private constructor usage in class
|
<p>If there is a private constructor, does the JVM insert a call to the super constructor? </p>
<p>I'm referring to the <code>super()</code> call in that private constructor.</p>
<pre><code>class Alpha {
static String s="";
protected Alpha(){
s+="alpha";
}
}
class SubAlpha extends Alpha{
private SubAlpha(){
s+="sub";
}
}
class SubSubAlpha extends Alpha{
private SubSubAlpha(){
s+="subsubAlpha";
}
public static void main(String[] args){
new SubSubAlpha();
System.out.print(s);
}
}
</code></pre>
<p>Here I don't get any compilation error. Here in the <code>SubSubAlpha</code> class there is private constructor. Is that compiler insert <code>super()</code> call in that if so, what happens in the <code>SubAlpha</code> class. Even there is private constructor. And if that is not accessed how the inheritance tree continues till the top.</p>

Getting the Variables of a function listed in the construct?
|
<p>I'm not an amazing developer so please bear with me, but I've begun using classes and functions, and I really like how I can write a library. A single page where all my PHP can go. I was thinking though, my life would be a millon times easier if I could check the variables of a function in the construct, and escape them all before running the function. That way, I wouldn't have to escape each variable for each function.</p>
<p>I'd need to be able to have the construct somehow check and see what the variables are in the function, and then escape them. </p>
<pre><code>so X = 'Variable for a function'
X = mysqli_real_escape_String($conn, X);
</code></pre>
<p>Could anyone please tell me if this is possible, and if not, what other options could you suggest? </p>
<p>P.S. I'm not advanced enough to use PDO yet, so please keep the advice to procedural programming.</p>
<p>Sorry, perhaps I'm not explaining this correctly. What I'm trying to do is eliminate the need to escape variables in my library that come when someone calls a function($vars). So the idea is to write some type of script within the __construct that will check the $vars and escape them before the function is ran. </p>
<pre><code>class users
{
function __construct()
{
//the idea is that i can somehow escape the variables within the function
//for the function that's being called
function magical_funtion_that_calls_all_variables()
{
foreach($var)
{
$var = mysqli_real_escape_string($conn, $var);
}
}
}
function register($user, $pass1, $pass2)
{

Need to know when it's a new day, i.e., when the time is 00:00:00
|
<p>I think I read somewhere that there's a system event for when the time changes (each second?) but are there other levels of granularity such as when the hour changes?</p>
<p>I have a <code>TabActivity</code> for a 7 day TV Guide - the indicator for the first (leftmost) always shows 'Today' with the others showing a three-letter day (Mon, Tue, Wed etc) obviously depending on what the day is today.</p>
<p>What I'd like to do is have the activity 'know' when midnight comes so it pops up a 'Re-loading please wait...' <code>ProgressDialog</code> and adjusts the indicator on each tab and the associated tab contents.</p>
<p>Is there a built-in system event that can help or is <code>AlarmManager</code> my best approach?</p>

Operators vs Functions in C/C++
|
<p>Someone recently asked me the difference between a C++ standard operator (e.g. new,delete,sizeof) and function (e.g. tan,free, malloc). By "standard" I mean those provided by default by the compiler suite, and <em>not user defined</em>. Below were the answers I gave, though neither seemed satisfactory.</p>
<p>(1) An operator doesn't need any headers to be included to use it : E.g. you can have a call to new without including any headers. However, a function (say free() ) does need headers included, compulsorily. </p>
<p>(2) An operator is defined as such (ie as a class operator) somewhere in the standard headers. A function isn't. </p>
<p>Can you critique these answers and give me a better idea of the difference?</p>

Check which php functions will work in a specific php version

At some point while writing my php project, I determined that it would need php verion 5.2 to work properly. I didn't document why. Now, a user is asking me what will break if they run my app on 5.1 and I simply can't remember.</p>
<p>Is there any automated way to check which functions will fail using 5.1. I looked at PHP_CodeSniffer, but I'm not sure that will do what I want. Any thoughts?</p>

How to have exceptions that doesn't need to be caught in Java?
|
<p>I would like to throw a custom exception that will be determined at runtime. Currently I have to either add throws to the function or surround it with a try catch. What I want is for this exception to not be caught at all. It is a fatal exception and will show the programmer the error and what he can do to fix it. This is for an abstract class checking if initialization has been run first. I would like it to act like a NullPointerException, as when it occurs the program crashes.</p>

