• IIS URL Rewriting for all Inbound URLs?

  - by Rob Burke

  Hopefully a simple question although one I have found impossible to answer myself using the Googles! I have a website on IIS with the URL http://www.contoso.com/ which points to C:\www\public\ There has been a forced directory restructure so now all of the data (Default.aspx, Product.aspx, etc.) that originally resided in C:\www\public\ now resides in C:\www\public\en\ie\ - however, the IIS website document root is still C:\www\public\ So, essentially, I have a lot of inbound links to http://www.contoso.com/Product.aspx?id=1 (etc.) which are now returning 404 errors - the correct link is now http://www.contoso.com/en/ie/Product.aspx?id=1 Please consider that I can make no changes to the directory structure or the IIS document root... so must solve this issue using URL rewriting. Is it possible to capture all requests to contoso.com/* and rewrite them to contoso.com/en/ie/* ??

• JPA 2.0 Implementations comparison : Hibernate 3.5 vs EclipseLink 2 vs OpenJPA 2

  - by peperg

  What's your choice? Do You have any suggestions and experience? I'm developing an application with Hibernate 3.5 and Spring 3.0 Pros: Good documentation Easy configuration and helpful logs Popularity - wide community Some extensions to JPA Some additional Tools - JBoss Tools for Eclipse, hbm2ddl, generating static metamodel etc... Cons: Bugs! (Sequences, collections etc...) Lots of reatures are doubled with "pure" Hibernate. There's a mess in legacy Hibernate and JPA annotations. I'm considering to switch to EclipseLink. What do You think ? Edit: I've tried EclipseLink and have very bad experiences. It seems like EclipseLink needs LoadTimeWeaver and likes to run on OSGi platform rather than simple Jetty or Tomcat environment. I just don't have time for all this configuration stuff.

• Using Add-on SDK to add toolbar buttons? Integrating XUL and Add-on SDK for Firefox Add-ons?

  - by Salami

  I have already coded most of a Firefox add-on using the Add-on SDK API. I am now discovering that Add-on SDK might not be powerful enough for my purposes. I need two things: A drop down button in the toolbar next to the location bar. To modify the add-ons manager in firefox It is truly disappointing, but I don't believe either of these is possible with the Add-on SDK. First of all, I understand there is a widget module in the Add-on SDK API. But this only allows me to add a simple icon or label to the awkward add-on bar. What if I need to add a nicer button like the one next to the location bar for Firebug or Greasemonkey? As for modifying the add-ons manager in firefox, I have tried Nickolay Ponomarev's XUL with the Add-on SDK without any success whatsoever. If anyone knows how to get this working and can point me in the right direction that would be extremely helpful (cfx init --template xul doesn't do anything the regular SDK does when I try it)

• Creating <li> with JavaScript in an XUL Application

  - by echox

  Hi! I try to create some li elements in my XUL Application. Theres only the text of the elements shown, but no list typical bullets and linebreaks. Example: text text text text text text text Heres the JS Code I use to create the list: var li = document.createElement('html:li'); var txt = document.createTextNode("only shown as simple text"); li.appendChild(txt); document.getElementById('someList').appendChild(li); HTML: <html:ul id="someList"> <html:li>this is shown in correct list style</html:li> </html:ul> I tried 'html:li' and also 'li' but nothing worked.

• jQuery Star Rating plugin - select in callback causes infinite loop

  - by Ian

  Using the jQuery Star Rating plugin everything works well until I select a star rating from the rating's callback handler. Simple example: $('.rating').rating({ ... callback: function(value){ $.ajax({ type: "POST", url: ... data: {rating: value}, success: function(data){ $('.rating').rating('select', 1); } }); } }); I'm guessing this infinite loop occurs because the callback is fired after a manual 'select' as well. Once a user submits their rating I'd like to 'select' the average rating across all users (this value is in data returned to the success handler). How can I do this without triggering an infinite loop?

• Linq to SQL DataContext Windsor IoC memory leak problem

  - by Mr. Flibble

  I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC. For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception. If I force garbage collection the memory is released OK. My datacontext class is very simple: public class DataContextAccessor : IDataContextAccessor { private readonly DataContext dataContext; public DataContextAccessor(string connectionString) { dataContext = new DataContext(connectionString); } public DataContext DataContext { get { return dataContext; } } } The Windsor IoC webconfig to instantiate this looks like so: <component id="DataContextAccessor" service="DomainModel.Repositories.IDataContextAccessor, DomainModel" type="DomainModel.Repositories.DataContextAccessor, DomainModel" lifestyle="PerWebRequest"> <parameters> <connectionString> ... </connectionString> </parameters> </component> Does anyone know what the problem is, and how to fix it?

• How to Grant IIS 7.5 access to a certificate in certificate store?

