• jQuery .each or search function, how can I make use of those?

  - by Noor

  I have a ul list, with 10 items, and I have a label that displays the selected li text. When I click a button, I need to check the label, versus all the list items to find the matching one, when it finds that I need to assign the corresponding number. I.e. list: Messi Cristiano Zlatan hidden values of list items: www.messi.com www.cronaldo.com www.ibra.com label: Zlatan script (thought)procces: get label text, search list for matching string, get the value of that string. (and if someone could point me in a direction to learn these basic(?) stuff. tried to be as specific as possible, thanks guys!

• SForceAPI : unable to find classes listed on API? (Account, Contact, etc)

  - by Firefox

  Hi, API referred : http://www.salesforce.com/us/developer/docs/api/index.htm subsection: reference-standard objects Client side details : partner.wsdl, Axis2 1.5, generated stubs using unpacked option (-u). I was hoping to find some basic objects like Account, Contact, etc (which were listed on above url) so that I can do something like - SObject[] sObjArray = queryResult.getRecords(); for(SObject sObj : sObjArray){ Account acc = [Account] sObj; } [used above approach successfully in another webservice - 'Zuora'] However, I could not find Account class in the generated classes. I guess I am into wrong approach, but atleast I should be finding the classes listed in the reference API. Please help.

• protecting my web page and folder from external using .htaccess and .htpassword in php

  - by Testadmin

  Hai I want to protect a folder (protect) and the files inside that folder. I have created a .htaccess file and put the following code. AuthName "Myfolder" AuthType Basic AuthUserFile url/protect/.htpasswd Require valid-user Also created a .htpassword file which contain username:password When I run my URL http://localhost/url/protect, I got a pop up asking username and password, I entered username as username and password as password. After that I got an error page "server error 500" "The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script. If you think this is a server error, please contact the webmaster." Why this happened?. Any thing wrong here? Anything needs to see my pages under the folder. Please give me the answer.

• Favouriting things in a database - most efficient method of keeping track?

  - by a2h

  I'm working on a forum-like webapp where I'd like to allow users to favourite an item so that they can keep track of it, and also so that others can see how many times an item's been favourited. The problem is, I'm unsure on the best practices for databases, which includes this situation. I have two ideas in my head on how to do this: Add an extra column to the user table and store things like so: "|2|5|73|" Add an extra table with at least two columns, one for referencing an item, the other for referencing a user. I feel uncomfortable about going for the second method as it involves an extra table, and potentially more queries would be required. Perhaps these beliefs aren't an issue, as I have little understanding of databases beyond simply working with table layouts and basic queries.

• Python Desktop Application with the Browser as an interface?

  - by Eli

  I want to create an application that runs on the users computer, a stand-alone application, with installation and what-not, but I want the interface to be a browser, either internal and displayed as an OS window or external accessible using the browser (i.e. some http server). The reason would be because I know a little about Python, but I think I can manage as long as I have some basic roots that I can use and manipulate, and those would be HTML, CSS, and Javascript. I've yet to find a good GUI tool which I can use, and always abandon the idea after trying to mess around and eventually not getting anything.

• Using Windows header files within Netbeans 6.8

  - by Matthieu Steffens

  I'm trying to make an windows application within Netbeans. When using Visual studio it is no problem to use files like tchar.h I have receaved a basic file structure containing those and I'm trying to get them to work on Netbeans IDE but it seems that Netbeans won't allow using files from Visual Studio. I have tried to add the tchar.h file and all other file it required (including some C++ core files) and commenting the errors written in those care files: #error ERROR: Use of C runtime library internal header file. But netbenas can't find the tchar.h file while being in same folder...

• How do I protect Dynamic data pages using ASP.NET Authentication?

  - by ProfK

  I have a site where most of my pages are arranged in business area folders, e.g. Activations, Outdoors, Branding. Each folder has a small web.config that protects the contents against access by people without a role for that business area. However, basic admin for most business areas is done via Dynamic Data pages. These are only basically protected by not appearing in the menu unless the user has the correct role, but they are still accessible directly via URL, because of the {table}/{Action} routing used by Dynamic Data. What can I do to protect these pages against direct access?

