• How to close a database connection in the new browser

  Hi @ all,

  with the new object browser, it is easy to connect to a database with the methods 'ConnectDataStore' or 'ConnectDataStoreByParameter '.

  But how the connection can be closed?

  In an AsamOds environment, it is important to close the connection, because a part of the environment (the so-called ORB) 'hiding' some data (in the ActiveObjectMap). This "cache" is cleaned by closing the connection. So, the problem is that without the ability to close a connection, the cache grow upward (and in how the Orb ist becomes unstable and crashes after a while).

  Thanks for reading

  Greetings from the Germany

  Contur

  Hi Contur,

  the new ASAM-ODS API doesn't have an explicit close method. A store (and here the connection held by this store) will be automatically closed when all references to this store is closed - which translates into VBS to nothingness. The easiest thing is the store itself:

  Dim myStore: set myStore = Navigator.ConnectDataStore ("ASAM pass fail analysis Example")

  Define myStore = Nothing

  In the case your script any other helds refers to this store, for example the results of a query or a certain element, that you must set to nothing as well

  Dim myStore: set myStore = Navigator.ConnectDataStore ("ASAM pass fail analysis Example")

  protected myRootElements: set myRootElements = myStore.RootElements
  Set myRootElements = Nothing

  Define myStore = Nothing

• How can I open a connection of default APDUS on the frame of the SIM card?

  Hello world

  I'm trying to run a basic command on my SIM card in my BlackBerry device (select MainFile). But I am stuck because even if I build my APDU command I still manage to open a conection APDU to the default service which will give me access to this directive.

  To open an APDU connection, you must spend aid (Application IdeDentifier sim card) parameter to the APDUConnection constructor but apparently there is no HELP for built-in applications, apparently AIDS is created only for the demand for custom sim card.

  Does someone could help out me?

  Thanks in advance.

  The set of BlackBerry API allows you to communicate with a custom application installed on a SIM card.  It does allow you direct access to any of the SIM card.

• ADF: Management graciously JDBC connection errors?

  Hi gang
  
  We have a use case view a specific web page when the JDBC connection falls on our ADF application, specifically the following error:
  
  oracle.jbo.DMLException: Houston-26061: error when opening JDBC connection.
  
  I did research on solutions to this and came up with a solution of proximity to place the following entry in the application's web.xml file:

  <error-page>
    <exception-type>oracle.jbo.DMLException</exception-type>
    <location>/MyErrorPage.jsp</location>
  </error-page>

  This works very well, but is a blunt mechanism because it captures all the DMLExceptions which includes failures of insert/update / delete, as well as the fall of JDBC connection on the.
  
  Everybody comes back with a better solution for the treatment of the JDBC connection drop-outs?
  
  Thank you and best regards,
  
  CM.
  
  PS. (JDev 11g build 5188, ADF BC + ADF Faces RC)

  Hi Chris,

  Caveat: I've not tested this - just think aloud at this stage before my departure to catch a train...

  Could you do that in a custom class of DCErrorHandlerImpl? I don't know if you are authorized to make a redirect in reportException or not - I'll have to try that.

• Error: open the-1073807300, probably because of several sessions of VISA. How to close all?

  I have a simple vi that takes a reading of a picoammeter, using the instrument-specific sub-vis. I guess I'm the new opening VISA sessions each time I run it. Recently I get the 1073807300 error: not enough system resources to perform the necessary memory allocation. I tried to add a close command, but I still think I have VISA open sessions.

  Any suggestions on how to close will be much appreciated!

  Is attached to the original vi (picoamm_1) and initialization void / vi if it can help.

  It's all wrong. First of all, you don't have control of IVI resource name. It's the wrong class. Right-click on the entry of the initialize function and select "Create Control". Second, you don't close the IVI sessions because you have wired it correctly. This shift register is just ridiculous. Do NOT wire your control in the loop and return. You want the reference to the session of the function of the loop of wire at the Close function which is in the driver. As it is to wire the session, the loop will be autoindex in a table. Just right click on the exit tunnel and select 'disable indexing. "

• When I open a document to read like an instruction how to close it.

