  • sqlite ERROR no such column

    - by Richard
    Hi, Does anyone here have some experience with this error? Only If I use the WHERE clause, I get this error. I use php PDO to get the results. And this is my simple table $sql = "CREATE TABLE samenvatting ( stem_id INTEGER PRIMARY KEY AUTOINCREMENT, poll_id TEXT, stem_waarde_id TEXT, totaal INTEGER )"; $crud->rawQuery($sql); $poll_id = "somepoll"; $records = $crud->rawSelect('SELECT * FROM samenvatting WHERE poll_id=´.$poll_id); pdo abstract class public function conn() { isset($this->username); isset($this->password); if (!$this->db instanceof PDO) { $this->db = new PDO($this->dsn, $this->username, $this->password); $this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } } public function rawSelect($sql) { $this->conn(); return $this->db->query($sql); } Thanks, Richard

  • CakePHP Accessing Dynamically Created Tables?

    - by Dave
    As part of a web application users can upload files of data, which generates a new table in a dedicated MySQL database to store the data in. They can then manipulate this data in various ways. The next version of this app is being written in CakePHP, and at the moment I can't figure out how to dynamically assign these tables at runtime. I have the different database config's set up and can create the tables on data upload just fine, but once this is completed I cannot access the new table from the controller as part of the record CRUD actions for the data manipulate. I hoped that it would be along the lines of function controllerAction(){ $this->uses[] = 'newTable'; $data = $this->newTable->find('all'); //use data } But it returns the error Undefined property: ReportsController::$newTable Fatal error: Call to a member function find() on a non-object in /app/controllers/reports_controller.php on line 60 Can anyone help.

  • Regex-expression with danish characters

    - by timkl
    I'm currently trying to wrap my head around regex, I have a validation snippet that tests an input box against a regex-expression: $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z]*$/).test(value); }, "Some text"); That works well, but when I try to add a space and some special danish characters, it doesn't filter the danish characters, only the space. $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z æøåÆØÅ]*$/).test(value); }, "Some text"); Any ideas to what could be wrong?

  • Confusion regarding laziness

    - by Abhinav Kaushik
    I have a function myLength = foldl (\ x _ -> x + 1) 0 which fails with stack overflow with input around 10^6 elements (myLength [1..1000000] fails). I believe that is due to the thunk build up since when I replace foldl with foldl', it works. So far so good. But now I have another function to reverse a list : myReverse = foldl (\ acc x -> x : acc) [] which uses the lazy version foldl (instead of foldl') When I do myLength . myReverse $ [1.1000000]. This time it works fine. I fail to understand why foldl works for the later case and not for former?

  • JQuery UI Dialog query dialog DOM

    - by Travis
    The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

  • Issue with JSON and jQuery

    - by Jason N. Gaylord
    I'm calling a web service and returning the following data in JSON format: ["OrderNumber":"12345","CustomerId":"555"] In my web service success method, I'm trying to parse both: $.ajax({ type: "POST", url: "MyService.asmx/ServiceName", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { var data = msg.d; var rtn = ""; $.each(data, function(list) { rtn = rtn + this.OrderNumber + ", " + this.CustomerId + "<br/>"; } rtn = rtn + "<br/>" + data; $("#test").html(rtn); } }); but I'm getting a bunch of "undefined, undefined" rows followed by the correct JSON string. Any idea why? I've tried using the eval() method but that didn't help as I got some error message talking about ']' being expected.

  • Python lambda returning None instead of empty string

    - by yoshi
    I have the following lambda function: f = lambda x: x == None and '' or x It should return an empty string if it receives None as the argument, or the argument if it's not None. For example: >>> f(4) 4 >>> f(None) >>> If I call f(None) instead of getting an empty string I get None. I printed the type of what the function returned and I got NoneType. I was expecting string. type('') returns string, so I'd like to know why the lambda doesn't return an empty string when I pass None as an argument. I'm fairly new to lambdas so I might have misunderstood some things about how they work.

  • Rails: AJAX Controller JS not firing...

    - by neezer
    I'm having an issue with one of my controller's AJAX functionality. Here's what I have: class PhotosController < ApplicationController # ... def create @photo = Photo.new(params[:photo]) @photo.image_content_type = MIME::Types.type_for(@photo.image_file_name).to_s @photo.image_width = Paperclip::Geometry.from_file(params[:photo][:image]).width.to_i @photo.image_height = Paperclip::Geometry.from_file(params[:photo][:image]).height.to_i @photo.save! respond_to do |format| format.js end end # ... end This is called through a POST request sent by this code: $(function() { // add photos link $('a.add-photos-link').colorbox({ overlayClose: false, onComplete: function() { wire_add_photo_modal(); } }); function wire_add_photo_modal() { <% session_key = ActionController::Base.session_options[:key] %> $('#upload_photo').uploadify({ uploader: '/swf/uploadify.swf', script: '/photos', cancelImg: '/images/buttons/cancel.png', buttonText: 'Upload Photo(s)', auto: true, queueID: 'queue', fileDataName: 'photo[image]', scriptData: { '<%= session_key %>': '<%= u cookies[session_key] %>', commit: 'Adding Photo', controller: 'photos', action: 'create', '_method': 'post', 'photo[gallery_id]': $('#gallery_id').val(), 'photo[user_id]': $('#user_id').val(), authenticity_token: encodeURIComponent('<%= u form_authenticity_token if protect_against_forgery? %>') }, multi: true }); } }); Finally, I have my response code in app/views/photos/create.js.erb: alert('photo added!'); My log file shows that the request was successful (the photo was successfully uploaded), and it even says that it rendered the create action, yet I never get the alert.

