  • How do you localize/internationalize an MVC Controller when using a SQL based localization provider?

    - by EBarr
    Hopefully this isn't too silly of a question. In MVC there appears to be plenty of localization support in the views. Once I get to the controller, however, it becomes murky. Using meta:resourcekey="blah" is out, same with <%$ Resources:PageTitle.Text%. ASP.NET MVC - Localization Helpers -- suggested extensions for the Html helper classes like Resource(this Controller controller, string expression, params object[] args). Similarly, Localize your MVC with ease suggested a slightly different extension like Localize(this System.Web.UI.UserControl control, string resourceKey, params object[] args) None of these approaches works while in a controller. I put together the below function and I'm using the controllers full class name as my VirtualPath. But I'm new to MVC and assume there's a better way. public static string Localize (System.Type theType, string resourceKey, params object[] args) { string resource = (HttpContext.GetLocalResourceObject(theType.FullName, resourceKey) ?? string.Empty).ToString(); return mergeTokens(resource, args); } Thoughts? Comments?

  • Excel VBA Macro for Pivot Table with Dynamic Data Range

    - by John Ziebro
    CODE IS WORKING! THANKS FOR THE HELP! I am attempting to create a dynamic pivot table that will work on data that varies in the number of rows. Currently, I have 28,300 rows, but this may change daily. Example of data format as follows: Case Number Branch Driver 1342 NYC Bob 4532 PHL Jim 7391 CIN John 8251 SAN John 7211 SAN Mary 9121 CLE John 7424 CIN John Example of finished table: Driver NYC PHL CIN SAN CLE Bob 1 0 0 0 0 Jim 0 1 0 0 0 John 0 0 2 1 1 Mary 0 0 0 1 0 Code as follows: Sub CreateSummaryReportUsingPivot() ' Use a Pivot Table to create a static summary report ' with model going down the rows and regions across Dim WSD As Worksheet Dim PTCache As PivotCache Dim PT As PivotTable Dim PRange As Range Dim FinalRow As Long Dim FinalCol As Long Set WSD = Worksheets("PivotTable") 'Name active worksheet as "PivotTable" ActiveSheet.Name = "PivotTable" ' Delete any prior pivot tables For Each PT In WSD.PivotTables PT.TableRange2.Clear Next PT ' Define input area and set up a Pivot Cache FinalRow = WSD.Cells(Application.Rows.Count, 1).End(xlUp).Row FinalCol = WSD.Cells(1, Application.Columns.Count). _ End(xlToLeft).Column Set PRange = WSD.Cells(1, 1).Resize(FinalRow, FinalCol) Set PTCache = ActiveWorkbook.PivotCaches.Add(SourceType:= _ xlDatabase, SourceData:=PRange) ' Create the Pivot Table from the Pivot Cache Set PT = PTCache.CreatePivotTable(TableDestination:=WSD. _ Cells(2, FinalCol + 2), TableName:="PivotTable1") ' Turn off updating while building the table PT.ManualUpdate = True ' Set up the row fields PT.AddFields RowFields:="Driver", ColumnFields:="Branch" ' Set up the data fields With PT.PivotFields("Case Number") .Orientation = xlDataField .Function = xlCount .Position = 1 End With With PT .ColumnGrand = False .RowGrand = False .NullString = "0" End With ' Calc the pivot table PT.ManualUpdate = False PT.ManualUpdate = True End Sub

  • How do I use a custom authentication mechanism for a Java web application with Spring Security?

    - by Adam
    Hi, I'm working on a project to convert an existing Java web application to use Spring Web MVC. As a part of this I will migrate the existing log-on/log-off mechanism to use Spring Security. The idea at this stage is to replicate the existing functionality and replace only the web layer, leaving the service classes and objects in place. The required functionality is simple. Access is controlled to URLs and to access certain pages the user must log on. Authentication is performed with a simple username and password along with an extra static piece of information that comes from the login page. There is no notion of a role: once a user has logged on they have access to all of the pages. Behind the scenes, the service layer has a class with a simple authentication method: doAuthenticate(String username, String password, String info) throws ServiceException An exception is thrown if the login fails. I'd like to leave this existing service object that does the authentication intact but to "plug it into" the Spring Security mechanism. Can somebody suggest the best approach to take for this please? Naturally, I'd like to take the path of least resistance and leave the work where possible to Spring... Thanks in advance, Adam.

