Problem with Web Builder and MySQL connection


I created a web service VI (see picture attached) to connect my Web Builder application with a MySQL database. The problem is that I get nothing on my exit signs during the call to the web service VI.

Some tests I've done:

(1) this web service VI works perfectly (I mean indicators 'value', 'status' and 'data_hora' give the desired result) when the VI run directly through LabVIEW. MySQL connection and my VI are OK...

(2) I know my web service VI was successfully built and deployed because the indicators give me some value if I sign something for them other than my SQL output

(for example: if I put a string constant "Hello" on indicator "valor" I get "Hello" when calling the web service VI)

I suppose that the database connectivity kit is not supported when a VI is integrated with a web service VI. In my case, kit screws are inside the subVIs 'start', 'exec 2d' and 'stop' showed in the picture as an attachment.

Any idea?

Thank you


I'm using LabVIEW 2001 Wesley, but I solved my problem.

It was just a MySQL data source problem: I just had to add my info DB through C:\Windows\SysWOW64\odbcad32.exe.

Thank you

  • Reactive layouts: publish multiple Sites with conditional Builds and which connect

    I hope that someone can provide a simple solution to publish problems I've had with adapted presentations when you try to publish several sites with conditional builds. Essentially, I want to be able to have an index page that links to one of the two variants of the published sites that I called 'General' and 'specific '. When I click on the 'general' link I want to not open the site which was published with a conditional for all these subjects compilation labeled as 'general' and when I click on the 'link' want it to open the site which was published using a conditional version for 'specific '.

    Here are the steps I took to create sites and can't seem to get to bind correctly:

    Table of contents, topic Creation and tagging content

    1. Creates a Table of contents.
    2. Added 2 topics in the Table of contents. The first topic, I called "general" and the second issue I called, 'specific '.
    3. I then click with the right button on the "general" and selected subject Tag to build conditional apply. From there, I've created a new tag called "General".
    4. I repeated this process to create the specific tag, but do a right-click on the 'specific' theme and the creation of a new tag called "specific".

    Layouts reactive and edited the sites based on the conditional tags

    1. Created sensitive presentation using the standard layout and content generated without any conditional builds.
    2. Duplicated sensitive put in page and gave him the content of 'general' then it is generated using the conditional, "General" version If the finished publication published content has shown that the 'general' subject, as expected.
    3. I then repeated the same process for the specific content and content using the version parole, generated 'specific '. When over content published showed that the subject marked as 'specific' as expected.

    Added an Index page to the table of contents

    1. Created a new topic to serve as the launch page.
    2. Added a 'general' hyperlink called for the launch of the general "theme found in the general publishes from the resource manager.
    3. Added a hyperlink called 'specific' to the launch of the general "theme found in the specific issues from the resource manager.
    4. I then republish the sensitive standard layout site.

    From this point, it gets stuck and won't open properly published Web sites. I don't know why it won't launch hyperlinks correctly. Is there something I'm missing? Let me know if you do not want to see my files. I will be gladly their.

    OK, thanks a lot for the capture screen. They help more than you realize.

    So here's one of the biggest mistakes I think that you have done so far. You use the resource manager to link to published results. If it is technically possible to do, I'm pretty sure Adobe never planned for it to be used this way.

    It may help to think in terms of creation of food products. I have long considered as RoboHelp to be very much like working in my kitchen. All consumables (heading text in the headings, images, HTML pages, etc.) are just as raw ingredients. (Eggs, milk, flour, etc.). The places of storage (hard drive) it's like the pantry and the fridge. And RoboHelp provides facilities to easily combine ingredients to create the different recipes.

    This next bit will be somewhat exaggerated, but bear with me. Maybe you have one or more neighbors and all you want to share some common "ingredients". If you set the things where each of you have access to a wine cellar and a shared refrigerator. Maybe you do a Dutch sauce killer. You create it and place in the refrigerator, then your other participants have access through the common "fridge". This is exactly what the resource manager is intended to help.

    Now assume that you create something like cookies chocolate chip and you keep in the refrigerator. Well, that's fine, but you don't want to use cookies to chocolate chip already baked in a recipe that might call for cookie dough. But that's what happens when you take an exit and place in a place intended for raw ingredients. And you will see the strange behavior. Prepare for these cookies chemically changes them so that cookies already are significantly different from the dough used to create them. Similarly, you don't want to take one or more output files and reuse in a project source.

