  • 'NSInvalidArgumentException' UIButton IBAction Error

    - by Graeme
    Hi, I have a button in a view which refuses to work. I've got in working in a blank, default view application from X-Code, but in none of my applications will it work, instead it gives me the following error. Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController showVicInfo:]: unrecognized selector sent to instance 0x3c084f0' The debugger isn't any help either. I've made sure that I hook up the button to the file's owner (not the other way around) as well. Below is the code for the action. And I know it's not the alert view, because the breakpoint doesn't even reach there. about.h @interface about : UIViewController { } -(IBAction)showInfo:(id)sender; about.m -(IBAction)showVicInfo:(id)sender { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"You require an internet connection via WiFi or cellular network for iFirelert to work." delegate:self cancelButtonTitle:@"OK, thanks" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

  • Configure JBOss cache to run on JBoss server 4.2.3.GA

    - by Spiderman
    Our commercial application used to run on different application server and letely we started adjust it to run on JBoss server. The problem is that that application runs JBoss cache and as part of the integration with this framework, the web-inf\lib contains the follwing jars: jboss-aop.jar, jbosscache-core.jar, jboss-common.jar, jboss-common-core.jar, jboss-j2ee.jar, jboss-jmx.jar, jboss-logging-spi.jar This causes a problem to use JNDI through the application because the jboss-common-core.jar contain naming package that cause JBoss JNDI to work incorrect. So I need to find a way to organise my jars that on one hand jboss cache will keep working and on the other hand not to interfere to the work of JNDI Perhaps it include moving the some or all those jars from the web-inf\lib to the /server/default/lib Looking for someone who is familiar in this subject (continue of this thread: http://stackoverflow.com/questions/2847375/problem-configure-jboss-to-work-with-jndi3 )

  • Dynamically enable or disable RequiredFieldValidator based on value of DropDownList

    - by Jeremy
    I have an ASP.NET form with three text inputs, one each for "Work Phone", "Home Phone" and "Cell Phone". Each of these text inputs has a RequiredFieldValidator associated with it. I also have a DropDownList where the user can select the preferred phone type. I want to only require the field that is selected in the DropDownList. For example, if the user selects "Work Phone" from the DropDownList, I want to disable the RequiredFieldValidator for "Home Phone" and "Cell Phone", thereby only making the "Work Phone" field required. I have a method that enables and disables these validators based on the value of the DropDownList, but I cannot figure out when to call it. I want this method to run before the validation takes place on the page. How would I do that?

  • Prawn PDF with Rails mailer?

    - by Danny McClelland
    Hi Everyone, I have successfully created an email that sends on creation of a Kase, but now I need to attach a PDF that is created on the fly by Prawn and Prawno. Basically when you visit a kase such as application.com/kase/1 you just append the URL with .pdf i.e. application.com/kase/1. I spent ages getting the PDF to work and look how I wanted, but I can't figure out how to add the PDF to an auto sending email - mainly because I cannot work out how to give it a link as it's auto generated. Has anyone ever managed to get this to work? Thanks, Danny

  • IE8 AJAX GET setRequestHeaders not working unless params provided in URL

    - by bobthabuilda
    I'm trying to create an AJAX request in IE8. var xhr = new ActiveXObject( 'Msxml2.XMLHTTP' ); xhr.open( 'GET', '/ajax/' ); // Required header for Django to detect AJAX request xhr.setRequestHeader( 'X-Requested-With', 'XMLHttpRequest' ); xhr.onreadystatechange = function() { if ( this.readyState == 4 ) console.log(this.responseText); } xhr.send( null ); This works perfectly fine in Firefox, Chrome, Safari. In IE8 however, all of my AJAX test requests work EXCEPT for ones where I'm performing GETs without any query string params (such as the one above). POSTs work without question, and GET requests only work whenever I include query strings in the URL, like this: xhr.open( 'GET', '/ajax/?foo=bar' ) I'm also 110% positive that my server code is handling these requests appropriately, so, this stumps me completely. Does anyone have any clue as to what might be causing this?

  • What is CDbl doing?

    - by Dan Tao
    I had until recently been under the impression that the CDbl(x) operation in VB.NET was essentially a cast (i.e., the VB equivalent of (double)x in C#); but a recent discovery has revealed that this is not the case. If I have this string: Dim s As String = "12345.12345-" And I do this: Dim d As Double = CDbl(s) d will be set to the value -12345.12345! Now, don't get me wrong, this is kind of convenient in my particular scenario; but I have to admit I'm confused as to why this works. In particular, I'm confused because: Double.Parse does not work with the above input. Double.TryParse does not work. Convert.ToDouble does not work. How is CDbl so clever?

