  • Using ModalAlert from cookbook - app does not load

    - by user127091
    I'm using iphone cookbook code to prompt a user for text in a UIAlertView. The cookbook code is available at http://github.com/erica/iphone-3.0-cookbook-/tree/master/C10-Alerts/03-Soliciting%20Text/ In my AppDelegate, applicationDidFinishLaunching(), I invoke as below NSString *str = [ModalAlert ask:@"what is your name?" withTextPrompt:@"ATTUID"]; But my app does not finish loading at all. I get a black screen indefinitely. There are no messages in the console. I tried creating just a UIAlertView with UITextField in the above function and it displays properly. (commenting out her code) Commenting out "CFRunLoopRun()" also loads the app. I'm probably doing something stupid but can't seem to figure it out.

  • Parallel port no longer accessible even though no changes to system.

    - by marcusw
    I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

  • How to detect exception when executing Javascript in NPAPI plugin?

    - by Jordfräs
    In a plug-in I am using NPN_Evaluate() to execute some Javascript. How can I detect wether the Javascript raises an exception? Basically I want to execute any piece of Javascript and get the result from it or detect if it raised an exception. I tried wrapping my Javascript code like this: try { // Injected Javascript code here } catch (exc) { exc; } That way the result from NPN_Evaluate() will be an NPObject* containing a property "message" with the exception message if something goes wrong. But how can I know that it is an exception? It might as well be a result from the injected Javascript code. Am I approaching this the wrong way? Can I detect an exception without catching it in Javascript and returning the exception as the result?

  • How do I call functions of an object inside the same object?

    - by Roly
    I have the following Javascript code add_num = { f: function(html, num) { alert(this.page); }, page : function() { return parseInt(this.gup('page')); }, gup : function(name) { name = name.replace(/[\[]/,'\\\[').replace(/[\]]/,'\\\]'); var regex = new RegExp('[\\?&]'+name+'=([^&#]*)'); var results = regex.exec(window.location.href); if(results == null) return ''; else return results[1]; } } But when I call add_num.f() what I get from alert() is the actual code of page. That is, it returns function() { return parseInt(this.gup('page')); } I was expecting a numeric value and not any code at all.

  • when is java faster than c++ (or when is JIT faster then precompiled)?

    - by kostja
    I have heard that under certain circumstances, Java programs or rather parts of java programs are able to be executed faster than the "same" code in C++ (or other precompiled code) due to JIT optimizations. This is due to the compiler being able to determine the scope of some variables, avoid some conditionals and pull similar tricks at runtime. Could you give an (or better - some) example, where this applies? And maybe outline the exact conditions under which the compiler is able to optimize the bytecode beyond what is possible with precompiled code? NOTE : This question is not about comparing Java to C++. Its about the possibilities of JIT compiling. Please no flaming. I am also not aware of any duplicates. Please point them out if you are.

  • visual studio 2002: c# threading question

    - by dotnet-practitioner
    Hi, I have a piece of code where I send a file content over tcp/ip channel. There are times when this connection hangs causing entire application to freeze. Is there a way for my main thread to spawn a worker thread and monitor that worker thread. If worker thread succeeds, well and good. If it hangs , the main thread could log error message and continue. How can I simulate in my test code that a worker thread is hanging. please let me know what could the code look like. I am using C# Visual studio 2002.

  • How to add a php page to Wordpress

    - by rutherford
    I want to create a custom page for my Wordpress blog that will execute my php code in it, whilst remaining a part of the overall site css/theme/design. The php code will make use of 3rd party APIs (so I need to include other php files) How do I accomplish this? N.B. I do not have a specific need to interact with the Wordpress API - apart from including certain other php libs I need I have no other dependencies in the PHP code I want to include in a WP page. So obviously any solution that didn't require learning the WP api would be the best one.

  • ASP.NET Build Images Links Dynamically

    - by coson
    Good Day, I am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code): DynamicString = FunctionThatCreatesDynamicString() ' DynamicString = "http://external_server/path/to/file1.jpg" If ImageExists(DyanmicString) = StatusCode.200 Then ' Embed link in ASP.NET page Else ' Embed not found image in ASP.NET page End If My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML. Any thoughts? TIA, coson

  • Accessing a control in asp.net content page through Javascript

    - by rocksolid
    Hi, I have a form in my content page for which I am doing some client side validations via Javascript. The Javascript behaves as expected if I place the JS code directly in the content page. But if I place the JS code in it's own file and try accessing that from the content/master page (through the script tag's src attribute), I get a run time error when the validation function in JS being called. To be specific, I get the below error. Microsoft JScript runtime error: Objected expected/required at this line - document.getElementById('<%=txtemailId.ClientID %').value txtemailId is in the content page. Javascript code is placed in validation.js and accessed via master page. The reason I guess is that when .net is parsing the files, it is unable to substitute txtemailId.ClientID with the client side value that would be generated later on. So, how should one go about it? Thanks!

  • How has test first development changed the way you write software?