<p>Is there another way to do this? All I need to do is remove the second overlapping frame in an image.</p>

Compare a dict to itself and remove similar keys efficiently
|
<p>I would like to compare elements in a dictionary to one another, and remove items according to some comparison criteria. And I'd love it to be efficient. I have a function that can do this, but it repeatedly copies the dictionay. Surely there is a superior way:</p>
<pre><code>mydict = {1:5,2:7,3:9,4:9,7:7,8:0,111:43,110:77}
def partial_duplicate_destroyer(mydict,tolerance):
for key1 in mydict.keys():
mydict_copy = mydict.copy()
for key2 in mydict_copy.keys():
if key2 - tolerance < key1 < key2 + tolerance and not(key1 == key2):
del(mydict[key1])
break
return mydict
print partial_duplicate_destroyer(mydict,2)
print partial_duplicate_destroyer(mydict,20)
print partial_duplicate_destroyer(mydict,200)
#correct output:
# {4: 9, 8: 0, 111: 43}
# {8: 0, 111: 43}
# {111: 43}

parseInt Alternatives for parsing numerical strings
|
<p>Assuming I have a numerical string:</p>
<pre><code>var foo = "0";
</code></pre>
<p>Assume I want to parse it as a number, and increment it assigning the value to <code>bar</code> (just an arithmetical example), I know I could do:</p>
<pre><code>var bar = parseInt(foo, 10)+1;
</code></pre>
<p>But I believe the above example could be simpler and more readable. Consider this example:</p>
<pre><code>//alternative 1
var bar = +foo+1;
</code></pre>
<p>And this one:</p>
<pre><code>//alternative 2
var bar = ++foo;
</code></pre>
<p>Both of these will also yield the same result for <code>bar</code> (the latter will also increment <code>foo</code>, but that's no problem).</p>
<p>My question is, by using one of these alternatives, would I be exposing my code to the same possible implementation-dependant flaws of using <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/parseInt" rel="nofollow"><code>parseInt</code></a> without specifying a <code>radix</code>/<code>base</code>?</p>
<p>Or are these safe to use as well?</p>

hide view in interface builder when there are multiple views
|
<p>This is probably a dumb question, but I can't seem to figure it out. In IB, if I have two UIViews, that are subviews of the main UIViewController.view that I basically show and hide depending on the user's input, is there a way to hide one of the views while working in IB. All the text/buttons are on top of each other so I can't really tell what's going on. Is there a way to just make that view and all its children hidden while I work on the other view? Thanks.</p>

Recursive implementation of permutations in Python
|
<p>I apologize that there have already been many posts about this problem. However, I am having a hard time seeing where I am going wrong in my own implementation. So I am trying to write a function that takes in a string and returns all of it's possible permutations in the form of a list. </p>
<p>Theoretically it should look like this: </p>
<p>allPermutations("abc...z") = [a + allPermutations(b,c,...z), b + allPermutations(a,c...z)...]</p>
<p>My current implementation, when tested on the String, "Hello", outputs a bunch of duplicate permutations. Can anyone help me see where I am going wrong. I appreciate your assistance!</p>
<p>Here is the Code:</p>
<pre><code>def allPermutations(strng):
if len(strng) ==1:
return [strng]
perm_list = []
for i in strng:
smallerStr = strng.replace(i,"",1)
z = allPermutations(smallerStr)
for t in z:
perm_list.append(i+t)
return perm_list