  • Loading a UITableView From A Nib

    - by Garry
    Hi, I keep getting a crash when loading a UITableView. I am trying to use a cell defined in a nib file. I have an IBOutlet defined in the view controller header file: UITableViewCell *jobCell; @property (nonatomic, assign) IBOutlet UITableViewCell *jobCell; This is synthesised in the implementation file. I have a UITableViewCell created in IB and set it's identifier to JobCell. Here is the cellForRowAtIndexPath method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"JobCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"JobsRootViewController" owner:self options:nil]; cell = jobCell; self.jobCell = nil; } // Get this job Job *job = [fetchedResultsController objectAtIndexPath:indexPath]; // Job title UILabel *jobTitle; jobTitle = (UILabel *)[cell viewWithTag:tagJobTitle]; jobTitle.text = job.title; // Job due date UILabel *dueDate; dueDate = (UILabel *)[cell viewWithTag:tagJobDueDate]; dueDate.text = [self.dateFormatter stringFromDate:job.dueDate]; // Notes icon UIImageView *notesImageView; notesImageView = (UIImageView *)[cell viewWithTag:tagNotesImageView]; if ([job.notes length] > 0) { // This job has a note attached to it - show the notes icon notesImageView.hidden = NO; } else { // Hide the notes icon notesImageView.hidden = YES; } // Job completed button // Return the cell return cell; } When I run the app - I get a hard crash and the console reports the following: objc[1291]: FREED(id): message style sent to freed object=0x4046400 I have hooked up all the outlets in IB correctly. What is the issue? Thanks,

  • Why this method does not use any properties of the object?

It is not clear to me because there is no reference to "this" in the code for the method "doSomething".

  • Iterative Cartesian Product in Java

    - by akappa
    Hi, I want to compute the cartesian product of an arbitrary number of nonempty sets in Java. I've wrote that iterative code... public static <T> List<Set<T>> cartesianProduct(List<Set<T>> list) { List<Iterator<T>> iterators = new ArrayList<Iterator<T>>(list.size()); List<T> elements = new ArrayList<T>(list.size()); List<Set<T>> toRet = new ArrayList<Set<T>>(); for (int i = 0; i < list.size(); i++) { iterators.add(list.get(i).iterator()); elements.add(iterators.get(i).next()); } for (int j = 1; j >= 0;) { toRet.add(Sets.newHashSet(elements)); for (j = iterators.size()-1; j >= 0 && !iterators.get(j).hasNext(); j--) { iterators.set(j, list.get(j).iterator()); elements.set(j, iterators.get(j).next()); } elements.set(Math.abs(j), iterators.get(Math.abs(j)).next()); } return toRet; } ...but I found it rather inelegant. Someone has a better, still iterative solution? A solution that uses some wonderful functional-like approach? Otherwise... suggestion about how to improve it? Errors? Thanks :)

  • ERROR_MORE_DATA ---- Reading from Registry

    - by user314749
    I am trying to create an offline registry in memory using the offreg.dll provided in the windows ddk 7 package. You can find out more information on the offreg.dll here: MSDN Currently, while attempting to read a value from an open registry hive / key I receive the following error: 234 or ERROR_MORE_DATA Here is the .h code that contains ORGetValue: DWORD ORAPI ORGetValue ( __in ORHKEY Handle, __in_opt PCWSTR lpSubKey, __in_opt PCWSTR lpValue, __out_opt PDWORD pdwType, __out_bcount_opt(*pcbData) PVOID pvData, __inout_opt PDWORD pcbData ); Here is the code that I am using to pull the data [DllImport("offreg.dll", CharSet = CharSet.Auto, EntryPoint = "ORGetValue", SetLastError = true, CallingConvention = CallingConvention.StdCall)] public static extern uint ORGetValue(IntPtr Handle, string lpSubKey, string lpValue, out uint pdwType, out string pvData, out uint pcbData); IntPtr myHive; IntPtr myKey; string myValue; uint pdwtype; uint pcbdata; uint ret3 = ORGetValue(myKey, "", "DefaultUserName", out pdwtype, out myValue, out pcbdata); The goal is to be able to read myValue as a string. I am not sure if I need to use marshaling... or a second call with an adjusted buffer.. Or really how to adjust the buffer in C#. Any help or pointers would be greatly appreciated. Thank you.

