php script to generate checksum from md5
|
<p>In order to calculate the checksum i need following things. these parameters are concatenated in a constant (no spaces) string made up of the values of the following parameters in the exact order listed below:
o Secret Key
o Merchant id
o Currency
o Total amount
o Item list (item_name_1, Item_amount_1, item_quantity_1 to item_name_N,
Item_amount_N, item_quantity_N)
o Timestamp</p>
<p>e.g
In that case the string befor hash will be:
pLAZdfhdfdNh57583USD69.99Tier2 item69.9912010-06-14.14:34:33</p>
<p>And using the MD5 hash function the result is:
ghvsaf764t3w784tbjkegbjhdbgf</p>
<p>i want to know how can i create a php script that will call md5 hash function with the inputs given above and based on that it will generate the hash function value that will be the checksum value for my coding..</p>

Reference on interface as a parameter
|
<blockquote>
<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/114180/pointer-vs-reference">Pointer vs. Reference</a> </p>
</blockquote>
<p>I am wondering if there any benefits in using references instead of pointers on some interface. Being more specific let's consider small example:</p>
<pre><code>struct MyInterface {
virtual ~MyInterface() {}
virtual void f() = 0;
};
class MyClass : public MyInterface
{
virtual void f()
{
std::cout << "F()" << std::endl;
}
};
void myFunction(MyInterface& obj);
int main(int argc, char *argv[])
{
MyInterface* pObj = new MyClass;
myFunction(*pObj);
delete pObj;
getchar();
return 0;
}
void myFunction(MyInterface& obj)
{
obj.f();
}
</code></pre>
<p>In <em>myFunction</em> instance of <em>MyClass</em> can be passed as a pointer, what is written in many books. My question is what can be considered as a good practice (pointer or reference) and what is more efficient?</p>
<p>Sorry if this question somehow was asked previously. </p>

How to put PHP class definition in include file
|
<p>I'm new to PHP, having trouble when I move a class definition out of my "main" page and into an include file.</p>
<p>Suppose I have main.php, with the below contents. It works fine:</p>
<pre><code><?php
class SimpleClass
{
public $var = 'a def value';
public function displayVar() {
echo $this->var;
}
}
?>
<html>
<h1>blah blah blah</h1>
</html>
</code></pre>
<p>But now suppose that I try removing the class definition and putting it in a <strong>separate</strong> file, so that the main.htm now looks like:</p>
<pre><code><?php
include("classdef.php");
?>
<html>
<h1>blah blah blah</h1>
</html>
</code></pre>
<p>and classdef.php is:</p>
<pre><code><?php
class SimpleClass
{
public $var = 'a def value';
public function displayVar() {
echo $this->var;
}
?>
</code></pre>
<p>Then when I view my main.php, it displays as</p>
<pre><code>var; } } ?>
blah blah blah
</code></pre>
<p>As if the <code>></code> character in the <code>$this->var</code> is interpreted as closing the PHP. I've had trouble searching for this, in that I don't know what the <code>-></code> operator is called.</p>
<p>This is PHP 5.3.3 on Apache 2.2 on Windows.</p>

Effectively caching data uploads in Android
|
<p>I have implemented a queue service in Android that will change states based on queue and wifi/data connectivity events.</p>
<p>I queue transactions to be posted to a remote url. If the device has a data or wifi connection, it will iterate the queue and post data to the url until the queue is empty, or there is a disconnect event.</p>
<p>I can login to my app, enable airplane mode, generate data, turn airplane mode off, and the transaction are posted. No slow down, even with thousands of transactions. (I was trying to pish it a bit)</p>
<p>Enter: low reception!
My app slows down enormously when the 3G reception is low. (Yes, all uploading happens off the ui thread.) It seems that the cause of this slow down has to do with the post to the server taking a very long time to happen and sometimes just failing.</p>
<p>My question is, how can I solve this? Check for signal quality? Poll a known address? How do other apps, such as Gmail solve this? This must be a common scenario!</p>

