Jquery table filter
|
<p>I am trying to filter table results from Table B by clicking on a field in Table A using jquery. Table B contains all the data from a specific database and Table A just contains one of the fields. For example,</p>
<pre>Table A
MFG_Name |Count
Dell | 15
Gateway|10</pre>
<p>Clicking on Dell would filter all the results from Table B where MFG_Name = Dell and show them below Table A as follows:</p>
<pre>Table B
Inventory_No | MFG_Name | Model_Name | Description
0001 | Dell |Inspiron |Desktop
0002 | Dell |Optiplex |Desktop</pre>
<p>how can I go about doing this? I've looked at using plugins that filter tables but my goal is not to have to print Table B until I have filtered it as it could contain 100000+ inventory numbers.</p>

Insert image after a link
|
<p>I have a large table that one column contains e-mail addresses (+/- 60), and I was told to add an e-mail icon after each address. I have been trying to use <code>anchors</code>,<code>.href</code> and <code>.indexof</code> to select the e-mail links, but have gotten no where (hence no code).</p>
<p>Can I get assistance on how to add <code><img src="/a/path/email.jpg" alt="e-mail" /></code> if the link's <code>href</code> contains a <code>mailto</code> using <strong>vanilla JavaScript</strong>, <em>no jQuery</em>.</p>

Honeycomb Hardware Acceleration
|
<p>I'm a little confused about the Honeycomb hardware acceleration. The documentation says to add a line to your manifest, but then it talks about hardware backing layers for views. If I simply add the manifest line, am I turning it on application-wide everywhere by default, or do I have to also turn it on for all the views in my app?</p>

Need help using John Resig’s Simple Javascript Inheritance
|
<p>John Resig’s Simple Javascript Inheritance: <a href="http://ejohn.org/blog/simple-javascript-inheritance/" rel="nofollow">http://ejohn.org/blog/simple-javascript-inheritance/</a></p>
<p>I tried to do such thing:</p>
<pre><code>var SomeClass = Class.extend({
init: function() {
var someFunction = function() {
alert(this.someVariable);
};
someFunction(); // should alert "someString"
},
someVariable: "SomeString"
});
var someClass = new SomeClass();
</code></pre>
<p>This should alert "someString", but it doesn't because inside the closure function <strong>someFunction</strong>, the value of <strong>this</strong> doesn't refers to the class, it is changed. <strong>That makes me unable to get access to the properties and functions of the class inside a closure function.</strong></p>
<p>Any suggestions?</p>

C# easy way to convert a split string into columns
|
<p>This is a rough one to explain. What I have is a string, </p>
<pre><code>string startString = "Operations\t325\t65\t0\t10\t400"
string[] splitStart = startString.Split('\t');
</code></pre>
<p>I need to turn this into</p>
<pre><code>Operations|325
Operations|65
Operations|0
Operations|10
Operations|400
</code></pre>
<p>The problem is i need this so be dynamic to if it has 10 splits I need it to do the same process 10 times, if it has 4, then it needs to do 4.</p>
<p>Any help would be awesome.</p>
<p>Sorry for any confusion, Operations is just this string, so it's not static. It really need to be [0] of the string split.</p>

jQuery selector question. Select all nodes that do NOT START with (string)
|
<p>Trying to assemble a rather complex jQuery selector here, and having trouble.</p>
<p>Essentially, I'm trying to grab all anchors that that 1) do not have a "rel" of "facebox", <strike>and</strike> <strong>OR</strong> 2) do not have an "href" that begins with "mailto".</p>
<p>This is what I've been trying to do:</p>
<pre><code>$('a[rel!=facebox], a[href!^="mailto"]')
</code></pre>
<p>Small variations of this don't seem to work. Is there some better way of going about this?</p>
<p>These selectors seem to work individually, but not when sitting consecutively in the same selector:</p>
<pre><code>$('a:not([rel=facebox]), a:not([href^=mailto])')
</code></pre>
<p><strong>Final solution:</strong> We have a winner!</p>
<pre><code>$('a:not([rel=facebox],[href^=mailto])')

When do I use struct instead of having class in c#?

