sql select with php variable

- by user1572526

I'm trying to print out a html-table from db-table 'dimensions'. I only want dimensions from the selected pipetype which I get from a dropdownbox. For now I just put in "Steel" manually. Steel has pipe_id = 2 in db-table 'pipes'. I've run the first query in my db-tool and it returns 2 so there's nothing wrong there. The second query returns nothing. But when I manually set $wq = 2 (which I comment out below) it prints out the html-table perfectly. What am I doing wrong here? $wq="SELECT pipe_id FROM pipes WHERE title_en = 'Steel'"; //$wq = '2'; $sql="SELECT * FROM dimensions WHERE pipe_id = '".$wq."'";

Jquery Click in li

- by cKendrick

I have my html set up like this: <li> Header <button>Edit</button> </li> And I was wondering if there is a way so that you can click on the li and have one action happen and click on the button and have another action happen. Right now if I have a jquery click element on the li it gets fired when you hit the button to. Is there a way to make this separate without changing the html structure?

Serialize JavaScript's navigator object

- by kappa

Hi, I'm creating a page to help diagnose the problem our users are experiencing with our web pages (you know, asking a user "What browser are you using?" usually leads to "Internet"). This page already submits to me all the HTTP headers and now I'm trying to have JavaScript give some more informations, so I thought it would be great to have the user's navigator JavaScript object and I started looking how to serialize it so I can submit it through a form. The problem is I'm not able to serialize the navigator object using any JSON library I know of, everyone returns an empty object (?!), so I decided to write an ad-hoc serializer. You can find the code here: <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function serialize (object) { var type = typeof object; if (object === null) { return '"nullValue"'; } if (type == 'string' || type === 'number' || type === 'boolean') { return '"' + object + '"'; } else if (type === 'function') { return '"functionValue"'; } else if (type === 'object') { var output = '{'; for (var item in object) { if (item !== 'enabledPlugin') { output += '"' + item + '":' + serialize(object[item]) + ','; } } return output.replace(/\,$/, '') + '}'; } else if (type === 'undefined') { return '"undefinedError"'; } else { return '"unknownTypeError"'; } }; $(document).ready(function () { $('#navigator').text(serialize(navigator)); }); </script> <style type="text/css"> #navigator { font-family: monospaced; } </style> <title>Serialize</title> </head> <body> <h1>Serialize</h1> <p id="navigator"></p> </body> </html> This code seems to work perfectly in Firefox, Opera, Chrome and Safari but (obviously) doesn't work in Internet Explorer (at least version 8.0), it complains that "Property or method not supported by the object" at line for (var item in object) {. Do you have any hint on how to fix the code or how to reach the goal (serialize the navigator object) by other means?

C# ComboBox SelectedItem [closed]

- by Diane

I have a combobox with a list of values. I would like the selected index to be a value from the database. I first create the combobox, fill it with values from a dataset like this: ComboBox cmb_Relay = new ComboBox(); cmb_Relay.DataSource = ds2.Tables[0]; cmb_Relay.DisplayMember = "Relay"; cmb_Relay.ValueMember = "Relay"; Next, I set the SelectedIndex to the value of a specific field value: cmb_Relay.SelectedItem = ds2.Tables[0].Rows[j][2]; I get the follwing error: InvalidArgument=Value of '3' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex

How to embed a web browser control in a cross-platform application?

- by Gil

hi, I need to write quickly this application: a simple window that wraps a web browser control, that runs html pages. The Browser UI (e.g. Navigation buttons) should be suppressed. As a .net developer, I would embed the WebBrowser OCX in a Windows Form. But this has to run on Mac as well!! I found the following cross-platform candidates. Which one would you choose (in terms of simplicity, stableness, community support, etc.): 1) wxWidgets (www.kirix.com/labs/wxwebconnect.html) 2) QT: www.youtube.com/watch?v=Ee8eRwjbcFk&feature=related 3) MONO: www.mono-project.com/WebBrowser Thanks!