Working with interfaces
|
<p>I have functions of the following form in the code I'm refactoring:</p>
<pre><code>A f()
{
if(existing)
return A();
else
return A(handle);
}
</code></pre>
<p>The Safe Bool Idiom is later used to test if A is associated with a handle or not, i.e. if we should call the class methods for this object which require internally a valid handle for execution. A's methods are const.</p>
<p>I'd like to return an interface, IA, here instead. Must I therefore return a pointer? If so I will go with boost shared pointers. I can test if the pointer is pointing to something or not.</p>
<p>Is there any way for me to work with references here instead? Would you recommend such an approach or do you think that boost::shared_ptrs is the way to go?</p>
<p><strong>UPDATE</strong></p>
<p>A is derived from IA.</p>
<p>My compiler is gcc version 4.4.3.</p>
<p>My biggest problem with this code is that A is used to interact with an external C API. Therefore I wish to mock it away using the IA interface as base for my Mock of A and its implementation, A. Then outside of the method f() above, which I see as a factory, I will only work with IA pointers. Dependency Injection in other words.</p>
<p>So A is basically a handle and an interface to a set of C API functions which require a handle. I can have several objects of type A where the interface is the same but the handle is different. </p>

Can a selector resource use a color defined in a style?
|
<p>I'm trying to use a color defined in a stlyle in a selector but it is causing a Resources$NotFoundException.</p>
<p>First I added a new attribute to attr.xml:</p>
<pre><code><resources>
<attr name="unread_background" format="color" />
</resources>
</code></pre>
<p>Then I defined that attr value in styles.xml:</p>
<pre><code><style name="ThemeNoTitleBar" parent="android:Theme.NoTitleBar">
<item name="unread_background">#000000</item>
</style>
</code></pre>
<p>Then I tried to use that attr in my selector definition:</p>
<pre><code><selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- other states snipped -->
<item android:state_selected="false"
android:drawable="?unread_background" />
</selector>
</code></pre>
<p>Lastly, the activity uses the ThemeNoTitleBar style theme in the manifest.</p>
<p>I've also tried creating a color in colors.xml and having it use the new attr but that also fails.</p>
<p>I'm obviously missing something but am not sure what to do to fix it. My intent is to create multiple themes and have the selector use the color in the currently selected theme.</p>

Any difference in " 'value' == typeof X " VS " typeof X == 'value' "
|
<p>Is there any difference (compiler/interpreter/juju wise, etc) between the two versions of checking the result of the typeof operator?</p>
<p>I am asking because I see the first version a lot of times, as if it followed a concept, while version two is way more readable and better describes my intention: primarily I am interested in the type of a variable and not a string being equal with something. </p>
<p>UPDATE:
while it's not part of the original question it worth noting that x == y is never a good practice when you are about to check equality. One should always use the === operator for that.</p>

Status of chained assignment in Python
|
<p>At several occasions I stumbled upon C-style assignment in Python such as <code>a = b = 0</code>. By diligent Googling I found out that this is called chained assignment: [<a href="http://en.wikipedia.org/wiki/Assignment_%28computer_science%29#Chained_assignment" rel="nofollow">1</a>],[<a href="http://stackoverflow.com/questions/11498441/what-is-this-kind-of-assignment-in-python-called-a-b-true">2</a>],[<a href="http://stackoverflow.com/questions/7601823/how-do-chained-assignments-work">3</a>]. However, it appears that this feature is not mentioned in the <a href="http://docs.python.org/3/reference/simple_stmts.html#assignment-statements" rel="nofollow">official documentation</a>.</p>
<p>Does this mean that chained assignment is still in experimental phase, or simply that the official documentation is slightly behind the development?</p>

