Shopping basket in PHP PDO model
|
<p>Hello I want to create a shopping basket in PHP with PDO model and MVC architecture.
I have two tables</p>
<pre><code>Products [product_id , product_price , product_name ..etc]
Basket [basket_id, product_id, basket_quantity]
</code></pre>
<p>My problem is that I have two classes <code>Product()</code> and <code>Basket()</code> with the relevant constructors and get methods (<code>getProductPrice()</code>, <code>getBasketId()</code> ..etc).</p>
<p>So in the <strong>basket.php</strong> page I have </p>
<pre><code>$database = new BasketTable();
foreach ($view->basketList as $product) : {
$subTotal += ($product->getProductPrice()) * ($product->getBasketQuantity());
}
</code></pre>
<p>The thing is that in the method <code>getProductPrice()</code> doesn't exist in <code>BasketTable()</code>. So, do I have to add another foreach and create other variable (eg <code>$database2 = new ProductTable()</code>) ?</p>

jQuery slideToggle variable duration

var iNum = $(this).prevAll('.list_category:first').length();
var tNum = iNum*100;

string remove between start string and end string
|
<p>I find this concept is the same as what I need:-</p>
<p><a href="http://stackoverflow.com/questions/16334442/remove-character-starting-with-x-and-ending-with-x-and-everything-between-it-in">Remove character starting with x and ending with x and everything between it in a string.</a></p>
<p>would there be similar function in php? also, is it possible to do replace all such cases in a long string?</p>
<p>example:
$text = "
<code><h2 class="active" tabindex="0" rel="120">Title 2</h2><h2 class="active" tabindex="0" list="20" rel="120">Title 2</h2><h2 class="active" tabindex="0" rel="120">Title 2</h2></code>";</p>
<p>Here, I wish to detect class="active", and the ">" of <code></h2></code>, the remove any changing contents between.</p>

Density on Android
|
<p>I'm trying to render custom buttons in Android. However, I'm having issues getting my bitmaps to render without scaling. I have a few constraints that are forcing me to forgo a few possible solutions. First, my bitmaps are being generated using a byte array through BitmapFactory; which I'm passing in bitmap options that specify inScaled=false for that. Second I must do everything in code, and am unable to use layout XML.</p>
<p>When I go to draw my custom button (which extends View), along with using the default behavior, I've tried calling <code>setDensity</code> on the canvas with both DENSITY_NONE and <code>bitmap.getDensity( )</code> (which is 160.) Despite this I can't get the bitmaps to render without scaling up. I've tried setting more options when creating my bitmaps (such as target density, screen density, etc.) However no combination of these has worked. This code 'fails' on the Samsung Galaxy S running 2.1 as well as HTC Droid Incredible on 2.1. When testing on an HTC Hero running 1.5 things work, but that was before the density stuff:/</p>
<p>Anyone out there have a suggestion?</p>
<p>Thanks!</p>
<p>Update:</p>
<p>I was a bit miss guided with my problem. It seems that the issue is with the underlying view. If I try to draw a normal line, I get scaling as well. This only happens in landscape, not portrait. Is there any way to disable the scaling between the two orientations?</p>

Code works in one Android project but won't compile in another
|
<p>The following code was copied from project one and pasted into project two. No errors in project one. In project two I get: </p>
<blockquote>
<p>The method <code>onClick(View)</code> of type <code>new View.OnClickListener((){}</code> must override a superclass method
implements <code>androd.view.View.OnClickListener.onClick</code></p>
</blockquote>
<p>The project settings look the same, but I must be missing something.</p>
<pre><code>private Button mCompany = null;
public class About extends Activity{
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.about);
setTitle(R.string.title_about);

Accessing secure websites via App
|
<p>If my app provides a link to a secure website eg a booking system that uses https etc, then are the user's credit card and password details secure in this case ie are the card and password details encrypted when being sent from the mobile phone ?
Also do you need the permssion of the website owner to incorporate such a link into your app. I would have thought the anser is no as it is a publically available website, but I just wanted to make sure.
Thanks very much

