LabVIEW makes my web page hang when it updates the data of access database

Hello

I'm working on labview (signal acquisition and insertion into a database) and visual studio (Web page design) and I faced this problem when the Web page tries to update the database of microsoft Data Access.

Whenever I VI, DQA will acquire analog input from a circuit and pass the value in a database for the Web page retrieve and update and display the latest data on the Web page. But for some reason, whenever I run the VI, the data refresh is is arrested to the Web page and updates only when I stopped the vi and whenever I try to refresh the page, it will display a runtime error. I wonder if it is possible to do the update of page Web in real time instead of simply update that when the vi is stopped and what are the causes the Web page to stop the update (labview Web side/page side).

I use IIS to host the Web page and labview 8.6/toolkit database connectivity for data acquisition and store it in the access database.

In my view, that it is a limitation of the Jet database. If I remember, Jet uses the locking of the 'page '. Exactly the same thing happened to me on a large scale with several testers. The solution was to use a sophiticated more like MySQL or SQL Server Express database.

  • Why have I lost my web pages centered when I updated the site?

    Need urgent help focus my web pages after you make updates to the site! Only the index page is always centered. I use an external stylesheet, but did not make any changes to it (I don't think) when I updated the site. I think I have the margins and the text defined as recommended. I must have screwed up somewhere, the CSS, but can't find it. Can someone please look at the URL?  www.labreastspecialists.com

  • said CF administrator to connect to db is ok but the web page says unable to find the data source.

    I was able to connect my 10 coldfusion administrator mysql database, using the mysql(4/5) driver.  However when I try to perform a query in a Web page, I get an error saying page:


    The data source is not found

    Here is the code snippet:

    < cfquery name = "dump" datasource = "newsletter" username = "root" password = "*" > (my password is correct)

    Select *.

    newsletter of

    < / cfquery >

    < cfdump var = #dump # >

    Any help would be appreciated.

    I realized that it was.

    I had installed Coldfusion 9 times and 10 of Coldfusion.  It seems that I was getting the database connected with Coldfusion 9, but then I was building and running on the server, coldfusion 10.  Uninstalling coldfusion 9 and ensuring that the data source has been connected to the coldfusion administrator 10 solved the problem.

  • Get rid of Web page errors when connecting to the webvpn

    It's on an ASA5505

    I have a question about the resolution of errors in the web browser when you try to access my vpn ssl interface to download Anyconnect.

    I use self-signed certificates.

    The webvpn page that will allow users to connect to get the anyconnect client.

    For webvpn page I do not use a domain name FULL only her public IP address of the external interface.

    For example, I want the clients to connect to https://x.x.x.x/AnyConnectVPN and get the anyconnect client. They will receive the webbrowser error, noting that the certificate is not approved. After that install the cert to the root that goes now, I'm trying to keep from getting the error "The URL that you use to access the site does not match the name in the certificate."

    Can I specify the exact page I want vpn users to enter the name of the object CN?

    Crypto ca trustpoint Identity_Certificate

    LOCAL-CA-SERVER key pair

    ID-use ssl-ipsec

    no name FQDN

    name of the CN=x.x.x.x/AnyConnectVPNobject, OR IT_Dept, O is is BUSINESS of TEST, C = US, St = FL, L = Daytona[email protected] / * /

    Thanks for the help.

    Triton

    The trustpoint you created needs to have the subject name of "CN = x.x.x.x", you do not need to include the "/ AnyConnectVPN".

    Hope that helps.

  • How to make a web page which changes each time the user refreshes? Is it possible to Muse?

    Hi, I would like to make a simple site where the main text in the center of the page changes whenever the user refreshes the page in their browser. I guess I'll have to do a master and several pages that are all the same except for changes in the text, but I don't know how to make sure each update goes to another page and not just the home page? Is it still possible in the Muse?

    This is an example of what I'm going: : procatinator:

    Thank you!

    You can't do it with only Muse. Would be probably pretty simple to do with a bit of Javascript. Check the widget directory such that it is possible that someone has made a widget for random content. If not, maybe I'll do one this weekend. ;-)

  • I downloaded my app on github folder and also try to download the zip at phonegap build Web page but when I download the apk it opens the app Hello wolrd... Why?

    I download from github, it loads the name of my application in the app info section but in the description, it seems the description for the Hello world app.

