  • Using Jquery $getJSON How do I dynamically create data for the [data] parameter after Url param?

    - by Breadtruck
    I have no problems getting the Json to work and parse the json return. I was just wondering how I could build a dynamic "whatever data is" and stick it into [data] to pass my parameters from there and not manually append them to the url. From jquery website example: $.getJSON("test.js", { name: "John", time: "2pm" }, function(json){ alert("JSON Data: " + json.users[3].name); }); I thought I could build a string ( which doesn't make sense anyway ) and drop it inside the { }, but I obviously don't understand that part. name: isn't a string and you can't put a variable in that part, so how would I dynamically put items into whatever [data] is.

  • Using Session Variables inside an ajax document

    - by Pete Herbert Penito
    Hi, For some reason I've having problems reading this session variable within an ajax document, I've got this inside online.php: ` session_start(); if (isset($_SESSION['username'])) { $username = $_SESSION['username']; } ` For some Reason this is not setting username even when the session var is being used on the host page, i call on the php file every second using this ` $(document).ready(function() { var refreshId = setInterval(function() { $('#timeval').load('online.php'); }, 1000); $("#stop").click(function() { clearInterval(refreshId); }); }); ` Am I doing something wrong, or is this not even possible?? Any advice would really help thanks alot!

  • const read only local copies

    - by robUK
    Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a read-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on read-only local copies, as it confirms to anyone reading my code that it is a read-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

  • "Compiling" content with short tags to var, without eval()

    - by Spot
    To start off, let me clear the air by saying we are aware of the dis/advantages to using short tag syntax in PHP. That is not what this question is about. Is there a way to "include" a file containing short tag code, into a variable, and have PHP actually parse the code? include/require obviously do not provide the data in a workable form, and output buffering does not parse the short tag code because it happens at runtime. Using eval() is simply not an option. Suggestions?

    - by Diego Martinez
    I need apply a variable sequence of templates to an argument. example 1: arg:tpl1():tpl2():...:tplN() Suppose that i have other multi valued argument, and each value is the name for a dynamic template invocation. ¿What is the better form of apply all the templates from the list to my argument? tplNames : {name | <(name)(arg)>} not works, just apply a template ever to the same innitial value of my argument, i need the same result of example 1 but in a dynamic way. Thank you!!

  • php domDocument variables

    - by geoffs3310
    Hi, I have the following code at the moment: $ip = '195.72.186.157'; $xmlDoc = new DOMDocument(); $xmlDoc->loadXML(file_get_contents('http://www.geoffmeierhans.com/services/geo-locator/locate/?ip='.$ip.'&output=xml')); foreach($xmlDoc->getElementsByTagName('city') as $link) { $links = array('text' => $link->nodeValue); } $city = $links['text']; echo $city; Is there a better way to get the city variable? Since there is only one tag called city a loop isn't really needed but I can't get it to work any other way

  • How to debug/reformat C printf calls with lots of arguments in vim?

    - by Costi
    I have a function call in a program that I'm maintaining has 28 arguments for a printf call. It's printing a lot of data in a CSV file. I have problems following finding where what goes and I have some mismatches in the parameters types. I enabled -Wall in gcc and I get warnings like: n.c:495: warning: int format, pointer arg (arg 15) n.c:495: warning: format argument is not a pointer (arg 16) n.c:495: warning: double format, pointer arg (arg 23) The function is like this: fprintf (ConvFilePtr, "\"FORMAT3\"%s%04d%s%04d%s%s%s%d%s%c%s%d%c%s%s%s%s%s%s%s%11.lf%s%11.lf%s%11.lf%s%d\n", some_28_arguments_go_here); I would like to know if there is a vim plugin that highlights the printf format specifier when i go with the cursor over a variable. Other solutions? How to better reformat the code to make it more readable?