How to refresh activity after changing language (Locale) inside application
|
<p>My application users can change the language from the app's settings. Is it possible to change the language inside the application without having effect to general language settings ?
<a href="http://stackoverflow.com/questions/2264874/android-changing-locale-within-the-app-itself">This question of stackoverflow</a> is very useful to me and i have tried it. After changing language newly created activities display with changed new language, but current activity and previously created activities which are in pause state are not updated.How to update activities ?
I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed. When application is restarted, all activities created again, so now language changed correctly.</p>
<pre><code> android:configChanges="locale"
</code></pre>
<p>also added in manifest for all activities. and also support all screen.
Currently I have not done any thing in activity's onResume() method.
Is there any way to refresh or update activity (without finish and starting again) ? Am I missing something to do in onResume() method? </p>

<p>I am trying to make a link unclickable once it is clicked, then clickable once another link is clicked. Basically just a toggle but I need to make the active link unclickable to prevent the toggle. Here is my code:</p>
<pre><code>$(document).ready(function(){
$("#Espanol").hide();
$("#espLink").addClass("nonSelected");
// Make english link unclickable
$("#espLink").click(function(){
$("#engLink").addClass("nonSelected");
$("#espLink").removeClass("nonSelected");
$("#English").toggle();
$("#Espanol").toggle();
// need to make espanol link unclickable
// and english link clickable
});
$("#engLink").click(function(){
$("#espLink").addClass("nonSelected");
$("#engLink").removeClass("nonSelected");
$("#English").toggle();
$("#Espanol").toggle();
// need to make english link unclickable
// and espanol link clickable
});
});
</code></pre>
<p>And html:</p>
<pre><code><a id="engLink">English</a> | <a id="espLink">Español</a>
</code></pre>
<p>Anybody know how to do this?</p>

Value selected option dropdownbox
|
<p>I've got a dynamic dropdownbox:</p>
<pre><code>function chgAantal(i,artNr,lengte){
var aantal=document.getElementById("aantal_"+i).value;
if(isNaN(aantal)){
alert('Voer een geldig aantal in...');
document.all["error_"+i].src="/images/fout.gif";
ok=0;
}
else{
location.href="addcart.asp?act=change&aantal="+aantal+"&artNr="+artNr+"&lengte="+lengte+"&bdr=<%=bdr%>";
}
}
<select onchange='chgAantal(\""+i+"\",\""+artNr+"\",\""+lengte+"\")' name='aantal_"+i+"' value='"+aantal+"'/>
<option value='1'>1</option>
<option value='2'>2</option>
<option value='3'>3</option>
<option value='4'>4</option>
<option value='5'>5</option>
<option value='6'>6</option>
<option value='7'>7</option>
<option value='8'>8</option>
<option value='9'>9</option>
</select>
</code></pre>
<p>When I change the value in (for example) 7, the value changes in the script. But I can't see the selected value, the value displaying is always 1.
How can I display the selected value?</p>
<p>I hope you understand me!</p>

Disabling onclick() after 1 click
|
<p>I am having a little trouble with a JS event. I have an link that calls the onclick event which opens up a photo in a popup modal window - facebox.</p>
<p>When the user single clicks on the link the image file name attached to that link is passed to the modal window, however if the user double clicks the image file opens twice in the modal window.</p>
<p>I have tried a simple ondblclick="" and ondblclick="return false" to stop this but it seems the browser still interprets it as 2 single onclick() events.</p>
<p>Can anyone suggest a fix or a solution whereby the link is temporarily disabled after the 1st click?</p>
<p>Here is the code below that is calling the event:</p>
<pre><code><a href="javascript:void(0);" onmouseover="setVisibility(\'deletephotodiv'.$do.'\', \'block\');" onmouseout="setVisibility(\'deletephotodiv'.$do.'\', \'none\');" ondblclick="parent.jQuery.facebox({ ajax: \'profile/previewphoto.inc.php?photo=',$_SESSION['images'][$do]['name'],'&album=',$_SESSION['images'][$do]['albumname'],'\' }); ">

