  • Date formatting using data annotations for a dataform in Silverlight

    - by Aim Kai
    This is probably got a simple answer to it, but I am having problems just formatting the date for a dataform field.. <df:DataForm x:Name="Form1" ItemsSource="{Binding Mode=OneWay}" AutoGenerateFields="True" AutoEdit="True" AutoCommit="False" CommitButtonContent="Save" CancelButtonContent="Cancel" CommandButtonsVisibility="Commit" LabelPosition="Top" ScrollViewer.VerticalScrollBarVisibility="Disabled" EditEnded="NoteForm_EditEnded"> <df:DataForm.EditTemplate> <DataTemplate> <StackPanel> <df:DataField> <TextBox Text="{Binding Title, Mode=TwoWay}"/> </df:DataField> <df:DataField> <TextBox Text="{Binding Description, Mode=TwoWay}" AcceptsReturn="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="" TextWrapping="Wrap" SizeChanged="TextBox_SizeChanged"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding Username}"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding DateCreated}"/> </df:DataField> </StackPanel> </DataTemplate> </df:DataForm.EditTemplate> </df:DataForm> I have bound this to a note class which has the annotation for field DateCreated: /// <summary> /// Gets or sets the date created of the noteannotation /// </summary> [Display(Name="Date Created")] [Editable(false)] [DisplayFormat(DataFormatString = "{0:u}", ApplyFormatInEditMode = true)] public DateTime DateCreated { get; set; } Whatever I set the dataformatstring it comes back as: eg 4/6/2010 10:02:15 AM I want this formatted as yyyy-MM-dd HH:mm:ss I have tried the custom format above {0:yyyy-MM-dd hh:mm:ss} but it remains the same output. The same happens for {0:u} or {0:s}. Any help would be gratefully received. :)

  • Algorithm design, "randomising" timetable schedule in Python although open to other languages.

    - by S1syphus
    Before I start I should add I am a musician and not a native programmer, this was undertook to make my life easier. Here is the situation, at work I'm given a new csv file each which contains a list of sound files, their length, and the minimum total amount of time they must be played. I create a playlist of exactly 60 minutes, from this excel file. Each sample played the by the minimum number of instances, but spread out from each other; so there will never be a period where for where one sound is played twice in a row or in close proximity to itself. Secondly, if the minimum instances of each song has been used, and there is still time with in the 60 min, it needs to fill the remaining time using sounds till 60 minutes is reached, while adhering to above. The smallest duration possible is 15 seconds, and then multiples of 15 seconds. Here is what I came up with in python and the problems I'm having with it, and as one user said its buggy due to the random library used in it. So I'm guessing a total rethink is on the table, here is where I need your help. Whats is the best way to solve the issue, I have had a brief look at things like knapsack and bin packing algorithms, while both are relevant neither are appropriate and maybe a bit beyond me.

  • NHibernate SubclassMap gives DuplicateMappingException

    - by stiank81
    I'm using NHibernate to handle my database - with Fluent configuration. I'm not using Automappings. All mappings are written explicitly, and everything is working just fine. Now I wanted to add my first mapping to a subclass, using the SubclassMap, and I run into problems. With the simplest possible setup an Nhibernate DuplicateMappingException is thrown, saying that the subclass is mapped more than once: NHibernate.MappingException : Could not compile the mapping document: (XmlDocument) ---- NHibernate.DuplicateMappingException : Duplicate class/entity mapping MyNamespace.SubPerson I get this with my simple classes written for testing: public class Person { public int Id { get; set; } public string Name { get; set; } } public class SubPerson : Person { public string Foo { get; set; } } With the following mappings: public class PersonMapping : ClassMap<Person> { public PersonMapping() { Not.LazyLoad(); Id(c => c.Id); Map(c => c.Name); } } public class SubPersonMapping : SubclassMap<SubPerson> { public SubPersonMapping() { Not.LazyLoad(); Map(m => m.Foo); } } Any idea why this is happening? If there were automappings involved I guess it might have been caused by the automappings adding a mapping too, but there should be no automapping. I create my database specifying a fluent mapping: private static ISession CreateSession() { var cfg = Fluently.Configure(). Database(SQLiteConfiguration.Standard.ShowSql().UsingFile("unit_test.db")). Mappings(m => m.FluentMappings.AddFromAssemblyOf<SomeClassInTheAssemblyContainingAllMappings>()); var sessionSource = new SessionSource(cfg.BuildConfiguration().Properties, new TestModel()); var session = sessionSource.CreateSession(); _sessionSource.BuildSchema(session); return session; } Again; note that this only happens with SubclassMap. ClassMap's are working just fine!

