  • iphone cannot rotate views in TabBar controller

    - by Luc
    Hello, I am working on an application that consists of a TabBar controller. Within on of its tab, I have a subclass of UITableViewController, within this list I have a Core-plot graph in the first cell and some other data in the 4 following cells. When I return YES in the shouldAutorotateToInterfaceOrientation method, I would expect the autoresizing of the list view to happen, but... nothing. When I add some log in the willRotateToInterfaceOrientation method, they are not displayed. Is there something I missed ? Thanks a lot, Luc // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations //return (interfaceOrientation == UIInterfaceOrientationPortrait); NSLog(@"Orientation"); return YES; } - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; NSLog(@"Rotating"); if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { NSLog(@"view land:%@", self.view); } if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { NSLog(@"view portrait:%@", self.view); } }

  • Creating a castable entity class wrapper

    - by Tony
    Hi I need to have a wrapper class that exposes some properties of my entity class called ProfileEntity. I tried doing it by deriving from this entity and then creating properties that return specific entity properties, but it says I cannot cast from ProfileEntity to ProfileEntityWrapper. When I try to put the return values of a method that returns a 'ProfileEntity' into the wrapper I get the above error. How do I create such a wrapper class that is castable? Example class ProfileEntityWrapper : ProfileEntity { public string Name { get { return this.ProfileEntityName; } } public class Someclass { public ProfileEntity SomeMethod() { return ProfileEntity; // example of method returning this object } } public class SomeOtherlClass { SomeClass sc = new SomeClass(); public void DoSomething() { ProfileEntityWrapper ew = (ProfileEntityWrapper)sc.SomeMethod(); // Cannot do this cast!!! } }

  • Custom UITableViewCell not properly hiding views

    - by adamweeks
    I am using apple's custom table view cell code and modifying the drawRect code within the cell's view to look like I want it to. I've changed it to have some UILabels as well as a UIProgressView. If the data the cell is being built on doesn't have a certain field, I want the UIProgressView to be hidden. This works for a little while, but when a cell gets requeued, the progress view will start displaying again, even when I set it to hidden = YES. I've tried just not creating the ProgressView unless the data was there and that didn't work either. I thought the answer was in the [self setNeedsDisplay] but that doesn't seem to help. Here is the code for the progressview from drawRect that continues to be displayed: UIProgressView *c1Progress = [[UIProgressView alloc]initWithFrame:CGRectMake(20.0, 70.0, 280.0, 12.0)]; float iProgress = (value / target); c1Progress.progress = iProgress; if (!dataExists) { c1Progress.hidden = YES; } [self addSubview:criteria1Progress]; [c1Progress release];

  • use multiple views in an application

    - by Gaurav Arora
    Hi All, I am new to Iphone programming. So please don't mind if I ask some basic questions. :mad: I want to develop an application where the landing screen will be a login screen and after login application should display a new screen with the list of available categories. And on selecting any category a new screen should appear with the information related to the selected category. Basically I want to display different screens in the applications and my confusion is how can I make different screens with one .xib file? or should I use different .xib files for each screen. If I use different .xib files for each screen then how should I navigate to different screens. Please help in solving this confusion. Thanks in advance Gaurav

  • Catching an exception class within a template

    - by Todd Bauer
    I'm having a problem using the exception class Overflow() for a Stack template I'm creating. If I define the class regularly there is no problem. If I define the class as a template, I cannot make my call to catch() work properly. I have a feeling it's simply syntax, but I can't figure it out for the life of me. #include<iostream> #include<exception> using namespace std; template <class T> class Stack { private: T *stackArray; int size; int top; public: Stack(int size) { this->size = size; stackArray = new T[size]; top = 0; } ~Stack() { delete[] stackArray; } void push(T value) { if (isFull()) throw Overflow(); stackArray[top] = value; top++; } bool isFull() { if (top == size) return true; else return false; } class Overflow {}; }; int main() { try { Stack<double> Stack(5); Stack.push( 5.0); Stack.push(10.1); Stack.push(15.2); Stack.push(20.3); Stack.push(25.4); Stack.push(30.5); } catch (Stack::Overflow) { cout << "ERROR! The stack is full.\n"; } return 0; } The problem is in the catch (Stack::Overflow) statement. As I said, if the class is not a template, this works just fine. However, once I define it as a template, this ceases to work. I've tried all sorts of syntaxes, but I always get one of two sets of error messages from the compiler. If I use catch(Stack::Overflow): ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2316: 'Stack::Overflow' : cannot be caught as the destructor and/or copy constructor are inaccessible EDIT: I meant If I use catch(Stack<double>::Overflow) or any variety thereof: ch18pr01.cpp(89) : error C2061: syntax error : identifier 'Stack' ch18pr01.cpp(89) : error C2310: catch handlers must specify one type ch18pr01.cpp(95) : error C2317: 'try' block starting on line '75' has no catch handlers I simply can not figure this out. Does anyone have any idea?

