How to convert an H:MM:SS time string to seconds in Python?
|
<p>Basically I have the inverse of this problem: <a href="http://stackoverflow.com/questions/775049/python-time-seconds-to-hms">Python Time Seconds to h:m:s</a></p>
<p>I have a string in the format H:MM:SS (always 2 digits for minutes and seconds), and I need the integer number of seconds that it represents. How can I do this in python?</p>
<p>For example:</p>
<ul>
<li>"1:23:45" would produce an output of 5025</li>
<li>"0:04:15" would produce an output of 255</li>
<li>"0:00:25" would produce an output of 25</li>
</ul>

Jquery function works only one time
|
<p>here is a problem:</p>
<p>I need jquery to execute some php script and then return some results. There is a pagination at the page (generated by php). So there can be two cases. User gets to the page from external link => pagination starts from beginning. Or user selects a page => jquery runs php again and gets new pagination and results.
Here is a script:</p>
<pre><code>var page = '';
$.getJSON("test.php", {resid: "[[*id]]"}, function(output) {
$('#testdiv').html(output.content).show();
$('#pagination').html(output.pagination).show();
$('a.pagenav').click(function() {
page = $(this).attr('href');
$.getJSON("test.php", {resid: "[[*id]]", spp: page}, function(output) {
$('#testdiv').html(output.content).show();
$('#pagination').html(output.pagination).show();
});
return false;
});
});
</code></pre>
<p>The script works at inilial load (pagination gets generated) and then one time I select a page. But the next time I select a page, it just follows it's url.
Need help )
thx</p>

Doing thing 1
Doing thing 2

jQuery animations - when is asynchronous and when it's not?

<div id="sprite">

$("#sprite").animate({"width" : "1", }, 400 );
$("#character").animate({"width" : "1", }, 400 );
$("#character").animate({"margin-left" : "0", }, 400 );
</code></pre>
<p>However it seems that the first two animations execute simultaneusly while the third only starts when the others have finished.</p>
<p>Why is asynchronous in the first two but not with the third? How can I make the three of them run at the same time?</p>

PHP - How can I assign a name to my array key instead of an int with array_push

Data-structure to store "last 10" data sets?
|
<p>I'm currently working with an object Literal to store temporary information to send to clients, it's like a history container for the last 10 sets of data.</p>
<p>So the issue that I', having is figuring out the most efficient way to splice on object as well as push an object in at the start, so basically i have an object, this object has 0 data inside of it.</p>
<p>I then insert values, but what I need to do is when the object reaches 10 keys, I need to pop the last element of the end of object literal, push all keys up and then insert one value at the start.</p>
<p>Take this example object</p>
<pre><code>var initializeData = {
a : {},
b : {},
c : {},
d : {},
e : {},
f : {},
g : {},
h : {},
i : {},
j : {}
}
</code></pre>
<p>When I insert an element I need <strong>j</strong> to be removed, <strong>i</strong> to become the last element, and <strong>a</strong> to become <strong>b</strong>.</p>
<p>So that the new element becomes <strong>a</strong>.</p>
<p>Can anyone help me solve this issue, I am using node.js but native JavaScript is fine obviously.</p>

is there a Q&A formatted introduction to python similar to "the little schemer"
|
<p>EDIT: This should not have been closed, what I'm asking for (a Q&A formatted beginners intro to python) is more specific than still open questions such as "Online resources for Introduction to computer and computer sciences for absolute beginner", "What did you use to teach yourself python?" or "Python tutorial for total beginners?". The "debate" in the comments is not argumentative at all, just more background info.</p>
<p>I just looked at the first chapter of "The Little Schemer" and I love the idea of a Q&A format in an introduction to a programming language, is there anything like it in python? There's a sample chapter available at the amazon page if you're curious about what exactly the format looks like: <a href="http://rads.stackoverflow.com/amzn/click/0262560992" rel="nofollow">http://www.amazon.com/exec/obidos/ASIN/0262560992/ref=pd_sim_books/103-5471398-9229403</a>. (The reason I'm so excited about the Q&A format is that it's very convenient to put it into anki, a digital flashcard program.)</p>

