divs hide correctly on page load, but need to show when back button is clicked
|
<p>I have several divs that are to be hidden on page load on a html form I am designing. Some contain text fields, some contain dropdown boxes. The are shown based on when certain radio buttons are clicked in the form. I am using javascript to hide the divs. Here is the code I am using:</p>
<pre><code><script language="JavaScript">
function start() {
hide('hideablearea');
hide('nontenant');
hide('conftype');
hide('rec_roomlayout');
hide('req_roomlabel');
hide('req_roomdrpdwn');
}
window.onload = start;
</script>
</code></pre>
<p>It works perfectly. My problem is...when the form is submitted and there is an error (for example, the user forgets to complete a required field) and clicks the back button, this function fires again and hides everything..and I want the hidden divs which have info inthem to show at this point. Any idea on how to achieve this?</p>
<p>Thanks in advance!</p>

Varying iPhone deployment target: Handling Framework constants
|
<p>I am building an app that needs to work on multiple versions of iPhone OS and makes use of increased accuracy for Core Location in iOS4. </p>
<p>I have code that does the following:
<code>
if ([m_locationManager respondsToSelector:@selector(startMonitoringSignificantLocationChanges)]) {
m_locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
}
else {
m_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
}
</code></p>
<p>in this case, kCLLocationAccuracyBestForNavigation is a constant introduced in iOS 4, and startMonitoringSignificantLocationChanges is a method of m_locationManager only introduced in iOS4. </p>
<p>My problem is, that this code is failing on an iPhone 3.1.3 device. It is trying to link to kCLLocationAccuracyBestForNavigation, but it can't find the symbol. My question is, how do I only link to this symbol in the iOS4 version, but not the iPhone 3.1.3 version?</p>
<p>Thanks,
C</p>

Javascript function which does not return a value in every case

Developing Python Module
|
<p>I'd like to start developing an existing Python module. It has a source folder and the setup.py script to build and install it. The build script just copies the source files since they're all python scripts.</p>
<p>Currently, I have put the source folder under version control and whenever I make a change I re-build and re-install. This seems a little slow, and it doesn't settle well with me to "commit" my changes to my python install each time I make a modification. How can I cause my import statement to redirect to my development directory?</p>

Using jquery's on in place of live - how can I get the filtered elements
|
<p>Using jQurey, I am replacing my old .live() event bindings with .on(), like this:</p>
<pre><code>$(document).on(event, selector, function () {
console.log($(this)); //$(this) refers to the $(document) element, not the selector
});
</code></pre>
<p>What I want to do is get access to the element that this event is being applied to. Any ideas?</p>
<p>This works:</p>
<pre><code>$(selector).on(event, function () {
console.log($(this)); //$(this) refers to the selector
});
</code></pre>
<p>But it doesn't work the same way as live - new elements added to the document that match the selector won't be bound...</p>
<p>Thanks!</p>

PHP: Getting contents of a file that is newer than a time
|
<p>Currently I have a PHP scripts that serves a medium amount (200 lines) of text. What I was wondering if it were possible to get the contents of a text file that is newest than a time, perhaps PHP's filemtime() for its last modification.</p>
<p>Is it possible to get the contents of a text file in this manner?</p>
<p>Edit: filemtime() is illogical since it wouldn't have any updates past that time.</p>
<p>To clear it up, I'm trying to get all the inner contents of a text file that is newer than a time.</p>
<p>Example: line1 was posted at time1, line2 was posted at time2, so on. I would want to be able to specify time2 and get the contents of the file that is newer than time2.</p>

simulate ipad click sound with mp3/ogg (web development)

<p>I am simulating a "click" sound on every anchor tag and submit button click on the mobile website that I'm working on using the following code:</p>
<pre><code> <audio id="mySoundClip" style=" display:none; visibility:hidden;">
<source src="@Url.Content("~/Content/audio/Click.ogg")" type="audio/ogg">
<source src="@Url.Content("~/Content/audio/Tock.mp3")" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
<script type="text/javascript">
var homeURL = '@Url.Action("Index", "Home")';
var audio = $("#mySoundClip")[0];
$("[href]").click(function () {
//alert("a clicked");
audio.play();
});
$(":submit").click(function () {
//alert("submit button clicked");
audio.play();
});
</script>
</code></pre>
<p>It's working as expected but there is a slight delay in when the sound file actually plays while clicking the anchor tags/submit buttons. Is there a way to play the sound file a little sooner than when it actually plays so it will seem like a native click?</p>

