• Silverlight: Why can't silverlight see my xaml file referenced in MergedDictionary?

  - by Sergio

  Hi there, I have a silverlight application with a number of styles defined in a seperate xaml file under the directory /Styles. My App.xaml looks like this: <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/Styles/Legend.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> Legend.xaml has its build action set to Content and 'Do Not Copy' as the copy to output directory setting. The message I'm getting in blend is: An error occurred while finding the resource dictionary "/Styles/Legend.xaml" Thanks in advance!

• XAML trigger as StaticResource

  - by adrianm

  Why can't I create a trigger and use it as a static resource in XAML? <Window.Resources> <Trigger x:Key="ValidationTrigger" x:Shared="False" Property="Validation.HasError" Value="true"> <Setter Property="FrameworkElement.ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)/ErrorContent}"/> </Trigger> <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"> <Style.Triggers> <StaticResource ResourceKey="ValidationTrigger"/> </Style.Triggers> </Style> </Window.Resources> I get an errormessage at runtime "Value cannot be null. Parameter name: triggerBase Error at object 'System.Windows.Markup.StaticResourceHolder' in markup file"

• Java webapp: adding a content-disposition header to force browsers "save as" behavior

  - by WizardOfOdds

  Even though it's not part of HTTP 1.1/RFC2616 webapps that wish to force a resource to be downloaded (rather than displayed) in a browser can use the Content-Disposition header like this: Content-Disposition: attachment; filename=FILENAME Even tough it's only defined in RFC2183 and not part of HTTP 1.1 it works in most web browsers as wanted. So from the client side, everything is good enough. However on the server-side, in my case, I've got a Java webapp and I don't know how I'm supposed to set that header, especially in the following case... I'll have a file (say called "bigfile") hosted on an Amazon S3 instance (my S3 bucket shall be accessible using a partial address like: files.mycompany.com/) so users will be able to access this file at files.mycompany.com/bigfile. Now is there a way to craft a servlet (or a .jsp) so that the Content-Disposition header is always added when the user wants to download that file? What would the code look like and what are the gotchas, if any?

• Maven grails plugin issue

  - by Jack

  I'm trying to create the pom for an existing grails project via: mvn grails:create-pom -Dourcompany.com Now, we have our maven repository available in a local nexus repo: http://ourcompany.com/nexus But when i run the above, i get the below error Downloading: http://ourcompany.com/nexus/content/groups/public/ourcompany/com/hibernate-core/3.3.1.GA/hibernate-core-3.3.1.GA.jar [INFO] Unable to find resource 'ourcompany.com:hibernate-core:jar:3.3.1.GA' in repository central (http://repo1.maven.org/maven2) [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR But it is in there at simply: http://ourcompany.com/nexus/content/groups/public/hibernate-core/3.3.1.GA/hibernate-core-3.3.1.GA.jar Ie, w/o the "ourcompany.com" path.

• SharePoint 2007 Central Admin w3wp.exe process consumin 99% CPU

  - by Matrich

  Hi, I have been running an intranet using SharePoint 2007 for over a year and all has been working fine. However, after some time, I realized that the intranet portal was slow. Trying to access the Central Admin over another computer not the SharePoint server also became an issue. So I logged onto the real SharePoint Server and it took some ages to login and then was so slow even on the server unlike other times. When I checked the Task Manager, I found out that w3wp.exe was consuming 99% of the CPU speed. When I restarted the Central Admin App Pool, everything came back to normal and all was running well but after a few minutes (15 or so), it again became slow. I have checked the Event Logs and nothing conclusive was there to help me out. Anyone who has had this experience? or has any good resource? Please help. Thanks in advance

• How to access MyProject.MySettings.Default.SomeSetting from xaml?

  - by Shimmy

  I have defined a StringCollection in the Project Settings. I want to use the values in a ComboBox. Is there a way to access it xamly? I tried: <CollectionViewSource Source="{x:Static src:MySettings.Default.MyCollection}" /> <CollectionViewSource x:Key="RoomSections" Source="{x:Static src:MySettings.Default.RoomSections}" /> *src is the xmlns of the project It says: "Type src:MySettings.Default was not found". The thing is that MySettings is a class that offers a Default property which is a thread-safe instance of MySettings, I really want to get the collection from the Default property and not by instantiating a new on. Is there other ways I am not aware of, maybe ObjectDataProvider can access static objects? I thought, maybe I can make in the App.xaml a global resource that return MySettings.Default which is an instance of the MySettings class, and then access all its properties, I will try that out, but I prefer the easy way.

• What parts of .NET require administrative priviliges to be executed?

