  • How do I set the user's locale on a JSP

    - by ebynum
    I have a .jsp page that the user loads directly. The request it with a URL like the following: http://www.example.com/myfile.jsp?country=CA&language=fr In the JSP, I pull the URL GET parameters and attempt to set the locale using them as follows: <% String myLanguage = request.getParameter("language"); String myCountry = request.getParameter("country"); Locale myLocale = new Locale(myLanguage, myCountry); pageContext.setAttribute("myLocale", myLocale, PageContext.PAGE_SCOPE); %> <fmt:setLocale value="${myLocale}" scope="page" /> There are several places in the JSP that then display a message pulled from a localized resource bundle using <bean:message bundle="ts" key="..." /> from Struts. On the first request for this page (after changing the language in the URL), it is returned in US English (the default Locale), and then subsequent refreshes will return the properly localized content.

  • Too many JavaScript and CSS files on my ASP.NET MVC 2 Master Page?

    - by Zack Peterson
    I'm using an EditorTemplate DateTime.ascx in my ASP.NET MVC 2 project. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime>" %> <%: Html.TextBox(String.Empty, Model.ToString("M/dd/yyyy h:mm tt")) %> <script type="text/javascript"> $(function () { $('#<%: ViewData.TemplateInfo.GetFullHtmlFieldId(String.Empty) %>').AnyTime_picker({ format: "%c/%d/%Y %l:%i %p" }); }); </script> This uses the Any+Time™ JavaScript library for jQuery by Andrew M. Andrews III. I've added those library files (anytimec.js and anytimec.css) to the <head> section of my master page. Rather than include these JavaScript and Cascading Style Sheet files on every page of my web site, how can I instead include the .js and .css files only on pages that need them--pages that edit a DateTime type value?

  • difference fixed width strings and zero-terminated strings

    - by robUK
    Hello, gcc 4.4.4 c89 I got into a recent discussion about "fixed width strings" and "zero terminated strings". When I think about this. They seem to be the same thing. A string with a terminating null. i.e. char *name = "Joe bloggs"; Is a fixed width string that cannot be changed. And also has a terminating null. Also in the discussion I was told that strncpy should never been used on 'zero terminated strings'. Many thanks for any susgestions,

  • Linq-to-Sql query advice please

    - by Mantorok
    Hi all Just wondering if this is a good approach, I need to search for items containing all of the specified keywords in a space-delimted string, is this the right approach this? var result = (from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid orderby row.EventName select new {row, time}); // Split the keyword(s) to limit results with all of those words in. foreach(var keyword in request.Title.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)) { var val = keyword; result = result.Where(row=>row.row.EventName.Contains(val)); } var end = result.Select(row=>new EventDetails { Title = row.row.EventName, Description = TrimDescription(row.row.Description), StartDate = row.time.StartDate, EndDate = row.time.EndDate, Url = string.Format(ConfigurationManager.AppSettings["EventUrl"], row.row.guid) }); response.Total = end.Count(); response.Result = end.ToArray(); Is there a slick Linq-way of doing all of this in one query? Thanks

  • Attributed strings in UITableViewCells without WebView?

    - by arnekolja
    Hello, does anyone know if there's a way in with 3.0+ to display attributed strings within a UITableViewCell without using a UIWebView for that? I need to display a string with linked, tappable substrings as the typical detailTextLabel. I wouldn't mind exchanging this UILabel against another type of view, but I think a UIWebView could be just too slow when rendering a table with hundrets of cells. Or does someone have opposite experiences here? So my question is: what's the best way to achieve mixed strings in a very large table without a great performance hit? I searched for this almost a whole day now, but I can only find old posts mentioning that there's no attributed string on the iPhone (outdated, as this was pre-3.0) and/or saying that they use a UIWebView for that. But really, I don't think this would perform very well on large tables, would it? Many, many thanks in advance Arne

  • Unicode data from NSData to NSString

    - by Jeff
    So if I have NSData from an HTTP request, then I do something like this: NSString *test = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; This will result in null if the data contains weird unicode data (title is from reddit): {"title":"click..¦¦me..and..then¦¦________ ¦¦check¦¦_.your...¦¦.__...¦¦____ ¦¦....¦¦¦¦¦¦¦¦¦¦¦¦¦¦....¦¦____ ¦¦¦¦¦¦....¦¦¦¦¦¦....¦¦¦¦¦¦____ ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦____ ....¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦______ ........¦¦..._recently....¦¦________ ....¦¦....viewed....links....¦¦_____"}, How would I convert the data to a string? Ideally, it would best if the string wasn't null so I could parse it as JSON, but even a lossy conversion is fine with me in these cases. I'm not familiar with unicode (naive American I am), so any enlightenment about that would be a nice bonus :)

  • Type problem when including tuple

    - by Person
    I'm using Visual Studio 2008 with Feature Pack 1. I have a typedef like this typedef std::tr1::tuple<std::string, std::string, int> tileInfo with a function like this const tileInfo& GetTile( int x, int y ) const. In the implementation file the function has the exact same signature (with the added class name qualifier) and I am getting a redefinition: different type modifiers error. It seems to be looking for an int& instead of a tileInfo& When I mouse over the type of the function in the header, i.e. tileInfo& it brings up a little bar saying static const int tileInfo. I think this may be the problem, but I'm not sure what to do. Any help is appreciated, thanks.

