  • UISplitViewController in a TabBar?

    - by Madhup
    Hi all, I am in kind of situation that I need to start with a tab based application and in that I need a split view for one or more tabs. But it seems that split view controller object can not be added to the tabbarController. (Although tabbar object can be added to the splitviewcontroller). The problem can be seen otherways: I have a full screen in the left part I have a table view when any row is selected in the table a popover should come out pointing that row. I think I am clear in what I explained. So guys any ideas or work arounds? Please let me know if I am not clear in my question. Thanks, Madhup

  • Remove duplicates from DataTable and custom IEqualityComparer<DataRow>

    - by abatishchev
    How have I to implement IEqualityComparer<DataRow> to remove duplicates rows from a DataTable with next structure: ID primary key, col_1, col_2, col_3, col_4 The default comparer doesn't work because each row has it's own, unique primary key. How to implement IEqualityComparer<DataRow> that will skip primary key and compare only data remained. I have something like this: public class DataRowComparer : IEqualityComparer<DataRow> { public bool Equals(DataRow x, DataRow y) { return x.ItemArray.Except(new object[] { x[x.Table.PrimaryKey[0].ColumnName] }) == y.ItemArray.Except(new object[] { y[y.Table.PrimaryKey[0].ColumnName] }); } public int GetHashCode(DataRow obj) { return obj.ToString().GetHashCode(); } } and public static DataTable RemoveDuplicates(this DataTable table) { return (table.Rows.Count > 0) ? table.AsEnumerable().Distinct(new DataRowComparer()).CopyToDataTable() : table; } but it calls only GetHashCode() and doesn't call Equals()

  • How to throw a SqlException(need for mocking)

    - by chobo2
    Hi I am trying to test some exceptions in my project and one of the Exceptions I catch is SQlException. Now It seems that you can't go new SqlException() so I am not sure how I can throw a exception especially without somehow calling the database(and since it is unit tests it is usually advised not to call the database since it is slow). So I am using nunit and moq so I am not sure how to fake this. Edit Based on the answers they seem to all be based on ado.net I am using linq to sql. So that stuff is like behind the scenes. Edit @ Matt Hamilton System.ArgumentException : Type to mock must be an interface or an abstract or non-sealed class. at Moq.Mock`1.CheckParameters() at Moq.Mock`1..ctor(MockBehavior behavior, Object[] args) at Moq.Mock`1..ctor(MockBehavior behavior) at Moq.Mock`1..ctor() Posts to the first line when it tries to mockup var ex = new Mock<System.Data.SqlClient.SqlException>(); ex.SetupGet(e => e.Message).Returns("Exception message");

  • Automapper use in a MVVM application

    - by Echiban
    I am building a MVVM application. The model / entity (I am using NHibernate) is already done, and I am thinking of using AutoMapper to map between the ViewModel and Model. However this clause scares the jebus out of me: (from http://www.lostechies.com/blogs/jimmy_bogard/archive/2009/01/22/automapper-the-object-object-mapper.aspx) Blockquote AutoMapper enforces that for each type map (source/destination pair), all of the properties on the destination type are matched up with something on the source type To me, the logical choice is to map from model to viewmodel, (and I'll let viewmodel manually assign to model), but the quote basically kills the idea since the viewmodel will definitely have properties that don't exist on the model. How have you been using Automapper in a MVVM app? Please help!

  • WiX major upgrade refuses to replace existing file!

    - by Joshua
    Hello! I have inherited this project with a WiX installer, and am required to make this version usefully upgrade the previous one! My problem comes in replacing the database files with new versions. No, the problem is not that they are locked, I can replace them manually, and in fact now ONE of them is replaced, while the other is not. Please, please tell me what I'm doing wrong here. I've tried several other solutions (including registry keys as KeyPath instead of CompanionFile) but nothing is quite working.