    I tried to download the zip file from directly and there still show the description of app world Hello and when I download it, it opens the app world Hello showing "camera ready."

    I changed the XML and seems not to care about it.

    What can be? why it does not show my application?

    Hi, I solved the friend of the question. It was happening because I have download all the files generated by phonegap desktop app from my app to github. The solution is to download only the www folder and the config.xml file. Thank you for your time.

  • is it possible to make a Web page expires? Is there a setting in dreamweaver or html text that will make a site Web do not load a page after a certain date?

    is it possible to make a Web page expires? Is there a setting in dreamweaver or html text that will make a site Web do not load a page after a certain date?

    You should probably give us more info on what you are trying to reach.

    I have Web sites that display information on the courses, with the possibility to register online. We do not want the announced course when their departure date has passed, so they are automatically removed from view. In this way, we have thousands of courses by year announced without worrying that the old courses are still on Web sites.

    To do this, the PHP and a database are used. Registration of database includes the date, which is verified by the query sent by PHP.

  • on some Web pages only you use firefox, the display text is sometimes glitched.

    OK, sometimes the text is glitched on Web pages. and if you highlight the text messed up it will be instantly normal. also have the most updated drivers. and this only happens with firefox.

    Hello trentenmarschel, try disabling graphics hardware acceleration. As this feature has been added to Firefox, it has gradually improved, but there are still some problems.

    You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

    Then perform the following steps:

    • Click on the orange top left Firefox button, then select the 'Options' button, or, if there is no Firefox button at the top, go to tools > Options.
    • In the Firefox options window, click the Advanced tab, and then select 'General '.
    • You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
    • Now restart Firefox and see if the problems persist.

    This solve your problems? Please report to us!

    Thank you.

  • I am now on iOS 9.2 Game Center still does not work. When I open the app it freezes on a blank page. When I open the Game Center in the settings, it freezes and then crashes. Please Apple can solve this problem of Game Center iOS 9.2.

    Hello Vaishnav,

    Thank you for using communities of Apple Support.

    I see that you are having problems with Game Center on your iPhone. I have a number of things for you to try.

    First force quit Game Center.

    1. Press the Home button twice quickly. You will see small glimpses of your applications recently used.
    2. Swipe to the left to find the Game Center app to close.
    3. Swipe up on the preview of the Game Center to close.

    If this does not work, then the next step would be a restoration. I recommend restore like new, without backup restore and everything first. If it works there, you can restore the backup.

    Use iTunes to restore your iPhone, iPad or iPod to factory settings

    Best regards.

  • Why my HPLaserJet P1102w not print Web pages, but it will print the pages of the notebook, etc. ?

    My HPLaserJet P1102w (with Windows 7, Firefox) does not print Web pages.  I can see the pages I want to print in the queue of the printer, but they never proceed with printing.  I see a blue light sometimes flashes on the computer.  Looks like he's trying to find a wireless connection, even if it is attached to my computer through a USB port under the guidance of the option given in the directive.

    When I copy and paste text into My Notebook application, it prints on my printer - but when I click on "print" on a Web page, it will not display the page.

    I think I can remove the question.  I discovered that Firefox is trying to use a printer I own is no longer.  I think I can understand it from here.  Obviously, choose my new HP printer for printing from Firefox.

  • I can't get the page numbers in my table of contents to update when I update the book.


    I use Framemaker 11 and I have two tables of contents in my book: one in English and French. Each table of contents to links to various documents in the same book. The reference page for each table of contents is defined and properly displays the positions 1 and 2, I said that it appears, but numbers not updated when the contents of my document files change to another page. I checked the settings of conditional text in my document files; they are correct. When I update the book, I choose to update the numbers, all the cross-references, all text inserts, OLE links, generate a Table of contents, lists, and indexes. What I am doing wrong? Thank you.

    If they are not knocked down, then they are certainly not generated files. See the example in the help of FM11: http://help.adobe.com/en_US/FrameMaker/11.0/Using/images/bk_hier_books.png

    The 'K' is a TOC file that FM recognizes a generated file.

    Because you have created your table of the contents of the French with the help of another structure of the book, you could import reference this TOC file in another file of FM (for example to create an inset text) in the main book you want. However, you need to make updates in two steps. First update the French book to revise the table of contents. Then update the main book to get the rest of the correct pages (and given that the table of french contents are imported by reference, FM always uses the most recent version).