  • Get jQuery Error if PHP Breaks

    - by Norbert
    I have a PHP script that breaks if a variable is not populated and it isn't added to the database, but jQuery handles this as a success and I get this error: TypeError: Result of expression 'data' [null] is not an object. Here's the jQuery script: $.ajax({ type: "POST", url: "/clase/do-add", data: $("#adauga").serialize(), dataType: "json", error: function (xhr, textStatus, errorThrown) { alert('Try again.'); }, success: function(data) { var dlHTML = '<dl id="' + data.id + '"> [too long] </dl>'; $('form#adauga').after(dlHTML); $('#main dl:first').hide().fadeIn(); adaugaClasaSubmit.removeAttr('disabled'); adaugaClasa.removeAttr('readonly'); adaugaClasa.val("").focus(); } });

  • FOR XML PATH Query results to file with SSIS

    - by whimsql
    In SSMS I've gotten my for xml path query written and it's beautiful. I put it in an "Execute SQL Task" in the Control Flow, set the resultset to XML. Now how to I get the results into an actual xml file that I can turn around and FTP to a third party? This should have been so easy! I would put the XML into a variable but we are looking at a HUGE file, possibly 100mb+ Do I need to use a Script Task? (I'd like to avoid that if there is another option.)

  • How to tell when my batch of EAP calls are completed?

    - by codemonkie
    This is following my question: http://stackoverflow.com/questions/2607038/c-how-to-consume-web-service-adheres-to-the-event-based-asynchronous-pattern My program is calling the DoStuffAsync() x many times in a batch, hence the callback will get invoked the same number of times upon OnComplete(). Is there a way to find out when my batch is finished such that I can generate a report on the success/failed results? All I can think of is to have a static count variable for x and deduct 1 every time OnComplete() is called, but its kind of silly and error prone I'm afraid. TIA.

  • Creating a Cocoa Framework

    - by David Schiefer
    Hi, I've created a working Cocoa framework which I wish to redistribute. The problem is however, it won't run outside of Xcode. I've read something about @executable_path/../Frameworks, which I did not include, because I don't know where to put it :/ Therefore I run my app in Xcode using the DYLD_FRAMEWORK_PATH variable which works fine, but only in Xcode - if I try to run it on its own it crashes straight away and says IMAGE NOT FOUND. I'm sure @executable_path/../Frameworks is what's missing, but I don't know where to put it. Could anyone help me out please? :) Thanks

  • Opening Large (24 GB) File In C

    - by zacaj
    I'm trying to read in a 24 GB XML file in C, but it won't work. I'm printing out the current position using ftell() as I read it in, but once it gets to a big enough number, it goes back to a small number and starts over, never even getting 20% through the file. I assume this is a problem with the range of the variable that's used to store the position (long), which can go up to about 4,000,000,000 according to http://msdn.microsoft.com/en-us/library/s3f49ktz%28VS.80%29.aspx, while my file is 25,000,000,000 bytes in size. A long long should work, but how would I change what my compiler(Cygwin/mingw32) uses or get it to have fopen64?

  • Can you explain what's going on in this Ruby code?

    - by samoz
    I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code. I generally do work in C, C++, or Java, so Ruby is a pretty big change for me. I'm currently stumped with the following block of code for a database migrator: def self.up create_table :entries do |t| t.string :name t.timestamps end end Where is the t variable coming from? What does it actually represent? Is it sort of like the 'i' in a for(i=0;i<5;i++) statement? Also, where is the :entries being defined at? (entries is the name of my controller, but how does this function know about that?)

  • Using Qt with custom MinGW

    - by ereOn
    Hi, I don't know if this question would fit better on superuser.com, but since it's rather compiler related, I give it a try here. I have to use Qt with a specific version of gcc (4.5). I downloaded the last official Qt release for Windows (Vista, 32 bits version) and didn't install the shipped MinGW version; I just installed the Qt libraries/binaries. In a console, when I type qmake && make, make fails, complaining that 'g++' is not recognized as an internal command. If I type g++ in the same console, I however have the following output: g++: no input files So g++ is definitely recognized. For those who may ask, both the Qt binaries directory and MinGW binaries directory are in the system PATH environment variable. What could be wrong here ?

