Manually creating a javascript event object
|
<p>Say I have the following code:</p>
<pre><code>$('#someid').click(function(event) { myFunction(event); });
function myFunction(event)
{
// do something with event
}
</code></pre>
<p>And I would like to test <code>myFunction()</code> with an eval statement, without doing something like using <code>eval('$("#someid").click()')</code>;</p>
<p>Is there a way to manually create an event object in javascript that would work with an eval statement?</p>
<p>Also if myFunction is only used as an event handler, can it always assume <code>event</code> is not null?</p>

Calling this->get/this->set methods versus directly accesing member variables in C++
|
<p>Suppose I have a class <code>Foo</code>, with a private variable <code>bar_</code> containing some state for <code>Foo</code>. If necessary, I may write public get/set methods for <code>bar_</code>. Naturally, I avoid this as much as possible to maintain encapsulation.</p>
<p>Assuming I have these get/set methods, whenever I have to access or modify <code>bar_</code> within a method belonging to <code>Foo</code>, I usually do it directly to <code>bar_</code>, instead of using the get/set methods, which I use for accessing <code>bar_</code> from outside the class. I have no justification other than concerns regarding the speed of directly accessing the variable versus calling the methods, but I suspect that if the get/set methods are defined inline (which they are) it shouldn't make a difference. Does it make a difference? Does <code>const</code>ness play a role in this?</p>
<p>So far I haven't had any problems with this, but I have a lingering feeling I am Doing It Wrong. Are there any compelling arguments for not doing it? Any guidelines regarding this?</p>

Why Python for web development?
|
<p>I'm wondering if learning this language or not.</p>
<p>I've been 15 years mainly coding with PHP. I know C, C++, Java, Perl … but PHP has solved all of my problems for web development.</p>
<p>I've read carefully this: <a href="http://wiki.python.org/moin/PythonVsPhp" rel="nofollow">http://wiki.python.org/moin/PythonVsPhp</a></p>
<p>I find Python useful for sysadmin tasks for example, or for first programming language learning. Sincerely, I love its cleanliness and clarity (it's like a "Jquerized PHP") … but I'm still finding blogs defending Python for web development … Why ? </p>
<p>Can anyone explain me advantages of Python for web ?</p>

How to access a downloaded internal-file icon and use as a drawable e.g. in setIcon(drawable)
|
<p>I download a png icon and store it on the internal file system.
How can I use this icon in a similar manner to a drawable in res/drawable.
I can read it and pulls its ears, but how to use it in a setIcon() method?
Does an internal file have a resource id? (wishful thinking).</p>
<p>I notice someone suggest saving to res/raw, but you cant write to application folders anyway.</p>
<p>I've been using: *openFileOutput(filename, Context.MODE_PRIVATE);*
But maybe I need to create a File object and do the usual Java stuff. Even so,
how to grab it as a drawable in my code?</p>
<p>Thanks.</p>

PHP echo directory contents (as links) not working
|
<p>I have a php file called download.php which I link to pdf files in a directory. This allows them to appear as links but open 'save as' instead of trying to open in a web page. Trouble is that I can't get the following code to work. It repeats the directory items, with the download.php appended, but I think my php semantics might be slightly wrong! Anyone got any ideas? Perhaps not enough info here to work out, but worth a try: This is the code that sits on the page presenting the various pdf files (ordered by dateLastModified):</p>
<pre><code><?php
// *** Folder List Repeater Start
while ($MeetingMinutes->canRepeat()) {
?>
<?php echo '<p><a href=\"http://www.duncton.org/download.php?file=login/uploads2/'.$MeetingMinutes->folderList('name').'</a></p><br />'; ?>
<?php
$MeetingMinutes->MoveNext();
}
$MeetingMinutes->endRepeater();
// *** Folder List Repeater End
?>

Contigency table
|
<p>I am struggling to find the Java code for this problem. Firstly, I am in a beginner level and this question were hard for me to answer. I know that this used a 2D array right? But I having problem to write the Java code for this question. </p>
<p>Here is the question:</p>
<blockquote>
<p>Write a Java program that</p>
<ol>
<li>queries a user for the number of rows and columns of a contingency table,</li>
<li>read the data, row by row and</li>
<li>displays the data in tabular form along with the row totals, column totals and grand
total.</li>
</ol>
<p>For example if the six data of 2x3 table are</p>
<p>1,3,6,7,9, and 8. the program displays these six numbers together
with the appropriate totals as</p>
<pre><code>1 3 6 | 10
7 9 8 | 24
8 12 14 | 34
</code></pre>
<p>The character '|' is used to separate the data from the row totals</p>