<a href="http://stackoverflow.com/questions/85553/when-should-i-use-a-struct-instead-of-a-class">When should I use a struct instead of a class?</a> </p>
</blockquote>
<p>By Venkat K in the C# .NET forum. </p>
<p>29-Apr-09 07:38 AM</p>
<blockquote>
<p>The only difference between "class" and "struct" is that a struct defaults to having public members (both data members and function members) and a struct defaults to public inheritance, whereas a class defaults to private members and private inheritance. That is the only difference. This difference can be circumvented by explicitly specifying "public", private", or "protected" so a struct can be made to act like a class in ever way and vice versa.by convention, most programmer's use "struct" for data types that have no member functions and that do not use inheritance. They use "class" for data types with member functions and inheritance. However, this is not necessary or even universallly acepted. </p>

jQuery: Making a Favorite button with function?

<p>the class="addFavorite", is a normal grey star.</p>
<p>Then i have another class="AlreadyFavorite", that is a yellow star. </p>
<p>I want to make a function, so when you click on the grey star, it sends an ajax call(?) and then on success it turns yellow(changing class to AlreadyFavorite).</p>
<p>I know how to make a onclick function that send a ajax call, but how do i change the style/change the image icon to yellow?</p>
<p>CSS:</p>
<pre><code>.addFavorit{

height: 48px;

How to choose the right PHP Framework for web development?
|
<p>I'm a PHP Pro, but haven't use any PHP framework till now, so I have no clue on
how to choose a PHP framework. Do you have some tips to help me choose the/a right PHP Framework?</p>
<p>I want a stable and secure PHP framework for Projects with about 400 hours development time.
It should be possible to use the framework on Shared-Hosting-Webservers.
I don't need some AJAX support (I'm using extJS).
It would be nice if the framework supports Rapid Application Development
and object-relational mapping.</p>
<p>Also some of the standard-functions (Authentification, form validation) would
be nice. Caching would be a useful, but isn't needed.</p>
<p>Needs for a <a href="http://www.phpkode.com/projects/category/php-development-framework/" rel="nofollow">PHP framework</a>:</p>
<ul>
<li>Shared-Hosting-Webserver-Support</li>
<li>for Projects between 200 und 400 hours work</li>
<li>Developing Modell "Rapid Application Development" supported</li>
<li>object-relational mapping supported</li>
</ul>
<p>If possible:</p>
<ul>
<li>Caching</li>
<li>Already finished Modules (e.g. Authentification, form validation, ..)</li>
<li>Easy to learn</li>
</ul>
<p>Which PHP framework is the right one I am seeking for?</p>

Function scopes and global variables

console.log(foo, bar, window.foo); //1, 2, undefined
(function(foo){
console.log(foo, bar); //2, 2
})(bar);
</code></pre>
<p>I have two trivial questions regarding the code above:</p>
<ol>
<li><p>Why is <code>window.foo</code> undefined? Aren't all global variables attached to the window object by default?</p></li>
<li><p>Why is <code>foo ===</code>2 inside of the closure? I know that I'm passing the original <code>bar</code> with the alias <code>foo</code>, which is <code>2</code>, but outside of the function scope <code>foo</code> is still <code>1</code>. And as far as I know, the original <code>foo</code> can be accessed from inside of the closure as well. Is the "new foo" prioritized since it's passed as an argument to the IIFE?</p></li>

Writing in text view of different tabs in android
|
<p>I have to manage different text views in tabs for chatting in android.In my code if a list item is clicked new tab will be generated having one text view one EditText box and a button.With the construction of the tab a new class having will be initialized which will check whether there is any new message or not after every 30 seconds.If new message comes then this will write to that specific text view of the tab.My sample code is follwing:<code>ForPractice fp=new ForPractice(tabHost,"abcd");</code>When a tab is created this class is called.In its constructor I am sending tabtag and tabhost.And this class consists of following code: `public class ForPractice implements Runnable{
String str;
Thread thrd;
TabHost host;</p>
<pre><code>public ForPractice(TabHost tabHost,String name) {
str=name;
thrd=new Thread(this, name);

