  • grails date from params in controller

    - by nils petersohn
    y is it so hard to extract the date from the view via the params in a grails controller? i don't want to extract the date by hand like this: instance.dateX = parseDate(params["dateX_value"])//parseDate is from my helper class i just want to use instance.properties = params you know :) in the model the type is java.util.Date and in the params is all the information (dateX_month, dateX_day, ...) i searched on the net and found nothing on this :( i hoped that grails 1.3.0 could help but still the same thing. i can't and will not belief that extracting the date by hand is nessesary!

    - by TiNS
    Hi All, I am using JFreeChart to generate images. I am trying to create barchart like below. I am able to create it successfully without data table. I tried to get more information from the jfreechar forums and found this post. According to the post , its not supported by JfreeChart. Is it still not supported by jfreechart API ? If yes, can I use any other charting (open source) tool to generate chart with data table ? Thanks

  • How to efficiently handle Where and OrderBy clauses

    - by Goran
    My business layer passes all the required information to UI layer. From what I have read, in general, best practice is to send fetched data to UI layer, and to avoid passing queries like ObjectQuery. My problem with this approach is next: If I am to make a flexible business layer, then I should allow UI to sort the data anyway it requires. Fetching sorted data from database, and then resorting them in UI is kind of bad practice for me, so the only way is to somehow So what are my options? Is there a way to make it like this: public void OrderByMethod(params ...) { .... } so I can call it like this: OrderByMethod(MyEntity.Property1, MyEntity.Property2 descending....); Thanks, Goran

  • Youtube python: get thumbnail

    - by dkgirl
    Is there a simple way to get the default thumbnail from a youtube entry object gdata.youtube.YouTubeVideoEntry? I tried entry.media.thumbnail, but that gives me four thumbnail objects. Can I always trust that there are four? Can I know which is the default thumbnail that would also appears on the youtube search page? And how would I get that one? Or do I have to alter one of the other ones? When I know the video_id I use: http://i4.ytimg.com/vi/{{video_id}}/default.jpg so, it would also be helpful to get the video_id. Do I really have to parse one of the url's to get at the video_id ? It seems strange that they don't provide this information directly.

  • Wiki for requirements engineering

    - by Shanon
    Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

  • How should I implement items that are normalized in the Database, in Object Oriented Design?

    - by Jonas
    How should I implement items that are normalized in the Database, in Object Oriented classes? In the database I have a big table of items and a smaller of groups. Each item belong to one group. This is how my database design look like: +----------------------------------------+ | Inventory | +----+------+-------+----------+---------+ | Id | Name | Price | Quantity | GroupId | +----+------+-------+----------+---------+ | 43 | Box | 34.00 | 456 | 4 | | 56 | Ball | 56.50 | 3 | 6 | | 66 | Tin | 23.00 | 14 | 4 | +----+------+-------+----------+---------+ Totally 3000 lines +----------------------+ | Groups | +---------+------+-----+ | GroupId | Name | VAT | +---------+------+-----+ | 4 | Mini | 0.2 | | 6 | Big | 0.3 | +---------+------+-----+ Totally 10 lines I will use the OOP classes in a GUI, where the user can edit Items and Groups in the inventory. It should also be easy to do calculations with a bunch of items. The group information like VAT are needed for the calculations. I will write an Item class, but do I need a Group class? and if I need it, should I keep them in a global location or how do I access it when I need it for Item-calculations? Is there any design pattern for this case?

  • Determining a location's side of the road position with MapKit

    - by idStar
    Is there a way to use MapKit in iOS7 to not only get geocoding for an address, but determine what side of the road it is on? I'm not trying to build a full function navigation app, but similar to navigation apps that tell you things like "Your destination is in 100 feet on the right", I'd like to be able to obtain this information. Does MapKit give one a way to do this? Do I need to adopt routing privileges to access such, or is this just not available in the SDK period? If not available in the iOS7 SDK, knowing what options exist as services, would be a helpful pointer.

  • How to find item selected from customContextMenuRequested() on QTreeView item?

    - by vinaym
    I have implemented contextual menus in QTreeView items with the following code MyDerivedQTreeView->setModel(MyDerivedQAbstractItemModel); MyDerivedQTreeView->setContextMenuPolicy(Qt::CustomContextMenu); connect(MyDerivedQTreeView, SIGNAL(customContextMenuRequested(const QPoint &)), MyDerivedQAbstractItemModel(), SLOT(contextualMenu(const QPoint &))); void MyDerivedQAbstractItemModel::contextualMenu(const QPoint& point) { QMenu *menu = new QMenu; menu->addAction(QString("Test Item"), this, SLOT(test_slot())); menu->exec(MyDerivedQTreeView->mapToGlobal(point)); } MyDerivedQAbstractItemModel::contextualMenu() gets called and I can see the contextual menu. Problem is contextual menu should be visible only if user right-clicks on an item and it should be customized as per the item selected. How do I get whether/which item is selected from QPoint information? I am on Qt 4.5.3.