Array of subclasses and onClick()
|
<p>I want to create by code an array of objects that are subclasses of Button.</p>
<pre><code>public class MyButton extends Button {
private Context ctx;
private int status;
public MyButton(Context context) {
super(context);
ctx = context;
status = 0;
}
private click() {
status = 1;
// OTHER CODE THAT NEEDS TO STAY HERE
}
}
</code></pre>
<p>In the main activity I do this:</p>
<pre><code>public class myActivity extends Activity {
private MyButton[] myButtons = new MyButton[100];
@Override
public onCreate(Bundle si) {
super.onCreate(si);
createButtons();
}
private void createButtons() {
for (int w=0; w<100; w++) {
myButtons[w] = new MyButton(myActivity.this);
myButtons[w].setOnClickListener(new View.onClickListener() {
public void onClick(View v) {
// ... (A)
}
});
}
}
}
</code></pre>
<p>Now I want the click() method inside MyButton to be run each time the button is clicked.
Seems obvious but it is not at my eyes.</p>
<p>If I make the click() method public and run it directly from (A), I get an error because myButtons[w].click() is not static and cannot be run from there.</p>
<p>In the meantime, I an not able to understand where to put the code in the MyButton class to intercept a click and run click() from there. Should I override onClick? Or should I override onClickListener? Or what else should I do?</p>
<p>How can I run click() whenever one of myButtons[] object is clicked?</p>
<p>Thanks for the help.</p>

<p>I know that's wrong, I just have no idea how to compare two fields from two separate functions. The error message will pop up regardless of what I do. Even if I violate the rules for field 1 and 2 the error message will pop up with those when it shouldn't.</p>
<p>If there is somewhere I can read up on how to do this would be excellent for future reference.</p>
<p>any help would be greatly appreciated, thanks.</p>

Javascript - return false error
|
<p>I have a form validation function that loops through the form elements checking for empty fields - code below:</p>
<pre><code>function formValidate(ourform){
var formelems = document.getElementById(ourform).elements;
for (var i=0; i<formelems.length; i++){
if(formelems[i].value == "") {
alert("Empty Field(s). Please fill in all the fields.");
return false;
}
}
}
</code></pre>
<p>the problem is that my form does not return false if there's an empty field - it processes the form. I have solved this before but now i just cannot remember how.</p>
<p>Thanks.</p>

replacing jquery.live() with jquery.on() doesn't work
|
<p>I have several textboxes that are added dynamically after an ajax call. These boxes are tied to event handlers with .live() that currently work fine. I want to replace that with the newer .on() function.</p>
<p>This is what I have</p>
<pre><code>$('.MyTextBox').live({
mouseenter: function () { .... },
mouseleave: function () { .... },
blur: function () { ... }
});
</code></pre>
<p>When I replace .live() with .on() it doesn't work; the textboxes don't display their normal behavior after they're added.</p>
<p>If I write <code>$('#MainDiv .MyTextBox').live({...</code> , where MainDiv is the top DOM element where all the action happens, nothing happens either.</p>
<p>What am I missing?</p>
<p>Thanks</p>

How to use subscriberCellularProviderDidUpdateNotifier
|
<p>I have done something like</p>
<pre><code>CTTelephonyNetworkInfo *networkInfo = [[CTTelephonyNetworkInfo alloc] init];
networkInfo.subscriberCellularProviderDidUpdateNotifier = ^ (CTCarrier * carrier)
{Do some stuff here
};
</code></pre>
<p>to get the notification when the cell service provider changes and do some tasks.The documentation says:</p>
<blockquote>
<p>A block object that is dispatched on
the default priority global dispatch
queue when the user’s cellular
provider information changes. This
occurs, for example, if a user swaps
the device’s SIM card with one from
another provider, while your
application is running.</p>
<p>To handle changes in cellular service
provider information, define a block
in your application and assign it to
this property. The block must be
implemented to support being called
from any context.</p>
</blockquote>
<p>I am not sure where to implement this in my code and will it exceute if my application is running in background or suspended. </p>

