• UITableViewCellStyleDefault label width

  - by Rob Bonner

  Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

• Session management with OpenID, in ASP.NET

  - by Andreas Grech

  I am currently playing with DotNetOpenAuth to make an ASP.NET (C#) website use OpenID instead of the normal login-password routine for user and session handling. Up till now, I have added the DotNetOpenAuth.dll into my project and tried a test login page with the following: <rp:OpenIdLogin ID="OpenIdLogin1" runat="server" /> When I run the page, I enter a valid myopenid url and the website redirects to the myopenid page, where I enter my password, and upon success, it returns back to my default.aspx, due to the following in my web.config: <authentication mode="Forms"> <forms defaultUrl="/Default.aspx" loginUrl="~/Login.aspx"/> </authentication> Now that the user is "logged in", how can handle my session? At the moment, I don't know how I can, for example, check if the session is still alive or how to terminate the session. My basic question is, how can I manage the session once the user is authenticated with OpenID ?

• SQL "JOIN" vs. "INNER JOIN"?

  - by froadie

  I recently came across a query that implements a join using just the "JOIN" keyword. On researching I saw that when using a join in SQL without specifying INNER or OUTER, the default is an INNER JOIN. I've never come across this syntax before; all the SQL I've written/read/worked with specifies INNER or some sort of OUTER (LEFT, RIGHT, FULL...). Is there any reason not to rely on the default? Is the plain JOIN widely used? What are the coding standards regarding JOIN vs. INNER JOIN?

• Read SharedPreferences when you haven't set the name of the file.

  - by Pentium10

  When you createa a PreferenceScreen on Android, your application creates a default SharedPreferences file for the settings. I want to read this name, or get a reference without specifing the name. Currently I use: SharedPreferences prefs = ctx.getSharedPreferences("prefs", 0); SharedPreferences.Editor ed=prefs.edit(); But this returns another copy of the preference. When I checked the folder in /data/data/myapk/shared_prefs I see two files, one named prefs.xml and the other is my [package name]_preferences.xml (this was created by the PreferenceActivity); How do I get an instance of the shared preference with the usage of the default file name, so I should not mention a name for it?

• Does this mySQL Stored Procedure Work?

  - by Laxmidi

  Hi, I got the following stored procedure from http://dev.mysql.com/doc/refman/5.1/en/functions-that-test-spatial-relationships-between-geometries.html Does this work?

• OneToOne JPA / Hibernate eager loading cause N+1 select

  - by Alexandre Lavoie

  I created a method to have multilingual text on different objects without creating field for each languages or tables for each objects types. Now the only problem I've got is N+1 select queries when doing a simple loading. Tables schema : CREATE TABLE `testentities` ( `keyTestEntity` int(11) NOT NULL, `keyMultilingualText` int(11) NOT NULL, PRIMARY KEY (`keyTestEntity`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8; CREATE TABLE `common_multilingualtexts` ( `keyMultilingualText` int(11) NOT NULL auto_increment, PRIMARY KEY (`keyMultilingualText`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8; CREATE TABLE `common_multilingualtexts_values` ( `languageCode` varchar(5) NOT NULL, `keyMultilingualText` int(11) NOT NULL, `value` text, PRIMARY KEY (`languageCode`,`keyMultilingualText`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; MultilingualText.java @Entity @Table(name = "common_multilingualtexts") public class MultilingualText implements Serializable { private Integer m_iKeyMultilingualText; private Map<String, String> m_lValues = new HashMap<String, String>(); public void setKeyMultilingualText(Integer p_iKeyMultilingualText) { m_iKeyMultilingualText = p_iKeyMultilingualText; } @Id @GeneratedValue @Column(name = "keyMultilingualText") public Integer getKeyMultilingualText() { return m_iKeyMultilingualText; } public void setValues(Map<String, String> p_lValues) { m_lValues = p_lValues; } @ElementCollection(fetch = FetchType.EAGER) @CollectionTable(name = "common_multilingualtexts_values", joinColumns = @JoinColumn(name = "keyMultilingualText")) @MapKeyColumn(name = "languageCode") @Column(name = "value") public Map<String, String> getValues() { return m_lValues; } public void put(String p_sLanguageCode, String p_sValue) { m_lValues.put(p_sLanguageCode,p_sValue); } public String get(String p_sLanguageCode) { if(m_lValues.containsKey(p_sLanguageCode)) { return m_lValues.get(p_sLanguageCode); } return null; } } And it is used like this on a object (having a foreign key to the multilingual text) : @Entity @Table(name = "testentities") public class TestEntity implements Serializable { private Integer m_iKeyEntity; private MultilingualText m_oText; public void setKeyEntity(Integer p_iKeyEntity) { m_iKeyEntity = p_iKeyEntity; } @Id @GeneratedValue @Column(name = "keyEntity") public Integer getKeyEntity() { return m_iKeyEntity; } public void setText(MultilingualText p_oText) { m_oText = p_oText; } @OneToOne(cascade = CascadeType.ALL) @JoinColumn(name = "keyText") public MultilingualText getText() { return m_oText; } } Now, when doing a simple HQL query : from TestEntity, I get a query selecting TestEntity's and one query for each MultilingualText that need to be loaded on each TestEntity. I've searched a lot and found absolutely no solutions. I have tested : @Fetch(FetchType.JOIN) optional = false @ManyToOne instead of @OneToOne Now I am out of idea!

