  • Cast element in Java For Each statement

    - by Carl Summers
    Is it possible (or even advisable) to cast the element retrieved from a for each statement in the statement itself? I do know that each element in list will be of type . I.E.: List<BaseType> list = DAO.getList(); for(<SubType> element : list){ // Cannot convert from element type <BaseType> to <SubType> ... } rather than: List <BaseType> list = DAO.getList(); for(<BaseType> el : list){ <SubType> element = (<SubType>)el; ... }

  • Why doesnt doesnt HTML input of type file not work with Ajax update panel

    - by Sean P
    I have a input of type file and when i try to do a Request.files when the input is wrapped in an update panel...it always returns an empty httpfilecollection. Why??? This is the codebehind: (At HttpContext.Current.Request.Files...its always 0 for the count.) Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim uploads As HttpFileCollection uploads = HttpContext.Current.Request.Files For i As Integer = 0 To (uploads.Count - 1) If (uploads(i).ContentLength > 0) Then Dim c As String = System.IO.Path.GetFileName(uploads(i).FileName) Try uploads(i).SaveAs("C:\UploadedUserFiles\" + c) Span1.InnerHtml = "File Uploaded Sucessfully." Catch Exp As Exception Span1.InnerHtml = "Some Error occured." End Try End If Next i End Sub This example comes from the ASP.Net website...but my application is very similar.

When I put this spec inside spec/helpers/application_helper_spec.rb everything was working without single problem. # spec/helpers/application_helper_spec.rb require 'spec_helper' describe ApplicationHelper do it do helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f| f.input :created_at, :as =>:custom_datepicker end.should =~ /something/ end end Now I'm trying to move that spec to spec/inputs/something_input_spec.rb so it will be similar name path. # spec/imputs/something_input_spec.rb require 'spec_helper' describe SomethingInput do it do helper.simple_form_for @foo,:method=>'get', :url=>helper.users_path do |f| f.input :created_at, :as =>:custom_datepicker end.should =~ /something/ end end # #ERROR: undefined local variable or method `helper' for #<RSpec::Core::ExampleGroup the thing I want to tell RSpec to threat this file as type helper spec, so I will have helper method availible with all the RSpec::Rails::HelperExampleGroup functionality ... how can I do that ??

  • NHibernate How to specify custom sql type only in production

    - by Davide Orazio Montersino
    I am saving binary files into a Sql Server 2005 Db using Fluent NHibernate. However, I am using SQLite to run my (pseudo) Unit Tests. I need to use a custom Sql type for Ms Sql, but it would throw an error on SqlLite. What strategies can I use? This is the Map file: public class BinaryFile { public BinaryFile() { m.Map(x => x.BinaryData);//.CustomSqlType("varbinary(MAX)"); m.Map(x => x.ContentType); m.Map(x => x.FileName); m.Map(x => x.FileSize); } }

  • Problems with type and ext attribute of artifact

    - by user315228
    Hi, I have following definition in ivy.xml <dependency org="southbeach" name="ego" rev="4.3.1" conf="properties->asterik" > <artifact name="ego" type="conf" ext="conf" conf="properties->asterik"/> </dependency> I have files with either extension conf or properties which i need at runtime, in ivysettings.xml, i have following: <filesystem name="privateFSa"> <artifact pattern="${localRepositoryLocation}/[artifact].[ext]" /> </filesystem> It always tries to look for ego.jar instead of ego.conf. can please somebody shed light on this? am i doing something wrong or ivy just supports tar,zip,gz, jar and not properties or conf files? I did workaround for now in ivysettings.xml <filesystem name="privateFSa"> <artifact pattern="${localRepositoryLocation}/[artifact].conf" /> </filesystem> but this doesnt looks good to hardcode conf there. Thanks, Almas

  • Looking for Team Development type Software like SVN

    - by SoLoGHoST
    I am in need of a software that is PHP-Based, or similar that can be installed on my server that doesn't offer SVN Perks. It should be somewhat similar to an SVN, however, since the server doesn't support SVN, we'll need another means of doing sort of the same thing. We have a team of Developers and need to accomplish progress in the same way that an SVN does, but without that type of server support. Is there any software that could be installed via webhosting that would be somewhat, if not exactly, similar to an SVN? Please help, Thanks :) P.S. - This is related to development AFAIK, but not exactly code-related.

