  • Non-member functions in Objective-C

    - by Jellyfingers McSlimedessert
    I want to write a standalone function in Objective-C; so essentially a C-style function, with Objective-C calls in it. For example: NSString* someFunc() { NSString* str = [[NSString alloc] init]; return str; } I declare the function in a header file, and define in it a .m file. However, the function doesn't appear to be compiled in, as the linker complains about the missing symbol. I thought that maybe I should put it in a C file, but then of course it spat at me for writing Objective-C Nonsense in BASI... C. What do?

  • Is writing eSQL database agnostic?

    - by Robert Koritnik
    Using EF we can use LINQ to read data which is rather simple (especialy using fluent calls), but we have less control unless we write eSQL on our own. Is writing eSQL database actually data store independant code? So if we decide to change data store, can the same statements still be used? Is writing eSQL strings in your code pose any serious security threats similar to writing TSQL statements in plain strings? So we moved to SPs. Could we still mode eSQL scripts outside of code as well and use some other technique to make them a bit more secure?

  • Is there an "opposite" to the null coalescing operator? (…in any language?)

    - by Jay
    null coalescing translates roughly to return x, unless it is null, in which case return y I often need return null if x is null, otherwise return x.y I can use return x == null ? null : x.y; Not bad, but that null in the middle always bothers me -- it seems superfluous. I'd prefer something like return x :: x.y;, where what follows the :: is evaluated only if what precedes it is not null. I see this as almost an opposite to null coalescence, kind of mixed in with a terse, inline null-check, but I'm [almost] certain that there is no such operator in C#. Are there other languages that have such an operator? If so, what is it called? (I know that I can write a method for it in C#; I use return NullOrValue.of(x, () => x.y);, but if you have anything better, I'd like to see that too.)

  • Testing injected dependencies into your struts2 actions

    - by Barry
    Hi, I am wondering how others might have accomplished this. I found in the Spring documentation @required which I attempted to use in a 'test' but got this stmt INFO XmlConfigurationProvider:380 - Unable to verify action class [xxx] exists at initialization I have found another way in spring to do this is to write custom init methods and declare those on the bean but it almost seems like this is a strange thing to do to a struts2 action. In my application I inject through spring different web services (via setter injection) into different actions. I want to ensure on startup these are not null and set.

  • UITextView text disappear

    - by user153412
    Hi, i create an uitextview dynamically then i write my text into it. Sometime, when i create the uitextview, the cursor disappear and i see no text in it. If i run the application again, i can see the text inside the textview that i've created before. I've tried to set the cursor position to zero or scroll the text to the top but it doesn't work... Any suggestion? Here is a screen capture. You can see the gray uitextview, the keyboard (the textview is the firstresponder) but no cursor or text. http://yfrog.com/hqschermata20100325a11213p PS: i'm sorry for my bad english.

  • Google App Engine (python): TemplateSyntaxError: 'for' statements with five words should end in 'rev

    - by Phil
    This is using the web app framework, not Django. The following template code is giving me an TemplateSyntaxError: 'for' statements with five words should end in 'reversed' error when I try to render a dictionary. I don't understand what's causing this error. Could somebody shed some light on it for me? {% for code, name in charts.items %} <option value="{{code}}">{{name}}</option> {% endfor %} I'm rendering it using the following: class GenerateChart(basewebview): def get(self): values = {"datepicker":True} values["charts"] = {"p3": "3D Pie Chart", "p": "Segmented Pied Chart"} self.render_page("generatechart.html", values) class basewebview(webapp.RequestHandler): ''' Base class for all webapp.RequestHandler type classes ''' def render_page(self, filename, template_values=dict()): filename = "%s/%s" % (_template_dir, filename) path = os.path.join(os.path.dirname(__file__), filename) self.response.out.write(template.render(path, template_values))

  • System.Overflow Exception - int32 is too large or small

    - by LonnieBest
    I need a little advice. I've got windows service that runs at night. In my development environment, it runs without exception, but when I running it "installed on other machines", when I come in the morning, I'm welcomed with a System.Overflow exception that says that I've set an int32 to value that is too large or small. I've carefully combed the service's c# code, and I have try/catch statements around everything, that should catch any error and write it to a log without completely stopping my service with this overflow exception. But still, it occurs and stops the service. I'd appreciate any conceptual advice on how to pin point what's causing an error such as this.