  • What is wrong with this solution? (Perm-Missing-Elem codility test)

    - by user2956907
    I have started playing with codility and came across this problem: A zero-indexed array A consisting of N different integers is given. The array contains integers in the range [1..(N + 1)], which means that exactly one element is missing. Your goal is to find that missing element. Write a function: int solution(int A[], int N); that, given a zero-indexed array A, returns the value of the missing element. For example, given array A such that: A[0] = 2 A[1] = 3 A[2] = 1 A[3] = 5 the function should return 4, as it is the missing element. Assume that: N is an integer within the range [0..100,000]; the elements of A are all distinct; each element of array A is an integer within the range [1..(N + 1)]. Complexity: expected worst-case time complexity is O(N); expected worst-case space complexity is O(1), beyond input storage (not counting the storage required for input arguments). I have submitted the following solution (in PHP): function solution($A) { $nr = count($A); $totalSum = (($nr+1)*($nr+2))/2; $arrSum = array_sum($A); return ($totalSum-$arrSum); } which gave me a score of 66 of 100, because it was failing the test involving large arrays: "large_range range sequence, length = ~100,000" with the result: RUNTIME ERROR tested program terminated unexpectedly stdout: Invalid result type, int expected. I tested locally with an array of 100.000 elements, and it worked without any problems. So, what seems to be the problem with my code and what kind of test cases did codility use to return "Invalid result type, int expected"?

  • resizing row's height in QTreeWidget/QTreeView

    - by serge
    Hi everyone, I have some problems with sizing row's height in QTreeWidget. I use QStyledItemDelegate with QPlainTextEdit. During editing text in QPlainTextEdit i check for changes with a help of: rect = self.blockBoundingRect(self.firstVisibleBlock()) and if text's height changes i resize editor size and need row in QTreeWidget also resizing. But i don't know how to inform TreeWidget or a Delegate about changes. I tried to initialize editor with index, that i could use in a future, but Delegate creates new editor every time and i failed to use signals. Also I used following function to catch resize event, but it' doesn't: bool QAbstractItemDelegate::editorEvent ( QEvent * event, QAbstractItemModel * model, const QStyleOptionViewItem & option, const QModelIndex & index ) How can i bound editor's size changes with TreeWidget? And one more thing, by default all items (cells) in TreeWidget have -1 or some big value as default width. I need whole text in cell to be visible, so how can i limit cells width only by visible range and make it expand in height? I want for it the same behavior as in instance a table in MSWord. Thank you in advance, Serge

  • Xdebug configuration with PHP fastcgi and eclipse?

    - by mac
    I have been using eclipse-pdt in conjunction with xdebug and apache without problems, for over one year. Things worked flawlessly and I could do all the interactive debugging I wanted from within eclipse (using my own machine as a server). Now I switched from apache to nginx (and therefore PHP runs now not as an Apache service but as fast-cgi) and I can't find a way to configure eclipse to work nicely with xdebug. I am neither sure if the problem is with xdebug or with eclipse (or both) to be sure. In the eclipse configuration I already changed the reference to the PHP configuration file to /etc/php5/cli/php.ini. Attempts with php.ini version 1 With the following php.ini file zend_extension=/usr/lib/php5/20060613/xdebug.so I see that xdebug is working (for example if I do a var_dump() I get the xdebug version of it, not the plain PHP one) I can't have the interactive debugging from eclipse: the browser opens up and loads the page completely with the typical URL containing ...?XDEBUG_SESSION_START=ECLIPSE_DBGP&KEY=..., but the program execution does not stop at breakpoints In the bottom-right corner of eclipse I see a suspicious message: *"Launching =put_the_name_of_my_project_here=: 57%"* that alternates with the "refreshing workspace" one. Attempts with php.ini version 2 If I use this other version of the file (which is what it worked until I switched to nginx): zend_extension=/usr/lib/php5/20060613/xdebug.so xdebug.remote_enable=On xdebug.remote_autostart=On xdebug.remote_handler=dbgp xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.remote_mode=req I can't access any page of my sites at all. Any help or suggestion appreciated, thank you in advance for your time!

