How to add checkbox array to zip file for download from a form
|
<p>I am trying to get a foreach loop to give me the checkbox values (which have the file names for values) from my form, to be added to a zip file. </p>
<pre><code><input type="checkbox" name="download[0]" value="Fact_Sheet_1.pdf" />
<input type="checkbox" name="download[1]" value="Fact_Sheet_2.pdf" />
<input type="checkbox" name="download[2]" value="Fact_Sheet_3.pdf" />
<input type="checkbox" name="download[3]" value="Fact_Sheet_4.pdf" />
<input type="checkbox" name="download[4]" value="Fact_Sheet_5.pdf" />
</code></pre>
<p>Works fine if I click on one checkbox but when I tick more than one checkbox only one file gets added to the zip file.</p>
<p>My code is below. Any suggestions would be appreciated.</p>
<pre><code>if(isset($_POST['submit']) )
{
foreach ($_POST['download'] as $key => $val) {
$filename = 'Fact_Sheets/' . $val;
}
}
system("zip -r files/zipfile $filename");

Dumping a Java program into a file and restarting it
|
<p>I was just wondering if it's possible to dump a running Java program into a file, and later on restart it (same machine)</p>
<p>It's sounds a bit weird, but who knows</p>
<p>--- update -------</p>
<p>Yes, this is the hibernate feature for a process instead of a full system. But google 'hibernate jvm process' and you'll understand my pain. </p>
<p>There is a question for linux on this subject (<a href="http://stackoverflow.com/questions/2134771/hibernate-a-process-in-linux">here</a>). Quickly, it's possible to hibernate a process (far from 100% reliable) with <a href="http://cryopid.berlios.de/" rel="nofollow">CryoPID</a>.</p>
<p>A similar question was raised in <a href="http://stackoverflow.com/questions/424341/are-there-any-java-vms-which-can-save-their-state-to-a-file-and-then-reload-that">stackoverflow</a> some years ago.</p>
<p>With a JVM my educated guess is that hibernating should be a lot easier, not always possible and not reliable at 100% (e.g. UI and files). </p>
<hr>
<p>Serializing a persistent state of the application is an option but it is not an answer to the question.</p>

False

What is the difference between Function.prototype.call() and Function.prototype.bind()?

<p>I went throught the MDN documentation, but I didn't really understand the difference between call() and bind(). They both seem to do the same thing - change the context of <code>this</code> inside a function. So what really is the difference between them? And which should be used when?</p>

Fading from one SPAN to another, ending on last, jQuery
|
<p>Greetings,</p>
<p>I am trying to fade in text spans one after another, fading each out before the next is faded in, using jQuery.</p>
<pre><code><p>IN
<span class="fadeText">spiring</span>
<span class="fadeText">nnovative</span>
<span class="fadeText">genious</span>
</p>
</code></pre>
<p>The spans will be set to hidden in CSS, trying fade from one span to the next and ending with the last still visible. I've tried several combinations using <code>$(".fadeText").each</code> and <code>fadeIn()</code>, <code>fadeOut()</code> but cannot seem to produce this effect.</p>
<p>Any help would be greatly appreciated</p>

Choose correct UIButton on dynamiclly created buttons without tags
|
<p>I am loading up a plist file and creating buttons based on this file. These buttons can change at any point during the application running (which will trigger an update of all the buttons etc).</p>
<p>One set of buttons represents a list of categories. So I may have a house button, car button, etc. No matter what button is pressed it will call my categoryButtonPressed:(id) sender function. I need to know what button called it and load a second set of data based on the button (category) that was pressed.</p>
<p>So if I press the house button, the function needs to load the house data, but how can I determine what button was pressed in that function. If I use tags I have to know that the house button is tag 1, car is tag 2 and so forth. BUT I don't know if there will even be a house button until I read that file. Do I need to code the tag into the plist file as well? </p>
<p>OR is there a way to loop through my Array of UIButtons and determine this? Any advice?</p>
<p>And last, if I create my own extended version of UIButton that added a "name" variable, would I would still be out of luck because the action would pass the UIButton base and comparing my extended class to the base would always fail correct?</p>
<p>Thanks for any and all help!</p>

