• asp.net and Visual studio root directory question

  - by Mark Kadlec

  I am seeing something very odd and thought I would ask the Stackoverflow community if they knew the answer. I have an asp.net project that runs fine in one environment, but couldn't figure out what happened to the styles in another environment. In the first environment (Windows 2008 Server), the following link worked fine: <link href="/Styles/09/style.css" rel="stylesheet" type="text/css" /> but in the other environment (it's a Windows 7), I had to change it to work: <link href="../Styles/09/style.css" rel="stylesheet" type="text/css" /> Notice that the directories seemed to shift ahead one directory in the Win7, what's going on? It's like the "running" directory seems now be the \bin directory instead of the home! Which environment is configured correctly? How do I determine execution directory level? My concern going forward is pushing to a prod environment and guessing which configuration is correct. Any insight would be appreciated!

• How to interact between GameCanvas and LCDUI elements on J2ME?

  - by Santiago

  The thing is I writing a J2ME program that fisrt of all show a "menu" using graphics interface (GameCanvas) and when the user select one item, I need to setCurrent that item (ex. a List), but when return from the List (it could be because the user push a Command "Menu" Item) I need to show the menu again. The real problem when the menu show again, the keyPressed() listener of gamecanvas object stop working. Basically I have: A Midlet object with: GameCanvas object instance A List object instance I don't understand how that works, I didn't find tutorial that share low and high graphics-level APIs on one Midlet.

• Apache thrift, struct contain itself

  - by mamu

  I am looking into thrift for serialization of data. But Document says cyclic structs - Structs can only contain structs that have been declared before it. A struct also cannot contain itself One of our requirement is Struct A List of Child items Items(Items are Struct A ) So reading requirement i can't have Struct within itself at any level? can i have it in cyclic model as i have it above. Struct is not member of Struct directly but it has some other member and it contains struct. Their document is not so well descriptive. Is it possible in Thrift? Does protobuf supports it?

• Windows Phone 7 and C++/CLI

  - by Fabio Ceconello

  Microsoft recently released tools and documentation for its new Phone 7 platform, which to the dismay of those who have a big C++ codebase (like me) doesn't support native development anymore. Although I've found speculation about this decision being reversed, I doubt it. So I was thinking how viable would be to make this codebase available to Phone 7 by adapting it to compile under C++/CLI. Of course the user interface parts couldn't be ported, but I'm not sure about the rest. Anyone had a similar experience? I'm not talking about code that does heavy low-level stuff - but there's a quite frequent use of templates and smart pointers.

• .NET Forms Abstraction for WPF, Silverlight, Winforms, WebForms, etc...

  - by tyndall

  Anyone know of a project(s) that seek to abstract form definitions on level higher than WPF, Silverlight, Winforms, WebForms, etc... I'm working on a project where we are fixing up 16 somewhat simple WebForms. But we may convert (and probably will convert to WPF or Silverlight 3 to 4 months from now. I'd rather define these forms once and be done with it. I'm willing to write a small DSL to help define forms, subforms, validation, links, and popups. I'm only looking to solve this for 80% or 90% of the forms. Four are very complicated and I'm willing to hand code these. I guess I'm looking for something like what XUL had hoped to be.

• Memcachedb Versus MongoDB Versus CouchDB in terms of file based caching solution?

  - by Scott Faisal

  We need a caching solution that essentially caches data (text files) anywhere from 3 days up to a week based on user preferences and criteria. In this case memory based caching does not make sense to us. We were referred to MemcacheDB however I also thought of some NO SQL solutions. Our current application uses RDMS (MYSQL) and I guess it makes sense to use MemcacheDB however NOSQL does appeal as it is something more on the horizon. However we have not deployed a production level application under NOSQL and the beta stuff does not settle well with management/investors. Any how what are your thoughts and how would you address it? Thank You

• Pass Types as arguments to a function in Haskell?