    So in your case, you run an index file and that fires events to produce the output. All should be well. But when you click on the links to open topics, topics are intended to show up more in the right panel. Think of the picture of how works of image on a TV. The moment that link you to something intended to fill the screen, he is forced into this smaller area on the right. If you end up with what you see in the last picture.

    I suggest the following steps.

    First, REMOVE your resource manager exits.

    REMOVE all links that can point here.

    Output records where people will consume copy your projects. (The web server)

    Then figure either the parent (.. /.. / somefolder/somefile.htm) path to other systems or the absolute path ( and to link the projects in this way.

    Sorry, but without seeing the installation of first hand, it is difficult to say what should be these paths.

    I hope this was helpful... Rick

  • Intermittent problem with IP addresses and internet connections dropped

    Once a day or so my PC (Win7) will not be able to access the internet. Connection just drops. I use DHCP for IP addresses.

    As far as I can see in the Event Viewer I get these types of errors "the address lease IP for the network card with network 0x406186808C4C address was rejected by the DHCP server (the DHCP server sent a DHCPNACK message)."

    My local network is simply: PC-online router (Cisco E1200)-online internet (modem Siemens SpeedStream 4100 DSL)

    "When this happens, we run ' ipconfig - release 'then' ipconfig - renew." This usually fixes the problem. Sometimes, this does not solve the problem, and we need also the modem power cycle. In a few minutes find us the internet connection. It's nice to have a manual correction, but we want to solve this problem to happen... as is the engine of our family crazy...

    The address LAN IP of the modem is set to

    The address LAN IP of the router is set to

    When things are running OK, I usually see it in the ' ipconfig-all the ' results: = IPv4 address (Preferred) [but the IP numbers change slightly] my understanding is that see "Present" in the result is a good thing (but I don't know why...).

    Any thoughts on what is happening? and how to permanently solve this problem?

    I'm also confused on IPv4 and IPv6. Should I be concerned with any information of IPv6 in the ipconfig-all the results?

    Thanks for the help

    Talked with the ISP (ATT). Zig - zag, you were on the problem. I had both modem and router set to DHCP mode... so I had some conflicts. The solution was to define the "bridge mode" dsl modem and configure the router to "PPPoE mode. Everything works now. Thanks for your help.

  • Problems with tutorial building a website with Web Premium CS4 – part 2: creating a local site

    I have problems with

    Building a website with Web Premium CS4 - part 2: creating a local site

    Since after taking all the steps in the tutorial and choosing Localhost from the menu to open the homepage of the Apache server in a web browser, IIS7 opens instead of the home page of the Apache server...

    I use Google Chrome as the default webbrowser...

    Looks like you have IIS as the Web server 'by default'.

    Try this http://localhost: 8080

    If that takes you to the Apache Web server, then you must set it as your default.


    News added: it is possible that both are listening on port 80 and IIS is a winner. To reconfigure IIS, open it and site web by default, you must change the site link. Http must be on port 8080.

    If Apache is already set to port 80, then you will not need to do anything else. I think that is fair. I don't know how to set up Apache to listen on port 80 if it is defined on port 8080. I do not have to look at.

    Make sure that you stop and restart your web services.

    This behavior can occur if the antivirus application blocking the app Store or changes due to some recent on the computer.

    I would suggest trying the following steps and check if it helps.

    Method 1:

    Make sure that updates are installed on your PC and that your antivirus program does not prevent the application from running. For more information about installing updates for your PC, see Windows Update: frequently asked questions.

    Method 2:

    Run 'Windows Apps Store' convenience store

    You must be logged in as an administrator in order to run the "Windows Store Apps" troubleshooter. This tool can automatically find and fix some issues with applications. It is available in English only, but will work in all languages. You can let automatically try to fix any problems found, or select what you want made repairs.

    Method 3:

    1. Press Windows + R logo
    2. Type wsreset.exe in the run window, and then press ENTER.

    Method 4:

    Define the Apps approved in third program Antivirus- If you have a third party AV program installed, check its settings to make sure that the app Store works is not changed to be approved. If the AV program has the app as unreliable, it will block and prevent opening the app.

