jQuery: Handling background/container click
|
<p>I have a big div, and a small button inside the div.</p>
<p>When the div is clicked, I want it to do something.<br>
When the button is clicked, I want it to do something else.</p>
<pre><code>$('#myDiv').click(OnDivClicked);
$('#myButton').click(OnButtonClicked);
</code></pre>
<p>Currently when the button is clicked, both OnDivClicked and OnButtonClicked are fired.</p>
<p>How do you prevent OnDivClicked getting fired when the button is clicked?</p>
<p>Thanks in advance.</p>

Why is my app filtered for Android 1.5 and 1.6 devices?
|
<p>Our last update for our application caused it to be filtered out for Android 1.5 and Android 1.6 devices. We did not change anything in our manifest (aside from the updated version code). </p>
<p>These similar questions did not help:<br>
<a href="http://stackoverflow.com/questions/4952197/android-app-no-longer-visible-by-android-1-5-on-devices">Android App no longer visible by Android 1.5 on devices</a><br>
<a href="http://stackoverflow.com/questions/7225372/android-app-not-appearing-in-market-for-1-51-6-devices-bluetooth-is-androidreq">Android app not appearing in Market for 1.5&1.6 devices, Bluetooth is android:required="false"</a> </p>
<p>We created a test app with a stripped down manifest and compiled it with the Android 1.5 SDK. Even this basic app is filtered out. We tried contacting Android Market support five days ago but Google makes it pretty clear they don't want to provide support to developers and say that it's unlikely we'll get a reply.</p>
<p>Here is the <strong>full</strong> AndroidManifest.xml for the test app:</p>
<pre><code> <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.highwaynorth.test"
android:versionCode="6"
android:versionName="6.0">
<uses-sdk android:minSdkVersion="3" />
<application android:icon="@drawable/icon" android:label="@string/app_name">

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
</code></pre>
<p>Why is this being filtered?</p>

How to check for end of tag in Python using minidom?
|
<p>I'm trying to create an expression from an XML. Reading from top node I want to put the node one by one into a stack, once I hit a closing tag I want to pop all elements in the stack. How do I check the end of a tag ?.</p>
<p>TIA, </p>
<p>John</p>
<p>Answer: </p>
<p>OK, I think I've the solution, using a recursive function like this:</p>
<pre><code>def findTextNodes(nodeList):
for subnode in nodeList:
if subnode.nodeType == subnode.ELEMENT_NODE:
print("element node: ",subnode.tagName)
# call function again to get children
findTextNodes(subnode.childNodes)
print('subnode return: ', subnode.tagName)
elif subnode.nodeType == subnode.TEXT_NODE:
print("text node: ",subnode.data)
</code></pre>
<p>When the 'subnode return' it hits the closing tag!.</p>

In C# how to create a List<T> with a default count of zero?
|
<p>Rookie question: </p>
<p>I have been experiencing a minor bug in my mvc2 application. I was able to trace it back to this code:</p>
<pre><code>List<Stream2FieldTypes> Stream2FieldTypes = new List<Stream2FieldTypes>();
foreach (var item in stream.Stream2FieldTypes)
{
Stream2FieldTypes.Add(item);
}
</code></pre>
<p>The problem that I am experiencing is that when I instatiate the new list, it has a count of one. I'm thinking that this is probably due to my using the constructor. So I tried this:</p>
<pre><code>List<Stream2FieldTypes> Stream2FieldTypes;
foreach (var item in stream.Stream2FieldTypes)
{
Stream2FieldTypes.Add(item);
}
</code></pre>
<p>But, of course this will not compile because of an error on <code>Stream2FieldTypes.Add(item);</code>. Is there a way that I can create a <code>List<Stream2FieldTypes></code> and make sure that the count is zero?</p>

How to efficiently render different things at different times in a game?

<p>Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." </p>
<p>The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer.</p>
<p>I always wonder how more professional games do it. </p>

RDTSC vs. StopWatch
|
<p>I programmed my own string matching algorithm, and I want to measure its time accuratly,
to compare it with other algorithms to check if my implementation is better.</p>
<p>I tried (StopWatch), but it gives different time in each run, because of multiple processes running of the Windows OS. I heared about (RDTSC) that can get the number of
cycles consumed, but I do not know if it gives different cycles number in each excution too ?</p>
<p>Please help me; Can (RDTSC) give an accurate and same measurment of cycles for a C# function, or it is similar to (StopWatch) ? Which is the best way to get cycles number for a C# function alone without the other running processes ? and thanks alot for any help or hint</p>

