• Wrong assembly-references for Silverlight Sketchflow project in Blend 3

  - by persistent

  Hello, In my installation of Blend 3, the SketchStyles are missing when a new project is created. I found out that this is because the following automatic references in the project are wrong: Microsoft.Expression.Interactions Microsoft.Expression.Prototyping.Interactivity Microsoft.Expression.Prototyping.RunTime Microsoft.Expression.Prototyping.SketchControls In the project references these all point to my project path (where they don't live). If I remove them manually, and instead set the references to ie this: "c:\Program Files (x86)\Microsoft SDKs\Expression\Blend 3\Interactivity\Libraries\Silverlight\Microsoft.Expression.Interactions.dll" everything works. Any ideas on why, and how to fix this? Could it be the project template somehow? TIA

• Some special characters defined in "ISO-8859-1" can't be shown when encoding with "UTF-8"

  - by Mike.Huang

  I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters after 0x80 (in "ISO-8859-1") not been shown when converted to "UTF-8" from "ISO-8859-1". Any other method can solve this query?

• Is it possible to make a button on an AlertDialog that doesn't automatically close the dialog?

  - by Parker

  I have a simple list view with some check boxes in an alert dialog. I need to option to add a select all/none but you can't bring up the menu in an alert dialog, and I want to do this function from a button. From what I've seen any kind of button (positive, neutral, and negative) all close the dialog regardless. So, is this possible? If no, what alternatives do I have? My last mitigation is to simply create a new view and recreate everything. Is a new view the best solution?

• MooTools Sortables with horizontal list having problems

  - by Anurag

  I am having problems sorting list items using the Sortables class when the list items are displayed horizontally. Removing this style fixed everything: display: inline Created an example on jsfiddle. This works. Check the stylesheet for .countries li - it does not display the list inline - http://jsfiddle.net/Wgpqw/ This does not work properly. I can drag the list items around the list, but the sort randomly happens when moving around - http://jsfiddle.net/Wgpqw/1/ I suspect it has something to do with the list element positioning in inline mode. Any help is greatly appreciated.

• Classes missing if application runs for a long time

  - by Rogach

  I have a funny problem - if my application runs for a long time ( 20h), then sometimes I get NoClassDefFound error - seems like JVM decided that the class is not going to be used anyway and GCd it. To be a bit more specific, here's an example case: object ErrorHandler extends PartialFunction[Throwable,Unit] { def isDefinedAt(t: Throwable) = true def apply(e: Throwable) =e match { // ... handle errors } } // somewhere else in the code... try { // ... long running code, can take more than 20 hours to complete } catch (ErrorHandler) And I get the following exception: Exception in thread "main" java.lang.NoClassDefFoundError: org/rogach/avalanche/ErrorHandler$ If that try/catch block runs for smaller amounts of time, everything works as expected. If anyone is interested, here is the codebase in question: Avalanche I need to note that I saw this and similar problems only on Cent OS 5 machines, using JRE 6u26 and Scala 2.9.1 / 2.9.2. What could be the cause of this problem?

• Why can't sub-packages see package private classes?

  - by Polaris878

  Okay so, I have this project structure: package A.B class SuperClass (this class is marked package private) package A.B.C class SubClass (inherits from super class) I'd rather not make SuperClass publicly visible... It is really just a utility class for this specific project (A.B). It seems to me that SubClass should be able to see SuperClass, because package A.B.C is a subpackage of A.B... but this is not the case. What would be the best way to resolve this issue? I don't think it makes sense to move everything in A.B.C up to A.B or move A.B down to A.B.C... mainly because there will probably be an A.B.D which inherits from stuff in A.B as well... I'm a bit new to Java, so be nice :D (I'm a C++ and .NET guy)

• Insert an ajaxified Webpart into an existing MOSS site

  - by mamoo

  Hi everybody, I need to code a webpart which purpose is to asynchronously fetch some documents and display them into an existing page. Unfortunately I have to face a lot of rescritcions and my struggle to find a solution seems useleess so far. 1) I cannot use Microsoft asp.net ajax 2) I must use Jsonp because the called service (page, whatever...) is outside the site's domain. That's not a big problem. 3) I have no possibility to alter the existing page code, so I cannot reference an external library such as JQuery. 4) For the same reason I have no possibility to call my methods on the window.onLoad event, so here the question is: how can I be sure that everything is correctly loaded before triggering my ajax call? 5) Since several instances of the same webpart can be placed into the same page, can there be some possible conflicts among the various js functions?