• Java Swing app hangs when run in normal mode but runs fine in debug mode

  - by snocorp

  I am writing a basic Java application with a Swing front-end. Basically it loads some data from a Derby database via Apache Cayenne and then displays it in a JTable. I'm doing my development in Eclipse and I don't think it's important but I'm using Maven for dependencies. Now this works fine when I run using Debug but it seems to hang the display thread when I use the Run button. I've done a thread dump and I'm not 100% certain but everything looks good. I used Java VisualVM and the threads look fine there as well. Strangely it seems to work intermittently. It's pretty consistent though and easy to reproduce. If anyone has any ideas, I'm all out of them.

• Is there a list of language only character regions for UTF-8 somewhere?

  - by Brehtt

  I'm trying to analyze some UTF-8 encoded documents in a way that recognizes different language characters. For my approach to work I need to ignore non-language characters, such as control characters, mathematical symbols etc. Just trying to dissect the basic Latin section of the UTF standard has resulted in multiple regions, with characters like the division symbol being right in the middle of a range of valid Latin characters. Is there a list somewhere that identifies these regions? Or better yet, a Regex that defines the regions or something in C# that can identify the different characters?

• Will WF 4.0 make me Obsolete

  - by codemnky

  I saw a post on Oslo about making us obsolete. I just happened to listen to the latest Deep Fried Episode with Brian Noyes. They were talking about SharePoint and Windows Workflow and how the "dream" of Windows Workflow is to let mere Business Analyst Drag and Drop their way to a functioning service. I am a newbie dotnet developer, and afraid that by the time I get to Consulting "Level" my skills would be obsolete. Should I abandon learning basic skills and just learn how to work with Frameworks and Packaged applications such as SAP, SharePoint, BizTalk. Am I wasting time trying to learn Expression Trees and Func of T's?

• Rails Multiple Table Inheritance question

  - by Tony

  I am starting to implement an MTI solution and have a basic question. I have 3 physical models - SMSNotifications, EmailNotifications, TwitterNotifications and they are subclasses of notification. At times in my code, I want to say Notifications.find(:all)so that I can get a set of results sorted by their creation time. Then I want to do things based on their subclass. What is the way to write Notifications.find(:all) and have Rails look through the subclass tables and combine the results? Right now Rails still thinks I have a physical Notifications table which goes against my MTI design. I am also considering the possibility that I should be using STI instead. I would probably have 10 empty columns per row but if getting all notifications requires a query for each type of notification, then I feel like this could be a big issue. Thanks!

• Foolproof way to check for nonzero (error) return code in windows batch file

  - by Pat

  Intro There's a lot of advice out there for dealing with return codes in batch files (using the ERROLEVEL mechanism), e.g. Get error code from within a batch file ERRORLEVEL inside IF Some of the advice is to do if errorlevel 1 goto somethingbad, while others recommend using the %ERRORLEVEL% variable and using ==, EQU, LSS, etc. There seem to be issues within IF statements and such, so then delayedexpansion is encouraged, but it seems to come with quirks of its own. Question What is a foolproof (i.e. robust, so it will work on nearly any system with nearly any return code) way to know if a bad (nonzero) code has been returned? My attempt For basic usage, the following seems to work ok to catch any nonzero return code: if not errorlevel 0 ( echo error level was nonzero )

• A realistic and usable (VS2010) MVC2 project template?

  - by pomarc

  Hello. everybody. The default MVC2 web project template which VS2010 creates when you select "ASP.NET MVC2 Web Application" is quite a nice start... but nowhere near a realistic app framework. E.G.: user accounts without such features as password recover easily customizabile (and maybe multilingual) error messages an interface to manage users, such a searcheable user list, user edit and so on which an admin can use and these are just the beginning of the usual, mandatory basic features a web site of any size may use. Searching through the online projects templates doesn't seem to help, ehiter. Are there any project template sites or else that you are aware of, that gives such features? thanks a lot!

• VB.net: Custom ' TODO: List on an Interface

  - by Shiftbit

  How do I add my own todo and comments list to appear on Interfaces? I want it to pop up like IDisposable does: Public Class Foo : Implements IDisposable Private disposedValue As Boolean = False ' To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub #Region " IDisposable Support " ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub #End Region End Class Whenever I enter my own comments and todo list they are never autogenerated like IDisposable Interface does. I would like my own Interfaces to preserve the comments so that I can share my Interfaces with in source documentation.