  • Returning a ReadOnlyCollection from a method with an IList return type

    - by devoured elysium
    Here I have the following bit of code: private IList<IState> _states = new List<IState>(); private ReadOnlyCollection<IState> _statesViewer; public IList<IState> States { get { return _statesViewer; } } Generally it is preferable to return interfaces than the concrete classes themselves, but in this case, shouldn't I set as the return type of the States property a ReadOnlyCollection? Any user of my library will think it is possible to anything you can do with an IList if I set it as so, and that means adding elements. That is not true and I'm definitely breaking the contract exposing it as an IList. Am I right with this view or there is something else I am missing here?

  • data type mismatch when comparing dates in MS-Access

    - by jonos
    I have dates stored in an MS-Access table in the 'General Date' format. I'm trying to create a query that returns records between a specific date range (all records from March 2010) however I encounter a 'data type mismatch in critera expression' message. Here is my statement; SELECT Loan.loan_datetimeLeant, product_name, [product_artist/director], product_category, loanItem_cost FROM Loan INNER JOIN ((Product INNER JOIN Item ON Product.[product_id] = Item.[product_id]) INNER JOIN Loan_Items ON Item.[item_id] = Loan_Items.[item_id]) ON (Loan.[cust_id] = Loan_Items.[cust_id]) AND (Loan.[loan_datetimeLeant] = Loan_Items.[loan_datetimeLeant]) WHERE Loan.loan_datetimeLeant = '01/03/2010' AND Loan.loan_datetimeLeant <= '31/03/2010' ORDER BY Loan.loan_datetimeLeant ; I have tried variations on the date format (mm/dd/yyyy, dd/mm/yyyy 00:00:00)

  • navigation framework in silverlight 3 skipping constructor when usercontrol is of a derived type

    - by tarren
    Hi: I am using the NavigationFramework in Silverlight 3, and am running into issues where the constructor of the UserControl in the xaml I am loading is not being called, and I believe this is because the UserControl in the xaml I am calling is actually derived from another user control. I have stepped through the debugger with specific break points and the constructor is being ignored completey. I have MyWindowBlue which is of type uctrlBaseMyWindow. The constructor for uctrlBaseMyWindow is being called when the xaml is 'navigated to' but the constructor for MyWindowBlue is being ignored. This is not the case if I add the user control via markup directly. Anyone else have this issue? The code I am using to navigate to the MyWindowBlue is this.MyContentFrame.Navigate(new Uri("/Controls/uctrlMyWindowBlue.xaml", UriKind.Relative)); Has anyone run into this or could offer any help? Thanks

  • Internal compiler error: Could not load type NHibernate.Cfg.Configuration

    - by Simon
    I'm referencing the NHibernate dll version 2.1.2-GA, and am unable to compile under Mono 2.8.1. I've tried using NHibernate 3 instead and it compiles fine. A simple example of the code that's failing is NHibernate.Cfg.Configuration cfg = new NHibernate.Cfg.Configuration(); and the error is Error CS0584: Internal compiler error: Could not load type 'NHibernate.Cfg.Configuration' from assembly 'NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4'. (CS0584) As mentioned it compiles with no problems using NHibernate 3, does anyone have any ideas how to get it working with NHiberate 2.1.2?

  • Why is Window.open()'s return type void ?

    - by Salvin Francis
    Doing something like this is perfectly permissible in javascript: var newWindow = window.open(...) However, this does not work in the senario of GWT (I am using 1.5 I dont know about later versions), Window window = Window.open("", "", ""); Throws me a compile time error that the open is a method with a return type as void. Why should it be void ? What if i want to close my popup from the main Window ? how do I get its handle ? I will have to resort to native javascript no doubt but i was just curious so as to why this is so...

