  • set file's icon in a command line utility not working

    - by Ief2
    I just began to work with Objective-C and I'm managing pretty well. My last challenge was to make a command line utility, which I could than use in AppleScript. But my code does not work, not in the terminal, not in the AppleScript. So I'm asking you, what's the error in this peace of code, that should be very plain and easy? int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // -imagePath // -filePath NSUserDefaults *args = [NSUserDefaults standardUserDefaults]; NSString *soundPath = [args stringForKey:@"imagePath"]; NSString *filePath = [args stringForKey:@"filePath"]; BOOL worked = [[NSWorkspace sharedWorkspace] setIcon:[[NSImage alloc] initWithContentsOfFile:soundPath] forFile:filePath options:0]; NSLog(@"Worked: %i",worked); [pool release]; return 0; }

  • Unstyled web page in IE6. Not FOUC

    - by Illes Peter
    I have a very interesting issue with one of the websites I created. It renders fine in Safari, Chrome, Opera, FF, IE7&8 but IE6 does not seem to recognize my stylesheet. I'm not using @import for loading, so it's not a case a FOUC. The website is using Wordpress but never had an issue like this before with WP. I might be missing out on something stupid here, can find the problem though. Any help, suggestion would be very much appreciated. The website is: http://www.magashegyiturak.ro

    - by Jam
    I have a thread pool that loops over a bunch of pages and checks to see if some string is there or not. If String is found, or not found response is near instant, however if server is offline or application is not running getting a rejection seems to take seconds How can I change my code to fail faster? for (Thread thread : pool) { thread.start(); } for (Thread thread : pool) { try { thread.join(); } catch (InterruptedException e) { e.printStackTrace(); } } Here is my run method @Override public void run() { for (Box b : boxes) { try { connection = new URL(b.getUrl()).openConnection(); scanner = new Scanner(connection.getInputStream()); scanner.useDelimiter("\\Z"); content = scanner.next(); if (content.equals("YES")) { } else { System.out.println("\tFAILED ON " + b.getName() + " BAD APPLICATION STATE"); } } catch (Exception ex) { System.out.println("\tFAILED ON " + b.getName() + " BAD APPLICATION STATE"); } } }

    - by Allan
    I do not understand why this code is not valid: #include <vector> template <typename T> class A{ public: A() { v.clear(); } std::vector<A<T> *>::const_iterator begin(){ return v.begin(); } private: std::vector<A<T> *> v; }; When compiling it with gcc, it get the following error: test.cpp:8: error: type 'std::vector<A<T>*, std::allocator<A<T>*> >' is not derived from type 'A<T>' test.cpp:8: error: expected ';' before 'begin' test.cpp:12: error: expected `;' before 'private' What is wrong, and how to fix it??

  • Update database in asp.net not working

    - by Badescu Alexandru
    Hello ! i have in asp.net a few textboxes and i wish to update my database with the values that they encapsulate .

  • Images appear in simulator but not when uploading to ipod touch (3.0)

    - by user139190
    I created a simple test app with an image (as well as a button with an image) and it runs fine in the simulator. But when uploading to the iPod, none of the images appear. The button appears but with no image. A few things worth mentioning: - Today's massive achievement was making it beyond the code signing errors and so I have not had any applications uploaded to the device until now. IOW, it's not a sudden change. - The png image is about 100 x 200. - I also set an icon image (png 24 x 24) that does not appear either. Thanks in advance for any advice.

  • Drupal does not recognize my website has been installed

    - by Marcos Buarque
    After a successful Drupal install, I was trying to follow the security recommendations and reverted the settings.php file to 444 permissions (read, read, read). Then, all of a sudden, right after doing that, Drupal does not recognize the installation process was completed. It went back to the install screen. Worst of all. I did chmod back to 666 (write, write, write) but it does not work any more. When I move forward as if I was going to install Drupal again, he tells me he does not have permissions to create the files folder under sites/default... But since the installation has already been completed... the files folder is already there... I am puzzled... Could it be some sort of server caching? Since this is one of my first adventures with a Linux server, I am a bit confused. Any help appreciated... Thanks.

  • APC not recommended for production?

    - by solomongaby
    I have started having problems with my VPS in the way that it would faill to serve the pages on all the websites. It just showed a blank page, or offered to download the php file ( luckily the code was not in the download file :) ). The server was still running, but this seemed to be a problem with PHP, since i could login into WHM. If i did a apache restart, the sites would work again. After some talks with the server support they told me this is a problem with the APC extension witch they considered to be old and not recommended for production servers. So they removed it for now, to see if the same kind of fails would continue to appear. I haven't read anywhere that APC could have some problems or that its not always recommended to use, quite the contrary ... everywhere people are saying to always use it. The APC extension was installed ssh and is the latest version. Edit: They also dont recomend MemCache and say that a more reliable extension would be eAccelerator

  • Create a javascript chome extention that does not execute in 6 months

    - by user1907657
    I have just started learning programming and I would like to make a script into a chrome extension. Its a basic script and I hope to practice more and more and develop bigger projects and set myself bigger tasks This script has to do the following : reload a page every 20 seconds (say google.com) after 6 months the script must not run (maybe prompt a window saying "its over 6 months") The code should be able to go into a small chrome extension and also the 6 month time period should be absolute not relative to the time the script was started; for example should the browser crash and i have to turn on the extension again it should not restart the 6 month counter. Also if anyone could recommend any good sources for JavaScript to learn (preferably books; nothingIi read online ever seems to stick)

  • Why are Asynchronous processes not called Synchronous?