  • Iphone build error - literal-pointer symbol(s) not found

    - by Nick
    Sorry I imagine I'm missing something basic here. Before I write up a bunch of details on the specifics of the class I'd appreciate a nudge or smack on the head about the meaning of this build error. I have a subclass of NSObject SiteAnnotation that should be conforming to the MKAnnotation protocol. It is #imported in the ViewController in question When I try to alloc/init: SiteAnnotation *thisAnnotation = [[SiteAnnotation alloc] init]; This is the build error which occurs: Link /build/Debug-iphonesimulator/testbed.app/testbed ".objc_class_name_SiteAnnotation", referenced from: literal-pointer@__OBJC@__cls_refs@SiteAnnotation in MapViewController.o Symbol(s) not found collect2: ld returned 1 exit status Any tips appreciated.

  • Bug tracking/ticket systems? What is good?

    - by Earlz
    Hello, we are looking for a bug tracking software that is suitable for us developers and for our (non technical) end users. We our currently using FogBugz which is very amazing, except for it sucks for the end user support. It could be possible to write a portal/add in for it to do what we want, but it'd still be rather hackish to make FogBugz do something it wasn't designed for. What bug tracking systems out there would you guys recommend? We are looking for something relatively cheap(or free). We are a very small startup (less than 5 people) dealing with 50 or so end users. Any ideas? Also, we do not need extra features like wikis or discussion groups or anything like that. Basically just a way for our end users to submit bugs and support requests, and a way for the developers to keep track of bugs and features.

  • How to learn high-level Java web development concepts

    - by titaniumdecoy
    I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

  • Rich text editor for JSF 2

    - by Pradyumna
    Hi, I searched around for a basic WYSIWYG rich text editor that I can use in a JSF 2 (VDL) application, but found nothing satisfactory.. in the sense that: The editor is very extensive, and not configurable (like PrettyFaces) The editor doesn't work with VDL (like RichFaces) Multiple instances of the editor cannot be used on the same page (like Tomahawk t:htmlArea) I actually don't need all the fancy things like Fonts, Indenting/justification, undo/redo... just Bold, Italic, Lists and Hyperlinks would suffice. Do you know of something that works well in this scenario, as well as gives out XHTML compliant markup, and works well with partial page refreshes(f:ajax), or would you recommend that I write my own? Thank you! Pradyumna

  • Custom array sorting based on instance properties

    - by St. John Johnson
    I'm trying to perform a usort on an array inside an instance of a class. But the sort is dependent on the properties of said instance. Code (which doesn't work): class foo { private $array; private $key; private $dir; function sort() { usort($this->array, array("foo", "orderArray")); } function orderArray($a, $b) { return strcmp($a[$this->key], $b[$this->key]) * $this->dir; } } From the orderArray class, you can't access $key or $dir. The question is, how can I write this so I can?

  • Spring Security 3.0 and Active Directory LDAP: DOMAIN\user login

    - by Bernd Haug
    I would like to have users authenticate against an ActiveDirectory LDAP server using the DOMAIN\user.name syntax. I think that should be possible with SpringSec 3.0 since the docs mention an "alternative syntax" which I guess refers to the DOM\user syntax instead of a bind DN, but the docs don't elaborate further. Is there some way to configure Spring Sec 3 LDAP to use "the MS way" or do I have to write my own Authenticator implementation (against e.g. the java.naming.directory package, which I've tested to be able to use the MS syntax as its SECURITY_PRINCIPAL)?

  • C# Multithreading File IO (Reading)

    - by washtik
    We have a situation where our application needs to process a series of files and rather than perform this function synchronously, we would like to employ multi-threading to have the workload split amongst different threads. Each item of work is: 1. Open a file for read only 2. Process the data in the file 3. Write the processed data to a Dictionary We would like to perform each file's work on a new thread? Is this possible and should be we better to use the ThreadPool or spawn new threads keeping in mind that each item of "work" only takes 30ms however its possible that hundreds of files will need to be processed. Any ideas to make this more efficient is appreciated.