  • Why can't I input the integers from a file?

    - by Anthony Glyadchenko
    I'm trying to get this C++ code to input a series of numbers from a text file: int x = 0; cin >> x; ifstream iffer; int numbers[12]; iffer.open("input.txt"); for (int i = 0; i < 12; i++){ iffer >> numbers[i]; } This doesn't seem to work on the Mac. Every cell will equal to 0 regardless of the values in the text file. In other words, the ifstream isn't assigning the numbers. How can I make this work? Is it a Mac issue and if so, how can I get it to work? Thanks! Anthony Glyadchenko

  • Which Secure Software Development Practices do you Employ?

    - by Michael Howard-MSFT
    I work on a project known as the Security Development Lifecycle (SDL) project at Microsoft (http://microsoft.com/sdl) - in short it's a set of practices that must be used by product groups before they ship products to help improve security. Over the last couple of years, we have published a great deal of SDL documentation, as customers ask for more information about what we're doing. But what I'd like to know is: 1) What are you doing within your organization to help improve the security of your product? 2) What works? What doesn't work? 3) How did you get management to agree to this work? Thanks.

  • javascript regex: match altered version of first match with only one expression

    - by theseion
    Hi there I'm writing a brush for Alex Gorbatchev's Syntax Highlighter to get highlighting for Smalltalk code. Now, consider the following Smalltalk code: aCollection do: [ :each | each shout ] I want to find the block argument ":each" and then match "each" every time it occurrs afterwards (for simplicity, let's say every occurrence an not just inside the brackets). Note that the argument can have any name, e.g. ":myArg". My attempt to match ":each": \:([\d\w]+) This seems to work. The problem is for me to match the occurrences of "each". I thought something like this could work: \:([\d\w]+)|\1 but the right hand side of the alternation seems to be treated as an independent expression, so backreferencing doesn't work. So my question is: is it even possible to accomplish what I want in a single expression? Or would I have to use the backreference within a second expression (via another function call)? Cheers.

  • SQL Server 2008 Management Studio doesn't recognize new Schema

    - by Lieven Cardoen
    I have created a new Schema in a database called Contexts. Now when I want to write a query, Management Studio doesn't recognize the tables that belong to the new Schema. It says: 'Invalid object name Contexts.ContextLibraries'... Transact-SQL: INSERT INTO [Contexts].[ContextLibraries] (ChannelId, [IsSystem]) VALUES (@ChannelId, 1) When I try the same thing on my local database, it does work... Any ideas? I did try to change the Default schema for the user from dbo to Contexts but this doesn't work. Also checked Contexts in Schemas owned by this user without success. Update: Apparently the sql query does work but the editor gives a fault saying the object is invalid.

  • Running directx samples on a Windows Mobile 6.1 device

    - by Sil
    I tried to run the directx samples from ..\Windows Mobile 6 SDK\Samples\PocketPC\CPP\win32\directx\d3dm\tutorials on a Samsung Omnia and on the emulator and it doesn't work because of a deployment error. I am using Microsoft Visual Studio 2008 and have installed Windows Mobile SDK Standard and Professional refresh. The device is correctly plugged in and set up for active sync (I know this because other samples work, also a creating Win32 smart device and running it works). When I try to run the application it compiles without errors but the message: " There were deployment errors, Continue? Yes/No" appears If I manually copy the application from the debug folder to the device and run it from there, it works. The same deployment error message appears if I try it on an emulator. Other applications are deploying successfully. Is there any way to make the deployment work? Maybe there is an obscure option I need to set...

  • Stubbing ActiveRecord result arrays

    - by Matthias
    Using Ruby 1.8.6, stubbing a finder method to return an Array does not work when the code under test calls the 'count' method on the result: User.any_instance.stubs(:friends).returns([user1, user2]) That's because Array.count has only been added in Ruby 1.8.7. Rails also adds a count method dynamically, I believe through the ActiveRecord::Calculations module. Is there any way to turn this result array into something that behaves exactly as the special Array kind returned by a Rails finder method? When paginating results, it's easy: I can simply call [].paginate. But that doesn't work with normal finder results. I tried [].extend(ActiveRecord::Calculations) but that doesn't work either.

