• Problem with XElement and XslCompiledTransform

  - by Graham Clark

  I'm having some trouble using a combination of XElement and XslCompiledTransform. I've put the sample code I'm using below. If I get my input XML using the GetXmlDocumentXml() method, it works fine. If I use the GetXElementXml() method instead, I get an InvalidOperationException when calling the Transform method of XslComiledTransform: Token Text in state Start would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. The CreateNavigator method on both XElement and XmlDocument returns an XPathNavigator. What extra stuff is XmlDocument doing so this all works, and how can I do the same with XElement? Am I just doing something insane? static void Main(string[] args) { XslCompiledTransform stylesheet = GetStylesheet(); // not shown for brevity IXPathNavigable input = this.GetXElementXml(); using (MemoryStream ms = this.TransformXml(input, stylesheet)) { XmlReader xr = XmlReader.Create(ms); xr.MoveToContent(); } } private MemoryStream TransformXml( IXPathNavigable xml, XslCompiledTransform stylesheet) { MemoryStream transformed = new MemoryStream(); XmlWriter writer = XmlWriter.Create(transformed); stylesheet.Transform(xml, null, writer); transformed.Position = 0; return transformed; } private IXPathNavigable GetXElementXml() { var xml = new XElement("x", new XElement("y", "sds")); return xml.CreateNavigator(); } private IXPathNavigable GetXmlDocumentXml() { var xml = new XmlDocument(); xml.LoadXml("<x><y>sds</y></x>"); return xml.CreateNavigator(); }

• how to display a JFrame from an applet?

  - by mithun1538

  Hello everyone, I have this class called PollFrame that extends JFrame in a file called PollFrame.java . PollFrame contains a form. I have an applet, which has a button in it. When the button is clicked, I want the PollFrame to be displayed. I set the ActionPerformed as: Pollframe poll = new PollFrame(); // This initializes the form poll.setVisible(true); However, when I click the button, I get the following error : Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM.0) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkExit(Unknown Source) at javax.swing.JFrame.setDefaultCloseOperation(Unknown Source) at com.org.pollFrame.initComponents(pollFrame.java:54) at com.org.pollFrame.<init>(pollFrame.java:11) at com.org.EmployeeApplet.requestRoomActionPerformed(EmployeeApplet.java:216) at com.org.EmployeeApplet.access$300(EmployeeApplet.java:7) at com.org.EmployeeApplet$4.actionPerformed(EmployeeApplet.java:71) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) I am guessing fromt he above error that calling another class file from an applet is prohibited. Is there any way I can display the PollFrame from the applet?

• Getting a ResultSet/RefCursor over a database link

  - by JonathanJ

  From the answers to http://stackoverflow.com/questions/1122175/calling-a-stored-proc-over-a-dblink it seems that it is not possible to call a stored procedure and get the ResultSet/RefCursor back if you are making the SP call across a remote DB link. We are also using Oracle 10g. We can successfully get single value results across the link, and can successfully call the SP and get the results locally but we get the same 'ORA-24338: statement handle not executed' error when reading the ResultSet from the remote DB. My question - is there any workaround to using the stored procedure? Is a shared view a better solution? Piped rows? Sample Stored Procedure: CREATE OR REPLACE PACKAGE BODY example_SP IS PROCEDURE get_terminals(p_CD_community IN community.CD_community%TYPE, p_cursor OUT SYS_REFCURSOR) IS BEGIN OPEN p_cursor FOR SELECT cd_terminal FROM terminal t, community c WHERE c.cd_community = p_CD_community AND t.id_community = c.id_community; END; END example_SP; / Sample Java code that works locally but not remotely: Connection conn = DBConnectionManagerFactory.getDBConnectionManager().getConnection(); CallableStatement cstmt = null; ResultSet rs = null; String community = "EXAMPLE"; try { cstmt = conn.prepareCall("{call example_SP.get_terminals@remote_address(?,?)}"); cstmt.setString(1, community); cstmt.registerOutParameter(2, OracleTypes.CURSOR); cstmt.execute(); rs = (ResultSet)cstmt.getObject(2); while (rs.next()) { LogUtil.getLog().logInfo("Terminal code=" + rs.getString( "cd_terminal" )); } }

• Will IOC solve our problems?