Python: How to define a function that gets a list of strings OR a string
|
<p>Let's say I want to add a list of strings or just one to a DB:</p>
<pre><code>names = ['Alice', 'Bob', 'Zoe']
</code></pre>
<p>and I want that <code>add_to_db</code> will accept both cases</p>
<pre><code>add_to_db(names)
add_to_db('John')
</code></pre>
<p>Is this the correct way to go:</p>
<pre><code>def add_to_db(name_or_names):
if (...):
... # add a single name
else:
for name in name_or_names:
... # add a single name
commit_to_db()
</code></pre>
<p>What should I put in the first <code>...</code>, as condition to whether it's a list of strings or just a string (don't forget that string is also iterable)?</p>

Android: How to use fragments to completely change a view
|
<p>My app has a custom segmented control(got it from internet - its really a radio group) and under it a listview. When a user clicks on a row in the list view, a fragment is attached to the activity that displays a different listview. This new listview seems to replace the old one. The problem is that the segmented control is still there, whereas I would like the whole view to be the new list view. Knowing that fragments are embedded in the view group, I thought progammatically removing the segmented control would work, but it didn't, the control just becomes empty space. </p>
<p>It's important that the app works the way I described. I could explain in detail why this is so, if needed.</p>
<p>Any tips? Much appreciated.</p>

Working very slow
|
<p>My application connects to web server, downloads data (approximately 43000 Bytes) and do mathematics function (such as log, +, -, * etc...) on each byte. </p>
<p>To prepare apk file, it is just like publishing to android market. Turned off debug mode and deactivated all loggers.</p>
<p>Then put it to the web server and downloaded (installed) on my HTC device. After installation, I've tested the application.
The time from beginning read bytes to end of task is approximately 4 minutes. It is very slow.</p>
<p>I've researched this part. It seems that is working slow on mathematics functions. </p>
<p>Is there any way to increase working speed ? </p>
<p>My code is same as iphone version of my application. It is very fast. All parts complete in 4 - 10 seconds. </p>
<p>What is wrong here ?</p>
<p>Or do I need to any configuration (related debug mode) ?</p>
<p>Please advice.</p>

Two-Way Ajax Binding
|
<p>Alright, here goes... I'm learning JavaScript, so I thought it would be a cool coding exercise to have two-way ajax binding between elements. Except I'm stuck. What do I mean by two-way ajax binding (I made up the term, I hope it's an accurate description of what I'm going for)? Well, say I had a simple box, created in the markup with a div, styled 200px by 200px, red. It wouldn't take any effort at all to make two textareas where, by typing in 500 in the first, and 100 in the second, the size of my div/box would go from 200px in height to 500px in height, and the width of my box would go to 100px in width. But what if I wanted to make it the other way around, simultaneously? Is that possible? Could, on the same page, you be able to type something in a textarea and make the div resize automatically, but at the same time, you be able to select the corner of the div and resize it, updating the textarea in real time via Ajax? How would that be implemented? Once I learn Vanilla JavaScript, I'm planning on learning jQuery, so another thing I was wondering is: is that sort of thing implementable in jQuery?</p>
<p>Thanks! Sorry if that seemed incomprehensible :/</p>
<p>I'm sorry, I'm new to JavaScript, I tried this as an exercise, but now I'm stuck. Apologies...</p>

<p>My problem is, typically 1 of the 200 emails will never arrive. I don't see any error messages on the console, so I'm assuming that the email was send to the SMTP server, and the SMTP server is dropping the ball.</p>
<p>But before I bug the SMTP guys, I want to make sure I'm not missing an error somewhere.</p>
<p>Is there somewhere other than the console where python will output the error message?</p>
<p>Thanks,
Rob</p>