<p>I have the following code:</p>
<pre><code>public Form1()
{
InitializeComponent();
string strRadio = Utils.ReadFile(strTemp + @"\rstations.txt");
string[] aRadio = strRadio.Split(new string[] { "#" }, StringSplitOptions.RemoveEmptyEntries);
for (int i = 0; i < aRadio.Length; i += 2)
{
listBox.Items.Add(aRadio[i]);
}
}
private void listBox_SelectedIndexChanged(object sender, EventArgs e)
{
int index = listBox.SelectedIndex;
MessageBox.Show(aRadio[(index+1)]);
}
</code></pre>
<p>Now the error is <code>The name 'aRadio' does not exist in the current context</code>. Which comes from <code>MessageBox.Show(aRadio[(index+1)]);</code>. Do I need to declare the <code>aRadio</code> as public or something? If so, how would this be done?</p>

How to check if the number of lines in the file equal the number of characters in each of the lines?
|
<p>Reads the specified file and treats its contents as a list of strings (one per line).
Checks for the following conditions in the input file:</p>
<p>The file must exist and be available for reading. In other words, the call to open should not raise an exception.</p>
<p>The file must contain between 3 and 10 lines of text. That is, 3 is the minimum acceptable number of lines, and 10 is the maximum number of lines.</p>
<p>All lines must contain exactly the same number of characters.</p>
<p>Each line must contain between 3 and 10 characters. That is, 3 is the minimum acceptable number of characters, and 10 is the maximum. The number of characters per line does NOT have to equal the number of lines in the file.</p>
<p>The only acceptable characters are <code>'x'</code>, <code>'X'</code>, <code>'y'</code>, <code>'Y'</code>, and <code>'_'</code>.</p>
<pre><code>correct_string = False
while correct_string is False:
string = input("Enter a string? ")
if len(string) != len(string):
print("Error: string must have the same number of characters.")
else:
incorrect_char = False
for i in string:
if i != "X" and i != "x" and i != 'Y' and i != 'y' and i != "_":
incorrect_char = True
if incorrect_char is False:
correct_string = True
else:
print("Invalid Character. Contains characters other than 'X', 'x', 'Y' 'y',and '_'")

DropDownList SelectedIndexChanged event fails over the internet
|
<p>I have two ASP.net DorpDownLists in a web page. When the selection changes on the first drop down list, the client is expected to do a postback and the the server will populate the second drop down list based on the selection.</p>
<p>I have this page working as expected on the intranet but when it is accessed from the internet, the postback happens(I have verified the __EVENTTARGET with Burp Proxy and it is working) but the server is not calling the SelectedIndexChanged event. </p>
<p>Anybody ever faced something similar? Any suggestions or recommendations on how to resolve?</p>

Execute scripts later in time
|
<p>For a personal game I'm working on, I'd like to have a php function work over a certain period of time.</p>
<p>For example, right now it's set so that if the user wishes to purchase soldiers in the game, he fills out the form and when it's submitted, the user's database entry is instantly updated to reflect the change in soldiers.</p>
<p>What I would like is to have a time delay between the form submission and when the soldiers actually appear (to simulate training time, etc.). </p>
<p>I thought of one possible approach, but I hope it isn't the best one. I could create a new database table, "actions" that contains the type of action (i.e. the task to execute, in this case training soldiers), a parameter (the number of soldiers), and the action's start/end times. Whenever the user loads the page, the page checks to see if any actions have been completed and executes them if they are.</p>
<p>The key problem with this is that actions only execute when the user loads the page. He could buy soldiers and have them not appear until whenever he happens to log in, potentially leaving him vulnerable for large amounts of time.</p>
<p>I could resolve this by checking all user's actions whenever anyone loads the page, but I believe this would be unnecessarily taxing on the server, in addition to being fairly difficult to implement.</p>
<p>Does anyone have better ideas, or is my train of thought the best approach there is? Thank you!</p>

Strange PHP output buffering

In case of second server there is no output for 10 seconds and entire output is displayed at once. What might be wrong int second case?