  - by user127954

  Just trying to implement unit testing into a brownfield type system. Be aware i'm relatively new into the unit testing world. Its going to be a gradual migration of course because there are just so many areas of pain. The current problem i'm trying to solve is we followed a lot of bad practices from our VB6 days and in the conversion of our app to .Net. We have LOT AN LOTS of shared/static functions which call other shared functions and those call others and so on. Sometimes depedencies are passed in as parameters and sometimes they are just newed up within the calling function. I've already instructed our developers to stop creating shared functions and instead create instance members and only use those instance members off of interfaces but that doesn't alleviate the current situation. So you must recursively pass in each and every dependency at the top layer for each function in your code path and method signatures are turning into a mess. I'm hoping this is something that IOC will fix. Currently we are using NUnit/Moq and i'm starting to investigate StructureMap. So far i understand that you pretty much tell StructureMap for x interface i want to default to the concrete class y: ObjectFactory.Initialize(x=>{x.ForRequestType<IInterface>().TheDefaultIsConcreteType<MyClass>()}); Then to runtime: var mytype = ObjectFactory.GetInstance<IInterface>(); the IOC container will initialize the correct type for you. Not sure yet how to swap a fake in for the concrete type but hopefully thats simple. Again will IOC solve the problems i was talking about above? Is there a specific IOC framework that will do it better than StructureMap or can they all handle this situation. Any help would be much appreciated.

• Fail to load NPAPI plugin in Google Chrome on Mac OS X

  - by Roman

  I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

• how to escape white space in bash loop list

  - by MCS

  I have a bash shell script that loops through all child directories (but not files) of a certain directory. The problem is that some of the directory names contain spaces. Here are the contents of my test directory: $ls -F test Baltimore/ Cherry Hill/ Edison/ New York City/ Philadelphia/ cities.txt And the code that loops through the directories: for f in `find test/* -type d`; do echo $f done Here's the output: test/Baltimore test/Cherry Hill test/Edison test/New York City test/Philadelphia Cherry Hill and New York City are treated as 2 or 3 separate entries. I tried quoting the filenames, like so: for f in `find test/* -type d | sed -e 's/^/\"/' | sed -e 's/$/\"/'`; do echo $f done but to no avail. There's got to be a simple way to do this. Any ideas? The answers below are great. But to make this more complicated - I don't always want to use the directories listed in my test directory. Sometimes I want to pass in the directory names as command-line parameters instead. I took Charles' suggestion of setting the IFS and came up with the following: dirlist="${@}" ( [[ -z "$dirlist" ]] && dirlist=`find test -mindepth 1 -type d` && IFS=$'\n' for d in $dirlist; do echo $d done ) and this works just fine unless there are spaces in the command line arguments (even if those arguments are quoted). For example, calling the script like this: test.sh "Cherry Hill" "New York City" produces the following output: Cherry Hill New York City Again, I know there must be a way to do this - I just don't know what it is...

• How to check for server side update in iPhone application Web service request

  - by Nirmal

  Hello All.... I have kind of Listing application for iPhone application, which always calling a web service to my php server and fetching the data and displaying it onto iPhone screen. Now, the thing to consider in this scenario is, my iPhone application everytime requesting on the server and fetching the data. But now my requirement is like I want to replace following set of actions with above one : - Everytime when my application is launched in iPhone, it should check for the new data at the server`. - And if server replies "true" then only my iPhone application will made a request to fetch the data. - In case of "false", my iPhone application will display the data which is already cached in local phone memory. Now to implement this scenario at server side (which has php, mysql), I am planning with the following solution : Table : tblNewerData id newDataFlag == ============ 1 true Trigger : tgrUpdateNewData Above trigger will update the tblNewerData - newDataFlag field on Insert case of my main table. And every time my iPhone app will request for tblNewerData-newDataFlag field, and if it found true then only it will create new request, and if it founds false then the cached version of data will be displayed. So, I want to know that, is it the correct way to do so ? or else any other smart option available ? Thanks in advance.

