  • SQL query problem

    - by Brisonela
    Hi, I'm new to StackOverflow, and new to SQL Server, I'd like you to help me with some troublesome query. This is my database structure(It's half spanish, hope doesn't matter) Database My problem is that I don't now how to make a query that states which team is local and which is visitor(using table TMatch, knowing that the stadium belongs to only one team) This is as far as I can get Select P.NroMatch, (select * from fnTeam (P.TeamA)) as TeamA,(select * from fnTeam (P.TeamB)) as TeamB, (select * from fnEstadium (P.CodEstadium)) as Estadium, (cast(P.GolesTeamA as varchar)) + '-' + (cast(P.GolesTeamA as varchar)) as Score, P.Fecha from TMatch P Using this functions: If object_id ('fnTeam','fn')is not null drop function fnTeam go create function fnTeam(@CodTeam varchar(5)) returns table return(Select Name from TTeam where CodTeam = @CodTeam) go select * from fnTeam ('Eq001') go ----**** If object_id ('fnEstadium','fn')is not null drop function fnEstadium go create function fnEstadium(@CodEstadium varchar(5)) returns table return(Select Name from TEstadium where CodEstadium = @CodEstadium) go I hope I'd explained myself well, and I thank you help in advance

    - by user2898828
    I am trying to get my code to create the new constructor objects which I require to create a mobile phone object.

  • EntityFramework: using association or add property manualy

    - by dritterweg
    I'm starting to use Entity Framework. Let's say I have to Entity from my tables in DB. Here is the table schema Profiles ProfileId FirstName LastName Hobbies Id HobbyName OwnerId So one profile can have many hobbies. My Entity Framework: ProfileEntity ProfileId FirstName LastName Hobbies (collection of HobbyEntity) note: this created by the Association tool HobbyEntity Id HobbyName Owner (type of ProfileEntity) note: this created by the Association tool, for me this property is not important my question: should I use the "Association" tool to make the relationship between the two entities, which in result create a property of each entity (in ProfileEntity will create a HobbyEntity and vica versa) or should I not use the association and only add a scalar property manually such as List<HobbyEntity> in my ProfileEntity and OwnerId in HobbyEntity.

  • using Cookie-free Domains for Components

    - by JPro
    I was looking at the post here which says When the browser makes a request for a static image and sends cookies together with the request, the server doesn't have any use for those cookies. So they only create network traffic for no good reason. Although I tend not to use cookies at all, my doubt is I used to think that the server creates the cookies to store the session varialbles etc and sends to the client. But this statement says the reverse of that. I don't quiet understand what is the need for the browser to create and send cookies with the request, to me it doesn't make any sense?. Can anyone please correct me? Thanks/.

  • How can I refer to a binding converter in another namespace in Silverlight XAML?

    - by Mike Pateras
    Since you apparently can't create a Silverlight DataTemplate in C#, I'm trying to create one in XAML. I have a converter that I need to refer to, that I have defined in C# in another namespace. I've tried doing this: <UserControl.Resources> <DataTemplate x:Key="PriceTemplate"> <TextBlock Text="{Binding Price, Converter={Converters:PriceConverter}}" /> </DataTemplate> </UserControl.Resources> Where Converters is an xmlns that points to the correct namespace. However, I get a compilation error that says: Type 'Converters:PriceConverter' is used like a markup extension but does not derive from MarkupExtension. I tried adding System.Windows.Markup.MarkupExtension as a parent to my converter, but it apparently doesn't exist in Silverlight. How can I refer to my converter in XAML, without having to rewrite it in XAML?

  • Using Forms authentication with remote auth system?

    - by chobo
    I am working on a website that uses a remote websites database to check for authentication (they are both share some database tables, but are separate website...) Right now I check the username and password against the remote websites account / member table, if there is a match I create a session. Questions: Is this secure? On authenticated pages I just check if a session of a specific type exists.Is it possible for someone to create an empty session or something that could bypass this? Is it possible to use Forms authentication with this setup? Right now if a user is authenticated I just get an object back with the username, email and id.

  • Read Velocity Tokens/Tag from .vm file

    - by user1801660
    I have an application where in I am trying to create a velocity template repository which will help me centralise all my email templates and will allow me to create a communication hub. All templates will be called at runtime and populates with data via services. My problem is that I need to provide users with optional and compulsory params list when they define the template inputs for the velocity template. Is there a way to read the tokens/tags from the velocity template file and extract them?? Like I want a list of tokens $name.address.streetName to be available to me from .vm file. I do not want to go for Regex . I do not have to cache or reuse them , its just going to be a one time read and store the default,compulsory & optional params in the database. I am following these patterns : http://kickjava.com/src/org/apache/velocity/test/view/TemplateNodeView.java.htm How to use String as Velocity Template? Please advice.