    - by Balk
    So I'm a little confused by this terminology. Everyone refers to "Asynchronous" computing as running different processes on seperate threads, which gives the illusion that these processes are running at the same time. This is not the definition of the word asynchronous. a·syn·chro·nous –adjective 1. not occurring at the same time. 2. (of a computer or other electrical machine) having each operation started only after the preceding operation is completed. What am I not understanding here?

  • performing auditing in java with sql server DB - before and/or after do not get audited

    - by Domingos
    When auditing, sometimes the before value does not get audited, other times the after value does not get audited, other times both values do not get audited at all. After researching, I found out that only values from a specific codes table get audited. the code was: compareCodesTableInteger(audit, int, int, objectBefore, objectAfter, stringDescription, stringCodesTable); I then changed it to: compareCodesTableInteger(audit, int, int, objectBefore, objectAfter, stringDescription, booleanCheck ? stringCodesTableIfTrue : stringCodesTableIfFalse); Description: if objectBefore AND objectAfter are both from stringCodesTableIfTrue OR from stringCodesTableIfFalse, auditing takes place as expected. The problem is: most of the times, objectBefore is from stringCodesTableIfTrue, and objectAfter is from stringCodesTableIfFalse, or vice-versa. In this scenario auditing fails. How do I go around this? Please assist

  • (NOT) NULL for NVARCHAR columns

    - by Anders Abel
    Allowing NULL values on a column is normally done to allow the absense of a value to be represented. When using NVARCHAR there is aldready a possibility to have an empty string, without setting the column to NULL. In most cases I cannot see a semantical difference between an NVARCHAR with an empty string and a NULL value for such a column. Setting the column as NOT NULL saves me from having to deal with the possibility of NULL values in the code and it feels better to not have to different representations of "no value" (NULL or an empty string). Will I run into any other problems by setting my NVARCHAR columns to NOT NULL. Performance? Storage size? Anything I've overlooked on the usage of the values in the client code?

  • Debug.Assert seems not to work in Mono

    - by Jan-Willem
    Consider the following C# program: using System; using System.Diagnostics; namespace Test { class MainClass { public static void Main (string[] args) { Debug.Assert(false); Debug.Fail("fail!"); Console.WriteLine ("Hello World!"); } } } When compiling this using: dmcs -debug -d:DEBUG Main.cs and then running it with: mono --debug Main.exe the assertion and fail seem to be ignored. The output is just: Hello World! I checked other related questions on StackOverflow, but I could not find a solution. In particular the solution give in Mono - Debug.Assert does not work does not work. (UPDATE: the update solution does work, see below comments.) I use Mono 2.1.5-1 on Ubuntu 11.10.

  • Why is the 'this' keyword not a reference type in C++ [closed]

    - by Dave Tapley
    Possible Duplicates: Why ‘this’ is a pointer and not a reference? SAFE Pointer to a pointer (well reference to a reference) in C# The this keyword in C++ gets a pointer to the object I currently am. My question is why is the type of this a pointer type and not a reference type. Are there any conditions under which the this keyword would be NULL? My immediate thought would be in a static function, but Visual C++ at least is smart enough to spot this and report static member functions do not have 'this' pointers. Is this in the standard?

  • JQuery Validation Plugin not working when used on page that includes another page via AJAX

    - by droidy
    We have a long page that contains a bunch of different form elements. One part of the form is called remotely via AJAX and is populated in an empty div. This is the part which JQuery Validation plugin is not working correctly on. We have class="required" on the elements on this page, but they do not show up as required. I'm guessing it's because the Validation plugin is looking for class="required" on our main page, and since the content from the AJAX page is put into the empty div behind the scenes, it's not detected the required fields. Any help is greatly appreciated.

  • Django template context not working with imported class

    - by Andy Hume
    I'm using Django's templating on appengine, and am having a problem whereby a class I'm importing from another package is not correctly being made available to the template context. Broadly speaking, this is the code. The prop1 is not available in the template in the first example below, but is in the second. MyClass is identical in both cases. This does not work: from module import MyClass context = MyClass() self.response.out.write(template.render(path, context)) This does: class MyClass(object): def __init__(self): self.prop1 = "prop1" context = MyClass() self.response.out.write(template.render(path, context)) If I log the context in the above code I get: <module.MyClass object at 0x107b1e450> when it's imported, and: <__main__.MyClass object at 0x103759390> when it's defined in the same file. Any clues as to what might cause this kind of behaviour?