  - by Ruben Steins

  Which parts of the framework require a user to be more than a Standard User? The reason I'm asking is because I'm trying to compile a list of possible issues with our existing applications when migrating to Windows 7. Now, I can think of a few things myself: Writing to Eventlog Writing to Registry Keys outside of Current_User scope Getting an Environment variable etc... I really would like a more complete list and so far I've not come across a decent resource in which all this stuff is listed. Note that I'm not looking for ways of elevating the priviliges for the exsiting apps (which can be done by using a manifes), I'm simply idenitifying actions in code that might cause issues.

• Problem creating ObjectContext from different project inside solution.

  - by Levelbit

  I have two projects in my Solution. One implements my business logic and has defined entity model of entity framework. When I want to work with classes defined within this project from another project I have some problems in runtime. Actually, the most concerning thing is why I can not instantiate my, so called, TicketEntities(ObjectContext) object from other projects? when I catch following exception: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. I found out it's brake at: public partial class TicketEntities : global::System.Data.Objects.ObjectContext { public TicketEntities() : base("name=TicketEntities", "TicketEntities") { this.OnContextCreated(); } with exception: Unable to load the specified metadata resource. Just to remind you everthing works fine from orginal project.

• CRM 2011 XAML Workflows in VS 2012

  - by AlexR

  I'm writing this knowing there's another topic like this to be found here the answer provided however does not make much sense to me and whatever I tried doesn't seem to work so I'm seeking clarification. The situation is as follows: * New CRM 2011 toolkit solution * New project added for Xaml workflow * Adding CRM "Workflow" activity causes error The error: It shows a redbox "Could not generate view for Workflow" The Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.IO.IOException: Cannot locate resource 'workflowdesigner.xaml' I have VS 2012 SP2 with the latest (June) CRM SDK Toolkit installed. I did a clean install of the toolkit so it's not "upgraded" to prevent any old assemblies being referenced. I tried the things from the referenced question and moved the assemblies over and also re-referenced the latest assemblies to make sure everything works fine. I also tried downloading a workflow XAML created in CRM and opening but it gives the same error. I also opened the "example" workflow XAML solution in the SDK, again same result.

• What does "Unatuthorized zone" mean when browsing xsd files with Visual Studio 2010?

  - by starskythehutch

  When I open up an xsd file that includes other xsd files, all of the included files are added to a section called "Unauthorized zone". Visual Studio highlights the element and gives the following error when trying to resolve the schemaLocation attribute: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've read the following blog post, but I'm not familiar enough with xsd yet to fully understand it. Can anyone explain why this is happening or point me to a good resource that can help?

• Can't create blob container on Azure Blob Storage

  - by desautelsj

  The following code throws an error on the "CreateIfNotExist" method call. I am attempting to connect to my Azure Blob storage and create a new container called "images" var storageAccount = new CloudStorageAccount( new StorageCredentialsAccountAndKey("my_account_name", "... my shared key ..."), "https://blob.core.windows.net/", "https://queue.core.windows.net/", "https://table.core.windows.net/" ); var blobClient = storageAccount.CreateCloudBlobClient(); var blobContainer = blobClient.GetContainerReference("images"); blobContainer.CreateIfNotExist(); The error is: [StorageClientException: The requested URI does not represent any resource on the server.] The "images" container does not exist but I was expecting it to be created instead of an error to be thrown. What am I doing wrong? I have tried HTTP instead of HTTPS but the result is the same error.

• Any hosted versions of jQuery that have the 'Access-Control-Allow-Origin: *' header set?

  - by Greg Bray

  I have been working with jQuery recently and ran into a problem where I couldn't include it in a userscript because xmlhttpRequest uses the same origin policy. After further testing I found that most browsers also support the Cross-Origin Resource Sharing access control defined by W3C as a workaround for issues with same origin policy. I tested this by hosting the jQuery script on a local web server that included the Access-Control-Allow-Origin: * http header, which allowed the script to be downloaded using xmlhttpRequest so that it could be included in my userscript. I'd like to use a hosted version of jQuery when releasing the script, but so far testing with tools like http://www.seoconsultants.com/tools/headers I have not found any sites that allow cross-origin access to the jQuery script. Here is the list I have tested so far: http://www.asp.net/ajaxlibrary/CDN.ashx http://code.google.com/apis/ajaxlibs/documentation/index.html#jquery http://docs.jquery.com/Downloading_jQuery#CDN_Hosted_jQuery Are there any other hosted versions of jQuery that do allow cross origin access?

• How to set locale default_url_options for functional tests (Rails)

  - by insane.dreamer

  In my application_controller, I have the following set to include the locale with all paths generated by url_for: def default_url_options(options={}) { :locale => I18n.locale } end My resource routes then have a :path_prefix = "/:locale" Works fine on the site. But when it comes to my functional tests, the :locale is not passed with the generated urls, and therefore they all fail. I can get around it by adding the locale to the url in my tests, like so: get :new, :locale => 'en' But I don't want to have to manually add the locale to every functional test. I tried adding the default_url_options def above to test_helper, but it seems to have no effect. Is there any way I can change the default_url_options to include the locale for all my tests? Thanks.