  • Toggle Blind Effect

    Is there a way to alter this script to be used as the blind effect. // Andy Langton's show/hide/mini-accordion - updated 23/11/2009 // Latest version @ http://andylangton.co.uk/jquery-show-hide // this tells jquery to run the function below once the DOM is ready $(document).ready(function() { // choose text for the show/hide link - can contain HTML (e.g. an image) var showText=''; var hideText=''; // initialise the visibility check var is_visible = false; // append show/hide links to the element directly preceding the element with a class of "toggle" $('.toggle').prev().append(' '+showText+''); // hide all of the elements with a class of 'toggle' $('.toggle').hide(); // capture clicks on the toggle links $('a.toggleLink').click(function() { // switch visibility is_visible = !is_visible; // toggle the display - uncomment the next line for a basic "accordion" style //$('.toggle').hide();$('a.toggleLink').html(showText); $(this).parent().next('.toggle').toggle('slow'); // return false so any link destination is not followed return false; }); }); FYI- Where it says: var showText=''; var hideText=''; It was originally: var showText='Show'; var hideText='Hide'; I deleted the Show/Hide Text because I am applying the link to different areas of text. I like the Blind effect, vs. this Toggle effect, and need to know how to apply it, if possible. I cannot find a basic Blind effect script that allows the use of applying the link to ANY text, vs. a button or static text. Thanks! Hope you can help! Tracy

  • C# and SQL - sub select from a table parameter

  • Factory Method Implementation

    - by cedar715
    I was going through the 'Factory method' pages in SO and had come across this link. And this comment. The example looked as a variant and thought to implement in its original way: to defer instantiation to subclasses... Here is my attempt. Does the following code implements the Factory pattern of the example specified in the link? Please validate and suggest if this has to undergo any re-factoring. public class ScheduleTypeFactoryImpl implements ScheduleTypeFactory { @Override public IScheduleItem createLinearScheduleItem() { return new LinearScheduleItem(); } @Override public IScheduleItem createVODScheduleItem() { return new VODScheduleItem(); } } public class UseScheduleTypeFactory { public enum ScheduleTypeEnum { CableOnDemandScheduleTypeID, BroadbandScheduleTypeID, LinearCableScheduleTypeID, MobileLinearScheduleTypeID } public static IScheduleItem getScheduleItem(ScheduleTypeEnum scheduleType) { IScheduleItem scheduleItem = null; ScheduleTypeFactory scheduleTypeFactory = new ScheduleTypeFactoryImpl(); switch (scheduleType) { case CableOnDemandScheduleTypeID: scheduleItem = scheduleTypeFactory.createVODScheduleItem(); break; case BroadbandScheduleTypeID: scheduleItem = scheduleTypeFactory.createVODScheduleItem(); break; case LinearCableScheduleTypeID: scheduleItem = scheduleTypeFactory.createLinearScheduleItem(); break; case MobileLinearScheduleTypeID: scheduleItem = scheduleTypeFactory.createLinearScheduleItem(); break; default: break; } return scheduleItem; } }

  • Receiving an object in a unmanaged callback function

    - by Daniel Baulig
    Eg. I have following delegate method I want to use as a callback function with unmanaged code: public delegate void Callback(IntPtr myObject); Callback callback; I register it in the following way: [DllImport("a.dll")] public static void registerCallback(IntPtr callbackFunction, IntPtr anObject); // ... this.myObject = new MyClass(); this.objectPin = GCHandle.Alloc(this.myObject, GCHandleType.Pinned); registerCallback(Marshal.GetFunctionPointerForDelegate(callback), objectPin.AddrOfPinnedObject()); Now whenever the callback function is called it will have a Pointer/Handle of an object of the MyClass class. I could use Marshal.PtrToStructure to convert this to an object of MyClass. However, what I would like to have is that the delegate definition already contains the class MyClass. eg.: public delegate void Callback(MyClass myObject); I tried this, but it will not work. I also tried the following, which did not work: public delegate void Callback([MarshalAs(UnmanagedType.IUnknown)]MyClass myObject); I suppose I would need something like "UnmarshalAs" at this point, but sadly this is not available. Any suggestions how I could get lost of that IntPtr in my callback function and get a it packed up as a regular, managed MyClass object?