The entire log file from running the upgrade is located at: http://pastebin.com/ppjhq6Wi THANK YOU! Joshua

    I've got several div id's, each containing a different client. I want to be able to click the delete button and using ajax and jquery delete the specific div from the database. I'm getting success in AJAX but it's not deleting anything from the DB. And then obviously, upon deletion, I would like the container to reload dynamically. help!!! function DeleteClient(){ var yes = confirm("Whoa there chief! Do you really want to DELETE this client?"); if (yes == 1) { dataToLoad = 'clientID=' + clientID + '&deleteclient=yes', $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, success: function(html) { alert('Client' + clientID + ' should have been deleted from the database.'); $('#clientscontainer').html(html); }, error: function() { alert('error'); }});}; };

    What is the best way to go about this in C#? string propPath = "ShippingInfo.Address.Street"; I'll have a property path like the one above read from a mapping file. I need to be able to ask the Order object what the value of the code below will be. this.ShippingInfo.Address.Street Balancing performance with elegance. All object graph relationships should be one-to-one. Part 2: how hard would it be to add in the capability for it to grab the first one if its a List< or something like it.

  • VB.NET DownloadDataAsync:

    - by Brett
    Hi everybody, I am having the worst trouble getting around a bug, and am hoping that I can get some advice on this site. In short, I am trying to make an asynchronous web service call from my VB.NET application. But my "client_DownloadDataCompleted" callback is NEVER being called when the download is complete. Here is my complete code: Public Sub BeginAsyncDownload(ByVal Url As String) Dim waiter As System.Threading.AutoResetEvent = New System.Threading.AutoResetEvent(False) Dim client As WebClient = New WebClient() 'client_DownloadDataCompleted method gets called when the download completes. AddHandler client.DownloadDataCompleted, AddressOf client_DownloadDataCompleted Dim uri As Uri = New Uri(Url) Downloading = True 'Class variable defined elsewhere client.DownloadDataAsync(uri, waiter) End Sub Private Sub client_DownloadDataCompleted(ByVal sender As Object, ByVal e As AsyncCompletedEventArgs) MessageBox.Show("Download Completed") Downloading = False Debug.Print("Downloaded") End Sub Again, the client_DownloadDataCompleted method is never being called. I have also tried using the method: Private Sub client_DownloadDataCompleted(ByVal sender As Object, ByVal e As DownloadDataCompletedEventArgs) With no luck. What I really need is that "Downloading" variable to be switched off when the download is complete. Thanks in advance! Brett

  • App.config connection string Protection error

    - by MikeScott8
    I am running into an issue I had before; can't find my reference on how to solve it. Here is the issue. We encrypt the connection strings section in the app.config for our client application using code below: config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) If config.ConnectionStrings.SectionInformation.IsProtected = False Then config.ConnectionStrings.SectionInformation.ProtectSection(Nothing) ' We must save the changes to the configuration file.' config.Save(ConfigurationSaveMode.Modified, True) End If The issue is we had a salesperson leave. The old laptop is going to a new salesperson and under the new user's login, when it tries to to do this we get an error. The error is: Unhandled Exception: System.Configuration.ConfigurationErrorsException: An error occurred executing the configuration section handler for connectionStrings. ---> System.Configuration.ConfigurationErrorsException: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider'.

  • Differences & Similarities Between Programming Paradigms

    - by DaveDev
    Hi Guys I've been working as a developer for the past 4 years, with the 4 years previous to that studying software development in college. In my 4 years in the industry I've done some work in VB6 (which was a joke), but most of it has been in C#/ASP.NET. During this time, I've moved from an "object-aware" procedural paradigm to an object-oriented paradigm. Lately I've been curious about other programming paradigms out there, so I thought I'd ask other developers their opinions on the similarities & differences between these paradigms, specifically to OOP? In OOP, I find that there's a strong focus on the relationships and logical interactions between concepts. What are the mind frames you have to be in for the other paradigms? Thanks Dave

  • How do I use the gravity vector to correctly transform scene for augmented reality?