    - by Toran Billups
    I've started to find that I can't write software without writing a test first. I ask this subjective question because I want to hear what others in the community think about the reasons I can't go back to writing production code without a test first. If you can't write a test for something you don't understand it Without a regression test you can't clean the code You are going to test it anyway, spend the time to do it right Evolutionary design is possible without fear You actually write less code yourself Fast feedback cycles save time and money Job security (less bugs makes your boss happy) It actually makes my work more enjoyable

  • PHP - Resize an image and fill gaps of proportions with a color

    - by Kerry
    I am uploading logos to my system, and they need to fix in a 60x60 pixel box. I have all the code to resize it proportionately, and that's not a problem. My 454x292px image becomes 60x38. The thing is, I need the picture to be 60x60, meaning I want to pad the top and bottom with white each (I can fill the rectangle with the color). The theory is I create a white rectangle, 60x60, then I copy the image and resize it to 60x38 and put it in my white rectangle, starting 11px from the top (which adds up to the 22px of total padding that I need. I would post my code but it's decently long, though I can if requested. Does anyone know how to do this or can you point me to code/tutorial that does this?

  • SFML 2.0 crashes anytime a method is called

    - by Ken
    This code generates an exception: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; clock.getElapsedTime(); return 0; } However, this doesn't crash: #include <SFML/Graphics.hpp> #include <SFML/Window.hpp> #include <SFML/System.hpp> int main() { sf::Clock clock; return 0; } I'm using SFML 2.0, Windows 7, MinGW 4.70 (Code::Blocks). I don't know why, I followed all instructions to link the libraries and nothing seems to be working. I might be missing something simple through my anger (I've been trying to run sample code for a week, nothing has been working), so can anybody throw me a bone?

  • JQuery Validate Dynamic Table

    - by Richard
    I'm using the JQuery validation plug to validate my entire form. I also have a dynamic table on my registration page where the user can register more people. I can validate the rest of the form fine but my goal is to validate the table inputs just the same. Here is my jfiddle code: tables I don't know why the add line won't work there but it definitely works on my page. Anyway, that code ends up validate ONLY the first row of my table, but I want it to validate every single row. Can anyone see any problems with the code?

  • java.awt.HeadlessException thrown from HeadlessGraphicsEnvironment.getDefaultScreenDevice

    - by Omry
    I need to do some image processing on a java server (Debian with java version "1.6.0_12"), and I am receiving java.awt.HeadlessException from my code: java.awt.HeadlessException at sun.java2d.HeadlessGraphicsEnvironment.getDefaultScreenDevice(HeadlessGraphicsEnvironment.java:64) at WaxOn.getDefaultConfiguration(WaxOn.java:341) Even when java.awt.headless is set to true (as evident by this code printing so): if (!java.awt.GraphicsEnvironment.isHeadless()) { logger.warn("Headless mode is not enabled"); } else { logger.info("Headless mode"); } This is the code that throws the exception: public static GraphicsConfiguration getDefaultConfiguration() { GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gd = ge.getDefaultScreenDevice(); return gd.getDefaultConfiguration(); } Any idea how to solve this?

  • converting a treebank of vertical trees to s-expressions

    - by Andreas
    I need to preprocess a treebank corpus of sentences with parse trees. The input format is a vertical representation of trees, like so: S =NP ==(DT +def) the == (N +ani) man =VP ==V walks ...and I need it like: (S (NP (DT the) (N man)) (VP (V walks))) I have code that almost does it, but not quite. There's always a missing paren somewhere. Should I use a proper parser, maybe a CFG? The current code is at http://github.com/andreasvc/eodop/blob/master/arbobanko.py The code also contains real examples from the treebank.

  • About the fix for the interference between Company mode and Yasnippet

    - by janoChen
    Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) I placed that code in my .emacs and the following message appeared: Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?

  • how to deal with a static analyzer output

    - by Jim
    We have started using a static analyzer (Coverity) on our code base. We were promptly stupefied by the sheer amount of warnings we received (its in the hundreds of thousands) , it will take the entire team a few mounts to clear them all (obliviously impossible). the options we discussed so far are 1) hire a contractor to sort out the warning and fix them - he drawback: we will probably need very experiences people to do all these modifications, and no contractor will have required understanding of the code. 2) filter out the warning and deal only with the dangerous ones - the problem here is that our static analysis output will always be cluttered by warning making it difficult for us to isolate problems. also the filtering of the warning is also a major effort. either way, bringing our code to a state when the static analyzer can be a useful tool for us seems a monumental task. so how is it possible to work with the static analyzer without braining current development efforts into a complete stand still?

  • Visual Studio add-in for performance benchmarking

    - by chiccodoro
    I'd like to measure the performance of some code blocks in my c# winforms application. In particular I want to measure performance regression/improvement after some restructuring of the code. So long I've seen the System.Diagnostics.Stopwatch. However, I want to avoid writing measuring code into my classes, I would rather prefer to separate measuring from actual code. As for debugging, you can set breakpoints on several code lines and "jump" from one to the next by "Continue Execution", I imagine something similar for measuring: Mark to lines of code and make Visual Studio display the time elapsing from one to the next. Is there any feature/add-in in that direction?

  • How can I create a qr// in Perl 5.12 from C?

    - by kristina
    This has been working for me in 5.8 and 5.10, but in 5.12 my code creates this weird non-qr object: # running "print Dumper($regex)" $VAR1 = bless( do{\(my $o = '')}, 'Regexp' ); Whereas printing a qr// not created by my code looks like this: # running "print Dumper(qr/foo/i)" $VAR1 = qr/(?i-xsm:foo)/; My code is basically: REGEXP *rx = re_compile(pattern, flags); SV *regex = sv_2mortal(newSVpv("",0)); sv_magic(regex, (SV*)rx, PERL_MAGIC_qr, 0, 0); stash = gv_stashpv("Regexp", 0); sv_bless(newRV((SV*)regex), stash); Anyone know how to correctly create a regex from a string in 5.12?