Implementing queue in c#
|
<p>I am developing a c# application, in which the server gets requests from many clients at a time. Each client also gets their data from different databases. In this situation sometimes data leakage is happening, means clients get data from an incorrect database. Say for example client1 should get data from db1 and client2 gets data from db2. Instead they get data from opposite databases; client1 gets from db2 and client2 gets from db1.
I am adding the code below where it collects the data.</p>
<pre><code>public string List()
{
Response.ContentType = ContentType.Xml;
try
{
ThingzFilter filter = null;
Dictionary<string, string> parameters = new Dictionary<string, string>();
if (Id!="")
{
// get parameters from http request
foreach (HttpInputItem param in Request.Param)
parameters.Add(param.Name, param.Value);
setServerURLs();
//Request.Clear();
if (Request.QueryString["lang"].Value != null)
{
ThingzDB.TzThing.get_language = Request.QueryString["lang"].Value.ToString();
}
else
{
ThingzDB.TzThing.get_language = SessionDatabase.DefaultLanguage;
}
}
ThingzDatabase db = SessionDatabase;
langStr = db.Language;
// this is run if there was no ID supplied
// which means we want all items of all types
if (Id == "")
{
if (Request.AcceptTypes == null)
{
//TypeController.session_id = Request.QueryString["sessionid"].Value;
jobs.Add(Request.QueryString["sessionid"].Value);
if (nextJobPos > jobs.Count - 1)
return "";
else
{
TypeController.session_id = jobs[nextJobPos];
nextJobPos++;
langStr = SessionDatabase.Language;
}
filter = new AllThingzFilter(SessionDatabase, parameters, langStr);
TypeController.session_id = "";
filter.Execute();
}

LinkedList Part

<p>I think I might have done something right, headByRating and headByName both refer to the same address.</p>
<p>I have been drawing diagras working all day trying new things etc, and i havent really made any progress.</p>
<p>I have two list pointers, headByRating and headByName.
and two node pointers nextByName and nextByRating.</p>
<p>Somehow I need to be able to sort this stuff by its name and rating.
I've been thinking that I do that by each of the ptrs' address'.</p>
<p>2 statements as an example that I have been trying to sort:</p>
<pre>
//main.cpp
list *wineries = new list();
wineries->insert(winery("Lopez Island Vinyard", "San Juan Islands", 7, 95));
wineries->insert(winery("Gallo", "Napa Valley", 200, 25));
</pre>
<p>the winery ctor is fine everything is allocated and into the object at this point:</p>
<pre>
//list.cpp
void list::insert( const winery& winery )
{
list *listPtr = new list(); // havent really used the list obj. yet.
node *current = new node( winery ); // winery is now a node.
node *temp = current; // temp knows about the nodes address.
while ( temp->nextByName != NULL )
{
// check for null and reassign
temp = temp->nextByName;
}
node *new_node = new node( winery ); // creating a new node.
new_node->item = winery;
new_node->nextByName = new_node;
new_node->nextByRating = new_node;
}
</pre>
<pre>
// list.h
struct node
{
winery item;
node * nextByName;
node * nextByRating;
};
class list
{
...
private:
node * headByName;
node * headByRating;
};
</pre>
<p>What is a good approach to this? I dont think im doing this right. </p>

Creating dynamic labels not holding individual text

<p>I'm trying to create multiple instances of a user control on the page. I'm using labels to assign values to each control.
So from code behind I'm creating dynamic labels as:</p>
<pre><code>Label lblName = new Label();
lblName.ID = "lblName_" + entity.Id; // lblName_1, lblName_2, lblName_3, ...etc
lblName.Text = entity.Name;
this.Page.Controls.Add(lblName);
lblName.Style.Add(HtmlTextWriterStyle.Display, "none");
</code></pre>
<p>This is applied in the loop. But all the controls gets values of last instance of label; instead of individual.</p>

Add a row to UITableView for adding new item?
|
<p>In order to provide UI for user to add new items to my table view, I would like to add a new row in my table at a specified location (last row for example) when the view is in edit mode (I have a edit button on the view's navigation bar right side). This new row will have a add button indicator on the left side and disclosure accessory arrow on the right. When the view is not in edit mode, this add row should not be displayed.</p>
<p>I am not sure if I should overwrite:</p>
<pre><code>- (void)setEditing:(BOOL)editing animated:(BOOL)animated{...}
</code></pre>
<p>where I call the UITableView's method:</p>
<pre><code>insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:
(UITableViewRowAnimation)animation
</code></pre>
<p>to insert a new row?</p>
<p>My understanding is that this call may add a new row into the table view. The table view's data source is from CoreData storage. Not sure this may cause inconsistent numbers of data in the data store and table view? If it is OK and I have to manage rows in the table view, how can I add left add indicator and left disclosure arrow to the new row?</p>
<p>Another question is that if I can do it to insert a new row as Add row, should I remove it when the table view not in edit mode?</p>
<p>Just want to know if I am on the right track.</p>

