[ "How to run clickHandlers on buttons moved from main view component to header bar", "I've used JRab's example here http://supportforums.blackberry.com/t5/Tablet-OS-SDK-for-Adobe-AIR/App-specific-system-menu/td-p/693... to add a header menu to my app. What I'm having trouble with is executing my functions from the header mennu. For example, my firstView is appHome.mxml. It instantiates a Canvas object that has an erase(). There is a button in appHope.mxml that executes the erase() on the Canvas instance. I'm trying move the Erase button out of my appHome.mxml and into my headerMenu.mxml but don't know how to execute the erase() on the Canvas instance. The first thing I thought to try was click=\"{appHome.myCanvas.erase()}\" but obviously that didn't work. \n\nI asked a similar question yesterday here: Flex executing a function on another view and I accepted the answer before I tried it. The problem is that the headermenu.mxml is not a child of appHome.mxml. They are both children of the main app.mxml. Secondly, the object that has the erase() is in a separate .as class I instantiate in appHome.mxml.\n\nI hope I described my question well enough. Thanks n advance to anyone that can help." ]

[ "Implement SQL Server 2016 Snapshot Isolation in C#/ADO.NET for SELECT queries", "In order to prevent long read operations from blocking short, frequent write operations in my existing mixed OLTP/reporting web application backed by SQL Server 2016, I want to use Snapshot Isolation on a few long-running queries. The queries have already been well indexed and just take a long time to run due to large amounts of data, and while I may use RCSI later, I would like to start by using the less invasive Snapshot Isolation.\n\nMy question is: how do I enable Snapshot Isolation on my SELECT queries in C#? It seems I would have to wrap my select queries in a transaction, which just feels totally wrong.\n\n List<Cat> cats = new List<Cat>();\n TransactionOptions transactionOption = new TransactionOptions\n {\n IsolationLevel = IsolationLevel.Snapshot\n };\n using (TransactionScope transactionScope = new TransactionScope(TransactionScopeOption.Required, transactionOption))\n {\n using (SqlConnection sqlConnection = new SqlConnection(databaseConnectionString))\n {\n using (SqlCommand sqlCommand = sqlConnection.CreateCommand())\n {\n sqlCommand.CommandText = \"proc_Select_A_Billion_Cats\";\n sqlCommand.CommandType = CommandType.StoredProcedure;\n\n sqlConnection.Open();\n\n using (SqlDataReader sqlDataReader = sqlCommand.ExecuteReader())\n {\n while (sqlDataReader.Read())\n {\n // SOME CODE HERE can read the Cat object in from data reader\n\n // Add this cat to the collection\n cats.Add(cat);\n }\n }\n }\n }\n }\n\n\n\nFrom http://www.levibotelho.com/development/plugging-isolation-leaks-in-sql-server/ I can see that in SQL Server 2014 and later the isolation level will be reset when the connection is returned to the pool, so that's good.\n\nBut can it be right to wrap a stored proc that does only SELECT in an ADO.NET transaction? Is there not some better way than this to implement Snapshot Isolation in C#?" ]

[ "How to override/replace GWT class in Maven project?", "I want to make some changes in AbstractCellTable class (change visibility of some fields and methods to protected or public etc). I've cloned AbstractCellTable.java file, made changes in it and put it into my Eclipse project 'commons' (with same package name com.google.gwt...).\n\nSome other GWT projects use commons project. They are in the same Eclipse workspace and use source dependency from commons. I can compile them and use replaced AbstractCellTable class using standard GWT Eclipse plugin.\n\nThe problem appears when I want to change my projects to Maven ones. There is no problem with installation of commons project (mvn clean install). Changed source file of AbstractCellTable.java appears in generated jar file. But when I'm compiling dependant projects I get compile errors. I don't have stacktrace now, but the reason of this problem lies in using by GWT compiler original version of AbstractCellTable class. Errors show that commons.jar has compile errors (sic!) even if was installed properly earlier.\n\nI've already tried to change ordering of dependencies in pom.xml, but it doesn't work. I'm thinking about installing own version of gwt-user.jar in my repo, but it won't be easy, as GWT project don't rely on Maven.\n\nIs there any better solution to replace original GWT classes?" ]

[ "Titan 1.0.0 FIXED configuration \"set-vertex-id\" - can be overriden?", "I'm trying to override the graph.set-vertex-id configuration in Titan 1.0.0 \n\nBy loading the configuration from an xml file:\n\n cache.db-cache-time = 180000\n cache.db-cache-size = 0.25\n graph.set-vertex-id=true\n storage.batch-loading=true\n....\n\n\nI'm getting the error :\n\n Local setting graph.set-vertex-id=true (Type: FIXED) is overridden by globally managed value (false). Use the ManagementSystem interface instead of the local configuration to control this setting.\n\n\nI also tried \n\n BaseConfiguration configuration = new BaseConfiguration();\n configuration.setProperty(\"storage.hostname\", \"any_hostname\");\n configuration.setProperty(\"storage.backend\", \"thrift\");\n configuration.setProperty(\"graph.set-vertex-id\", Boolean.TRUE);\n\ntitanGraph = TitanFactory.open(configuration);\n\n\nBut by checking the config with TitanManagement \n\n titanGraph.openManagement().get(\"graph.set-vertex-id\");\n\n\nI can see that it's still 'false'.\n\nHas anyone tried to assign custom vertices ids in this version of Titan? Before the upgrade we used Titan 0.4.2 and it worked just fine.\n\nThe documentation (http://s3.thinkaurelius.com/docs/titan/1.0.0/configuration.html ) says that\n\nGLOBAL: These options are always read from the cluster configuration and cannot be overwritten on an instance basis.\nFIXED: Like GLOBAL, but the value cannot be changed once the Titan cluster is initialized.\nWhen the first Titan instance in a cluster is started, the global configuration options are initialized from the provided local configuration file. Subsequently changing global configuration options is done through Titan’s management API. \nTo access the management API, call g.getManagementSystem() on an open Titan instance handle g. For example, to change the default caching behavior on a Titan cluster:\n\n mgmt = graph.openManagement()\n mgmt.get('cache.db-cache')\n // Prints the current config setting\n mgmt.set('cache.db-cache', true)\n // Changes option\n mgmt.get('cache.db-cache')\n // Prints 'true'\n mgmt.commit()\n // Changes take effect\n\n\nFirstly, there is no getManagementSystem() on a graph in Titan 1.0.0. Secondly, overriding the \"graph.set-vertex-id\" config like that will throw another error, because at this point the graph is already initialised:\n\n Cannot change the fixed configuration option: root.graph.set-vertex-id\n\n\nThank you !" ]
