• Programmatically enable tracing?

  - by fretje

  Is there a way to programmatically enable diagnostic tracing for a WSE web service client? This is how it should be configured using an app.config file: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="microsoft.web.services3" type="Microsoft.Web.Services3.Configuration.WebServicesConfiguration, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </configSections> <microsoft.web.services3> <diagnostics> <trace enabled="true" input="InputTrace.webinfo" output="OutputTrace.webinfo" /> </diagnostics> </microsoft.web.services3> </configuration> I would like to do this from code. Is this possible?

• In Mac OS X, what's the role of /usr/lib/dyld?

  - by diciu

  How is a binary executed? I'm guessing /usr/lib/dyld loads shared libraries into the binary's memory space and then jumps to whatever the program counter points to under LC_UNIXTHREAD. But who and how executes dyld?

  Consider the following XML: <?xml version="1.0" encoding="ISO-8859-1"?> <catalog> <cd> <title>Empire Burlesque</title> <artist> <name>Bob</name> <surname>Dylan</surname> </artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> </cd> </catalog> I want to add elements to this XML using XSLT, to get the following result: <?xml version="1.0" encoding="ISO-8859-1"?> <catalog> <cd> <title>Empire Burlesque</title> <artist> <name>Bob</name> <surname>Dylan</surname> <!-- NEW --> <middlename>???</middlename> </artist> <country>USA</country> <company>Columbia</company> <price>10.90</price> <year>1985</year> <!-- NEW --> <comment>great one</comment> </cd> <!-- NEW --> <cd> <title>Hide your heart</title> <artist> <name>Bonnie</name> <surname>Tyler</surname> </artist> <country>UK</country> <company>CBS Records</company> <price>9.90</price> <year>1988</year> </cd> </catalog> To achieve that, I wrote the following XSLT: <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template name="injectXml"> <xsl:param name="whatToInject"/> <xsl:copy> <xsl:copy-of select="node() | @*"/> <xsl:copy-of select="$whatToInject"/> </xsl:copy> </xsl:template> <xsl:template match="//catalog"> <xsl:call-template name="injectXml"> <xsl:with-param name="whatToInject"> <cd> <title>Hide your heart</title> <artist> <name>Bonnie</name> <surname>Tyler</surname> </artist> <country>UK</country> <company>CBS Records</company> <price>9.90</price> <year>1988</year> </cd> </xsl:with-param> </xsl:call-template> </xsl:template> <xsl:template match="//cd[year=1985]"> <xsl:call-template name="injectXml"> <xsl:with-param name="whatToInject"> <comment>great one</comment> </xsl:with-param> </xsl:call-template> </xsl:template> <xsl:template match="//cd[year=1985]/artist"> <xsl:call-template name="injectXml"> <xsl:with-param name="whatToInject"> <middlename>???</middlename> </xsl:with-param> </xsl:call-template> </xsl:template> </xsl:stylesheet> Why it's not working?

• How can I set a highlighted image on a table view cell?

  - by nevan

  I've followed the code in Apple's AdvancedTableViewCells and built a table view with a background image for cells. Now I want to change it so that instead of the blue highlight colour, it shows a darker version of my image. What are the steps I need to follow to do this? I'm using a UITableViewCell subclass with a custom NIB. My background image is implemented as the cell.backgroundView. The steps I've take so far are: Change the selectionStyle of the cell to "None" Set the Highlight colour on my UILabel subviews to a light colour Create a darker version of my background as a separate image Override setSelected: animated: I'm wondering about the next steps.

• Komodo Double Indentation with Tab

  - by T. Stone

  In Komodo Edit, if I name the file *.django.html it gives me django syntax highlighting BUT it also indents with a tab character (8 spaces) instead of giving me the usual 4 space indent. How can I fix this? I've tried changing the value in Edit Preferences Editor Indentation Language Settings, but that seems to have no effect on it. The indentation works as normal (4 spaces) if I'm using any other extension (.py, .html, etc.). Ideas?

• Linux's thread local storage implementation

  - by anon

  __thread Foo foo; How is "foo" actually resolved? Does the compiler silently replace every instance of "foo" with a function call? Is "foo" stored somewhere relative to the bottom of the stack, and the compiler stores this as "hey, for each thread, have this space near the bottom of the stack, and foo is stored as 'offset x from bottom of stack'"?