  • Satellite Pro C650D - problems with the audio and game controllers


    I recently had problems with my microphone and speakers/headphones and game controllers.
    Sometimes the microphone stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Stakeholders sometimes still work when I connect headset.
    Some of the sounds are still coming through the speakers while some coming through the headphones.

    I have a usb game controller which also did not work everything properly.
    If I assign buttons in the program that they do not work in the game.

    All these devices are in Device Manager in a group that makes me think it's sort of annoying update doubtful that messes with them.

    Any body have similar problems or know what to do better?

    See you soon


    Can you please send some details on the laptop model and the system you are using?

    With regard to the issue of sound/mic:
    > The microphone sometimes stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Are you talking about internal microphone or external? This only happens using Skype?
    In your case I would test the microphone using different applications to make sure that is not a Skype related issue.

    > Yet sometimes the speakers work when I connect headset.
    I recommend this thread:

    The user has had a similar problem, but this phenomenon was linked to the Realtek HD Audio Manager settings.
    She wrote:
    + In the upper right corner, there is a small yellow folder called "Connector settings" in my version. +
    + There, finally I could re-enable the setting "enable popup dialog box, when the unit is plugged. +

    + So now when I plug an external speaker or headphones, it appears, and I select the option "helmet" (instead of "line-in"), and then the sound only through the headphones/ext.speaker.+

    Regarding the game controller:
    > I have a usb game controller which also did not work everything properly.
    > If I attribute buttons in the program, they do not work in the game.
    I put t think its problem of laptop in my opinion, you must make sure that the controller is compatible with the games you play and also recommended to check some info provided by the manufacturer of the game controller.

  • Problems with wifi, bluetooth and gps in my iphone after updating iOS 6

    After that the last iOS 9.3 update my iphone 6 has problems with wifi, bluetooth and gps. Now, my wifi connection is slower and falls easily on a short distance. My bluetooth does the same. But the biggest problem is the GPS on my phone. I tried Island:

    -By doing a reset network

    -Do a reset total and restore my phone

    -To restart my phone twice.

    -Audit and third-party applications unnistalling

    Nothing works. I was in the apple store where they checked my phone and they say everything is ok with the phone. I'm not crazy, and I know when something does not work correctly. Also, I think it's iOS 9.3 update a reaponsible for my phone issues.

    Please fix bugs fast.

    Having the same exact problems since the upgrade. In addition, battery drains very quickly now, and sometimes the phone becomes very hot. It took to the Genius Bar and they told me everything was normal in the diagnostic tests. Restored, restarting, etc., and always the same problems. GPS locates me, but then don't follow my movement at all and told to go outside as the gps is not detected even if I am outside. Bluetooth connection to the car and watch grave intermittently.

  • Problems with my mouse, and have not been able to find a solution to the research on various forums.

    Original title: mouse problems

    I have problems with my mouse and have not been able to find a solution to the research on various forums. Here are the symptoms:

    1. you must click several times to get the menus to open. Sometimes they are not just and sometimes they open with a single click flash but do not stick until I clicked several times.

    2 several times the menu drop down and seem to become transparent (not in looks) because when I click on something on the menu, he actually selects everything that is behind the menu drop down. For example, if I'm in powerpoint and you select an item in edit mode, it might work and here again he can just select the slideview behind the menu and expand. Or well, if I'm on a Web site, such as Facebook, and I chose to close the session, rather than enable the disconnection of the key, he chooses some ad is behind the part of the menu and redirects the page of this Web site.

    3. when I try to select a Word, words or sections as paragraphs, it performs several different things: continually select as soon as I let go of the mouse button, the jumps of color selection in another part of the document, or deselects the part of the text before I even let go of the mouse button.

    Here is what I tried:

    1. I had originally a usb wireless mouse. I changed the batteries and then got a new. Now I use a wired mouse.

    2 make sure all updates for Windows and Office 2010 are updated.

    3 has tried to update the drivers mouse, says that it is up-to-date. He restored, did not work. Uninstalled and restarted.

    4 Ran Windows Security Essential and Malwarebytes - found nothing.

    5. ensure that all the Toshiba updates were up-to-date.

    I don't know how the word this issue properly in order to find information about it. Everything I typed in search engines brings me other problems unrelated to this one.