• Invoking browser on streaming media URLs

  - by Maven

  I have a dirt simple little function that launches the blackberry browser on a streaming media file in order to launch the built in media player. Everything works fine but there is this annoying dialog every time from the browser asking me if I want to save or open the file. My answer is always "open" the file so is there a way I can make it default and not bring up the dialog each time? The code I'm using to launch the browser // Get the default sessionBrowserSession browserSession = Browser.getDefaultSession(); // now launch the URL browserSession.displayPage(url); This is on blackberry OS 5.0 Thanks!

• Can not set Character Encoding using sun-web.xml

  - by stck777

  I am trying to send special characters like spanish chars from my page to a JSP page as a form parameter. When I try get the parameter which I sent, it shows that as "?" (Question mark). After searching on java.net thread I came to know that I should have following entry in my sun-web.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Sun ONE Application Server 8.0 Servlet 2.4//EN" "http://www.sun.com/software/sunone/appserver/dtds/sun-web-app_2_4-0.dtd"> <sun-web-app> <locale-charset-info default-locale="es"> <locale-charset-map locale="es" charset="UTF-8"/> <parameter-encoding default-charset="UTF-8"/> </locale-charset-info> </sun-web-app> But it did not work with this approach still the character goes as "?".

• BizTalk and SQL: Alternatives to the SQL receive adapter. Using Msmq to receive SQL data

  - by Leonid Ganeline

  If we have to get data from the SQL database, the standard way is to use a receive port with SQL adapter. SQL receive adapter is a solicit-response adapter. It periodically polls the SQL database with queries. That’s only way it can work. Sometimes it is undesirable. With new WCF-SQL adapter we can use the lightweight approach but still with the same principle, the WCF-SQL adapter periodically solicits the database with queries to check for the new records. Imagine the situation when the new records can appear in very broad time limits, some - in a second interval, others - in the several minutes interval. Our requirement is to process the new records ASAP. That means the polling interval should be near the shortest interval between the new records, a second interval. As a result the most of the poll queries would return nothing and would load the database without good reason. If the database is working under heavy payload, it is very undesirable. Do we have other choices? Sure. We can change the polling to the “eventing”. The good news is the SQL server could issue the event in case of new records with triggers. Got a new record –the trigger event is fired. No new records – no the trigger events – no excessive load to the database. The bad news is the SQL Server doesn’t have intrinsic methods to send the event data outside. For example, we would rather use the adapters that do listen for the data and do not solicit. There are several such adapters-listeners as File, Ftp, SOAP, WCF, and Msmq. But the SQL Server doesn’t have methods to create and save files, to consume the Web-services, to create and send messages in the queue, does it? Can we use the File, FTP, Msmq, WCF adapters to get data from SQL code? Yes, we can. The SQL Server 2005 and 2008 have the possibility to use .NET code inside SQL code. See the SQL Integration. How it works for the Msmq, for example: ·         New record is created, trigger is fired ·         Trigger calls the CLR stored procedure and passes the message parameters to it ·         The CLR stored procedure creates message and sends it to the outgoing queue in the SQL Server computer. ·         Msmq service transfers message to the queue in the BizTalk Server computer. ·         WCF-NetMsmq adapter receives the message from this queue. For the File adapter the idea is the same, the CLR stored procedure creates and stores the file with message, and then the File adapter picks up this file. Using WCF-NetMsmq adapter to get data from SQL I am describing the full set of the deployment and development steps for the case with the WCF-NetMsmq adapter. Development: 1.       Create the .NET code: project, class and method to create and send the message to the MSMQ queue. 2.       Create the SQL code in triggers to call the .NET code. Installation and Deployment: 1.       SQL Server: a.       Register the CLR assembly with .NET (CLR) code b.      Install the MSMQ Services 2.       BizTalk Server: a.       Install the MSMQ Services b.      Create the MSMQ queue c.       Create the WCF-NetMsmq receive port. The detailed description is below. Code .NET code … using System.Xml; using System.Xml.Linq; using System.Xml.Serialization;   //namespace MyCompany.MySolution.MyProject – doesn’t work. The assembly name is MyCompany.MySolution.MyProject // I gave up with the compound namespace. Seems the CLR Integration cannot work with it L.