  • Mock static method Activator.CreateInstance to return a mock of another class

    - by Jeep87c
    I have this factory class and I want to test it correctly. Let's say I have an abstract class which have many child (inheritance). As you can see in my Factory class the method BuildChild, I want to be able to create an instance of a child class at Runtime. I must be able to create this instance during Runtime because the type won't be know before runtime. And, I can NOT use Unity for this project (if so, I would not ask how to achieve this). Here's my Factory class that I want to test: public class Factory { public AnAbstractClass BuildChild(Type childType, object parameter) { AnAbstractClass child = (AnAbstractClass) Activator.CreateInstance(childType); child.Initialize(parameter); return child; } } To test this, I want to find a way to Mock Activator.CreateInstance to return my own mocked object of a child class. How can I achieve this? Or maybe if you have a better way to do this without using Activator.CreateInstance (and Unity), I'm opened to it if it's easier to test and mock! I'm currently using Moq to create my mocks but since Activator.CreateInstance is a static method from a static class, I can't figure out how to do this (I already know that Moq can only create mock instances of objects). I took a look at Fakes from Microsoft but without success (I had some difficulties to understand how it works and to find some well explained examples). Please help me! EDIT: I need to mock Activator.CreateInstance because I want to force this method to return another mocked object. The correct thing I want is only to stub this method (not to mock it). So when I test BuildChild like this: [TestMethod] public void TestBuildChild() { var mockChildClass = new Mock(AChildClass); // TODO: Stub/Mock Activator.CreateInstance to return mockChildClass when called with "type" and "parameter" as follow. var type = typeof(AChildClass); var parameter = "A parameter"; var child = this._factory.BuildChild(type, parameters); } Activator.CreateInstance called with type and parameter will return my mocked object instead of creating a new instance of the real child class (not yet implemented).

  • One of my apache processes is huge - how can I find out why?

    - by Malcolm Box
    I'm running Apache 2.2.12 with mod_wsgi, hosting a Django site. Most of the apache child processes weigh in at about 125MB RSS, but occasionally I see one child balloon to 1GB RSS. At this point there's usually 1 huge process (1GB), a couple of large ones (500MB) and the rest are still ~125MB. These are the mod_wsgi daemon processes. I've tried using memory leak tracing in Python to see if it's the Django code, and I see no leaks. Looking in the logs doesn't show any particularly strange requests. I'm stumped on how to figure out what's causing this - any ideas? Also, any workaround ways to kill the large apache process when it gets too big, without bringing apache down? Some more details: Not using mod_php Using pre-fork

  • iPhone web views - detecting short phone numbers

    - by Pedro
    G'day All Most Australian phone numbers are 10 digits with the 1st 2 optional if they're a local area code. For those setting... viewer.dataDetectorTypes = UIDataDetectorTypePhoneNumber; on a web view works. We also have a range of 6 digit phone numbers (usually written xxx xxx or xx xxxx) which aren't being detected in my app. Is there a way to detect those phone numbers as well? Cheers & TIA, Pedro :)

  • How to access "overridden" inner class in Scala?

    - by doom2.wad
    I have two traits, one extending the other, each with an inner class, one extending the other, with the same names: trait A { class X { def x() = doSomething() } } trait B extends A { class X extends super.X { override def x() = doSomethingElse() } } class C extends B { val x = new X() // here B.X is instantiated val y = new A.X() // does not compile val z = new A.this.X() // does not compile } How do I access A.X class in the C class's body? Renaming B.X not to hide A.X is not a preferred way. To make things a bit complicated, in the situation I have encountered this problem the traits have type parameters (not shown in this example).

  • Drupal using views with CCK custom fields

    - by jackbot
    I've got a Drupal site which uses a custom field for a certain type of node (person_id) which corresponds to a particular user. I want to create a view so that when logged in, a user can see a list of nodes 'tagged' with their person_id. I've got the view working fine, with a url of my-library/username but replacing username with a different username shows a list of all nodes tagged with that user. What I want to do is stop users changing the URL and seeing other users' tagged nodes. How can I do this? Is there somewhere where I can dictate that the only valid argument for this page is the one that corresponds with the current logged in user's username?