  - by Charles Peng

  The following two functions are extremely similar. They read from a [String] n elements, either [Int] or [Float]. How can I factor the common code out? I don't know of any mechanism in Haskell that supports passing types as arguments. readInts n stream = foldl next ([], stream) [1..n] where next (lst, x:xs) _ = (lst ++ [v], xs) where v = read x :: Int readFloats n stream = foldl next ([], stream) [1..n] where next (lst, x:xs) _ = (lst ++ [v], xs) where v = read x :: Float I am at a beginner level of Haskell, so any comments on my code are welcome.

• sqlalchemy: what is the difference between declaring the cascade within the foreign key vs relation?

  - by steve

  what is the difference between declaring the cascade within a foreign key vs relations? class Contact(Base): __tablename__ = 'contacts' id = Column(Integer, primary_key=True) addresses = relation("Address", backref="contact") class Address(Base): __tablename__ = 'addresses' id = Column(Integer, primary_key=True) contact_id = Column(Integer, ForeignKey('contact.id', onupdate="CASCADE", ondelete="CASCADE"))) vs class Contact(Base): __tablename__ = 'contacts' id = Column(Integer, primary_key=True) addresses = relation("Address", backref="contact", cascade="all, delete-orphan") class Address(Base): __tablename__ = 'addresses' id = Column(Integer, primary_key=True) contact_id = Column(Integer, ForeignKey('contact.id')) with the foreign key declaration, it seems like the cascade is enforced at the database level. how does the relations approach work? thanks!

• XML fragment with multiple roots: suppressing VS error

  - by Laurent

  In Visual Studio, I have an XML file (with .xml extension) which contains an XML fragment that I use in my program: <tag1> data ... </tag1> <tag2> data ... </tag2> Visual Studio shows me an error in the error list: "XML document cannot contain multiple root level elements". But this is not a complete document, just a fragment that will be reused. I want to keep my 2 roots in my fragment. How can I get rid of the error message? Thanks

• MVC & Design patterns in C++

  - by theunanonim

  I have an assignment (university level) in C++ The application that was done so far: - MVC agenda - the views are command-line - Agenda contains a list of contacts - a contact may be a friend or an acquiantance - Agenda may contain also a Company that is a contact and may contain other contacts (sorry the code is already too big as I tried to keep the MVC aspect of the application, and I can't post it here or request your time to study it..) To do: - implement factory method pattern - implement observer pattern - implement strategy pattern - implement visitor pattern The evaluation will depend on the number of added patterns and places they have been added. Am I an idiot or this is the stupidies possible assignement ? If not, please help me with some basic tips.. which one where ? Best Regards. P.S. Sorry for my English

• How do I make the footer stretch vertically downward align to footer.

  - by text

  I am new to web design using tableless and I'm having problem positioning some elements on my page.. Here's the sample html: http://christianruado.comuf.com/sample.html As you can see from the screen shots I want my right div to be vertically stretched down to the same level of my footer and position my bottom element to the lowest part of the right container. #right { float:right; width: 19%; background:#FF3300; margin-left:2px; height: 100%; } #right .bottom { bottom:0; display:block; background-color:#FFCCFF; height:30px; }

• Lazy evaluation with ostream C++ operators

  - by SavinG

  I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

• Rails: getting logic to run at end of request, regardless of filter chain aborts?

  - by JSW

  Is there a reliable mechanism discussed in rails documentation for calling a function at the end of the request, regardless of filter chain aborts? It's not after filters, because after filters don't get called if any prior filter redirected or rendered. For context, I'm trying to put some structured profiling/reporting information into the app log at the end of every request. This information is collected throughought the request lifetime via instance variables wrapped in custom controller accessors, and dumped at the end in a JSON blob for use by a post-processing script. My end goal is to generate reports about my application's logical query distribution (things that depend on controller logic, not just request URIs and parameters), performance profile (time spent in specific DB queries or blocked on webservices), failure rates (including invalid incoming requests that get rejected by before_filter validation rules), and a slew of other things that cannot really be parsed from the basic information in the application and apache logs. At a higher level, is there a different "rails way" that solves my app profiling goal?