Open a file without loading it into memory at once
|
<p>Hi I have a problem to solve for college and I have a hard time understanding the sentence of the problem.</p>
<p>This is the problem I have :</p>
<blockquote>
<p>Reverse the order of bytes from a file without loading the entire file into memory at once.You have to solve this problem in C# , Java , PHP and Python.</p>
</blockquote>
<p>Now there are two things that I do not understand here.</p>
<p>First I am not sure if bytes refer to the actual characters of the file , or to something else.The problem does not state if it is a text file or not.</p>
<p>Second I am not sure how to open a file without actualy loading into memory.</p>
<p>This is how I would normaly approach this problem , but I think if I do it this way the file gets loaded into memory:</p>
<pre><code> string fileName = 'file.txt';
reader = new StreamReader(fileName);
string line;
while ((line = reader.ReadLine()) != null)
{
Console.WriteLine(line + "\n");
}
</code></pre>
<p>Also I am not sure how I would actualy reverse all the characters if I am reading it one line at the time.</p>
<p><strong>EDIT</strong> Sorry for posting in multiple languages I do not want the solution for the problem I only want to clarify it so I can solve it myself.I assumed that because I have to solve it in four different languages the concept would apply to all 4 and it did not matter who answer</p>

<p>Reason why is I have an app with 3 panels. The first panel by default is hidden and has a carousel. The carousel breaks if it is initiated when not visible. So I'd like to say as soon as the carousel or the div is visible, initiate the carousel.</p>
<p>Thanks</p>

createObjectURL does not work in ie10

<p>I am reading a base64 encoded file from indexedDB and trying to link to it as a blob url. The code below works fine in Chrome but when I click the link in ie10 nothing happens. I can see on the properties of the link that the href is blob:66A3E18D-BAD6-44A4-A35A-75B3469E392B which seems right. Anyone see what I'm doing wrong?</p>
<p>Download Attachment</p>
<pre><code> //convert the base64 encoded attachment string back into a binary array
var binary = atob(attachment.data);
var array = [];
for(var i = 0; i < binary.length; i++) {
array.push(binary.charCodeAt(i));
}
//create a blob from the binary array
var myBlob=new Blob([new Uint8Array(array)], {type: attachment.content_type});
//create a url hooked to the blob
downloadURL = (window.webkitURL ? webkitURL : URL).createObjectURL(myBlob);
//set the attachment link to the url

<p>I am new to Python.</p>
<p>Say I have a list:</p>
<pre><code>list = ['A','B','C','D']
</code></pre>
<p>The key for each item respectively here is 0,1,2,3 - right?</p>
<p>Now I am going to loop through it with a for loop...</p>
<pre><code>for item in list:
print item
</code></pre>
<p>That's great, I can print out my list.</p>
<p>How do I get the key here? For example being able to do:</p>
<pre><code>print key
print item
</code></pre>
<p>on each loop?</p>
<p>If this isn't possible with a list, where keys are not declared myself, is it possible with a Dictionary?</p>

Android plurals treatment of "zero"

<item quantity="zero">No item</item>
<item quantity="one">One item</item>
<item quantity="other">%d items</item>
</plurals>
</code></pre>
<p>I'm showing the result to the user using:</p>
<pre><code>textView.setText(getQuantityString(R.plurals.item_shop, quantity, quantity));
</code></pre>
<p>It's working well with 1 and above, but if quantity is 0 then I see "0 items".
Is "zero" value supported only in Arabic language as the documentation seems to indicate?
Or am I missing something?</p>

Javascript: parameter takes a random value when not passed in a callback function