Use eval() with different local scope
|
<p>I would like to know how it is possible to call eval() with data from a different local scope.</p>
<p>Something like:</p>
<pre><code>function doSomething() {
var y = 1;
print_and_eval('y+1');
}
function print_and_eval(data) {
print(data);
eval(data);
}
</code></pre>
<p><strong>Edit:</strong>
- It is safe to use eval() in my case. Please do not recommend this as a solution.
- The main problem is, that I have local variables in doSomething() which are not defined in print_and_eval(). The evaluation then leads to an 'ReferenceError: y is not defined' error.</p>
<pre><code>js> print_and_eval('var a = {x:1}')
var a = {x:1}
js> print_and_eval('print(a.x)')
print(a.x)
typein:3012: TypeError: a is null
</code></pre>
<p>I would like to receive the output '1' in this case.</p>

Recursive printing of a singly linked list homework
|
<p>I have an assignment in my java class that i need to recursively print out a linked list in reverse. I have looked online and found numerous examples of recursive methods that do this but take a node in as a parameter, and to my understanding i need to take in a linked list because i need to print the entire list out. Below is what code i have written, and it works in the sense that it prints out the list, recursively, but it is still in the same order that i created the list. After it prints out the list it throws a no such element exception as well. my main problem/question is wrapping my head around how best to print this recursively. </p>
<pre><code>public void printRecurse2(LinkedList<String> list2)
{
if(list2 == null)
return;
System.out.println(list2.pop());
printRecurse2(list2);
}

Return type vararg?
|
<p>I have a method like:</p>
<pre><code>void foo(int x, Grok... groks);
</code></pre>
<p>There's no way to define a method that returns a type of varargs, right? Ideally I want an additional util method:</p>
<pre><code>foo(25, new Grok(), new Grok(), generateMoreGroks());
public Grok... generateMoreGroks() {
return new Grok[] {
new Grok(), new Grok(), new Grok() };
}
</code></pre>
<p>right?</p>
<p>---- More info --------------</p>
<p>The issue with the above is that we can't mix a few Grok instances allocated there with an array of Groks:</p>
<pre><code> "new Grok(), new Grok(), generateMoreGroks());"
</code></pre>
<p>and I don't think that's legal, unless you could define a method to return a type of vararg (I guess).</p>

<pre><code>NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setFloat: self.viewController.sLabel.contentOffset.y forKey:@"floatKey"];
[prefs setObject:self.viewController.newText forKey:@"stringVal"];

<p>}</p>
<p>and to retrieve them, via a button, I do the following:</p>
<p>-(IBAction) riprendi:(id) sender {</p>
<pre><code>NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
float myFloat = [prefs floatForKey:@"floatKey"];
</code></pre>
<p>//some actions here</p>
<p>}</p>
<p>Everything is working on the simulator. However, using it on a real iPhone, the variables' saving and retrieving works just if you press the Home button, exiting the app and opening again but NOT if you switch off/on the iPhone. In this case, the variables get simply lost once you re-open the app...</p>

implementation of command line arg passing in python, doesn't work
|
<p>I'm very new to python. I wish I could implement the command-line arg passing in python as my first python script. I have written this code:</p>
<pre><code>def main(argv):
try:
opts, args = getopt.getopt(argv, "hb:b:f", ["help", "bucket=", "folder"])
except getopt.GetoptError:
usage()
sys.exit(2)
s3 = get_files()
for opt, arg in opts:
if opt in ("-h", "--help"):
usage()
sys.exit()
elif opt in ("-b", "--bucket"):
s3.bucketname = arg
elif opt in ("-f", "--folder"):
s3.foldername = arg
print("Came here" + s3.foldername)
s3.download_files()
</code></pre>
<p>In the <code>-f</code> argument from command is where I'm facing the problem. For debugging I used the <code>print</code> statement. I pass the arguments like this:</p>
<pre><code>./hello -b something -f /path
</code></pre>
<p>but sadly it prints out:</p>
<pre><code>Came here
</code></pre>
<p>But the <code>foldername</code> attribute is not getting assigned any value. Where I'm making the mistake?</p>
<p>Thanks in advance.</p>

<p>I have four lists</p>

<p>So basically every element (with every element)??
Now I know the very naive way to do this.

