Returning a reference can work?
|
<p>I used to think returning a reference is bad as our returned reference will refer to some garbage value. But this code works (<code>matrix</code> is a class):</p>
<pre><code>const int max_matrix_temp = 7;
matrix&get_matrix_temp()
{
static int nbuf = 0;
static matrix buf[max_matrix_temp];
if(nbuf == max_matrix_temp)
nbuf = 0;
return buf[nbuf++];
}
matrix& operator+(const matrix&arg1, const matrix&arg2)
{
matrix& res = get_matrix_temp();
//...
return res;
}
</code></pre>
<p>What is <code>buf</code> doing here and how does it save us from having garbage values?</p>

Installing different versions of the same iPhone project?
|
<p>While I'm prototyping games, I frequently need to go back to compare with older versions, to better get a feel of if I'm on the right track or not. But it's a lenghty process to have to check out the old version and re-export everytime I need to check a specific version. It'd be so much smoother if I could simply launch different versions.</p>
<p>How can I have multiple versions of the same project installed on the device?</p>

textview not updating as expected
|
<p>I have multiple <code>TextView</code> and <code>EditText</code> fields in two different activities. When I go to my Edit screen, I can input values and the corresponding <code>TextViews</code> are updated. The problem is that if I were to edit just one <code>TextView</code>, then the other <code>TextViews</code> go blank and only the ones I edited will show the correct info. Any suggestions? Attached is a snippet of code. So basically, I only want the <code>TextView</code> info to change when the <code>EditText</code> field is changed and not when the <code>EditText</code> is just selected or scrolled through.</p>
<p>The <code>EditText</code> code:</p>
<pre class="lang-java prettyprint-override"><code>editTextName.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v1, int keyCode1, KeyEvent event1) {
if ((event1.getAction() == KeyEvent.ACTION_DOWN) && (keyCode1 == KeyEvent.KEYCODE_ENTER)) {
getSharedPreferences("myprefs", 0).edit().putString("editTextName", editTextName.getText().toString()).commit();
return true;
}
return false;
}
});
</code></pre>
<p>The corresponding <code>TextView</code>:</p>
<pre class="lang-java prettyprint-override"><code>String newName = getSharedPreferences("myprefs", 0).getString("editTextName", this.getString(R.string.name) );
textViewName.setText("Name: "+newName);
</code></pre>

lock-less technique to pass double update from one thread to another
|
<p>Assume I have shared <code>double</code> variable. Thread <code>A</code> updates it several thousands times per second. In another thread <code>B</code> I want to be notified somehow about "update" every time this happens.</p>
<p>I was tried to avoid notifications completely and just use <code>while(true)</code> loop but this introduced significant slowdowns into my program <a href="http://stackoverflow.com/questions/11392169/lock-free-calc-how-to-sum-n-double-numbers-that-are-changing-by-other-threads">lock-free calc: how to sum N double numbers that are changing by other threads?</a> probably because of that "Meanwhile you keep on loading that same array from memory over and over which is not really good for performance since memory bandwith is limited."</p>
<p>I've also tried using <code>Monitor</code> class but it was also pretty slow and I've seen up to 1-2 ms delays when <code>Monitor.TryEnter</code> return <code>false</code>.</p>
<p>I now think that I need to do notifications using lock-free technique, probably using <code>SpinLock</code> or something else?</p>

explicit filepath to file in parent directory

<p>I have a situation where I have two config files.<br>
A base config which resides in a parent directory, and a sibling config in a sibling directory.<br>
To date, the sibling looks to the parent with a simple </p>
<pre><code>require_once "../parent_config.php";
</code></pre>
<p>However I now want to pass the sibling into a new class system. I can pass an explicit filepath for the sibling no problem, but obviously run into issues with the above call to the parent.<br>
I'm trying something along the line of the following but I'm getting it wrong somewhere (I'm trying to say take the explicit filepath, up one)</p>

Now it is redirecting to different page for each company using passing parameter (ex. company.aspx?ID=10) and everytime when I clicked, it refreshes whole page. I would like to keep side menu user control without refresh as there is a live search option. </p>
<p>Is this possible? or should I change opposite way to do it? should be the side menu in a page and company info in a user control??</p>