Creating the WCF-NetMsmq receive port I will not go through this step in all details. It is straightforward. URI for this receive location should be 'net.msmq://localhost/private/myapp.myqueue'. Notes ·         The biggest problem is usually on the step the “Registering the CLR assembly”. It is hard to predict where are the assemblies from the assembly list, what version should be used, x86 or x64. It is pity of such “rude” integration of the SQL with .NET. ·         In couple cases the new WCF-NetMsmq port was not able to work with the queue. Try to replace the WCF- NetMsmq port with the WCF-Custom port with netMsmqBinding. It was working fine for me. ·         To test how messages go through the queue you can turn on the Journal /Enabled option for the queue. I used the QueueExplorer utility to look to the messages in Journal. The Computer Management can also show the messages but it shows only small part of the message body and in the weird format. The QueueExplorer can do the better job; it shows the whole body and Xml messages are in good color format.

  I am using the Expression Encoder SDK to encode .avi and Flash files to a .wmv format suitable for Silverlight. By default, EE encodes files with audio using the the WMA PRO codec. If you are running Windows Server 2003, this is a problem as it doesn't support the WMA PRO codec and produces and error message similar to the following. Error Message: The Audio Profile settings do not match a valid system profile. Error Source: Microsoft.Expression.Encoder Error Target Site: System.String GetProfileString() I am looking for a way to change the default audio codec to something suitable for WS 2003. I am aware that although not supported natively, there is a highly invasive way to install Windows Media Player 11 and it's codecs on WS 2003 but this involves registry tinkering and other hacks not suitable for our production environments so that solution is out.

I want it in the same format i.e 'li' after droping it. $(function() { $( "#catalog ul" ).sortable({ zIndex: 10000, revert: true }); $( "#catalog" ).accordion(); $( "#catalog ul" ).draggable({ appendTo: "body", helper: "clone", zIndex: 10000 }); $( "#dialogIteration ol" ).droppable({ activeClass: "ui-state-default", hoverClass: "ui-state-hover", drop: function( event, ui ) { $( this ).find( ".placeholder" ).remove(); $( "<li></li>" ).text( ui.draggable.text() ).appendTo( this ); } }).sortable({ items: "li:not(.placeholder)", sort: function() { // gets added unintentionally by droppable interacting with sortable // using connectWithSortable fixes this, but doesn't allow you to customize active/hoverClass options $( this ).removeClass( "ui-state-default" ); } }); $( "ul, li" ).disableSelection(); $("#dialogIteration").dialog(); }); Demo: http://jsfiddle.net/coolanuj/7683X/7/

• FxCop giving a warning on private constructor CA1823 and CA1053

  - by Luis Sánchez

  I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

• User Mode Linux - Installing a module error

  - by Zach

  I am trying to run 'make' on a module in User Mode Linux to install a simple makefile. Here is my make file: obj-m := hello.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules When I run this in User Mode Linux I get the following error: make[1]: Entering directory /lib/modules/2.6.28/build' make[1]: *** No rule to make targetmodules'. Stop. make[1]: Leaving directory `/lib/modules/2.6.28/build' make: * [default] Error 2 The problem is that no files are present under /lib/modules/. There's no directory for 2.6.28 or build. From what I've read, these should be symlinks to /usr/src, but under /usr/src, I don't see any files under that either.