Fetching data from Internet in background and showing ProgressDialog or ProgressBar
|
<p>I am developing an application which require accessing a website for
data, and will show that data on device. I wants to fetch data from
Internet in background and show ProgressDialog or ProgressBar on
device and when application receive response from server app will
dismiss the dialog or bar and will show data .</p>
<p>For this i am using AsyncTask -</p>
<p>code for AsyncTask is as follows--</p>
<pre><code>ServerTask extends AsyncTask {
@Override
protected void onPreExecute() {
dialogAccessingServer = new ProgressDialog(ctx);
dialogAccessingServer.setMessage(shownOnProgressDialog);
dialogAccessingSpurstone.show();
}
@Override
protected ServerResponse doInBackground(String... urlArray) {
String urlString = urlArray[0];
HttpResponse serverResponseObject = null;
//finding HttpResponse
return serverResponseObject;
}//end of doInBackground
@Override
protected void onPostExecute(HttpResponse serverResponseObject){
dialogAccessingSpurstone.dismiss();
}
}
</code></pre>
<p>and calling this code as follows--</p>
<pre><code>ServerTask serverTaskObject = new ServerTask();
serverTaskObject.execute();
HttpResponse response = serverTaskObject.get();
</code></pre>
<p>//performing operation on response</p>
<p>but ProgressDialog is not shown.(I guess the reason for it is the
thread is not complete and android invalidate only when thread has
completed).</p>
<p>My Questions --
1- If my guess is right ? If yes then how I should implement it?
2- If there is any other better way to do this?</p>
<p>thanks </p>

<p>What happens to a dataset when your done using it. For example if I create and fill a dataset for a grid, when the user leaves that page or logs out I assume the dataset is still in memory?</p>
<p>Does each user get their own instance of the dataset? In other words, if 2 users hit the same page that uses a grid are they each served their own instance of the dataset from server memory?</p>

C# - Am I replacing perfectly good code?
|
<p>I had a quick function to format a date, here it is:</p>
<pre><code>public static string archiveServerDateTime(string datetime)
{
DateTime tempDateTime = DateTime.ParseExact(datetime,"dd.MM.yyyy HH:mm:ss", null);
return tempDateTime.ToString("yyyy/MM/dd:HH:mm:ss");
}
</code></pre>
<p>only to find the output of the function = 2009.10.22:16:21:03, and amazingly this is only on 1 production server, test server worked perfectly fine......</p>
<p>So now I rewrote the function to old school style:</p>
<pre><code>public static string archiveServerDateTime(string datetime)
{
DateTime tempDateTime = DateTime.ParseExact(datetime,"dd.MM.yyyy HH:mm:ss", null);
string yearPart = Convert.ToString(tempDateTime.Year);
string monthPart = Convert.ToString(tempDateTime.Month).PadLeft(2,'0');
string dayPart = Convert.ToString(tempDateTime.Day ).PadLeft(2, '0');
string hourPart = Convert.ToString(tempDateTime.Hour).PadLeft(2, '0');
string minutePart = Convert.ToString(tempDateTime.Minute).PadLeft(2, '0');
string secondPart = Convert.ToString(tempDateTime.Second).PadLeft(2,'0');
return yearPart + @"/" + monthPart + @"/" + dayPart + ":" + hourPart + ":" + minutePart + ":" + secondPart;
//return tempDateTime.ToString("yyyy/MM/dd:HH:mm:ss");
}
</code></pre>
<p>So I ask you ladies and gentlemen, was I replacing perfectly good code to begin with, or is this a Microsoft bug of some kind? Can we really trust these new language features that are seemingly not so rock solid, or am I just missing something?</p>

Global Variables Bad

<p>Ok after reading this article and also some of the examples I am still not clear on what global variables mean. So its say private variables in your class are global?</p>
<p><a href="http://www.c2.com/cgi/wiki?GlobalVariablesAreBad" rel="nofollow">http://www.c2.com/cgi/wiki?GlobalVariablesAreBad</a></p>
<p>So can someone explain this to me in simple terms the context. Does this mean even private fields at the top of your class? I'm not clear on the definition of a "global variable" so that I can distinguish if I'm doing something "bad" in my classes.</p>

Making part of the view transparent/overlay while the rest isn't
|
<p>I'd like to show an overlay view similar to what you see when you perform a 'Search in Contacts app where the SearchBar is visible under the toolbar while the gray overlay covers up all of the content below.</p>
<p>For my view, I'd like to have an UITextField and button shown visible while the rest of screen is gray with the rest of the existing contents as grayed-over and no SearchBar.</p>
<p>Things I tried:</p>
<ol>
<li><p>I can have one view that encases
both UITextField and button with the
view's alpha level set to 0.5. But
this yields grayed appearance for
everything, including the
UITextField and button, which is not
what I'm trying to achieve. </p></li>
<li><p>I then tried two child views within
a parent UIView, with one subview
containing the controls while the
other one is blank. Set the parent
UIView to have 0.5 alpha -> this is
not right either.</p></li>
<li><p>Continuing with two child views
within a parent UIView, set the
parent view to have alpha of 1.0 and
then the the blank-view to have an
alpha level of 0.5, it's still not
right.</p></li>
</ol>
<p>So what's a good way to achieve this?</p>

