4,663,503 | 4,663,504 | How do you store an int or other "C# value types" on the heap (with C#)? | <p>I'm engaged in educating myself about C# via Troelsen's Pro C# book.</p>
<p>I'm familiar with the stack and heap and how C# stores these sorts of things. In C++, whenever we use <code>new</code> we receive a pointer to something on the heap. However, in C# the behavior of <code>new</code> seems different to me:</p>
<ul>
<li>when used with value types like an int, using <code>new</code> seems to merely call the int default constructor yet the value of such an int would still be stored on the stack</li>
</ul>
<p>I understand that all objects/structs and such are stored on the heap, regardless of whether or not <code>new</code> is used.</p>
<p>So my question is: how can I instantiate an <code>int</code> on the heap? (And does this have something to do with 'boxing'?)</p>

{
return new MyClass(i * m.Value);
}
public static MyClass operator *(MyClass m, int i)
{
return new MyClass(m.Value * i);

</code></pre>
<p>What's the logic behind this?</p>
<hr>
<p><strong>Additional Descriptions:</strong> Dear @Marc's answer about Vector and Matrix multiplication was good <strong><em>if and only if we assume operand types are different !!! It's evident that we can define <code>*</code> operator only once to perform Vector or Matrix multiplication.</em></strong> So I think this is not the answer.</p>
<blockquote>
<p>@Marc: Order is sometimes important in operators.</p>
</blockquote>
<p>Yes, but this is not equivalent with <em>Order is sometimes important in operands!</em> The above sentence may be used in case of using <code>+</code> operator before (or after) <code>*</code> operator that it will cause to different results. For example:</p>
<p><code>0 + 2 * 2 != 0 * 2 + 2</code></p>
<p>♦</p>
<p>Assume that we've defined <code>*</code> operator as:</p>
<pre><code>public static MyClass operator *(MyClass m1, MyClass m2)
{
return new MyClass(m1.Value * m2.Value /* or some other kind of multiplication */);
}
</code></pre>
<p>We <em>can not</em> define it again.</p>
<pre><code>public static MyClass operator *(MyClass m2, MyClass m1) { ... }
</code></pre>
<p>If so, compiler would tell us that type <code>MyClass</code> already defines a member called 'op_Multiply' with the same parameter types.</p>
<p>Now, we can use this operator in two ways: <code>m1 * m2</code> or <code>m2 * m1</code> and they may have different results which depend on multiplication procedure.</p>

<p>I just saw <a href="http://stackoverflow.com/a/672886/888051">a post</a> in which I found something I never saw before, in short here it is:</p>
<pre><code>class A {
public:
int _x;
};
void foo(A *a_ptr, int *m_ptr)
{
cout << (*a_ptr).*m_ptr << endl; // here
}
int main()
{
A a;
a._x = 10;
foo(&a, &A::_x); // and here
}
</code></pre>
<p>How could it be done? Pass in <code>&A::_x</code>, and later refer it using <code>(*a_ptr).*m_ptr</code>?</p>
<p>I thought, <code>&A::_x</code> will always refer to the same address, but different objects have different <code>_x</code>, how could it be done?</p>

<p>I am also facing same problem, I have a huge list where i need to do extensive calculation in <code>getView()</code> which are unavoidable, my list contains live data which gets generated at the time of displaying list, so i can't avoid these calculation other than doing them in <code>getView</code> function. </p>
<p>I don't know why <code>getView</code> method is getting called when i am switching focus from/to list view, cause of <code>getView</code> is getting called at the time of changing the focus and i am doing calculations in <code>getView</code> my application gets stuck for 2-3 seconds and then it switches focus from/to list view. </p>
<p>Is there any way by which we can avoid this behavior of list view.</p>

1,007,626 | 1,007,627 | Adding Javascript to a website | <p>I have been making websites by myself for a few months now and although I understand the concept of how to add Javascript to a site, I am really struggling with how to best go about it and would have liked some experienced developers opinions/advice.</p>
<p>I have read countless times on SO that it is best practice to build a plain site first and then go about adding Javascript. That way the site will work pretty much no matter what. It's a great idea for stuff like animations, basically, Javascript which acts on the page.</p>
<p>But, if you have a site with server generated content. And say, that to shorten load time on your pages you would like to then have part of your content loaded via ajax calls. How do you go about adding that to the site?</p>
<p>As far as I understand you cannot know at the server whether your client has Javascript enabled or disabled when the page refreshes... so you can't leave content out at the server. But if you send all of it to the client then you don't need an ajax on the page anymore.</p>
<p>How do you normally go about it in this case? Do you make links for and versions and signal the server which version to load that way?
But that still doesn't tell you whether or not the user will have scripts enabled at refresh or not...</p>
<p>Or do you just do like facebook and ebay and ignore users with scripts disabled?</p>