"Select StudentID, RollNo, AdmissionID,(FirstName + Space(1) + Isnull(MiddleName,'') + Space(1) + Isnull(LastName,'')) as Name," +
" PermState as State from Students where ClassId = '" + ddlClass.SelectedValue + "'" +
" order by RollNo";
DataTable dt = bl.GetDataSet(sql);

How to animate a set of jQuery objects one at a time (instead of all at once)
|
<p>I'm trying to build a picture slider. (I know there are tons of plug-ins out there, but this is more for educational purposes).</p>
<p>Basically, I have a set of images with z-index: 0. What I am trying to do is take the set of images, then select each one of the images and change the index to 1, animate the opacity, and then put it back at 0, so that the next image will do the same thing.</p>
<p>This is the first part, but the problem I have is that when I am testing this part, all the images do the animation at the same time. Instead of doing one after the other.
I know that you can use callback functions such as:</p>
<pre><code>image1.animate(the animation, function({
image2.animation(the animation, function({
image3.animation(the animation, function}) etc...
</code></pre>
<p>})</p>
<p>But if I had more images it would become more complicated. I am trying to find a more efficient way of doing this, but I am not finding the answer.</p>
<p>This is what I have tried:</p>
<pre><code>images.each(function () {
$(this).css({
"opacity" : "0.0",
"z-index" : "1"
}).animate({
opacity: "1.0"
}, 3000);
});
</code></pre>
<p>but it doesn't work. All the images do the animation at the same time. I even tried with a "for" loop, but I get the same thing:</p>
<pre><code>for (var i=0; i<images.length; i++){
images.eq(i).css({
"opacity" : "0.0",
"z-index" : "1"
}).animate({
opacity: "1.0"
}, 3000);
}
</code></pre>
<p>I know I am doing something wrong, but I can't figure out what it is. If anyone has any help it would be greatly appreciated!</p>

jquery "everyTime" function

Set StringBuilder before use?
|
<p>Does a StringBuilder variable need to be initialized to lets say string.empty in case you don't end up appending anything in the end and need to return something?</p>
<pre><code> public static string ToSemiColonList<T>(this IEnumerable<T> list, Func<T, string> func)
{
StringBuilder sb = new StringBuilder();
foreach (T item in list)
{
if (sb.Length > 0)
sb.Append(";");
string elem = func(item);
sb.Append(elem);
}
return sb.ToString();
}
</code></pre>
<p>In this case it may never enter the foreach. So my guess is since every local variable in a method scope is set to no value in C#, to set it to an empty string since we need to give something back if this foreach is not hit.</p>
<p>Maybe it's better to check the stringbuilder length then if zero, return string.empty or am I going overboard (doing the same work twice) and it's fine like I have it?</p>

Joining Lists using Linq returns different result than corresponding SQL query?
|
<p>I have 2 tables</p>
<p>TableA:</p>
<pre class="lang-none prettyprint-override"><code>TableAID int,
Col1 varchar(8)
</code></pre>
<p>TableB:</p>
<pre class="lang-none prettyprint-override"><code>TableBID int
Col1 char(8),
Col2 varchar(40)
</code></pre>
<p>When I run a SQL query on the 2 tables it returns the following number of rows</p>
<pre class="lang-sql prettyprint-override"><code>SELECT * FROM tableA (7200 rows)
select * FROM tableB (28030 rows)
</code></pre>
<p>When joined on col1 and selects the data it returns the following number of rows</p>
<pre><code>select DISTINCT a.Col1,b.Col2 FROM tableA a
join tableB b on a.Col1=b.Col1 (6578 rows)
</code></pre>
<p>The above 2 tables on different databases so I created 2 EF models and retried the data separately and tried to join them in the code using linq with the following funtion. Surprisingly it returns 2886 records instead of 6578 records. Am I doing something wrong?
The individual lists seems to return the correct data but when I join them SQL query and linq query differs in the number of records.</p>
<p>Any help on this greatly appreciated.</p>
<pre><code>// This function is returning 2886 records
public List<tableC_POCO_Object> Get_TableC()
{
IEnumerable<tableC_POCO_Object> result = null;
List<TableA> tableA_POCO_Object = Get_TableA(); // Returns 7200 records
List<TableB> tableB_POCO_Object = Get_TableB(); // Returns 28030 records
result = from tbla in tableA_POCO_Object
join tblb in tableB_POCO_Object on tbla.Col1 equals tblb.Col1
select new tableC_POCO_Object
{
Col1 = tblb.Col1,
Col2 = tbla.Col2
};
return result.Distinct().ToList();

