<p>I have to make a function call from one program to another program (separate package). Now my question is, can i have a common Queue in the called program in which all the calling requests will be queued up ???? is it possible to maintain a queue??</p>
<p>Example.</p>
<pre><code>package1:
public class Callingprogram
{
public static void main(String args[])
{
CalledProgram cp=new Calledprogram();
cp.function(hashset);
}
}
package2:
public class Calledprogram
{
public void function(Hasheset hs)
{
here i am going to make use of the hashset sent by them
}
}
</code></pre>
<p>now here by i repeat my question :can i make any queue in Calledprogram such that it keeps track of all the calls made by Callingprogram and serves one by one...if so can i have a sample code such that i can proceed further....</p>
<p>Thank you..</p>

2,306,755 | 2,306,756 | I left Python learning because of Python 2 vs 3. Please Help | <p>I wanted To learn how to program for the first time.
Because i`m mainly practice on IT and Security, I choose to start with Python.</p>
<p>But, As is started to learn Python 3, I came to realize that Non of the modules I wanted to use were ported to Python 3, and even Django (one of the main reasons I wanted to learn python) and IronPython does not support python 3.</p>
<p>From my view, <strong>Python is not recommended for newbies</strong> because 1) Python 2 is about to be "<strong>out of future support</strong>" (the 2.7 is the last one). and 2) <strong>the Python 3 is not supported by the all important modules and frameworks</strong>...
So - someone who wants to learn python from scratch and not wasting time on a version that is about to be out of support (2), as no any good options (nor 2 or 3 version)...</p>
<p><strong>Please correct me if I`m wrong (and before I move to C# :) ).</strong></p>

4,033,984 | 4,033,985 | Best Place to Filter Inputs? | <p>I am wondering where the best place to filter user submitted input is. In regards to filter, I am talking about <a href="http://php.net/manual/en/function.filter-var.php" rel="nofollow">filter_var</a> and <a href="http://www.php.net/manual/en/function.filter-input.php" rel="nofollow">filter_input</a>.</p>
<p>I've come up with three scenarios:<br/></p>
<ol>
<li>Filter data from POST/GET, and pass filter data to function which takes it as-is.</li>
<li>Take raw data from POST/GET, and pass as-is to function where the function filters it.</li>
<li>Filter data from POST/GET, and filter is a second time in the function.</li>
</ol>
<p>Each of these methods has its advantages and disadvantages. I was looking for some insight into which may be best or standard practice.</p>
<p>Method 1 passes sanitized data to the function, and thus functions can be smaller not having to sanitize everything coming in. The downfall is if any other place your function is called and the data isn't sanitized, this can lead to problems. This simply requires good coding practice to remember to sanitize everything before passing to a function.</p>
<p>Method 2 you will never have to worry about your function dealing with unsanitized data, but the functions will be bigger.</p>
<p>Method 3 is the safest, but is wasteful. More code is written, and data may be sanitized multiple times as it passes through possibly various functions, wasting CPU resources and time.</p>

<p>I cant make the button or labels static in Form1 since they are in the designer and i dont want to use static.</p>
<p>And i dont want to create Form1 instance.</p>
<p>I also want to build for all the labels,buttons and other objects like that some function/s in the class so i can use them easy and so they will take effect when im running the program.</p>
<p>For now they are not exist in the new class that clear. </p>

<p>It keeps displaying the number 3 which is incorrect as if the user enters the current page for the first time then obviousl they don't start with session 3, they start with session 1, then 2 then 3.</p>
<p>So my question is how do I get "SESSION 1" to be displayed when the useer enters the page for the first time?</p>

970,944 | 970,945 | When to pull default values from a file? | <p>Not a specific coding question so much as program structure in general.</p>
<p>I'm one of those poorly self taught hobby programmers and I've got no idea what the best route is here. I want to create an object with 4 variables (name, objID, a, and b). For example:</p>
<pre><code>class myObj:
def __init__(self, objName, objID):
self.name = objName
self.objID = objID
self.a = 0
self.b = 0
</code></pre>
<p>My question/problem is I want the initial values for a and b to be pulled from a .txt file, based on the value of objID. I actually want more than just 2 variables, and I'll be creating hundreds of these objects with a dozen different types.</p>
<p>I don't think I want to read the file from this class, as I believe it will reopen the file every time an object is created, and I don't really like pulling it into a list/array/dictionary and passing it to the class because the myObj class will only be called from an object above it, also with dozens of instances.</p>
<p>To clarify - I plan to create 100 'topObj' objects, each with 5-10 'myObj' objects, with each 'myObj' having starting values (that will change later), pulled from a text file, and I don't know when and where to read the data from the text file without reading it 500-1000 times.</p>
<p>Hopefully this makes some semblance of sense.</p>

627,558 | 627,559 | JavaScript Internals 101: arrays are just a special type of objects | <p>Internally, JavaScript has only objects (and primitive types). Objects are <strong>unordered</strong> collection of <code>key:value</code> pairs, where <code>key</code> is string and <code>value</code> can be any JavaScript type.</p>
<p>Arrays, though on the outside look like normal arrays of any other language, are actually a special case of objects, with natively supported language syntax.</p>
<p>Each array is an object where the key is a number and value can be any type. The keys are managed by JavaScript itself so that we can manipulate the array as an <strong>ordered</strong> collection of values. This is the reason we can use arrays in a <code>for-in</code> loop too. Additionally, JavaScript provides standard array operations (length, indexOf, splice, slice, join) as methods that take use the numbered keys to do their thing.</p>
<pre><code>>>> typeof []
"object"
>>> Object.prototype.toString.call([])
"[object Array]"

<p>I have a div that is semi transparent and then want to switch it to not transparent. But the jQuery .delay(); method doesn't seem to work here. I've tried .fadeIn(); instead and that works with a delay but it doesn't work the changing classes.</p>

1,921,955 | 1,921,956 | How to access child element out of children()? | <p>I'd like to get the # of immediate children an element has, and then get the class of a child at a particular index. Something like:</p>
<pre><code>var index = 25;
var children = $("#myListElement").children();
if (index < children.length) {
if (children[index].hasClass("testClass")) {
alert("hi!");
}
}

<p>I think the syntax for .children() is ok, but how do I get the indexed element out of them in jquery style?</p>
<p>Thanks</p>

5,574,416 | 5,574,417 | How to reference object properties in another module | <p>I am relatively new to Python having used C# for many years and I'm hoping someone can help me with this question. I have a module called actuators.py that contains a number of classes for defining properties and methods for the servos I use in a robot project. In another module called robot.py, I instantiate my actuators like this:</p>
<pre><code>import actuators as Actuators
myActuators = Actuators.AllActuators()
</code></pre>
<p>This allows me to access the properties of my servos as long as I am in the robot.py module. For example, I can write:</p>
<pre><code>print myActuators.HeadTilt.MinPosition
</code></pre>
<p>to get the minimum value allowed for the servo that tilts the robot's head. So far so good.</p>
<p>Now I want to access these same values in a separate thread that is defined by a different module called tilt_head.py. I assume I need to import a reference to the robot.py module, but doing this ends up re-executing all the code in robot.py whereas all I really want is a static reference to the myActuators object. And I can't use</p>
<pre><code>from robot.py import myActuators
</code></pre>
<p>because myActuators is not a module.</p>
<p>In C#, I would do this using a declaration like this:</p>
<pre><code>public static Actuators myActuators;
</code></pre>
<p>which then allows me to reference myActuators in any other file within my project. Is there a way to do something similar in Python? If you need my actual code, I will be happy to post it.</p>
<p>Thanks!</p>