  • the carry flag issue!

    - by Zia ur Rahman
    Suppose AX =FFFE and BX=1234 now if we write cmp ax,bx (bx will be subtracted from ax and the approprite flages will be updated) now the binary representation of the numbers in ax and bx is given by AX = 1111 1111 1111 1110 BX= 0001 0010 0011 0100 As bx will be subtracted from ax so we have to negate bx (as Result= ax+(-bx)) so the negated bx (2's complement of bx ) is given by. BX= 1110 1101 1100 1100 Now we add both ax and bx (as subtraction is implemented by addition in computer) AX= 1111 1111 1111 1110 BX= 1110 1101 1100 1100 ------------------------------------ 1 1110 1101 1100 1010 Now as you can see the result is of 17 bits now the 17th bit should go into carry flage, but when i checked it the carry flag is 0 that is CF=0 why?

  • how to group by over anonymous type with vb.net linq to object

    - by smoothdeveloper
    I'm trying to write a linq to object query in vb.net, here is the c# version of what I'm trying to achieve (I'm running this in linqpad): void Main() { var items = GetArray( new {a="a",b="a",c=1} , new {a="a",b="a",c=2} , new {a="a",b="b",c=1} ); ( from i in items group i by new {i.a, i.b} into g let p = new{ k = g, v = g.Sum((i)=>i.c)} where p.v > 1 select p ).Dump(); } // because vb.net doesn't support anonymous type array initializer, it will ease the translation T[] GetArray<T>(params T[] values){ return values; } I'm having hard time with either the group by syntax which is not the same (vb require 'identifier = expression' at some places, as well as with the summing functor with 'expression required' ) Thanks so much for your help!

  • Why can't I download a whole image file with urllib2.urlopen()

    - by John Gann
    When I run the following code, it only seems to be downloading the first little bit of the file and then exiting. Occassionally, I will get a 10054 error, but usually it just exits without getting the whole file. My internet connection is crappy wireless, and I often get broken downloads on larger files in firefox, but my browser has no problem getting a 200k image file. I'm new to python, and programming in general, so I'm wondering what nuance I'm missing. import urllib2 xkcdpic=urllib2.urlopen("http://imgs.xkcd.com/comics/literally.png") xkcdpicfile=open("C:\\Documents and Settings\\John Gann\\Desktop\\xkcd.png","w") while 1: chunk=xkcdpic.read(4028) if chunk: print chunk xkcdpicfile.write(chunk) else: break

  • OpenCL or OpenGL – which one to use?

    - by Malte Schledjewski
    My Problem involves a black and white image with a black area in the middle. I never worked with OpenGL or OpenCL before so I do not know which one to chose. I want to put some white circles over the area and check at the end whether the whole image is white. I will try many combinations so I want to use the GPU because of its parallelism. Should I use OpenGL and create the circle as a texture and put it on top of the image or should I write some OpenCL kernels which work on the pixel/entries in the matrix?

  • Problem in Tabindex

    I have around 50-60 components and some of the fields are readonly. Now I want to set the tab index only for the fields that are read/write. Now the problem for me is, some of the components will be added according to the selection in my dropdown list box. Those components that are newly populated also contains some read only text boxes. The thing is, some of the options in the dropdown list may contain or may not contain components. So how could I Give the tabindex appropriately. eg : textbox1 : tabindex="1" textbox2 : tabindex="2" dropdown : tabindex="3" textbox for dropdown : tabindex="?" textbox : tabindex="?"

  • fourier transform to transpose key of a wav file

    - by tbischel
    I want to write an app to transpose the key a wav file plays in (for fun, I know there are apps that already do this)... my main understanding of how this might be accomplished is to 1) chop the audio file into very small blocks (say 1/10 a second) 2) run an FFT on each block 3) phase shift the frequency space up or down depending on what key I want 4) use an inverse FFT to return each block to the time domain 5) glue all the blocks together But now I'm wondering if the transformed blocks would no longer be continuous when I try to glue them back together. Are there ideas how I should do this to guarantee continuity, or am I just worrying about nothing?