  • Reusing Windows Picture and Fax Viewer process to load a new image from FileSystemWatcher

    - by Cory Larson
    So for an idea for my birthday party I'm setting up a photo booth. I've got software to remotely control the camera and all that, but I need to write a little application to monitor the folder where the pictures get saved and display them. Here's what I've got so far. The issue is that I don't want to launch a new Windows Photo Viewer process every time the FileSystemWatcher sees a new file, I just want to load the latest image into the current instance of the Windows Photo Viewer (or start a new one if one isn't running). class Program { static void Main(string[] args) { new Program().StartWatching(); } public void StartWatching() { FileSystemWatcher incoming = new FileSystemWatcher(); incoming.Path = @"G:\TempPhotos\"; incoming.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.FileName; incoming.Filter = "*.jpg"; incoming.Created += new FileSystemEventHandler(ShowImage); incoming.EnableRaisingEvents = true; Console.WriteLine("Press \'q\' to quit."); while (Console.Read() != 'q') ; } private void ShowImage(object source, FileSystemEventArgs e) { string s1 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\rundll32.exe "); string s2 = Environment.ExpandEnvironmentVariables("%windir%\\system32\\shimgvw.dll,ImageView_Fullscreen " + e.FullPath); Process.Start(s1, s2); Console.WriteLine("{0} : Image \"{0}\" at {1:t}.", e.ChangeType, e.FullPath, DateTime.Now); } } If you don't have a tried and true solution, a simple push in the right direction would be just as valuable. And FYI, this will be running on a 64-bit Windows 7 machine. Thanks!

  • What is default javac source mode (assert as identifier compilation)?

    - by waste
    According to Orcale's Java7 assert guide: source mode 1.3 (default) — the compiler accepts programs that use assert as an identifier, but issues warnings. In this mode, programs are not permitted to use the assert statement. source mode 1.4 — the compiler generates an error message if the program uses assert as an identifier. In this mode, programs are permitted to use the assert statement. I wrote such class: package mm; public class ClassTest { public static void main(String[] arg) { int assert = 1; System.out.println(assert); } } It should compile fine if Oracle's info right (1.3 is default source mode). But I got errors like this: $ javac -version javac 1.7.0_04 $ javac -d bin src/mm/* src\mm\ClassTest.java:5: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier int assert = 1; ^ (use -source 1.3 or lower to use 'assert' as an identifier) src\mm\ClassTest.java:6: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier System.out.println(assert); ^ (use -source 1.3 or lower to use 'assert' as an identifier) 2 errors I added manually -source 1.3 and it issued warnings but compiled fine. It seems that Oracle's information is wrong and 1.3 is not default source mode. Which one is it then?

    Hi folks, I'm trying to wire up a simple ASP.NET MVC2 controller class to my own LoggingService. Code compiles fine, but I get the following runtime error :- {"StructureMap Exception Code: 202 No Default Instance defined for PluginFamily System.Type, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"} what the? mscorlib ???? Here's some sample code of my wiring up .. protected void Application_Start() { MvcHandler.DisableMvcResponseHeader = true; BootstrapStructureMap(); ControllerBuilder.Current.SetControllerFactory( new StructureMapControllerFactory()); RegisterRoutes(RouteTable.Routes); } private static void BootstrapStructureMap() { ObjectFactory.Initialize(x => x.For<ILoggingService>().Use<Log4NetLoggingService>()); } and finally the controller, simplified for this question ... public class SearchController : Controller { private readonly ILoggingService _log { get; set; } public SearchController(ILoggingService loggingService) : base(loggingService) { // Error checking removed for brevity. _log = loggingService; _log.Tag = "SearchController"; } ... } and the structuremap factory (main method), also way simplified for this question... protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { IController result = null; if (controllerType != null) { try { result = ObjectFactory.GetInstance(controllerType) as Controller; } catch (Exception exception) { if (exception is StructureMapException) { Debug.WriteLine(ObjectFactory.WhatDoIHave()); } } } } hmm. I just don't get it. StructureMap version 2.6.1.0 ASP.NET MVC 2. Any ideas?