• Disable Eventlogging for some events using Healthmonitoring

  - by Rody van Sambeek

  I'm using basic healthmonitoring in an ASP.Net website. I'd like to prevent one event with a specific eventcode to appear in the eventlog. All other errors should be logged accordingly. I'd like to accomplish this using plain web.config settings. However I am unable to get it to work. Besides that, using IIS 5 on Windows XP does not write any events to the event log. I can't seem to find out what's wrong, on Windows 2003 it correctly logs the errors. Does anybody have an idea?

• Mobile Specific Site Development. Where to start?

  - by Andy

  I'm beginning the process of learning the ins and outs of developing sites for mobile web browsers. Are there any good resources/communities online that discuss mobile specific site development issues? My initial understanding is that to cover different phones you need to build one site that is enabled for browsers with the webkit engine (iphone, android, etc.) and another more basic site for other older browsers, is this assumption correct? Also what does developing for webkit mean exactly? How is it different than just using javascript/css/html? Is it the same except that you limit yourself to webkit specific functions and css? I looked on the webkit site, but it didn't explain it in those terms. Are there any other snafus I need to watch out for when developing for mobile browsers?

• HTML form requirements specification

  - by Peder

  I am building a framework that will validate forms both client-side (javascript) and server-side based on a form requirements specification written in json. The purpose is to get rid of logically equivalent code on the server and client to make the code more maintainable, faster to write, and less buggy. The specification format may look something like: { '&lt;field_name>' : ['&lt;validation_function>', 'req', ['&lt;requirement>', &lt;param>], ...], ... } ( the requirement list is ordered so that the user can get most basic error messages first, the 'req' requirement must come first if it exists and means that the field is required) e.g.) { 'name' : ['string', 'req', ['min',6], ['max',150], ['match', /^[\sa-z0-9ÅÄÖåäö&]$/i], ['not_match', /^tmp_/]], 'email' : ['email', 'req'], 'email_confirm' : ['same_as', 'email'], 'password' : ['string', 'req', ['min', 6], ['max', 64], ['match', /^[a-z0-9\!@#\$%^&*_+.]$/i] ], } Does anyone know of a similar technology? I think the Rails validation framework solves the problem on the wrong level because I have found that forms often operate on more than one model.

• JQuery.ajax success function returns empty

  - by viatropos

  I have a very basic AJAX function in JQuery: $.ajax({ url: "http://www.google.com", dataType: "html", success: function(data) { alert(data); } }); But the data is always an empty string, no matter what url I go to... Why is that? I am running this locally at http://localhost:3000, and am using JQuery 1.4.2. If I make a local response, however, like this: $.ajax({ url: "http://localhost:3000/test", dataType: "html", success: function(data) { alert(data); } }); ...it returns the html page at that address. What am I missing here?

• How do I get Mathematica to thread a 2-variable function over two lists, using functional programmin

  - by Leah Wrenn Berman

  Lets say I have a function f[x_, y_], and two lists l1, l2. I'd like to evaluate f[x,y] where x runs over the list l1 and y runs over the list l2, and I'd like to do it without having to make all pairs of the form {l1[[i]],l2[[j]]}. (Motivation: I'm trying to implement some basic Haskell programs in Mathematica. In particular, I'd like to be able to code the Haskell program isMatroid::[[Int]]->Bool isMatroid b =and[or[sort(union(xs\\[x])[y]'elem'b|y<-ys]|xs<-b,ys<-b, xs<-x] I think I can do the rest of it, if I can figure out the original question, but I'd like the code to be Haskell-like. Any suggestions for implementing Haskell-like code in Mathematica would be appreciated.)

