  • What does it mean to "preconcat" a matrix?

    - by Brad Hein
    In reviewing: http://developer.android.com/reference/android/graphics/Canvas.html I'm wondering translate(): "preconcat the current matrix with the specified translation" -- what does this mean? I can't find a good definition of "preconcat" anywhere on the internet! The only place I can find it is in the Android Source - I'm starting to wonder if they made it up? :) I'm familiar with "concat" or concatenate, which is to append to, so what is a pre-concat?

  • Common DataAnnotations in ASP.Net MVC2

    - by Scott Mayfield
    Howdy, I have what should be a simple question. I have a set of validations that use System.CompontentModel.DataAnnotations . I have some validations that are specific to certain view models, so I'm comfortable with having the validation code in the same file as my models (as in the default AccountModels.cs file that ships with MVC2). But I have some common validations that apply to several models as well (valid email address format for example). When I cut/paste that validation to the second model that needs it, of course I get a duplicate definition error because they're in the same namespace (projectName.Models). So I thought of removing the common validations to a separate class within the namespace, expecting that all of my view models would be able to access the validations from there. Unexpectedly, the validations are no longer accessible. I've verified that they are still in the same namespace, and they are all public. I wouldn't expect that I would have to have any specific reference to them (tried adding using statement for the same namespace, but that didn't resolve it, and via the add references dialog, a project can't reference itself (makes sense). So any idea why public validations that have simply been moved to another file in the same namespace aren't visible to my models? CommonValidations.cs using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Text.RegularExpressions; namespace ProjectName.Models { public class CommonValidations { [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true, Inherited = true)] public sealed class EmailFormatValidAttribute : ValidationAttribute { public override bool IsValid(object value) { if (value != null) { var expression = @"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$"; return Regex.IsMatch(value.ToString(), expression); } else { return false; } } } } } And here's the code that I want to use the validation from: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using Growums.Models; namespace ProjectName.Models { public class PrivacyModel { [Required(ErrorMessage="Required")] [EmailFormatValid(ErrorMessage="Invalid Email")] public string Email { get; set; } } }

  • Django: Password protect photo url's?

    - by MikeN
    From my Django application I want to serve up secure photos. The photos are not for public consumption, I only want logged in users to have the ability to view them. I don't want to rely on obfuscated file id's (giving a photo a UUID of a long number) and count on that being hidden in my media folder. How would I store a photo securely on disk in my database and only stream it out to an authenticated session?

  • [self autorelease] not doing dealloc

    - by jonydep
    i have this in the superview: mySubView = [[MySubView alloc] init]; [self addSubview:mySubView]; [mySubView release]; then at some point later, in the sub view, this: [self removeFromSuperview]; when i debug it, i notice that the dealloc for the subview is never called, even though i'm fairly sure the reference count should be 0. any ideas why this might be? thanks.

  • How can i display a MFC CHtmlView inside a dialog?

    - by Lothar
    I found a lot of links on the internet for this question but i don't understand their (partial) solutions. One of the main problems seems that i'm builing all dialogs by hand without dialog resource files or the Visual Studio Application Wizards. So i would need pure C++ code that i can type into my Editor. There is also some reference to a "CWebBrowser2" control, but a grep on the VC directory does not give me any results, so where can i find this?

  • SmtpClient.Send() complains of incorrect no of overloads when passing in MailMessage object

    - by dotnetdev
    Hi, I have this code written in .NET 4.0 using VS2010 Ultimate Beta 2: smtpClient.Send(mailMsg); smtpClient is a reference to SmtpClient (I have the relevant references added), and likewise for mailMsg (is MailMessage) - there are no errors stating anything like check for missing assemblies. However, I keep getting an error saying that I have the incorrect no of overloads, when SmtpClient takes either a MailMessage object or the To address, From address, Subject, etc. Why doesn't this code work? Totally confused. Thanks

  • How to bind DataTable to Chart series?

    - by user175908
    Hello, How to do bind data from DataTable to Chart series? I get null reference exception. I tried binding with square brackets and it did not worked either. So, how to do the binding? Thanks. P.S: I included DataGrid XAML and CS which works just fine. Converting data to List<KeyValuePair<string,int>> works good but it is kinda slow and is unnessesary trash in code. I use WPFToolkit (the latest version). XAML: <Window x:Class="BindingzTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="606" Width="988" xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"> <Grid Name="LayoutRoot"> <charting:Chart Title="Letters and Numbers" VerticalAlignment="Top" Height="400"> <charting:Chart.Series> <charting:ColumnSeries Name="myChartSeries" IndependentValueBinding="{Binding Letter}" DependentValueBinding="{Binding Number}" ItemsSource="{Binding}" /> </charting:Chart.Series> </charting:Chart> <DataGrid Name="myDataGrid" VerticalAlignment="Stretch" Margin="0,400,0,50" ItemsSource="{Binding}" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTextColumn Header="Letter" Binding="{Binding Letter}"/> <DataGridTextColumn Header="Number" Binding="{Binding Number}"/> </DataGrid.Columns> </DataGrid> <Button Content="Generate" HorizontalAlignment="Left" Name="generateButton" Width="128" Click="GenerateButtonClicked" Height="52" VerticalAlignment="Bottom" /> </Grid> CS: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } DataTable GenerateMyTable() { var myTable = new DataTable("MyTable"); myTable.Columns.Add("Letter"); myTable.Columns.Add("Number"); myTable.Rows.Add("A", 500); myTable.Rows.Add("B", 400); myTable.Rows.Add("C", 500); myTable.Rows.Add("D", 600); myTable.Rows.Add("E", 300); myTable.Rows.Add("F", 200); return myTable; } private void GenerateButtonClicked(object sender, RoutedEventArgs e) { var myGeneratedTable = GenerateMyTable(); myDataGrid.DataContext = myGeneratedTable; myChartSeries.DataContext = myGeneratedTable; // Calling this throws "Object reference not set to an instance of an object" exception } }

  • How do you hyperlink to Word 2007 help pages?