  • Is there any way to isolate the python2.7 , mod_wsgi installation from main environment

    - by user31
    I have many local virtual machines for building the django websites. I find it very hard to configure all the machines with mod_wsgi , python and all that installation issues. Is there any way that i can install even python 2.7 , mod_wsgi etc and all that inside the virtual environment folder so that i can just copy paste that folder in my live server and i don't need to mess with mos_wsgi , python 2.7 and other issues. Is it possible or even any close variation of that so that puting the site to live servers is very easy and everything which is needed by site should be included locally I also face many problems when i need to move the django sites across servers

  • Internet Explorer percent based layout issue

    - by Tom
    Heya, My goal is to make a layout that is 200% width and height, with four containers of equal height and width (100% each), using no javascript as the bear minimum (or preferably no hacks). Right now I am using HTML5, and CSS display:table. It works fine in Safari 4, Firefox 3.5, and Chrome 5. I haven't tested it yet on older versions. Nonetheless, in IE7 and IE8 this layout fails completely. (I do use the Javascript HTML5 enabling script /cc../, so it should not be the use of new HTML5 tags) Here is what I have: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta charset="UTF-8" /> <title>IE issue with layout</title> <style type="text/css" media="all"> /* styles */ @import url("reset.css"); /* Generall CSS */ .table { display:table; } .row { display:table-row; } .cell { display:table-cell; } /* Specific CSS */ html, body { //overflow:hidden; I later intend to limit the viewport } section#body { position:absolute; width:200%; height:200%; overflow:hidden; } section#body .row { width:200%; height:50%; overflow:hidden; } section#body .row .cell { width:50%; overflow:hidden; } section#body .row .cell section { display:block; width:100%; height:100%; overflow:hidden; } section#body #stage0 section header { text-align:center; height:20%; display:block; } section#body #stage0 section footer { display:block; height:80%; } </style> </head> <body> <section id="body" class="table"> <section class="row"> <section id="stage0" class="cell"> <section> <header> <form> <input type="text" name="q" /> <input type="submit" value="Search" /> </form> </header> <footer> <table id="scrollers"> </table> </footer> </section> </section> <section id="stage1" class="cell"> <section> content </section> </section> </section> <section class="row"> <section id="stage2" class="cell"> <section> content </section> </section> <section id="stage3" class="cell"> <section> content </section> </section> </section> </section> </body> </html> You can see it live here: http://www.tombarrasso.com/ie-issue/

  • Constructing human readable sentences based on a survey

    - by Joshua
    The following is a survey given to course attendees to assess an instructor at the end of the course. Communication Skills 1. The instructor communicated course material clearly and accurately. Yes No 2. The instructor explained course objectives and learning outcomes. Yes No 3. In the event of not understanding course materials the instructor was available outside of class. Yes No 4. Was instructor feedback and grading process clear and helpful? Yes No 5. Do you feel that your oral and written skills have improved while in this course? Yes No We would like to summarize each attendees selection based on the choices chosen by him. If the provided answers were [No, No, Yes, Yes, Yes]. Then we would summarize this as "The instructor was not able to summarize course objectives and learning outcomes clearly, but was available for usually helpful outside of class. The instructor feedback and grading process was clear and helpful and I feel that my oral and written skills have improved because of this course. Based on the selections chosen by the attendee the summary would be quite different. This leads to many answers based on the choices selected and the number of such questions in the survey. The questions are usually provided by the training organization. How do you come up with a generic solution so that this can be effectively translated into a human readable form. I am looking for tools or libraries (java based), suggestions which will help me create such human readable output. I would like to hide the complexity from the end users as much as possible.

  • Creating Membership Tables, SPROCs, Views in Attached DB

    - by azamsharp
    I have AdventureWorks database mdf file in my VS 2010 project. Is there anyway I can create Membership tables inside my AdventureWorks database. I know I can detach the database attach in SQL SERVER 2008. Create the tables and then detach. But I don't have SQL SERVER 2008 and I want to see if this can be done using command line tool. I tried this but no use: aspnet_regsql.exe -d AdventureWorks.mdf -A mr -E -S .\SQLEXPRESS Update: If I right click and see the properties of the AdventureWorks.mdf database then it shows the name as "C4BE6C8DA139A060D14925377A7E63D0_64A_10\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKS\APP_DATA\ADVENTUREWORKS.MDF" This is interesting!

