• Finding out the version of Dojo

  - by Sandeep

  I'm kinda new to Dojo toolkit. There are certain issues which I would like to get enlightened (I googled but I didn't get any appropriate & satisfying answers) I have a dojo.js(Perhaps the uncompressed dojo.js downloaded) in my already running application (Developed by another software developer). How to find out which version of dojo.js he has downloaded and is being used right now? (Its not commented. I checked) a) While I'm trying to run my application in IE-8 (Opening a pop-up on click of a button), I get error which is pointing me to this line of code if(dojo.isIE&&window.location.protocol==="file:") Note: Its working fine in IE6 but the issue is with IE8 & to be even more specific the JS error is displayed only for the first time when I'm clicking the button. b) Is it true that dojo 1.3 & above is the best & stable release for IE8?

• On a Hudson master node, what are the .tmp files created in the workspace-files folder?

  - by Patrick Johnmeyer

  Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

• Detect double-tap on UISlider?

  - by Randy

  I can detect single/double-taps in specific views with: NSSet *myTouches = [event touchesForView:mySpecificView.view]; but I want to detect a double-tap on the button of a slider and can't find any reference to it. Is there a replacement for "touchesForView:" where I can enter the name of my slider? usage: I have three sliders with their default value being directly in the center of the slider. Once the position of the slider has changed, I want a quick way to individually reset each slider to its default position. I currently have each slider's containing view set to respond to a double-tap, updating each slider. It works fine, but doesn't seem natural. ie.I can't double-tap on the slider itself because the slider intercepts the taps and doesn't pass them on to the surrounding view. thanks in advance

• result set using two different views (from an if statement)

  - by mailman1979

  Hi All, I have a bit of code that works with a result set called "result" (original I know) but depending on the incoming variable I'd like to fire the specific query depending. I have the below in an if statement but that just makes the "result" recordset gets those nasty red lines and it doesn't work. I'm sure this is easy to work out. if (area == "dashboard") { IQueryable<ViewGetNavigationMainItem> result = (from m in _entities.ViewGetNavigationMainItems where m.area.Trim() == area.Trim() where m.state == "Online" where m.parentID == parentID orderby m.sequence ascending select m); } else { //Get the Content Items IQueryable<ViewGetNavigationContentItem> result = (from m in _entities.ViewGetNavigationContentItems where m.navID == navID where m.parentID == parentID orderby m.contentOrder ascending select m); } maxRecords = result.Count(); foreach (var item in result) { etc etc etc

• Configure multiple keystores in JBoss depending on requested hostname

  - by Mo

  Hello, I have my J2EE application deployed into a JBossAS. My Application has to respond to two different hostnames (https://foo.com/myApp and https://bar.com/myApp). It is the same instance of the app serving those two hostnames. But I don't know how to configure the keystores. I need different keystores for each hostname. Is there a way to tie a virtual host in JBoss' server.xml to a specific connector? Or do I have to use two different IP-addresses and create a connector for each? A solution that does not require a second IP-address would be greatly appreciated.

• conceptually different entities with a few similar properties should be stored in one table or more?

  - by Haghpanah

  Assume A and B are conceptually different entities that have a few similar properties and of course their own specific properties. In database design, should I put those two entities in one big aggregated table or two respectively designed tables. For instance, I have two types of payment; Online-payment and Manual-payment with following definition, TABLE [OnlinePayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [TrackingCode] [nvarchar](32), [ReferingCode] [nvarchar](32), [BankingAccID] [uniqueidentifier], [Status] [int], [Amount] [money], [Comments] [nvarchar](768), [CreatedAt] [datetime], [ShopingCartID] [uniqueidentifier], ) And TABLE [ManualPayments] ( [ID] [uniqueidentifier], [UserID] [uniqueidentifier], [BankingAccID] [uniqueidentifier], [BankingOrgID] [uniqueidentifier], [BranchName] [nvarchar](64), [BranchCode] [nvarchar](16), [Amount] [money], [SlipNumber] [nvarchar](64), [SlipImage] [image], [PaidAt] [datetime], [Comments] [nvarchar](768), [CreatedAt] [datetime], [IsApproved] [bit], [ApprovedByID] [uniqueidentifier], ) One of my friends told me that creating two distinct tables for such similar entities is not a well design method and they should be put in one single table for the sake of performance and ease of data manipulations. I’m now wondering what to do? What is the best practice in such a case?

• Configure Symfony for use with Memcached

  - by Rob Wilkerson

  I have 2 Symfony applications (1 using 1.2.x, another using 1.4.x and both using Propel) that need to share some specific session information. Although I have no experience with memcached, my sense--after some reading--is that it may be able to serve as an external (FAST) repository that each app could read and write to. Unfortunately, I can't find much information about how to use it with Symfony in any capacity, much less in the quasi-cache, quasi-messaging server I'm envisioning. My questions, I suppose, are: Am I mistaken in believing that memcached be used in this manner and access by multiple systems? How can I configure Symfony to access a memcached repository? Thanks.