  I need to know when I open a document on the line as a statement how to close the document and return to the previous screen? I use windows 8.

  If you read the document using a Store Windows app, there is no need to close. Just switch to a different app (for example by pressing the Windows of your keyboard key to access the boot screen, then selecting the next application that you want to use).

  If you close the app and then slide down (or drag if you use touch) from the top to the bottom of the screen. Pressing Alt + F4 will also work.

  Please see:

  http://windows.microsoft.com/en-gb/windows-8/how-close-app .

  If you use a desktop application then the X in the upper right corner of the application should still work the same way as it did in previous versions of Windows.

• How to close an open path

  Hello

  seems info on how to close an open path in a more simple way in illustrator is rare, that I did not come across any.

  How do we?

  

  How do you want to close? You select the two end points and Ctl - J will do the work for you, but only if you want a straight path between two points. This can be simple, but to choose the best way depends on your design and what you want to achieve, that's why there are no simple answers.

• How to operate with several connections open for VCs (Connect-VIServer).

  Hello:

  I know that I can open multiple connections to VCs (Connect-VIServer), but do not really understand how to run with them...

  How can I speak in VC1 for a single operation and after that VC2 to another without closing the connection in VC1?  I might need to do this several times in my script...

  Any help and simple example will be really appreciated.

  Thank you

  qwert

  The cmdlet Connect-VIServer of PowerCLU 4u1 leave takes supported several open sessions.

  The sessions are stored in a table called $defaultVIServers.

  If you need restore an open session, you can use the entry for this server in the array and then use the SessionId property to make this session open session / by default (which is stored in the variable $defaultVIServer).

  Something like that

  Connect-VIServer -Server VC1
  Connect-VIServer -Server VC2
  # Show the sessions and their properties
  $defaultVIServers | Select *
  
  # Open the session to VC1
  Connect-VIServer -Session $defaultVIServers[0].SessionId
  
  # Open the session to VC2
  Connect-VIServer -Session $defaultVIServers[1].SessionId
  
  # The open session
  $defaultVIServer

• How to prevent a TCP connection that is closed when the VI who opened it terminated.

  Hello everyone.

  I'm developing an application based on the servers and clients communicate through TCP in LabVIEW 2012.

  When the Server/client opens a TCP connection, it starts an asynchronosly running "Connection Manager", to which connection reference that takes so all communication happening. It all works very well.

  -J' have a situation where a client connection manager can be informed of another 'new' server. I would like to open the connection (to see if it is still valid) and then pass this reference of connection to the main client code to spawn a new connection manager. This avoids lock me up the Client code main with an ish timeout if the 'new' server does not really accept connections.

  The problem is that if the connection manager that opens the connection to the 'new' server is stopped, then it seems to destroy the reference he opened. This means that the other connection manager that has been happily character with the 'new' server has closed TCP communications (I get an error code 1 on an entry).

  I created an example to illustrate the issue which should be used as follows:

  1 run server.vi - he will listen for a connection on the specified port on his comics.

  2. run Launcher.vi CH - it will open a connection to the server and pass the TCP reference to an instance of connection Handler.vi, which he started.

  3. the connection manager needs to send data to the server

  4. stop the Launcher.vi CH

  5. the will of Handler.vi connection error.

  Any suggestion would be appreciated.

  See you soon

  John

  Do not perform the opening and closing of the TCP connection in Subvi. Do this to master VI.

• How to close the open window by Exec VI system automatically?

  Hello

  I use the Exec VI system to launch an exe that is built from a LabVIEW program. Operational system Exec VI, the window out of file exe and stays there even after all the tasks are completed. I have to close it manually each time. Anyone here know how to close the window of the exe file automatically when it's done?

  Thank you

  Jean

  If I understand the question you add a node to call at the end of your application to exit. As it runs as a stand-alone application or in LabVIEW there will be out or stop the execution. I have attached the VI that I use in my applications.