C# check if one collection of values contains another
|
<p>Suppose I have two collections as follows:</p>
<p>Collection1:
"A1"
"A1"
"M1"
"M2"</p>
<p>Collection2:
"M2"
"M3"
"M1"
"A1"
"A1"
"A2"</p>
<p>all the values are string values. I want to know if all the elements in Collection1 are contained in Collection2, but I have no guarantee on the order and a set may have multiple entries with the same value. In this case, Collection2 does contain Collection1 because Collection2 has two A1's, M1 and M2. Theres the obvious way: sorting both collections and popping off values as i find matches, but I was wondering if there's a faster more efficient way to do this. Again with the initial collections I have no guarantee on the order or how many times a given value will appear</p>
<p>EDIT: Changed set to collection just to clear up that these aren't sets as they can contain duplicate values</p>

How to compare two values in Java?

<p>Any help?</p>
<p>EDIT: Some further info: I am doing some operations on two objects - on one the ops succeed, on the other they fail. However I can't tell what's different, that's why I need this comparison. I can't seem to get reflection to work, member not visible exception or smth like that on private members.</p>

js Diagonal movement at minute speeds
|
<p>There are numerous questions on SO similiar to this but not exactly as far as I could tell.</p>
<p>Want to move an object along a path at a slow pace. Here's an example of what I've got.</p>
<pre><code>var moverateX,moverateY;
function setup (){
var opp=targetY-startY;
var adj=targetX-startX;
var hyp=Math.sqrt ((opp*opp)+(adj*adj));
moverateY=10*(opp/hyp);
moverateX=10*(adj/hyp);}
function okgo (){
obj.style.left=currentX+moverateX+'px';
obj.style.top=currentY+moverateY+'px';
setTimeout (function (){okgo ();},50);}
</code></pre>
<p>It works but moves too quickly. If I change the number the ratio is multiplied by to a smaller one, the object misses the end target. eg:</p>
<pre><code>var moverateY=2*(opp/hyp);
var moverateX=2*(adj/hyp);
//moves slower but misses the end mark by a fair margin

How to add javascript to php page
|
<p>I see a lot of script adding Javascript to their webpages in different ways and am trying to figure out the correct way to do it. For example, in the header of one of the php scripts I use it has this:</p>
<pre><code><script type="text/javascript" src="/javascriptfile.js"></script>
<script type="text/javascript">
var stuff = "file.php";
var ip_add = '32.42.42.442';
</script>
</code></pre>
<p>What I don't understand is why would you ever put the full javascript code in the header instead of just including it within a file. For example, why not move the javascript mentioned about into it's own file and just just use this in your header:</p>

jQuery Sticking Fade On Clicks
|
<p>I have three divs with the class 'thumbs' and they are used to select products. I'm currently using the following code to highlight the current choice:</p>
<pre><code>$('.thumbs').hover(function(){
$(this).stop().fadeTo("normal", 1.0);
},function(){
$(this).stop().fadeTo("slow", 0.5);
});
</code></pre>
<p>By default all choices are at 50% opacity, when you hover over the choice it will fade to 100% opacity and when you move your mouse it will go back to 50%. The problem is I want it to stay at 100% when an option is clicked, and then only have the other 2 options changed on hover. Then when another option is clicks I want that to go to 100% opacity and the others to go back to 50%. I hope I've explained myself well, if not feel free to comment. Any help would be greatly appreciated.</p>

How to force the DropDownList to take both value and text of the source?
|
<p>I've struggling for hours now with this issue. I have a list that I keep in the Session</p>
<pre><code>Session["AllDev"] = taskData.DisplayAllDevelopers();
</code></pre>
<p>I use it later this way.</p>
<pre><code>_ddlAllDev.DataSource = (ListItemCollection)Session["AllDev"];
_ddlAllDev.DataBind();
</code></pre>
<p><strong>DisplayAllDevelopers()</strong> method returns a ListItemCollection. Each ListItem contains the <strong>ID</strong> of the Developer as Value and the <strong>name of the Developer</strong> as Text. But When I check the items collection, I find that the DropDownList has both the value and the text set to the name of the devoloper. Is there a way to force the DropDownList to keep the Value and the Text as the source is?</p>
<p>Thanks for helping.</p>