<p>Then in another assembly this:</p>

private static void DoSomethingElse(int orderID)
{
List<order> orderList = ClassA.GetOrders(orderID);
...rest of code

Origin null is not allowed by Access-Control-Allow-Origin (Synchronous, no jQuery)
|
<p>The first thing I would like to say is that I looked around for an answer to this for quite some time, but everything I found was about jQuery. This is not about jQuery. </p>
<p>I have some code (below), but when I ran it in Firefox then Firebug gave me this big, incomprehensible exception. I tried it in Google Chrome and got something a bit more useful: "XMLHttpRequest cannot load <a href="http://www.wikipedia.org/" rel="nofollow">http://www.wikipedia.org/</a>. Origin null is not allowed by Access-Control-Allow-Origin." (If you'd like to know why I was trying to access Wikipedia, I often use it as a test site.)
Here is my code:</p>
<pre><code>function requestSite(url) {
var xmlhttp;
if (window.XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
}
else {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET", url, false);
xmlhttp.send();
return xmlhttp;
}
</code></pre>
<p>All I tried to do with it was access Wikipedia. Then Google, which gave me the same result. Perhaps it is worth noting that when I triggered the function with a button on the page, it gave me this, while using the console was exactly the same, but without the error message. Another thing that may or may not be worth mentioning is that I was running this file from my local filesystem.</p>

Python class structure ... prep() method?

<p>We have a metaclass, a class, and a child class for an alert system:</p>

"""
Metaclass for all alerts
Reads attrs and organizes AlertMessageType data
"""
def __new__(cls, base, name, attrs):
new_class = super(AlertMeta, cls).__new__(cls, base, name, attrs)
# do stuff to new_class
return new_class
class BaseAlert(object):
"""
BaseAlert objects should be instantiated
in order to create new AlertItems.
Alert objects have classmethods for dequeue (to batch AlertItems)
and register (for associated a user to an AlertType and AlertMessageType)
If the __init__ function recieves 'dequeue=True' as a kwarg, then all other
arguments will be ignored and the Alert will check for messages to send
"""
__metaclass__ = AlertMeta
def __init__(self, **kwargs):
dequeue = kwargs.pop('dequeue',None)
if kwargs:
raise ValueError('Unexpected keyword arguments: %s' % kwargs)

self.dequeue()

"""
# Dequeue from a custom queue
class CustomAlert(BaseAlert):
def __init__(self,**kwargs):
# prepare custom init data
super(BaseAlert, self).__init__(**kwargs)
</code></pre>
<p>We would like to be able to make child classes of BaseAlert (CustomAlert) that allow us to run dequeue and to be able to run their own <code>__init__</code> code. We think there are three ways to do this:</p>
<ol>
<li>Add a prep() method that returns True in the BaseAlert and is called by <code>__init__</code>. Child classes could define their own prep() methods.</li>
<li>Make dequeue() a class method - however, alot of what dequeue() does requires non-class methods - so we'd have to make those class methods as well.</li>
<li>Create a new class for dealing with the queue. Would this class extend BaseAlert?</li>
</ol>
<p>Is there a standard way of handling this type of situation?</p>

Accessing theme customizer farbtastic object instances

<p>I am trying to find the jQuery/JavaScript instance variable for each of these, just can't seem to find a reference to them anywhere. I want to be able to set each farbtastic color manually, i.e. I need to access the color pickers setColor() method.</p>
<p>As a test, I can set a global JS var in customize-controls.js, in the color picker section, and can access this via Chrome console easy enough. But I need to do the same thing by accessing the default farbtastic instances. I just can't find them!</p>