  • Javascript Intellisense not working on Visual Studio 2010 Ultimate (Windows 7 x64)

    - by emzero
    Hi guys, I've just got the new Visual Studio 2010 Ultimate and Javascript Intellisense is not working on .aspx/.ascx files inside blocks. It does work on external .js files. After VS2010 setup, it asked me if I wanted to import the settings from previous VS version (I have VS2008 SP1 installed), I say yes. I've tried resetting the settings like explained here. Didn't work. I've also installed Resharper 5. I thought it might be conflicting, so I tried suspending it like it says here. Didn't work. Anyone experiencing the same issue? I really want javascript/jQuery intellisense =(

  • Why don't these class attributes register?

    - by slypete
    I have a factory method that generates django form classes like so: def get_indicator_form(indicator, patient): class IndicatorForm(forms.Form): #These don't work! indicator_id = forms.IntegerField(initial=indicator.id, widget=forms.HiddenInput()) patient_id = forms.IntegerField(initial=patient.id, widget=forms.HiddenInput()) def __init__(self, *args, **kwargs): forms.Form.__init__(self, *args, **kwargs) self.indicator = indicator self.patient = patient #These do! setattr(IndicatorForm, 'indicator_id', forms.IntegerField(initial=indicator.id, widget=forms.HiddenInput())) setattr(IndicatorForm, 'patient_id', forms.IntegerField(initial=patient.id, widget=forms.HiddenInput())) for field in indicator.indicatorfield_set.all(): setattr(IndicatorForm, field.name, copy(field.get_field_type())) return type('IndicatorForm', (forms.Form,), dict(IndicatorForm.__dict__)) I'm trying to understand why the top form field declarations don't work, but the setattr method below does work. I'm fairly new to python, so I suspect it's some language feature that I'm misunderstanding. Can you help me understand why the field declarations at the top of the class don't add the fields to the class? In a possibly related note, when these classes are instantiated, instance.media returns nothing even though some fields have widgets with associated media. Thanks, Pete

  • Matching n parentheses in perl regex

    - by coding_hero
    Hi, I've got some data that I'm parsing in Perl, and will be adding more and more differently formatted data in the near future. What I would like to do is write an easy-to-use function, that I could pass a string and a regex to, and it would return anything in parentheses. It would work something like this (pseudocode): sub parse { $data = shift; $regex = shift; $data =~ eval ("m/$regex/") foreach $x ($1...$n) { push (@ra, $x); } return \@ra; } Then, I could call it like this: @subs = parse ($data, '^"([0-9]+)",([^:]*):(\W+):([A-Z]{3}[0-9]{5}),ID=([0-9]+)'); As you can see, there's a couple of issues with this code. I don't know if the eval would work, the 'foreach' definitely wouldn't work, and without knowing how many parentheses there are, I don't know how many times to loop. This is too complicated for split, so if there's another function or possibility that I'm overlooking, let me know. Thanks for your help!

  • What is the difference between #ifdef __IPHONE_3.2 and #if __IPHONE_3.2?

    - by Jonathan
    Hi, I have an iphone app that needs to work for 3.1.3 for the iPhone and 3.2 for the iPad. It is an iPhone app that I want to work on the iPad. The main difference is the MPMoviePlayerController which introduces/and deprecates lots of things in 3.2. Since, the iPhone OS only goes up to 3.1.3 and the iPad is on 3.2, I need to seperate my code so it only compiles the required code for the respective OS. I can't use [[UIDevice currentDevice] model] because I end up with deprecated warnings on the 3.1.3 code. Also, UIUserInterfaceIdiomPad is new in 3.2 so it doesn't work well with 3.1.3... So, I decided to use this, which only compiles what is necessary for the particular OS: #if __IPHONE _3_2 //do 3.2 iPad stuff #else //do 3.1.3 iPhone/iPod Touch stuff #endif My question is... What is the difference between these? #ifdef __IPHONE_3_2 and #if __IPHONE_3_2 Thank you

  • Flash "Play" button doesn't play video unless you hit rewind or fast forward

    - by Jack Marchetti
    So I had an IE issue with flash videos continuing to play even when their DIV's display property was set to none ( $('flashdiv').hide(); ) So I was able to solve this problem, by using .detach() and then reinserting the div. This worked great, however the problem now is that the "play" button doesn't work. However, if I hit rewind, or fast forward, it plays, and the play/stop button work fine. The way I'm reinserting the divs is like this: var divid = $('#flashdiv').clone('true'); and then to reinsert: $('#test').html(divid); Any idea why the play button would not work?

