jquery ui autocomplete problem

- by Roger

Hi, i've got a select box containing countries, and when one is selected, i want my autocomplete data for the city field to load via ajax. here's my code: // Sets up the autocompleter depending on the currently // selected country $(document).ready(function() { var cache = getCities(); $('#registration_city_id').autocomplete( { source: cache } ); cache = getCities(); // update the cache array when a different country is selected $("#registration_country_id").change(function() { cache = getCities(); }); }); /** * Gets the cities associated with the currently selected country */ function getCities() { var cityId = $("#registration_country_id :selected").attr('value'); return $.getJSON("/ajax/cities/" + cityId + ".html"); } This returns the following json: ["Aberdare","Aberdeen","Aberystwyth","Abingdon","Accrington","Airdrie","Aldershot","Alfreton","Alloa","Altrincham","Amersham","Andover","Antrim","Arbroath","Ardrossan","Arnold","Ashford","Ashington","Ashton-under-Lyne","Atherton","Aylesbury","Ayr",... ] But, it doesn't work. When i start typing in the city box, the style changes so the autocompleter is doing something, but it won't display this data. If i hard-code the above it works. Can anyone see what's wrong? Thanks

Use VersionControlExt.Explorer outside Visual Studio

- by Ian

Hi All, I'm developing a TFS tool to assist the developers in our company. This said tool needs to be able to "browse" the TFS server like in the Source Control Explorer. I believe that by using VersionControlExt.Explorer.SelectedItems, a UI will pop-up that will enable the user to browse the TFS server (please correct me if I'm wrong). However, VersionControlExt is only accessible when developing inside Visual Studio (aka Plugin). Unfortunately, I am developing a Windows Application that won;t run inside VS. So the question is, Can I use VersionControlExt outside of Visual Studio? If yes, how? Here's an attempt on using the Changset Details Dialog outside of Visual Studio string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); Assembly vcControls = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Controls.dll"); Assembly vcClient = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Client.dll"); Type dialogChangesetDetailsType = vcControls.GetType("Microsoft.TeamFoundation.VersionControl.Controls.DialogChangesetDetails",true); Type[] ctorTypes = new Type[3] {vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.VersionControlSever"), vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.Changeset"), typeof(System.Boolean)}; ConstructorInfo ctorInfo = dialogChangesetDetailsType.GetConstructor(ctorTypes); Object[] ctorObjects = new Object[3] {VersionControlHelper.CurrentVersionControlServer, uc.ChangeSet, true}; Object oDialog = ctorInfo.Invoke(ctorObjects); dialogChangesetDetailsType.InvokeMember("ShowDialog", BindingFlags.InvokeMethod, null, oDialog, null);

Nginx virtual server only partially working with Java application

- by MFB

Final Cut Server is a Java application (made by Apple) which launches from a web page. I have Nginx in front of this web server (amongst others) and, whilst the web server can be browsed externally, the Java app fails to launch correctly and throws the errors below. Can anyone offer clues as to what additional config I many have to add to Nginx to get this working?

Globals are bad! But should I use them in this context?

- by Matt

Would setting the $link to my database be one thing that I should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is in the global scope would be wise. I am currently using the functions to transfer it back and forth so that way I do not have it in the global scope. But it is a bit of a hindrance to my script. Please advise.

Team build of Web Projects generates App_web_xxxx.dll files and TFSBuild.Proj Script

- by Steve Johnson

Hi all, I have a web application that has some non-web projects as well. When using Web Deployment, a single assembly is generated for all the aspx.vb files. When using Team Build (TS 2008), a lot number App_Web_xxx.dll file(s) are generated instead of a single assembly. How can i solve this problem and change the TFSBuild.proj file so that it can generate a single Web Assembly instead of a lot number of assemblies. Please help. Thanks Edit: I guess thats because the MERGE operation is not occurring like it used to happen for Web Deployment Project in my solution. How can i enable MERGE of App_web_*.dll files into a single Web.dll assembly file and delete the satellite assemblies? Here is my code from TFSBuild.proj file: (MY web project is in Release|.NET Config and all other projects within the solution are in Release|Any CPU) true .\Debug true true Web true false .\Release true true Web true Please tell me what are the corrections i need to do.,

Referencing assemblies created with ILMerge in Visual Studio projects

- by Daniel Schaffer

I have a solution in Visual Studio with 5 projects. They are: Foo.Core: Core functionality Foo.Api: Generated code built on top of core Foo.Web: Web-specific extensions Foo.Web.Mvc: MVC-specific extensions Newtonsoft.Json: 3rd party library I want to use ILMerge to merge Foo.Core, Foo.Api and Newtonsoft.Json into a single assembly, called Foo. That's the easy part. The problem I'm running into is that Foo.Web and Foo.Web.Mvc both need to reference all three of the merged assemblies. If I reference the original assemblies, they will have invalid references after I do the ILMerge. If I reference the ILMerged assembly, I have to reference a debug assembly and then change it before I package everything up, which doesn't seem ideal. I've tried creating a project called Foo, which references the 3 merged assemblies and replaces its own output with the ILmerged assembly, but that doesn't seem to work at all. Is there a reliable way to do this?

