Anyone have any suggestions for me to try please?

Thank you

So now, you can try what BCL@Servodan suggested. Create and launch tasks with DAQmx before your loop and see if it helps. Remove the timed loop would be also advised, and you set the sampling frequency before the normal while loop, as in the official example.

This would not require too much effort and can help...

  • Some or all of the requested samples are not yet acquired: API change responsible?

    My Delphi program, which works very well under NOR-DAQmx 8.9.0f4 on a set of material, fails under 9.0.0f2 on what I received insurance material is equivalent. The error is «some or all of the requested samples are not yet acquired...» ». This happens even to slow scanning rates, and coming to suspect that the API has changed subtly in the transition from version 8 to 9. What is the probability is it? Now that I have access to the source code on the new hardware (NI PXI-1044 with computer integrated PXI-8110) is there something I can do to check this?

    Hi Francis,.

    Your program still calls DAQmxCfgDigEdgeStartTrig() for all the tasks of the slave? If you do not do this, the devices are beginning to acquire data at the same time, and since you pass 0 for the timeout parameter to DAQmxReadBinaryI16(), out-of-sync devices could certainly time-out errors.

    In addition, you must ensure you start the slave devices before the master device, so that they're already waiting for a trigger at the start of the master device.

    For the third part of the applications that perform many tasks, I usually discover www.tucows.com and www.download.com.  They have a wide variety of programs, and the trick is to put in the correct search terms to find what you are looking for.  Make sure you that your selection is compatible with Windows Vista and at tucows, try to pick one with 4 or 5 cows because they are the highest rated.

  • The required fields are not displayed message when left blank

    Hello

    I set fields as required in the value, the field Type as user entered - required tab. Also, I entered a message in the empty Message field. When the user fills out the form, they are allowed to send the form without fill in the fields.

    Any help is greatly appreciated.

    Thank you

    Use the preSubmit event to check required fields / required before sending...

    Check the wire for ideas below.

    http://forums.Adobe.com/thread/606762?TSTART=0

    Usually, if you use the required field and submit the form, it will display the warning message that the required fields are missing, and continue to submit the form. It is therefore preferable to use the programmatic approach for the control on the form submission.

    When you search for the values of field programmatically, you must set the Type property of the value type as input by the user - option.

  • Search for Windows 7, why not if give me the files that are not yet in my augument search?

    Windows 7 Home premium 64-bit OS.

    Have a lot of files are duplicated.

    In Windows 7 lets say the files in the folder have files that look like:

    Bill 120.le rar
    Bill 121, rar
    Bill 1 .rar

    and we want to remove duplicates with '(1) '.
    and we enter research * (*)

    Under XP it would only list the file: Bill 1 .rar IF you entered *(*.)  or *) * or (1), etc.

    Bill 1 .rar

    In Windows 7, since I started to use Win 7 years, everything I do is get frustrited when it will sometimes give me what I ask for the Bill 1 .rar.
    but most of the time like now, will give me ALL the files WITH and WITHOUT the "()".

    Bill 120.le rar
    Bill 121, rar
    Bill 1 .rar

    WHY?  and how can he give me what I asked?

    (I tried ALL the settings and they all do the same thing)

    Enter in the search box:

    name: ~ = "{}"

    The ~ = indicates to Windows 7 search to look anywhere in the name.  Usually, the quotes would not be needed, but( ) has a functional use of search for Windows 7, and the quotes tell Windows 7 search just deal with ( ) as a chararacter.  I tried to find a way to search for a (?), after? as a wildcard but couldn't.  [Update: solution concludes, at the end of the post]  However, you can enter this to search for files named with the two ( and ), but not necessarily appearing in the (#) form.

    nom : ~ = "(" nom : ~ = "")" »

    or more compactly,

    nom : (~ = "(" ~ = "")" »)

    Update: more than a month later, I realized the more compactly.  Subsequently, the? is interpreted as a wildcard character.  If more digits is possible, then additional search with? exactly two for? for exactly three and so on.

    Name: ~ "* (?) *"

    If filename: is used instead, then the tilde is redundant:

    filename: "* (?)" *"

  • Updates (optional) must be blocked if the essential addons are not yet compatible

    Example: I depend on Roboform to maintain several hundred secure passwords unique and credentials of the user. Updates to firefox often break the addon. I should be able to say thank you to any updates until the addons have caught up.

    At the present time, which requires an uninstall firefox and reinstalling the older version.