  • Adding relative path for an external graphic in a XSL document?

    - by Pran
    Hi, first of, I don't know much about XSL. I am using a app called DITA to generate pdfs. One of the things it requires is an overwrite of an xsl file; to add custom styling. I am trying to add an external graphic using a relative path. It doesn't work, unless I supply the full path. Does not work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="../../images/logo.png"/> </fo:block> Does work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="/absolute/path/to/images/logo.png"/> </fo:block> I looked on the web, it said to use "file:image.png" and other website said to use "url(image.png)", but neither worked. What am I doing wrong?

  • Unit tests only run automatically when active SDK is "simulator"?

    - by Steve Madsen
    I have followed the instructions Apple publishes for unit testing applications on iPhone and things work great when I set the active SDK to "iPhone Simulator". I have it configured to always build and run my tests as part of building the application itself. Apple implies (by omission) that this should work all of the time, but the tests are skipped when I set the active SDK to "iPhone Device". I am also linking with OCMock, and instead of a failing test, this warning is in the build log: ld: warning: in .../build/Debug-iphoneos/OCMock.framework/OCMock, missing required architecture arm in file It's very nice to make the unit test bundle a dependency of the main application, so these tests run at every build, but its utility is greatly diminished if it doesn't work during device builds. Is this a known, but undocumented, limitation?

  • JPEG image with alpha channel on website

    - by mikez302
    I would like to make a JPEG image file with some pixels that are partially transparent or fully transparent, similar to a PNG file with an alpha channel. Is this possible? If so, how would I go about doing this? I would like to use the image on a website. If I try to do this, would it work in any or all of the popular browsers (IE 7+, Firefox, Safari)? Assuming it is possible, will it just work, or are there any tricks or hacks required to make it work?

  • Jetty 6 to Jetty 7 upgrade: what happened to system property "jetty.lib"? (-Djetty.lib=my/lib/dir)

    - by StaxMan
    Looks like Jetty team wanted to do some spring cleaning between versions 6 and 7, and it looks as if one useful system property, "jetty.lib" either does not exist, does not work, or just has changed in an unspecified way so as to make my jetty 6 set up work easily with Jetty 7. I tried searching through Jetty 7 docs, but about the only reference I saw was that "some commonly used properties (such as "jetty.home") still work as they used to". So, what am I missing? I really would want to avoid messing with things within Jetty distribution dirs (otherwise I could -- and maybe I have to? -- just use JETTY_BASE/lib/ext), and that's what "jetty.lib" was useful for.

  • Bibtex with no references title

    - by Bryan Ward
    I am working on writing a scientific poster in LaTeX, and I want to include a few references for my work. Because this is a poster, I have my own customized headers for different sections, and don't want my related works to have a separate title. Essentially I have something like this: \begin{textblock}{5.5}(19.5,11) \CHead{Related Work} %a newcommand header I wrote \bibliographystyle{acm} \bibliography{mybib} \end{textblock} And it comes out with a header called "Related Work" like I want, but it also under that says "References", which I don't want. I found a few websites that said that I could override this with something like \renewcommand\refname{} But all this does is take the word "References" out, but the space allotted for the title is still there. Is there a way to completely eliminate the title and any space it may take up?

  • GWT's JSONParser producing incorrect values for numbers.

    - by WesleyJohnson
    I'm work with GWT and parsing a JSON result from an ASP.NET webservice method that returns a DataTable. I can parse the result into a JSONvalue/JSONObject just fine. The issue I'm having is that one my columns in a DECIMAL(20, 0) and the values that are getting parsed into JSON aren't exact. To demonstrate w/o the need for a WS call, in GWT I threw this together: String jsonString = "{value:4768428229311981600}"; JSONObject jsonObject = JSONParser.parse( jsonString ).isObject(); Window.alert( jsonObject.toString() ); This in turn alerts: {"value":4768428229311982000} I'm under the understanding that GWT's JSONParser is just using eval() to do the parsing, so is this some sort of number/precision issue with JavaScript that I've never been aware of. I'll admit I don't work with numbers that much in JavaScript and I might be able to work around this by changing the .NET WebService to return this column as string, but I'd really rather not do that. Thanks for any help.