    - by gpdawson
    I'm trying figure out how to get an OpenGL specified object to be displayed correctly according to the device orientation (ie. according to the gravity vector from the accelerometer, and heading from compass). The GLGravity sample project has an example which is almost like this (despite ignoring heading), but it has some glitches. For example, the teapot jumps 180deg as the device viewing angle crosses the horizon, and it also rotates spuriously if you tilt the device from portrait into landscape. This is fine for the context of this app, as it just shows off an object and it doesn't matter that it does these things. But it means that the code just doesn't work when you attempt to emulate real life viewing of an OpenGL object according to the device's orientation. What happens is that it almost works, but the heading rotation you apply from the compass gets "corrupted" by the spurious additional rotations seen in the GLGravity example project. Can anyone provide sample code that shows how to adjust correctly for the device orientation (ie. gravity vector), or to fix the GLGravity example so that it doesn't include spurious heading changes? //Clear matrix to be used to rotate from the current referential to one based on the gravity vector bzero(matrix, sizeof(matrix)); matrix[3][3] = 1.0; //Setup first matrix column as gravity vector matrix[0][0] = accel[0] / length; matrix[0][1] = accel[1] / length; matrix[0][2] = accel[2] / length; //Setup second matrix column as an arbitrary vector in the plane perpendicular to the gravity vector {Gx, Gy, Gz} defined by by the equation "Gx * x + Gy * y + Gz * z = 0" in which we arbitrarily set x=0 and y=1 matrix[1][0] = 0.0; matrix[1][1] = 1.0; matrix[1][2] = -accel[1] / accel[2]; length = sqrtf(matrix[1][0] * matrix[1][0] + matrix[1][1] * matrix[1][1] + matrix[1][2] * matrix[1][2]); matrix[1][0] /= length; matrix[1][1] /= length; matrix[1][2] /= length; //Setup third matrix column as the cross product of the first two matrix[2][0] = matrix[0][1] * matrix[1][2] - matrix[0][2] * matrix[1][1]; matrix[2][1] = matrix[1][0] * matrix[0][2] - matrix[1][2] * matrix[0][0]; matrix[2][2] = matrix[0][0] * matrix[1][1] - matrix[0][1] * matrix[1][0]; //Finally load matrix glMultMatrixf((GLfloat*)matrix);

  • Python script repeated auto start up.

    - by Ali
    I am designing a python web app, where people can have an email sent to them on a particular day. So a user puts in his emai and date in a form and it gets stored in my database. My script would then search through the database looking for all records of todays date, retrive the email, sends them out and deletes the entry from the table. Is it possible to have a setup, where the script starts up automatically at a give time, say 1 pm everyday, sends out the email and then quits? If I have a continuously running script, i might go over the CPU limit of my shared web hosting. Or is the effect negligible? Ali

  • Wix XmlFile is keeping SqlDatabase from creating databases

    - by Grandpappy
    I've got a Wix project made up of several fragments. One of those fragments has the database components, another has a component that manipulates xml files. When I include the XmlFile element to manipulate a file, the databases defined by the SqlDatabase do not get created. If I comment out the XmlFile, then the databases do get created. Here are the two wix files with fragments that are being used: Database: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension"> <Fragment> <DirectoryRef Id="TARGETDIR"> <Component Id="Database1Creation" Guid="GUID_HERE"> <sql:SqlDatabase Id="Database1" Server="[DATABASE_SERVER]" Database="[DATABASE_NAME]" CreateOnInstall="yes" ConfirmOverwrite="no" DropOnUninstall="yes"> </sql:SqlDatabase> </Component> </DirectoryRef> </Fragment> </Wix> Xml Manipulation: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLDIR" Name="MyDirectory"> <Component Id="ServiceExecutables" Guid="GUID_HERE"> <File Id="File1" Name="File1.xml" Source="Source/File1.xml" /> <util:XmlFile Id="UpdateFile1" File="[INSTALLDIR]File1.xml" Action="setValue" ElementPath="//SomeContainer/SomeElement" Value="[SOME_VALUE]" /> </Component> </Directory> </Directory> </Directory> </Fragment> </Wix> There are other things that are also installed, but they don't appear to have any influence on the issue (I've removed everything else and tested the install). When looking at the install logs when using XmlFile and when not, they are almost exact copies of each other, except that the SqlDatabase calls would be completely missing, and the XmlFile calls would be in their place. Is there a known bug here? Or am I doing something I shouldn't be? This isn't a killer for our app, since I can move the things I'm putting in the xml file into the registry, but I'd rather not do that. I am using Wix 3.5.