Initiate a scoped function from a string in javascript
|
<p>Lets define a dog:</p>
<pre><code>function Dog() {}
</code></pre>
<p>Now lets define a self executing function that passes the Dog as a parameter:</p>
<pre><code>(function(dogClassName) {
var someServerSideLogicResolvesClassName = "dogClassName";
//Iniate class name from the server side string
})(Dog);
</code></pre>
<p>After some googleing I found that I should use</p>
<pre><code>new window["dogClassName"]();
</code></pre>
<p>or</p>
<pre><code>new this["dogClassName"]();
</code></pre>
<p>But since it's a scoped variable it doesn't exist in the global name space (no window) and <code>this</code> is <code>undefined</code>; I have no idea how to achieve this without using some sort of evaling. </p>

Function to create new, previously undefined variable

<p>Sorry for such a lame title, but I just had no idea what to put there, hope you understand it. Plus, I have no idea if similar question has been asked before, because I don't know the proper keywords for it - therefore couldn't google it too.</p>
<p>Basicly... When looking at <a href="http://php.net/manual/en/function.preg-match-all.php" rel="nofollow"><code>preg_match_all();</code></a>, they got this <strong>matches</strong> parameter that will create new array defined in function, and give us the ability to access it after function execution.</p>
<p>And the question is.. How can I implement such a feature in my own function? But that it could create single variable and/or array.</p>

mb_substr adds 3 dots(...) at the end when stripping UTF-8 text, and doesn't add them when the text is in latin
|
<p>I have a code like this:</p>
<pre><code>if(strlen($text)>=15)
$text=mb_substr($text, 0, 15, 'UTF-8');
</code></pre>
<p>It works as it should, but the thing is, when the text is in Latin(e.g. English), when it strips it down, it does not display 3 dots in the end. On the other hand when the text is in other languages that need UTF-8 encoding it adds 3 dots in the end.</p>
<h2>Example:</h2>
<blockquote>
<p>What are cells made of</p>
</blockquote>
<p>gets replaced with </p>
<blockquote>
<p>What are cells </p>
</blockquote>
<p>On the other hand:</p>
<blockquote>
<p>で作られた細胞は何ですか</p>
</blockquote>
<p>gets replaced with </p>
<blockquote>
<p>で作られた細 ...</p>
</blockquote>

How To Handle UIImage on device rotation
|
<p>I have a UIScrollView with a UIImage inside. The following code initializes the image properly (it's width is the same as the width of the scrollView):</p>
<pre><code>// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
...
imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"map1.jpg"]];
imageView.userInteractionEnabled = YES;
imageView.autoresizingMask = ( UIViewAutoresizingFlexibleWidth );
[imageScrollView addSubview:imageView];
imageScrollView.contentSize = [imageView frame].size;
...
// calculate minimum scale to perfectly fit image width, and begin at that scale
float minimumScale = [imageScrollView frame].size.width / [imageView frame].size.width;
//imageScrollView.maximumZoomScale = 1.0;
imageScrollView.minimumZoomScale = minimumScale;
imageScrollView.zoomScale = minimumScale;
}
</code></pre>
<p>What I want to do is to set the size to perfectly fit (like above) when the device rotates. Here's what I've tried to do:</p>
<pre><code>- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
float newScale = [imageScrollView frame].size.width / [imageView frame].size.width;
imageScrollView.zoomScale = newScale;
}
</code></pre>
<p>For some reasons this doesn't work at all. The only way that I was able to make it work was to initialize another UIImage and do all the initialization process again, which doesn't feel right to me.</p>