• WPF Background Thread Invocation

  - by jeffn825

  Maybe I'm mis-remembering how Winforms works or I'm overcomplicating the hell out of this, but here's my problem. I have a WPF client app application that talks to a server over WCF. The current user may "log out" of the WPF client, which closes all open screens, leaves only the navigation pane, and minimizes the program window. When the user re-maximizes the program window, they are prompted to log in. Simple. But sometimes things happen on background threads - like every 5 minutes the client tries to make a WCF calls that refreshes some cached data. And what if the user is logged out when this 5 minute timer triggers? Well, then the user should be prompted to log back in...and this must of course happen on the UI thread. private static ISecurityContext securityContext; public static ISecurityContext SecurityContext { get { if (securityContext == null) { // Login method shows a window and prompts the user to log in Application.Current.Dispatcher.Invoke((Action)Login); } return securityContext; } } So far so good, right? But what happens when multiple threads hit this spot of code? Well, my first intuition was that since I'm syncrhonizing across the Application.Current.Dispatcher, I should be fine, and whichever thread hit first would be responsible for showing the login form and getting the user logged in... Not the case... Thread 1 will hit the code and call ShowDialog on the login form Thread 2 will also hit the code and will call Login as soon as Thread 1 has called ShowDialog, since calling ShowDialog unblocked Thread 1 (I believe because of the way the WPF message pump works) All I want is a synchronized way of getting the user logged back into the application...what am I missing here? Thanks in advance.

• SimpleJdbcCall ignoring JdbcTemplate fetch size

  - by user289429

  We are calling the pl/sql stored procedure through Spring SimpleJdbcCall, the fetchsize set on the JdbcTemplate is being ignored by SimpleJdbcCall. The rowmapper resultset fetch size is set to 10 even though we have set the jdbctemplate fetchsize to 200. Any idea why this happens and how to fix it? Have printed the fetchsize of resultset in the rowmapper in the below code snippet - Once it is 200 and other time it is 10 even though I use the same JdbcTemplate on both occassion. This direct execution through jdbctemplate returns fetchsize of 200 in the row mapper jdbcTemplate = new JdbcTemplate(ds); jdbcTemplate.setResultsMapCaseInsensitive(true); jdbcTemplate.setFetchSize(200); List temp = jdbcTemplate.query("select 1 from dual", new ParameterizedRowMapper() { public Object mapRow(ResultSet resultSet, int i) throws SQLException { System.out.println("Direct template : " + resultSet.getFetchSize()); return new String(resultSet.getString(1)); } }); This execution through SimpleJdbcCall is always returning fetchsize of 10 in the rowmapper jdbcCall = new SimpleJdbcCall(jdbcTemplate).withSchemaName(schemaName) .withCatalogName(catalogName).withProcedureName(functionName); jdbcCall.returningResultSet((String) outItValues.next(), new ParameterizedRowMapper<Map<String, Object>>() { public Map<String, Object> mapRow(ResultSet rs, int row) throws SQLException { System.out.println("Through simplejdbccall " + rs.getFetchSize()); return extractRS(rs, row); } }); outputList = (List<Map<String, Object>>) jdbcCall.executeObject(List.class, inParam);