How can I assign a call back function after I query something in javascript?
|
<p>I typically, call this to query back the result:</p>
<pre><code>db.transaction(function(tx) {
tx.executeSql('SELECT * FROM MyDB WHERE key = ?', [aKey], MyDB.renderResults);
});
</code></pre>
<p>and the renderResults function is like that:</p>
<pre><code>renderResults: function(tx, rs){
// for(i = 0; i < rs.rows.length; i++){
// document.getElementById("textfield").value = "";
// document.getElementById("textarea").value += rs.rows.item(i).chiChar;
// }
}
</code></pre>
<p>But I would like to make it more flexible, I would like to assign a function as a param to renderResults, in order to make my renderResult can execute a call back function. In other words,I would like to put the commented code into a function, which the renderResults only execute the function I put .....How can I do so ?? Thank you. </p>

Run program when cpu resources below percentage

<p>I want a program that I'm writing to execute on certain dates set by the user and also when CPU resources fall below a certain %. Right now, I am using Task Scheduler Managed Wrapper
(http://taskscheduler.codeplex.com/documentation) to set up a Windows Scheduled task with the date and time a user specifies. </p>
<p>However, I haven't been able to figure out how to do the CPU % part. Is it even possible to set up a Windows Scheduled Task to do this? If not, how would I do it? Windows service? </p>

How to reference the conents of a variable instead of a variable in Java
|
<p>Ok, I'm trying to make a quick double validator for any JTextField in a program. I would like to pass this to a function which then checks the contents of a field, makes sure it's a double, then return it as a double to the function. </p>
<p>Here is what I have so far but theTF.getValue() should get the value of the string, not the string itself. </p>
<pre><code> public double valDouble(String theTF)
{
double theDouble;
try
{
theDouble = theTF.getValue();
return theDouble;
}
}
</code></pre>
<p>How can I run the getValue() on the contents of the string?</p>
<p>Edit:
Ok, I somewhat screwed up my meaning. I understand the parseDouble, but I left it out on accident here is what I have now:</p>
<pre><code> public static double valDouble(String theTF)
{
double theDouble;
try
{
theDouble = Double.parseDouble(theTF);
}
catch(NumberFormatException e3)
{
theDouble = 0;
}
return theDouble;
}
</code></pre>
<p>My Real issue is theTF represents the name of a TextField. I need the value OF the text field not the value in theTF. I'd like to have this here to, perhaps, highlight the field red etc. </p>
<p><strong>Answer</strong>(Thanks Hunter):
The best way was to pass the Object, not sure why I was trying to parse out the value of a string reference. </p>
<pre><code> public static double vDbl(JTextField theTF)
{
double theDouble;
try
{
theDouble = Double.parseDouble(theTF.getText());
}
catch(NumberFormatException e3)
{
theTF.setText("Invalid");
return 0;
}
return theDouble;
}
</code></pre>

$_GET not working for querystring parameters in php
|
<p>I am having a problem with <code>$_GET</code> in one of my php script.</p>
<p>I am using an php script as a body for mail and I am uploading that script using a url. Everything was working fine when I was using only one parameter in query string.
When I used an array an converted it to query string using </p>
<pre><code>http_build_query($var1);

<p><a href="http://dev.thedoghouseps.com/mail_update_pet_info.php?id=1429&pet_id=1460&name=new&type=cat&breed=doberman2&dob=2009-02-16&sex=F&color=blue&vet_name=test&vet_phone=34%7C111%7C1111" rel="nofollow">url is</a>: </p>

</code></pre>
<p>Now problem is that I can not access the all the parameter except <code>id</code> and <code>pet_id</code>.
i.e. <code>$_GET['name']</code> is not giving me any value. But when I put this url directly on the navigation of browser then I am getting all the parameters except <code>pet_id</code>.</p>
<p>I have no idea now.</p>

Downloading big files and writing it locally

<p>which is the best way to download from php large files without consuming all server's memory?</p>

$cont = file_get_contents($url);
file_put_contents('./localfile',$cont);
</code></pre>
<p>This example loads entry remote file in <code>$cont</code> and this could exceed memory limit.</p>
<p>Is there a safe function (maybe built-in) to do this (maybe stream_*)?</p>

validating user session in php

<p>I am creating few pages (including login page) which should only be accessible by a sysadmin. </p>
<p>In login.php after the user's credentials have been verified. I set a session variable like so:</p>
<pre><code>mysql_connect("localhost", $values['uname'], $values['password']) or
die(mysql_error());
echo "Connected to MySQL<br />";
mysql_select_db("somedb") or die (mysql_error());
session_start();
$_SESSION['level'] = 'admin';
header('Location: /admin/index.php');

<pre><code><?php
if($_SESSION['level'] !== 'admin'){
header("location:../admin/login.php");
}
?>