  • bytea type & nulls, Postgres

    - by Thanatos
    I'm using a bytea type in PostgreSQL, which, to my understanding, contains just a series of bytes. However, I can't get it to play well with nulls. For example: =# select length(E'aa\x00aa'::bytea); length -------- 2 (1 row) I was expecting 5. Also: =# select md5(E'aa\x00aa'::bytea); md5 ---------------------------------- 4124bc0a9335c27f086f24ba207a4912 (1 row) That's the MD5 of "aa", not "aa\x00aa". Clearly, I'm Doing It Wrong, but I don't know what I'm doing wrong. I'm also on an older version of Postgres (8.1.11) for reasons outside of my control. (I'll see if this behaves the same on the latest Postgres as soon as I get home...)

  • mysqli and field types

    - by Mikk
    Hi, I'd like to know if there is a simple way to fetch data from mysql tables with "correct" data types? What i mean, if field type is for example INT or SMALLINT is it possible to pass those types directly to PHP as integers? I did some searching and found mysqli_fetch_fields, but for SMALLIT type is 2, for INT 3 and so on. It could be done that way, but it looks rather clumsy workaround. Is there any better way? I'm using PHP and mysqli. Thank you.

  • how can i use switch statement on type-safe enum pattern

    - by Fer
    I found a goodlooking example about implementation enums in a different way. That is called type-safe enum pattern i think. I started using it but i realized that i can not use it in a switch statement. My implementation looks like the following: public sealed class MyState { private readonly string m_Name; private readonly int m_Value; public static readonly MyState PASSED= new MyState(1, "OK"); public static readonly MyState FAILED= new MyState(2, "ERROR"); private MyState(int value, string name) { m_Name = name; m_Value = value; } public override string ToString() { return m_Name; } public int GetIntValue() { return m_Value; } } What can i add to my class in order to be able to use this pattern in switch statements in C#? Thanks.

  • net.sf.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type

    - by lot
    Hi! What might be reasons for running in the quoted exception upon a HQL select, when there is actually no NULL value in the respective field in the database? I've checked the database multiple times. I've manually submitted the query statement produced by hibernate (extracted from debug). Null values for the respective field are actually never returned. However, the corresponding row in the database is in fact nullable. Does hibernate care about the data base definition? I know, I could simple change the filed to a wrapper type, but we have a number of such fields in a legacy application and this only occurs upon a single query. I'm just wondering about the actual reason for getting this exception only with a single property. Any hints would be greatly appreciated.

  • Require Integer Value not Memory Address whilst avoiding Invalid receiver type compiler warning

    - by Dave Anderson
    I have the following code; int days = [[SettingsUtils daysToRetainHistory] intValue]; [retainHistory setText:[NSString stringWithFormat:@"Days to retain History: %d", days]]; [daysToRetainHistory setValue:days animated:NO]; where [SettingsUtils daysToRetainHistory] is as follows; + (int) daysToRetainHistory { return (int)[[NSUserDefaults standardUserDefaults] objectForKey:@"CaseBaseDaysToRetainHistory"]; } I get the compiler warning Invalid receiver type 'int' because I call intValue on an int but unless I do this I can't seem to get the integer value out and always end up with the memory address i.e. 98765432 instead of 9 which ruins the UILabel display [retainHistory] and the UISlider [daysToRetainHistory] value. How do I avoid the compiler warning and still get my integer value in the label and the necessary float value for setting the UISlider value?

  • iphone screen - type of view to use

    - by Fiona
    Hi There everyone... looking for some advice on what type of view can be used to build a screen with the following elements: 2 labels followed by 2 buttons. Then a small table view with 3 rows. Should a UIView be used or a UITableView? I've attempted using a UITableView - however I couldn't add the labels or buttons. So I've now built the view using a UIView. I added the labels and buttons and then a UITableView from the library. However I have no idea how to populate the rows in the table? Any ideas? Regards, Fiona