• Strange UIKit bug, table view row stays selected

  - by Can Berk Güder

  I'm facing what appears to be a UIKit bug, and it takes the combination of two less commonly used features to reproduce it, so please bear with me here. I have quite the common view hierarchy: UITabBarController -> UINavigationController -> UITableViewController and the table view controller pushes another table view controller onto the navigation controller's stack when a row is selected. There's absolutely nothing special or fancy in the code here. However, the second UITableViewController, the "detail view controller" if you will, does two things: It sets hidesBottomBarWhenPushed to YES in its init method, so the tab bar is hidden when this controller is pushed: - (id)initWithStyle:(UITableViewStyle)style { if(self = [super initWithStyle:style]) { self.hidesBottomBarWhenPushed = YES; } return self; } It calls setToolbarHidden:NO animated:YES and setToolbarHidden:YES animated:YES on self.navigationController in viewWillAppear: and viewWillDisappear: respectively, causing the UIToolbar provided by UINavigationController to be displayed and hidden with animations: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setToolbarHidden:NO animated:YES]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.navigationController setToolbarHidden:YES animated:YES]; } Now, if the second UITableViewController was pushed by selecting the row at the bottom of the screen (it doesn't have to be the last row) in the first controller, this row does not automatically get deselected when the user immediately or eventually returns to the first controller. Further, the row cannot be deselected by calling deselectRowAtIndexPath:animated: on self.tableView in viewWillAppear: or viewDidAppear: in the first controller. I'm guessing this is a bug in UITableViewController's drawing code which of course only draws visible rows, but unfortunately fails to determine correctly if the bottommost row will be visible in this case. I failed to find anything on this on Google or OpenRadar, and was wondering if anyone else on SO had this problem or knew a solution/workaround.

• How to resize a Flot graph when its containing div changes size

  - by Will Gorman

  I'm using the Flot graphing library jQuery plugin and I haven't found a good way to handle resizing the graph when it's containing <div> changes size (for example, due to window resizing). When handling the onresize event, I've made sure that the width and height of the containing <div>are updated to the correct size and then tried calling both setupGrid and draw on the plot object but with no effect. I've had some success with the approach of just removing and readding the containing <div> and replotting the graph in it. However, this seems to be prone to getting stuck in infinite resize event loops if I have to add other <div> elements to the document at the same time (like for tooltips for the graph) as I'm guessing those can trigger resize events as well? Is there a good way to handle it that I'm missing? (I'm also using ExplorerCanvas for IE in order to be able to use Flot, if that might have anything to do with it. I haven't really tried in any other browsers yet)

• Silverlight performance with a large number of Objects Org Chart.

  - by KC

  Hello, I’m working on a org chart project(SL 3) and I’m seeing the UI thread hang when the chart is building around 2,000 nodes and when it renders it takes about a min and then FPS drop to a crawl. Here is the code flow. Page.xaml.cs calls a wcf service that returns a list of AD users. Then we use Linq to build a collection of nodes to bind to the Orgchart.cs OrgChart.cs is a canvas and displays a collection of nodes and connecting lines. Node.cs is a canvas and has user data can contain children nodes. NodeContent.xaml is a user control that has borders so I can set the background, textblocks to display user's data, Events that handle the selected and expaned nodes, and storyboards that resize the nodes when they are selected or expanded.I noticed during hours of debugging , here in the InitializeComponent(); section where it loads the xaml it seems to be where the preformance hit is happening. System.Windows.Application.LoadComponent(this, new System.Uri("/Silverlight.Custom;component/NodeContent.xaml", System.UriKind.Relative)); So I guess I have two questions. Can threading help in any way with the UI thread hanging while drawing the nodes? How can I avoid the hit when calling this user control? Any advice or direction anyone can lend would be greatly appreciated. Thanks, KC

• DataContract Known Types - passing array

  - by Erup

  Im having problems when passing an generic List, trough a WCF operation. In this case, there is a List of int. The example 4 is described here in MSDN. Note that in MSDN sample, is described: // This will serialize and deserialize successfully because the generic List is equivalent to int[], which was added to known types. Above, is the DataContract: [DataContract] [KnownType(typeof(int[]))] [KnownType(typeof(object[]))] public class AccountData { [DataMember] public object accNumber1; [DataMember] public object accNumber2; [DataMember] public object accNumber3; [DataMember] public object accNumber4; } In client side, Im calling the operation like this: DataTransfer.Service.AccountData data = new DataTransfer.Service.AccountData() { accNumber1 = 100, accNumber2 = new int[100], accNumber3 = new List<int>(), accNumber4 = new ArrayList() }; cService.AddAccounts(data); Also, here is the decorations of the generated AccountData obj (WCF proxy): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AccountData", Namespace="http://schemas.datacontract.org/2004/07/DataTransfer.Service")] [System.SerializableAttribute()] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.PurchaseOrder))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.Customer))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(int[]))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(object[]))]

