  • How to resolve parse error in Splint

    - by Thi
    Splint is not continuing it's checking after finding parse errors. I've tried with +trytorecover option also but no change. Please let me know on how to use +trytorecover to make Splint attempt to continue after a parse error. Here is what I'm receiving, 161: splint +trytorecover spy.c Splint 3.1.1 --- 19 Jul 2006 spy.c:41:12: Parse Error: Non-function declaration: byte_4 : int. Attempting to continue. spy.c:41:12: Cannot recover from parse error. *** Cannot continue.

  • Rails: getting logic to run at end of request, regardless of filter chain aborts?

    - by JSW
    Is there a reliable mechanism discussed in rails documentation for calling a function at the end of the request, regardless of filter chain aborts? It's not after filters, because after filters don't get called if any prior filter redirected or rendered. For context, I'm trying to put some structured profiling/reporting information into the app log at the end of every request. This information is collected throughought the request lifetime via instance variables wrapped in custom controller accessors, and dumped at the end in a JSON blob for use by a post-processing script. My end goal is to generate reports about my application's logical query distribution (things that depend on controller logic, not just request URIs and parameters), performance profile (time spent in specific DB queries or blocked on webservices), failure rates (including invalid incoming requests that get rejected by before_filter validation rules), and a slew of other things that cannot really be parsed from the basic information in the application and apache logs. At a higher level, is there a different "rails way" that solves my app profiling goal?

  • creating ports and initiating communication between client and server

    - by dave
    what i need is a server that listens to 5060 port , when the client sends data to that port the server should open up another port ( any port after 1250 i believe ) and forward the clients data to that port keeping 5060 idle so it can perform the same function for the next client so basically i need the server to a) open up multiple ports one for each client b) get the voice data from the client and be able to send voice data to that client i m looking into the hardware specs and other such details of the scenario so i dont have time to make such a program myself if theres a code that i can run directly ( both server and client side ) on visual studio .net 2010 that will perform these tasks then that would be extremely helpful thanks alot in advance

  • How to leave out some statements while executing java code?

    - by iamrohitbanga
    In C++ if we do not want some statements to compile into code that ships like assert function calls, we control their compilation through #ifndef preprocessor directives. How do we do this in Java? I have some System.out.println() statements for debugging which I would like to remove for the final code. one way is to make them execute conditionally under the affect of a boolean variable. Is there a better way of doing this? As I have a java swing application I can turn off the System.out.println statements without affecting the output. What is the method of doing this?

  • Codeigniter Template library, add_js() method

    - by Karl
    using This Template Library when i try and use the add_js() function it errors out. I add the regions $_scripts to the template header file but when i load the page it says undefined variable _scripts. any thoughts? changed <?= $_scripts ?> to <?= (isset($_scripts)) ? $_scripts : “”; ?> and obviously i lose the error but the js file still isnt loading. I did an echo at each step though the add_js() method and the output is correct. I also did an output of $this-js and they both had the corret output. So it gets through the get_js method fine and sets the class variable fine but i dont get anything added to the actual page.

  • Install device driver silently on Windows XP

    - by mt_serg
    Is there a way to programmatically install device driver silently without cat file and without connecting the device on Windows Xp? I'm using DriverPackageInstall function from Windows Driver Kit. And I can install driver only if device is attached. In other case I get an error: ERROR_NO_SUCH_DEVINST. But that method works fine with Windows Vista. Another problem is warning dialog that asks user to continue or stop installation because cat file is missing . It shows on both OSes. Any ideas?

  • breaking out from socket select

    - by kamziro
    I have a loop which basically calls this every few seconds (after the timeout): while(true){ if(finished) return; switch(select(FD_SETSIZE, &readfds, 0, 0, &tv)){ case SOCKET_ERROR : report bad stuff etc; return; default : break; } // do stuff with the incoming connection } So basically for every few seconds (which is specified by tv), it reactivates the listening. This is run on thread B (not a main thread). There are times when I want to end this acceptor loop immediately from thread A (main thread), but seems like I have to wait until the time interval finishes.. Is there a way to disrupt the select function from another thread so thread B can quit instantly?

  • Php code not executing - dies out when trying to refer to member of static class - no error displaye

    - by Ali
    I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :( =============EDIT SOrry I checked again the error is prior to teh object creation thing - it dies out when it tries to refer to a constant in a static class like so: $v = Zend_Oauth::REQUEST_SCHEME_HEADER; THis is the class or part of it - it has largely static functions its the Zend Oauth class: class Zend_Oauth { const REQUEST_SCHEME_HEADER = 'header'; const REQUEST_SCHEME_POSTBODY = 'postbody'; const REQUEST_SCHEME_QUERYSTRING = 'querystring'; // continued LIke I said no error is being reported at all :(

Here are the steps we are following : Creating object for database utils inteface Calling the connect() function, to get connected to the database whose extension is .mdb file Above flow is working correct on all windows platform but not on windows server 2008 CORE 32-bit.

  • How do I add a Marker to a jQuery UI Slider?

    - by Bijan
    I have a simple jQuery UI slider that has a numerical range from 25 to 35. It works fine and the default value is 28. I'm hoping to add a simple tick mark to the slider to indicate that 28 is where the default is. Is there a simple way to add an indicator? $('#cycle_length').slider({ range: "min", value: 28, min: 25, max: 35, step: 1, slide: function( event, ui ) { $( "#amount" ).val( ui.value ); } }); $( "#amount" ).val( $( "#cycle_length" ).slider( "value" ) );

  • Python library to detect if a file has changed between different runs?

