The script will find if a program has an icon on the desktop. If it has then my script will change the size of that with imagemagick.

I find that native apps are a lot smoother when it comes to animations. I've also found that moving from page to page on a native app is a lot faster because most of the UI is on the device so the amount downloaded is a lot smaller.
The path app has some beautiful animations and the UX is very nice. I'm not sure this app would be as good if it wasn't a native one.
I havn't come across any really nice mobile web apps. There are some good frameworks out there. I have used jQuery mobile and while it seems good, I think it still has some work to be done to get it really useful.
So my question is:
**What do you think the main pros/cons of a mobile web app are compared to a native ios app?** | ios | html5 | web-applications | mobile | null | 06/30/2012 05:54:06 | not constructive | The pros and cons of a mobile web app vs a ios native app
===
I'm trying to compile a list of the pros and cons of a mobile web app vs a native app.
I find that native apps are a lot smoother when it comes to animations. I've also found that moving from page to page on a native app is a lot faster because most of the UI is on the device so the amount downloaded is a lot smaller.
The path app has some beautiful animations and the UX is very nice. I'm not sure this app would be as good if it wasn't a native one.

Now the confirmation box works well. The only problem I can see is that when the user clicks 'OK' I want the INSERT VALUES to happen on a seperate page (insertQuestion.php) but I do not want the form to be navigated to that page. I want the form to navigate the way it is doing which is either submit to its own page or submit to create_session2.php depending on the situation.
So how can I INSERT VALUES into the database without navigating the user to that page (insertquestion.php) after the user has clicked 'OK' in the confirmation box?
I have tried using Jquery to perform an AJAX request but this has failed (Code of Jquery is at the bottom)
below is the javascript code where the confirmation box appears and if confirmation is 'OK', it submits the form:
function showConfirm(){
var confirmMsg=confirm("Do you want to Proceed" + "\n" );
if (confirmMsg==true)
{
submitform();
}
}
function submitform()
{
var QandAO = document.getElementById("QandA");
QandAO.submit();
}
Below is the INSERT VALUES code (already connected to DB and is on insertQuestion.php page wile the values posted are from the previous page):
$insertquestion = array();
for ($i = 1, $n = $_POST['sessionNum']; $i <= $n; ++$i)
{
$insertquestion[] = "' ". mysql_real_escape_string( $_POST['id'] ) . ($n == 1 ? '' : $i) . "'";
}
$questionsql = "INSERT INTO Question (SessionId)
VALUES (" . implode('), (', $insertquestion) . ")";
mysql_query($questionsql);
</script>
My Attempt on Jquery which has failed (doesn't show alert so it doesn't reach insertQuestion.php page meaning values are not inserted into DB):
$("#submitBtn").click(function() {
var fieldvalue = $("#QandA").val(); //grab the form value
$.post("insertQuestion.php", //send it to yourpage.php
{
field1: fieldvalue

Each of the tile cell is a small BufferedImage element. Day and night cicles are implemented by modifying the pixels of these images (darkening and blue shifting), then a window-light map (another static BufferedImage) is rendered over each building. The proper Z-order is kept by going in top-right-bottom-left order and only strips of the tiles are drawn. Unfortunately, this approach practically destroys the acceleration of the images and the rendering becomes very slow if the day-night transition happens on very fast game speed. The current solution is to cache a number of shades for each tile at the cost of huge memory increase.
Can the Java [composition modes][2] of Graphics2D used for this purpose, e.g, draw the normal colored tile, draw a darkened surface over it, then apply the light-map? How can I ensure that only the pixels of the normal tile are affected by the recoloring?

[blocks] => Array (
[testchild] => Array ( [name] => testchild [module] => admin [helper] => [model] => [data] => [parent] => subhead
)
)
)
)
)
-- Basically, Blocks have children which are wrapped within the parent block. Im trying to figure out an effective way to manage the levels as right now I am using a separate function to output the children blocks, and if I wanted to be able to go 3 levels deep, I would have to create yet another function. So I am trying to do it recursively, by dynamically adding an array key to my for each statement each time the function reiterates.
For example, this is the function I am using to output the blocks --
function outputChildBlocks($view_name)
{
if(isset($this->view_data[$view_name]['blocks']))
{
$html='<div class="blockWrapper">';
foreach($this->view_data[$view_name]['blocks'] as $block)
{
$html.= '<div class="block '.$block['name'].'">';
$module = $block['module'];
$name = $block['name'];
$data['block'] = $block;
if($block['helper'] != null)
{
$this->load->helper($module.'/'.$block['helper']);
}
if($block['model'] != null)
{
$data['model'] = new $block['model']();
}
$html .= $this->load->view($module.'/blocks/'.$name, $data, true);
if(isset($block['hasChildren']))
{
$html .= $this->outputChildChildBlocks($view_name, $name);
}
$html.= '</div>';
}
$html .= '</div>';
return $html;
}
}
As you can see, at the bottom I am checking if parent has children, and if it does, I call a completely seperate function to output the child blocks (outputChildChildBlocks) -- So, instead, I would like to have the function recognize the depth of the current location, and when it gets to the if statement at bottom, if it does have children, run itself again, add a counter for each level, and then instead of
foreach($this->view_data[$view_name]['blocks'] as $block)
have it go
foreach($this->view_data[$view_name]['blocks'][$name]['blocks'] as $block)
for the 2nd level, then go
foreach($this->view_data[$view_name]['blocks'][$name]['blocks'][$name]['blocks'] as $block)
for the 3rd level, so on and so forth.
Anyways I am not sure how to dynamically add the ['blocks'] key on to the array, for every iteration of the function that has been run for that main block... (obviously I have a [footer] and a [content] block and what not as well with their own sets of blocks)
Anyways sorry if I over explained or complicated the question I have a tendency to do that but I am trying to be as clear as possible and I will be eternally indebted to you if you can show me the best way of making this function recursive!