Implementing a wrapping check box list or a tag list in Android
|
<p>A standard list of check boxes takes up a lot of vertical real estate:</p>
<pre><code>[ ] Option 1
[X] Opt 2
[X] Loooooong option 3
[ ] Option 4
</code></pre>
<p>What I would like to do is either wrap them:</p>
<pre><code>[ ] Option 1 [X] Op 2 [X] Loooooong option
3 [ ] Option 4
</code></pre>
<p>Or something like the stackoverflow Tags field:</p>
<pre><code>[X] Loooooong option 3 [X] Opt 2
Tags: [ Optio ]
Option 1
Option 4
</code></pre>
<p>I've not been able to find a suitable class to do that, and I'd rather not reinvent the wheel. As each field will have different lengths (for example, contact names) using a TableLayout or GridView doesn't make sense.</p>

What is the fastest way to check if a class has a function defined?
|
<p>I'm writing an AI state space search algorithm, and I have a generic class which can be used to quickly implement a search algorithm. A subclass would define the necessary operations, and the algorithm does the rest. </p>
<p>Here is where I get stuck: I want to avoid regenerating the parent state over and over again, so I have the following function, which returns the operations that can be legally applied to any state: </p>
<pre><code>def get_operations(self, include_parent=True):
ops = self._get_operations()
if not include_parent and self.path.parent_op:
try:
parent_inverse = self.invert_op(self.path.parent_op)
ops.remove(parent_inverse)
except NotImplementedError:
pass
return ops
</code></pre>
<p>And the invert_op function throws by default. </p>
<p>Is there a faster way to check to see if the function is not defined than catching an exception? </p>
<p>I was thinking something on the lines of checking for present in dir, but that doesn't seem right. hasattr is implemented by calling getattr and checking if it raises, which is not what I want. </p>

Best Practice - Allow offline use of android app?
|
<p>currently I'am developing an Android native app which have to communicate with a server (for ex. via REST) to load, save data etc.</p>
<p>Now I'm considering the offline scenario. I also want the user to save data if the mobile phone has currently not network connection. If the network connection is up again I want to sync the user data with my server. </p>
<p>Do anyone know some best practice to achieve this. I'm considering using a couchdb for replication, but I'm wondering if there are other nice ways to support offline use of my app.</p>

unable to display images from database via php array
|
<p>Learning php!</p>
<p>I have a sql database which contains a table called 'images' which stores image paths that users would upload. The problem I am having is pulling the image paths from the database to a PHP array, then using the paths to display the images on the screen as a , list item. However when I run the page nothing is displayed.</p>
<p>code for database connection:</p>
<pre><code>include('Database.php');
class Images extends Database{
private $_images = array();
public function __construct(){
$conn = $this->create_connection('read');
$sql = "SELECT image_path FROM 'items' WHERE catagory='tshirt'";
$result = $conn->query($sql)or die(mysql_error());
while($paths = mysql_fetch_array($result)) {
$this->_images[] = $paths['catagory'];
}
}
public function getItems() {
return $this->_images;
}
</code></pre>
<p>code for the view:</p>
<pre><code><ul>
<?php
require ('../model/Images.php');
$imageArray = array();
$images = new Images();
$imageArray[] = $images->getItems();
foreach($ImageArray as $value){
echo '<li><img src="'.$value.'"></li>';
}
?>
</ul>
</code></pre>
<p>I executed the SQL query using phpmyadmin, which query's correctly. Also I have simulated the database data by adding the image paths manually to test looping through array.</p>
<pre><code>private $_images = array('./images/tshirt1.jpg', etc, etc);
</code></pre>
<p>so I know the foreach loop and query work. The 'create_connection' function I have used before, connecting to the same database without any issues, I am a bit
stumped, but I think it may be connected to the mysql_fetch_array section?</p>
<p>Am I using the correct approach? or is there a better way to solve this issue?</p>
<p>Hope someone can point me in the right direction!</p>
<p>Thanks</p>

