database connection status indicator

I want to put something on the front of my program which will indicate the status of database connection. I think to ask at the tables in the list (it should be displayed), if the connection is good, it shows error. I tried and I think it works very well, but I don't know if it's the right way to do it, there may be better ways there, could someone point out he for me?

Best regards

You certainly don't want to open and close the connection. Maybe it will fail, but the 'real' connection is good. Maybe the real one has failed but this other works opening and closing. This could happen if the server has the maximum number of connections.

Your connection is little go far?

A simple method to check the connection just must have a loop that executes periodically a meaningless statement.

  • Calling stored procedures with parameters with the database connectivity Toolkit

    Hi all

    I'm new to the forum and struggling to find a solution to a particular problem I have in this respect, using the LabVIEW Database Connectivity Toolkit on a project, I am currently working on my work.  I have a database in which I tables and stored procedures with parameters.  Some of these stored procedures have input, output and return parameters.

    I tried to follow this example, but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument

    Such a stored procedure I am working on the implementation is named "dbo.getAllowablePNs", running "SELECT * from DeviceType" (DeviceType is the table).  In this case, it requires no input parameter, it has an output parameter that generates the table [cluster] and has a return parameter that returns an integer value (status code for execution) to show if an error occurred.  The DeviceType table has 3 columns; ID (PK, int not null), PN (nvarchar ((15), null) and NumMACAddresses (int, null).)  I have surpassed many examples and I talk to the support OR try to implement this and similar procedures stored in LabVIEW but have not been successful.  I am able to connect to the database with the VI of open connection without error, but spin in some confusion as a result of this step.  I then try to use the VI of parameter query create to call the stored procedure and set the parameters.  I guess I would then use the Set parameter value for each parameter that is connected to the entry of parameters on the previous query with parameters VI VI?  I am also having some confusion during and after these steps as well.  I would greatly appreciate advice or suggestions that anyone could have in this situation because I am not a SQL expert.  Also, I would be happy to provide more information that might be useful.

    Kind regards

    Jon

    Here's what I use to do this.  I think I had to change him create parameterized query VI for him to work.  There is a post on the forum about this somewhere.

  • Reading large data using the database connectivity

    Hello

    I use the Labview database connectivity toolkit to connect to my database sqlitev3 (I'm using ODBC). I just have to connect to the database (using the block of open_connection) and read all the values inside (using the select_data block). The problem is that my database is huge (about 2 GB), and I get this error:

    .

    What should I do? It seems that he reads the data in the memory and it doesn't have enough space for it. When I read the data I want to write to a file.

    Read it in pieces. Write each piece to the file, and then repeat with the next segment. Try to read and process all data in one shot is not very practical and you found out will not work.

  • How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

    Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

    Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.

  • Problem installation database connectivity Kit

    My company manufactures in several factories around the world.  I have a problem in China and that you want to debug, and because the code is distributed in the form of exe, it is a problem.  My approach was to install a trial license of 30 days of LV2010 SP1, intend to withdraw when debugging is done.  So far, so good.  The problem is that the application requires the database connectivity Toolkit.  I downloaded a copy and tried to install.  It says it can't install because LV2010 is not installed.  Is it because of the eval license?

    If I wanted to rewrite hundreds of applications running, I could do that, but what I want is to install the DB Toolkit for a bit of troubleshooting.

    If NEITHER would alter the conditions on their license server, I would not have these problems.

  • Database connectivity broken vi Toolkit

    Hi all

    I upgraded from LV 8.5 to 8.6 (windows XP platform) a couple of weeks and have had no problems until today when all of sudden my vi toolkit database is coming from broken, with: "one or more of the inputs needed for this function are not wired or are wired incorrectly. Display the context-sensitive Help window to see what should be the connections to this function. ' Mistakes however is not the case on all my vi using the objects in the Toolbox.

    Measures taken so far without success:

    1 mass compilation of my vi

    2 mass compilation of database Toolbox

    3 re install Database Resource Kit

    4 mass compile the directory vi.lib

    5 in the old knowladge base article Document ID: 2RO7J544, assured the latest microsoft MDAC is installed.

    Any help is appreciated as we use this receptive toolkit.

