  • defining information out of class

    - by calccrypto
    is there a way to define a value within a class in the __init__ part, send it to some variable outside of the class without calling another function within the class? like class c: def __init__(self, a): self.a = a b = 4 # do something like this so that outside of class c, # b is set to 4 automatically when i use class c def function(self): ... # whatever. this doesnt matter i have multiple classes that have different values for b. i could just make a list that tells the computer to change b, but i would rather set b within each class

  • php database session handling problem in IE8!

    - by psyb0rg
    I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

  • Question about variable definitions in functions.

    - by Kaan Tekelioglu
    Hi. #include <stdio.h> main() { int a; for(a=1; a<=4 && printf("%d ",a); a++) { int a; static int b=a; printf("%d ",(a++)-b); } getchar(); getchar(); } In this code, the printout is 1 0 2 1 3 2 4 3. I understand why the int a; part works differently then the int a which was defined outside the for function, and why static int b; is only defined once with the primary value of a ; but why does the (a++) part in printf affect proceeding values of a? Don't we redefine int a; each time the for function runs? Thanks in advance.

  • Using $.getJSON to perform cross domain request problem.

    - by Ahmed
    I'm using the following code to make cross domain request using $.getJSON, request completed but with errors, I cannot exactly detect what is the thrown error. Based on callback param of request value I route it to a certain method which retrieves required JSON data. $.getJSON("http://wthsrvr:45452/Handler.ashx/?Callback=DocumentReadStatus", { userID: vuserID, documentID: vdocumentID, format: "json" }, function(result) { if (result.readStatus == '1') { alert("ACCEPTED"); } else if (result.readStatus == '0') { alert("NOT ACCEPTED"); } else { alert(result.readStatus); } }); FYI: while development of this locally, everything worked fine, but after solution deployment to server and trying to do the same, I got that problem. Also, I tried the same functionality with web service, I got the same problem while calling web service from server. I'm using ajaxSetup to detect thrown errors. $.ajaxSetup({ "error": function(XMLHttpRequest, textStatus, errorThrown) { alert("textStatus: " + textStatus); alert("errorThrown: " + errorThrown); alert("responseText: " + XMLHttpRequest.responseText); } });

  • option & jQuery .click() won't work together

    - by meow
    Hello, this works great in FF but not in IE, Chrome or Safari. $('#countryDropDown option').click(function() { var countryID = $(this).val(); dostuff(); }); // countryDropDown = id of select So, as you can see I want to attach a click event to each option. I alos tried var allOpts = $('#countryDropDown option'), l = allOpts.length, i = 0; for (i = 0; i < l; i += 1) { $(allOpts[i]).click(function() { var countryID = $(this).val(); doStuff(); }); } It still does not want to work in any other browser but FF. What am I doing wrong? Thanks

  • Algorithm Question Maximize Average of Functions

    - by paradoxperfect
    Hello, I have a set of N functions each denoted by Fi(h). Each function returns some value when given an h. I'm trying to figure out a way to maximize the average of all of the functions given some total H value. For example, say each function represents a grade on an assignment. If I spend h hours on assignment i, I will get g = Fi(h) as my grade. I'm given H hours to finish all of the assignments. I want to maximize my average grade for all assignments. Can anyone point me in the right direction to figure this out?

  • How do I make different texts to appear in after clicking x-times?

    - by Sebastian Lindén
    I want to show some text within a class for each click but keep the clicky-class. Shortly, if you click 2 times, you will get a div-text "You clicked two times", you will still be able to click a third time, then you will get "You clicked three times", until the fifth time when everything will hide. Is there any simpel way to do this? I tried with this but couldn't get it to work. var clicks = 0; $('.clicky').on('click', function() { clicks++; if(clicks >= 3) { $(this).add($('.background')).add($('.hello')); } else(clicks >= 5) { $(this).add($('.background')).hide(); } });? http://jsfiddle.net/sLAzY/ This is a working example of the hide function. Hope you understand what I mean Have a nice day!

  • Perfect Forwarding to async lambda

    - by Alexander Kondratskiy
    I have a function template, where I want to do perfect forwarding into a lambda that I run on another thread. Here is a minimal test case which you can directly compile: #include <thread> #include <future> #include <utility> #include <iostream> #include <vector> /** * Function template that does perfect forwarding to a lambda inside an * async call (or at least tries to). I want both instantiations of the * function to work (one for lvalue references T&, and rvalue reference T&&). * However, I cannot get the code to compile when calling it with an lvalue. * See main() below. */ template <typename T> std::string accessValueAsync(T&& obj) { std::future<std::string> fut = std::async(std::launch::async, [](T&& vec) mutable { return vec[0]; }, std::forward<T>(obj)); return fut.get(); } int main(int argc, char const *argv[]) { std::vector<std::string> lvalue{"Testing"}; // calling with what I assume is an lvalue reference does NOT compile std::cout << accessValueAsync(lvalue) << std::endl; // calling with rvalue reference compiles std::cout << accessValueAsync(std::move(lvalue)) << std::endl; // I want both to compile. return 0; } For the non-compiling case, here is the last line of the error message which is intelligible: main.cpp|13 col 29| note: no known conversion for argument 1 from ‘std::vector<std::basic_string<char> >’ to ‘std::vector<std::basic_string<char> >&’ I have a feeling it may have something to do with how T&& is deduced, but I can't pinpoint the exact point of failure and fix it. Any suggestions? Thank you! EDIT: I am using gcc 4.7.0 just in case this could be a compiler issue (probably not)