How to disable an item in a Spinner
|
<p>Is it possible to display particular entries in a Spinner list as disabled?
i.e. I want to always display a spinner with 4 entries (North, South, East and West, say), but I want to be able to disable any one of these so that is appears greyed out and not selectable.</p>
<p>Is this possible, or will I have to recreate the list each time, leaving out the invalid entries?</p>

Adding <tr> from repeater's ItemDataBound Event
|
<p>My repeater's templates generate a table, where each item is a table row.<br>
When a very very specific condition is met (itemdata), I want to add an additional row to the table from this event.</p>
<p>How can I do that? </p>
<pre><code>protected void rptData_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item ||
e.Item.ItemType == ListItemType.AlternatingItem)
{
bool tmp = bool.Parse(DataBinder.Eval(e.Item.DataItem, "somedata").ToString());
if (!tmp && e.Item.ItemIndex != 0)
{
//Add row after this item
}
}
}
</code></pre>
<p>I can use e.Item.Controls.Add() and add TableRow but for that I need to locate a table right?<br>
How can I solve that?</p>

How do I define fire_event, undefined fire_event error

<p>I'm cleaning up all the errors in an old script and I'm getting one that says <code>undefined function fire_event</code>. How do I define fire_event. everything works fine but i've turned on error_reporting(E_ALL); to fix all hidden errors</p>

Getting info out of an array as a variable
|
<p>Basically i'm trying to get some IPTC data from an image when a user uploads it. </p>
<p>Here's my code:</p>
<pre><code> $size = getimagesize($image_file, $info);
if(isset($info['APP13']))
{
$iptc = iptcparse($info['APP13']);
$iptc_description = $iptc['2#120'];
$caption = $iptc_description["0"];
var_dump($caption);
}
</code></pre>
<p>I did a var_dump, it dumps out:</p>
<blockquote>
<p>string(13) "caption data here blah blah"</p>
</blockquote>
<p>How can I get the $caption variable to just contain the caption data, without the string. I need the caption data as a variable so I can insert it into a db. </p>
<p>I don't really use arrays a lot so i'm a bit stuck! </p>

"this" in JavaScript
|
<p>I'm trying to understand the syntax of how to put together a JavaScript function as an object.</p>
<p>Q: Is this the right way to do it?</p>
<p>The reason why I ask is because I'm looking at it in Firebug and I was hoping to be able to drill down and see the value of myVar and myVariable, but instead Firebug only says that "this" is an object Object.</p>
<pre><code>var myObject = {
init: function() {
var myVar = 1;
myObject.myVariable = 2;
console.log('"this" when called as an object: ' + this);
}
}
myObject.init();
</code></pre>
<p>Also, what's the funny little syntax to call it directly upon declaration? Something about (), but when I remove the last line and put () at the end of the declaration, I get a syntax error.</p>

Programming for specific Android versions
|
<p>I have a question concerning Android programming. I intend to programm an application for Androiod 2.2 and above (including tablets). Problem, I am facing, is, that various version have different API news, e.g. Download Manager is fully implemented for the first time in 2.3, in 2.2 I have to programm it manually. I am thinking of building my app from modules, where each of them would be for particular Android OS version. You can imagine it as main app and depending on actual OS, it triggers Android 2.3 API Download Manager or (in case of 2.2) it starts my custom download manager, I have made. </p>
<p>Problem is, how to solve it in code? Because, when I enter to my 2.2 project .java file with Download manager import and code with it's usage, I cannot build application. I have found DexClassLoader solution, where I install only core of an app and other "modules" I will read from external sources depending on API level of current device. It sounds to me like "dirty" approach, isn't there anything "cleaner" how to solve particular pieces of code, which differs according to API level?</p>
<p>Thank ya</p>