Error CS0117: Namespace.A does not contain definition for Interface..

- by SnOrfus

I'm getting the error: 'Namespace.A' does not contain a definition for 'MyObjectInterface' and no extension method 'MyObjectInterface' accepting a first argument of type ... I've looked at this and this and neither seems to apply. The code looks like: public abstract class Base { public IObject MyObjectInterface { get; set; } } public class A : Base { /**/ } public class Implementation { public void Method() { Base obj = new A(); obj.MyObjectInterface = /* something */; // Error here } } IObject is defined in a separate assembly, but: IObject is in a separate assembly/namespace Base and A are in the same assembly/namespace each with correct using directives Implementation is in a third separate assembly namespace, also with correct using directives. Casting to A before trying to set MyObjectInterface doesn't work Specifically, I'm trying to set the value of MyObjectInterface to a mock object (though, I created a fake instead to no avail) I've tried everything I can think of. Please help before I lose more hair. edit I can't reproduce the error by creating a test app either, which is why I'm here and why I'm frustrated. @Reed Copsey: /* something */ is either an NUnit.DynamicMock(IMailer).MockInstance or a Fake object I created that inherits from IObject and just returns canned values. @Preet Sangha: I checked and no other assembly that is referenced has a definition for an IObject (specifically, it's called an IMailer). Thing is that intellisense picks up the Property, but when I compile, I get CS0117. I can even 'Go To Definition' in the implementation, and it takes me to where I defined it.

How do I store an array of a particular type into my settings file?

- by joebeazelman

For some reason, I can't seem to store an array of my class into the settings. Here's the code: var newLink = new Link(); Properties.Settings.Default.Links = new ArrayList(); Properties.Settings.Default.Links.Add(newLink); Properties.Settings.Default.Save(); In my Settings.Designer.cs I specified the field to be an array list: [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public global::System.Collections.ArrayList Links { get { return ((global::System.Collections.ArrayList)(this["Links"])); } set { this["Links"] = value; } } For some reason, it won't save any of the data even though the Link class is serializable and I've tested it.

FluentNHibernate SQLite configuration exception - after switching to .net4

- by stiank81

I get an exception thrown when trying to use Fluent to configure my NHibernate connection to SQLite. The code I use to configure is as follows: var cfg = Fluently.Configure(). Database(SQLiteConfiguration.Standard.ShowSql().UsingFile("MyDb.db")). Mappings(m => m.FluentMappings.AddFromAssemblyOf<MappingsPersistenceModel>()); _sessionFactory = cfg.BuildSessionFactory(); A HibernateException is thrown when BuildSessionFactory() is called, saying: Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4. It has an InnerException: Exception has been thrown by the target of an invocation. Which again has an InnerException: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Now - to me it sounds like it doesn't find System.Data.SQLite.dll, but I can't understand this. Everywhere this is referenced I have "Copy Local", and I have verified that it is in every build folder for projects using SQLite. I have also copied it manually to every Debug folder of the solution - without luck. What can be causing this? Any ideas? My suspicion is that it is related to .Net4 somehow. The reason is that it worked just fine when I used .Net3.5, and then I changed to .Net4, and the problem started. You can also check out this other question for a more general approach towards Fluent-.Net4 compatibility.

Memcached and Rails Fragment Caching Issue

- by Michael Waxman

When I have 2 views that fragment cache the same query BUT display them differently, there is only one fragment and they both display it the same way. Is there any way around this? For example... #views/posts/list - cache(@posts) do - for p in @posts = p.title #views/posts/list_with_images - cache(@posts) do - for p in @posts = p.title = p.content = image_tag(p.image_url) #controllers/posts_controller def list ... @posts = Post.all end def list_with_images ... @posts = Post.all end

Caching web API proxy?

- by Jeremy Dunck

I was wondering if anyone knows of a caching proxy specifically for dealing with API responses? Ideally, I'd be able to declare what caching policy to use for different API semantics, e.g. cache album art for 1 day, cache favorite tweets for 5 minutes, cache map tiles forever, except invalidate when this other API is called. I know about using Apache, Squid, etc for caching in general -- I'm just hoping for something with nicer usage semantics by restricting the design goal to dealing with APIs rather than the web in general.