• Ternary operators and variable reassignment in PHP

  - by TomcatExodus

  I've perused the questions on ternary operators vs. if/else structures, and while I understand that under normal circumstances there is no performance loss/gain in using ternary operators over if/else structures, I've not seen any mention of this situation. Language specific to PHP (but any language agnostic details are welcome) does the interpreter reassign values in situations like this: $foo = 'bar' $foo = strlen($foo) > 3 ? substr($foo, 0, 3) : $foo; Since this would evaluate to $foo = $foo; is this inefficient, or does the interpreter simply overlook/discard this evaluation? On a side note, what about: !defined('SECURE') ? exit : null;

• Runtime Error in asp.net site?

  - by Surya sasidhar

  hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

• How can i initialize an array without knowing it size?

  - by Sara

  I have a situation where i have to apply a criteria on an input array and reuturn another array as output which will have smaller size based upon the filtering criteria. Now problem is i do not know the size of filtered results, so i can not initialize the array with specific value. And i do not want it to be large size will null values because i am using array.length; later on. One way is to first loop the original input array and set a counter, and then make another loop with that counter length and initialize and fill this array[]. But is there anyway to do the job in just one loop?

• Custompage Module-Issue with CSS (Drupal-6.x)

  - by jc70

  I'm new to Drupal and have recently installed the custompage module. I received a lot of errors until I placed "custom.tpl.php" in the custompage module folder. I am able to navigate to the custom page from the primary links. But, the CSS I created for that specific page is not showing up. I'm thinking it's because "custom.tpl.php" is located in the module folder of Drupal Core and my CSS is in the theme folder. But I'm not sure how to fix the problem. I tried to copy the "custom.tpl.php" in my themes folder, but then I receive a lot of errors. Any help would be appreciated.

• Why does this jQuery dropdown menu display subcategory selections only for certain top-level categories?

  - by chunkymonkey

  I'm trying to implement a dropdown menu based on a jQuery plugin from Filament Group: http://jsfiddle.net/chunkymonkey/Pr8k4/ What I am having difficulty fixing is a bug where certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has equally many subcategories, shows no subcategories when expanded. I would be very grateful if anyone could help me figure out what's causing this. Thanks. UPDATE: Just noticed this problem may be Chrome-specific(??). I just tested it in IE8 and Firefox and it seems to work correctly in both.

• Can you use Win32 GUI in a browser plugin?

  - by John

  Of course it would mean you're plugin is not cross-platform but let's focus on the technical side... Is a browser plugin (like done in NPAPI) restricted in what it can do? Or do you get fairly free reign to access the PC and the render-window you're given? For instance can you create Win32/MFC controls in your browser this way? A side question - is your browser plugin conceptually akin to a .DLL, which is therefore just arbitrary compiled code implementing a specific interface for browser control/communication?

• Ajax twice + facbook login/logout

  - by Devenv

  Hi, I have a very specific problem. The site I'm developing loads the FB connect button by ajax (it loads the box that includes FBC button). And when user logs in it loads instead of it the box with FB logout link. The problem is that FB requires to call FB.init() at the end of the body (when all the FB stuff is already on the page) and you can't do it twice as the second time is ignored. So what happens is - I do FB.init() inside the login box and FBC button works perfectly, but the logout link doesn't as FB.init() doesn't work there. The only solution I came up with is to place the login and logout buttons outside of ajax boxes and show them in the right places after ajax boxes are loaded. I'm pretty much sure this will work but I don't like the solution (which looks more like hack).

• PODS + WP Theme

  - by Sharath

  So I managed to setup pods and create my custom tables. Now I want to revamp my theme so that it pulls data from the POD table. Doesn't seem to be working... This is what I did.. I have a Pod called 'project_type' with a name (string) and a code (string) field. Have also added 3 entries via the admin system. I made a copy of the default wordpress plugin and renamed it to myTheme and activated it. Inside index.php of myTheme, I removed all the default code.. and have just the POD specific code as shown below. <?php echo "Hello World"; $p = new Pod('project_type'); echo $p->getTotalRows(); ?> However, when I reload my page, only Hello World shows up? A bit new to Wordpress so kindly advice.

• Problem in packages in importing in Eclipse

  - by user384706

  Hi (I am using Galileo), I am trying to import some existing projects into Eclipse. The structures for their packages is: Project/ /src /java /a /b /c Once imported in the package explorer I see: Project src/java --a --b --c - AClass.java This is ok, since the classes e.g. AClass.java are defined in package: a.b.c But in one project the structure (once imported) becomes: Project src --java --a --b --c - AClass.java And that causes the error that AClass.java is defined to be in package a.b.c but it is actually under java.a.b.c Why is this happening? Why in this specific project java is not ignored as part of package? Thanks

• dymanic columns in mysql tables?