Error received when updating the SDK with the SDK Manager
|
<p>I'm completely frustrated with the Android SDK Manager.</p>
<p>I'm running Win 7 Home edition and have the SDK installed in its own top level directory on my D:\ drive. </p>
<p>When I run SDK Setup.exe from the command line (and I've even opened the prompt as an administrator), I get an error when trying to update the packages.</p>
<p>The SDK manager is telling me that I need to install the SDK Tools rev 7. But when I accept the license, I get an error message stating:</p>
<p>"A folder failed to be renamed or removed" yada yada yada. The Installing Archives window says "Failed to rename directory D:\android-sdk-windows\tools to D:\android-sdk-windows\temp\ToolPackage.old01."</p>
<p>I looked here for help: </p>
<p><a href="http://groups.google.com/group/android-developers/browse_thread/thread/4b784f3eb1e096fd/ecadfb28ce5daf5f?lnk=gst&q=cannot+rename+folder#ecadfb28ce5daf5f">http://groups.google.com/group/android-developers/browse_thread/thread/4b784f3eb1e096fd/ecadfb28ce5daf5f?lnk=gst&q=cannot+rename+folder#ecadfb28ce5daf5f</a></p>
<p>but the content there didn't help.</p>
<ol>
<li><p>I DO have my antivirus (AVG) disabled.</p></li>
<li><p>I DO NOT have any other programs running -- just the command prompt to launch the SDK Manager.</p></li>
<li><p>I have even given the everyone group, for the D:\android-sdk-windows\ folder, full control.</p></li>
<li><p>I tried to rename the tools directory before starting the SDK Manager but then I get an error that a batch file cannot be found when I try to launch SDK Setup.exe. Grrrr.</p></li>
</ol>
<p>None of this works.</p>
<p>Suggestions how to get the package to update without error are greatly appreciated.</p>

Purpose of char in java
|
<p>I'm seeing both char and short are two bytes each,
also the following is valid:</p>
<pre><code>char a = 'x';
int b = a;
long c = a;
</code></pre>
<p>However when I do short d = a; I'm getting an error that cannot convert from char to short.
even though both are two bytes.</p>
<p>One use of char I can see is when you print it, it displays the character. Is that the only use of char?</p>

Is it bad form to return Arrays in C#? Should I return List<T>?
|
<p>I have a function which returns a variable number of elements, should I return an array or a List? The "collection's" size does not change once returned, ie for all purposes the collection is immutable. I would think to just return an array, but some people have said to not return variable sized arrays from a function as it is "poor form". Not sure why?</p>
<p>Does it matter that this needs to be .NET 2.0 compliant?</p>

Using PHP force download for all files
|
<p>My question is, is there a way to use the header download PHP method for all files type;</p>
<pre><code> <?php
$fileid = $_GET['fid'];
$filename = $_GET['fn'];
$auth_code = $_GET['dlauth'];
$folder = $_GET['fi'];
echo $file = $folder."/".$filename;
if (empty($fileid) || empty($filename) || empty($auth_code) || empty($folder)) {
echo "Malformed ID, please go back and try to download again";
} else {
if (strlen($auth_code) > 25) {
echo "Download session has expired or is malforned";
} else {
header("Content-Disposition: attachment; filename=$filename");
header('Content-Length: ' . filesize($file));
header("Pragma: no-cache");
header("Expires: 0");
readfile($file);
}
}
?>
</code></pre>
<p>Because this downloads zipped files etc, perfectly fine. However when it comes to anything else, it just corrupts.</p>
<p>Anyone got any clues without using switch statements to detirmine the content type with file extensions.</p>

PHP include practices
|
<p>Does anyone here know when PHP executes include and include_once calls?</p>
<p>I'm wondering because I come from a Flash and Desktop development background where you have to import your classes at the beginning of each class.</p>
<p>But now that I am starting to build more complex PHP code, it seems like it would be better to just include classes when I actually need them to save on loading time. For example, look at the following psuedo code:</p>
<pre><code>if (I_need_to_check_login)
{
include_once "Class.class.php";
$C = new Class();
}
</code></pre>
<p>If I do this, is the file Class.class.php going to be included everytime the code is run or only when I execute the include_once.</p>
<p>I'm a bit of a Class freak and usually build a class for just about any functionality used by my apps, so I often have lots of class files.</p>
<p>take care,

