• Check if there are any repeated elements in a array recursively

  - by devoured elysium

  I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

• Accessing E4X nodes having special characters in name without breaking binding chain in flex.

  - by Jonas

  I am using E4X to bind some values from xml in flex 3. There is a problem when xml tag's (or attribute's) name has special character in it: having xml content var xml:XML = <tag> <special-name att="val" /> </tag> special-name could not be accessed using xml.special-name.@att because it is interpreted as subtraction, on the other hand using square bracket notation xml['special-name'].@att breaks binding chain. Is there an elegant way to solve this (like special language syntax) without writing custom binding setters and listeners?

• Visual Studio CLR project

  - by Vit

  Hi, so I wanted to try my first CLR project in Visual C++. So I created console project, but since every tutorial I found about CLR programming was using C#, or windows forms, I just tried writing standart c++ Hello Word app using iostream (I think code isnt needed in this case) but I though it will give me some compile error, since iostream uses precompiled functions, and CLR app compiles into MSIL. I assumed that CLR programming using C++ means just using C++ syntax, but different functions for I/O and so. So, basicly, what I want to ask is, can any native console C++ app be compiled into MSIL and run by .NET framework?

• VS2010's "Public Property <PropertyName> As <DataType> vs. Public var

  - by Velika2

  In VS2008, I used to type Public Property <PropName> As <dataType> and hit the Enter key and the IDE editor would automatically expand it out to a full blown property block. Now, from what I understand, a new feature of 2010 is that the compiler automatically "expands" the short syntax above into the same IL code that you would get with the full property GET AND SET sub methods that were are accustomed to seeing before in the editor. But functionality, how the heck is this any different than just having a Public class level variable? If the only diff is what it compiles to and if otehrwise there is no functional difference, isn't the new way less efficient than the old since it involves more code than just having a class level memory variable? Public as I thought that if you weren't going to have code behind your properties that they were essentially the same. I guess the diffrenece is that they just added the keyword "Property" but functionality, their is no diff, eh?

• Naming convention in Objective C /C , start with "_"?

  - by Tattat

  Something I see ppl define the variable like this: b2World *_world; b2Body *_body; CCSprite *_ball; instead of b2World *world; b2Body *body; CCSprite *ball; I familiar with the second one, but not the first one. So, I checked the Wikipedia about naming convention: Names beginning with double underscore or an underscore and a capital letter are reserved for implementation (compiler, standard library) and should not be used (e.g. __reserved or _Reserved). So, is that any special meaning which is start with "_"? The wiki page.

• pointer to member function question

  - by Steve

  Hello, I'm trying to replicate a template I've used before with a member function, and it isn't going very well. The basic form of the function is template<class T> T Convert( HRESULT (*Foo)(T*)) { T temp; Foo(&temp); //Throw if HRESULT is a failure return temp; } HRESULT Converter(UINT* val) { *val = 1; return S_OK; } int _tmain(int argc, _TCHAR* argv[]) { std::cout << Convert<UINT>(Converter) << std::endl; return 0; } For the life of me, I can't get this to work with a member variable. I've read up on their syntax, and I can't seem to figure out how to make it work with templates. The class would be something similar to class TestClass { HRESULT Converter(UINT* val) { *val = 1; return S_OK; } }

• How to add an self defined attribute to ldap user?

  - by Arnab Das

  Hi, I have created an attribute in LDAP using the following code. attrs.put("NUMERICOID", "1.3.6.1.4.1.42.2.27.4.2.3.1.1.9"); attrs.put("NAME", "myattribute"); attrs.put("DESC", "for JNDITutorial example only"); attrs.put("SYNTAX", "1.3.6.1.4.1.1466.115.121.1.15"); DirContext schema = context.getSchema(""); DirContext newAttr = schema.createSubcontext ("AttributeDefinition/myattribute1", attrs); The attribute is created successfully, Now I am trying to add this attribute to a user say "user1"(uid). Attributes attributeslist = context.getAttributes(ld.getUserDN(username)); attributeslist.put("myattribute1", ""); context.modifyAttributes(ld.getUserDN("test5"), DirContext.REPLACE_ATTRIBUTE, attributeslist); But it gives me object class violation error. Can anyone help me to solve this? I need to add an user defined attribut to the user using java code.