  • Custom Extension not showing up wthin experimental instance

    - by user1333524
    I have a VSIX extension that I created which shows up in Visual Studio 2010 and works as designed. However I am attempting to build some Visual Studio automation which relies on this Extension and although its present in the project where I am building my automation package, when I run the package project, the visual studio experimental solution loads no problem, however when I look within the Extension Manager I do not see my registered Extension (even though it shows up within my Visual Studio project where I am building my extension. The extension is a custom shell for LightSwitch which may be a clue as to why it is not showing within my experimental instance of Visual Studio, not sure as I see other extensions I built and registered for LightSwitch showing up. Of course my issue is that when I attempt to load a solution that has a dependency on my LightSwitch extension, which otherwise loads fine outside of the Experimental Instance, fails due to the fact it can't locate my custom extension when I try to load the solution within my experimental solution.

  • What is the reason not to use select * ?

    - by Chris Lively
    I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?

  • File.Exists() returns false, but not in debug

    - by Tor Haugen
    I'm being completely confused here folks, My code throws an exception because File.Exists() returns false public override sealed TCargo ReadFile(string fileName) { if (!File.Exists(fileName)) { throw new ArgumentException("Provided file name does not exist", "fileName"); } Visual studio breaks at the throw statement, and I immediately check the value of File.Exists(fileName) in the immediate window. It returns true. When I drag the breakpoint back up to the if statement and execute it again, it throws again. fileName is an absolute path to a file. I'm not creating the file, nor writing to it (it's there all along). If I paste the path into the open dialog in Notepad, it reads the file without problems. The code is executing in a background worker. It's the only complicating factor I can think of. I am positive the file has not been opened already, either in the worker thread or elsewhere. What's going on here?

  • Displaying objects based on if a user is logged in or not

    - by MaxMackie
    I'm learning about PHP sessions for user authentication on my website. I know how to restrict the viewing of a complete page using sessions (simply check if the 'uid' session variable is set and if it is, show content, if not redirect to an error). However I'm trying to figure out the best way to selectively show and hide different objects (div, text, images) based on if a user is logged in or not. Is it as simple as checking for the 'uid' session variable and displaying based on if it set or not? Is there a more efficient way of doing this id there are a lot of conditional elements on a page?

  • Selecting elements that do not contain a certain ID using ExtJS

    - by pmdarrow
    I'm trying to select all the <input> elements of a form except ones with IDs containing the words foo or bar. How can I do this using ExtJS 2.3.0? I've tried the following: Ext.query("select,input:not([id*=foo][id*=bar])", "SomeForm");` ... but it doesn't work. Excluding IDs with foo in them seems to work fine: Ext.query("select,input:not([id*=foo])", "SomeForm")` I'm just not sure how to add a second ID substring. Any Ideas?

  • IE - hidden radio button not checked when the corresponding label is clicked

    - by ScottE
    I just noticed a strange behaviour in IE7. I have radio buttons with associated labels as follows: <input type="radio" name="filter" id="filter_1" value="Activities" checked="checked" /> <label for="filter_1">Activities</label> <input type="radio" name="filter" id="filter_2" value="Services" /> <label for="filter_2">Services</label> The radio button is hidden via css with display:none or visibility: hidden (don't ask) The problem is - when I click the label in IE7 (haven't looked at other IE versions yet) the associated radio button is not actually checked. I confirmed this with jquery - the label click event is fired, but the radio button click event is not. A form post also confirms that the checked radio button does not change. This works correctly in firefox, and also works correctly if I remove the CSS that hides the radio buttons. Is this an IE bug or am I missing something?

  • Windows Mobile 6.5 flick (scrolling with inertia) not working

    - by GRR
    After upgrading to windows mobile 6.5, my ListView control does not work properly with custom items (rows with alternate colors) and the new gesture mechanism... On a mobile device, if the user initiates a flick or pan, after scrolling the first few items, the last items are not shown on the screen, but will show up if the user explicitly taps on them -- so basically the last screen is just white. The WM_DRAWITEM message is sent to all children though, but they just don't show up on the screen. Scrolling with a bar works fine. Any ideas? I have seen some reports of similar behavior from other users, but not sure if this is a bug in the listview control itself or if there is something else that needs to/can be implemented to support flick and pan actions. The application code currently doesn't handle WM_GESTURE messages, so the flick action is done with Microsoft's own code to support legacy applications. Thanks!

  • javan-whenever not writing crontab with Capistrano deploy

    - by Gordon Isnor
    I’ve been trying to get whenever running on an ec2 instance that was created with ec2 on rails. When I deploy with Capistrano it indicates that the crontab was written, but when I log into the server and run crontab -l it does not seem to have been changed. If I go into the release folder and manually run whenever --write-crontab then run crontab -l - it gets updated properly. Any ideas what could be causing this? Capistrano is not indicating any errors so not sure how to debug, have tried a billion permutations and combinations and nothing changes.