• Problem with acceding in DOM with jQuery

  - by Tristan

  Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

• Why is 'using' improving C# performances

  - by Wernight

  It seems that in most cases the C# compiler could call Dispose() automatically. Like most cases of the using pattern look like: public void SomeMethod() { ... using (var foo = new Foo()) { ... } // Foo isn't use after here (obviously). ... } Since foo isn't used (that's a very simple detection) and since its not provided as argument to another method (that's a supposition that applies to many use cases and can be extended), the compiler could automatically call Dispose() without the developper requiring to do it. This means that in most cases the using is pretty useless if the compiler does some smart job. IDisposable seem low level enough to me to be taken in account by a compiler. Now why isn't this done? Wouldn't that improve the performances (if the developpers are... dirty).

• Should HTTP POST be discouraged?

  - by Tomas Sedovic

  Quoting from the CouchDB documentation: It is recommended that you avoid POST when possible, because proxies and other network intermediaries will occasionally resend POST requests, which can result in duplicate document creation. To my understanding, this should not be happening on the protocol level (a confused user armed with a doubleclick is a completely different story). What is the best course of action, then? Should we really try to avoid POST requests and replace them by PUT? I don't like that as they convey a different meaning. Should we anticipate this and protect the requests by unique IDs where we want to avoid accidental duplication? I don't like that either: it complicates the code and prevents situations where multiple identical posts may be desired.

• Oracle Triggers Query..

  - by AGeek

  Lets consider a Table STUD and a ROW-Level TRIGGER is implemented over INSERT query.. My scenario goes like this, whenever a row is inserted, a trigger is fired and it should access some script file which is placed in the hard disk, and ultimately should print the result. So, is this thing is possible? and if yes, then this thing should exist in dynamic form, i.e. if we change the content of script file, then the oracle should reflect those changes as well. I have tried doing this for java using External Procedures, but doesn't feel that much satisfied with the result that i wanted. Kindly give your point-of-view for this kind of scenario and ways that this can be implemented.

• Space requirements of a merge-sort

  - by Arkaitz Jimenez

  I'm trying to understand the space requirements for a Mergesort, O(n). I see that time requirements are basically, amount of levels(logn) * merge(n) so that makes (n log n). Now, we are still allocating n per level, in 2 different arrays, left and right. I do understand that the key here is that when the recursive functions return the space gets deallocated, but I'm not seeing it too obvious. Besides, all the info I find, just states space required is O(n) but don't explain it. Any hint? function merge_sort(m) if length(m) = 1 return m var list left, right, result var integer middle = length(m) / 2 for each x in m up to middle add x to left for each x in m after middle add x to right left = merge_sort(left) right = merge_sort(right) result = merge(left, right) return result

• How do I manage permissions on multiple items in SharePoint 2007?

  - by mk

  I'm relatively new to SharePoint and am trying to put a bunch of Word files (that were on our network file server) into SharePoint. We have set up a document library that, by default, gives everyone access to everything. This is the desired top-level permission set because most items will work well this way. The problem is that I have a bunch of documents I want to add and apply some specific permissions to. I can do this, but...please tell me there is some way I can do this for multiple documents at the same time. Attempting to do this one-by-one is a pain and I'm hoping for a better solution here. Thanks very much in advance.

• C++ - Access array (in main) from methods outside main

  - by John Smith

  I have an array in my main class that holds objects that I need to print out for a menu listing. The array is declared and initialized in main. I need to, however, access the same array in a sub-menu function. If I copy the code (for loop that prints out the values) to the sub-menu, nothing is printed (presumably because it can't access the original array and has made a new, blank one). Is there any way (without making the array a global variable) that I can access the array in this sub-menu? Both the main and the sub-menu function are in the same file and the sub-menu is called from main. Maybe to put it more simply, can I use scope resolution to bring me up one 'level' in scope?

• How to run SpecFlow tests in Visual Studio 2010?

  - by testerboy

  Trying to get SpecFlow running with a fresh VS2010 Professional install. Created a new console application and added references to NUnit and SpecFlow. Created a SpecFlow feature. The .feature with the default template code is created. Now I try to run this test, but I don't understand how. When I right-click the project (at the top-level), there is no "Run test(s)" option in the mouse drop down menu. Didn't the SpecFlow install correctly, am I missing some references or some other tool I need to install?