    - by Stefano Borini
    Suppose I have a program A. I run it, and performs some operation starting from a file foo.txt. Now A terminates. New run of A. It checks if the file foo.txt has changed. If the file has changed, A runs its operation again, otherwise, it quits. Does a library function/external library for this exists ? Of course it can be implemented with an md5 + a file/db containing the md5. I want to prevent reinventing the wheel.

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • Is there a way to convert code to a string and vice versa in Python?

    - by Dragos Toader
    The original question was: Is there a way to declare macros in Python as they are declared in C: #define OBJWITHSIZE(_x) (sizeof _x)/(sizeof _x[0]) Here's what I'm trying to find out: Is there a way to avoid code duplication in Python? In one part of a program I'm writing, I have a function: def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) In another part, I've got this code embedded in a string that will later be output to a python file that will itself be run: """ def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) """ How can I build a "macro" that will avoid this duplication?

  • Design pattern: polymorphisim for list of objects

    - by ziang
    Suppose I have a class A, and A1, A2 inherits from A. There are 2 functions: List<A1> getListA1(){...} List<A2> getListA2(){...} Now I want to do something similar to both A1 and A2 in another function public void process(List<A>){...} If I want to pass the instance of either ListA1 or ListA2, of course the types doesn't match because the compiler doesn't allow the coercion from List< A1 to List< A. I can't do something like this: List<A1> listA1 = getListA1(); List<A> newList = (List<A>)listA1; //this is not allowed. So what is the best approach to the process()? Is there any way to do it in a universal way rather than write the similar code to both List and List?

  • Getting specific values with regex

    - by David
    I need to knowingly isolate each row of the vCard and get its value. For instance, I want to get "5555" from X-CUSTOMFIELD. So far, my thoughts are: "X-CUSTOMFIELD;\d+" I have been looking at some tutorials and I am a little confused with what function to use? What would my regex above return? Would it give me the whole line or just the numerical part (5555)? I was thinking I i get the whole row, I can use substring to get the digits? BEGIN:VCARD VERSION:2.1 N:Last;First; FN:First Last TEL;HOME;VOICE:111111 TEL;MOBILE;VOICE:222222 X-CUSTOMFIELD;5555 END:VCARD

  • How can I program ksh93 to use bash autocompletion?

    - by Norman Ramsey
    In a comment in response to a shell question, user tinkertim said that it was easy to hack ksh to use the bash autocompletion library. I would like nothing better than to use bash autocompletion with AT&T ksh93. How can this be done? ksh93 has a new release several times a year, so I am looking for a solution that does not involve modifying the source code. ksh93 can link new C modules dynamically and also is highly programmable (I run a ksh function at every keystroke), so modifying the source should not really be necessary. Note: I am not talking about filename autocompletion, which is easy to do in ksh. I'm talking about all the other yummy autocompletion stuff that bash does, like autocompletion options for nmh commands or autocompleting Mercurial commmands. Stuff like that.

  • gVim and multiple programming languages

    My day job involves coding with Perl. At home I play around with Python and Erlang. For Perl I want to indent my code with two spaces. Whereas for Python the standard is 4. Also I have some key bindings to open function declarations which I would like to use with all programming languages. How can this be achieved in gVim? As in, is there a way to maintain a configuration file for each programming language or something of that sort?

  • [Android] GPS can't run inside TimerTask

    - by user568553
    Hi, I am trying to write an android app that acquires a GPS signal at a fix time interval, for example every 1 minute. Since the requestLocationUpdate function does not exactly implement that, I tried to use task to accomplished it. public class getGPS extends TimerTask{ public void run(){ System.out.println("Running a GPS task"); locHandler = new locationUpdateHandler(); myManager.requestLocationUpdates(provider, 60000, 0, locHandler); } } public void LoadCoords(){ Timer timer = new Timer(); timer.scheduleAtFixedRate(new getGPS(), 0, 60000); } However, from what I've seen, requestLocationUpdates would run fine if I put it inside LoadCoords(), but would not run if I put it inside the TimerTask (ie no green icon on the task bar to show that GPS is looking for a fix). Can anyone please suggest an alternative approach or pseudo-code, or correct my mistake if there is one ? Thank you in advance.

  • What's the best way to call jQuery scripts, in HTML/PHP template, or seperate js file?

    - by j-man86
    StackOverflow is telling me this is a subjective question, but I think it's a matter of fact! I have a number of scripts that I'm using on different parts of my site. In terms of making fewer http requests, I know it's better to combine all of these scripts into one .js file. However, isn't a waste of time for a page to call a .js full of 10 or 15 different functions when it's only using one? The other method I am using is to use PHP conditional statements... <?php if( is_page() ) { > $(document).ready(function(){ ... }); <?php } ?> What's the best method or comination of these methods?

  • jquery select problem

    - by codedude
    Say I have an unordered list like so: <ul> <li>Some Text</li> <li>Some Text</li> <li>Some Text</li> <li>Some Text</li> </ul> I want to use jquery so that when I click a "li", the background changes to blue. So I do this: $('li').click(function() { $(this).addClass('active'); }); And the "active" class has as background of blue. However, I can't figure out how to make it so that when I click another "li", the other "li" that has a background of blue stops having a background of blue. I guess what I'm trying to say is how to make only one "li" have a background of blue at a time--using jquery.

  • Using opencv in Win32 application for image show

But If I want to look at more than one image, then every new image needs its own window to be shown there And what I want is to put every such an output opencv's window inside one big main window.