  • new[n] and delete every location with delete instead the whole chunk with delete[]

    - by pmr
    Is this valid C++ (e.g. not invoking UB) and does it achieve what I want without leaking memory? valgrinds complains about mismatching free and delete but says "no leaks are possible" in the end. int main() { int* a = new int[5]; for(int i = 0; i < 5; ++i) a[i] = i; for(int i = 0; i < 5; ++i) delete &a[i]; } The reason I'm asking: I have a class that uses boost::intrusive::list and I new every object that is added to that list. Sometimes I know how many objects I want to add to the list and was thinking about using new[] to allocate a chunk and still be able to delete every object on its own with the Disposer-style of boost::intrusive.

  • C# System.Data.SQLite Designer Code

    - by Nathan
    I've been messing around with the SQLite Designer in Visual Studio 2008 and I have noticed that when I use the generated Insert/Update statements they run extremely slow. Example: I have a data table with four columns and 5700 rows it took ~5 mins to insert the data into the database table However, I wrote my own database connection and insert methods using parameters and a single transaction and the same 5700 rows were inserted in under 1 second. Why is the generated code so slow and what is benefit to even using it? Thanks. Nathan

  • Landscape orientation for UITabBarController?

    - by gingersnap
    The UITabBarController does not allow landscape orientation. So I used a subclass of UITabBarContoller (called RotatingTabBarController). Its sole purpose it to allow rotation by returning YES to shouldAutorotateToInterfaceOrientation call. The problem is that when you rotate the iPhone in simulator it gives the following malloc error. malloc: *** error for object 0x3888000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I am using 3.0 SDK with Xcode 3.2 on Snow Leopard. I set a breakpoint in malloc_error_break but I can not trace it back to my code. Is there something I can do to make this error go away? Here is the RotatingTabBarController class: #import <UIKit/UIKit.h> @interface RotatingTabBarController : UITabBarController { } @end @implementation RotatingTabBarController -(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation { return YES; } @end Update: I tried the same with a category. But it gives the same malloc error. // UITabBarController+Rotation.h @interface UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation; @end // UITabBarController+Rotation.m #import "UITabBarController+Rotation.h" @implementation UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end Backtrace [Session started at 2009-09-05 12:13:19 -0400.] Untitled(992,0xa06d9500) malloc: *** error for object 0x2024000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Untitled(992,0xa06d9500) malloc: *** error for object 0x2014000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug [Session started at 2009-09-05 12:13:27 -0400.] GNU gdb 6.3.50-20050815 (Apple version gdb-1344) (Fri Jul 3 01:19:56 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • Git over SSH Server in Windows, cannot find shared libraries.

    - by Roy Marco Aruta
    I was to setup an SSH Server to Host my Git Repository to my local area network. I followed this tutorial by TimDavis hoping that I would be able to make a secured Git Repository. I tested my connection using Putty and it was successful. My only problem was I cannot run "git" command in the console. Then I tried cloning my repository, and this was the error that outputed: /usr/bin/git-upload-pack.exe: error while loading shared libraries: libiconv2.dll: cannot open shared object file: No such file or directory Also when I ran "git" command in the Putty Bash that was connected to the SSH Server, this was the error I encountered: /usr/bin/git.exe: error while loading shared libraries: pthreadGC2.dll: cannot open shared object file: No such file or directory I seems that all my problem was about the missing libraries but I don't know how to solve it. I am using Windows 7 as an Operating System. Thanks

  • AJAX.dll is throwing error?