• Robust C# Plugin System

  - by Pete Kirkham

  I am writing a tool which communicates with more than one version control system, either subversion or clearcase, and has various utilities which can be plugged into it. I though of using MEF to load the version control providers, and utiilities, both of which have interfaces definied for them. I've started to use MEF for this. But if loading any plugin fails (on half my clients machines, the ClearCase COM bindings won't be present, so loading will fail, on the other half SVN won't be installed, so the SVN plugin won't load) though, MEF throws an exception and no plugin works; I was hoping that the rest of the plugins would load. [ImportMany(AllowRecomposition = true)] public IEnumerable<IVersionControl> RegisteredProviders { get; private set; } Instead, if any providers fail to construct themselves, then RegisteredProviders is null. Is there a simple way of configuring MEF to achieve this (reporting exceptions but loading other instances), or do I have to change the interface to delay their intialisation failure until after MEF has instantiated the objects?

• nHibernate multiple classes pointing to same table?

  - by Amitabh

  Is it a good idea to create a lighter version of an Entity in some cases just for performance reason pointing to same table but with fewer columns mapped. E.g If I have a Contact Table which has 50 Columns and in few of the related entities I might be interested in FirstName and LastName property is it a good idea to create a lightweight version of Contact table. E.g. public class LightContact { public int Id {get; set;} public string FirstName {get; set;} public string LastName {get; set;} } Also is it possible to map multiple classes to same table?

• Eclipse/Java code completion not working

  - by Rob

  I've downloaded, unzipped and setup Eclipse 3.4.2 with some plugins (noteable, EPIC, Clearcase, QuantumDB, MisterQ). Now I find when I'm editing Java projects the code completion is not working. If I type String. and press ctrl-space a popup shows "No Default Proposals" and the status bar at the bottom shows "No completions available". Any ideas? Thanks....

• Starting ActiveMQ message listener in Tomcat?

  - by Nick Swarr

  I've created an ActiveMQ MessageListener and configured it using Spring. I'm hosting the listener in Tomcat. When I start up the web application (that features only the listener), should the listener automatically start? Or do I need additional configuration? Here's what I have. First, updated the web.xml to allow spring to configure itself on startup, <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/spring/applicationContext.xml</param-value> </context-param> </web-app> Then I created the applicationContext.xml to configure the ActiveMQ listener, <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.somepackage"/> <context:property-placeholder location="classpath:env.properties"/> <bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="documentListener" class="com.somepackage.SomeListener" /> <bean id="container" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="cachingConnectionFactory"/> <property name="messageListener" ref="documentListener"/> <property name="destinationName" value="STOCKS.MSFT" /> </bean> <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="jmsFactory" /> <property name="sessionCacheSize" value="1" /> </bean> </beans> And that's it. Based on what I've seen around the web, I can't tell if that's all I need? Maybe I need some other configuration in Tomcat to kick off the listener?

• What does this web.xml error mean?

  <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"> Referenced file contains errors (http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd). For more information, right click on the message in the Problems View and select "Show Details..." The errors below were detected when validating the file "web-app_2_5.xsd" via the file "web.xml". In most cases these errors can be detected by validating "web-app_2_5.xsd" directly. However it is possible that errors will only occur when web-app_2_5.xsd is validated in the context of web.xml.

• Is there an online user agent database?

  - by Gary Richardson

  How do you parse your user agent strings? I'm looking to get: Browser Browser Version OS OS Version from a user agent string. My app is written in perl and was previously using HTTP::BrowserDetect. It's a bit dated and is no longer maintained. I'm in no way tied to using perl for the actual lookup. I've come to the conclusion that automagic parsing is a lost cause. I was thinking of writing a crud type app to show me a list of unclassified UA's and manually keep them up to date. Does such an resource already exist that I can tap into? It would be awesome if I could make an HTTP call to look up the user agent info. Thanks!

• How can I link glibc statically with qt

  - by yan bellavance

  I have built a static version of qt and download a static version of glibc. Now I would like to link glibc statically to my qt application. I know about going into the .pro and adding the line LIBS += -L path/to/static_lib but I am wondering if these that is enough? Will it still link glibc statically even though the OS I am building on has the dynamic libraries also? The reason I am doing this is to deploy the application in a standalone manner. (After installing and updating Red Hat 5.3 glibc_2.9 was not found on the target computer)

• How to make python_select work for '$>python' command?