  • First class language in Visual Studio 2010 using F#

    - by Aamir Hasan
     F# is a strongly-typed language like C#.It is light weight syntax just like Python.It give you math-like feel. let data = (1,2,3)   let rotations (x, y, z) =     [ (x, y, z);       (z, x, y);       (y, z, x) ]   let derivative f x =     let p1 = f (x - 0.05)     let p2 = f (x + 0.05)     (p2 - p1) / 0.1   let f x = 2.0*x*x - 6.0*x + 3.0   let df = derivative f   System.Console.WriteLine("The derivative of f at x=4 is {0}", df 4.0)   This program will print: “The derivative of f at x=4 is 10”That’s a quick look at just a few of the exciting features of F#.  For more on F#, visit the F# Development Center on MSDN.

  • c# class naming standards/guidelines

    - by Ben
    Over the years I've used various naming conventions for services in my applications for example: [ClassName]Service [ClassName]Manager [ClassName]Factory [ClassName]Provider [ClassName]Helper I generally only use the "Helper" suffix for utility classes that have no external dependencies. However I find that there is a bit of a cross-over between the others, and wondered if there was any recommendations/standards/guidelines on what to use and when?

  • Static Class Variables in Dynamic Library and Main Program

    - by Paul
    I am working on a project that has a class 'A' that contains a static stl container class. This class is included in both my main program and a .so file. The class uses the default(implicit, not declared) constructor/destructor. The main program loads the .so file using dlopen() and in its destructor, calls dlclose(). The program crashes after main exits when glibc calls the destructor for the static class member variable. The problem appears to be that when dlclose() is called, the destructor for the static variable is called, then when main exits() glibc also calls the destructor, resulting in a double free. I have 2 questions, namely: 1) In this particular case, why are there not two copies of the static variable(yes i know that sounds somewhat ridiculous, but since both the main program and .so file have a separately compiled 'A', shouldn't they each have one?) 2) Is there any way to resolve this issue without re-writing class 'A' to not contain static member variables?

  • MVVM Light - master / child views and dependency properties

    - by Carl Dickinson
    I'm getting an odd problem when implementing a master / child view and custom dependency properties. Within my master view I'm binding the view model declaratively in the XAML as follows: DataContext="{Binding MainViewModelProperty, Source={StaticResource Locator}}" and my MainViewModel is exposing an observable collection which I'm binding to an ItemsControl as follows: <ItemsControl ItemsSource="{Binding Lists}" Height="490" Canvas.Top="10" Width="70"> <ItemsControl.ItemTemplate> <DataTemplate> <Canvas> <local:TaskListControl Canvas.Left="{Binding ListLeft}" Canvas.Top="{Binding ListTop}" Width="{Binding ListWidth}" Height="{Binding ListHeight}" ListDetails="{Binding}"/> </Canvas> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> TaskListControl in turn declares and bind to it's ViewModel and I've also defined a dependency property for the ListDetails property. The ListDetails property is not being set and if I remove the declarative reference to it's viewmodel the dependency property's callback does get fired. Is there a conflict with declaratively binding to viewmodels and definig dependency properties? I really like MVVM Light's blendability and want to perserve with this problem so any help would be apprectiated. If you'd like to receive the source for my project then please ask

  • Rendering PDFs from a database inside MVC views?

    - by Mohammad Sepahvand
    I was wondering if it's possible to do this without using 3rd party compnents in MVC 3. (I am open to free components though.) There are a couple of links out there but they seem to be mostly concerned with reporting and other code samples that do claim to do this sort of thing don't seem to compile. I'm not having any trouble saving and retrieving the PDFs to and from my database, but when I return the PDF as a File or a FileStreamResult the user is prompted with a download. A more desirable approach would be to actually render the PDFs inside the browser. I've had a look at iTextSHarp, it does the job to an extent, but it's not a complete solution. For example it will display the PDF inside the view if and only if the client has Adobe Reader installed, otherwise it prompts for a download. So technically, I'm mostly looking for a PDF viewer. Any ideas?

  • C# Class Design Question

    - by Soo
    This is a super newbie question, I've been programming for a while, but am just learning OOP. I have a class that works with user input via the C# console. There are different methods in this class to gather different input sets. I have another class that takes these input sets and puts them in a database. What is the best way to pass the input from my input class to my database insert class? My guess would be: Array1[] = inputClass.GetParameterSet1(); DatabaseInsertClass.InsertIntoDatabase1(Array1[]); Is there anything wrong with this or is there a better way to do this? Should I even have two classes (The database class could also take the user input)?