  • How to get Firefox to not continue to show "Transferring data from..." in browser status bar after a

    - by Edward Tanguay
    The following silverlight demo loads and displays a text file from a server. However, in Firefox (but not Explorer or Chrome) after you click the button and the text displays, the status bar continues to show "Transferring data from test.development..." which erroneously gives the user the belief that something is still loading. I've noticed that if you click on another Firefox tab and then back on the original one, the message goes away, so it seems to be just a Firefox bug that doesn't clear the status bar automatically. Is there a way to clear the status bar automatically in Firefox? or a way to explicitly tell it that the async loading is finished so it can clear the status bar itself?

  • HTML form requirements specification

    - by Peder
    I am building a framework that will validate forms both client-side (javascript) and server-side based on a form requirements specification written in json. The purpose is to get rid of logically equivalent code on the server and client to make the code more maintainable, faster to write, and less buggy. The specification format may look something like: { '&lt;field_name>' : ['&lt;validation_function>', 'req', ['&lt;requirement>', &lt;param>], ...], ... } ( the requirement list is ordered so that the user can get most basic error messages first, the 'req' requirement must come first if it exists and means that the field is required) e.g.) { 'name' : ['string', 'req', ['min',6], ['max',150], ['match', /^[\sa-z0-9ÅÄÖåäö&]$/i], ['not_match', /^tmp_/]], 'email' : ['email', 'req'], 'email_confirm' : ['same_as', 'email'], 'password' : ['string', 'req', ['min', 6], ['max', 64], ['match', /^[a-z0-9\!@#\$%^&*_+.]$/i] ], } Does anyone know of a similar technology? I think the Rails validation framework solves the problem on the wrong level because I have found that forms often operate on more than one model.

  • Automapping to EntityKeys in Entity Framework

    - by CodeGrue
    Does anyone have a technique to automap (using Automapper) references to child entities. So say I have a ViewModel: class AddressModel { int Id; string Street; StateModel State; } class StateModel { int Id; string Name; } And I pass this into a repository to map to equivalent entities in Entity Framework. When Automapping, I want it to automap AddressModel.State.ID to the EntityKey of AddressEntity.StateReference. So hand crafted code would look like this: addressEntity.Id = AddressModel.Id; addressEntity.Street = AddressModel.Street addressEntity.StateReference.EntityKey = new EntityKey("MyDB.States", "Id", AddressModel.State.Id); Obviously, when automapper tries to assign an Address.State.Id to the equivalent in EF, an exception is thrown.

  • XSD: xs:sequence & xs:choice combination for xs:extension elements?

    - by bguiz
    Hi, My question is about defining an XML schema that will validate the following sample XML: <rules> <other>...</other> <bool>...</bool> <other>...</other> <string>...</string> <other>...</other> </rules> The order of the child nodes does not matter. The cardinality of the child nodes is 0..unbounded. All the child elements of the rules node have a common base type, rule, like so: <xs:complexType name="booleanRule"> <xs:complexContent> <xs:extension base="rule"> ... </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="stringFilterRule"> <xs:complexContent> <xs:extension base="filterRule"> ... </xs:extension> </xs:complexContent> </xs:complexType> My current attempt at defining the schema for the rules node is below. However, Can I nest xs:choice within xs:sequence? If, where do I specify the maxOccurs="unbounded" attribute? Is there a better way to do this, such as an xs:sequence which specifies only the base type of its child elements? <xs:element name="rules"> <xs:complexType> <xs:sequence> <xs:choice> <xs:element name="bool" type="booleanRule" /> <xs:element name="string" type="stringRule" /> <xs:element name="other" type="someOtherRule" /> </xs:choice> </xs:sequence> </xs:complexType> </xs:element>

  • best practice for passing many arguments to method ?

    - by Tony
    Occasionally , we have to write methods that receive many many arguments , for example : public void doSomething(Object objA , Object objectB ,Date date1 ,Date date2 ,String str1 ,String str2 ) { } When I encounter this kind of problem , I often encapsulate arguments into a map. Map<Object,Object> params = new HashMap<Object,Object>(); params.put("objA",ObjA) ; ...... public void doSomething(Map<Object,Object> params) { // extracting params Object objA = (Object)params.get("objA"); ...... } This is not a good practice , encapsulate params into a map is totally a waste of efficiency. The good thing is , the clean signature , easy to add other params with fewest modification . what's the best practice for this kind of problem ?