  • e-commerce clothing site in .NET from the scratch or site copy ? suggestions please

    - by pointlesspolitics
    Hi all, I am thinking to create an e-commerce site for a clothing business. I have bit of a development knowledge in c# .net, html, css and other web technologies. Could you please advise on these questions ? Is it a good idea to create a site from the scratch ? I have a running example of such a site, however it is bit old. So can I start with old site and change the html and code behind ? Some people argue that it is better to use MVC for ecommerce site. Any good reasons ? BTW I don't know MVC, but can learn if I have to use it. It is decided to use .NET but if you have any ideas of better technologies, please let me know. Any ideas and issues related to payment system also welcome. Any answer will be appreciated. Thanks Rgds,

  • Command Not working in separate thread in J2me.

    - by RishiPatel
    I am creating a bluetooth application. I created a simple midlet with a exit command and i create a thread for finding the service and discovering the device. While doing so it displays a animated screen on which i added the parent commandListener for exit command. After successful connection both user is represented with greetings(Current screen calls the parent Display method setCurrent for displaying itself). This screen also have CommandListener set to the parent. Now i want to add few more commands. I Implemented the CommandLIstener Interface in this class, added few commands but the commands are not working. I dont whats wen wrong. I am giving u Code snippets to fully describle my issue : - package name Imports here public class MyMidlet extends MIDlet implements CommandListener { public CommandListener theListener; public Display theDisplay; public Command exitCommand; public MyMidlet() { // Retrieve the display for this MIDlet //Create the initial screen } public void startApp() throws MIDletStateChangeException { } public void pauseApp() { } public void destroyApp(boolean unconditional) { } public void commandAction(Command c, Displayable d) { // Determine if the exit command was selected if (c == exitCommand) { //End application here notifyDestroyed(); } else { //Start the new thread here } } } Now here is the code for the class which is invoked by the above midlet in a separate thread; package here; imports here public class MyService implements Runnable, CommandListener { private MyMidlet parent; private StreamConnection conn; private OutputStream output; private InputStream input; public Command sendCommand; private TextField messageToSend Form form; public BChatService(boolean isServer, BChatMidlet parent) { //some stuff here this.parent = parent; } public void run() { //functino for showing animation here try { input = conn.openInputStream(); output = conn.openOutputStream(); } catch (IOException e) { displayError("IO Error", "An error occurred while opening " + "the input and output streams" + "(IOException: " + e.getMessage() + ")"); try { conn.close(); } catch (Exception ex) { } return; } // Create the Form here when service is discoverd and greets the users Command sendCommand = new Command("Send", Command.ITEM, 2); exitCommand = new Command("Exit", Command.EXIT, 1); form.addCommand(exitCommand); form.addCommand(sendCommand); parent.theDisplay.setCurrent(form); form.setCommandListener(this); public void commandAction(Command c, Displayable d) { if (c == exitCommand) { // End the game parent.destroyApp(true); parent.notifyDestroyed(); } if(c == sendCommand) { form.append("SOme text here"); } } } When i select the Send command, the string doesnt append in form neither exit command works. What can be the possible cause for it?? I need to implement this functionality...Is there any other way to achieve this??

  • Entity Framework 4 Hiding Underlying Resolver Tables when model is generated from database

    - by grrrrrrrrrrrrr
    When creating an entity framework model from scratch it is possible to specify a Many to Many relationship in the model. e.g Entity1 * ----- * Entity2 When a database is then generated from this, a resolver table is then created automatically between the two entities, this is hidden in the code model, allowing direct access to each of the entities via properties. e.g. Entity1 ----* ResolverEntity *----- Entity2 My question is, when a model is generated from an existing database, which contains resolver tables, is it possible to create the same effect so the resolver tables do not appear in the generated object model? When I have attempted this, the entity framework appears to create entities in the model for the resolver tables with no obvious way of hiding them in the object model. Thanks.

  • What is this Hash-like/Tree-like Construct Called?

    - by viatropos
    I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context. Here's how I use it: Config.get("root.parent.child_b") #=> "value" Here's what the class might look like: class Construct def get(path) # split path by "." # search tree for nodes end def set(key, value) # split path by "." # create tree node if necessary # set tree value end def tree { :root => { :parent => { :child_a => "value", :child_b => "another value" }, :another_parent => { :something => { :nesting => "goes on and on" } } } } end end Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.

