• format - Help with printing a table

  - by Michael Kohl

  This question will probably end in a facepalm, but I've tried for a while and am still stuck despite reading through the hyperspec. Basically what I want to do is something like (format t "~{|~{ ~5d~}|~%~}" '((1 23 2 312) (23 456 1 7890))) but instead of hard-coding the 5 it should be calculated from the list (length of longest element from any nested list + 1) to give something like | 1 23 2 312| | 23 456 1 7890| Maybe I'm thinking way too complicated here and there is an easier way to do what I want, but I think I ran myself into a mental corner that I can't get out of.

• Help me refactor this nasty Ruby if/else statement

  - by Suborx

  Hello, so I have this big method in my application for newsletter distribution. Method is for updating rayons and I need to assign a user to rayon. I have relation n:n through table colporteur_in_rayons which has attributes since_date and until_date. I am a junior programmer and I know this code is pretty dummy :) I appreciate every suggestion. def update rayon = Rayon.find(params[:id]) if rayon.update_attributes(params[:rayon]) if params[:user_id] != "" unless rayon.users.empty? unless rayon.users.last.id.eql?(params[:user_id]) rayon.colporteur_in_rayons.last.update_attributes(:until_date => Time.now) Rayon.assign_user(rayon.id,params[:user_id]) flash[:success] = "Rayon #{rayon.name} has been succesuly assigned to #{rayon.actual_user.name}." return redirect_to rayons_path end else Rayon.assign_user(rayon.id,params[:user_id]) flash[:success] = "Rayon #{rayon.name} has been successfully assigned to #{rayon.actual_user.name}." return redirect_to rayons_path end end flash[:success] = "Rayon has been successfully updated." return redirect_to rayons_path else flash[:error] = "Rayon has not been updated." return redirect_to :back end end

• Appending html code to a section inside a dialog window isn't working in IE6

  - by user338413

  I'm using jQuery's validation on a form. When the form is validated, I'm using a submitHandler to fill a dialog with data from the form then I open the dialog to display it. Works great except for in IE6. Nothing displays. I've tried initializing the dialog before and after running the validation code but neither makes a difference. Here's the validation code: $("#acct").validate({ ... submitHandler: function() { fillVerificationDialog(); $("#verification_dialog").dialog('open'); return false; } }); Here's the fillVerificationDialog: function fillVerificationDialog() { $("#dialog-data").empty(); $("<span class='label'>").text("First Name: ").appendTo("#dialog-data"); $("<span class='value'>").text($("#firstname").val()).appendTo("#dialog-data"); $("<br/>").appendTo("#dialog-data"); ... }

• HTML input text box vs CakePHP Automagic Form Elements

  - by kwokwai

  Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

  - by Scarface

  Hey guys, I have never installed an extension before so I am not really sure where to start. I want to do 2 things: install clamav virus scanner http://sourceforge.net/projects/php-clamav/ on my remote server which is a linux apache setup using cpanel as a gui. install clamav on my localserver on my home computer which operates on windows and has WAMP server installed for server-side activity What is the difference between the two installation methods? What is required for each installation? If anyone can point me in the right direction in any way, I would really appreciate it. Even if it is just an article or tutorial on how to get started.

• parsing through html with php

  - by salmane

  while working on facebook connect I have to retrieve an access token from a url ( it is not in the url itself but in the file lined to that url) so this is what I do $url = "https://graph.facebook.com/oauth/access_token?client_id=".$facebook_app_id."&redirect_uri=http://www.example.com/facebook/oauth/&client_secret=".$facebook_secret."&code=".$code;" function get_string_between($string, $start, $end){ $string = " ".$string; $ini = strpos($string,$start); if ($ini == 0) return ""; $ini += strlen($start); $len = strpos($string,$end,$ini) - $ini; return substr($string,$ini,$len); } $access_token = get_string_between(file_get_contents($url), "access_token=", "&expires="); it looks ugly and clumsy is there a better way to do it ? thank you .

• JNA Passing Structure By Reference Help

  - by tyeh26

  Hi all, I'm trying to use JNA to talk over a USB device plugged into the computer. Using Java and a .dll that was provided to me. I am having trouble with the Write function: C code: typedef struct { unsigned int id; unsigned int timestamp; unsigned char flags; unsigned char len; unsigned char data[16]; } CANMsg; CAN_STATUS canplus_Write( CANHANDLE handle, //long CANMsg *msg ); Java Equivalent: public class CANMsg extends Structure{ public int id = 0; public int timestamp = 0; public byte flags = 0; public byte len = 8; public byte data[] = new byte[16]; } int canplus_Write(NativeLong handle, CANMsg msg); I have confirmed that I can open and close the device. The close requires the NativeLong handle, so i am assuming that the CANMsg msg is the issue here. I have also confirmed that the device works when tested with C only code. I have read the the JNA documentation thoroughly... I think. Any pointers. Thanks all.

• Need help setting up json array

  - by torr

  A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?