Adding items to empty List at specific locations in java
|
<p>Is there any way I can make the below code work without commenting the 3rd line.</p>
<pre><code> List<Integer> list = new ArrayList<Integer>();
list.add(0,0);
//list.add(1,null);
list.add(2,2);
</code></pre>
<p>I want to add items to list at specific locations. But if I don't change the index to Nth position I am not being able to add at Nth as told in this <a href="http://stackoverflow.com/questions/2534413/index-out-of-bounds-error/2534454#2534454">answer</a>.</p>
<p>I can't use a map because I don't want to miss a value when the keys are same. Also adding null values to a list for large lists will be an overhead. When there is a collision I want the item to take the next position(nearest to where it should have been). </p>
<p>Is there any <strong>List implementation that shifts index before it tries to add the item</strong>?</p>

Bookmarklet not working as it should (i think)

<p>Can someone tell me what I am doing wrong here...</p>
<p>This returns "Button Not Found"</p>
<pre><code>javascript:var nam="http://apps.facebook.com/onthefarm/giftaccept.php?senderId=547766125&amp;gift=haitibackpack_item_single&amp;timestamp=1285776944&amp;ref=gift_accept_tab&amp;key=6870697de39960508737349c7a3f1363%24%24ggM3T%2CPU2YKM2l0mNrM%28U%28b%21eHAoclFCBgwg49%21S34GWkEXxTekFN_Fkx5%2AUZPcNMEOj&amp;signature=a86a9e11aab0051e3fde676a9abe4283&amp;srcapp=FarmVille"; nam="actions["+nam.replace(/\&amp;/g, "&")+"]"; var els=document.getElementsByName(nam); if(els.length == 0) alert("Button not found"); else els[0].click();
</code></pre>
<p>This prompts me to enter a URL...I enter the EXACT same URL as in the above example and it works fine, clicks the button which brings me to the desired page. </p>
<pre><code>javascript:var nam=prompt('enter URL Please'); nam="actions["+nam.replace(/\&amp;/g, "&")+"]"; var els=document.getElementsByName(nam); if(els.length == 0) alert("Button not found"); else els[0].click();
</code></pre>
<p>Thanks</p>
<p>Before you ask...I've tried in Chrome, IE and Firefox. It does not appear to be an issue with the length of the JS. I get the same results as above regardless of which (valid) URL I use. I am getting desperate here.</p>

slow php command line performance - is this normal or do I have an install problem?
|
<p>I have a simple PHP app that prints 'hello world'. When I run it from the command line it takes 6 seconds. Is this normal? It seems to take 1 seconds before "hello world" prints, then 5 seconds after.</p>
<p>I am running PHP version 5.2.12 on Windows Server 2008 R2. Could this be an install issue, or is it typical? I did a manual install of PHP then added whatever components were needed to run Drupal. The only PHP addon I remember adding was MDB2, CGI support is there too.</p>
<p>I am used to a Lua project I run from the command line, hundreds of lines of code that will run in under a second.</p>
<p>I have some unit tests I run from the command line, and already with just a few they are very slow. I run them from Netbeans and the tests are still very slow.</p>
<p>I run precisely this:</p>
<pre><code>C:\temp>copy con test.php
<?php
print('hello, world');
^Z
1 file(s) copied.
C:\temp>test.php
hello, world

PHP creates corrupt thumnbail

<p>I created a test page of site and you can see it here: <a href="http://jm-ai.com/test/index.html" rel="nofollow">http://jm-ai.com/test/index.html</a></p>
<p>I'm using a sprite image for the normal, hover, and active state.</p>

How to test with Python if str variable contains number (int,float) or non-numeric str
|
<p>If a Python string variable has had either an integer, floating point number or a non-numeric string placed in it, is there a way to easily test the "type" of that value?</p>
<p>The code below is real (and correct of course):</p>
<pre><code>>>> strVar = "145"
>>> print type(strVar)
<type 'str'>
>>>
</code></pre>
<p>but is there a Python function or other method that will enable me to return 'int' from interrogating strVar set as above</p>
<p>Perhaps something like the nonsense code and results below ...</p>
<pre><code>>>> print typeofvalue(strVar)
<type 'int'>
</code></pre>
<p>or more nonsense:</p>
<pre><code>>>> print type(unquote(strVar))
<type 'int'>
</code></pre>