    - by Ramesh
    Hi all, I am using Ajax.dll in my web application.I need to refresh a page for maintaining a session more than one hour, So I created a ajax method that will be called for every 15 mins. Suddenly it throws an error System.NullReferenceException: Object reference not set to an instance of an object. at Ajax.AjaxRequestProcessor.Run() at Ajax.AjaxHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) I thought the error might be in Ajax dll. Can anyone please help me to get rid of the issue please.

  • heroku mongohq and mongoid Mongo::ConnectionFailure

    - by Ole Morten Amundsen
    I have added the mongoHQ addon for mongodb at heroku. It crashes with something like this. connect_to_master': failed to connect to any given host:port (Mongo::ConnectionFailure) The descriptions online (heroku mongohq) are more directed towards mongomapper, as I see it. I'm running ruby 1.9.1 and rails 3-beta with mongoid. My feeling says that there's something with ENV['MONGOHQ_URL'], which it says the MongoHQ addon sets, but I haven't set MONGOHQ_URL anywhere in my app. I guess the problem is in my mongoid.yml ? defaults: &defaults host: localhost development: <<: *defaults database: aliado_development test: <<: *defaults database: aliado_test # set these environment variables on your prod server production: <<: *defaults host: <%= ENV['MONGOID_HOST'] %> port: <%= ENV['MONGOID_PORT'] %> username: <%= ENV['MONGOID_USERNAME'] %> password: <%= ENV['MONGOID_PASSWORD'] %> database: <%= ENV['MONGOID_DATABASE'] %> It works fine locally, but fails at heroku, more stack trace: ==> crashlog.log <== Cannot write to outdated .bundle/environment.rb to update it /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/rack-1.1.0/lib/rack.rb:14: warning: already initialized constant VERSION /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongo-0.20.1/lib/mongo/connection.rb:435:in `connect_to_master': failed to connect to any given host:port (Mongo::ConnectionFailure) from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongo-0.20.1/lib/mongo/connection.rb:112:in `initialize' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4 /lib/mongoid/railtie.rb:32:in `new' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid/railtie.rb:32:in `block (2 levels) in <class:Railtie>' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid.rb:110:in `configure' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/mongoid-2.0.0.beta4/lib/mongoid/railtie.rb:21:in `block in <class:Railtie>' from /disk1/home/slugs/176479_b14df52_b875/mnt/.bundle/gems/gems/railties-3.0.0.beta3/lib/rails/initializable.rb:25:in `instance_exec' ..... It all works locally, both tests and app. I'm out of ideas... Any suggestions? PS: Somebody with high repu mind create the tag 'mongohq'?

  • Asp.net Mvc 2: Repository, Paging, and Filtering how to?

    - by Dr. Zim
    It makes sense to pass a filter object to the repository so it can limit what records return: var myFilterObject = myFilterFactory.GetBlank(); myFilterObject.AddFilter( new Filter { "transmission", "eq", "Automatic"} ); var myCars = myRepository.GetCars(myfilterObject); Key question: how would you implement paging and where? Any links on how to return a LazyList from a Repository as it would apply here? Would this be part of the filter object? Something like: myFilterObject.AddFilter( new Filter { "StartAtRecord", "eq", "45"} ); myFilterObject.AddFilter( new Filter { "GetQuantity", "eq", "15"} ); var myCars = myRepository.GetCars(myfilterObject); I assume the repository must implement filtering, otherwise you would get all records.

  • WCF Data Services consuming data from EF based repository

    - by John Kattenhorn
    We have an existing repository which is based on EF4 / POCO and is working well. We want to add a service layer using WCF Data Services and looking for some best practice advice. So far we have developed a class which has a IQueryable property and the getter triggers the repository 'get all users' method. The problem so far have been two-fold: 1) It required us to decorate the ID field of the poco object to tell data service what field was the id. This now means that our POCO object is not 'pure'. 2) It cannot figure out the relationships between the objects (which is obvious i guess). I've now stopped this approach and i'm thinking that maybe we should expose the OBjectContext from the repository and use more 'automatic' functionality of EF. Has anybody got any advice or examples of using the repository pattern with WCF Data Services ?
