If I run the code on my phone galaxy s2 2.3.6, it works fine. However, if I try to run on eclipse emulator, it will give me an error. :(

What the code does is simple viewflipper.

I tried to run on emulator platform 2.3.3 and 4.0.3

Thank you for the help.

bottom is the logcat output.

Yes, I have goggled this question and even referred to my textbook (PHP by Don Gosselin) but I seriously cannot understand the explanations :-( (I feel dumb)

From my understanding:

echo = shows the final result of a function

return = returns the value from a function

I applied both echo and return in the following functions I cannot see the difference or the 'effectiveness' of using return instead of echo.

<?php
echo "<h1 style='font-family:Helvetica; color:red'>Using <em>echo</em></h1>";
function add1($x, $y){
    $total = $x + $y;
    echo $total;
}
echo "<p>2 + 2 = ", add1(2, 2), "</p>";

echo "<h1 style='font-family:Helvetica; color:red'>Using <em>return</em></h1>";
function add2($x, $y){
    $total = $x + $y;
    return $total;
}
echo "<p>2 + 2 = ", add2(2, 2), "</p>";

?>

Both display the result! What am I not understanding? :(

Please bear with me!

I've been learning Objective C lately, and I came across some code for using the accelerometer in an iPhone app. It works perfectly; however, there's one if-statement in the code which I simply cannot understand (both the meaning and why it works). The specific chunk is this:

if (0.2f < deviceTilt.y > -0.2f){position.x = 0;}

I just can't figure out the condition, and I hadn't seen the use of two comparison operators in one single clause before.

Hope somebody can help me out!

Hey guys I'm trying to see where my pairs of keys stop, I have arrays built like this

EDIT People are getting really confused so I'm using a real array instead of an example

array (
  'key' => '',
  'po' => '',
  'label' => '',
  'report_key' => '',
  'shipper' => '',
  'status' => '',
  'location' => '',
  'inspector' => '',
  'commodity' => '',
  'brand' => '',
  'case_count' => '',
  'variety' => '',
  'style' => '',
  'grower_lot' => '',
  'pack_date' => '',

  // grouping 4 items
  'berry_size1' => '',
  'berry_size2' => '',
  'berry_size3' => '',
  'berry_size4' => '',

  // grouping 3 items
  'bunch_color1' => '',
  'bunch_color2' => '',
  'bunch_color3' => '',

  // grouping 2 items     
  'color1' => '',
  'color2' => '',


  // grouping 3 items
  'stem1' => '',
  'stem2' => '',
  'stem3' => '',


  // grouping 2 items
  'shatter1' => '',
  'shatter2' => '',


  // grouping 2 items
  'splits1' => '',
  'splits2' => '',


  // grouping 2 items
  'wet_sticky1' => '',
  'wet_sticky2' => '',

  'overall_quality' => '',


  // grouping 2 items
  'sugar_brix1' => '',
  'sugar_brix2' => '',

  'rating' => '',
  'comments' => '',
)

I came up with some stupid way that really doesn't work to try and sort things out, its extremely backwards, honestly I'm pretty embarrassed by my attempt.

            foreach($obj as $key=>$val) {

            if(strpos(  preg_replace('/[^a-z]/i', '', $key), 
                        preg_replace('/[^a-z]/i', '', $all_keys[$key+$b+1])
                        ) !== false) { echo "<p>$key</p>"; // items 1-3 will show
            } elseif(strpos(preg_replace('/[^a-z]/i', '', $key), 
                            preg_replace('/[^a-z]/i', '', $all_keys[$key+$b-1])
                            ) !== false) { echo "<p>$key</p>"; // show last item
            } else {

                  $in.='<aside class="left">';
                    $in .= "<label for='$key'>". ucwords(strtolower(str_replace('_',' ',$key))) ."</label><br/>";
                    $in .= ($key=='key') ? "<input type='text' value='". $objLastId ."' id='$key' class='disabled' disabled='disabled'>" : "<input type='text' value='' name='$key' id='$key'>";
                  $in.='</aside>';

              $b++;
              }
            }

Anyway what I'm really trying to achieve is something like this, could someone steer me in the right direction please?

<style>
 .row2 input {width: 50px !important;}
 .row3 input {width: 27px !important;}
 .row4 input {width: 15px !important;}
</style>

// stem was a 2 item group, so should have the row4 class
// and should have the second item appended by a &nbsp; 
// all be inside the same grouping, like below ...
<aside class="left row2">
<label for="color1">Color</label>
<br/><input type="text" value="" name="color1" id="color1">
&nbsp;<input type="text" value="" name="color2" id="color2">
</aside>


// stem was a 3 item group, so should have the row4 class
// and should have items 2-3 appended by a &nbsp; all be inside 
// the same grouping, like below ...
<aside class="left row3">
<label for="stem1">Stem</label>
<br><input type="text" id="stem1" name="stem1" value="">
&nbsp;<input type="text" id="stem2" name="stem2" value="">
&nbsp;<input type="text" id="stem3" name="stem3" value="">
</aside>


// berry_size was a 4 item group, so should have the row4 class
// and should have items 2-4 appended by a &nbsp; all be inside 
// the same grouping, like below ...
<aside class="left row4">
<label for="berry_size1">Berry Size</label>
<br/><input type="text" id="berry_size1" name="berry_size1" value="">
&nbsp;<input type="text" id="berry_size2" name="berry_size2" value="">
&nbsp;<input type="text" id="berry_size3" name="berry_size3" value="">
&nbsp;<input type="text" id="berry_size4" name="berry_size4" value="">
</aside>

... or ...

// this is a single, so no extra class and ....
<aside class="left">
<label for="other_item">Other Item</label>
<br/><input type="text" id="other_item" name="other_item" value="">
</aside>

What I see this really boiling down to is reading the next array keys name (I stripped the name and used the integer in my version), atleast I think that's the right way to do it?

On a spark text area in my Flex Mobile project, I want to only allow upper and lowercase letters, numbers and only some symbols. It works fine except now when someone hits the return key it doesnt do a line break like it naturally would. is there something I need to add to my restrict to allow line breaks?

so i tried this in the MXML of the Text Area:

restrict="a-z A-Z 0-9 !@#$%()"

and this restrict="a-z A-Z 0-9 !@#$%()\n"

Just to be clear, I'm on a 'Mobile' project, and testing without restrict on my Nexus one, using the touch screen keyboard, if i hit return it works fine, and does the line break.

but, as soon as I do restrict="a-z A-Z 0-9 !@#$%()" the return key does not work like it should.