  • Applying Test Driven Development to a tightly coupled architecture

    - by Chris D
    Hi all, I've recently been studying TDD, attended a conference and have dabbled in few tests and already I'm 100% sold, I absolutely love it TDD. As a result I've raised this with my seniors and they are prepared to give it a chance, so they have tasked me with coming up with a way to implement TDD in the development of our enterprise product. The problem is our system has evolved since the days of VB6 to .NET and implements alot of legacy technology and some far from best practice development techniques i.e. alot of business logic in the ASP.NET code behind and client script. The largest problem however is how our classes are tightly coupled with database access; properties, methods, constructors - usually has some database access in some form or another. We use an in-house data access code generator tool that creates sqlDataAdapters that gives us all the database access we could ever want, which helps us develop extremely quickly, however, classes in our business layer are very tightly coupled to this data layer - we aren't even close to implementing some form of repository design. This and the issues above have created me all sorts of problems. I have tried to develop some unit tests for some existing classes I've already written but the tests take ALOT longer to run since db access is required, not to mention since we use the MS Enterprise Caching framework I am forced to fake a httpcontext for my tests to run successfully which isn't practical. Also, I can't see how to use TDD to drive the design of any new classes I write since they have to be soo tightly coupled to the database ... help! Because of the architecture of the system it appears I can't implement TDD without some real hack which in my eyes just defeats the aim of TDD and the huge benefits that come with. Does anyone have any suggestions how I could implement TDD with the constraints I'm bound too? or do I need to push the repository design pattern down my seniors throats and tell them we either change our architecture/development methodology or forget about TDD altogether? :) Thanks

  • jquery sortable scroll problem

    - by Sam Vloeberghs
    Hi I'm having problems using the sortable function of jQ:uery UI. The scroll doesn't seem to work.. If the second list ( lists are created on the table rows in a tbody and each tbody is connect ) isn't visible I want it to be possible to scroll towards it for dropping my table row. This is my HTML set up: <ul> <li> <ul> <li> <table class="treeleerling"> <tbody class="oder0"> <tr class="suborder0"> </tr> <tr class="sub1order"> </tr> </tbody> </table> </li> </ul> </li> <li> <ul> <li> <table class="treeleerling"> <tbody class="oder1"> <tr class="suborder0"> </tr> <tr class="suborder1"> </tr> </tbody> </table> </li> </ul> </li> </ul> And jQuery code $(document).ready(function() { $("#left tbody").sortable({ connectWith : '#left tbody', scroll : true, scrollSensitivity: 40, }); }); The sorting works fine, but the scrolling doesnt.. I'm doing something wrong or what? Plz help and advice.. Thx in advance!

  • Windows 7 - Enable Network DTC Access

    - by Russ Clark
    I have a Visual Studio 2010 Windows Forms application in which I start a transaction using the TransactionScope class. I then Receive a message from a Sql Server Broker Services message queue, which works fine. I next try to call a stored procedure from the same database with a call to my data access layer which is a Visual Studio dataset (xsd file). When I make this second call to the database I get the following error message: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B). I've seen several posts on the web that talk about Enabling DTC access through dcomcnfg.exe, and allowing DTC to communicate through Windows Firewall. I've done those things, and am still having this problem. I know our remote database server is setup to Enable DTC access, because we are using similar transactions in other projects built with Visual Studio 2008 on Windows XP and Vista. I think there is something specific about Windows 7 and Visual Studio 2010 causing this problem, but haven't been able to find out what it is. Can anyone help with this problem?