• AutoMapper How To Map Object A To Object B Differently Depending On Context

  - by IanT8

  Calling all AutoMapper gurus! I'd like to be able to map object A to object B differently depending on context at runtime. In particular, I'd like to ignore certain properties in one mapping case, and have all properties mapped in another case. What I'm experiencing is that Mapper.CreateMap can be called successfully in the different mapping cases however, once CreateMap is called, the map for a particular pair of types is set and is not subsequently changed by succeeding CreateMap calls which might describe the mapping differently. I found a blog post which advocates Mapper.Reset() to get round the problem, however, the static nature of the Mapper class means that it is only a matter of time before a collision and crash occur. Is there a way to do this? What I think I need is to call Mapper.CreateMap once per appdomain, and later, be able to call Mapper.Map with hints about which properties should be included / excluded. Right now, I'm thinking about changing the source code by writing a non-static mapping class that holds the mapping config instance based. Poor performance, but thread safe. What are my options. What can be done? Automapper seems so promising.

• Web service SSL handshake fails in production environment unless SSL debugging enabled

  - by JST

  Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

  - by Amr Bekhit

  Hello all, I am developing an ASP.NET web application that incorporates google maps. I have an ASP.NET listbox on my page which contains a list of items. When the user selects one of the items, I'd like to show this item on the map. The main complication lies in the fact that google maps uses javascript to control it and the listbox is a server control. I can think of two ways to do this. The first would involve the listbox calling a javascript function when the user selects a new item. I can then write this function to perform the necessary map operations. Unfortunately, the OnSelectedIndexChanged property of the listbox doesn't seem to support javascript functions. The second involves wrapping an UpdatePanel around the listbox and getting the listbox to perform a postback. In the SelectedIndexChanged event in VB/C#, I would the need to somehow make a call to a javascript function which would then update the map. Which solution can I use? Thanks --Amr

• Facebook Connect application inside iframe not working in IE7

  - by Antoine Aubry

  I am building a Facebook Connect application that runs inside a Google gadget. Being a gadget means that the application runs inside an iframe. Inside the application, there is a form that allows registered users to post comments. The submission is made using AJAX, but I get the same results with a normal form. The problem is that I need to get the user's facebook id. In Firefox, it works fine, but on Internet Explorer 7, I get the following error: 'A session key is required for calling this method' I believe that this is due to the way IE handles third-party cookies, because if I go to Internet options / Privacy / Advanced, and check Override automatic cookie handling and accept all cookies, it works fine. I cannot pass the Facebook id from the javascript, because anyone could tamper it. EDIT: If I open the content of the iframe directly, the app works fine. The problem is really due to the IFRAME and IE security model. What am I doing something wrong? How can I work around this problem?

• Problem with ar_mailer

  - by Roberto

  Hi guys, I'm running a strange problem sending emails. Basicly I'm getting this exception: ArgumentError (wrong number of arguments (1 for 0)): /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `initialize' /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `new' /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/base.rb:642:in `create' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:92:in `perform_delivery_activerecord' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:91:in `each' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ar_mailer.rb:91:in `perform_delivery_activerecord' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:508:in `__send__' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:508:in `deliver!' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/base.rb:383:in `method_missing' /app/controllers/web_reservations_controller.rb:29:in `test_email' In my web_reservations_controller I have a simply method calling TestMailer.deliver_send_email And my TesMailer is something like: class TestMailer < ActionMailer::ARMailer def send_email @recipients = "[email protected]" @from = "[email protected]" @subject = "TEST MAIL SUBJECT" @body = "<br>TEST MAIL MESSAGE" @content_type = "text/html" end end Do you have any idea? Thanks! Roberto

• Assert.AreEqual to not fail when comparing an enum and an int

  - by codingbear

  I'm not sure if this is doable, but I will just give a shot. I am calling Assert.AreEqual() method. For the parameters, I'm passing... an enum value which has Int32 as the underlying type because I didn't specify the base type an int (Int32) value Assert fails because it sees that the enum is not int (which is definitely correct). However, is there a way to make this Assert pass when the enum has the correct int value as the 2nd parameter? I can cast the enum to int and have it a quick fix, but it's really ugly. I was expecting some kind of overriding a method that Assert uses to compare 2 different objects and implicitly make that enum type look like an int. However, I wasn't successful at finding any hint/answer around that so far. Someone suggested to create a type converter and use the TypeConverterAttribute to get around. If this works for sure and is the only way to do it, I would; however, it does seem a lot of unnecessary work.