  - by fayer

  i want to add dynamic columns in a mysql table. but i dont know exactly how. i want to let the user add some columns (fields) in a thread. eg. let him add a integer field and a value (eg. price: 199) or a string field and a value (eg. name: teddybear). the user can add as many field/value-pairs as he wants. i thought i could create a many-to-many table: thread <- thread_field <- field thread: id, title thread_field: field_id, thread_id, value field: id, name is this a good structure? but in this way i have to set a specific column type of thread_field.value. either its an integer or a string. i want to have the possibility to have it dymanic, let the user choose. how can i do this? thanks!

• Passing values for multi-value parameter in SSRS query string

  - by Andy Xufuris

  I have two reports built using SSRS 2005. The first report is set to navigate to the second when a specific field is clicked. There is a multi-value parameter on the second report. I need to pass multiple values for this parameter in the URL query string when calling this report. Is there a way to pass multiple values for a parameter in the query string of a report? Or can you pass a parameter that will cause the Select All value to be selected?

• Is there a font that can't be recognised by an OCR?

  - by user1820564

  I am trying to write a document that can only be read by humans. The document content can't be copied. For that purpose, I am converting its pages to pictures and adding them back to a PDF file. The main issue is that any OCR program can get back the whole written text, especially that the page is going to be clear (as opposed to a scanned book) which will increase the OCR accuracy. So, is there a font that can't be recognized by an OCR. Otherwise, is there a technique that will make my document only readable by humans, yet unrecognised by an OCR? (for instance, adding a specific background, etc...) Thank you in advance.

• Covariant return types in Java enums

  - by Kelvin Chung

  As mentioned in another question on this site, something like this is not legal: public enum MyEnum { FOO { public Integer doSomething() { return (Integer) super.doSomething(); } }, BAR { public String doSomething() { return (String) super.doSomething(); } }; public Object doSomething(); } This is due to covariant return types apparently not working on enum constants (again breaking the illusion that enum constants are singleton subclasses of the enum type...) So, how about we add a bit of generics: is this legal? public enum MyEnum2 { FOO { public Class<Integer> doSomething() { return Integer.class; } }, BAR { public Class<String> doSomething() { return String.class; } }; public Class<?> doSomething(); } Here, all three return Class objects, yet the individual constants are "more specific" than the enum type as a whole...

• Scheme open source projects?

  - by Ben

  Hi I'm learning scheme and was wondering if there are any active open-source projects I might be able to get involved in? I'm nearing the end of SICP and although this has good complex examples no textbook code compares to real-world applications. eg testing code / benchmarking / revision control styles / sheer size and scope etc. Hence my curiousity at seeing a project in the wild. I tried searching google code but only found projects that are interpreters that implement RSR5/6. Perhaps there are not many projects out there and I should consider scala?! Advice or even pointers to specific projects appreciated.

• Using generics in dotnet for functions with any number of arguments?

  - by Zarigani

  I would like to have a function that can "wrap" any other function call. In this particular case, it would allow me to write some more generic transaction handling around some specific operations. I can write this for any particular number of arguments, e.g. for one argument: Public Shared Sub WrapFunc(Of T)(ByVal f As Action(Of T), ByVal arg As T) ' Test some stuff, start transaction f(arg) ' Test some stuff, end transaction End Sub ... but I was hoping to have this handle any number of arguments without having to have duplicate code for 0 args, 1 arg, 2 args, etc. Is there a way of doing this?

• What motivates people to learn a new programming language?

  - by szabgab

  There are plenty of question asking Which Programming Language Should I Learn? but I have not found an answer yet to the question what really motivates people to learn a specific new language?. There are the people who think they should learn a new language every year for educational purpose. How do they decide on the languages to be learned? Then I guess there are people who learn a new language because people around them told it is a fun language and they can build nice things with it. Of course if the current job requires it people would learn a new language but I think if the language seems to have a potential to earn money (e.g. There are plenty of jobs in Java or ObjectiveC can be used to write apps for the iPhone and make money). So why are you learning a new language or why have you learned the languages you know?

• Documented process for using facebook connect for the iPhone to upload photos

  - by Corey Floyd

  After looking I did come accross this post on the facebook forums: link They are feeding the facebook object a UIImage. That seems logical, but where is this documented? The API documentation is generalized to all platforms. Where are the iPhone specific requirements for arguments and their data types? Thanks **Update***** I still have not came across any API docs pertaining to Cocoa. I did, however, gather the information I needed by piecing together forum information, Facebook sample code, and some glue. Hopefully they'll issue something a little more concrete over the next few months.