4,158,018 | 4,158,019 | Javascript: Adding days to any date | <p>I've read through a number of topics now and have not found one quite on point.</p>
<p>Here's what I'm trying to do:<br>
1) Parse a bill date that is provided in the format mm/dd/yy and is frequently not today<br>
2) Add a variable number of days to the date. The terms are saved in the dueTime array below. I limited it to 30 days here.<br>
3) Based on the bill date + the payment terms, calculate the date that the bill is due and return that in the mm/dd/yy format. </p>
<p>Here's what I've tried. The information I pass into new Date is what I expect, but the output from new date is never what I expect.</p>
<p>Thanks for your help.</p>
<pre><code><html>
<head>
<script>
function calculateDueTime(){
var billDate = document.getElementById('billDateId').value;
var key = document.getElementById('termsId').value;
var dueTime = new Array();
dueTime[1] = 30;
var billDate = billDate.split('/');
var newDate = new Date( parseInt( billDate[2] ) + '/' + parseInt( billDate[0] ) + '/' + ( parseInt( billDate[1] ) + parseInt( dueTime[key] ) ) );
document.getElementById('dueDateId').value = newDate.toString();
}
</script>

996,807 | 996,808 | ASP.NET gone FUBAR on a production machine | <p>Today we tried to put an ASP.NET application I helped to develop on yet another production machine. But this time we got a very weird error.</p>
<p>First of all, from all the ASP.NET pages, only Login.aspx was working. The rest just show a blank screen when they should have redirected to Login.aspx. The HTTP response is 200, but no content.</p>
<p>Even worse - when I try to enter the address of some inexistent ASPX page, I also get HTTP 200! Or, when I enter gibberish in some existing ASPX page code (which should have been accessible without login) I also get HTTP 200.</p>
<p>If I enter the name of some inexistent resource (like asdasd.jpg), I get the expected 404.</p>
<p>The redirect to login page is written manually in Global.asax. That's because the application has to use some alternate methods of authentication as well, so I can't just use Forms Authentication. I would suspect that Global.asax is failing, if not for the working Login page.</p>
<p>Noteworthy facts are also that this machine is both a Domain Controller and has SharePoint installed on it. Although the website in question is listed in SharePoint's exception list.</p>

101,481 | 101,482 | Performance implications when using singleton from non-singletons in Java? | <p>Suppose there are several instances of a class simultaneously calling service methods defined in a singleton class. </p>
<p>Can some one explain to me what happens at the low level when a method is called in a singleton when that method is already being executed by some other instance of the class? I am thinking that JVM would block the caller until the current caller is done with the method. Is this right?</p>
<p>Would it improve performance if we move some of the methods in the singleton class to define them within the class needing such methods?</p>
<p>Would it improve performance if singleton is changed to non-singleton allowing each instance of a class needing to call the service methods in another class to create its own instance of the service class?</p>
<p>Assume of course singleton is stateless.</p>
<p>Consider the situation multiple threads calling service methods in the singleton.</p>

Screen flashes repeteadly in some interval so i have done that job on asynctask. Everything is working ok until i change my screen orientation (at runtime i.e i have settings preference in my project also where i can change orientation).
Here is the very rough code:</p>
<pre><code>static WindowManager.LayoutParams lp = MyClass.this.getWindow().getAttributes();
MyClass.lp.screenBrightness = MyClass.brightnessValue / 100.0f;
if(brightnessValue == 100.0f){
MyClass.brightnessValue = 1.0f;
}
else{
MyClass.brightnessValue = 100.0f;
}
handler.sendEmptyMessage(1); //because i can't access this from non ui thread so applying brightness on handler
</code></pre>
<p>//inside handler:</p>
<pre><code>case 1: MyClass.this.getWindow().setAttributes(lp);
break;
</code></pre>
<p>Any idea why code is breaking when orientation is changed</p>
<p>Edit: Ok after testing further i found that its changing brightness is not working after pause. I mean when i close activiity by pressing back and when i run app again screen flashing doesn't work. But if i start new activity and again press back to my main activity then screen flashing works. So my screen flashing is not wrking in 2 scenario:</p>
<blockquote>
<p>1) When i go back and exit app(i mean when i got to home screen or
other from my main activity)</p>
<p>2) When i change orientation mode to landscape by starting preference
activity then i press back and main activity starts in landscape mode.</p>