JavaScript Query

<p>I have a field named "GROSS AMOUNT" </p>
<p>If the gross amount is zero, then the javascript message confirmation asks the user whether the user should continue saving with zero amount and if the user presses cancel, even the server side save button should not be active, it should return back to the panel of the gross amount.</p>
<p>I have used the following code for the client side.</p>
<pre><code>function show_confirm() {
// var txttemp = document.getElementById("<%=txtSAmt.ClientID %>").value;
var menu = $find("<%= this.txtSAmt.ClientID %>");
var check;
if (menu != null) {
check = menu.get_value();
}
if (check == '0') {
var r = window.confirm("Gross Settlement Amount is 0.Press Cancel to Change, Press OK to save anyway");
if (r == 'false') {

Readlines() vs. Read() - Can I convert data back and forth between the two functions?

<p>I have a module file containing the following functions:</p>
<pre><code>def replace(filename):

return match
def count_words(newstring):
from collections import defaultdict
word_dict=defaultdict(int)
for line in newstring:
words=line.lower().split()
for word in words:
word_dict[word]+=1
for word in word_dict:
if'risk'==word:
return word, word_dict[word]
</code></pre>
<p>when I do this in IDLE:</p>
<pre><code>>>> mylist = open('C:\\Users\\ahn_133\\Desktop\\Python Project\\test10.txt').read()
>>> newstrings=replace(mylist)
>>> newone=count_words(newstrings)
</code></pre>
<p>test10.txt just contains words for testing like:</p>
#
<p>risk risky riskier risk. risk?</p>
#
<p>I get the following error:</p>
<pre><code>Traceback (most recent call last):

dynamic String.Format depending of params

<p>Giving the following examples: </p>

<p>another use case:</p>
<pre><code>String.Format("({0}) {1}-{2}", countryCode, areaCode, phonenumber);
</code></pre>
<p>if I only have phonenumber, I would end up with something like "() -5555555" which is not desirable. </p>

</code></pre>
<p>in this case, I would like to include the s in the [] if the value > 1 for example.</p>

Best place to save Java configuration information
|
<p>I am writing a library which uses some configurations. These configuration will not change frequently but will possible change in the future. Therefore I don't want to hard code them in the code.</p>
<p>What is the best way of doing this for a Java library? One possible solution is to inject it and hard code them in a DI configuration file I assume. But this requires code change as well.</p>
<p>What is the most typical way of doing this?</p>
<p>Many thanks</p>

redirecting a page link and changing page text based on link
|
<p>OK I am not sure if the question title is actually correct , newbie web developer here so bear with me.<br />
This is an ASP.NET webiste running on IIS 6.0<br />
So here is the problem: I have two pages called Page1 and Home<br />
you can navigate to both like so<br />
www.mysite.com/Page1.aspx, www.mysite.com/Home.aspx</p>
<p>Page1 is now undergoing a lot changes so that it is going to end up looking a lot like Home except for some really small text changes. Also there are a number of emails in the wild with customers that link to Page1 and \ or Home </p>
<p>What I want is a solution that does the following </p>
<ol>
<li><p>Create One page( say newhome.aspx) which displays the correct text based on the URL of the link that people clicked on to get here </p></li>
<li><p>Let existing links go to this new page( and of course as per the above requirement the appropriate text would be displayed) </p></li>
</ol>
<p>I guess they sort of are the same requirement , bottom line I want only one page and all legacy links to continue to work as in get redirected to this new page</p>
<p>Thanks </p>

C++ simple program realization
|
<p>I need your help to get started with a good implementation thinking.</p>
<p>I need to create a simple program with the following:
1. A function with two parameters, first parameter is a name (char*), and the second parameter is the number of times you would like to print this name to the screen(int).
If the second parameter wasn't supplied in the function call, it should print the name 10 times.
If the first parameter wasn't supplied in the function call, it should print the author name / the writer of the program (i.e my name).</p>
<p>I was thinking to create the following function with default parameteres:</p>
<pre><code>void printTextToScreenNTimes(char * text = "guy", int n = 10);
</code></pre>
<p>This function implementation is the following :</p>
<pre><code>void printTextToScreenNTimes(char * text, int n) {
int i;
for (i = 0; i < n; i++)
cout << text << " ";
}
</code></pre>
<p>My problem arises as I try to print my default name 2 times. For example if I want only using the following function call: </p>
<pre><code>void printTextToScreenNTimes(3);
</code></pre>
<p>I would like the function to print the default name (in this case "guy") 3 times but It's impossible because I must fill the first parameter.</p>
<p>Do I have no choice but using a global parameter holding my name?</p>