<p>The gist is that ScriptManager does not guarantee the order of execution and I have to run the <code>EndScript</code> function at the very end. It kinda works with the <code>setTimeOut</code> although it's not very accurate (since the JS on the pages differ)</p>

how to activate section Index Titles For Table View
|
<p>this is my first question here..</p>
<p>I have a tableview setting with numberOfSectionsInTableView=6, which has also custom created cells.
I am trying to use 'section index title' with some predefined titles . I have gone through sample code and following the same.
I'm able to show section index title from my tableview by using function 'sectionIndexTitlesForTableView'.
But to activate that, i don't know how to make it work when i clicked on some title. Let me want to move to the page based on title selection.
For example, same like how built-in Contacts(address book) works.</p>

Can't convert List<KeyValuePair<...,...>> to IEnumerable<object>?
|
<p>Getting an InvalidCastException when trying something like this :</p>
<pre><code>IEnumerable<object> test = (IEnumerable<object>)new List<KeyValuePair<string, int>>();
</code></pre>
<p>However, this did work:</p>
<pre><code>IEnumerable<object> test = (IEnumerable<object>)new List<Dictionary<string, int>>();
</code></pre>
<p>So what's the big difference? Why can a KeyValuePair not be converted to an object?</p>
<p><strong>Update</strong>: I should probably point out that this did work:</p>
<pre><code>object test = (object)KeyValuePair<string,string>;

Android ICS 4.0 OS
|
<p>I am a new Android developer starting out.</p>
<p>I hope that someone from the androids developers team can answer this question: if I have a tablet with android ICS 4.0 OS, given that this OS is UNIX-based, can I install the Android Developer Kit and related platform+ packages on it, so that I might study development on the go whilst traveling with my tablet?</p>
<p>I understand that one of the requisite OSes for the android development kit is UNIX - GNU C Library (<code>glibc</code>) 2.7 or later. Is ICS 4.0 compatible with this?</p>

PHP Assign a value to a var from IF statement variable

<p>I have something like this:</p>
<pre><code>$msg = '';
$var1 = 'image';
$var2 = 'class';
$var3 = 'This '.$var1.' has this class assigned:'.$var2;
if($E == 0) {
$msg = $var3;
} else {
$var1 = 'no image';
$var2 = 'no class';
$msg = $var3;
};
echo $msg;
</code></pre>
<p>I want to be able to show $var3 with the modified results but it does not work...
Thank you for your answers but i think i must clarify</p>
<p>Sorry about the confusion.. </p>
<p>The problem is not with the value to test ($E == 0).. My problem is that in both case the result will be the same and $var1 and $var2 will not change...</p>
<p>result in both cases will be the same:
echo $msg; will produce "This image has this class assigned: class "</p>
<p>I think is because of the composing of $var3 outside the if and cannot be changed from inside IF statement..</p>

Learning Java - importing and packages basics
|
<p>I'm reading every tutorial I can find as well as a book, still trivial concetps leave me asking questions:</p>
<ol>
<li><p><code>CLASSPATH</code> is a variable registered with the JVM that tells java the root directory in which to start looking for classes/jars/etc?</p></li>
<li><p><code>import</code> is similar to include (C/C++) but provides a namespace via package? I just read how without using import you have to explicitly state the package/namespace for every class (using the FQCN) such as java.util.String (possibly invalid excuse) where as using import java.util would allow me everywhere else in the code to simply refer to class as String.</p></li>
</ol>
<p>What confuses me about import is some examples use import like:</p>
<pre><code>import java.util.*; // import all public classes from java.util package
import java.util.Hashtable; // import only Hashtable class (not all classes in java.util package)
</code></pre>
<p>Yes the article also follows up:</p>
<p>Note that we can call public classes stored in the package level we do the import only. We can't use any classes that belong to the subpackage of the package we import. For example, if we import package <code>world</code>, we can use only the <code>HelloWorld</code> class, but not the <code>HelloMoon</code> class.</p>
<p>So which is it, when I use the * in an import is that not recursively importing all sub-packages?</p>

[UIImagePickerController availableMediaTypesForSourceType:picker.sourceType];
if (![sourceTypes containsObject:(NSString *)kUTTypeVideo ]){