PHP beginner design patterns and frameworks
|
<p>I am planning to start learning PHP and MySQL for developing e-commerce type websites. I have 3 months of free time to start doing this, and a programming background of Java and javascript of 1 year of practical experience. </p>
<p>I have already selected 2 books that will get me started and get me on an intermediate level : <a href="http://rads.stackoverflow.com/amzn/click/0672329166" rel="nofollow">PHP and MySQL Web Development 4th Edition</a> and <a href="http://www.apress.com/9781590598641" rel="nofollow">Beginning PHP and MySQL E-Commerce
From Novice to Professional</a>.</p>
<p>I am interested in developing e-commerce websites and I want to do it right since I will also be doing it for other people in the near future (6-8 months from the moment I start). </p>
<p>While I am sure about the first book that will help me achieve what I need for the second I am open to suggestions.</p>
<p>My first problem is that these 2 books won't be enough for what I need. I have no experience in using MVC architecture which seems to be the main architecture these days for writing big and sustainable projects and also no knowledge of any other design pattern which is used these days. </p>
<p>Can anybody recommend a good book or resource for understanding and writing MVC projects and getting familiar with good OOP design patterns?</p>
<p>My second problem is that I am undecided if I should learn a PHP framework immediately or I should try working with it as it is. If I am going to learn a framework, I decided on Codelgniter. Is it a good choice for e-commerce development?</p>
<p>I mostly chose it because it is considered one of the fastest frameworks. I am not seeking to start a holy war on wether is best to use a framework or not what I want is to know if it is a good idea to learn a framework immediately after I learned PHP ? If it is or not a good idea I would like some arguments so I can better decide.</p>
<p>I already decided I will use a framework on some point so I can increase productivity so I am not seeking a debate.</p>

jQuery - Change text in an input field after it's created
|
<p>How can I write a script that will change an input field's text value, but the field is not yet created?</p>
<p>The script is loaded before the input field is created. It needs to know that when any input with a certain class is created, it will then have some text put in to its value. Can this be done with <code>live()</code>?</p>
<p>To clarify, the order of events are:</p>
<p><strong>1</strong> - Application-wide JavaScript for the page is loaded. This contains script something along the lines of:</p>
<pre><code>$('.myDiv input').each(function() {
$(this).val('some text');
});
</code></pre>
<p><strong>2</strong> - A second page-specific script is now loaded, which dynamically creates an input on the page, with no value. <strong>I CANNOT MODIFY THIS SCRIPT.</strong> This is important, I need a solution that does not modify this script (otherwise I wouldn't be posting here).</p>
<pre><code>$('.myDiv').html('<input type="text" />');

POST a HTML Form programmatically and display response

<p>I need to prepare ASP.NET site with form, fill form in code behind and then submit form to external site.</p>
<p>For example: user open www.myshop.com/pay.aspx, he does not have to fill anything because I fill form values in code behind and then user is automatically redirected to external site www.onlinepayments.com (with form data sent in POST).</p>
<p>I am able to make it work with regular hidden form and javascript that submits form but I dont like this way (user can see html).</p>
<p>So I use WebRequest class in code behind like in this answer: <a href="http://stackoverflow.com/questions/26857/how-do-you-programmatically-fill-in-a-form-and-post-a-web-page/26881#26881">How do you programmatically fill in a form and 'POST' a web page?</a></p>

python: convert "5,4,2,4,1,0" into [[5, 4], [2, 4], [1, 0]]

<p>Is there a "straightforward" way to convert a str containing
numbers into a list of [x,y] ints?</p>
<pre><code># from: '5,4,2,4,1,0,3,0,5,1,3,3,14,32,3,5'

</code></pre>
<p>By the way, the following works, but wouldn't call it straightforward...
Also, it can be assumed that the input str has been validated to make sure that it only contains an even number of numbers interleaved by commas.</p>
<pre><code>num_str = '5,4,2,4,1,0,3,0,5,1,3,3,14,32,3,5'
numpairs_lst = [] # ends up as [[5, 4], [2, 4], [1, 0], ...]
current_num_str = '' # the current num within the str; stop when a comma is found
xy_pair = [] # this is one of the [x,y] pairs -> [5, 4]
for ix,c in enumerate(num_str):
if c == ',':
xy_pair.append(int(current_num_str))
current_num_str = ''
if len(xy_pair) == 2:
numpairs_lst.append(xy_pair)
xy_pair = []
else:
current_num_str += c
# and, take care of last number...
xy_pair.append(int(current_num_str))

Is there any xml-include-like thing for Java class?