My WebSite, at design-time references the assembly with a Project Reference and Visual Studio automatically populates the Toolbox with the controls found in my class library.
The problem is : When I drag them to the ASPx designer, Visual Studio automatically creates a TagPrefix ignoring the my class library's strong key. This is a problem for me because when I publish this website, this class library will be the Global Assembly Cache and it won't be found if the TagPrefix doesn't properly reference it.

However, the whole area is new to me (I'm more of an embedded developer dabbling). And frustratingly, every tutorial I am trying in Php is either out of date, not doing what it claims to do, it or is broken.
Essentially, I just want a nice bit of example code - say, an HTML file, a connection.js for the JQuery magic, and a php file - 'getsearch' which contains the relevant Curl calls to the API to just return the results for a given search term.
Followed the tutorial to the letter at

and even downloaded the guy's code and chucked it on my webserver, but it just seems to sit there.
I'm relatively competent at php and html, but it's the Curl and the JQuery side of things which is new to me, and would appreciate any thoughts, links, or code suggestions. I've attempted reading the API - but even that seems sparse - and several links are broken to their own tutorials, so that's put me off a bit for now. | twitter | php | curl | jquery | javascript | null | open | Getting search results from Twitter in php

I would've thought that 0x01001010 == 1010100 (Note: the fprintf is using %x as output format, so I am looking at a hexadecimal number. Also, when I test and use a printf with %d output format, I see the value 16843008 (= 16^6 + 16^4 + 16^2), which is the equivalent decimal representation of 0x01010100. The 'bad value' 1010100 output is not affected by the presence of my printf checking statement).
How can I make sense of the fact that the switch statement does not recognize 1010100 as the next to last case (i.e.case 0x01010100: a = 0xe0)?

I am writing this to walk through the logic of the program step by step and verify why it returns the output that it does. I would appreciate any feedback on the way I'm interpreting this.
I'll display the program first, and then explain how it works afterwards.
public class Test9 {
public static void main (String [] args) {
int x=0;
int y=10;
for (int z=0; z<5; z++) {
if((y-->7) || (++x >2)) {
y--;
}
}
System.out.println(y + "" + x);
}
}
What is the output and why?
In order to know the correct output of this program, it's necessary to keep a running tally of all three int variables, x, y, and z, during the course of the "for" loop.
At the beginning of the loop, z=0, x=0, and y=10.
It then proceeds to the if statement, where it looks to see if the current value of y is greater than 7. It's important to note that y-- means that it will post-decrement y by 1. Which means AFTER the conditional statement has been been decided True or False.
So, since y=10, currently, 10>7, and the statement is True. Since this conditional statement is true and it sees that an OR operator is next, it skips the ++x>2 since it doesn't need to know whether it is TRUE or FALSE. The contents of the loop are now performed, y--, which makes y=8. Decremented once in the conditional statement and once inside the if statement. x remains 0.
The next iteration begins with, z=1, y=8. x=0. The same rules apply, so 8>7, y will be decremented by 2 and x will remain the same.
The third iteration begins with z=2, y=6, x=0. This time around, 6>7 is false, but y is still post decremented. So y=5, and ++x>2, will evaluate as 1>2, since ++x is the prefix version and adds 1 before the operation takes place. Both operations are false, and y will not be decremented a second time.
The forth iteration begins with z=3, y=5, x=1. 5>7 is false, y is decremented to 4. 2>2 is false as well, therefore no 2nd decrement to y.
The fifth iteration begins with z=4, y=4, x=2. 4>7 is false, y is decremented to 3. 3>2 is true! So y will be decremented a 2nd time, to 2.
The ending values are y=2, x=3. Therefore the program output will be:
2 3
It's important to understand when the increments and decrements happen and when they don't, especially when they are inside the conditional statements of an if statement, since it will impact the final output.