Silverlight WCF service consuming inherited types in datacontract

- by RemotecUk

Hi, Im trying to consume a WCF service in silverlight... What I have done is to create two seperate assemblies for my datacontracts... Assembly that contains all of my types marked with data contracts build against .Net 3.5 A Silverlight assembly which links to files in the 1st assembly. This means my .Net app can reference assembly 1 and my silverlight app assembly 2. This works fine and I can communicate across the service. The problems occur when I try to transfer inherited classed. I have the following class stucture... IFlight - an interface for all types of flights. BaseFlight : IFlight - a baseflight flight implements IFlight AdhocFlight : BaseFlight, IFlight - an adhoc flight inherits from baseflight and also implements IFlight. I can successfully transfer base flights across the service. However I really need to be able to transfer objects of IFlight across the interface as I want one operation contract that can transfer many types of flight... public IFlight GetFlightBooking() { AdhocFlight af = new AdhocFlight(); return af; } ... should work I think? However I get the error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error." Any ideas would be appreciated.

Error building Visual Studio 2010 Silverlight 4 projects on Windows 7 with XP Mode

I installed Visual Studio 2010 Beta 2 in an XP Mode VM on Windows 7. Then I created a trivial Silverlight 4 (beta) project and tried to build it. I get the following error: Error 1 The "ValidateXaml" task failed unexpectedly.

Anyone know how to fix it?

How to properly combine two files in XAML in Microsoft Blend?

- by MartyIX

Hello, I have a test project with the file MainWindow.xaml with the content: <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" xmlns:view="clr-namespace:Sokoban.View;assembly=Solvers" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <ad:DockingManager x:Name="dockingManager"> <ad:ResizingPanel Orientation="Vertical"> <view:Solvers x:Name="solvers" diag:PresentationTraceSources.TraceLevel="High" />   </ad:ResizingPanel> </ad:DockingManager> </Window> and in another project I have the file Solvers.xaml: <ad:DocumentPane x:Class="Sokoban.View.Solvers" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Name="GamesDocumentPane" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> </ad:DocumentPane> When I open my Visual Studio solution in Microsoft Blend 4 then I see the error: InvalidOperationException: DocumentPane must be put under a DockingManager! when I open either MainWindow.xaml or Solvers.xaml. It is all right in Solvers.xaml because there really is no DockingManager but MainWindow.xaml should work, shouldn't it? How to solve the problem? Note: It seems to me that the files are processed separately and because the file Solvers.xaml contains the error the MainWindow.xaml file also contains the very same error. Note 2: XAML files use AvalonDock library Is there a way how to say that Solvers.xaml is only an extension of another file? Thank you for any help!

How can I use non-Silverlight assemblies in a Silverlight app?

I'm working an project (pure hobby, "Sharping my skills") which has one unified back-end and multiple front-ends (ASP.NET MVC 1.0/JQuery and Silverlight 2). When I try to add reference to my business layer assembly in the Silverlight 2 project (VS2008); It gets rejected, because it's not a Silverlight assembly. Is their a way to include and reference a non-Silverlight assembly in a Silverlight app?

Terracotta With Hibernate and EHCache

- by Joe Biron

Head swimming with the product name soup at http://www.terracotta.org. Need someone to help clarify what I need. Background: app has some "legacy" persistence code that does not use Hibernate, but has a home-grown cache implementation. New entities are Hibernate enabled. What I want: to use Terracotta for Hibernate 2nd level cache. I think I then want to slide out the home-grown cache impl and slide in ehcache (very similar semantically to home-grown version) - obviously I want Terracotta to back that EHCache as well. Confused with: Will I be telling Hibernate that ehcache is it's cache provider, then configure ehcache to use terracotta? So (hibernate | legacy-persistence)- ehcache - terracotta Am I on the right track? Forgive the newb question but the terracotta.org site really confuses me since so much of it it trying to sell me the commercial varieties.

Reference a internal class from a Windows Workflow Activity

- by Ben Hughes

I'm creating a custom Workflow activity for use within TFS2010. In the same assembly I have a XAML activity and a C# code activity. The XAML activity references the code activity. When the assembly is deployed to our clients, I only want them to be able to use the Workflow activity. The code activity is of little use by itself and would no doubt confuse them. I thought the logical way to do this would be to set the code activity class to internal: the XAML is in the same assembly and should be able to access it. However, when I do that I get an error in the XAML saying that the assembly can't be found. Is there a way to make activities internal/hidden?

Strange behavior with Powershell scriptblock variable scope and modules, any suggestions?