jQuery - Toggle div class on click
|
<p>No, this is not a straight forward toggle question. I am aware of the toggle() functions and how to simply hide/show a div. Imagine a box with a label inside:</p>
<pre><code><div class="section hidden">
<div class="section-legend">My Section</div>
</div>
</code></pre>
<p>When you click anywhere on the entire div, it should remove class <code>hidden</code>. The box then looks expanded. Now that the box is not of class <code>hidden</code> it should not be clickable.</p>
<p>Instead, when you click the <code>div.section-legend</code> it should add class <code>hidden</code> to the main div again. Obviously the click event for the legend needs to stopPropagation(). Now the legend should not be clickable anymore and once again you must click the entire div to open it.</p>
<p>I can't get anything to work properly, and I know this is stupid code:</p>
<pre><code>$(document).ready(function() {
$('.section.hidden').click(function() {
$(this).removeClass('hidden');
$(this).find('.section-legend').click(function(e) {
$(this).parent().addClass('hidden');
e.stopPropagation();
});
});
$('.section-legend').click(function(e) {
$(this).parent().addClass('hidden');
e.stopPropagation();
$(this).parent().click(function() {
$(this).removeClass('hidden');
});
});
</code></pre>

would it ever make sense to modify a reference to a const char* passed in as a parameter to a method?
|
<p>Say I have something along the lines of:</p>
<pre><code>int main()
{
const char* someString = "Hello";
MyClass myClass;
myClass.modifySomeString(someString);
return 0;
}
</code></pre>
<p>And two possible method signatures for <code>modifySomeString</code>:</p>
<p><strong>case A</strong> <code>void MyClass::modifySomeString(const char* inBuffer)</code></p>
<p>This seems straight-out pointless since I'd be getting a value so whatever I do with inBuffer does not affect the original someString in <code>main()</code>, right?</p>
<p><strong>case B</strong> <code>void MyClass::modifySomeString(const char*& inBuffer)</code></p>
<p>Here, I have a reference to the pointer so potentially I could actually modify the original "string" in main() (and probably should call the parameter inOutBuffer for clarity...). But besides the fact that I could cast to remove the const and modify the actual parameter inside my method... wouldn't this be just a bad thing to do? </p>
<p>I mean:</p>
<ol>
<li>someString was declared const in main to start with, so trying to pass it to a method for it to modify it is nonsensical</li>
<li>inside the method, if I'm stating the parameter is const too, again it just seems wrong to then try and go around its const to modify it affecting someString in main.</li>
</ol>
<p>Am I right about my observations on both cases A and B? Or is there a reason where it might be reasonable to pass a const string to a method and expect the method to still modify the original?</p>
<p>Personally, I think if I'm passing a const to the method, the method should instead have an out parameter where I get a new string without changing the original one. Something like:</p>
<pre><code>void MyClass::modifySomeString(const char* inBuffer, char*& outBuffer)
</code></pre>
<p>But I'm interested in suggestions or someone explaining why it's perfectly fine to modify the const parameter.</p>

javascript: determing the structure of an object programmatically
|
<p>I am building javascript (nodejs) integration with a remote service. The service returns inconsistently formatted results, and from within javascript, I am battling to determine how to switch my formatting based on the response.</p>
<p>The 2 formats are shown below, the first is when Parent has a single child, and the 2nd is where Parent has >1 children:</p>
<pre><code>var single = { "Parent" : { "name" : "foo" } }
var multi = { "Parent" : [ { "name" : "foo" }, { "name" : "bar" } ] }
</code></pre>
<p>So when I try and parse the results in js, accessing a child attribute of "name", I get inconsistent results:</p>
<pre><code>for (var i in single) {
console.log("child name: " + single[i].name;
}
for (var i in multi.Parent) {
console.log("child name: " + multi.Parent[i].name;
}
</code></pre>
<p>What would the best way be to determine whether I am getting a single or multi result back? I tried "typeof response", hoping to get an "Array" for multi, but that didn't work.The object is initially received as a string, but converted to an object using <code>JSON.parse(responseString)</code>.</p>