  • asp.net ajax control toolkit combobox displays incorectly when in fieldset with style of position:re

    - by Jon P
    I currently have an Instance of the ASP.net ajax control toolkit combo box residing in a field set with a style of position:releative applied. The control also sits in a very plain table (please no comments about using tables for lay-out, I know it is evil and try to avoid it). There are two problems with the display of the list: The list does not sit flush with the text box. In I.E. 7 (which is the majority of my target audience, intranet where IE7 is the company standard) the list display about 10px below the fieldset, which is what the bottom margin of the fieldset is set to. In FF 2.0 the list sits sinificantly lower and off-set to the right. Below the filed set there is more content in a div, also with a style of position:relative applied. The list from the combo box displays behind the content of this div, which is obviouly an issue. Removing position:releative from the fieldset resolves the display issue of the combo box, but results in other unwanted display side effects. My interim workaround is to specifically restyle this fieldset without the position:absolute style, but I'm hoping for a better solution. Thanks

  • Using oauth2_access_token to get connections in linkedIn

    - by Pedro
    I'm trying to get the connections in linkedIn using their API, but when I try to retrieve the connections I get a 401 unauthorized error. in the official documentation says You must use an access token to make an authenticated call on behalf of a user Make the API calls You can now use this access_token to make API calls on behalf of this user by appending "oauth2_access_token=access_token" at the end of the API call that you wish to make. The API call that I'm trying to do is the following Error -- http://api.linkedin.com/v1/people/~/connections:(id,headline,first-name,last-name)?format=json&oauth2_access_token=access_token I have tried to do it with the following endpoint without any problems.

  • WiX/Windows Installer: Re-install to a new folder

    - by vitalyval
    1. I am using WiX for creating installer and would like to implement the following behaviour: If a user launches msi installer for the product and the product already installed, then wizard works similar to pure (first time) installation with exception of some things (e.g. license aggrement screen is omitted). The wizard should allow for example to change installation folder, select whether to place desktop shortcut,... I tried to do: <Publish Event="ReinstallMode" Value="amus"><![CDATA[INSTALL_MODE = "Change"]]></Publish> <Publish Event="Reinstall" Value="ALL"><![CDATA[INSTALL_MODE = "Change"]]></Publish> But after installation completes: the product is in the same folder, where it was installed first time; desktop icon in the same state as it was after first time install. MSDN says: "Do not attempt to change the target directory path if some components that use the path are already installed for the current user or for a different user". Is there a way to re-install in another forlder and add/remove desktop icon in re-install? 2. Is this normal to use the same KeyPath for some components? For example the same registry values for DeskTop and Programs menu shortcuts? MSDN says: "Two components cannot share the same key path value". But compiling and verifying goes OK. And I did not discover problems using the same keypaths.

  • Android's EditText is hidden when the virtual keyboard is shown and a SurfaceView is involved

    - by Jan
    I have a simple user interface: an EditText should be located below a SurfaceView. I use a RelativeLayout to arrange these two views. Now, when I tap on the EditText to open the virtual keyboard the SurfaceView slides up but the EditText is hidden and does not show the typed string. To reproduce, use the following layout XML code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent"> <SurfaceView android:id="@+id/SurfaceView01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </SurfaceView> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" android:selectAllOnFocus="true" android:textStyle="normal" android:singleLine="true"> </EditText> </RelativeLayout> The main Activity class only needs to show the layout. When I start the program and tap the EditText, the virtual keyboard appears but the EditText field is gone. Maybe the RelativeLayout is causing the problems, but I don't know how to reproduce the same layout with another Layout class. Any suggestions are welcome, I really appreciate your help. Thanks. Edit: Here are two screenshots, one showing the EditText at the bottom without virtual keyboard, one with virtual keyboard but with no EditText. It is interesting to note that the SurfaceView and the EditText actually shift upward, the EditText just disappears. BTW this also happens to a button if it is next to the EditText. EditText below a SurfaceView (left); EditText is gone (right)