Console information to window
|
<p>I already know how to catch standard output of a console window, BUT my problem is the case when I get the process with GetProcesses/orByName and do not Start() it myself. Here is the code:</p>
<pre><code>public ProcessCaller(ISynchronizeInvoke isi, Process MárFutóAlkalmazás)
: this(isi)
{
//alapbeállítások
FileName = MárFutóAlkalmazás.StartInfo.FileName;
Arguments = MárFutóAlkalmazás.StartInfo.Arguments;
WorkingDirectory = MárFutóAlkalmazás.StartInfo.WorkingDirectory;
//egyedi beállítások
process = MárFutóAlkalmazás;
process.EnableRaisingEvents = true;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
new MethodInvoker(ReadStdOut).BeginInvoke(null, null);
new MethodInvoker(ReadStdErr).BeginInvoke(null, null);
//események
StdErrReceived += new DataReceivedHandler(Loggolás);
StdOutReceived += new DataReceivedHandler(Loggolás);
//kilépés jelzése
process.Exited += new EventHandler(OnKilépés);
}
</code></pre>
<p>So this method gets and already running application as MárFutóAlkalmazás parameter. Sets some internal properties, then hooks to Output. However when it comes to</p>
<pre><code>StdOutReceived += new DataReceivedHandler(Loggolás);
</code></pre>
<p>and the program runs the Loggolás method to take the console data, it says that the StandardOut is not set, or the process is not started.</p>
<p>Well:</p>
<ul>
<li>StandardOut is set</li>
<li>Process is running, since I get it by GetProcesses</li>
<li>In this routine I do NOT use process.Start() - since it is started already</li>
</ul>
<p>Looking for help. Thank yas:
Péter</p>

Traversing directories to count number of files with a specific string
|
<p>I have a directory with several levels of sub-directories. All the files in the directories are html files (approx. 500 in total), and I'd like to go through each file to see if if contains a "sub_middle_1col" division. I found a great tutorial at palewire.com and have used that as my base. The two difficulties I am having are 1) the code broke when it hit a sub-directory (thinking it was a file), and 2) it would not traverse sub-directories -- that is, it only looks at files not in any sub-directory. I may have solved the first problem by adding in a line (noted below), but can't figure out how to integrate other solutions I've seen (e.g., os.walk) into the code in order to solve the second problem. Any ideas? Thanks in advance for any advice.</p>
<pre><code>import os
path = "./Industries"
my_library = os.listdir(path)
out = open("out.txt", "w")
for page in my_library:
file = os.path.join(path, page)
if os.path.isfile(file) and file.endswith('.html'): #I ADDED THIS LINE
text = open(file, "r")
hit_count = 0
for line in text:
if 'sub_middle_1col' in line:
hit_count = hit_count + 1
print >> out, page + " => " + str(hit_count)
print page + " => " + str(hit_count)
text.close()

How to make script paths inside user control independent of page hierarchy
|
<p>My website is organized in the following folder structure</p>
<pre><code>Root
Pages
CustomerManagement
DepartMentManagement
Script
UserControls
</code></pre>
<p>Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way</p>
<pre><code><script type="text/javascript" language="javascript" src="../Script/slider.js"></script>
</code></pre>
<p>My understanding is that since both are under root so i have used a single ..
Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work.</p>
<p>I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.Please tell me how to achieve this.</p>

getting an index of a character
|
<p>I'm having a problem getting an index of the character '-' of a string. Let me explain my problem.
First I have to read a line from a text file. The only line in the text file is "Beta = 62.5 * (Sigma – Delta) / 125"</p>
<pre><code>StreamReader rdr = new StreamReader(openPath, Encoding.Default);
while (rdr.Peek() != -1)
{
string strInput = rdr.ReadLine();
}
</code></pre>
<p>then I need to get the index of char '-'.</p>
<pre><code>int col = strInput.IndexOf('-');
</code></pre>
<p>After the above line 'col' is equal to -1. But as you can see the '-' character is in the above mentioned string which read from the text file.
I couldn't figure out why I'm getting -1 as the index of '-'. help me...</p>

parse rss feed using javascript

My issue with with the JavaScript. I am able to get the entire JavaScript document if I use <code>console.log(rssData);</code> with no errors.