Multiple Variable Variables in PHP
|
<p>I am fairly new to PHP and programming in general... I am attempting to use a foreach loop to set some options on a page I have created. It all works except for the last section, where I am attempting to assign variables dynamically, so I can use them outside the loop.</p>
<pre><code><?PHP
$array=array(foo, bar, baz);
foreach ($array as $option) {
// I have if statements to determine what $option_req
// and $option_status end up being, they work correctly.
$option_req="Hello";
$option_status="World";
$rh='Req_';
$sh='Status_';
$$rh.$$option=$option_req;
$$sh.$$option=$option_status;
}
echo "<br>R_Foo: ".$Req_foo;
echo "<br>S_Foo: ".$Status_foo;
echo "<br>R_Bar: ".$Req_bar;
echo "<br>S_Bar: ".$Status_bar;
echo "<br>R_Baz: ".$Req_baz;
echo "<br>S_Baz: ".$Status_baz;
?>
</code></pre>
<p>When the loop is finished, should this now give me six variables? </p>
<pre><code>$Req_foo
$Status_foo
$Req_bar
$Status_bar
$Req_baz
$Status_baz
</code></pre>
<p>I have played with this a bit, searches on Google seem fruitless today.</p>

how to make visual studio javascript formatting work?
|
<p>For some reason Visual Studio javascript formatting does not understand the syntax:</p>
<pre><code>(function(){
})();
</code></pre>
<p>I'm getting "expected expression" in the second character of this line: <code>})();</code></p>
<p>So I was wondering if anyone had this problem before (want to format their code but visual studio stubbornly thinks the valid code has an error and refuses to do so) and how do we solve it?</p>

When should a Service be stopped
|
<p>My android application starts a service in the onCreate() callback of a class that extends Application. The service performs some background tasks that are relevant to the user only while the application is running. For that reason I would like to close the service when the application's last activity is closed. I've tried to perform closing the service in the callback onTerminate() , but it never gets called . So what would be the best place where a service should be closed ?</p>

Why is the destructor called when initializing a vector of objects?
|
<p>Something occurred in my program, and I can't find if it's supposed to happen or not. And if it is, I don't see why..</p>
<p>Here's the code :</p>
<pre><code>#include <iostream>
#include <vector>
using namespace std;
class A{
public:
A();
~A();
};
A::A(){
cout << "creating" << endl;
}
A::~A(){
cout << "deleting" << endl;
}
int main(void){
vector<vector<A > > vec;
vec.resize(5);
for(int i = 0; i < 5; ++i){
vec[i].resize(5);
}
cout << "END" << endl;
return 0;
}
</code></pre>
<p>And here's the output :</p>
<pre><code>creating
deleting
creating
deleting
creating
deleting
creating
deleting
creating
deleting
END
deleting
deleting
[..more deleting here]
</code></pre>
<p>I understand why the destructor is called after the "END" message, but before, I don't. I thought that when the vector resize, the constructor of the class is called, but why the destructor?</p>

Dropdown menu open on click close on click
|
<p>I have asked this question before but it was closed as I didnt ask it properly. My issue is that I have a wp photography site which is not live yet as I am customizing it..I am very new to jquery and css. It has a dropdown menu which when you click on an item eg Portfolio it will drop down a further sub menu which will then show galleries. Currently clicking on a main item with a sub menu will only drop it down or open it but if you click the same main item again it will not pull the sub menu back up or close it. As i have numerous galleries I would like to code it so that it pulls back up on a second click. The template was designed the way it is now but i would like change it to do this.</p>
<p>Please someone advice me and let me know what I need to provide.</p>