• AccessControlException: access denied - caller function failed to load properties file

  - by Michael Mao

  Hi all: I am having a jar archive environment which is gonna call my class in a folder like this: java -jar "emarket.jar" ../tournament 100 My compiled class is deployed into the ../tournament folder, this command runs well. After I changed my code to load a properties file, it gets the following exception message: Exception in thread "main" java.security.AccessControlException: access denied (java.io.FilePermission agent.properties read) 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.checkRead(Unknown Source) at java.io.FileInputStream.<init>(Unknown Source) at java.io.FileInputStream.<init>(Unknown Source) at Agent10479475.getPropertiesFromConfigFile(Agent10479475.java:110) at Agent10479475.<init>(Agent10479475.java:100) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at java.lang.Class.newInstance0(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at emarket.client.EmarketSandbox.instantiateClientObjects(EmarketSandbox.java:92) at emarket.client.EmarketSandbox.<init>(EmarketSandbox.java:27) at emarket.client.EmarketSandbox.main(EmarketSandbox.java:166) I am wondering why this security checking will fail. I issue the getPropertitiesFromConfigFile() function inside my class's default constructor, like this: public class Agent10479475 extends AbstractClientAgent { //default constructor public Agent10479475() { //set all properties to their default values in constructor FT_THRESHOLD = 400; FT_THRESHOLD_MARGIN = 50; printOut("Now loading properties from a config file...", ""); getPropertiesFromConfigFile(); printOut("Finished loading",""); } private void getPropertiesFromConfigFile() { Properties props = new Properties(); try { props.load(new FileInputStream("agent.properties")); FT_THRESHOLD = Long.parseLong(props.getProperty("FT_THRESHOLD")); FT_THRESHOLD_MARGIN = Long.parseLong(props.getProperty("FT_THRESHOLD_MARGIN ")); } catch(java.io.FileNotFoundException fnfex) { printOut("CANNOT FIND PROPERTIES FILE :", fnfex); } catch(java.io.IOException ioex) { printOut("IOEXCEPTION OCCURED :", ioex); } } } My class is loading its own .properties file under the same folder. why would the Java environment complains about such a denial of access? Must I config the emarket.client.EmarketSandbox class, which is not written by me and stored inside the emarket.jar, to access my agent.properties file? Any hints or suggestions is much appreciated. Many thanks in advance.

• Mono and Apache are serving files with no ASP.NET processing

  - by dnord

  On a new Rackspace Cloud Server box (Ubuntu 9.10), I've installed apache2, libapache2-mod-mono, and mod-mono-server2. I've disabled mod_mono and enabled mod_mono_auto, but whatever I do, requests for Default.aspx return the actual contents of Default.aspx (in this case, "This is a marker file generated by the precompilation tool, and should not be deleted!") I've installed XSP, and it looks like it works okay, but I'd like to use Apache with mod_mono (seems a more common configuration) if I can get it running. However, this is no error messages and no hints, with Google obviously not terribly helpful. What else can I look for to make sure I'm configured correctly? How can I test further?

• Unable to set relative path for flash file in ASP.NET MVC using AC_FL_RunContent

  - by Mahesh

  Hi, I have a website using asp.net mvc in which I need to embed a flash file in view. I am unable to set the relative path for the flash file. Given below is the code I am using: AC_FL_RunContent( 'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0', 'width', '487', 'height', '359', 'menu', 'false', 'movie', 'images/butterfly', 'quality', 'high', 'allowscriptaccess', 'sameDomain', 'pluginspage', 'http://www.macromedia.com/go/getflashplayer' ); where I copied butterfly.swf in a directory called images. images directory resides in the views folder. If I use code behind( default.aspx default.aspx.cs) in a different solution with the same folder strucuture, browser is able to load the flash file. Could you please throw some light on the MVC folder structure issue?? Thanks a lot. Mahesh

• How do I set my development web browser in VS2010?

  - by blesh

  I don't like to use IE for my system default web browser. but I do want to set IE as my browser in VS2010 because it works a little nicer for debugging and I like to develop to the lowest common denominator. (jab, lol)... anyhow, can I default to debugging against IE? I know in VS2008 you just had to "Browse With..." on an .aspx page. But that option doesn't exist in VS2010 RC. What gives?