  • Question regarding Ajax Hacking

    - by Vincent
    All, I have a PHP website written in Zend Framework and MVC. Most of the controller actions check if the request is an Ajax request or not, else they redirect the user to home page. I am thinking about various ways to break that site. I am considering the following scenario: A user creates his own PHP project on his Local machine. User writes a JQuery ajax post request to one of the controllers on my site and tries to post malicious info. Ex: $.ajax({ type: 'POST', url: "https://marketsite/getinfo/getstuff", cache: false, dataType: "html", success: function(html_response){ alert(html_response); }, error: function(xhr,ajaxOptions,errorThrown){ alert(errorThrown); } }); My Question is does "url" attribute in the ajax request above take absolute path? I know it takes relative path. Also, is it possible to break any site by sending such requests? Thanks

  • exportDocument() 'destination folder does not exist' error

    - by dvb
    I'm trying to make a script in photoshop that will modify some layers and than export them as a PNG image. I've copied the following code from another place: function SavePNG(saveFile){ var pngOpts = new ExportOptionsSaveForWeb; pngOpts.format = SaveDocumentType.PNG pngOpts.PNG8 = false; pngOpts.transparency = true; pngOpts.interlaced = true; pngOpts.quality = 100; activeDocument.exportDocument(saveFile,ExportType.SAVEFORWEB,pngOpts); } The function export the active document of photoshop to the file specified by the saveFile parameter. It's working fine with simple paths like 'C:\images\result.png' but when trying with different paths like '~/Desktop/' or paths with some special characters the file isn't exported, and a 'destination folder does not exist' error massage appear. Any idea how can I solve it?

  • Always require a plugin to be loaded

    - by axon
    I am writing an application with RequireJS and Knockout JS. The application includes an extension to knockout that adds ko.protectedObservable to the main knockout object. I would like this to always be available on the require'd knockout object, and not only when I specify it in the dependencies. I could concat the files together, but that seems that it should be unnecessary. Additionally, I can put knockout-protectedObservable as a dependency for knockout in the requirejs shim configuration, but that just leads to a circular dependency and it all fails to load. Edit: I've solved me issue, but seems hacky, is there a better way? -- Main.html <script type="text/javascript" src="require.js"></script> <script type="text/javascript"> require(['knockout'], function(ko) { require(['knockout-protectedObservable']); }); </script> -- knockout-protectedObservable.js define(['knockout'], function(ko) { ko.protectedObservable = { ... }; });

  • strcmp equivelant for integers (intcmp) in PHP

    - by Chase
    So we got this function in PHP strcmp(string $1,string $2) // returns -1,0, or 1; We Do not however, have an intcmp(); So i created one: function intcmp($a,$b) { if((int)$a == (int)$b)return 0; if((int)$a > (int)$b)return 1; if((int)$a < (int)$b)return -1; } This just feels dirty. What do you all think?

  • Is calling of overload operator-> resolved at compile time?

    - by Brent

I'd added "-S" option for compile only.

  • Variable scope in javascript

    - by Rich Bradshaw
    This is a simple question, but I can't work it out. The specifics aren't important, but here's the gist. I have some code like this: var lat = 0; var lon = 0; if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { lat = position.coords.latitude; lon = position.coords.longitude; }); } What I think it's doing is: Set lat and lon to 0 If the browser has geolocation, overwrite those variables with real values However, at the end of that chunk, lat and lon are still 0. I've tried adding vars, passing lat and lon to the function etc but with no success... How do I make this work?

  • how to handle exceptions/errors in php?

    - by fayer
    when using 3rd part libraries they tend to throw exceptions to the browser and hence kill the script. eg. if im using doctrine and insert a duplicate record to the database it will throw an exception. i wonder, what is best practice for handling these exceptions. should i always do a try...catch? but doesn't that mean that i will have try...catch all over the script and for every single function/class i use? Or is it just for debugging? i don't quite get the picture. Cause if a record already exists in a database, i want to tell the user "Record already exists". And if i code a library or a function, should i always use "throw new Expcetion($message, $code)" when i want to create an error? Please shed a light on how one should create/handle exceptions/errors. Thanks