• problem adding a where clause to a T-sql LEFT OUTER JOIN query

  - by Nickson

  SELECT TOP (100) PERCENT dbo.EmployeeInfo.id, MIN(dbo.EmployeeInfo.EmpNo) AS EmpNo, SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken FROM dbo.EmployeeInfo LEFT OUTER JOIN dbo.LeaveApplications ON dbo.EmployeeInfo.id = dbo.LeaveApplications.EmployeeID WHERE (YEAR(dbo.LeaveApplications.ApplicationDate) = YEAR(GETDATE())) GROUP BY dbo.EmployeeInfo.id, dbo.EmployeeMaster.EmpNo ORDER BY DaysTaken DESC The basic functionality i want is to retrieve all records in table dbo.EmployeeInfo irrespective of whether a corresponding record exists in table dbo.LeaveApplications. If a row in EmployeeInfo has no related row in LeaveApplications, i want to return its SUM(dbo.LeaveApplications.DaysAuthorised) AS DaysTaken column as NULL or may be even put a 0. With the above query, if i remove the where condition, am able to achieve what i want, but problem is i also want to return related rows from LeaveApplication only if ApplicationDate is in the current year. Now with the where condition added, am only able to get rows from EmployeeInfo only if they have corresponding rows in LeaveApplications yet i just wanted rows all in EmployeeInfo

• How to release a simple program

  - by Zenya

  What is the best practice for releasing a simple software? Suppose I created a very small simple and useful program or a tool and would like to share it with everyone by uploading it to my web-site. Do I need a license and which one? (I read http://www.gnu.org/ and http://www.fsf.org/ but still cannot decide - there are too many of them.) Do I need to put somewhere a copyright and what is the basic principles of creating "Copyright" string? How can I make a user, who is going to download and install my program, to believe that my program doesn't contain viruses or a malicious code?

• 2d parabolic projectile

  - by ndg

  I'm looking to create a basic Javascript implementation of a projectile that follows a parabolic arc (or something close to one) to arrive at a specific point. I'm not particularly well versed when it comes to complex mathematics and have spent days reading material on the problem. Unfortunately, seeing mathematical solutions is fairly useless to me. I'm ideally looking for pseudo code (or even existing example code) to try to get my head around it. Everything I find seems to only offer partial solutions to the problem. In practical terms, I'm looking to simulate the flight of an arrow from one location (the location of the bow) to another. It strikes me there are two distinct problems here: determining the position of interception between the projectile and a (moving) target, and then calculating the trajectory of the projectile. Any help would be greatly appreciated.

• Extracting a Rails application into a plugin or engine

  - by Globalkeith

  I have a Rails 2.3 application which I would like to extract into a plugin, or engine. The application has user authentication, and basic cms capabilities supported by ancestry plugin. I want to extract the logic for the application into a plugin/engine so that I can use this code for future projects, with a different "skin" or "theme" if required. I'm not entirely sure I actually understand the difference between plugin and engine concepts, so that would be a good first point. What is the best approach, are there any good starting points, links, explanations, examples that I should follow. Also, with the release of R3 to consider, is there anything that I should be aware of for that, with regards to plugins etc. I am going to start off by watching Ryan's http://railscasts.com/episodes/149-rails-engines but obviously thats over a year old now, so one of the challenges I'm faced with is finding the most up to date and relevant information on this subject. All tips and help gratefully received.

• Using asp.net mvc model binders generically

  - by Sean Chambers

  I have a hierarchy of classes that all derive from a base type and the base type also implements an interface. What I'm wanting to do is have one controller to handle the management of the entire hierarchy (as the actions exposed via the controller is identical). That being said, I want to have the views have the type specific fields on it and the model binder to bind against a hidden field value. something like: <input type="text" name="model.DerivedTypeSpecificField" /> <input type="hidden" name="modelType" value="MyDerivedType" /> That being said, the asp.net mvc model binders seem to require the concrete type that they will be creating, because of that reason I would need to create a different controller for every derived type. Has anyone does this before or know how to manipulate the model binder to behave in this way? I could write my own model binder, but I'm not wanting anything past the basic model binding behavior of assign properties and building arrays on the target type. Thanks!

• What are best practices for securing the admin section of a website?

  - by UpTheCreek

  I'd like to know what people consider best practice for securing the Admin sections of websites, specifically from an authentication/access point of view. Of course there are obvious things, such as using SSL and logging all access, but I'm wondering just where above these basic steps people consider the bar to be set. For example: Are you just relying on the same authentication mechanism that you use for normal users? If not, what? Are you running the Admin section in the same 'application domain'? What steps do you take to make the admin section undiscovered? (or do you reject the while 'obscurity' thing)