Selecting thumbnail and viewing full screen
|
<p>I have my app working where it comes to a screen with 6 thumbnails. The user will select one and the next screen is a full image. I've accomplished this through an OnClickListener to call a new activity/xml (I'm new at this, sorry if my terminology is a little off).</p>
<p>My question is: is there a way to avoid creating 6 activty/xml (one for each thumbnail)? ultimately, my app will have about 40 thumbnails that can be selected for full screen view. </p>
<p>I've been trying to follow examples online where it appears that the code is presenting the full image within java instead of referencing an xml file. I've also seen use of Bitmap and BitmapFactory. Is this the way to go?</p>
<p>If the full screen image can be created dynamically within java, will the Back button still work to the user back to the screen with 6 thumbnails?</p>
<p>thanks, J</p>

How to disable blinking of textview onClick

<p>I have a <code>TextView</code> with an <code>onClickListener()</code>.
When I click on the <code>TextView</code> it blinks.
How to disable this effect?</p>

android:id="@+id/descriptionText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/background"
android:ellipsize="end"
android:paddingTop="4dp"
android:paddingLeft="8dp"
android:maxLines="3"
/>
</code></pre>
<p>I tried to remove <code>android:ellipsize</code> and <code>android:maxLines</code> tags - no effect.</p>
<p>And here is the code:</p>
<pre><code>accountDescriptionTextView = (TextView) v.findViewById(R.id.descriptionText);
accountDescriptionTextView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (descriptionOpened)
{
// accountDescriptionTextView.setEllipsize(TextUtils.TruncateAt.END);
// accountDescriptionTextView.setMaxLines(3);
descriptionOpened = false;
}
else
{
// accountDescriptionTextView.setEllipsize(null);
// accountDescriptionTextView.setMaxLines(100);
descriptionOpened = true;
}
}
});
</code></pre>
<p>I need to have the commented functionality, but even when this lines are commented I still see how the textview blinks.</p>
<p>The text just disapears when i place my finger on the screen and apears when I take the finger away.</p>

How to Deep clone in javascript
|
<p>How do you deep clone a Javascript object?</p>
<p>I know there are various functions based on frameworks like <code>JSON.parse(JSON.stringify(o))</code> and <code>$.extend(true, {}, o)</code> but I don't want to use a framework like that.</p>
<p>What is the most elegant or efficient way to create a deep clone. </p>
<p>We do care about edge cases like cloning array's. Not breaking prototype chains, dealing with self reference.</p>
<p>We don't care about supporting copying of DOM objects and like because <code>.cloneNode</code> exists for that reason.</p>
<p>As I mainly want to use deep clones in <code>node.js</code> using ES5 features of the V8 engine is acceptable. </p>
<p>[Edit]</p>
<p>Before anyone suggests let me mention there is a distinct difference between creating a copy by prototypically inheriting from the object and <em>cloning</em> it. The former makes a mess of the prototype chain.</p>
<p>[Further Edit]</p>
<p>After reading your answer I came to the annoying discovery that cloning entire objects is a very dangerous and difficult game. Take for example the following closure based object</p>
<pre><code>var o = (function() {
var magic = 42;
var magicContainer = function() {
this.get = function() { return magic; };
this.set = function(i) { magic = i; };
}
return new magicContainer;
}());
var n = clone(o); // how to implement clone to support closures
</code></pre>
<p>Is there any way to write a clone function that clones the object, has the same state at time of cloning but cannot alter the state of <code>o</code> without writing a JS parser in JS.</p>
<p>There should be no real world need for such a function anymore. This is mere academic interest.</p>

Query the android Mediastore for Artist names of Music files

<p>I'm torn about how to implement this because Content Provider URI querys do not support the simple SQL "DISTINCT" query method to return a cursor to the Artists of the songs in the mediastore, removing any duplicate entries.</p>
<p>I can query and get a cursor to all the artists, I'm just torn as to how to remove the dupes, or simply not show them.</p>
<p>I've tried using matrixcursor to construct a new cursor with the dupe entries removed, but it's slow (build an array of artists, if in that array don't copy to the new matrixcursor, etc.)</p>
<p>Can anyone recommend a better solution, or point me in the proper direction??</p>
<p>I've also thought about pre-loading the information i need into an array of objects - I'm just concerned with memory overhead in my application.</p>