  - by Jim

  I installed a couple of pythons in different versions with macports, and the apple python 2.6 is also working. Now I need to run a program which requires MySQLdb package support in python, and this package was installed to the python I installed by macports. The program tells me that there is no MySQLdb installed, so I guess it is the apple python working for that program. I searched for some help and found python_select for switching between pythons. However after the command $>sudo python_select python25 told me that it selected the version "python25" for python, when I type $>python it is still apple python 2.6 that launches. The question is that how can I make python25(the one with MySQLdb) work for the program rather than apple python? Another important thing, the program is NOT a .py file and needs to be compiled before running. So do I need to re-install this program? My Mac OS version is Snow Leopard 10.6. Any answer is appreciated.

• ado.net managing connections

  - by madlan

  Hi, I'm populating a listview with a list of databases on a selected SQL instance, then retrieving a value from each database (It's internal product version, column doesn't always exist) I'm calling the below function to populate the second column of the listview: item.SubItems.Add(DBVersionCheck(serverName, database.Name)) Function DBVersionCheck(ByVal SelectedInstance As String, ByVal SelectedDatabase As String) Dim m_Connection As New SqlConnection("Server=" + SelectedInstance + ";User Id=sa;Password=password;Database=" + SelectedDatabase) Dim db_command As New SqlCommand("select Setting from SystemSettings where [Setting] = 'version'", m_Connection) Try m_Connection.Open() Return db_command.ExecuteScalar().trim m_Connection.Dispose() Catch ex As Exception 'MessageBox.Show(ex.Message) Return "NA" Finally m_Connection.Dispose() End Try End Function This works fine except it's creating a connection to each database and leaving it open. My understanding is the close()\dispose() releases only the connection from the pool in ado rather than the actual connection to sql. How would I close the actual connections after I've retrieved the value? Leaving these open will create hundreds of connections to databases that will probably not be used for that session.

• Xml comparison in Python

  - by Gregg Lind

  Building on another SO question, how can one check whether two well-formed XML snippets are semantically equal. All I need is "equal" or not, since I'm using this for unit tests. In the system I want, these would be equal (note the order of 'start' and 'end'): <?xml version='1.0' encoding='utf-8' standalone='yes'?> <Stats start="1275955200" end="1276041599"> </Stats> # Reodered start and end <?xml version='1.0' encoding='utf-8' standalone='yes'?> <Stats end="1276041599" start="1275955200" > </Stats> I have lmxl and other tools at my disposal, and a simple function that only allows reordering of attributes would work fine as well!

I want to ignore the date text and display the event over the intire cell, I don't want to hardcode the height of the event. Hope to get some pointers, I have looked everywhere in the javascript and css.

• CSS - how can I handle the size difference between serif and sans-serif fonts?

  - by orbit82

  I'm working on a WordPress that will allow the site administrator to switch between sans-serif and serif fonts. I'm trying to code the stylesheet in such a way that the font sizes are similar whether or not they choose Georgia vs Arial. The problem is that when I have it looking nice with a serif font, it looks WAY too big when in sans-serif. When I then adjust it to look nice in a sans-serif font, it looks WAY too small in serif. Is there an ideal font size and line-height that works well with both serif and sans-serif? Or do I need to make separate stylesheets (a serf version and a sans-serif version)? P.S. I've set a base font size on the body at 12px, and then set the rest of the font sizes as a percentage of the base. Of course, this base font size could be set in ems or in percent, because the percentages will still scale proportionally.

• Upgrading framework on a ASP.Net MVC Solution

  - by Shiraz Bhaiji

  We have an ASP.Net MVC 1.0 solution developed using Visual Studio 2008 and .net Framework 3.5SP1. We would now like to upgrade Visual Studio to 2010. If we just open the solution in VS 2010 and do not change the framework version, can we just continue to develop as before? If we open the solution in VS 2010 and change the framework version to 4.0, will we automatically start using ASP.Net MVC 2.0, or will it continue to use ASP.Net MVC 1.0? Is there anything we need to take into consideration when upgrading to ASP.Net MVC 2.0? Thanks Shiraz