• Accessing a file in Windows and Linux when working with JAVA+Eclipse.

  - by Gabriel A. Zorrilla

  Hi there. I'm doing some JAVA coding at home and at work. At home i have Linux, work, Windows. The rootpath to X file in Windows is c:\Documents And Settings\User\My Documents\Dropbox\file.xxx and in Linux is something like /media/My Documents/Dropbox/file.xxx So, every time i edit in either system, i have to manually change the root of the file in a new File(FILEPATH) statement. Is there a workaround for this? I bet if the file root is relative to the project resource tree would do the trick, but that's an Eclipse based solution, not JAVA, i believe.

• Google Chrome Speed Tracer what does Request Timing and Response Timing actually measure?

  - by Bryce Thomas

  I'm testing out the Google Chrome Speed Tracer on a few common web pages and taking a look through the results. One thing I'm not sure I understand is what the "Request Timing" and "Response Timing" properties of resources are actually measuring. Initially I thought Request Timing must measure the time from a request for a resource being sent and when that request arrived at the server. However, I then wondered how the Speed Tracer would actually have any way of measuring this. Furthermore, the Response Timing that I'm getting for resources tends to be far less than the Request Timing (e.g. 500ms request, 1ms response), which is a little bit suss. So is anyone able to explain exactly what Request Timing and Response Timing are measuring?

• EJB3 Business Delegates

  - by mykola

  Is there any reason for making delegate when using EJB3? Because the only real benefit i see from delegate is that it allows to hide lookup and access details of EJB architecture. Well it also provides some decoupling but it's mostly unused, imho. With EJB3 we have injection so now i can just create a variable with @EJB annotation and use it as is. Do i still need delegates? Is this injection resource consuming? I mean if i use it in JSF's request managed beans may be it's still better to use delegates just to lessen these injection calls? Thank you!

• Algorithm and data structure learning resources for dynamic programming

  - by Pranav

  Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

• How do you fix TSD02016 error in Database

  Howdy, I have a database I am using the Visual Studio 2010 Database Project tool vsdbcmd.exe to create a schema from. vsdbcmd /a:Import /dsp:Sql /model:"Database" /cs:"Server=SqlServer; Initial Catalog=DatabaseName; Integrated Security=SSPI;" The tool is reporting an error: Error TSD02016, Gen-259 (12,50) The column name is not valid. No table name was specified. How would I go about pinpointing where this error is originating? I have found one resource on the internet (http://social.msdn.microsoft.com....) that points to a possibility of a keyword used incorrectly, but the error messages are not the same. What is Gen-259?

• Assinging a GD reference to a new variable fails to copy

  - by Stomped

  This is a contrived example, but it illustrates my problem much more concisely then the code I'm using - and I've tested this and it exhibits the problem: $image = imagecreatefromjpeg('test.jpg'); $copy_of_image = $image; // The important bit imagedestroy($image); header('Content-type: image/jpeg'); imagejpeg($copy_of_image); Now, my expectation is that $copy_of_image is exactly that, but when I run this, it fails, printing out the URL of the script of all things. Comment out the imagedestroy() and it works just fine. a var_dump of $image provides: resource(3) of type (gd) So why can't I copy this? Apparently the assignment $copy_of_image = $image is creating a reference rather then a copy - is there a way to prevent that?

• My C# and DLL Data Woes

  - by Lynn

  Hey guys, I'm a very beginner C# coder. So, if I get some of the terms incorrect, please be easy on me. I'm trying to see if it is possible to pull data from a DLL. I did some research and found that you can store application resources within a DLL. What I couldn't find, was the information to tell me how to do that. There is a MS article that explains how to access resources within a satellite DLL, but I honestly don't know if that is what I'm looking for. http://msdn.microsoft.com/en-us/library/ms165653.aspx I did try some of the codes involved, but there are some "FileNotFoundExceptions" going on. The rest of the DLL information is showing up: classes, objects, etc. I just added the DLL as a resource in my Visual Studio Project and added it with "using". I just don't know how to get at the meat of it, if it is possible. Thanks, Lynn

• Can I check the validity of a single DataMapper property?

  - by Nathan Long

  In a custom DataMapper setter, I'd like to check whether the value I'm setting is valid or not. For instance: class ToastMitten include DataMapper::Resource property :id, Serial property :wearer, Enum['Chuck Norris', 'Jon Skeet'] property :first_worn_at, DateTime def wearer=(name) super if wearer.valid? # How can I do this? first_worn_at = Time.now end end end t = ToastMitten.new t.wearer = 'Nathan Long' # invalid value; do NOT set first_worn_at t.wearer = 'Jon Skeet' # valid value; set first_worn_at Can I check the validity of a single property like this without calling valid? on the object itself and looking through all the errors?

• Rails routes direct index action to show action