    Hi Chris,

    Thanks for the reply and I hope that your well.

    I need to try to understand something, when you say that the LabVIEW 8.6 upgrade have you improved the Toolbox?

    Toolkit LabVIEW Database Connectivity 1.0.2 is for LabVIEW 8.6. If, on the other hand your trying to use LabVIEW 8.6 with DC Toolkit 1.0.1 so I think that they are not officially compatible. However, these links may be of interest knowledge base: (after all, they are just screws). However, to say this - if you read the Readme for the new toolkit, that many things have changed for LabVIEW 8.6 - so becareful.

    You will have to manually copy all the files in one version of LabVIEW to another. Use the following instructions to achieve:

    1. Install the database connectivity toolset to the version of LabVIEW, say X.
    2. Copy the following files/directories in the directories right in the latest version of LabVIEW, say Y.
      • Copy the data directory from \LabVIEW X\vi.lib\addons\ to \LabVIEW Y\vi.lib\addons\
      • Copy the file database.llb \LabVIEW X\project\ to \LabVIEW Y\project\
      • Copy the data directory from \LabVIEW X\examples\ to \LabVIEW Y\examples\

    I would also check that you have installed the Toolkit for LabVIEW 8.6 - toolkits are now specific for labVIEW 8.6. Then maybe try to reinstall and the Toolbox for LV8.6.

    Hope this helps and please let me know (Please specify a little more).

  • Error 1068: Unknown connection status: the service dependency or groups could start

    Hi all

    I ave a problem with Vista service pack 2 running on Sony viao with the network. I have access to the internet, but my connection icon has a red X on it with the message "unknown connection status: the dependency service or group could not start". I did my homework to browse all the threads and have performed all of THE following conditions, but the problem persists.

    1. in the course of execution sys check through sfc/scannow

    2. reset TCP/IP through 1. netsh winsock reset 2. netsh int ip reset

    3. verification of all services such as the services in the list of networks and knowledge of network locations.

    However the problem persists. I cannot forget to mention that the list of Network Services and network location awareness not start I get the same error when I try to start them. I checked all the services above is dependent on and they are started and set to automatic.

    Is there anything else I can do to solve this problem other than the system of recovery or reinstallation? I have some stuff on my laptop that even if I save them I have given will be lost. for example the accounting software with its data, software for which I don't have the disk to re - install and the data in them cannot be saved on a server running. To make the story short, I really want to avoid recovery on the option of resettlement

    As I said, I have access to the internet, but the mere fact that this problem is there, its that bothers me and I don't want to run bigger problems later

    Any help would be greatly appreciated

    Thanks in advance

    Hi IMOMDS,

    1. don't you make changes before the show?
    2. have you checked if the network connections and support TCP/IP NetBIOS services are started?

    Try these steps and check the result.
    Step 1: Virus scanner online
    a. visit http://onecare.live.com/site/en-us/center/whatsnew.htm
    b. click Full Service scan and complete the scan.
    c. check the difference.

    Note: Use your favorite security software to search for viruses or malware on the computer and remove it.

    Step 2: If the problem persists, restore the computer to an earlier time when it was working fine
    a. see what is system restore?
    b. Once you have restored the computer, check if the problem persists.

    Visit our Microsoft answers feedback Forum and let us know what you think.

  • Connection status: unknown. The dependency service or group was able to start.

    Greetings!  I have a year old Dell Inspiron.  Everything worked fine last night, but when I woke today I couldn't connect to the internet.  When I put the cursor on the network icon, it says "connection status: unknown."  The dependency service or group was able to start. "My Windows Firewall is also disabled and I can't activate it automatically or manually.  In addition, the Windows Diagnostic tool cannot be turned on, and whenever I try to activate the Diagnostic Policy Service it also can not be done. It says "error 5: access is denied" when I try to turn it on manually.

    My antivirus (Avira) software is fully up to date from last night.  I even took it into Best Buy and they did a diagnostic test to ensure that a virus is not the cause.  The guy there said it was a software problem.  I tried resetting TCP/IP (netsh winsock reset) without success.  I also tried sfc/scannow in safe mode and windows without success.  Are there other options?

    Thanks in advance.