  • Problems with Linked List in C

    - by seePhor
    Hey everyone, I am new to C and I am working on an XOR linked list for a project. I have most of the code done, but I can't seem to get the delete function of the list to work properly. It seems able to delete some numbers, but not any number you pass into the function. Could anyone experienced with C take a look and possibly point out where I went wrong? I have been working on this for a while now and have not had much luck and I have started over 3 times :( Any help is much appreciated. Thank you. You can see my first attempt of code here. I can only post one link, so if you would like to see my second attempt, just tell me so and I can email it to you or something. Thank you for your time.

  • Doing ajax with Jquery.

    - by user272899
    I have been loading content with ajax and all works fine. Here is my code $(document).ready(function() { //Load a-z.php //Timestamp resolves IE caching issue var tsTimeStamp= new Date().getTime(); $.post('../../includes/categories/a-z.php', {action: "post", time: tsTimeStamp}, function(data){ $('#moviescontainer').html(data).slideDown('slow'); }); return true; }); My data inside a-z.php requires Javascript for it's content and when I load a-z.php onto my page the javascript doesn't work. I am quessing that I need to link the relevant files to a-z.php and then load it via ajax. Doesn't this kind of defeat the object of ajax?? That means that I will be loading the js files on the main page and then loading them again when I ajax a-z.php I hope I made some sense.

  • More GCC link time issues: undefined reference to main

    - by vikramtheone
    Hi Guys, I'm writing software for a Cortex-A8 processor and I have to write some ARM assembly code to access specific registers. I'm making use of the gnu compilers and related tool chains, these tools are installed on the processor board(Freescale i.MX515) with Ubuntu. I make a connection to it from my host PC(Windows) using WinSCP and the PuTTY terminal. As usual I started with a simple C project having main.c and functions.s. I compile the main.c using GCC, assemble the functions.s using as and link the generated object files using once again GCC, but I get strange errors during this process. An important finding - Meanwhile, I found out that my assembly code may have some issues because when I individually assemble it using the command as -o functions.o functions.s and try running the generated functions.o using ./functions.o command, the bash shell is failing to recognize this file as an executable(on pressing tab functions.o is not getting selected/PuTTY is not highlighting the file). Can anyone suggest whats happening here? Are there any specific options I have to send, to GCC during the linking process? The errors I see are strange and beyond my understanding, I don't understand to what the GCC is referring. I'm pasting here the contents of main.c, functions.s, the Makefile and the list of errors. Help, please!!! Vikram main.c #include <stdio.h> #include <stdlib.h> int main(void) { puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */ return EXIT_SUCCESS; } functions.s * Main program */ .equ STACK_TOP, 0x20000800 .text .global _start .syntax unified _start: .word STACK_TOP, start .type start, function start: movs r0, #10 movs r1, #0 .end Makefile all: hello hello: main.o functions.o gcc -o main.o functions.o main.o: main.c gcc -c -mcpu=cortex-a8 main.c functions.o: functions.s as -mcpu=cortex-a8 -o functions.o functions.s Errors ubuntu@ubuntu-desktop:~/Documents/Project/Others/helloworld$ make gcc -c -mcpu=cortex-a8 main.c as -mcpu=cortex-a8 -o functions.o functions.s gcc -o main.o functions.o functions.o: In function `_start': (.text+0x0): multiple definition of `_start' /usr/lib/gcc/arm-linux-gnueabi/4.3.3/../../../crt1.o:init.c:(.text+0x0): first defined here /usr/lib/gcc/arm-linux-gnueabi/4.3.3/../../../crt1.o: In function `_start': init.c:(.text+0x30): undefined reference to `main' collect2: ld returned 1 exit status make: *** [hello] Error 1

  • Can't access dojo object property using string variable

    - by Kareem
    I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

  • Idiomatic usage of filter, map, build-list and local functions in Racket/Scheme?

    - by Greenhorn
    I'm working through Exercise 21.2.3 of HtDP on my own and was wondering if this is idiomatic usage of the various functions. This is what I have so far: (define-struct ir (name price)) (define list-of-toys (list (make-ir 'doll 10) (make-ir 'robot 15) (make-ir 'ty 21) (make-ir 'cube 9))) ;; helper function (define (price< p toy) (cond [(< (ir-price toy) p) toy] [else empty])) (define (eliminate-exp ua lot) (cond [(empty? lot) empty] [else (filter ir? (map price< (build-list (length lot) (local ((define (f x) ua)) f)) lot))])) To my novice eyes, that seems pretty ugly because I have to define a local function to get build-list to work, since map requires two lists of equal length. Can this be improved for readability? Thank you.