  • Version control of Mathematica notebooks

    - by Etaoin
    Mathematica notebooks are, of course, plaintext files -- it seems reasonable to expect that they should play nice with a version-control system (git in my case, although I doubt the specific system matters). But the fact is that any .nb file is full of cache information, timestamps, and other assorted metadata. Scads of it. Which means that limited version control is possible -- commits and rollbacks work fine. Merging, though, is a disaster. Mathematica won't open a file with merge markers in it, and a text editor is no way to go through a .nb file. Has anyone had any luck putting a notebook under version control? How?

  • iphone: accessing the preferences localization file from code

    - by phonecoddy
    I was just facing the following problem and couldn't find a solution for it. Hopefully someone could help. The app I am working on has some preferences, which are using a localization file. Now I want to use labels in my app, which display the exact names, which are used in the localization file for the preferences. But I couldn't find a way to access the information which is stored in Settings.bundle - en.lproj - localizationfile.strings. to make this clear: If you open your preferences for your app, the display shows the localized string of the title and the value of the setting. I need to access the localized string of the title of each preference from my code. Does any know how to do this?

  • amazon design doubt

    - by praveen
    I was looking at the amazon website and was wondering how one of the feature would have been implemented. The feature : what customers buy after viewing a particular item. If i were to develop such a feature i would probably generate a session id for each user session and store the session id-page id combination in a log file. and if a book is bought set a separate flag for the session id-page id. A separate program can then be run on the log file periodically, to identify the groups that were bought together/viewed together and that information can be stored in a persistent file. This is ofcourse a simple solution without taking into consideration the distributed nature of the servers - but would this suffice or can you help me identify a better design.

  • .NET OutOfMemoryException on XMLSerializer.Serialize

    - by Micah
    I have a web site that is throwing OutOfMemoryExceptions on whenever it gets to the following spot in my code: XmlSerializer xs = new XmlSerializer(t, xoverrides); Seeing how this only happens when it is on the web server, i don't have a ton of information on why this is happening. I know that the objects that it is serializing aren't anything too serious-- definitely less than a MB each. Have you had this before? Feel like helping me diagnose the issue? Any help is appreciated. Thanks!

  • Need an alternative to two left joins.

    - by Scarface
    Hey guys quick question, I always use left join, but when I left join twice I always get funny results, usually duplicates. I am currently working on a query that Left Joins twice to retrieve the necessary information needed but I was wondering if it were possible to build another select statement in so then I do not need two left joins or two queries or if there were a better way. For example, if I could select the topic.creator in table.topic first AS something, then I could select that variable in users and left join table.scrusersonline. Thanks in advance for any advice. SELECT * FROM scrusersonline LEFT JOIN users ON users.id = scrusersonline.id LEFT JOIN topic ON users.username = topic.creator WHERE scrusersonline.topic_id = '$topic_id' The whole point of this query is to check if the topic.creator is online by retrieving his name from table.topic and matching his id in table.users, then checking if he is in table.scrusersonline. It produces duplicate entries unfortunately and is thus inaccurate in my mind.

  • How to query data from a password protected https website using C# .NET

    - by Addie
    I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp. I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query. System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv");

  • Drupal: I cannot connect to the database.. please help

    - by Patrick
    hi, I've hard time to make Drupal work on IIS Microsoft server. I've succesfully run Joomla on the same server so I'm pretty sure the following information are correct: host: localhost user: user pass: pass databaseName = servername_databasename I've set the following line in settings.php file: $db_url = 'mysql://user:password@localhost/servername_databasename'; but what I get is this: If you are the maintainer of this site, please check your database settings in the settings.php file and ensure that your hosting provider's database server is running. For more help, see the handbook, or contact your hosting provider. I don't get any other error message such as: database doesn't exist, user/pass wrong.. just this. The database is running, I can access with phpmyadmin. I've tried both "mysql" and "mysqli". The host is a private server (IIS Microsoft), the database is Mysql The database and website files upload have also been succesfull.. so I dunno what to do to fix this issue. thanks

  • Jpa subclass mapping

    - by Roy Chan
    I am making a POS like system. I wonder how to map subclass using JPA (this is for my DAO). Product class has product details and OrderProduct class has information about the Product and details about the order. @Entity @Table(name="products") public class Product implements Serializable{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO public int getId(){ return id;} /** Other get/set methods */ } @Entity @Table(name="order_products") public class OrderProduct extends Product{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO) public int getId(){ return id;} /** Other get/set methods */ } I got complain about duplicate @Id. But OrderProduct class really need another id than the product one. How should I map this? DB is something like this Table products id int name varchar(32) Table order_product id int quantity int productid int fk referencing product table Would @IdClass or @AttributeOverride help?