Passing object references between modules

The log outputs a context2d reference from myApp.init(). Can I not expose a private object variable in the return statement of the myApp module? I thought I was beginning to understand the basics of this language but am getting frustrated by this seemingly simple concept. Thanks for your help.</p>

myApp.init();
console.log(myApp.ctx); // logs undefined
};
var myApp = (function () {
var canvas,
ctx,
init = function () {
canvas = document.getElementById("canvas");
ctx = canvas.getContext('2d');
console.log(ctx); // logs valid context2d object
};

How to package an ASP.NET application to prevent customers from modifying it?
|
<p>Is there a tool or some general approach to packaging all the files of an ASP.NET application into binary form to prevent modification once its deployed? I am thinking there would be a set of signed binaries and a config file for settings that we allow the customer to modify. Has anyone attempted this, is it even possible?</p>
<p>I would pay a reasonable amount for a slick commercial product that did this with minimal hassle.</p>
<p><strong>UPDATE</strong></p>
<p>Sorry, from the answers I can see that I wasn't clear. I meant literally packaging ALL files, not just the code files. This means aspx, scripts, images etc. I'm not trying to prevent reverse engineering... this is a supportability issue, i.e. to avoid dealing with problems brought about by customer messing with the files.</p>

In short I have to create two layouts each on has map and at run time i have to set visibility and one after other.
For that i create one XML layout which has linear layout as root layout and then create two separate relative layouts to hold two maps but it gives me error that unexpectedly closed.</p>

<p>Because of that I have to change all my imports to accommodate for this change.</p>
<p>I wanted to make settings file in the main folder and include it in every file and call exec("import %s.modulexxx" % path).</p>
<p>But the problem is how to access settings file (because I also need to know my directory path).</p>
<p>Is there a way to include some file below, for eg. :</p>
<p>if it is main->module1->module2 , in module2 I could include ../../settings.py
so if it changes to project_name->main->module1->module2 it would still work because it would still be 2 level below.</p>
<p>Any help?</p>

Get the folder path under cursor?
|
<p>I'am working on my small project: Crypt container. To unlock it - just plug-in specifig usb flash-drive and unplug it to lock container. </p>
<p>So, GUI of program is very simple - just ListView. If you want to add files into continer - drag'n'drop items to them.</p>
<p>But i have a problem - when user want to decrypt his file, he drag them in container and drop to desktop (or specific folder). And my task is to know, where user wants to put a file. If he drag file to folder - i should unpack it to folder, if he drag it to flash-drive - i should unpuck it to flash-drive.</p>
<p>Yes, i found one solution of my problem: <a href="http://www.codeproject.com/KB/files/DragNDrop.aspx" rel="nofollow">http://www.codeproject.com/KB/files/DragNDrop.aspx</a> , but i realy not understand that mechanism with tempDirectoryWatcher and Hashtables. </p>
<p>Maybe somebody know easy way to get path to object (folder, drive, etc.) under cursor?</p>

Define "custom" integer-based type?
|
<p>I have a program that is interfacing with an external library that, among other things, has an unsigned 12-bit value packed in a larger struct.</p>
<p>This used to be 8 bits, so we simply marshaled it as a byte.</p>
<p>Now that it's 12 bits... I can use a ushort, but that opens up issues of (a) range checking and (b) marshaling.</p>
<p>Is there a simple way of implementing a constrained numeric type like this, where I don't have to override every assignment and comparison method?</p>