How to get parameters out of an ascx back to the main aspx page

- by Hallaghan

I've got an aspx page that renders an ascx page with filtering capabilities. Inside the ascx page, parameters are passed as follows: <tr> <td class="label">Plataforma</td> <td class="field lookup"><%= Html.Lookup("s.Site", null, Url, "Sites") %></td> </tr> <tr> <td class="label">Data</td> <td class="field date"><%= Html.TextBox("s.Date", DateTime.Today.ToString("yyyy-MM-dd")) %></td> </tr> I need to be able to get those parameters on the main aspx page, because they are needed for an action that is called there. How could I access these parameters?

HTML5 Canvas compositing question (source-in)

- by Alex Ciarlillo

I am trying to recreate a page flipping type animation in HTML5 using canvas. The animation is based on ideas from here: hxxp://oreilly.com/javascript/archive/flashhacks.html but thats not really important. The problem I am having is that using the 'source-in' composite operation is not giving me the results I expect and would like clarification as to why. Here is the example: (i think it can only be viewed in chrome, not working in FF 3.6) http://acpound.fylez.com/test/example.html The black rectangle is supposed to act as a 'mask' for the page being turned over. All I want to see is the turning page in the areas where it overlaps the mask. The problem is the entire black rectangle is drawn, not just the area where they overlap. The source is all on the page. I know HTML5 isn't really being used yet, I'm just experimenting for my personal site and curiosity. Any ideas would be greatly appreciated.

Best way to implement nested loops in a view in asp.net mvc 2

- by Junior Ewing

Hi, Trying to implement some nested loops that are spitting out good old nested html table data. So the question is; What is the best way to loop through lists and nested lists in order to produce easily maintainable code. It can get quite narly quite fast when working with multiple nested tables or lists. Should I make use of a HTML helper, or make something with the ViewModel to simplify this? A requirement is if there are no children at a node there should be an empty row on that spot with some links for creation and into other parts of the system.

Getting search results from Twitter in php

- by Mark Mayo

I'm attempting to put together a little mashup with some twitter APIs. However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken. Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term. Followed the tutorial to the letter at http://www.reynoldsftw.com/2009/02/using-jquery-php-ajax-with-the-twitter-api/ and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there. I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now.

Saving full page content using Selenium

- by Rick

Hi all, I was wondering what's the best way to save all the files that are retrieved when Selenium visits a site. In other words, when Selenium visits http://www.google.com I want to save the HTML, JavaScript (including scripts referenced in src tags), images, and potentially content contained in iframes. How can this be done? I know getHTMLSource() will return the HTML content in the body of the main frame, but how can this be extended to download the complete set of files necessary to render that page again. Thanks in advance!

Boost::asio bug in MSVC10 - Failing BOOST_WORKAROUND in ~buffer_debug_check() in buffer.hpp

- by shaz

A straight compilation of example http://www.boost.org/doc/libs/1_43_0/doc/html/boost_asio/tutorial/tutdaytime3/src.html results in a runtime null pointer exception. Stack trace points to the buffer_debug_check destructor which contains this comment: // MSVC's string iterator checking may crash in a std::string::iterator // object's destructor when the iterator points to an already-destroyed // std::string object, unless the iterator is cleared first. The test #if BOOST_WORKAROUND(BOOST_MSVC, = 1400) succeeds in MSVC10 and (but) results in a null pointer exception in c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\xutility line 123 _Iterator_base12& operator=(const _Iterator_base12& _Right) { // assign an iterator if (_Myproxy != _Right._Myproxy) _Adopt(_Right._Myproxy->_Mycont); return (*this); } _Right._Myproxy is NULL

any way to use ajax with jstl customtags without duplicating tags in javascript?