<p>But it does not seem to work. Everytime I am being redirected to login.php (even after successfully logging in via login.php).<br />

different themes in portrait and landscape for a ListView
|
<p>I have a ListView which should have the "Theme" theme in portrait and the "Theme.Light" theme in landscape mode. How do I do that? The theme seems to be tied to the activity, and for the ListView I can only change the style, but I dont find a style which works.</p>
<p>Or, is there a way to change the activity's theme based on orientation? By code or prefereable by xml?</p>
<p>To be more precise and explain the reason: I try to start experimenting with the fragment compatibility library. The starting activity shows in portrait mode a list which looks best with black background. When I touch a list item, a second Activity starts and shows a ListView which better looks on white, so this second Activity has the Theme.Light. Works so far.</p>
<p>When I switch to landscape, I try to show both ListViews aside. The second one on the right <em>has</em> to have a white background. The first one on the left could stay on white also (so the whole activity could change the theme), but I'd like to see one on black and one on white, if possible. (I put both ListViews in Fragments, this is done and works. Only the colors are wrong.)</p>
<p>Any ideas?</p>

Issue with a php form
|
<p>I've created a very basic php form for a website and the form mostly works - only problem is that when the form is emailed to the gmail account, only one line (the "college" line) shows up in the email, with the rest blank. The sender's name ($field_name) appears in the subject line of the message (along with the xxx.Org TShirt Order part of the message), but the only line that appears in the body of the message is the "college part".</p>
<p>Here's the code (I'm aware that it's not sterilized... I'm really new to php and I don't feel like I've got a handle on the language yet, so I'm starting really basic):
<pre><code>$mail_to = 'xxx@gmail.com';
$subject = 'xxx.Org TShirt Order - '.$field_name;
$body_message = 'From: ' . $field_name . "\n";
$body_message .= 'E-mail Address: '.$field_email."\n";
$body_message .= 'Quantity of Shirts: '.$field_quantity."\n";
$body_message = 'Shirt Style(s): '.$field_which."\n";
$body_message .= 'Size(s): '.$field_size."\n";
$body_message .= 'School: '.$field_school."\n";
$body_message = 'College: '.$field_college."\n";
$headers = 'From: '.$field_email."\r\n";
$headers .= 'Reply-To: '.$field_email."\r\n";
$mail_status = mail($mail_to, $subject, $body_message, $headers);
if ($mail_status) { ?>
<script language="javascript" type="text/javascript">
alert('Thank you for placing an order with xxx.Org. We will contact you shortly.');
window.location = 'contact_page.html';

<?php

<p>Very strange in that I would have no problem using settimeout on a simple function, but I am kind of stumped in this seemingly more simple situation.</p>
<p>My thought would be I could just make a function that calls that file after x amount of time, but calling the file in the function seems to be escaping me.</p>

How To detect the UItable Section

_multipart.addBodyPart(messageBodyPart);
}
</code></pre>
<p>I call this function when attaching images to email.
When I try to remove the attachment it is not possible.</p>
<pre><code> public void removeAttachment(String filename) throws Exception {
BodyPart messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
_multipart.removeBodyPart(messageBodyPart);
}
</code></pre>
<p>Tried with this function but not working.</p>
<pre><code> public void AddAndRemoveAttachment(String filename, Boolean yesorno)throws Exception{
BodyPart messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename);
if(yesorno == true ){
source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
_multipart.addBodyPart(messageBodyPart);
}
else{
_multipart.removeBodyPart(messageBodyPart);
}
}
</code></pre>
<p>But the removeBodyPart is not removing the attached image.
Looking forward to your reply.
thanks.</p>

Why does one of my values change?
|
<p>So I have this;</p>
<pre><code>var emailA = ConstructEmailA();
SnedEmailA(emailA.Append("</body>").ToString());
var emailB = ConstructEmailB(emailA);
SendEmailB(emailB.ToString());
</code></pre>
<p>Which works fine. Essentially, ConstructEmailB takes emailA and adds to it. However, I originally had this:</p>
<pre><code>var emailA = ConstructEmailA();
var emailB = ConstructEmailB(emailA);
SnedEmailA(emailA.Append("</body>").ToString());
SendEmailB(emailB.ToString());
</code></pre>
<p>Which did not work as expected. Instead of emailA and emailB being different, emailA contained the same info as emailB. How come?</p>
<p>Here is my ConstructEmailB method:</p>
<pre><code>private StringBuilder ConstructEmailB(StringBuilder email)
{
email.Append("Append stuff");
return email;
}
</code></pre>

Locally served javascript shows inheritance chain in console, remotely served does not?
|
<p>Recently noticed the below. Locally served page is on top, remotely served is on bottom. Curious as to what would cause this. My settings for chrome dev tools is identical. My guess would be local is showing the full inheritance chain and remote does not, but some other developers in my office don't see the same for their local setups. Any ideas? <img src="http://i.stack.imgur.com/DMgFm.png" alt="enter image description here"> </p>