  • Generate authenticated CMSEnvelopedData Messages with bouncycastle

    - by levinalex
    I am trying to encrypt data with a password and store it inside a ASN.1 encoded CMS message (using C# and BouncyCastle 1.4) The code I have seems to have two problems: the data does not seem to be signed with a HMAC, so when I tamper with the encodedData (by enabling the commented out line), the decryption still succeeds. when I decrypt the data I have tampered with, I get beck corrupted plain text. However only a two blocks of plaintext data are corrupted. This seems to suggest that the encryption does not actually use CBC mode. (edit: disregard the second point, this is exactly how CBC is supposed to work) This is what I am testing with: public void TestMethod1() { byte[] data = new byte[1024]; // plaintext: a list of zeroes CmsEnvelopedDataGenerator generator = new CmsEnvelopedDataGenerator(); CmsPbeKey encryptionKey = new Pkcs5Scheme2PbeKey("foo", new byte[] { 1, 2, 3 }, 2048); generator.AddPasswordRecipient(encryptionKey, CmsEnvelopedDataGenerator.Aes256Cbc); CmsProcessableByteArray cmsByteArray = new CmsProcessableByteArray(data); CmsEnvelopedData envelopeData = generator.Generate(cmsByteArray, CmsEnvelopedDataGenerator.Aes256Cbc); byte[] encodedData = envelopeData.GetEncoded(); // encodedData[500] = 10; // tamper with the data RecipientID recipientID = new RecipientID(); CmsEnvelopedData decodedEnvelopeData = new CmsEnvelopedData(encodedData); RecipientInformation recipient = decodedEnvelopeData.GetRecipientInfos().GetFirstRecipient(recipientID); byte[] data2 = recipient.GetContent(encryptionKey); CollectionAssert.AreEqual(data, data2); } What am I doing wrong? What would be the correct way to write this?

  • Mixing Objective-C and C++

    - by helixed
    Hello, I'm trying to mix together some Objective-C code with C++. I've always heard it was possible, but I've never actually tried it before. When I try to compile the code, I get a bunch of errors. Here's a simple example I've created which illustrates my problems: AView.h #import <Cocoa/Cocoa.h> #include "B.h" @interface AView : NSView { B *b; } -(void) setB: (B *) theB; @end AView.m #import "AView.h" @implementation AView - (id)initWithFrame:(NSRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code here. } return self; } - (void)drawRect:(NSRect)dirtyRect { // Drawing code here. } -(void) setB: (B *) theB { b = theB; } @end B.h #include <iostream> class B { B() { std::cout << "Hello from C++"; } }; Here's the list of errors I get when I try to compile this: /Users/helixed/Desktop/Example/B.h:1:0 /Users/helixed/Desktop/Example/B.h:1:20: error: iostream: No such file or directory /Users/helixed/Desktop/Example/B.h:3:0 /Users/helixed/Desktop/Example/B.h:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'B' /Users/helixed/Desktop/Example/AView.h:5:0 /Users/helixed/Desktop/Example/AView.h:5: error: expected specifier-qualifier-list before 'B' /Users/helixed/Desktop/Example/AView.h:8:0 /Users/helixed/Desktop/Example/AView.h:8: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:26:0 /Users/helixed/Desktop/Example/AView.m:26: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:27:0 /Users/helixed/Desktop/Example/AView.m:27: error: 'b' undeclared (first use in this function) All I'm doing to compile this right now is using the default compiler built into Xcode. I didn't edit the Cocoa Application template in any way other than adding the two files I created and chaing the NSView to AView in the xib file. Could somebody please tell me what I'm doing wrong? Thanks, helixed

  • Linking to MSVC DLL from MinGW

    - by IndigoFire
    I'm trying to link the LizardTech GeoExpress DSDK into my own application. I use gcc so that we can compile on for platforms. On Linux and Mac this works easily: they provide a static library (libltidsdk.a) and headers and all that we have to do is use them. Compiling for windows isn't so easy. They've built the library using Microsoft Visual Studio, and we use MinGW. I've read the MinGW FAQ, and I'm running into the problems below. The library is all C++, so my first question: is this even possible? Just linking against the dll as provided yields "undefined reference" errors for all of the C++ calls (constructors, desctructors, methods, etc). Based on the MinGW Wiki: http://www.mingw.org/wiki/MSVC%5Fand%5FMinGW%5FDLLs I should be able to use the utility reimp to convert a .lib into something useable. I've tried all of the .lib files provided by LizardTech, and they all give "invalid or corrupt import library". I've tried both version 0.4 and 0.3 of the reimp utility. Using the second method described in the wiki, I've run pexport and dlltool over the dll to get a .a archive, but that produces the same undefined references. BTW: I have read the discussion below. It left some ambiguity as to whether this is possible, and given the MinGW Wiki page it seems like this should be doable. If it is impossible, that's all I need to know. If it can be done, I'd like to know how I can get this to happen. stackoverflow.com/questions/1796209/how-to-link-to-vs2008-generated-libs-from-g Thanks!