jQuery's if $('#foo').is(':hidden') and $('#foo').slideUp() not working when "display: none !important"?
|
<p>This one works: </p>
<blockquote>
<p><a href="http://jsfiddle.net/fGnL7/3/" rel="nofollow">http://jsfiddle.net/fGnL7/3/</a> </p>
</blockquote>
<p>using</p>
<pre><code>$(document.body).click(function () {
if ($("div:first").is(":hidden")) {
$("div").slideDown("slow");
} else {
$("div").slideUp("slow");
}
});
</code></pre>
<p>but if for some reason, the element is made <code>display: block</code> by some framework (by Compass/Blueprint's <code>+clearfix</code>), so
I used </p>
<pre><code>display: none !important
</code></pre>
<p>to make it not show on page at first, and then the code will not work.</p>
<blockquote>
<p>sample: <a href="http://jsfiddle.net/fGnL7/4/" rel="nofollow">http://jsfiddle.net/fGnL7/4/</a></p>
</blockquote>
<p>I also tried adding <code>$("div").css({display: 'block'});</code> or even <code>$("div").css({display: 'block !important'});</code> before it called <code>slideDown()</code> and it doesn't work either. </p>
<blockquote>
<p>sample: <a href="http://jsfiddle.net/fGnL7/7/" rel="nofollow">http://jsfiddle.net/fGnL7/7/</a></p>

<p>Is there a way around this?</p>

Generate start and ending datetimes in UTC based on a PST date
|
<p>I am taking in a parameter that is a date in PST timezone which will be in the format of "YYYY-MM-DD" (e.g. "2011-08-15"). This parameter is optional. I have 2 questions that I've been struggling with.</p>
<p>I need to calculate the start and end datetime in <strong>UTC</strong> for this date.</p>
<p>So if the inputted date is <code>2011-08-15</code>, I want to get the start and end datetimes:</p>
<p><code>2011-08-15 07:00:00</code></p>
<p><code>2011-08-15 06:59:59</code></p>
<p>(These are essentially the beginning and end of day)</p>
<p>Second, is to handle the case when the date is not passed in. I want to default to the current PST date them and start from there. So if the current datetime is <code>2011-08-01 10:00:00</code>, I want to get the same start and end datetimes similar to the first scenario except it's based on the inputted date.</p>
<p><code>2011-08-01 07:00:00</code></p>
<p><code>2011-08-01 06:59:59</code></p>
<p>I've been pulling my hair out dealing with date and datetime conversions. I'm sure I'm missing something super straightforward.</p>

Custom HttpHandler never running
|
<p>Forgive me if this is basic. I've never made one before and can't seem to figure out why it's not working. I wrote a little handler to do some parsing on CSS files. I added this:</p>
<pre><code> <system.web>
<httpHandlers>
<remove verb="*" path="*.css"/>
<add verb="*" path="*.css"
type="MyNameSpace.CssRelativePathHandler,CssRelativePathHandler" />
</httpHandlers>
</system.web>
</code></pre>
<p>Nothing ever happens. CSS files get parsed normally. No errors, nothing, the code never runs. What am I missing? Shouldn't this cause the handler to be used when *.css files are served? (I added the "remove" later, since I thought perhaps I needed to do that to override a built-in hander, again, no difference either way).</p>
<p>This is IIS 6. I added the IIS 7 code anyway (after searching for answers) but makes no difference.</p>
<pre><code> <system.webServer>
<handlers>
<add name="CssHandler" verb="*" path="*.css"
type="MyNameSpace.CssRelativePathHandler,CssRelativePathHandler" />
</handlers>
</system.webServer>

Pointer to member variable
|
<p>The following program output is always 1 1 1. In "Inside the c++ object model" book, it is mentioned that it will give offset. The purpose is also to find out object layout. But, I am confused with the output. Used g++ 4.5.2 </p>
<pre><code>class Test
{
public:
float a;
float b;
float c;
};
int main()
{
float Test::*ptr = &Test::a;
float Test::*ptr1 = &Test::b;
float Test::*ptr2 = &Test::c;
cout<<ptr<<endl;
cout<<ptr1<<endl;
cout<<ptr2<<endl;
return 0;
}
</code></pre>
<p>Output:</p>
<pre><code>1
1
1
</code></pre>
<p>Edit(Follow up question):
In the book it is mentioned that <code>origin.y = 0</code> can be transformed to <code>&origin + (Point3d::y-1)</code> where origin is an object to Point3d and y is member variable of class Point3d. Though When I compiled it gave me compilation error.</p>