• Paypal IPN Confirmation Screen immediately after redirect without reload

  - by Email

  Hi I made a script for IPN which works great but how can i immediately notify the user? I mean paypal redirects the customer to a custom-page i can define, simultanously my ipn.php checked the status, BUT how can i immediately tell the customer on this custom-page that it was successful or not. this custom-page does somehow has to know that this is the customer-xyz which made the ipn-verified!!! payment xyz, but how? i think also this custom-page redirect should wait the 5 seconds because php does only process files/request on-loads... so after 5 seconds the ipnscript surely did complete. Sorry if this question is too newby but i dont know how to notify the customer about the (ipn-verified!!!) payment-status immediately. How do you do this? Thanks so much

• jQuery remove selected option from this

  - by odavy

  Hi all, first post here, I come in peace :) I've searched but can't quite find what I'm after. I am trying to manipulate the selected option of a select box. Can someone please explain why this works: $('#some_select_box').click(function() { $('#some_select_box option:selected').remove(); }); but this doesn't: $('#some_select_box').click(function() { $('this option:selected').remove(); }); I just want to use "this" instead of spelling out the id of the select box - can someone point me in the right direction for the correct syntax? It's driving me mad because it looks like it should be really simple. And I'm sure it is to someone, but not me, cos its the end of the day and I'm brain-fried... Any pointers much appreciated. Cheers

• Erlang bit indexing

  - by GTDev

  I am currently trying to learn erlang and what I am trying to do is to perform an operation on specific indices of an array stored in a bit array or int. If there is a 0 in a position, the index into the array at that position is not used. So envision the following: Example the array is: [1, 3, 5, 42, 23] My bit array is: 21 = 10101 in binary so I'm using indicies 1,3,5 so I'm calling a function on [1, 5, 23] my function is of the form my_function(Array, BitArray) -> SubArray = get_subarray_from_bitarray(Array, BitArray), process_subarray(SubArray). And I need help with the get_subarray_from_bitarray(). I know erlang has special syntax around bit strings (something like <<) so is there an efficient way of indexing into the bit array to get the indicies?

  - by sagivo

  i'm trying to define a way to send emails using gmail. it all works fine on localhost but when i deploy to heroku nothing happens. i guess it has something to do with GoDaddy MX records? here is what i tried: ActionMailer::Base.smtp_settings = { :address => "smtp.gmail.com", :port => 587, :domain => "gmail.com", :user_name => "my_user", :password => "my_pass", :authentication => "plain", :enable_starttls_auto => true } i can't change the GoDaddy MX records since i'm forwording some emails from there to my Gmail account. am i missing something? EDIT- it turns out the problem was with my Gmail account. all i needed to turn off the 2-step verification. Problem solved.

• Better to use constructor or method factory pattern?

  - by devoured elysium

  I have a wrapper class for the Bitmap .NET class called BitmapZone. Assuming we have a WIDTH x HEIGHT bitmap picture, this wrapper class should serve the purpose of allowing me to send to other methods/classes itself instead of the original bitmap. I can then better control what the user is or not allowed to do with the picture (and I don't have to copy the bitmap lots of times to send for each method/class). My question is: knowing that all BitmapZone's are created from a Bitmap, what do you find preferrable? Constructor syntax: something like BitmapZone bitmapZone = new BitmapZone(originalBitmap, x, y, width, height); Factory Method Pattern: BitmapZone bitmapZone = BitmapZone.From(originalBitmap, x , y, width, height); Factory Method Pattern: BitmapZone bitmapZone = BitmapZone.FromBitmap(originalBitmap, x, y, width, height); Other? Why? Thanks

• MinGW and "delcaration does not declare anything"

  - by Bob Somers

  I'm working on converting a Linux project of mine to compile on Windows using MinGW. It compiles and runs just fine on Linux, but when I attempt to compile it with MinGW it bombs out with the following error message: camera.h:11: error: declaration does not declare anything camera.h:12: error: declaration does not declare anything I'm kind of baffled why this is happening, because I'm using the same version of g++ (4.4) on both Linux and Windows (via MinGW). The contents of camera.h is absurdly simple. Here's the code. It's choking on lines 11 and 12 where float near; and float far; are defined. #include "Vector.h" #ifndef _CAMERA_H_ #define _CAMERA_H_ class Camera{ public: Vector eye; Vector lookAt; float fov; float near; float far; }; #endif Thanks for your help.

• noindex, follow on list views?

  - by Fabrizio

  On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

• Seam page navigation with includes

  - by Marc

  Hello, I'm using seam page navigation rules. and did not experience any problem with adding rules which redirect from one page to another. But since I designed my page views using those redirection simply don't happen anymore for those pages. Tried to define the rule to the view that gets included, then to the view that includes the others (which to me was making more sense) but none work. Is there anything special about page navigation in seam using included view-id ? I'm using jsf, xhtml as my page views. Thanks

• Which design pattern should I be using?