  - by thames

  In Windows 2003 it was simple to do and one could use the winhttpcertcfg.exe (download) to give "NETWORK SERVICE" account access to a certificate. I'm now using Windows Server 2008 R2 with IIS 7.5 and I am unable to find where and how to set permissions access permissions to a certificate in the certificate store. This Post showed how to do it in Vista and that winhttpcertcfg features were added into the certificates mmc however it doesn't seem to work with imported certificates or doesn't work anymore on Server 2008 R2. So does anyone have any idea on how give IIS 7.5 the correct permissions to read a certificate from the certificate store? And also what account from IIS 7.5 that needs the permission.

• boost::program_options bug or feature?

  - by Dmitriy

  Very simple example: #include <string> #include <boost/program_options.hpp> namespace po = boost::program_options; int main(int argc, char* argv[]) { po::options_description recipients("Recipient(s)"); recipients.add_options() ("csv", po::value<std::string>(), "" ) ("csv_name", po::value<unsigned>(), "" ) ; po::options_description cmdline_options; cmdline_options.add(recipients); po::variables_map vm; po::store(po::command_line_parser(argc, argv).options(cmdline_options).run(), vm); po::notify(vm); return 0; } And some tests: >Test --csv test in option 'csv_name': invalid option value >Test --csv_name test in option 'csv_name': invalid option value >Test --csv_name 0 >Test --csv text in option 'csv_name': invalid option value >Test --csv 0 >Test --csv_name 0 >Test --csv_name 0 --csv text multiple occurrences Looks like that boost::program_option threats parameter "csv" as "csv_name". Is it a feature or bug?

• Where is a good place for a code review?

  - by Carlos Nunez

  Hi, all! A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together. Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed). Thanks, everyone! -Carlos Nunez

• Printing entire array in C#

  - by DMan

  I have a simple 2D array: int[,] m = {{0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} }; How can I print this out onto a text file or something? I want to print the entire array onto a file, not just the contents. For example, I don't want a bunch of zeroes all in a row: I want to see the {{0,0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0,0} }; in it.

• wpf combobox padding

  - by Jose

  This is a simple question How do you remove the space between the content of a combobox and the border of it. E.g. If the selection of a combobox is "Selection 1" then the "S" is drawn at the very top left of the ComboBox control with no whitespace spacing between it and top left portion of the control. I did this <ComboBox Padding="0"/> Even this: <ComboBox.ItemContainerStyle> <Style TargetType="ComboBoxItem"> <Setter Property="Padding" Value="0"/> </Style> </ComboBox.ItemContainerStyle> The specified ComboBox above is within a ListView GridViewColumn. Maybe that's messing with something. This doesn't remove the padding. Any ideas?

• How do I execute a command on a successful build on TFS2010?

  - by Simon_Weaver

  I've got TFS2010 up and running and building a webdeploy deployment package. Into my directory: C:\TFS-BUILDS\Example Build\Example Build_20100414.44\_PublishedWebsites I get the following two directories: WebsiteName WebsiteName_Package All I want to do is run the following command on a successful build - to deploy the site: WebsiteName_Package\WebsiteName.deploy /Y How can I customize the build process template to actually run that package? Under TFS 2010 you have to use the process templates (no more TFSBuild.csproj stuff). I've tried duplicating the DefaultProcessTemplate.xaml file, but it basically kills my Visual Studio when I open it. How can I edit the .xaml by hand to run this simple command on a successful build

• Are SOLID principles really solid?

  - by Arseny

  The first pattern stands for this acronym is SRP. Here is a quote. the single responsibility principle states that every object should have a single responsibility, and that responsibility should be entirely encapsulated by the class. That's is simple and clear till we start to code ) Suppose we have a class with well defined SRP. To serialize this class instances we need to add special atrributes to that class. So now the class have other responsibility. Dosen't it violate SRP? Let's see other story. Interface implementation. Then we implement an interface we simply add other responsibility say dispose its resorces or compare its instances or whatever. So my question. Is it possible to keep SRP complete? How can we do it?

• Why won't the VisualVM Profiler profile my application?

  - by Luke

  I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

• Python 2 vs Python 3 and Tutorial

  - by MR-J

  Hey guys. I am 12 years old and I have had a small amount of experience with BASIC. I am thinking about learning Python, but I’m not sure if I should learn the 2.6 version or the 3.0 version. I don’t really care about the support for libraries or anything along those lines quite yet. I was wondering if it is easier to code in 3.0 than 2.6. And is it more fun and productive? I would also appreciate it if you could point me in the right direction for a simple yet complete tutorial that is easy to understand and possible teaches Object Oriented Programing. I don’t really care if it teaches OOP or not. One more thing; if I do learn python, is it possible to easily compile a python source code file into a 'stand-alone' .exe file for Windows? I really liked that functionality in BASIC. Thanks!!!!

• Override default behavior of SPACE key in .net WinForms ListView

  - by Axarydax

  Hello, I'd like to implement some custom behavior of Space key in a ListView. Basically I'd like to toggle selected status of the item under cursor - that should be fairly simple this.FocusedItem.Selected = !this.FocusedItem.Selected; but alas, it also does the default action, which is to select the focused item. This way I am unable to 'unselect' the focused item. I've looked for similar problems and they suggest using PreviewKeyDown event, in which I would process the key and disallow the ListView to do its default action. But the PreviewKeyDown event argument has no "handled" property, so I cannot 'eat' this key.