  • Jquery - effect + autohide

    - by lidermin
    Hello, I'm using jquery to animate a bit my web site, but I'm having a little issue with some behaviour: I have a div, which suddenly appears from the top of the page and shakes: $(minipopup).animate({ marginTop: '+=' + (240) + 'px' }, 1000); $(minipopup).effect("shake"); This mini popup has an X for closing it, or else, it will auto close after a few seconds: setTimeout(function() { $('#minipopup').effect("explode"); }, 10000); $('#closePopup').click(function() { $('#minipopup').effect("explode"); }); Everything works, except that, if the user clicks the CLOSE button, he sees the explode effect and the popup effectively dissapears, but after the 10 seconds pass (the one I defined under the setTimeout), the user again sees the popup explosion (just the effect, cause the popup is not there visually). How could I avoid that "ghost" explosion if the user already closed the popup manually? Thanks in advance.

  • Parsing Serialized JSON DataSet using Jquery

    - by Zachary Carter
    Hello all, and thanks for reading. I wrote a web service which is called through jsonp, and returns a .Net 3.5 DataSet which I then want to parse using jquery. It appears that the getJson() method is working fine as far as parsing the json goes. The following request - $.getJSON("http://localhost:80/ws.asmx/Example?format=json&callback=?", function(data) { alert(data.d); }); results in - {"Tables": [ { "Rows": [ { "CASE_TYP_CD": "M", "CASE_TYP_DESC": "MOVING VIOLATION", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }, { "CASE_TYP_CD": "T", "CASE_TYP_DESC": "TRUANCY/FAILURE TO ATTEND SCHOOL", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }, { "CASE_TYP_CD": "J", "CASE_TYP_DESC": "JUVENILE", "AUTO_GENERATE": "Y", "CONFIDENTIAL_FLG": "N" }... Well I'm kind of new at this whole json thing and I can't figure out how to gain access to the values held in the nodes. I was thinking it would be something like - $.each("CASE_TYP_CD", function() { //code goes here }); But that doesn't seem to be working. Could anyone help me out with this? Thanks in advance!

  • How do you draw a line from one corner of the stage to the other?

    - by George Edison
    I am completely perplexed. I asked this question and it (any mentioned solution) doesn't seem to be working at all. All I want is to draw a line from one corner to the other. Here again is the link to the SWF file I have (it's embedded in an HTML document): test.html Here is the source: package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point graphics.clear(); graphics.lineStyle(10, 0x000000); graphics.moveTo(0, 0); graphics.lineTo(stage.stageWidth, stage.stageHeight); } } } It just doesn't work! The line goes from somewhere offscreen to about the middle of the stage. What on earth am I doing wrong?

  • Assignment to None

    - by Joel
    Hello, I have a function which returns 3 numbers, e.g.: def numbers(): return 1,2,3 usually I call this function to receive all three returned numbers e.g.: a,b,c=numbers() However, I have one case in which I only need the first returned number. I tried using: a, None None = numbers() But I receive "SyntaxError: assignment to None". I know, of course, that i can use the first option I mentioned and then not use "b" and "c", but only "a". However, this seems like a "waste" of two vars and feels like wrong programming. Any ideas? Thanks, Joek

  • Flash AS3 - Display an error if the XML if incorrect

    - by ongoingworlds
    Hi, I'm creating a flash application which loads in some XML which is generated dynamically from the CMS. I want to display an error in case the XML file isn't formatted correctly. When I test this with incorrectly formatted XML, it will just get to the line myXML = XML(myLoader.data); and then just bomb out. How can I catch the error, display a message to the user, but the flash program to continue as normal. var myXMLURL:URLRequest = new URLRequest(XMLfile); var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener(Event.COMPLETE, xmlLoaded); myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlFailed); var myXML:XML; //--when the xml is loaded, do this function xmlLoaded(e:Event):void { myXML = XML(myLoader.data); trace("XML = "+myXML); } //--if the xml fails to load, do this function xmlFailed(event:IOErrorEvent):void { errorMsg.text = "The XML file cannot be found" }

  • Virtual class problem

    - by ugur
    What i think about virtual class is, if a derived class has a public base, let's say, class base, then a pointer to derived can be assigned to a variable of type pointer to base without use of any explicit type conversion. But what if, we are inside of base class then how can we call derived class's functions. I will give an example: class Graph{ public: Graph(string); virtual bool addEdge(string,string); } class Direct:public Graph{ public: Direct(string); bool addEdge(string,string); } Direct::Direct(string filename):Graph(filename){}; When i call constructor of Direct class then it calls Graph. Now lets think Graph function calls addedge. Graph(string str){ addedge(str,str); } When it calls addedge, even if the function is virtual, it calls Graph::edge. What i want is, to call Direct::addedge. How can it be done?