• How should I deploy a patch to a Passenger-based production Rails application without downtime?

  - by Olly

  I have a Passenger-based production Rails application which has thousands of users. Occasionally we need to apply a code patch (we use git) and the current process for doing this (you can assume there are no data migrations) is: Perform git pull origin [production-branch-name] on the server touch tmp/restart.txt to restart Passenger This allows us to patch the server without having to resort to putting up a maintenance page, which is great, but it doesn't feel quite right since it's not actually a proper 'deployment', and we still need to manually update the revision file and our deployment doesn't appear in the Hoptoad or NewRelic services we use. Ideally I would run cap production deploy and just let the standard Capistrano deployment script take care of everything, but is this a dangerous thing to do without putting up a maintenance page? This deployment process seems to be fairly safe in that the new revision is deployed to a completely separate folder and only right at the end of the process is a symlink re-created to switch the currently deployed version, but I'm still fairly paranoid about this somehow resulting in a lost or failed request.

• How to get "paster request" to use config host value instead of localhost?

  - by mmartinez

  I'm trying to access my pylons application via cron job to send notifications to my users. The way I'm doing this is by running the application using something like: paster request myconfig.ini /maintenance/do In the actual controller I check for the "paste.command_request" to block public access. Everything works but the only problem is that within the notifications that I send to my users there is a link to their profile and the host is "localhost" which should instead be the domain name of the application. When the notifications are sent from within the served application (say, a user modifies their settings on the site) the notifications have the correct url. I am using mako to render my email tamplates and within the template I am using the "pylons.url" method with "qualified" set to "True". Am I missing something here? Thanks in advance.

• ASP.NET MVC and ApplicationPath

  - by user93422

  Question is about paths and domains: I have an out-of-the box ASP.NET MVC project (generated by "File-New Project"). On LogOn page it does: return Redirect("~/Account/LogOn");. I have a domain name: mycompany.com, and following file structure on the server: /Root /MyApp (this is where my app goes into) Default.aspx ... I have set up following domain pointer: mycompany.com -> \MyApp When I go to mycompany.com I get an error, something about can't find mycompany.com/MyApp/MyApp/Account/LogOn Question: Where does second /MyApp path element comes from? Note: If I don't use domain pointer and deploy the site to the root - everything works just fine. Note: My hosting provider is webhost4life.com.

• VS2010 profiler/leak detection

  - by Noah Roberts

  Anyone know of a profiler and leak detector that will work with VS2010 code? Preferably one that runs on Win7. I've searched here and in google. I've found one leak detector that works (Memory Validator) but I'm not too impressed. For one thing it shows a bunch of menu leaks and stuff which I'm fairly confident are not real. I also tried GlowCode but it's JUST a profiler and refuses to install on win7. I used to use AQtime. It had everything I needed, memory/resource leak detection, profiling various things, static analysis, etc. Unfortunately it gives bogus results now. My main immediate issue is that VS2010 is saying there are leaks in a program that had none in VS2005. I'm almost certain it's false positives but I can't seem to find a good tool to verify this. Memory Validator doesn't show the same ones and the reporting of leaks from VS doesn't seem rational.