• Visual Studio project using the Quality Center API remains in memory

  - by Traveling Tech Guy

  Hi, Currently developing a connector DLL to HP's Quality Center. I'm using their (insert expelative) COM API to connect to the server. An Interop wrapper gets created automatically by VStudio. My solution has 2 projects: the DLL and a tester application - essentially a form with buttons that call functions in the DLL. Everything works well - I can create defects, update them and delete them. When I close the main form, the application stops nicely. But when I call a function that returns a list of all available projects (to fill a combo box), if I close the main form, VStudio still shows the solution as running and I have to stop it. I've managed to pinpoint a single function in my code that when I call, the solution remains "hung" and if I don't, it closes well. It's a call to a property in the TDC object get_VisibleProjects that returns a List (not the .Net one, but a type in the COM library) - I just iterate over it and return a proper list (that I later use to fill the combo box): public List<string> GetAvailableProjects() { List<string> projects = new List<string>(); foreach (string project in this.tdc.get_VisibleProjects(qcDomain)) { projects.Add(project); } return projects; } My assumption is that something gets retained in memory. If I run the EXE outside of VStudio it closes - but who knows what gets left behind in memory? My question is - how do I get rid of whatever calling this property returns? Shouldn't the GC handle this? Do I need to delve into pointers? Things I've tried: getting the list into a variable and setting it to null at the end of the function Adding a destructor to the class and nulling the tdc object Stepping through the tester function application all the way out, whne the form closes and the Main function ends - it closes, but VStudio still shows I'm running. Thanks for your assistance!

• OpenGL-ES: Change (multiply) color when using color arrays?

  - by arberg

  Following the ideas in OpenGL ES iPhone - drawing anti aliased lines, I am trying to draw stroked anti-aliased lines and I am successful so far. After line is draw by the finger, I wish to fade the path, that is I need to change the opacity (color) of the entire path. I have computed a large array of vertex positions, vertex colors, texture coordinates, and indices and then I give these to opengl but I would like reduce the opacity of all the drawn triangles without having to change each of the color coordinates. Normally I would use glColor4f(r,g,b,a) before calling drawElements, but it has no effect due to the color array. I am working on Android, but I believe it shouldn't make the big difference, as long as it is OpenGL-ES 1.1 (or 1.0). I have the following code : gl.glEnable(GL10.GL_BLEND); gl.glBlendFunc(GL10.GL_ONE, GL10.GL_ONE_MINUS_SRC_ALPHA); gl.glEnableClientState(GL10.GL_COLOR_ARRAY); gl.glShadeModel(GL10.GL_SMOOTH); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glEnable(GL10.GL_TEXTURE_2D); // Should set rgb to greyish, and alpha to half-transparent, the greyish is // just there to make the question more general its the alpha i'm interested in gl.glColor4f(.75f, .75f, .75f, 0.5f); gl.glVertexPointer(mVertexSize, GL10.GL_FLOAT, 0, mVertexBuffer); gl.glColorPointer(4, GL10.GL_FLOAT, 0, mColorBuffer); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTexCoordBuffer); gl.glDrawElements(GL10.GL_TRIANGLES, indexCount, GL10.GL_UNSIGNED_SHORT, mIndexBuffer.position(startIndex)); If I disable the color array gl.glEnableClientState(GL10.GL_COLOR_ARRAY);, then the glColor4f works, if I enable the color array it does nothing. Is there any way in OpenGl-ES to change the coloring without changing all the color coordinates? I think that in OpenGl one might use a fragment shader, but it seems OpenGL does not have a fragment shader (not that I know how to use one).