How to confirm only html files exist in a given folder and if not then how to prompt the user to specify a folder with only html files within
|
<p>I would like to create a python script that will do 3 things: <li>1) Take user input to navigate to a file directory</li><li>2) Confirm the file contents (a particular set of files need to be in the folder for the script to proceed)</li><li>3) Do a Find and Replace</li></p>
<p>The Code as of now: </p>
<pre><code>import os, time
from os.path import walk
mydictionary = {"</i>":"</em>"}
for (path, dirs, files) in os.walk(raw_input('Copy and Paste Course Directory Here: ')):
for f in files:
if f.endswith('.html'):
filepath = os.path.join(path,f)
s = open(filepath).read()
for k, v in mydictionary.iteritems(): terms for a dictionary file and replace
s = s.replace(k, v)
f = open(filepath, 'w')
f.write(s)
f.close()
</code></pre>
<p>Now i Have parts 1 and 3, I just need part 2.</p>
<p>for part 2 though I need to confirm that only html files exist in the directory the the user will specified otherwise the script will prompt the user to enter the correct folder directory (which will contain html files)</p>
<p>Thanks </p>

Using .join() in Python
|
<p>Very simple and quick question. Take this list for example: </p>
<pre><code>a = ['hello1', 'hello2', 'hello3']
','.join(a)
</code></pre>
<p>I would like to have 'and' instead of a comma before the last element of the list. So I would get:</p>
<blockquote>
<p>hello 1, hello 2 and hello 3</p>
</blockquote>
<p>instead of....</p>
<blockquote>
<p>hello 1, hello 2, hello 3</p>
</blockquote>
<p>Is there a way to accomplish this using <code>.join()</code>? I know I can just type it in the list for a simple example like this, but the list I need in my actual program comes from user input.</p>

Android way to use Bitmaps from Camera.setPreviewCallback

private long timestamp=0;
public synchronized void onPreviewFrame(byte[] data, Camera camera) {
Log.e("CameraTest","Time Gap = "+(System.currentTimeMillis()-timestamp));

</code></pre>
<p>I have a camera View, and in front of a simple View (where I can draw something).
I'd like to draw on the front of View, when I can find the face of a human.
But <code>mFaceBitmap</code> is ever and ever return null, why? </p>
<p>If this is a bad idea, how can I do this better?</p>

jQuery return false weird behavior
|
<p>I have a piece of jQuery code that toggles a description paragraph for a given td when users click on an anchor tag, see code below. My problem is that if I put the return false statement as shown, the code works fine in IE but in FF it would not show the description at all, which is expected. When I put the return false after the toggling it works fine in FF but in IE it would show the description and then hides it right away. Is there any way to get it to work properly in both??</p>
<p>Thanks in advance.</p>

return false;
$(this).parent()
.parent()
.find(".description")
.animate({ opacity: "toggle", "slow");

jQuery modal stack with ajax forms
|
<p>I have a simple function that opens a url inside a modal and there can be multiple modals on the page. In one such example the user would open up a modal from another modal say to edit some content that is currently being show in the first modal.</p>
<p>The problem is when the form inside the second modal is submitted (using ajax) is how to refresh the first modal. I would need to know two things which modal to refresh and what content to use to refresh the modal with.</p>
<p>Has anyone ever done anything like this before? Has some ideas?</p>
<p>The only idea I could come up with was to record the indexes and urls each time a user clicks an ajax modal link and store them in an array and then when the form submits check if the parent modal of the form index matches one of the arrays and then use the values to refresh the correct modal with the url that is also stored inside the array. But this is very long-winded and quite sloppy and the results are unpredictable.</p>
<p>Anyone got any other/better solutions?</p>
<p>Cheers</p>

<p>Is it possible with some android function? I know I could do something like send an email, or make an hidden connection to my server but I'd like a more "standard" way (moreover these hidden methods could not be liked by some user)...moreover error logs are sent so there IS a mechanism, problem is if I can attach to it or not</p>

<p>Issue is that user may link to an image that is of extremely large height and width which is more than the height and width of the div it is in causing some overflow layout issues</p>
<p>Is there anyway I can resize the image such that it still fit in the div without losing the aspect ratio?</p>
<p>Alternatively can I use CSS something like set overflow to display scroll bar if that happens?</p>