• Invert bitmap colors

  - by Alex Orlov

  I have the following problem. I have a charting program, and it's design is black, but the charts (that I get from the server as images) are light (it actually uses only 5 colors: red, green, white, black and gray). To fit with the design inversion does a good job, the only problem is that red and green are inverted also (green - pink, red - green). Is there a way to invert everything except those 2 colors, or a way to repaint those colors after inversion? And how costly are those operations (since I get the chart updates pretty often)? Thanks in advance :) UPDATE I tried replacing colors with setPixel method in a loop for(int x = 0 ;x < chart.getWidth();x++) { for(int y = 0;y < chart.getHeight();y++) { final int replacement = getColorReplacement(chart.getPixel(x, y)); if(replacement != 0) { chart.setPixel(x, y, replacement); } } } Unfortunetely, the method takes too long (~650ms), is there a faster way to do it, and will setPixels() method work faster?

• rails nested attributes

  - by user342798

  I am using rails 3.0.0.beta3 and I am trying to implement form with nested attributes using :accepts_nested_attributes_for. My form is nested to three levels: Survey Question Answer. Survey has_many Questions, and Question has many Answers. Inside the Survey model, there is :accepts_nested_attributes_for :questions and inside the question mode, there is :accepts_nested_attributes_for :answers Everything is working fine except when I add a new answer to an existing question, it doesn't get created. However, if I make changes to the corresponding question while creating the answer, I can successfully create the answer. This example is exactly similar to a railscast: http://railscasts.com/episodes/197-nested-model-form-part-2 but doesn't work in rails3 (at least in my case). Please let me know if there is any issue with nested attributes in Rails 3. Thanks in advance.

• ASP.NET Excel Export formatting question

  - by BWC

  Hey Guys, I've been banging my head on the wall over this issue for a couple days now and I need some help. I'm creating an excel file using ASP.net and everything is going just fine except one column has to be formatted as a decimal to 2 places but when it pulls into excel, excel automatically formats it as a whole number instead of keeping the decimal places. sw.Write(String.Format("{0:f}", CDbl(dr(14)).ToString("0.00"))) this produces "20.00" but when I open it in excel it's displayed as 20...if I select the whole column and format it as a number it gets displayed as 20.00 like it's supposed to but I don't want to have to do this (I can't do that) the file is supposed to be automatically picked up and imported into another system that needs the column to be a decimal. Any suggestions would be greatly appreciated.

• cakePHP - ACL tutorial & SQL Error: 1104

  - by vector

  Greetings! I run into a problem/bug in production environment with SQL Error: 1104 when deploying a project secured with the ACL tutorial. The full error: SQL Error: 1104: The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay [CORE/cake/libs/model/datasources/dbo_source.php, line 666] I've build a small site, worked through the ACL tutorial from the official cake book and locally everything is spiffy. dev. setup consists of: XAMPP: myslq 5.1.33, php 5.3 cakePHP 1.2.7 prod. setup: mysql 5.0.33 php 5.2.2 One of the differences I noticed with mysql setup between local and production servers, is that SQL_BIG_SELECTS is disabled on the production server ( and I don't have privileges to change that, posted a support ticked, didn't hear anything yet) Is there anything I can do about this from my end? Thanks in advance.

• php POST and non-english language chars passes empty

  - by haim evgi

  I'm trying to program a Hebrew site with a search option. (old site and the charset of this site is windows-1255) I am using php 5.2 with Apache 2.2, on a Debian 5 (Lenny) with appropriate code pages enabled. I am using _POST to pass arguments to a script. If I pass English word to the script everything works, but when I use Hebrew nothing is passed through the POST function. When I use ECHO to show _POST, the variable is empty. What might be the problem? P.S. this is old site that worked fine on PHP 4 with debian 4, and the problem arised only after we upgrade to PHP5+debian5.