Why is my jQuery generated dropdown not posting back the selected value?
|
<p>I think I'm missing something simple, but I'm just not seeing it. I have an ASP.NET MVC app that is dynamically building a dropdown based on the value of another dropdown. The dropdown list is being populated correctly but when the form posts back the value of the combo isn't posted back for some reason. </p>
<pre><code> $(document).ready(function () {
PopulateList();
$("#List").change(GetSelectedItem);
});
function PopulateList() {
var timeSlot = $("#Timeslot").val();
var options = [];
var list = 0;
$.getJSON("GetList/" + timeSlot, "", function (data, textStatus) {
for (var i = 0; i < data.length; i++) {
options.push('<option value="',
data[i].ID, '">',
data[i].Name, '</option>');
}
$("#List").html(options.join(''));
if (data.length > 0)
list = data[0].ID;
GetSelectedItem(timeSlot, list);
});
</code></pre>
<p>Further down in the view I have this:</p>
<pre><code><% Html.BeginForm(); %>
<select id="List" style="width:120px"></select>
(lots of HTML removed)
<% Html.EndForm(); %>
</code></pre>
<p>I've double-checked the markup generated by displaying $("#List").html() and it looks OK. I've also checked to make sure the dropdown is enclosed in the form and that there isn't any other unterminated strings around this dropdown that might be interferring with it. I can check the value of the dynamically built dropdown and the value is set correctly. I've watched was is being posted back via Fiddler and Firebug and this field is missing (so it's not MVC filtering it).</p>
<p>What am I missing?</p>

Initialize MediaScanner at Beginning of Android Program
|
<p>I have an Android program that starts off by loading some of the user's media. Occasionally the program crashes -- both on an emulator and on an actual phone. I've found this is because sometimes media only become available to the program after the activity has been running for a while. </p>
<p>When this happens, here is the order of the typical log output:</p>
<ol>
<li>DEBUG/MediaScanner(166): opendir /system/media/ failed, errno: 2 <--PROGRAM ERROR HERE</li>
<li>DEBUG/MediaScannerService(166): done scanning volume internal</li>

<li>VERBOSE/MediaProvider(166): /sdcard volume ID: 45454545</li>
<li>VERBOSE/MediaProvider(166): Attached volume: external</li>
<li>DEBUG/MediaScannerService(166): done scanning volume external <-- THIS IS IN MIDDLE OF PROGRAM</li>
</ol>
<p>The program has an error at #1 because it tried to load media that wasn't available until #6.</p>
<p>Is there any way to force Android to finish the MediaScannerService at the beginning of the program?</p>
<p>Alternatively, is there any way to check when the MediaScannerService has finished scanning?</p>
<p>Thank you.</p>

How do I get rid of the "u" from a decoded JSON object?
|
<p>I have a dictionary of dictionaries in Python:</p>
<pre><code>d = {"a11y_firesafety.html":{"lang:hi": {"div1": "http://a11y.in/a11y/idea/a11y_firesafety.html:hi"}, "lang:kn": {"div1": "http://a11y.in/a11ypi/idea/a11y_firesafety.html:kn}}}
</code></pre>
<p>I have this in a JSON file and I encoded it using <code>json.dumps()</code>. Now when I decode it using <code>json.loads()</code> in Python I get a result like this:</p>
<pre><code>temp = {u'a11y_firesafety.html': {u'lang:hi': {u'div1': u'http://a11y.in/a11ypi/idea/a11y_firesafety.html:hi'}, u'lang:kn': {u'div1': u'http://a11y.in/a11ypi/idea/a11y_firesafety.html:kn'}}}
</code></pre>
<p>My problem is with the "u" which signifies the Unicode encoding in front of every item in my temp (dictionary of dictionaries). How to get rid of that "u"?</p>
