<p>I am guessing it is the Server API being Apache 2.0 Handler and CGI, if this is right, can anyone point me to a cheat sheet or any documentation on the Idiosyncrasies between the two.</p>

<p>As you can see here in <a href="http://white.codeplex.com/" rel="nofollow">http://white.codeplex.com/</a> , it's a powerful framework for automatic functional tests.</p>
<p><strong>Fact</strong>:
Actually, framework is intended to work with calling strongly typed control which are present in a form.</p>
<p><strong>Question</strong>:
It's possible to get a PRECISE control by using the mouse coordinates?</p>
<p><strong>Possible Way:</strong>
I have actually found a possible solution, but it lacks of perfomance, of course.
The way is:</p>
<p>1: Get Window</p>
<p>2: Get all controls of window ( filtered by Text/Edit/Button Control Types )</p>
<p>3: with linq get the control which actual Bounds (x,y,width,height) contains the mouse
location</p>

4,095,103 | 4,095,104 | how can I get the position of a cell in a table using javascript? | <p>By position I mean, how many columns are to the left of the cell and how many rows are on top of it. What I need exactly is two functions:</p>
<pre><code>function FindColPos(element)
{
/* find column position */
return colPos;
}
function FindRowPos(element)
{
/* find row position */
return rowPos;
}
</code></pre>
<p>the functions MUST be written that way, I can't add other stuff to my document like ID's since I only have access to the head of the document where I would insert the javascript functions. (All this is part of another project in C#). The element passed to the function would be a cell in a row (a <code><TD></code> element) but it would be better if I can pass any element inside the <code><TD></code> and the function can recognize the parent <code><TD></code>. I'm not advanced enough on javascript to figure it out myself. I actually don't even know if it's possible. Hope you can help.</p>

1,255,427 | 1,255,428 | How to create multiple objects based on frequency and date | <p>for some reason, I am unable to figure how to code it in a clean way.
I have a task object and this object has a start date and end date. I want to pass this object to method that will take this task, clone it X number of times according to the frequency and set its start date to the occurance date.</p>
<p>Offcourse, things can be much better illustrated by examples:
So lets say I have task that has start date of June 1 ,2012 and end date of September 15, 2012. The frequency is set to monthly. I want to pass this task to a method that would create an array of 4 tasks for me (June, July, Aug, September) of whose the start date is set to the first of the respective month</p>
<pre><code>ArrayList<task> spawnTasks(Task task, Frequency Monthly){
ArrayList<Task> arr = new ArrayList<Task>();
Task TaskJune = task.clone();
TaskJune.setStartDate("June, 1, 2012");
Task TaskJuly = task.clone();
TaskJuly.setStartDate("July, 1, 2012");
Task TaskAug = task.clone();
Taskaug.setStartDate("Aug, 1, 2012");
Task TaskSept = task.clone();
TaskSept.setStartDate("Sept, 1, 2012");
}
</code></pre>
<p>So as you can see I created the task once a month because frequency is monthly ( I can have biweekly or monthly only) and it happened on the 1st because thats the start date and it never exceeded september because the enddate is sept 15.</p>
<p>I know I have to use Calendar and loop to do it but I just can't figure it out</p>

5,393,361 | 5,393,362 | Any ideas about the best work around for __new__ losing its arguments? | <p>So, I only realised today that <code>__new__</code> is deprecated for receiving arguments, as of python 2.6 (it isn't mentioned in the documentation, which is also not true in terms of the behavior of <code>__new__</code> calling <code>__init__</code> as far as I can see). This means my functional code has started raising warnings, and I want to rid myself of them. But I can't see an elegant way to work around.</p>
<p>I have a bunch of classes that perform optimizations when they are constructed. So I have</p>
<pre><code>class Conjunction(Base):
def __new__(cls, a, b):
if a == True:
return b
elif b == True
return a
else:
return super(Conjunction,cls).__new__(cls, a, b)
</code></pre>
<p>And so on (real versions cover lots more cases). So unlike what Guido says in <a href="http://mail.python.org/pipermail/python-dev/2008-February/076854.html" rel="nofollow">this response</a> (the only reference to it I can find), my <code>__new__</code> method <em>does</em> use its arguments, and <em>cannot</em> be replaced by an overridden <code>__init__</code> function.</p>
<p>The best I can do is to split this in two:</p>
<pre><code>def Conjunction(a, b):
if a == True:
return b
elif b == True
return a
else:
return ConjunctionImpl(a, b)
class ConjunctionImpl(Base):
# ...
</code></pre>
<p>But that is plain ugly and stinks to high heaven. Am I missing an elegant way to have a class constructor return some arbitrary object based on the constructor parameters it is given?</p>

<p>So, if I understood right, the main difference between these two is that in the first example, gunRobot has a constructor property which points to Robot, whereas in the second example, laserRobot has a construtor property which points to Object. Both don't add anything to their prototype, right?</p>
<p>Now, if I change the first example to:</p>

}
Robot.prototype.fire = function() {
alert('Firing ' + this.weapon + 'projectile.');

var gunRobot = new Robot('gun');

<p>gunRobot's constructor property points to the Robot constructor, whose prototype property has a property fire. Now, if I call</p>
<pre><code>gunRobot.fire();

<p>as, gunRobot doesn not have a fire property, the next prototype up in the prototype chain is visited and checked for a fire property, right?</p>

2,629,781 | 2,629,782 | Check the type of derived class | <p>In my program I have a class named Entity. Another class Invader inherits Entity. Since I want to have 4 different kinds of invaders, I declare classes Invader1, Invader2, Invader3 and Invader4 which inherit from Invader. Now I declare a Entity pointer type vector to store all Invaders like:</p>
<pre><code>entities.push_back(new Invader4());
entities.push_back(new Invader3());
entities.push_back(new Invader2());
entities.push_back(new Invader1());
entities.push_back(new Invader0());

<p>When I check the type of the element in entities at runtime, say</p>
<pre><code>typeid(*entities->at(index))
</code></pre>
<p>It may return one of the 4 kinds of invaders. In entities there are also other objects which inherit Entity. So i just want to check if the type of the object is Invader or not, I don't want to know if it is Invader1, Invader2, etc.</p>
<p>How I can achieve this?</p>

<p>Basically, I couldn't not find an easy solution to this issue. I tried updating my dataGrid to a gridView control and even that (for my particular issue) was difficult. I wound up un-doing all the changes and just adding another grid that had just the data I wanted for the requirement. </p>