• File counter adds 2 instead of 1

  - by Derk

  I made a simple counter, but it increments by 2 instead of 1. $handle = fopen('progress.txt', 'r'); $pro = fgets($handle); print $pro; // incremented by 2, WTF? fclose($handle); $handle = fopen('progress.txt', 'w'); fwrite($handle, $pro); fclose($handle); Everytime I read the file it has been incremented by 2, instead of 1.

• Setting the background color of WPF TabControl inactive tabs

  - by David Veeneman

  Is there a simple way to set the background brush of all inactive tabs in a WPF TabControl? I want to emulate the look of VS 2010 on a TabControl--the background color of the control's inactive tabs should match the background color of the window in which the TabControl is sited, so that you see only the text of the tab, and not the tab itself. I know it will take a ControlTemplate to do it; I am trying to figure out what to put in the control template. Put another way, How do I specify that a particular brush should be applied to all inactive tabs? Thanks for your help.

• Referencing code in VB.NET

  - by akramnik

  I'm not at all familiar with VB.NET or ASP. I need to create a simple page which makes a call to a remote web service. I used the wsdl utility which comes with the DotNet SDK to generate a service proxy and write it to a VB file. Unfortunately I have no idea how to reference this code in either my ASPX file or the code behind VB file so I can create an instance of the proxy. Edit: I should have qualified this by noting that I'm not using visual studio. I just coded up a .aspx with a .vb behind it and dropped it into an IIS location. Is there a way to do what you're suggesting outside of VS?

• Strange exceptions using FindControl after implementing master pages

  - by inderio

  I have some simple repeater code given here: <asp:Repeater ID="ResultsRepeater" runat="server" DataSourceID="ResultsDS"> <HeaderTemplate> <table id="Results" class="data"> <tr id="Header" runat="server"> <th>Item</th> </tr> </table> </HeaderTemplate> </asp:Repeater> I used to be able to then access the repeater to get said header, as such: HtmlTableRow header = ResultsRepeater.Controls[0].Controls[0].FindControl("Header") as HtmlTableRow; After implementing master pages, I noticed my calls to header.InnerText and .InnerHtml throw exceptions, specifically: 'header.InnerHtml' threw an exception of type 'System.NotSupportedException' 'header.InnerText' threw an exception of type 'System.NotSupportedException' Can anyone share what's going on with me? I am of course assuming master pages caused this, since it's the only thing I've changed besides minor updates (that should not affect this in any way).

• Building big, immutable objects without constructors having long parameter lists

  - by Malax

  Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

• C# WinForms & SQL bindings

  - by vent

  I have a MSSQL database with many tables and relations. I want to bind it to my C# GUI application with text- and combo-boxes. Which one is the best way to do it: (1) Everything done manually by own classes and methods: Import data to dataset or to many datatables separately, then create dictionaries to comboboxes, manually retrieve data to textboxes and create a sql statement if update action will be invoked, or, (2) Done automatically by VS: Connect my controls with BindingSource and BindingNavigator if needed. I know how to deal with the first one, but if the second way would be better, my question is — how to achieve it? I haven't dealt with automatically created databindings and I don't know how to tell to DataBinding property (Key|Value|Text) about relations and current row's ID. And what is the method to cancel/update changes in all GUI elements? I need a simple solution for this scenario. It's a quick-and-dirty academical project, which must only "work" and be as fast implemented as it can. Thanks

• Explicit return from a Ruby method - implementation hiding, reuse and optimisations.

  - by Chris McCauley

  Hi, Rather than allowing a Ruby method to blindly return the last statement evaluated, is there any advantage to returning nil explicitly? In terms of implementation hiding and reuse, it seems dangerous to blindly allow the last expression evaluated to be returned - isn't there a danger that a user will rely on this only to get a nasty surprise when the implementation is modified? Surely returning nil would be better unless an explicit return value was given. Following on, is there an optimisation that Ruby can make when the return is a simple type rather than a reference to a more complex object? Chris

• Raphael js library: problems with animateAlong in IE7

  - by Andrei

  Hi there, I'm having trouble making a simple shape move along a path in IE7 (the only version of IE I tried, actually). The following code works fine in chrome and firefox, but not IE. I couldn't find an obvious reason, has anybody seen something similar? canvas.path(rPath.path).attr("stroke", "blue"); var circle = canvas.circle(rPath.startX, rPath.startY, 5); circle.animateAlong(rPath.path, 3000, true); My rPath variable has the path and the starting point coordinates. Microsoft script debugger points to this line as the one where the code breaks: os.left != (t = x - left + "px") && (os.left = t); (line 2131 inside the uncompressed raphael.js script file, inside Element[proto].setBox = function (params, cx, cy) {...}) Any ideas? Any experience (good or bad) with raphael's animateAlong in IE7? TIA, Andrei

• How to solve this error when using kXML for Midlet (java)