  • UICollectionViewCell imageView

    - by Flink
    Code works fine until I changed UIViewController with tableView to UICollectionViewController. Now all cells shows same image, sometimes it flipping to nil. However textLabels are OK. - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"TourGridCell"; TourGridCell *cell = (TourGridCell *)[collectionView dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath]; Guide *guideRecord = [self.fetchedResultsController objectAtIndexPath:indexPath]; cell.titleLabel.text = [guideRecord.name uppercaseString]; cell.titleLabel.backgroundColor = [UIColor clearColor]; if ([guideRecord.sights count] > 0) { if ([[guideRecord.sights objectAtIndex:0]valueForKey:@"thumbnail"]) { cell.imageView.image = [UIImage drawImage:[[guideRecord.sights objectAtIndex:0]valueForKey:@"thumbnail"] inImage:[UIImage imageNamed:@"MultiplePhotos"] inRect:CGRectMake(11, 11, 63, 63)]; }else { cell.imageView.image = [UIImage imageNamed:@"placeholder2"]; } NSMutableString *sightsSummary = [NSMutableString stringWithCapacity:[guideRecord.sights count]]; for (Sight *sight in guideRecord.sights) { if ([sight.name length]) { if ([sightsSummary length]) { [sightsSummary appendString:@", "]; } [sightsSummary appendString:sight.name]; } } if ([sightsSummary length]) { [sightsSummary appendString:@"."]; } cell.sightsTextLabel.text = sightsSummary; cell.detailTextLabel.text = [NSString stringWithFormat:NSLocalizedString(@"%i", nil) , [guideRecord.sights count]]; cell.detailTextLabel.hidden = NO; // cell.textLabel.alpha = 0.7; NSPredicate *enabledSightPredicate = [NSPredicate predicateWithFormat:@"notify == YES"]; NSArray *sightsEnabled = [[[guideRecord.sights array] filteredArrayUsingPredicate:enabledSightPredicate]mutableCopy]; NSPredicate *visitedSightPredicate = [NSPredicate predicateWithFormat:@"visited == YES"]; NSArray *sightsVisited = [[[guideRecord.sights array] filteredArrayUsingPredicate:visitedSightPredicate]mutableCopy]; if ([sightsEnabled count] > 0) { NSLog(@"green_badge"); cell.notifyIV.image = [UIImage imageNamed:@"green_badge"]; } else if (sightsVisited.count == 0) { NSLog(@"new_badge"); cell.notifyIV.image = [UIImage imageNamed:@"new_badge"]; } else { cell.notifyIV.image = nil; } } else { cell.notifyIV.hidden = YES; // cell.textLabel.textColor = RGB(0, 50, 140); cell.detailTextLabel.hidden = YES; cell.sightsTextLabel.text = nil; } return cell; }

  • Multiplication of 2 positive numbers giving a negative result

    - by krandiash
    My program is an implementation of a bloom filter. However, when I'm storing my hash function results in the bit array, the function (of the form f(i) = (a*i + b) % m where a,b,i,m are all positive integers) is giving me a negative result. The problem seems to be in the calculation of a*i which is coming out to be negative. Ignore the print statements in the code; those were for debugging. Basically, the value of temp in this block of code is coming out to be negative and so I'm getting an ArrayOutOfBoundsException. m is the bit array length, z is the number of hash functions being used, S is the set of values which are members of this bloom filter and H stores the values of a and b for the hash functions f1, f2, ..., fz. public static int[] makeBitArray(int m, int z, ArrayList<Integer> S, int[] H) { int[] C = new int[m]; for (int i = 0; i < z; i++) { for (int q = 0; q < S.size() ; q++) { System.out.println(H[2*i]); int temp = S.get(q)*(H[2*i]); System.out.println(temp); System.out.println(S.get(q)); System.out.println(H[2*i + 1]); System.out.println(m); int t = ((H[2*i]*S.get(q)) + H[2*i + 1])%m; System.out.println(t); C[t] = 1; } } return C; } Any help is appreciated.

  • MFC Combo-Box Control is not showing the full list of items when I click the drop-down menu...

    - by shan23
    I'm coding an app in MSVS 2008, which has a ComboBox control which I initialize thru the code as below: static char* OptionString[4] = {"Opt1", "Opt2", "Opt3", "Opt4"}; BOOL CMyAppDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here m_Option.AddString(OptionString[0]); m_Option.AddString(OptionString[1]); m_Option.AddString(OptionString[2]); m_Option.AddString(OptionString[3]); m_Option.SetCurSel(0); return TRUE; // return TRUE unless you set the focus to a control } Now, when I build the app and click the down-arrow, the drop-down box shows the first option ONLY(since I've selected that thru my code). But, if i press down-arrow key on keyboard, it cycles thru the options in the order I've inserted, but never does it show more than 1 option in the box. So, In case an user wants to select option3, he has to cycle through options 1 and 2 !! Though once I select any option using the keyboard, the appropriate event handlers are fired, I'm miffed by this behaviour , as is understandable. I'm listing the properties of the combo-box control as well - only the properties that are true(rest are set to false): Type - Dropdown Vertical Scrollbar Visible Tabstop This has bugged me for weeks now. Can anyone pls enlighten me ?

  • Expression Tree with Property Inheritance causes an argument exception

    - by Adam Driscoll
    Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.