The steps to becoming an iPhone Developer
|
<p>First some background:</p>
<p>The company I work for have decided to create an iPhone App for our main product and nominated me to do this work. I've been a professional C# developer for over 5 years and although I have used other languages (Java, C++ etc), I have not used them to a professional standard and not for many years. As for Mac/iPhone development I have never even used a Mac and have an Android phone.</p>
<p>My company are happy for me to go on any needed courses, buy any required books etc, to speed up the learning curve.</p>
<p>My first task is researching what I need (equipment, IDE's, SDKs) and what learning material to use (books, forums, courses - we're London based but if the course is good enough they might put me on a plane).</p>
<p>Of course I will be trawling the internet for some of these answers but I thought I can't hurt to consult the considerable knowledge of stack overflow (kissing ass I know!). Plus I'm sure there will be many people like me who could do with pointing in the right direction.</p>
<p>Thanks in advance.</p>

Noninterrupting keyevents while preserving individual keystrokes
|
<p>I am designing a keyboard interface through javascript, and I want to define keystroke combinations, like shift+rightkey or ctrl+tab. But after tinkering with javascript, as seen <strong><a href="http://jsfiddle.net/Arcym/ENUj2/7/" rel="nofollow">here</a></strong>, I've noticed that all keyevents are interrupting. In the provided example, if you go to hit the shiftkey while holding down the rightkey, the functionality of the rightkey is interrupted!</p>
<pre><code>v = 1; /*v is the variable of velocity.*/
window.addEventListener("keydown", function(event)
{
if(event.keyCode == 39) /*39 is the keycode of rightarrowkey.*/
{
//moves an element by the velocity.
var keystroke = document.getElementById("keystroke");
keystroke.style.left = parseInt(keystroke.style.left.slice(0,-2))+v+"px";
}
if(event.keyCode == 16) /*16 is the keycode of shift.*/
{
//increases the velocity of the element by four.
document.getElementById("keystroke").style.borderColor = "red";
v = 4;
}
}, false); //but hitting the shiftkey while hitting the rightkey interrupts..!
</code></pre>
<p>I also experimented with recording all keystrokes through an object which is then iterated through at a designated interval for defined keystrokes, as seen <strong><a href="http://jsfiddle.net/Arcym/kjkCc/3/" rel="nofollow">here</a></strong>. But this system of handling the keyboard doesn't <em>preserve</em> the individual keystrokes; if I hit a key too fast, it may not be considered, or if I hold a key for too long, it may be overconsidered!</p>

How often do you find javascript disabled on browsers?
|
<p>I have started using ajax/jQuery in our websites / application. There are many plugins that support degrading the javascript to browsers that dont have javascript enabled and techniques to support this. What are peoples thoughts on javascript support, we build applications rather than just websites and are looking to just support javascript enabled browsers as a pre-requisite assuming that most people or companies have javascript enabled.
Do you find most people have javascript? do you monitor the percentage of javascript/non-javascript browsers (I guess this can be done with website stats) and what are the numbers regarding this?</p>

<p>I'm trying to create a paycheck calculator, but when I enter the hourly rate and number of hours and hit calculate, all I'm getting is <em>undefined</em> in my totals table. Here is my javascript:</p>
<pre><code>var $ = function (id) {
return document.getElementById(id);
}
function updateTotal () {
var rate;
var hours = parseFloat( $("numHours").value);
var regularHours;
var overtime;
var doubletime;
//begin determine hourly rate
function checkJob () {
if ($('job').value == 'job0') {
rate = 0;
}
if ($('job').value == 'job1') {
rate = 12;
}
if ($('job').value == 'job2') {
rate = 10;
}
if ($('job').value == 'job3') {
rate = 11;
}
}
//calculate hours breakdown
function checkHours () {
if (hours.value <= 40) {
regularHours = hours.value;
overtime = 0;
doubletime = 0;
}
if (hours.value < 60) {
regularHours = 40;
overtime = hours.value-40;
doubletime=0;
}
if (hours.value >=60) {
regularHours = 40;
overtime = 20;
doubletime = hours.value-60;
}
}
checkJob();
checkHours();
var salary = (regularHours * rate) + (overtime * (rate * 1.5)) + (doubletime * (rate * 2))
//display amounts
$('regularHours').innerHTML = regularHours;
$('overtime').innerHTML = overtime;
$('doubletime').innerHTML = doubletime;
$('salary').innerHTML = "$ " + salary;
}
</code></pre>
<p>I'm sure I'm missing something silly, but I've been staring at this code for days and can't figure out what I'm doing wrong. Thanks for looking!</p>