- by CodeMonkeyB

I am working on a page where part of the content is loaded normally and the pages are rendered using jsps. The product images and links generated on that page are by custom jstl tags. When the user scrolls more products are requested from the server in a JSON response and then using UnderscoreJS templates they are rendered and added to the bottom of the page. Is there any way I can use the JSTL tags in Javascript without recreating them using a javascript function (it won't be possible to re-create all of them in javascript). What is the best way to handle this scenario? I guess I could return a rendered html response for the ajax call, but that would mean I have some ajax requests which use json and some that use rendered html...

Why jQuery selector can't work but getElementById works in this scenario?

- by Stallman

Here is the HTML: <html> <head> <script type="text/javascript" src="jquery-1.7.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="jquery-1.7.2.js"></script> <script type="text/javascript" src="access.js"></script> </head> <body> <button id="trigger"></button> <img id= "testElement" style= "position: absolute; border-color: white; top:340px; left:615px;" width="34px" height= "34px" /> </body> </html> And the access.js file is: $(document).ready( function(){ $('#trigger').click(function(){ $('#testElement').src="success.png"; //THIS WON'T WORK. document.getElementById('testElement').src= "success.png"; //BUT THIS WORKS. }); }); I know that if I use $, the return object is a jQuery object. It's not the same as getElementById. But why the jQuery selector can't work here? I need the jQuery object to make more operations like "append/style"... Thanks. UPDATE Too much correct answers appear at almost the same time... Please give more explanations to let me decide who I should give the credit, thanks!!! Sorry for my poor understanding of your correct answer... I just want more detail. Are all the attribute nodes(src/width/height...) not the property of jQuery object? So does the jQuery selector only select DOM Element Node like ? Thank you! 3. List item

Where does ASP.Net get its rendered IDs from?

- by NeilD

Hi, I've inherited a project with some nasty JavaScript that depends on hard coded object ids. i.e. There are lots of places where it does things like this var magazine = document.getElementById('repModuleDisplay__ctl3_chkCats_0'); When the page renders in my UAT environment, the HTML looks like this, and everything works OK. <input id="repModuleDisplay__ctl3_chkCats_0" type="checkbox" name="repModuleDisplay:_ctl3:chkCats:0" ... etc However, when I put it on my Production environment, the HTML is suddenly rending like this: <input id="repModuleDisplay_ctl03_chkCats_0" type="checkbox" name="repModuleDisplay$ctl03$chkCats$0" ... etc The difference in ids means that the JavaScript can't find the Element, and fails. In an ideal world, I'd scrap the buggy JavaScript and do it again properly, but for a quick fix, I'd like to know what is causing the difference in rendering between the two environments. Does anyone have any ideas? Thanks, Neil

Passing arguments from loading activity to main activity

- by ZelluX

I'm writing an application that starts with a loading activity. In the loading activity the app requests html from web and parses the html, then it sends the parsing result to the main activity. The main activity has several tabs, and contents of these tabs are based on the result of parsing. For example, the result of parsing is a list of strings ["apple", "banana", "orange"], and I need to pass this list to main activity, so that the main activity can create three tabs named after three fruits. I would like to know if there is any way to pass a list of strings among activities, BTW, is it the common way of do this? Many thanks.

how to pass in a reference to a string in javascript?

- by ijjo

maybe a closure is my solution? not exactly sure how to pull it off though. the code is set up like so: var globalVar = ''; var globalVar2 = ''; function func() { if (condition) func2(globalVar) else func2(globalVar2) } in func2() i cache some HTML in a main container into the appropriate global variable that i pass to it. basically i have a main container that holds different pages depending on what tab they choose. for performance i want to cache the page into global vars so i need to know what tab is active to figure out which global var to assign the html to.