  • Making flexible C# code in MVC2 for Stored Procedures

    - by cc0
    Thanks to Darin Dimitrov's suggestion I got a big step further in understanding good MVC code, but I'm having some problems making it flexible. I implemented Darin's suggested solution, and it works perfectly for single controllers. However I'm having some trouble implementing it with some flexibility. What I'm looking for is this; To be able to make dynamic column names in json Instead of using "Column1: 'value', ..." and "Column2: 'value', ..." inside the json, I'd like to use for example "id: 'value', ..." and "place: 'value' ..." for one stored procedure, and "animal" and "type" in another (inside the json format). To be able to make dynamic amounts of columns dependent on which stored procedure is called Some stored procedures I'll want to read more than 2 rows from, is there a smart way of accomplishing that? To be able to make numeric (floats and integers) rows from the database be presented inside the json without quotes Like this (name and age); { Column1: "John", Column2: 53 }, I would be very grateful for any feedback and suggestions / code examples I can get here. Even imperfect ones.

  • WPF Databound RadioButton ListBox

    - by Mark
    I am having problems getting a databound radiobutton listbox in WPF to respond to user input and reflect changes to the data it's bound to (i.e., to making changes in the code). The user input side works fine (i.e., I can select a radiobutton and the list behaves as expected). But every attempt to change the selection in code fails. Silently (i.e., no exception). Here's the relevant section of the XAML (I think): <Setter Property="ItemContainerStyle"> <Setter.Value> <Style TargetType="{x:Type ListBoxItem}" > <Setter Property="Margin" Value="2" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ListBoxItem}"> <Border Name="theBorder" Background="Transparent"> <RadioButton Focusable="False" IsHitTestVisible="False" IsChecked="{Binding Path=IsSelected, RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}" > <ContentPresenter /> </RadioButton> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Setter.Value> I bind the listbox to a List of SchoolInfo objects. SchoolInfo contains a property called IsSelected: public bool IsSelected { get { return isSelected; } set { if( value != isSelected ) { isSelected = value; this.OnPropertyChanged("IsSelected"); } } } The OnPropertyChanged() stuff was something I put in during my experimentation. It doesn't solve the problem. Things like the following fail: ((SchoolInfo) lbxSchool.Items[1]).IsSelected = true; lbxSchool.SelectedIndex = 1; They fail silently -- no exception is thrown, but the UI doesn't show the item being selected.

  • Start TabActivity from ListActivity (which is content of parent TabActivity) in Android

    - by barmaleikin
    Hi guys, I have problems with switching between activities. I have two TabActivities (A and B), each of of tab activity has 4 tabs with ListActivity. I am trying to show B activity onListItemClick. Code on click is: Intent intent = new Intent(getApplicationContext(), TabBActivity.class); startActivity(intent); My manifest file is following: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="true"> <activity android:name=".SplashScreen" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".TabAActivity"> <intent-filter> <action android:name="com.TabAActivity" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".TabAListActivityA" android:label="AA"/> <activity android:name=".TabAListActivityB" android:label="AB"/> <activity android:name=".TabAListActivityC" android:label="AC"/> <activity android:name=".TabBActivity" android:label="B"/> <activity android:name=".TabAListBctivityA" android:label="BA"/> <activity android:name=".TabAListBctivityB" android:label="BB"/> <activity android:name=".TabAListBctivityC" android:label="BC"/> </application> </manifest> Is my manifest correct or maybe something is wrong with code? I would appreciate any help on this topic.

