Need to call ObjectListField.setSelectedIndex (int) with holding EventLock

Hello

first of all I'm new here and I want to thank the forum a LOT as he already has helped me by just searching. Now I am facing a problem where I can't fiond one equivalent to the.

I have read through several totorials how manipulate GUI (EventThread) and also through several topics on this site, so the idea of how doing this is familiar to me.

I use a third-party library that is implemented with an Observer pattern to send events. On obtaining a particular event, I have to call the UI thread and display information on a screen changed.

Now I do the error familiar "UIEngine" accessible without holding the lock of the event inside the invokeLater/invokeAndWait. How can this happen? Is it possible that it depends on the third my library event thread since it's the thread that calls?

However, I found that with the help of snchronized (Application.getEventLock) {...}, no error is thrown, but ObjectListField.setSelectedIndex (int) is not working properly. It actually changes the index but do not display the change on the screen. So is it possible that changes in the return buffer, but not in the display buffer? Also tried to invalidate the entire list or only the selected item and was updated with

UiApplication.getUiApplication () .updateDisplay (). Without success.

Any suggestion would be appreciated. Thanks in advance.

  • C# Oracle.DataAccess calling a stored procedure with a date parameter throws formatexception

    C# Oracle.DataAccess CommandType.StoredProcedure is OracleDbType. Date

    I can't get my code to call an oracle procedure that has an order date.

    I receive a System.FormatException occurred in Oracle.DataAccess.dll

    I tried to assign the param. Value = DateTime and also tried assigning as a string formatted with no luck.

    What is the magic formula, I need to call this function?

    Here is a code snippet:

    OracleCommand cmd = new OracleCommand();

    cmd connection group appConn;.

    cmd.CommandText = "mypackage.myprocedure";

    cmd.CommandType = CommandType.StoredProcedure;

    Param = new OracleParameter ("iDateParamter", OracleDbType.Date, ParameterDirection.Input);

    Param. Value = "August 31, 2015."

    Here are other formats I' tried... ved param. Value = myDateValue.ToString ("dd - MMM-yyyy"). ToUpper(); (/ / "MM/dd/yyyy"); 'YYYY-MM-dd'); "MM-dd-yyyy");

    cmd. Parameters.Add (param);

                BindByName. cmd = true;

                cmd ExecuteNonQuery());

    Shame on me..., you can close this message

    It was not for the error on my date field, I had another parameter that has been attributed to a string instead of an integer.

    For the record, this has worked well for me:

    Param = new OracleParameter ("iActvyPerDate", OracleDbType.Date, ParameterDirection.Input);

    Param. Value = li. ActvyPerDate.ToString ("dd-MMM-yyyy"). ToUpper();

    User, because the two tables have a relationship, we call matter detail relationship, you can use a link view defining the relationship, and the framework will be the selection detail for you automatically.

    The next thing is that you can not put a table in a column of a table. This is not supported by the table component. You can use a picture of the tree for this, or tables cascading as I show in JDeveloper 11.1.2.1: cascade Tables | JDev & ADF Goodies

  • I need to change the default 'open with' Bridge of photoshop to photoshop CC 2015.  How do I do that?

    I need to change the default 'open with' Bridge of photoshop to photoshop CC 2015.  How do I do that?

    Hi karen,.

    It can get a bit tangled. Bridge delay normally to some think the Finder is the default, and every OS has its own way for you to tell the OS what you say should be the default value. On Mac, it's in the file information dialog box. I think that Windows called something like properties. You can change an extension to open all files with an application in your operating system first, restart Bridge and see if she pays tribute to this choice by double clicking on a file and observing that it opens the right version of PS. normally, it will be. (By default) must also appear after this choice in the list open with contextual (right click on the file you want to open, select open with and find the name of the application in the list).

    If this does not work, you will need to manually choose your file association for the extension of the list next to him in the Bridge preferences > File Associations. Which is normally necessary only when you want to override the default choice of your OS System. For example, maybe you want to bridge to open in PS JPEG files when you double-click it in Bridge, but if you double-click on a file in the Finder/Explorer JPEG, you want to open with Viewer of this system. It will not say it is (by default) in the pop-up list more, but bridge will honor your file associated with the choice of your system.

  • OSB11g - I need to call a service at intervals of time-any option?

    Hey Geeks,

    I need to call a service at regular intervals - offers OSB the same?

    Here's a way to do it, not very sophisticated but it will work.
    1 put the infinite attempts on the JMS queue (no limit of attempts) and significant a delay between attempts (you may need to tweak it based on performance tests but 5 minutes seems a fair value).
    2. using the factory of XA connections to access the queue for messages can be cancelled
    3. in the Proxy service that reads messages from the queue, first make a call for audit of system B in the request pipeline status, if the queue length is less than the recommended limit and then route the message to the system B. If the queue length is more than limit and you want to delay the sending of the message, then triggers an error in the Service of the Proxy and the message will be restored in the JMS queue and retried after 5 minutes (or any value that you put in the new attempt to delay the creation of the queue).
    4. in addition, since there will be cases where messages are queued to the top, and if you do not want to try more than one message at a time, then set a work with a wire constraint Manager Max to the desired number of threads on the JMS Proxy and also reduce the Maximum Messages per setting of session Connection Factory default value of 10 to 1.

    Another approach would be to create a planner to call the process.
    1. create a planner for the BSO
    See here:
    http://blogs.Oracle.com/jamesbayer/entry/weblogic_scheduling_a_polling
    3. create a simple Java class that reads the message from the JMS queue synchronously
    2 when the Scheduler calls the OSB Proxy service, check the queue length in system B by calling the web service of State of system B.
    3. If the length of the queue is within the limit then make a legend of Java to the synchronous consumer class and retrieves the message from the Proxy of OSB
    4 to get the message to system B

    I play world of warcraft and use a program called ventrilo to talk with other players. the problem I have is my game sounds can be heard.
    Vista makes my headphones 'speakers', so when I use a program called ventrilo to talk with other players in my game sounds are heard through ventrilo. My headset is a headset/microphone generic plug-and-play.

    Hey CassiusVa,

    Welcome to the Microsoft Answers Forum!

    Since when are you facing the issue?

    Can I know the version of Ventrilo you use on your computer?

    It may be that World of Warcraft focuses on your audio hardware.  You can try to reduce the audio settings in WoW to see if this makes the use of Ventrilo better.  It may also be a driver problem.  I would check to make sure that you have the latest drivers for your audio device.

    Use the following steps to ensure that the audio drivers are up to date.

    1. connect to the Internet.

    2. click on start and enter the Device Manager in the start search field.

    3. click on the plus sign next to sound, video and game controllers.

    4. right click on the name of the sound material and select software update of the driver...

    5. click on search automatically for a driver updated and wait for Windows to update the driver software.

    6 Windows checks a remote Web site to see if the update of the driver software is available.

    * If an update is available, let Windows install the update.

    * If an update is not available, proceed to the next step.

    7. once the update is successfully installed, test the microphone.

    Please follow the steps below and check if you still have questions echo.

    Go into Ventrilo Setup and select mixer for the sound card, which will be the audio input (as determined by the "Input device" option) device. This will populate the Mux and line options. Normally it would take only a Mux. It is possible that you may have many options of the line. Go ahead and select "Microphone" or anything that is appropriate for the input line and then click OK.

    This should solve the problem.

    Please note that you select mixer, mux and line will allow the "Hardware Volume" slider This gives you the control hardware on the audio input signal and is the best way to control how strong you are. Setting the cursor to halfway better seems to work for most people, but it will be hardware and system load.

    You can also browse the links for more information on ventrilo and try to contact them if the problem persists.