- by DanMan

NOTE: I'm using PowerShell 2.0 on Windows Vista. I'm trying to add support for specifying build arguments to psake, but I've run into some strange PowerShell variable scoping behavior dealing specifically with calling functions that have been exported using Export-ModuleMember (which is how psake exposes it's main method). Following is a simple PowerShell module to illustrate (named repoCase.psm1): function Test { param( [Parameter(Position=0,Mandatory=0)] [scriptblock]$properties = {} ) $defaults = {$message = "Hello, world!"} Write-Host "Before running defaults, message is: $message" . $defaults #At this point, $message is correctly set to "Hellow, world!" Write-Host "Aftering running defaults, message is: $message" . $properties #At this point, I would expect $message to be set to whatever is passed in, #which in this case is "Hello from poperties!", but it isn't. Write-Host "Aftering running properties, message is: $message" } Export-ModuleMember -Function "Test" To test the module, run the following sequence of commands (be sure you're in the same directory as the repoCase.psm1): Import-Module .\repoCase.psm1 #Note that $message should be null Write-Host "Before execution - In global scope, message is: $message" Test -properties { "Executing properties, message is $message"; $message = "Hello from properties!"; } #Now $message is set to the value from the script block. The script block affected only the global scope. Write-Host "After execution - In global scope, message is: $message" Remove-Module repoCase The behavior I expected was for the script block I passed to Test to affect the local scope of Test. It is being 'dotsourced' in, so any changes it makes should be within the scope of the caller. However, that's not what's happening, it seems to be affecting the scope of where it was declared. Here's the output: Before execution - In global scope, message is: Before running defaults, message is: Aftering running defaults, message is: Hello, world! Executing properties, message is Aftering running properties, message is: Hello, world! After execution - In global scope, message is: Hello from properties! Interestingly, if I don't export Test as a module and instead just declare the function and invoke it, everything works just like I would expect it to. The script block affects only Test's scope, and does not modify the global scope. I'm not a PowerShell guru, but can someone explain this behavior to me?

Problem with SQLite related nUnit-tests after upgrade to VS2010 and Re#5

- by stiank81

After converting to Visual Studio 2010 with ReSharper5 some of my unit tests started failing. More specifically this applies to all unit tests that use NHibernate with SQLite. The problem seem to be related to SQLite somehow. The unit tests that does not involve NHibernate and SQLite are still running fine. The exception is as follows: NHibernate.HibernateException : Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4. ----> System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation. ----> NHibernate.HibernateException : The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use <qualifyAssembly/> element in the application configuration file to specify the full name of the assembly. TearDown : System.NullReferenceException : Object reference not set to an instance of an object. The exception is the NullReferenceException on TearDown when cleaning up NHibernate objects that wasn't successfully created, but the problem seem to be related to SQLite somehow. I run my unit tests through ReSharper, but I get the same exception when running them directly through the NUnit.exe application. However, running them through the x86 variant (NUnit-x86.exe) all tests run fine. Can it be related to some mixing of 64bit and 32bit dlls? It still runs fine through VS2008 + ReSharper4.5. Note that the target framework of my projects still is .NET3.5. Anyone seen this problem before?

How to document an accessor/mutator method in phpDoc/javaDoc?

- by nickf

Given a function which behaves as either a mutator or accessor depending on the arguments passed to it, like this: // in PHP, you can pass any number of arguments to a function... function cache($cacheName) { $arguments = func_get_args(); if (count($arguments) >= 2) { // two arguments passed. MUTATOR. $value = $arguments[1]; // use the second as the value $this->cache[$cacheName] = $value; // *change* the stored value } else { // 1 argument passed, ACCESSOR return $this->cache[$cacheName]; // *get* the stored value } } cache('foo', 'bar'); // nothing returned cache('foo') // 'bar' returned How do you document this in PHPDoc or a similar automated documentation creator? I had originally just written it like this: /** * Blah blah blah, you can use this as both a mutator and an accessor: * As an accessor: * @param $cacheName name of the variable to GET * @return string the value... * * As a mutator: * @param $cacheName name of the variable to SET * @param $value the value to set * @return void */ However, when this is run through phpDoc, it complains because there are 2 return tags, and the first @param $cacheName description is overwritten by the second. Is there a way around this?

Setting refresh-policies in Ehcache

- by Alex Ciminian

Is there any to specify a data refresh policy in Ehcache? I am currently migrating an application from OSCache to Ehcache and I can't seem to find any way to specify when an element needs refreshing, besides setting timeToIdle and timeToLive. What I want is: on accessing an element from the cache, check with it's associated resource to see if it was updated later than the lastUpdateTime of the cache element. If yes, refresh the cache; else serve the content from the cache. In OSCache this was done by catching NeedsRefreshExceptions and setting custom refresh policies for the elements. I've been digging around in the docs for a while now, but I wasn't able to find any methods or examples of how I could accomplish this in Ehcache. Any help would be appreciated :). Alex

Can I read AssemblyFile information in Inno Setup

- by Nifle

I would like to read these three values from my application.exe in my Inno Setup script. [assembly: AssemblyCompany("My Company")] [assembly: AssemblyProduct("My Great Application")] [assembly: AssemblyFileVersion("9.3.2")] Does anyone know how this might be accomplished? I know I can get the last one using GetFileVersion("path/to/greatapp.exe") is there something similar for the first two?