  - by Gabriel

  Here's briefly what I'm trying to do. The user supplies me with a link to a photo from one of several photo-sharing websites (such as Flickr, Zooomr, et. al). I then do some processing on the photo using their respective APIs. Right now, I'm only implementing one service, but I will most likely add more in the near future. I don't want to have a bunch of if/else or switch statements to define the logic for the different websites (but maybe that's necessary?) I'd rather just call GetImage(url) and have it get me the image from whatever service the url's domain is from. I'm confused how the GetImage function and classes should be designed. Maybe I need the strategy pattern? I'm still reading and trying to understand the various design patterns and how I could make one fit in this case. I'm doing this in C#, but this question is language-agnostic.

• Modifying NSDate to represent 1 month from today

  - by bmalicoat

  I'm adding repeating events to a Cocoa app I'm working on. I have repeat every day and week fine because I can define these mathematically (3600*24*7 = 1 week). I use the following code to modify the date: [NSDate dateWithTimeIntervalSinceNow:(3600*24*7*(weeks))] I know how many months have passed since the event was repeated but I can't figure out how to make an NSDate object that represents 1 month/3 months/6 months/9 months into the future. Ideally I want the user to say repeat monthly starting Oct. 14 and it will repeat the 14th of every month.

• What is the best solution to do Reporting on Object data for .NET ?

  - by Peter Fox

  Hi, Our projects are using objects as the data source to reports. Our business layer is returning single objects or IEnumerable. Our reports (quite complex) need to display value-type properties of the object, and its related objects. Typical case would be, from a List, display a master report with category data, then a subreport with data for each Product inside each Category, then a subreport for each Part of each Product, and so on. Reporting from the database is not an option for us. We have tried so far - Reporting Services : works but have to mess around with the XML definition of the report to define the datasource classes, very hard to work with if you use an object datasource, architecturally not too clean - Telerik Reports : quite nice (esp., nice architecture) but seems to have problems with complex reports (master/sub), does not give great paging control, rumored to have performance/crash problems (immature product). Does anyone know a good reporting solution that can be integrated in an ASP.NET application and works well with objects as datasources ?

• Not able to pass multiple override parameters using nose-testconfig 0.6 plugin in nosetests

  - by Jaikit

  Hi, I am able to override multiple config parameters using nose-testconfig plugin only if i pass the overriding parameters on commandline. e.g. nosetests -c nose.cfg -s --tc=jack.env1:asl --tc=server2.env2:abc But when I define the same thing inside nose.cfg, than only the value for last parameter is modified. e.g. tc = server2.env2:abc tc = jack.env1:asl I checked the plugin code. It looks fine to me. I am pasting the part of plugin code below: parser.add_option( "--tc", action="append", dest="overrides", default = [], help="Option:Value specific overrides.") configure: if options.overrides: self.overrides = [] overrides = tolist(options.overrides) for override in overrides: keys, val = override.split(":") if options.exact: config[keys] = val else: ns = ''.join(['["%s"]' % i for i in keys.split(".") ]) # BUG: Breaks if the config value you're overriding is not # defined in the configuration file already. TBD exec('config%s = "%s"' % (ns, val)) Let me know if any one has any clue.

• Managing multiple WCF endpoints for the same service

  - by Jacob

  I am building an single application that uses WCF to call out to multiple external endpoints. All of the remote endpoints are identical except for the URI. I would like to treat them as a pool: add and remove endpoints through configuration and have the application understand what to do. My original plan was to define one endoint in the app.config, then iterate over my list of endpoints and update client.Endpoint.Address on the fly to point to the right place. Unfortunately, that property is read-only, rendering that plan unworkable. I'm a little bit stumped here. Any suggestions on how I might accomplish this?

• Only the last run in a for loop in Javascript works

  - by Mengfei Murphy

  Here is a for loop written by Javascript. It is trying to apply queries for websql. for (var i = 0; i < 10; i++){ db.transaction(function (tx){ tx.executeSql('INSERT INTO ProjSetsT (ProjID) VALUES (?);', [i]); }); } The attempt is obvious, I tried to add values "0, 1, 2, ... 9" into column ProjID in table ProjSetsT. It does not work. I only got the last element, i.e. "9" inserted, but not the first eight numbers. Is there any syntax mistakes?