ajax Post data missing with tinyMCE on Firefox

- by Freeman

I have a problem with my form when I try to submit with ajax. I am using Malsup Form plugin for Jquery but also using tinyMCE editor. When I submit the form and check the $_POST array, there is no data from the textarea. I have tried to use the triggerSave() function but to no avail. Everything is working well in IE. // These options are common and will be used for many form submissions var options = { target: '#notice', // target element(s) to be updated with server response dataType:'html', resetForm:true, beforeSubmit: function(){tinyMCE.triggerSave(false,true); }, success:function(msg){ $('#notice').html( msg) refresh(3) } }; //prepare form $('#savetext').ajaxForm(options);

Develop for Desktop and Mobile at once

- by Hola Soy Edu Feliz Navidad

I need to develop a programm that is going to read some information from a special USB device and access information via Web Socket (socket.io preferred). My client wants to deploy this app on Mac OS X, Windows, Android and iOS. I was looking for development softwares valid for both: Desktop and Mobile, but it is still not clear for me and that´s what I found. Unity - Looks very good but to create a native plugin for reading from the device it lloks like I need the PRO edition. Adobe Air - Looks good but I´m not sure if I can write Native Plugins for all wanted platforms. LiveCode - Still inmature (lots of bugs) and I don´t know if it is possible to write native plugins for my device. Is there any other good platform for my case? What´s your option?

Cannot boot from Ubuntu Live CD on preinstalled Windows 8 laptop

- by seferov

I bought a Sony Vaio with Windows 8 yesterday. I want to install Ubuntu, (latest version), alongside Windows. There is an assist button on the laptop to enter the boot option menu, (otherwise, Windows 8 is booted by default. Whenever I choose the, 'boot from CD' option, it says 'No operating system found'. CD is valid since I tried it on another computer and it worked fine. I have tried both versions, 12.04 and 12.10. What is the problem, or how should I install Ubuntu on my laptop?

Error creating an .img file from an .ISO (MD5 verified)

- by Rob

I was following the instructions on this website to create a bootable USB flash drive on a Mac: http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx The instruction: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso does not create a valid file that the disk utility can copy to the USB drive, making installation on a USB drive useless. I've been repeating these instructions for days with no luck. The only thing that does not work is the .ISO to .IMG conversion. Is there a way to download Ubuntu 12.04 LTS 64-but Desktop in a .IMG file already? Unfortunately, my install notebook does not have an optical drive so USB is the only way. Thanks for your help!

Django i18n: makemessages only on site level possible?

- by AndiDog

I have several strings in my site that don't belong to any app, for example {% block title %}{% trans "Login" %}{% endblock %} or a modified authentication form used to set the locale cookie class AuthenticationFormWithLocaleOption(AuthenticationForm): locale = forms.ChoiceField(choices = settings.LANGUAGES, required = False, initial = preselectedLocale, label = _("Locale/language")) Now when I execute django-admin.py makemessages --all -e .html,.template in the site directory, it extracts the strings from all Python, .html and .template files, including those in my apps. That is because I develop my apps inside that directory: Directory structure: sitename myapp1 myapp2 Is there any way to extract all strings that are not in my apps? The only solution I found is to move the app directories outside the site directory structure, but I'm using bzr-externals (similar to git submodules or svn externals) so that doesn't make sense in my case. Moving stuff that needs translation into a new app is also possible but I don't know if that is the only reasonable solution.

which MVC for coldfusion?

- by mrjayviper

newbie to MVC here. so please be gentle. I want to move one of our existing apps (currently located in http://www.companywebsitegoeshere.com/myapp1) to MVC. As can be seen in the URL, there are many apps running in the website which I intend to move at some stage. I don't have write access to the wwwroot (/var/www/html in my case) and the webserver is used by multiple developers across the company. I'm hoping I can have the MVC framework core files/folders + my app all located in in 1 subfolder. In the case of myapp1, all the filers and folders will be inside /var/www/html/myapp1 subfolder. Can you please point me to the right direction (links/guides/docs/videos/etc)? I've looked at several like cfwheels/mach-ii/fw1 but they seemed requires wwwroot access. Thanks! :)