  • Compiler error when casting to function pointer

    - by detly
    I'm writing a bootloader for the PIC32MX, using HiTech's PICC32 compiler (similar to C90). At some point I need to jump to the real main routine, so somewhere in the bootloader I have void (*user_main) (void); user_main = (void (*) (void)) 0x9D003000; user_main(); (Note that in the actual code, the function signature is typedef'd and the address is a macro.) I would rather calculate that (virtual) address from the physical address, and have something like: void (*user_main) (void); user_main = (void (*) (void)) (0x1D003000 | 0x80000000); user_main(); ...but when I try that I get a compiler error: Error #474: ; 0: no psect specified for function variable/argument allocation Have I tripped over some vagarity of C syntax here? This error doesn't reference any particular line, but if I comment out the user_main() call, it goes away. (This might be the compiler removing a redundant code branch, but the HiTech PICC32 isn't particularly smart in Lite mode, so maybe not.)

  • Can't return a String value and append it...why?

    - by squeezemylime
    I am writing an app and am having problems returning a simple string value, and I'm not sure why. The function I am using (within a file called APIManager.m) is: - (NSString*) returnVenueUrl { NSString *venueUrl = [devEnvironment stringByAppendingString:@"venue/id/"]; return venueUrl; } I can return this properly by doing this in another .m file: APIManager *apiManager = [APIManager apiManager]; NSLog(@"view venue URL is here: %@", [apiManager returnVenueUrl]); But when I go to append a variable cast as a String onto it, I get nothing.. venueURL = [apiManager returnVenueUrl]; venueURL = [venueURL stringByAppendingString:venueId]; NSLog(@"the Full Venue URL is: %", venueURL); If anyone has any advice on how to fix this, it would be much appreciated!

  • How to determine what user and group a Python script is running as?

    - by Chirael
    I have a CGI script that is getting an "IOError: [Errno 13] Permission denied" error in the stack trace in the web server's error log. As part of debugging this problem, I'd like to add a little bit of code to the script to print the user and (especially) group that the script is running as, into the error log (presumably STDERR). I know I can just print the values to sys.stderr, but how do I figure out what user and group the script is running as? (I'm particularly interested in the group, so the $USER environment variable won't help; the CGI script has the setgid bit set so it should be running as group "list" instead of the web server's "www-data" - but I need code to see if that's actually happening.)

  • Force Python to be 32 bit on OS X Lion

    - by sciencectn
    I'm trying to use CPLEX within Python on Mac OS 10.7.5. CPLEX appears to only support a 32 bit python. I'm using this in a python shell to check if it's 32 bit: import sys,platform; print platform.architecture()[0], sys.maxsize > 2**32 I've tried these 2 commands as suggested in man 1 python, but neither seem to force 32 bit: export VERSIONER_PYTHON_PREFER_32_BIT=yes defaults write com.apple.versioner.python Prefer-32-Bit -bool yes The only thing that seems to work is this: arch -i386 python However, if I run a script using arch which calls other scripts, they all seem to start up in 64 bit mode. Is there another system wide variable to force it into 32 bit mode?

  • performing a javascript event without triggering that event handler

    - by bento
    In my latest code, I have an event handler for a focus on a textarea. When the user clicks on the textarea, that event-handler is triggered which sets some other DOM states based on the selected textarea. However, elsewhere in my program I want to programmatically set the focus of the textarea without triggering that event handler. I know Backbone, for instance, has a way to silently perform an action. My only pseudo-solution is to temporarily set a variable: var silence = true; And then, in my event handler, only perform the logic if silence is false. The handler is still triggered, but the logic doesn't run. Does anyone else know of better strategies for this?

  • converting string to int in C++

    I am trying to convert a string I read in from a file to an int value so I can store it in an integer variable. This is what my code looks like: ifstream sin; sin.open("movie_output.txt"); string line; getline(sin,line); myMovie.setYear(atoi(line)); Over here, setYear is a mutator in the Movie class (myMovie is an object of Movie class) that looks like this: void Movie::setYear(unsigned int year) { year_ = year; } When I run the code, I get the following error: error C2664: 'atoi' : cannot convert parameter 1 from 'std::string' to 'const char *' 1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