• UIViewControllers - TabBarApplication - iPhone SDK

  - by Kevin

  Hello everyone, I am very new to the iPhone SDK. I need to know if in a tab bar application I need to make UIViewController classes. For example, when I make a new tab bar application there is a default FirstViewController class (.h, .m) already there. Now if I have code on the second tab, would I need to create a SecondViewController class? If not, how would I make a button on the 2nd tab, and make that button do something. I'm not really sure how to do it, because the FirstViewController works with the buttons and code, but if I make a SecondViewController, and I link everything my app crashes. If anyone could help it would be greatly appreciated. Kevin

• Django, Redirecting staff from login to the admin site.

  - by Francisco Gomez

  So my site basically has 2 kinds of ways to login, one of them is for the common users, who get the regular screen that asks them for username and password, the other way its for staff. The staff login should redirect them to the admin site after logging in, but for some reason the redirect doesnt happen, it stays on the same login page. I use this condition on the login view. if user is not None and user.is_active and user.is_staff: auth.login(request,user) return HttpResponseRedirect("/admin/") The admin site its up and running in my url configuration and everything, but i dont know if this is the correct way to redirect to the admin site already on session. Thanks, any help would be appreciated.

• combining two select statements to return one result

  - by DalivDali

  I need to combine the results for two select queries from two view tables, from which I am performing calculations. Perhaps there is an easier way to perform a query using if...else - any pointers? Essentially I need to divide everything by 'ar.time_ratio' under the condition in sql query 1, and ignore that for query 2. SELECT gs.traffic_date, gs.domain_group, gs.clicks/ar.time_ratio as 'Scaled_clicks', gs.visitors/ar.time_ratio as 'scaled_visitors', gs.revenue/ar.time_ratio as 'scaled_revenue', (gs.revenue/gs.clicks)/ar.time_ratio as 'scaled_average_cpc', (gs.clicks)/(gs.visitors)/ar.time_ratio as 'scaled_ctr', gs.average_rpm/ar.time_ratio as 'scaled_rpm', (((gs.revenue)/(gs.visitors))/ar.time_ratio)*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar WHERE ar.group_id=gs.domain_group and SELECT gs.traffic_date, gs.domain_group, gs.clicks, gs.visitors, gs.revenue, (gs.revenue/gs.clicks) as 'average_cpc', (gs.clicks)/(gs.visitors) as 'average_ctr', gs.average_rpm, ((gs.revenue)/(gs.visitors))*1000 as "Ecpm" FROM group_stats gs, v_active_ratio ar where not ar.group_id=gs.domain_group

• WCF issues with KnownType for Dictionary

  - by Tom Frey

  Hi, I have a service that implements the following DataMember: [DataMember] public Dictionary<string, List<IOptionQueryResult>> QueryResultItems { get; set; } I have the class "OptionQuerySingleResult" which inherits from IOptionQueryResult. Now, I understand that I need to make the OptionQueryResult type "known" to the Service and thus tried to add the KnownType in various ways: [KnownType(typeof(Dictionary<string, OptionQuerySingleResult[]>))] [KnownType(typeof(Dictionary<string, List<OptionQuerySingleResult>>))] [KnownType(typeof(OptionQuerySingleResult)] However, none of those approaches worked and on the client side I'm either getting that deserialization failed or the server simply aborted the request, causing a connection aborted error. Does anyone have an idea on what's the proper way to get this to work? I'd like to add, the if I change the QueryResultItems definition to use the concrete type, instead of the interface, everything works just fine. Thanks, Tom

• Webfaction: How do I run a Static/Perl app and Django app under the same website

  - by swisstony

  I have an existing Perl app that I'm moving to a Webfaction website. I will be adding Django apps to this Webfaction website too. I would like the Django app to get first call and so would want its URL path to be / This would allow me to add any new URLs to the urls.py I wish as my app grows. If the URL doesn't match anything in the urls.py I would like it to get passed to the static Perl app. For example /app1 - Django /app2 - Django Everything else not picked up by urls.py I would want going to my Perl app For example: /index.html - Static/Perl app /about.html - Static/Perl app /contact.html - Static/Perl app /apps/perlapp1.cgi - Static/Perl app etc How do I go about achieving this in Webfaction?