jQuery tabs with cookie support restore wrong tab position after page refresh
|
<p>I have tricky problem which I can't completely understand. It's jQuery tabs with cookie support. I've following code:</p>
<pre><code>$(document).ready(function() {
var $tabs = $("#tabs").tabs();
$tabs.tabs('select', $.cookie("tabNumber"));
$('#tabs ul li a').click(function() {
$.cookie("tabNumber", $tabs.tabs('option', 'selected'));
});
$('#btnSelect').click(function() {
//alert($.cookie("tabNumber"));
//$tabs.tabs('select', 2);
$tabs.tabs('select', $.cookie("tabNumber"));
});
});
</code></pre>
<p>So, I've 3 tabs (with positions 0,1,2) inside div named "tabs". When user selects one tab, then tab position stores in cookie. After that if user refresh page, active tab position must be restored.</p>
<p>But each time I refresh page I get active tab in previous position (if I select 2nd tab, then after refresh I got active tab in position 1, etc.).
I add some test in code (button btnSelect with onclick handler which duplicates load position functionality).
So, if I uncomment and use </p>
<pre><code>$tabs.tabs('select', 2);
</code></pre>
<p>Then after I click btnSelect I've got right position. Ok, that's right. Then I comment that line and uncomment next one:</p>
<pre><code>alert($.cookie("tabNumber"));
</code></pre>
<p>So, I select tab, click button, get dialog message "2", and after that tab in position 1 became active.
Why?? In both cases I call 'select' method with parameter 2...</p>
<p>I know I can use aliases for tabs, but I want to understate why my code doesn't work properly.</p>

<p>So far so good. Now I'm seeking to further secure the upload utility to prevent malicious scripts from being extracted from the uploaded zip files (the upload requires a zip file).</p>
<p>The downside to using a zip, I presume, is that it can contain any number or type of files that might make it more complicated to handle than otherwise.</p>
<p>So my question is for tips on how to further secure this uploader to make sure no malicious files are sent. The desired allowed files are .php, .jpg, .gif, .png</p>

remove duplication
|
<p>I have a class contains 10 methods which are doing almost the same things apart from one key event. Two examples are given below: </p>
<pre><code>
Public String ATypeOperation(String pin, String amount){
doSomething();
doMoreStuff();
requestBuilder.buildATypeRequest(pin, amount);
doAfterStuff();
}
</code>
<code>
Public String BTypeOperation(String name, String sex, String age){
doSomething();
doMoreStuff();
requestBuilder.buildBTypeRequest(name, sex, age);
doAfterStuff();
}
</code>
</pre>
<p>As you can see from the above methods, they are similar apart from calling different methods provided by requestBuilder. The rest 8 are similar too. There is a lot duplicated code here. I feel there is a better way to implement this, but don’t know how. Any ideas and suggestions are appreciated. </p>
<p>Thanks,
Sarah</p>

Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES
|
<p>At the risk of repeating what appears to be a very common complaint, I think I have a substantial variation on this bug.</p>
<p>The application won't install from Eclipse and this appears in the console: Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES.</p>
<p>LogCat provides some illumination: Package com.xxx has no certificates at entry assets/fonts/helvetica_neue.ttf; ignoring!</p>
<p>Meaning that the device (or emulator) believes that this particular file wasn't signed.</p>
<p>The usual solutions proposed for this are:<br/>
- Rename the offending file. We've tried that, it then complains about the next file, then the next, and so on.<br/>
- Add a dummy file. Tried that too. It complains about the new file, regardless of what it's called.<br/>
- Compile for greater than Android 1.6. We're compiling for 2.3.</p>
<p>It's worth noting this only happens when we launch a unit test. We can install the "real" application on its own with no difficulties. We're also using Maven and, of course, the Maven Android plugin.</p>
<p>Any insights or suggestions would be very welcome and of course if we figure it out on our own I'll post any findings.</p>