  • LINQ to SQL or Entities, at this point?

    - by orlon
    I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

  • Text code decoding

    - by Diana Villafane
    Hello. I am an English/Spanish Spanish/English translator. I have been given a job where I have to translate Spanish text messages sent from cell phones. Some of them are in code. I assume each set of figures represents a letter. Is there any website where I can find information on how to decipher the code? For instance, the first message says: ‘0x69 ox61 0x6e 0x70 0x72 0x2e 0x6e 0x65 0x74 0x2f 0x3f 0x64 0x34 0x39 0x31 0x66 0x30 0x37 0x38 0x35 0x35 0x32 0x39 0x62 0x36 0x31 0x31 0x00 Thank you for any help you provide.

  • Vendor neutral SQL

    - by Sparafusile
    I'm currently working on a project for a web application that may be installed on several different servers with various software configurations. I want to make my application as flexible as possible by allowing the user to have various SQL servers installed. The problem is the SQL syntax used by any two server vendors does not match up. For a simple example, here is the same SELECT statement for MS SQL and MySQL: MS SQL - SELECT TOP 1 * FROM MyTable ORDER BY DateCreated DESC MySQL - SELECT * FROM MyTable ORDER BY DateCreated DESC LIMIT 1 Are there any standard way to abstract the statement creation for various vendors? Any online resources or books discussing this problem? Any hints or smart-alec remarks that I'd find useful? Further information: I'm writing my we application in vanilla ASP running on a Windows server. Thanks, Spara

  • Possible to access gdata api when using Java App Engine?

    - by PCBEEF
    I have a dilemma where I want to create an application that manipulates google contacts information. The problem comes down to the fact that Python only supports version 1.0 of the api whilst Java supports 3.0. I also want it to be web-based so I'm having a look at google app engine, but it seems that only the python version of app engine supports the import of gdata apis whilst java does not. So its either web based and version 1.0 of the api or non-web based and version 3.0 of the api. I actually need version 3.0 to get access to the extra fields provided by google contacts. So my question is, is there a way to get access to the gdata api under Google App Engine using Java? If not is there an ETA on when version 3.0 of the gdata api will be released for python? Cheers.

  • Adding objects to LDAP via CGI

    - by musashiXXX
    I have a web form that collects information and submits it to a cgi that attempts to insert the data into LDAP. The problem is that I'm trying to use a variable with ::ldap::add and it's just not working. Here's the code: if {[string length env(QUERY_STRING)] != 0} { set handle [::ldap::connect localhost] set dn "cn=admin,dc=mycompany,dc=com" set pw "myPassword" ::ldap::bind $handle $dn $pw set dn "cn=[ncgi::value givenName] [ncgi::value sn],ou=people,dc=mycompany,dc=com" set formValues [ puts "cn {{[ncgi::value givenName] [ncgi::value sn]}}" puts "displayName [ncgi::value givenName] [ncgi::value sn]" foreach {key value} [ncgi::nvlist] { if {[string length $value] != 0} { puts "$key $value" } } puts "objectClass top" puts "objectClass person" puts "objectClass organizationalPerson" puts "objectClass inetOrgPerson" ] ::ldap::add $handle $dn { $formValues } ldap::unbind $handle } However, if I replace $formValues with the actual entries that I want to insert into LDAP, they get added just fine. I'm new to TCL so I wouldn't be surprised if there were some glaring errors in this snippet. Thanks in advance!

  • Printable Version of Google Visualizations DataTable

    - by maleki
    I have a custom routing application that takes information for a route from google maps. It then creates a Google Visualizations DataTable to hold all the steps in the route. My current problem is that in order to reduce overflow for very large routes, I have enabled paging in the options of the DataTable. This leads to a not so printer friendly version because only the portion of the data that is shown in the table will be printed. The other portions of the table are loaded dynamically by the API when you click prev and next. Is there a not so hard way to get the DataTable to be printer friendly when it comes time without sacrificing the ability to have paging enabled?

  • What to store at application Settings, numeric / string representations or objects?

    - by SoMoS
    Hello, I've been thinking for a while on what to store at the Project Settings, objects or numeric/string representations of those objects to set a rule and avoid thinking on this at the future so I want to take the best approach. On one side storing object representations grants you that what is stored is valid and saves you from doing conversions each time you access them. You only need objects with the attribute. At the other side storing the numeric/string representation of an object eases the editing of the setting because at the end the user will be entering numeric or string information. What do you do with this issue?

    int * ref () { int tmp = 100; return &tmp; } int main () { int * a = ref(); cout << *a << endl; } I know the function ref () is allocated stack space. It will get destroyed as soon as the function exits. So the complier will give warning information. But my question is why the returning result is still correct.

It seems really simple, but i don't know where to start. I couldn't find an relevant examples. thanks for your help!