  • Alternatives to sign() in sqlite for custom order by

    - by Pentium10
    I have a string column which contains some numeric fields, but a lot are 0, empty string or null. The rest are numbers having different range, all positive. I tried to create a custom order by. The order would be done by two fields. First I would like to order the fields that have this number 0 and then sort by name. So something this would work: select * from table order by sign(referenceid) desc, name asc; But Sqlite lacks the sign() -1/0/1 function, and I am on Android and I can't create user defined functions. What other options I have to get this sort done.

  • Launching a Facebook page from an iPhone app via QR code

    - by user1655186
    I'm trying to create a QR code that launches a Facebook page from the app, rather than the browser on both Android and iOS. Creating the code with fb://page/<page id>, works perfectly on an Android. This was also supposed to work with iOS's Facebook app, but I think since Facebook updated their app recently from a HTML5 version to a fully native iOS app, that functionality has stopped working. It indeed opens the Facebook app, but it does not go to the page. Has anyone else seen this happen since the app was updated a few weeks ago? And what string would I have to use to create a working QR Code for iOS's Facebook app?

  • Access to bytes array of a Bitmap

    - by Deulis
    1- In Windows CE, I have a Bitmap object in C#. 2- I have a C function in an extern dll that expects as parameters the pointer to a bytes array that represents an image in RGB565 format, width and height. This function will draw on this array of bytes. So I need to pass the byte array pointer of the Bitmap object, but I can find a practical way to get this pointer. One way is convert this Bitmap into a bytes array using a memory stream or something else, but it will create a new bytes array, so I will keep in memory both object, the Bitmap and the bytes array, but I don’t want it because the few available memory, that’s why I need to access to the bytes array of the bitmap object, not create a new bytes array. Anyone can help me?

  • Object relationships

    - by Hammerstein
    This stems from a recent couple of posts I've made on events and memory management in general. I'm making a new question as I don't think the software I'm using has anything to do with the overall problem and I'm trying to understand a little more about how to properly manage things. This is ASP.NET. I've been trying to understand the needs for Dispose/Finalize over the past few days and believe that I've got to a stage where I'm pretty happy with when I should/shouldn't implement the Dispose/Finalize. 'If I have members that implement IDisposable, put explicit calls to their dispose in my dispose method' seems to be my understanding. So, now I'm thinking maybe my understanding of object lifetimes and what holds on to what is just wrong! Rather than come up with some sample code that I think will illustrate my point, I'm going to describe as best I can actual code and see if someone can talk me through it. So, I have a repository class, in it I have a DataContext that I create when the repository is created. I implement IDisposable, and when my calling object is done, I call Dispose on my repository and explicitly call DataContext.Dispose( ). Now, one of the methods of this class creates and returns a list of objects that's handed back to my front end. Front End - Controller - Repository - Controller - Front End. (Using Redgate Memory Profiler, I take a snapshot of my software when the page is first loaded). My front end creates a controller object on page load and then makes a request to the repository sending back a list of items. When the page is finished loading, I call Dispose on the controller which in turn calls dispose on the context. In my mind, that should mean that my connection is closed and that I have no instances of my controller class. If I then refresh the page, it jumps to two 'Live' instances of the controller class. If I look at the object retention graph, the objects I created in my call to the list are being held onto ultimately by what looks like Linq. The controller/repository aside, if I create a list of objects somewhere, or I create an object and return it somewhere, am I safe to just assume that .NET will eventually come and clean things up for me or is there a best practice? The 'Live' instances suggest to me that these are still in memory and active objects, the fact that RMP apparently forces GC doesn't mean anything?

  • Using Wordpress as a CMS to a site AND blog (two completely different layouts for each). Duplicate i

    - by Somebody still uses you MS-DOS
    I'm going to create a website using Wordpress static pages feature. It's going to have a menu for all the created pages. A blog is going to be created as well. This blog has a completely different layout/menu from the main site, but within the same domain: "http://www.domain.com" is the website url, and "http://www.domain.com/blog/" is the blog url. I was thinking of installing two different Wordpress instances: /var/www/public_html/ and /var/www/public_html/blog/. Although it's a simple solution, users are going to be duplicated: if you change password in one system, you need to change in the other. So, I would like to know from you which other approaches are possible: create a "dynamic" theme (call a theme when in root domain, another whern /blog - dont even know if this is possible), or for example a plugin to syncronize users from both instances? Does Wordpress MU solve this problem for me? Thanks!

