  • Determine Last Modification Datetime for an Azure Table

    - by embeddedprogrammer
    I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes. My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique: SELECT OBJECT_NAME(OBJECT_ID) as tableName, last_user_update as lastUpdate FROM mydb.sys.dm_db_index_usage_stats This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?

  • Where does abort() and terminate() "live"?

    - by user325016
    Regarding the terminate handler, As i understand it, when something bad happens in code, for example when we dont catch an exception, terminate() is called, which in turn calls abort() set_terminate(my_function) allows us to get terminate() to call a user specified function my_terminate. my question is: where do these functions "live" they don't seem to be a part of the language, but work as if they are present in every single cpp file, without having to include any header file.

  • Check for active connection in NHibernate

    - by Dofs
    I have a system with a few different databases, and I would like to check if a certain database is down, and if so display a message to the user. Is it possible in NHibernate to check if there is an active connection to the database, without having to request data and then catch the exception?

  • Is there a way to bypass the jQuery error handler?

    - by oravecz
    If my Ajax call returns a successful result, but while processing the result I cause an exception, the error handler fires. This seems counter intuitive to me as I think the error handler should only fire when an error occurs as a result of making the Ajax call or via a server-side error. I am trying to use the Ajax function in a unit test so I would like to tell the difference between the two different failure scenarios.

  • Why does the Java compiler complain about a local variable not having been initialized here?

    - by pele
    int a = 1, b; if(a > 0) b = 1; if(a <= 0) b = 2; System.out.println(b); If I run this, I receive: Exception in thread "main" java.lang.Error: Unresolved compilation problem: The local variable b may not have been initialized at Broom.main(Broom.java:9) I know that the local variables are not initialized and is your duty to do this, but in this case, the first if doesn't initialize the variable?

  • RIM blackberry Record 3GP video

    - by pankaj_shukla
    Hi All, I am writing an application that can record a 3GP video. I have tried both MMAPI and Invoke API. But have following issues. Using MMAPI: 1. When I record to stream, It records video in RIMM streaming format. when I try to play this video player gives error "Unsupported media format.". 2. When I record to a file. It will create a file of size 0. Using Invoke API: 1. In MMS mode it does not allow to record a video more than 30 seconds. 2. In Normal mode size of the file is very large. 3. Once I invoke camera application I do not have any control on application. Here is my source code: _player = javax.microedition.media.Manager .createPlayer("capture://video?encoding=video/3gpp&mode=mms"); // I have tried every encoding returns from System.getProperty("video.encodings") method _player.realize(); _videoControl = (VideoControl) _player.getControl("VideoControl"); _recordControl = (RecordControl) _player.getControl("RecordControl"); _volumeControl = (VolumeControl) _player.getControl("VolumeControl"); String videoPath = System.getProperty("fileconn.dir.videos"); if (videoPath == null) { videoPath = "file:///store/home/user/videos/"; } _recordControl.setRecordLocation(videoPath + "RecordedVideo.3gp"); _player.addPlayerListener(this); Field videoField = (Field) _videoControl.initDisplayMode( VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field"); _videoControl.setVisible(true); add(videoField); _player.start(); ON start menu item Selection: try { _recordControl.startRecord(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } On stop menuItem selection: try { _recordControl.commit(); } catch (Exception e) { _player.close(); showAlert(e.getClass() + " " + e.getMessage()); } Please let me if I am doing something wrong. Thanks, Pankaj

  • Parsing line with delimiter in Python

    - by neversaint
    I have lines of data which I want to parse. The data looks like this: a score=216 expect=1.05e-06 a score=180 expect=0.0394 What I want to do is to have a subroutine that parse them and return 2 values (score and expect) for each line. However this function of mine doesn't seem to work: def scoreEvalFromMaf(mafLines): for word in mafLines[0]: if word.startswith("score="): theScore = word.split('=')[1] theEval = word.split('=')[2] return [theScore, theEval] raise Exception("encountered an alignment without a score") Please advice what's the right way to do it?

  • Help with ejb 3, weblogic and spring.

    - by berserkpi
    So,hi there. I've created a simple EJB3 test project, the code is simple: @Stateless @Remote( { ISumaSimple.class }) public class SumaSimpleBean implements ISumaSimple { /** * Default constructor. */ public SumaSimpleBean() { // TODO Auto-generated constructor stub } @Override public int sumar(int a, int b) { // TODO Auto-generated method stub return a + b; } } public interface ISumaSimple { public int sumar(int a, int b); } Ok, my client is a stand alone spring aplication which configuration is: <bean id="sumaSimpleServicio" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiEnvironment"> <props> <prop key="java.naming.factory.initial"> org.apache.openejb.client.RemoteInitialContextFactory </prop> <prop key="java.naming.provider.url"> ejbd://localhost:4201 </prop> </props> </property> <property name="jndiName" value="SumaSimpleBeanRemote" /> </bean> <bean id="clienteService" class="qtx.cliente.simple.ClienteService"> <property name="sumaSimpleServicio" ref="sumaSimpleServicio"></property> </bean> All worked smoothly, but then I tried deploying using weblogic 10.3, I just changed these values: weblogic.jndi.WLInitialContextFactory t3://localhost:7010 In weblogic jndi tree my ejb is under: SimpleEJB3SimpleEJB_jarSumaSimple3_ISumaSimple Of course I added wlclient.jar to my spring client classpath. I think I am missing something in weblogic case, but dunno. My spring client is throwing this exception: Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [qtx.ejb.simple._SumaSimple3_gwze0z_ISumaSimpleIntf_Stub] to required type [qtx.servicio.simple.ISumaSimple] for property 'sumaSimpleServicio'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [qtx.ejb.simple._SumaSimple3_gwze0z_ISumaSimpleIntf_Stub] to required type [qtx.servicio.simple.ISumaSimple] for property 'sumaSimpleServicio': no matching editors or conversion strategy found at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:391) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.convertForProperty(AbstractAutowireCapableBeanFactory.java:1288) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1249) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1010) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:472) ... 14 more Caused by: java.lang.IllegalArgumentException: Cannot convert value of type [qtx.ejb.simple._SumaSimple3_gwze0z_ISumaSimpleIntf_Stub] to required type [qtx.servicio.simple.ISumaSimple] for property 'sumaSimpleServicio': no matching editors or conversion strategy found at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:219) at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:138) at org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:386) ... 18 more Any help would be appreciated.

  • Java return to position N in call stack.

    - by Finbarr
    Using the return keyword in Java code will return execution to the last piece of calling code in the call stack. If object foo calls baz.bar(), the return keyword in the bar method will continue code execution in foo. Let's say I have object foo that calls foofoo that calls foofoofoo in the above scenario, and foofoofoo calls baz.bar(). Is there anyway in Java to use the return keyword, or something else, so that the code in the bar method can return all the way back up to foo? (WITHOUT THROWING AN EXCEPTION)