    I am running W7 64 x Home Premium SP1, SP2 MS 2010 with a mouse Dell; Toshiba Satellite C655

    Well I have stumbled on the fix... looks like there was a problem with the HID-compliant mouse. The convenience store hardware detected and solved the problem. Everything seems to work properly again.

  • Problem with Adobe Flash and RealPlayer (and maybe also this old man)

    Dear Sir.

    I had problems with Firefox as my browser and on the Adobe site answer that it is said:

    If you have RealPlayer installed on your system, please disable recording of the RealPlayer browser plug-ins.

    1. Launch RealPlayer
    2. Click on the RealPlayer icon in the upper left of the window and choose Preferences.
    3. Choose the download and registration from the left panel
    4. Uncheck "allow Web downloading & recording for these browsers installed.
    5. Click OK and close RealPlayer
    6. Restart Firefox

    The only problem now is that I downloaded the latest version of RealPlayer, following your instructions above, I can make 1, 2, and then I have a problem that in the left panel, it is not "allow the Web download & recording for these installed browsers. It offers is:

    General - playback settings

    Internet - proxy, transport network




    Content - Types of media

    I initially needed to do this (i.e. uncheck etc.) as Firefox froze. At the moment I don't know if it freezes again. I just downloaded the latest version of RealPlayer and tried to follow your previous instructions.

    I'm sorry to take your time again. I am a former user of the computer and not really with it. Can you help me please?

    How can I return to 4.0 3.6 I've never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.

    Then you can install the latest version of Firefox 3.6 available to - it will automatically use your favorite courses, passwords etc.

    I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.

  • HP 15 laptop: problem with the touchpad and the key "stuck."

    Last weekend, I have an irritating problem with my HP 15 laptop. Bought two years ago and upgrades to Windows 10 a year ago.
    First of all, my touchpad started to not work properly. It "freezes" and I can't use it until I click the ESC key, but it doesn't last and "freezes" again a few seconds later. Then, everytime I open a window where there is a text box (Start menu, edge browser, Control Panel, etc.), the number 5 is entered automatically and permanently, as if the button 5 has been blocked. I did a quick check and button 5 do not seem physically stuck.
    Yesterday, I restored the system to the factory settings, so I'm back to 8.1 for Windows and then upgraded to Windows 10. Everything seems to work fine, but this morning, the problem was back. Is there something I can do? What is the problem caused by Windows 10 or the computer? Should I restore it to Windows 8.1? Everything worked great til last weekend, I don't know what that was.
    Thank you in advance for your help!

    Welcome to the HP support community @gouch3.

    I understand that you have a problem with the keyboard and the touchpad on your laptop from HP 15.

    Have you tried to use a keyboard external and mouse at all?

    Have you tried to go to Safe Mode to see if the problems persist in there?

    Have you tried to perform a material or forced reset Reset?

    Did you do a test of material?

    Have you updated your drivers?

    It could be a driver problem to be able to look at that for you, I need your model number. I wish I could give you an answer or not, but at this point without the troubleshooting results and the model number, it is difficult for me to say.

    I can say that if everything works in point 8.1 of Windows without problem, the driver TROUBLESHOOTING is a great place to start. Please try to follow these steps for the keyboard and the touchpad of troubleshooting:

    • Beginning
    • Search for Device Manager
    • Search results, open Device Manager.
    • Click on display
    • Show hidden devices.
    • Click the arrow next to keyboards.
    • Right click on the name of the keyboard device.
    • Select uninstall.
    • Continue deleting the names of devices in the category keyboards until the feature of all the names have been uninstalled.
    • Restart the laptop twice.


    • Type of research, "Device Manager."
    • Click on Device Manager,
    • Expand mice and other pointing devices.
    • Right click on the TouchPad,
    • Click on uninstall.
    • Restart the computer laptop twice,
    • Reinstall the TouchPad card.

    I found a document of troubleshooting for you to try also called Portable keyboard troubleshooting. Please be sure to follow the steps described in this document.

    The best document I have for TouchPad problems is the use and troubleshooting of the TouchPad and ClickPad document. 

    Here is a link to the HP Support Assistant, if you need it. Just download and run the application and it will help with the software and drivers that need to put up-to-date.