<p>I am doing an ajax poll periodically. To achieve the same I have the following line of code:</p>
<pre><code>window.setInterval(pollForBids, 5000);
</code></pre>
<p>The function pollForBids is defined as follows:</p>
<pre><code>function pollForBids(supplierId){
alert(supplierId);
$.ajax({
method: "GET",
url : "/enterprize-sourcing/refreshBids.do",
async : true,
cache : false,
data : {action : "refreshList",
eventId : eventId,
lastRetrieveTime: makeFinite(latestBidTime, 0),
supplierId : makeFinite(supplierId, "")},
success: function(xml){
refreshBids(xml);
}
});
}
</code></pre>
<p>I have other places in the code where I need the parameter, but in this particular case I do not. But, the alert gives me a random integer value every 5 seconds. Shouldn't it always be undefined?</p>

jQuery: set opacity on div but don't apply to anchor tag inside div
|
<p>I need to be able to change the opacity of a div as people click on links (not inside the div). So I am setting the opacity to start with, and then changing it as need in my script.</p>
<p>Here is my initial setting:</p>
<pre><code>$('#config-title5a').css('background', '#ccc url(http://www.configureyourlaser.com/images/gradient.png) repeat-x 0 -10px').css({ opacity: 0.3 });
$('a#coolingtip').css({ opacity: 1.0});
</code></pre>
<p><code>a#coolingtip</code> is the anchor inside the div, which is called <code>#config-title5a</code>. Currently, this script changes the opacity on everything. How do I get it to apply the opacity change to the div, but not the anchor tag inside the div?</p>
<p>Here is the HTML:</p>
<pre><code><div id="config-title5">
Wavelength</div>
<div id="config-title5a">
<a id="wavelengthtip" title="Wavelength" href="<?php echo base_url(); ?>application/views/tooltips/wavelengthtip.php" rel="<?php echo base_url(); ?>application/views/tooltips/wavelengthtip.php">Learn More ›</a></div>

Is there a better solution to this loop?
|
<p>I'm making a website which basically displays a random image but I need a better bit of code of what I have at the moment. I'm hoping someone could come up with a better solution.</p>
<pre><code>$p = $_GET["p"];
$qrynumrows = mysql_query("SELECT * FROM pictures");
$numrows = mysql_num_rows($qrynumrows);
if (!isset($p)) {
$randid = rand(1, $numrows);
$qryrecord = mysql_query("SELECT * FROM pictures WHERE id='$randid'");
while ($row = mysql_fetch_array($qryrecord)) {
$rowp = $row["p"];
$rowremove = $row["remove"];
}
if ($rowremove == 1) {
header("Location: http://www.lulzorg.com/");
exit();
}
else {
header("Location: http://www.lulzorg.com/?p=$rowp");
exit();
}
}
</code></pre>
<p>So what it's doing is picking a random record from the database but it needs to check whether the record is allowed. The bit of code works fine but I'm sure there's a better/faster way to do it.</p>
<p>If $rowremove is equal to 0 then the image is allowed to display. If $rowremove is equal to 1 then the image is NOT allowed to display.</p>
<p>Thanks.</p>

javax.swing.Timer vs java.util.Timer
|
<p>I heard all <code>javax.swing</code> classes should only be used if Iam actually building a <code>Swing GUI</code>.
I would like to use <code>javax.swing.Timer</code> without <code>GUI</code> in order to create timer loop. Does it mean that without GUI shall i use <code>java.util.Timer</code>?</p>
<p>Is it big error to use <code>javax.swing.Timer</code> without <code>GUI</code> ? Can it cause some performance error or slowdown?</p>
<p>What are some approaches to creating a loop that will run passively or without halting the main thread?</p>
<p>Thanks in Advance!</p>

Attempt to get HTML from website using PHP cURL does not work
|
<p>I am attempting to write a script that can retrieve the HTML from my school's schedule search webpage. I am able to visit the web page normally when I visit it using a browser, but when I try to get it to work using cURL, it gets the HTML from the redirected page. When I changed the </p>
<pre><code>CURLOPT_FOLLOWLOCATION
</code></pre>
<p>variable from true to false, it only outputs a blank page with the headers sent. </p>
<p>For reference, my PHP code is</p>
<pre><code><?php
$curl_connection = curl_init('https://www.registrar.usf.edu/ssearch/');
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($curl_connection, CURLOPT_HEADER, true);
curl_setopt($curl_connection, CURLOPT_REFERER, "https://www.registrar.usf.edu/");
$result = curl_exec($curl_connection);
print $result;
?>
</code></pre>
<p>The website that I am trying to get the HTML of from cURL is <a href="https://www.registrar.usf.edu/ssearch/" rel="nofollow">https://www.registrar.usf.edu/ssearch/</a> or <a href="https://www.registrar.usf.edu/ssearch/search.php" rel="nofollow">https://www.registrar.usf.edu/ssearch/search.php</a></p>