    - by Jeremy Rudd
    I want to hyperlink to a page within the Word 2007 Object Model Reference documentation, that ships with Word 2007. These are webpages that use the ms-help:// protocol that Firefox cannot understand. So I wanted to specify the ms-help:// path of the help page as a command line argument to the viewer, CLVIEW.EXE. C:\Program Files\Microsoft Office\Office12\CLVIEW.EXE Anybody know the command line syntax for this?

  • MPMoviePlayerController doesn't implement MPMediaPlayback protocal as advertised?

    - by goren
    I'm trying to use the MPMediaPlayback protocol's currentPlaybackRate() to slow down a video. I'm confused though as the class MPMoviePlayerController states that: You can control most aspects of playback programmatically using the methods and properties of the MPMediaPlayback protocol, to which this class conforms. Except just above in the header here: http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html it doesn't seem to. All I want to do is slow down the playback rate for a video.

  • php if clause inside foreach not retrieving data correctly

    - by Mike
    Here's my issue: In my controller, I want to grab user input from a form. I then parse the input, and compare it to database values to ensure I'm grabbing the correct input. I simply want to match the user's answers to the question, grab the user ID, the question ID, and then determine if the answer applies to a multiple choice or checkbox question, or something else. I take those values and insert them into the answer table. Ignore the waiver stuff. I'll test that once I get the answers input correctly. // add answers and waiver consent records try { $answerArray = array(); $waiverArray = array(); // retrieve answers, waiver consents, and the question ID's from form object foreach ($formData as $key => $value) { $parts = explode("_", $key); if ($parts[0] == 'question') { array_push($answerArray, $value); } if ($parts[0] == 'waiverTitle') { array_push($waiverArray, $value); } } $questions = new Model_DbTable_Questions(); $questionResults = $questions->getQuestionResults($session->idEvent); foreach ( $questionResults as $qr ) { if ($qr ['questionType'] == 'multipleChoice' || $qr ['questionType'] == 'checkBox') { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], null, $aa ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } else { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], $aa, null ); echo count ( $answerData ) . ', ' . $qr ['questionType'] . ', ' . $aa . '<br />'; } } } } catch (Zend_Db_Statement_Exception $e) { $e->getMessage(); throw $e; } From my test data, I expect to get 2 records that match the multiple choice and checkbox criteria, and 1 record for text in the ELSE clause like this: 3, checkbox, 1 3, multipleChoice, 1 3, text, question_2 What I get is a 3x3 Cartesian product, 3 question elements each with the 3 possible answers like this output from the echo statements: 4, checkBox, 1 4, checkBox, 1 4, checkBox, question_2 4, multipleChoice, 1 4, multipleChoice, 1 4, multipleChoice, question_2 4, text, 1 4, text, 1 4, text, question_2 I've tried placing the IF clause inside the inner foreach, but I get the same results. I've been staring at this problem for way too long and cannot see what I'm doing wrong. Your kind assistance would be greatly appreciated. Please let me know if my request requires more clarification.

  • OSGI classcast exception on felix

    - by Nico
    Hi, i'm fairly new to osgi and am trying to get a functional proof of concept together. The setup is that my common api is created in a bundle creatively named common-api.jar with no bundle activator, but it exports all it's interfaces. the one of interest in this situation is DatabaseService.java. I then have a Second bundle called systemx-database-service. That implements the database service interface. this works fine as in the activator of the implementation bundle i test the connection to the database and select some arbitraty values. I also register the service i want to be available to the other bundle's like so: context.registerService(DatabaseService.class.getName(), new SystemDatabaseServiceImpl(context), new Properties()); The basic idea being when you look for a service reference for a Database service you'll get back the SystemDatabaseService implementation. When i do a inspect service the output it this: -> inspect s c 69 System Database Service (69) provides services: ---------------------------------------------- objectClass = za.co.xxx.xxx.common.api.DatabaseService service.id = 39 which would lead me to believe that if i do this in a test bundle: context.getService(context.getServiceReference(DatabaseService.class)); i should get back an instance of DatabaseService.class, but alas no such luck. it simply seems like it cannot find the service. stick with me here my story gets stranger. figuring there is no where to go but up i wrote this monstrosity: for (Bundle bundle : bundles) { if (bundle.getSymbolicName().equals("za.co.xxx.xxx.database-service")) { ServiceReference[] registeredServices = bundle.getRegisteredServices(); for (ServiceReference ref : registeredServices) { DatabaseService service = (DatabaseService) context.getService(ref); // use service here. } } } } now i can actually see the service reference, but i get this error java.lang.ClassCastException: za.co.xxx.xxx.database.service.impl.SystemDatabaseServiceImpl cannot be cast to za.co.xxx.xx.common.api.DatabaseService which is crazy since the implementation clearly implements the interface! Any help would be appreciated. Please keep in mind i'm very new at the osgi way of thinking so my whole approach here might be flawed. oh. if anyone wants the manifests i can post them. and i'm using the maven-bnd-plugin to build and executing on felix. thanks Nico

  • DDD: Getting aggregate roots for other aggregates

    - by Ed
    I've been studying DDD for the past 2 weeks, and one of the things that really stuck out to me was how aggregate roots can contain other aggregate roots. Aggregate roots are retrieved from the repository, but if a root contains another root, does the repository have a reference to the other repository and asks it to build the subroot?