Managing big amount of data (around 400Mb)
|
<p>I am thinking about developing a birds catalog for Android.
It will contain many pictures and audio files, around 400Mb.</p>
<p>I am starting in this world but after some reading I didn't find too much info about such kind of applications. I have following questions:</p>
<p>1.- What kind of options do I have for installation? 400Mb downloaded from Android Market? Minimal installation from Android Market and in the first execution connect to a second server to download all the data? Other options?</p>
<p>2.- Which is the best way to store such amount of data? File system in the SD Card? SQLite DB?</p>
<p>3.- Is there any way to specify in the manifest file, the minimum file system space required to avoid failure installations (imagine you pay for the app, and the app doesn't install because there is no enough space)?</p>
<p>Any tip or pointer to documentation about this kind of applications will be appreciate.</p>
<p>Thanks in advance,</p>

Why am I getting this warning about my app delegate and CLLocationManageDelegate?
|
<p>Observe this perfectly simple UIViewController subclass method:</p>
<pre><code>-(IBAction)launchSearch
{
OffersSearchController *search = [[OffersSearchController alloc]
initWithNibName:@"OffersSearchView" bundle:nil];
EverWondrAppDelegate *del = [UIApplication sharedApplication].delegate;
[del.navigationController pushViewController:search animated:YES];
[search release];
}
</code></pre>
<p>On the line where I get *del, I am getting a compiler warning that reads, <code>Type 'id <UIApplicationDelegate>' does not conform to the 'CLLocationManagerDelegate' protocol</code>. In fact, my app delegate DOES conform to that protocol, AND what I'm doing here has nothing at all to do with that. So what's up with that message?</p>
<p>Secondary question: sometimes I can get to my navigationController via <code>self.navigationController</code>, and sometimes I can't, and have to go to my app delegate's property to get it like I'm doing here. Any hint about why that is would be very useful.</p>

<p>This should be common Java and native may be Android. It is an absurdity can not pass an object of one activity to another "type object". There are extreme cases you do not want implement parcelable because it does not work!</p>

pdf combo box javascript
|
<p>Can someone help me out? I need two combo boxes form my pdf. </p>
<p>As an example, I need the first to list the following: Dodge, Chrysler, Jeep. The second combo box to read models of that make. </p>
<p>For Dodge lets use the example Caliber, Charger, Challenger. for Jeep; Patriot, Compass, Wrangler. And for Chrysler how about: 200, 300 and Sebring. </p>
<p>So when Dodge is selected, the second combo box will show models of that partifular make. Simple right? I of course will name my first combo box "Make" and the second "Model". I need a script to make this happen and am NOT versed in javascript at all. I just know that is what needs to happen. </p>
<p>Something I can copy/paste? Anyone? I can add more makes/modules to the script once I get the basic layout. :)</p>

If internet requires authentication for actually connecting to be able to download?

<p>My application requires using internet connection to download some file from a link. I have a internet connection which uses proxy and needs authentication. Somehow when I try to connect to internet it never asks for this authentication hence is unable to download file.</p>
<p>What I want to ask is that is there any way to detect if the internet connection of the user requires authentication to download files from internet, so that in-case if it is required my application can ask the user to open a normal internet browser of device and provide the wanted authentication.</p>

audioTrack play() plays only once

<p>using Android's AudioTrack for the first time.
I have created a class AndroidAudioDevice. I init it with this constructor:</p>
<pre><code> public AndroidAudioDevice( ){ // constructor
Log.i("Audio", "constructor");
int minSize =AudioTrack.getMinBufferSize( SAMPLE_RATE, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT );
track = new AudioTrack( AudioManager.STREAM_MUSIC, SAMPLE_RATE,
AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT,
minSize, AudioTrack.MODE_STATIC);
createSample();
track.write( buffer, 0, buffer.length );
};
</code></pre>
<p>(SAMPLE_RATE is set to 44100).</p>
<p>My main activity simply has a button, which calls </p>
<pre><code>public void playSound(){
track.play();
Log.i("Audio", "playState: " + track.getPlayState());
};
this works find BUT ONLY ONCE! If I press the button again no sound anymore.
</code></pre>
<p>BTW: Log.i displays a "3" for the playstate</p>