  • Use of text() function when using xPath in dom4j

    - by jlawless
    I have inherited an application that parses xml using dom4j and xPath: The xml being parsed is similar to the following: <cache> <content> <transaction> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77145</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77147</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_PROCESSING</widget> <widget name="TRANS_DETAIL_ID">77152</widget> <widget name="GRD_ERRORS" /> </page> </transaction> </content> </cache> Individual Nodes are being searched using the following: String xPathToGridErrorNode = "//cache/content/transaction/page/widget[@name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']/../widget[@name='TRANS_DETAIL_ID'][text()='77147']/../widget[@name='GRD_ERRORS_TEMP']"; org.dom4j.Element root = null; SAXReader reader = new SAXReader(); Document document = reader.read(new BufferedInputStream(new ByteArrayInputStream(xmlToParse.getBytes()))); root = document.getRootElement(); Node gridNode = root.selectSingleNode(xPathToGridErrorNode); where xmlToParse is a String of xml similar to the excerpt provided above. The code is trying to obtain the GRD_ERROR node for the page with the PAGE_ID and TRANS_DETAIL_ID provided in the xPath. I am seeing an intermittent (~1-2%) failure (returned node is null) of this selectSingleNode request even though the requested node is in the xml being searched. I know there are some gotchas associated with using text()= in xPath and was wondering if there was a better way to format the xPath string for this type of search.

  • 'Why' and 'Where' Generics is actually used?

    - by NLV
    Hi all I know that generics are used to achieve type safety and i frequently read that they are largely used in custom collections. But why actually do we need to have it generic? For example, Why cant i use string[] instead of List<string> Lets consider i declare generic class and it has a property X T x; If i provide a method for the class which does x = x + 1; what does it mean actually? I dono what T is actually going to be and i dono what x = x + 1 going to perform actually? If i'm not able to do my own manipulations in my methods how the generics are going to be help me anyway? I've already studied lot of bookish answers. It would be much appreciated if any one can provide some clear insights in this. Regards NLV

  • How to write in an file in MSIL code

I would like to modify MSIL code (so just with ILDASM/ILASM tools) of my assembly in order to log something in a file. I have tried to add this at the end of the authentification method of my assembly : IL_0034: ldstr "C:\\path_to_my_website\\log.txt" IL_0039: newobj instance void [mscorlib]System.IO.StreamWriter::.ctor(string) IL_003e: stloc.1 IL_003f: ldloc.1 IL_0040: ldstr "test" IL_0045: callvirt instance void [mscorlib]System.IO.TextWriter::Write(string) IL_004a: nop IL_004b: ldloc.1 IL_004c: callvirt instance void [mscorlib]System.IO.TextWriter::Close() IL_0051: nop ILASM does not find any error, and the CLR does not throw any exception at runtime, but the file is not created or modified ! :( Any idea ?

  • Passing a 'var' into another method

    - by Danny
    Hi, I am probably totally missing the point here but.... How can I pass a 'var' into another method? (I am using linq to load XML into an Enumerable list of objects). I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used. XNamespace xmlns = ScehmaName; var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName) select new Object1 { Field1 = (string)e.Element(xmlns + "field1"), Field2 = (string)e.Element(xmlns + "field2") }; var result2 = Enumerable.Distinct(result); This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues: foreach (var w in result2) { if (w.CheckIT()) { //do something } } What I would love is the final step to be in a method in the base class, and I can pass the 'var' varible into it from each child class.

  • Extract a regular expression match in R version 2.10

    - by tovare
    Hi, I'm trying to extract a number from a string. And do something like this [0-9]+ on this string "aaaa12xxxx" and get "12". I thought it would be something like: > grep("[0-9]+","aaa12xxx", value=TRUE) [1] "aaa12xxx" And then I figured... > sub("[0-9]+", "\\1", "aaa12xxxx") [1] "aaa12xxx" But I got some form of response doing: > sub("[0-9]+", "ARGH!", "aaa12xxxx") [1] "aaaARGH!xxx" There's a small detail I'm missing Please advice :-) I'm using R version 2.10.1 (2009-12-14) Thanks ! Comments on the solution The best solution is to ignore the standard functions and install Hadley Wickham's stringr package to get something that actually makes sense. Kudos to Marek for figuring out how the standard library worked.

  • UITableView with Core Data and fetchedResultsController - don't want to call it at start up

    - by zebulon
    Hi all, I started with the Navigation-based application. I have a UITableView that shows the content fetched from CoreData - using the - (NSFetchedResultsController *)fetchedResultsController from the template. The thing is that I don't want to fill the TableView with the results at the start-up, instead I want to fill the TableView with the results from a search. In my app I have an UITextField, where the user can type a string. And from that string, using predicate, I want to fill the UITableView with the results. In other words, at start-up, the UITableView should be empty and later filled with the search-results. Does anyone have an idea on how to accomplish this? Thanks in advance! EDIT: Solved it by moving out if (![fetchedResultsController_ performFetch:&error]) { and calling it later. I feel a bit stupid ;)