CallLog.Calls Query By Date
|
<p>I am querying CallLog.Calls content provider for call details. Everything works fine except when I try to query by dates. That is, to get call details for a particular date or date range etc. I know the date are stored as long (millisecond format) so I tried to convert the date first and then query by it, but I must be doing something wrong here. Here's the query I am running, pls note that it works well when I remove the "WHERE DATE =" part or replace it by something like "WHERE TYPE=" etc. So, how do I run a query to get call details for a date or date range? Any help on this? Thanks. </p>
<pre><code>Cursor c = getContentResolver().query(CallLog.Calls.CONTENT_URI, null,
CallLog.Calls.DATE + "<=?",
new String[] { String.valueOf(dateSTR)}, ORDER_BY);
startManagingCursor(c);

Generating a user unique hash
|
<p>I need to generate an hash, that is unique for a user on an android device. Since they can have multiple users that seems difficult to me. I was about to use the IMEI of the device (or another device, if there is one), but since android supports multiple users, I have to use something else, without changing my permissions if possible (at the moment I have internet and read/write storage permissions)</p>
<p>Any Ideas?</p>
<p>For hashing itself I would use MD5 or SHA1.</p>

Login OnClick Event not firing
|
<p>This is my first attempt at creating an asp.net website so please be kind. I'm attempting to fire a click event on a submit button in ASP.NET, the template I'm using has this html</p>
<pre><code><div id="lightbox"></div>
<div id="loginbox-panel">
<a href="#" id="lightbox-close"></a>
<form action="#">
<fieldset>
<div class="frame">
<h4>TestSite</h4>

<input type="submit" value="Sign in" class="input-submit float-right" />
<a href="#" class="float-left">Forgot your password?</a>
</div>
</fieldset>
</form>
</div>
</code></pre>
<p>I believe the <code>input type="submit"</code> is client side but could be made to run a server side event using </p>
<pre><code><input type="submit" value="Sign in" class="input-submit float-right"
runat="server"
onserverclick="LoginButton_Click"/>
</code></pre>
<p>with code behind</p>
<pre><code>protected void LoginButton_Click(object sender, EventArgs e)
{
//login handler
}
</code></pre>
<p>However, the event is not firing! Please can someone advise how I can get the LoginButton_Click event to fire</p>

How to count word occurrences in an array of strings using c#?

<p>I'm new to programming, and I am trying to write a program that take in an array of strings (each index of the array being a word) and then count the occurrences of each word in the string. This is what I have so far:</p>
<pre><code> string[] words =
{
"which",
"wristwatches",
"are",
"swiss",
"wristwatches"
};
Array.Sort (words);
for (int i = 0; i < words.Length; i++)
{
int count = 1;
for(int j = 1; j < words.Length; j++)
{
if (words [i] == words [j])
{
count++;
}
}
Console.WriteLine ("{0} {1}", words[i], count);
}
</code></pre>
<p>Ideally, I would like the output to be something like:</p>
<p>are 1</p>
<p>swiss 1</p>
<p>which 1</p>
<p>wristwatches 2</p>

Passing Member Function Pointers Between Modules

<p>Just a curiosity question! <a href="http://www.codeproject.com/KB/cpp/FastDelegate.aspx" rel="nofollow">This</a> seems to suggest that member function pointers are in fact different sizes pending compiler and compile options used, and <a href="http://stackoverflow.com/questions/653697/is-it-safe-to-pass-function-pointers-as-arguments-to-dll-functions-and-invoke-the">this</a> seems to suggest that function pointers are passed just fine between modules, so what about member function pointers? I mean with all the hassles that are already presented in passing data between modules it would seem rather silly to even attempt this? Or what about scenarios involving static libraries? If two different compilers are used am I wrong to assume that any scenario involving the passing of a member function pointer would be fruitless?</p>