JavaScript object data and Arrays
|
<p>I have a JavaScript object as follows.</p>
<pre><code>var sampleData = {
"studentsList": {
"Student1": {
"marks": "123",
"grade": "B"
},
"Student2": {
"marks": "144",
"grade": "A"
}
}
};
</code></pre>
<p>Now the user enters the name of a student, say <code>Student1</code> and I need to get the details of that object. </p>
<p><strong>I have two questions.</strong></p>
<p><strong>[1]</strong> How do I get the details of the entered student using JavaScript? </p>
<p>When I use <code>sampleData.studendsList.valueOf("Student1")</code> returns me the complete object. I just need the details of "Student1".</p>
<p><strong>[2]</strong> Is this the correct way to do it? Or we should create an array of Students and that contains an property called "name" with value say <code>Student1</code> ? If I go with this approach then I need to iterate through the entire array list to get the details of a student. </p>
<p>Which appraoch is better?</p>

howto create a new Date() in Javascript from a non-standard date format
|
<p>i have a date in this format : dd.mm.yyyy</p>
<p>when i instantiate a javascript date with it, it gives me a NaN</p>
<p>in c# i can specify a dateformat, to say: here you have my string, it's in this format, please make a Datetime of it.</p>
<p>is this possible in javascript too, and if not, is there an easy way?</p>
<p>i would prefer not to use a substring for day, substring for month etc. because my method must also be capable of german, italian, english etc dates.</p>

how to compare two files and extract the difference?
|
<p>I created a video recorder which stores recording to a file. I would like to implement a method which would read the file each second, compare the current file with the old value (1 second older) and write the difference to a separate file.</p>
<p>I would be very thankful if anyone could explain how to do that or write a simple example. I guess there has to be a thread which compares the new value with the old one by calling a custom method compareFiles(File currentFile, File oldFile) on a given period of time. The old file could also be saved as a temporary file and the current file at the original path could be compared with temporary file.</p>
<p>Any suggestion about the improvement of the described logic is more than welcome!</p>

c# dynamically pass string method at run time for string manipulation
|
<p>How do I dynamically pass string methods to be applied to strings at run time.
ex.</p>
<pre><code>Private String Formatting(String Data, String Format)
</code></pre>
<p>When we pass <code>String S1 = "S1111tring Manipulation"</code> and <code>format = Remove(1,4)</code> - behind the scenes it becomes <code>S1.Remove(1,4)</code> resulting in "String Manipulation"</p>
<p>or if we pass <code>String S1 = "S1111tring Manipulation"</code> and <code>format = ToLower()</code> behind the scene it becomes <code>S1.ToLower()</code> resulting in <code>"s1111tring manipulation"</code></p>
<p>I should be able to pass any valid method like <code>PadLeft(25,'0')</code>, <code>PadRight</code>, <code>Replace</code> etc...</p>
<p>I would appreciate a complete example</p>
<p>This is what I have tried and it does not work</p>
<pre><code>using System.Reflection;
string MainString = "S1111tring Manipulation";
string strFormat = "Remove(1, 4)";
string result = DoFormat(MainString, strFormat);
private string DoFormat(string data, string format)
{
MethodInfo mi = typeof(string).GetMethod(format, new Type[0]);
if (null == mi)
throw new Exception(String.Format("Could not find method with name '{0}'", format));
return mi.Invoke(data, null).ToString();
}
</code></pre>
<p>throws an error (Could not find method with name 'Remove(1, 4)') - so I am not sure how to proceed</p>

Calling a new Form from a separate thread and avoid frozing the form

<p>I am currently creating a chat system. The receiving end of the client side is managed by a separate thread so that when it receives a message from another client, a new Form is loaded bearing the message of the sender. The problem is, the newly loaded form is frozen and is not responding [due to the blocked methods I use (?)]. How can I solve that problem? I am new to C# so please put in the code snippet.</p>

Scrolling a div of images

<p>I'm looking for a simple way to scroll a list of images horizontally across a div, and have the pattern repeat (an infinite loop of images moving slowly from left to right). </p>
<p>Currently using <a href="http://logicbox.net/jquery/simplyscroll/" rel="nofollow">http://logicbox.net/jquery/simplyscroll/</a> for this task, but it has a lot of features I don't need (such as user controls and vertical scrolling). My hope is that there's a simple way to code this in jQuery in a few dozen lines.</p>
<p>I'm confident I can build something to scroll the images horizontally, but getting them to loop is beyond me. </p>
<p>Any help, information, or even a new script (that has been updated recently) would be awesome. Thanks!</p>