  • Model validation with enumerable properties in Asp.net MVC2 RTM

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • How can I force Javascript garbage collection in IE? IE is acting very slow after AJAX calls & DOM

    - by RenderIn
    I have a page with chained drop-downs. Choosing an option from the first select populates the second, and choosing an option from the second select returns a table of matching results using the innerHtml function on an empty div on the page. The problem is, once I've made my selections and a considerable amount of data is brought onto the page, all subsequent Javascript on the page runs exceptionally slowly. It seems as if all the data I pulled back via AJAX to populate the div is still hogging a lot of memory. I tried setting the return object which contains the AJAX results to null after calling innerHtml but with no luck. Firefox, Safari, Chrome and Opera all show no performance degradation when I use Javascript to insert a lot of data into the DOM, but in IE it is very apparent. To test that it's a Javascript/DOM issue rather than a plain old IE issue, I created a version of the page that returns all the results on the initial load, rather than via AJAX/Javascript, and found IE had no performance problems. FYI, I'm using jQuery's jQuery.get method to execute the AJAX call. EDIT This is what I'm doing: <script type="text/javascript"> function onFinalSelection() { var searchParameter = jQuery("#second-select").val(); jQuery.get("pageReturningAjax.php", {SEARCH_PARAMETER: searchParameter}, function(data) { jQuery("#result-div").get(0).innerHtml = data; //jQuery("#result-div").html(data); //Tried this, same problem data = null; }, "html"); } </script>

  • jqGrid local data manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks edit I've solved this with the following code for the delete navGrid button }).navGrid('#pager', {add:true, del:true, refresh:false, search:false}, { ... }, ##edit parameters { ... }, ##add parameters {reloadAfterSubmit:false, clearAfterAdd:false, afterComplete: function () { ## clear and readd the row data so the row ids are sequential var savedData= $("#inputgrid").jqGrid('getRowData'); $("#inputgrid").jqGrid('clearGridData'); $("#inputgrid").jqGrid('addRowData', 'rn', savedData); } } ##delete parameters ); Basically just saving the grid data and then re-adding it so that the rowids are sequential again. For some reason it causes the row numbers down the left side to go start from 2 instead of one. Edit this was solved by using the latest jqGrid code in GitHub (27th April 2010)

  • Mixing Objective-C and C++

    - by helixed
    I'm trying to mix together some Objective-C code with C++. I've always heard it was possible, but I've never actually tried it before. When I try to compile the code, I get a bunch of errors. Here's a simple example I've created which illustrates my problems: AView.h #import <Cocoa/Cocoa.h> #include "B.h" @interface AView : NSView { B *b; } -(void) setB: (B *) theB; @end AView.m #import "AView.h" @implementation AView - (id)initWithFrame:(NSRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code here. } return self; } - (void)drawRect:(NSRect)dirtyRect { // Drawing code here. } -(void) setB: (B *) theB { b = theB; } @end B.h #include <iostream> class B { B() { std::cout << "Hello from C++"; } }; Here's the list of errors I get when I try to compile this: /Users/helixed/Desktop/Example/B.h:1:0 /Users/helixed/Desktop/Example/B.h:1:20: error: iostream: No such file or directory /Users/helixed/Desktop/Example/B.h:3:0 /Users/helixed/Desktop/Example/B.h:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'B' /Users/helixed/Desktop/Example/AView.h:5:0 /Users/helixed/Desktop/Example/AView.h:5: error: expected specifier-qualifier-list before 'B' /Users/helixed/Desktop/Example/AView.h:8:0 /Users/helixed/Desktop/Example/AView.h:8: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:26:0 /Users/helixed/Desktop/Example/AView.m:26: error: expected ')' before 'B' /Users/helixed/Desktop/Example/AView.m:27:0 /Users/helixed/Desktop/Example/AView.m:27: error: 'b' undeclared (first use in this function) All I'm doing to compile this right now is using the default compiler built into Xcode. I didn't edit the Cocoa Application template in any way other than adding the two files I created and chaing the NSView to AView in the xib file. Could somebody please tell me what I'm doing wrong? Thanks, helixed