<p>When we make Android layout in XML, we can use <code>include</code> to make some other layout the part of the host layout. Is there such thing for Java class?</p>
<p>I am attaching a top bar layout to every screen and it contains buttons. Now in every Java class I have to copy/paste the initialization code. </p>
<p>Is there any shortcut for such scenarios? Can <code>Application</code> class facilitate anyhow? If anyone has a working solution, please share it with me. </p>
<p>For example, in XML I can use</p>
<pre><code>//...xml layout elements
<include layout="@layout/topbar" />
//...some other xml layouts
</code></pre>
<p>so it would be cool to be able to use in Java code something where I could instantly initiate buttons, register <code>onClick</code> events and set actions to these events. It all the same piece of code I am using, after all. </p>

Accesing Richtextbox from a class

{
public Form1()
{
InitializeComponent();
}
//Skipped the rest
public string ACText
{
set
{
ConsoleText.AppendText(value);
}
}

<p>Now from my class's constructor.</p>
<pre><code> public McDonalds(string email, string pass)
{
Form1 f = new Form1();
f.ACText = "test";
}
</code></pre>
<p>It's not showing any text in my richtextbox sadly. I know it works, because i can in the property use a messageBox and see that the value is passed into it.</p>

<p>In the first paragraph where you have to concatenate the string and then translate it using the <code>MiscDecoders->DecodeUCS2</code>, I am getting not printable chars as a solution, after concatenating and using the decoder.</p>
<p>In the second paragraph where you are told to run the script after adding the function-call at the bottom of the script, the Decoder tells me that he cannot handle the <code>arguments.callee.toString()</code> method and therefor wont run the script. </p>
<p>How outdated are those tutorials and how can I get them to work?</p>

Estimate seconds left (based on time & progress)
|
<p>I'm trying to estimate how many seconds is left of an MSI installation. Though I know this will not be accurate, my calculation seems more off than it should be - how can I improve? One problem is that often I find that the progress rockets from ~0% to ~95% which for a very long time evaluates to 0 seconds left.</p>
<p>I get the progress event from the MSIs, and each time progress is updated I do the following:</p>
<pre><code> private int CalculateSecondsLeft(DateTime start, int overallProgress)
{
lock (this)
{
if (overallProgress == 0)
{
return 0;
}
var timeSpent = DateTime.Now - start;
double cal1 = timeSpent.TotalSeconds / overallProgress;
double cal2 = cal1 * (100 - overallProgress);
return (int)cal2;
}
}

Why does my plist file exist even when I've uninstalled an app and wiped the simulator?
|
<p>I am trying to detect the existence of a plist file on application start. When my data class (descendant of NSObject) is initialized, it loads the plist file.</p>
<p>Before it loads, it checks to see if the file exists, and if it doesn't, it sets the data = nil instead of trying to process the array of data in the plist file.</p>
<p>However, every time it starts it indicates the file exists. Even when I uninstall the app in the organizer <strong>and</strong> when wiping the simulator directory (iPhone Simulator/3.0/Applications).</p>
<p>I have the following static method in a library class named FileIO:</p>
<pre><code>+(BOOL) fileExists:(NSString *)fileName {
NSString *path = [FileIO getPath:fileName]; // gets the path to the docs directory
if ([[NSFileManager defaultManager] fileExistsAtPath:path]) return YES;
else return NO;
}
</code></pre>
<p>In my data class:</p>
<pre><code>//if( [FileIO fileExists:kFavorites_Filename] ) [FileIO deleteFile:kFavorites_Filename];
if ([FileIO fileExists:kFavorites_Filename]) {NSLog(@"exists");
</code></pre>
<p>The "exists" is logged every time unless I un-comment the method to delete the file.</p>
<p>How can the file exist if I've deleted the app? I've deleted the simulator directory and uninstalled on the device but both say it still exists.</p>
<p>What gives???</p>

<p>So I posted the question yesterday (<a href="http://stackoverflow.com/questions/877328/jquery-disable-select-options-based-on-radio-selected-need-support-for-all-brows">Link</a>) and got the answer I needed but for the life of me I can't get this to happen if the value is selected on the body load. it only works if the user clicks the radio then it filters the options. HELP Please!!!</p>
<p>the Function</p>
<pre><code>jQuery.fn.filterOn = function(radio, values) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({value: $(this).val(), text: $(this).text()});
});
$(select).data('options', options);
$(radio).click(function() {
var options = $(select).empty().data('options');
var haystack = values[$(this).attr('id')];
$.each(options, function(i) {
var option = options[i];
if($.inArray(option.value, haystack) !== -1) {
$(select).append(
$('<option>').text(option.text).val(option.value)
);
}
});
});
});
};
</code></pre>
<p>How to call</p>
<pre><code>$(function() {

Comparing Two Strings

<pre><code> if ( [ somethingString isEqualToString: @"MyString" ] )
{ //do something } else { //do something else }
</code></pre>
<p>Now, I have examined <code>somethingString</code> with <code>NSLog</code> and it appears ok in that it shows what I expected. But, the if statement is not working.</p>
<p>I am thinking that even though the Debugger shows the object there before the if is executed, the type or something else is amiss.</p>
<p>The somethingString comes from the <code>UIPickerView</code> which is populated with an array of objects...if this makes any difference.</p>
<p>Any thoughts?</p>
<p>ps. I have tried using the compare: and that definitely does not work.</p>