  • Cannot running next process when a variable save no value

    - by bruine
    First, I wanna compare between 2 tables tb_wrapper and tb_summary to get the data in the tb_wrapper that doesn't exist in the tb_summary then save in $link. If I don't get the same data, I want to print the result $link. When I don't get the not same data, I want it to go to another process. Here's the code : $q2 = mysql_query(" SELECT a.doc_url FROM tb_wrapper a LEFT JOIN tb_summary b ON a.doc_name = b.doc_summ WHERE b.doc_summ IS NULL"); while ($row = mysql_fetch_array($q2)){ $link = $row['doc_url']; if (!$link){ include 'next_process.php'; } else { print_r($link); } } it doesn't work. When I don't get the not same data or $link not save a value. table : CREATE TABLE tb1 (`id` int, `doc_name` varchar(100), `doc_url` varchar(50)) } CREATE TABLE tb2 (`id` int, `doc_summ` varchar(100)) }

  • How best to automatically deal with multiple site_ruby locations?

    - by cclark
    Is there a way to automatically append to $: variable in ruby to account for additional site_ruby locations? Ruby is installed in /usr/local/ and using gem_install will properly install the new ruby files in to /usr/local/lib/ruby/site_ruby. However there are some RPMs for ruby bindings to tools like shadow which we'd like to install and they install to /usr/lib/ruby/site_ruby (no local). Is there a standard way to tell ruby that this directory should also be included by default? I know scripts could dynamically update $: or they could be called with -I but it seems like this is something that should be handled in the install. Has anyone else found a clean way around this kind of problem? thanks, chuck

I tried not to create table, but use MEMORY TABLE and update it using following SQL query insert into tops (uid) select uid from users order by exp desc; but got the following MySQL error Deadlock found when trying to get lock; try restarting transaction because there are too many queries until SQL select is being executed. How to solve this problem? P.S. CREATE TABLE tops as SELECT work almost fine except high server load... up to load average: 50 if tops are non-memory table. My table users has near 4.5 millions of rows. Thanks for any advices.

  • C++ allocate objects on heap of base class with protected constructors via inheritance

    - by KRao
    I have a class with protected constructor: class B { protected: B(){}; }; Now I derive from it and define two static functions and I manage to actually create objects of the class B, but not on the heap: class A : public B { public: static B createOnStack() {return B();} //static B* createOnHeap() {return new B;} //Compile time Error on VS2010 }; B b = A::createOnStack(); //This works on VS2010! The question is: 1) Is VS2010 wrong in allowing the first case? 2) Is it possible to create objects of B without modifying B in any way (no friendship and no extra functions). I am asking, because it is possible to make something similar when dealing with instances of B and its member functions, see: http://accu.org/index.php/journals/296 Thank you in advance for any suggestion! Kind regards

  • Best way to reuse a Runnable

    - by Gandalf
    I have a class that implements Runnable and am currently using an Executor as my thread pool to run tasks (indexing documents into Lucene). executor.execute(new LuceneDocIndexer(doc, writer)); My issue is that my Runnable class creates many Lucene Field objects and I would rather reuse them then create new ones every call. What's the best way to reuse these objects (Field objects are not thread safe so I cannot simple make them static) - should I create my own ThreadFactory? I notice that after a while the program starts to degrade drastically and the only thing I can think of is it's GC overhead. I am currently trying to profile the project to be sure this is even an issue - but for now lets just assume it is.

  • Error 1005 when adding a foreign key constraint on mysql table

    - by luc
    Hello, I have a problem when upgrading a django and mysql app with south. I've tried to make a sql-based upgrade with the code generated by the django sqlall command and I have a similar problem. Here is the sql code: CREATE TABLE `programmations_basissupport` ( `id` integer AUTO_INCREMENT NOT NULL PRIMARY KEY, `value` numeric(6, 0) NOT NULL ) ALTER TABLE `programmations_concert` ADD `basis_support_id` integer AFTER program_status_id; ALTER TABLE `programmations_concert` ADD CONSTRAINT `basis_support_id_refs_id_1e4ed8d7` FOREIGN KEY (`basis_support_id`) REFERENCES `programmations_basissupport` (`id`); An error is raised when adding the FK constraint: ERROR 1005 (HY000): Can't create table 'apidev_mnl.#sql-106e_632b00a' (errno: 150) Does anybody have an idea? Update: DEFAULT values where missing but even if I add the default='' in the django model, the creation of foreign keys fails. Thanks for your help