    (a) is there a better solution to workaround?
    (b) when the (delay until addon compatible) option will be made available?

    Third party products/software (e.g., Roboform, Adobe Flash, RealPlayer, products firewall-AV/AS, etc.) should be checked periodically by the user for the updates. Some third-party products, including Roboform, install an add-on (toolbar or another) in Firefox. Keep the third-party products updated is also important to keep your operating system updated.

    Regarding the Roboform and their version compatibility page: http://www.roboform.com/support/news (information I found on the internet indicates that Roboform 7.6.3 was released on 10/11/2011 - two days after Firefox 8 is out. Many/Most of third party vendors won't release updates before or shortly after the official public release of a new version of Firefox).

    For example, on the date of your original question, you must update the following third-party products who have installed 'Plug-ins' in your Firefox:

    • These would be covered in the lower part of my post 'not related to your question, but... "You may need to update some plug-ins '

      • Shockwave Flash 11.0 r1 (aka Adobe Flash) - you are at least one or more updates to date behind
      • Adobe PDF plugin for Firefox (Adobe Reader) - you are at least one or more updates behind
      • Next-generation Java plug-in 1.6.0_20 (Java) - you are 9 updates behind
    • The QuickTime Plugin - you must check with the QuickTime site
    • Foxit Reader plugin - you need to check with the Foxit website
    • npFFApi - part of ZoneAlarm Toolbar; You must check with their website. The current version is 10.1.065.000.

  • Windows 8 pro applications say that they are not connected to the internet

    I just installed Windows 8 pro and after installing, everything worked well. However, now all applications say that they are not connected to the internet.

    Shop Windows says "you're PC is not connected to the internet," However, when I go to the Office the internet works fine.
    How can I fix?
    I tried to make a new account and check my internet options, but nothing seems to work.

    After much more research online, I was able to find the problem for my computer. Before moving to windows 8, I had AVG internet security on windows 7, and apparently that's what was blocking the applications to connect to the internet.

    So if you have some type of antivirus or internet security installed, try to remove them to see if that makes a difference.

  • "The build tools are not installed.

    I run an xp windows 2003-04. My computer does not start completely and if I click on debug or put end to the program there just restarts the computer. How can I solve this problem? and is it possible that I can update my software?

    You say that you can not even start in Safe Mode, so method 1 will not help you, method 2 will not help you and 3 method will not help you.

    I start in the XP Recovery Console and first run a chkdsk/r on the afflicted system, but since we don't know anything about your system, we will need more information.

    It is a shame that in the forums MS Answers, the first response to a new question is (or should be) a request for more information...  You are 5 days in your problem, and so for him it seems that you are not getting anywhere.  If the thread goes inactive for more than a few days, the response of the Microsoft Support Engineer will become the 'response' automatically because it has links to the KB articles.

    Since the Microsoft Answers forum does not have any kind of information system request when a new question is asked, we know absolutely nothing about your system.  Not knowing the basic information a problem prolongs the frustration and the agony of these issues.

    Thank you MS Answers, allowing the resolution of simple problems as frustrating and a lot of time as possible.

    Provide information on your system, the better you can:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Your system have IDE or SATA disks?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a working CD/DVD (internal or external) drive?

    You have a genuine XP installation CD bootable, which is the same Service as your installed Service Pack (this is not the same as any recovery CD provided with your system)?

    If the system works, what do you think might have changed since the last time it did not work properly?

  • Prevent the 'Send Email' dialog box until the required fields are filled

    I am new to JS and fight with a last piece of code.

    I have a form with several fields. I send the form as an attachment to e-mail and need the required fields completed before the form can be sent by e-mail.

    Currently, I have a display alert message if all of the required fields are empty, but if I cancel the box warning, the 'send Email' dialog appears immediately and I can send the form even if the required fields are empty. I want the 'Send Email' box to appear only after completing all the required text boxes.

    The problem seems to be with the if/else line (IF all fields req. are empty, send alert. OTHERWISE open the box "Send email"). What is the best way to write this? Ideally, I would like to alert to list specific areas that are empty. Here is what I have at the moment - but obviously something wrong):

    If (requiredFields.length > 0) {}
    App.Alert (Error);

    } else

    Talk with someone @ Adobe (through our IT people we actually received a CONF. call w / an Acrobat expert!)

    It turned out to be the word "subject" in our Javascript. The word
    "subject" is a reserved word in newer formats and is read-only in
    Drive.  So we had to redefine the word & read "subject".

    Works great!