How to edit library source files on NetBeans?
|
<p>I am doing JAVA project based on the SSJ (Stochastic Simulation in Java) libraries. In my project I have followed the required steps to import the SSJ library files and also the source files.</p>
<p>When looking at the SSJ library files in the project's Libraries branch, only class files appear shown, but when I open them I can view the source code (which I couldn't before, as I hadn't imported the sources) so I assume everything was imported correctly.</p>
<p>When I run the examples provided with the library everything runs fine and as expected. But if I try to change the source code for the libraries for instance, changing the text on an output, the changes I make to the source files aren't reflected in the output from the java programs.</p>
<p>Any hint on what I might be doing wrong?</p>
<p>I understand this might be hard to understand or test as I can't quite create and SSCCE for this matter. The library files are hosted here (http://www.iro.umontreal.ca/~simardr/ssj/ssj-20120216.zip) and the source code here (http://www.iro.umontreal.ca/~simardr/ssj/ssj-source.html).</p>

foreach (var user in users)

one.Properties["something"].Value = two.something;

</code></pre>
<p>'users' is a collection of string values. Where you see "something" (two places), I want to be using a string value from 'users'. How can I do this?</p>

dr["dept_name"] = dept_txt.Text;
AMSParent.con.dst.Tables["dept_tbl"].Rows.Add(dr);
AMSParent.con.dst.Tables["dept_tbl"].AcceptChanges();
AMSParent.con.dst.AcceptChanges();
AMSParent.con.dst.WriteXml(Application.StartupPath + "\\offlineTables.xml", XmlWriteMode.WriteSchema);
try { File.Delete(Application.StartupPath + "\\offlineTables.con"); }
catch { }
encdec.Encrypt(Application.StartupPath + "\\offlineTables.xml", Application.StartupPath + "\\offlineTables.con", "");
try { File.Delete(Application.StartupPath + "\\offlineTables.xml"); }

Including headers inside class declaration / definition
|
<p>I know you can do something like:</p>
<p>def.h:</p>
<pre><code>A();
int x;
</code></pre>
<p>A.h</p>
<pre><code>class A
{
public:
#include "def.h"
}
</code></pre>
<p>A.cpp</p>
<pre><code>A::A()
{
x = 0;
}
int main()
{
A a;
return 0;
}
</code></pre>
<p>My questions is: why would you do this? Are there any advantages? I can see how it would be helpful if you have some classes with the same members but not the same base, but is it worth the hassle? It's not very readable, is it?
Also, how does the compiler treat these includes? Does it just paste the content of the header where it's included (kind of like a macro)?</p>

compareTo method java
|
<p>I'm working on homework and need someone to walk me through something. I am learning about arrays and basically I have an array that collects a lastname, firstname, and score.
I need to write a compareTo method that will compare the last name and then the firstname so the list could be sorted alphabetically starting with the last names and then if two people have the same last name then it will sort the first name.</p>
<p>I'm confused because all of the information in my book is comparing numbers and not objects or I guess Strings? I think strings are considered objects when working with arrays.
This is really confusing me so if somone can walk me through it I would appreciate it.
Here is what I have coded so far but I know it's wrong but it at least explains what I think I'm doing.</p>
<pre><code> public int Compare(Object obj) // creating a method to compare
{
Student s = (Student) obj; //creating a student object
// I guess here I'm telling it to compare the last names?
int studentCompare = this.lastName.compareTo(s.getLastName());
if (studentCompare != 0)
return studentCompare;
else
{
if (this.getLastName() < s.getLastName())
return - 1;
if (this.getLastName() > s.getLastName())
return 1;
}
return 0;
}
</code></pre>
<p>I know the < and > symbols are wrong but like I said my book only shows you how to us the <code>compareTo</code> method using numbers which I think is kind of unfair to expect me to understand how to compare objects. </p>

Javascript popup window to be in fron and not steal focus
|
<p>As stated in the Title, i'm trying to figure out if it's possible in Javascript to:</p>
<ul>
<li>Open a popup through my parent site with window.open </li>
<li>Have that popup display in front of the parent</li>
<li>Not lose <strong>keyboard</strong> focus from the parent window.</li>
</ul>
<p>So something like the functionality of the popup notification of Windows Messenger for example</p>
<p>Any ideas?</p>
<p>Regards,