Jquery sliding display built around moving a vertical stack of images

<p>How would I scroll a stack of images, horizontally, through a vertically aligned space? Imagine a layout like this:</p>
<p>I have a viewable area, say a div, with a fixed size (50px wide by 300px tall) and overflow set to none to hide anything outside of it...</p>
<p>That div has three images stacked vertically displayed inside it...</p>
<p>On click of a button I want to move those three images off to the left while moving in another set of three images from the right.</p>
<p>How do you do this? Should I create an unordered list for each set of three images and then move those UL's using javascript? This seems to make layout difficult. How would you approach this?</p>

Using LoaderManager without SimpleCursorAdapter
|
<p>I'm trying to update an app I wrote a year or so ago and upgrade all calls to deprecated code. In one place, I was using a SimpleCursorAdapter in a ListView, and I'd like to replace that with a proper LoaderManager, for several reasons.</p>
<p>The problem is, that all the examples I've been able to find of using a LoaderManager actually still use SimpleCursorAdapter, even though it's deprecated. This includes the official documentation. Can anyone point me to the correct way to do this? I'm willing to update my ListActivity to a ListFragment if needed, and do whatever else is required. I just can't figure out how to use LoaderManager without falling back on deprecated classes.</p>

<p>I know it should work, I have tried it on a laptop but I don't have access to it at the moment. I need to complete a homework so I tried the same on my PC. And when I type the same command into cmd it just runs pyscripter as if I would use right click on setup.py and click edit with pyscripter. It does nothing else. I am sure that I am in the right folder in cmd. </p>
<p>My python version is 2.7 and my pyscripter version is v2.5.3. My OS is win7. I have tried to install other modules but I get the same response. </p>
<p>Has anyone encountered the same problem? I have searched the internet but I haven't found any answers to this problem. </p>

Subtract & get difference of two images(touchpaint) and get an integer value in Android
|
<p>I have a requirement where the user needs to draw something on a FingerPaint like application and submits. I need to check to what extent the image matches and take the difference of the user's image with the ACTUAL image. The difference should then return an integer value. Depending on that, the user gets a score. Any suggestions is it possible to take difference of two images just like in MATLAB in Android?</p>

BufferedReader - read line by line

<p>I have created a buffered reader like this:</p>
<pre><code>this.inFile = new BufferedReader(new FileReader(fileName));
</code></pre>
<p>And then, I read from it like this</p>
<pre><code>while(System.currentTimeMillis() - lastRead < someTreshold) {
Thread.sleep(1)
}
lastRead += someTreshold;
String line = inFile.readLine();
//do something with line
</code></pre>
<p>Now I wanted to read a line with 20 entries like that, and display the results line by line. I hoped that I would get something like</p>
<pre><code>0
-someTreshold wait-
1
-someTreshold wait-
...
</code></pre>
<p>Wait I get instead is</p>
<pre><code>-someTreshold wait *20-
0
1

Replacing the variables in a file read by php
|
<p>I have a small app I am working on that generates configuration files. Because it may be used to generate a few different variants of configurations, I gather the variable values from the user, and then read in a template configuration from a file. That file has the names of the variables in it (i.e. $ip_address) at the proper positions. I have set those variables in my php code before reading and the printing out the files. However, the variable names are printed out, not the values of the variables:</p>
<pre><code>$hostname = $_POST['username'] . "_891";
$domain = $_POST['username'] . ".local";
$routerFile = "891.txt";
$file_handle = fopen($routerFile, "r");
while (!feof($file_handle)) {
$line = fgets($file_handle);
print $line . "<br />";
}
</code></pre>
<p>Output example:</p>
<blockquote>
<p><code>hostname $hostname</code><br>
<code>ip domain-name $domain</code></p>
</blockquote>
<p>How do I get php to replace the variables names with their stored values?</p>

Showing comments on same page, what is best tool to do that?

<p>I have a webpage on which people can comment about each topic. Problem is there are lets say 100 topics on the page. Each time user clicks on the topic he is redirected to new page. Where they can comment and start discussion. I want this to happen on same page. I thought about implementing colorbox, boxy and other things but they are too tacky and are just for few things not for lots of comments. Anybody out there have done this? Is there tool or better way to do this? </p>

send touch event from ADB to a device

<p>I am trying to send touch events to a device using ADB shell command, so that I can do some basic automation for UI tests. I have followed the discussion in some previous threads regarding this. </p>
<p>I confirmed about getting the events and using sendevents,to send out 6 events for each touch ( xcoord, ycoord, 2 for press,2 for release) and it was easy to use this information to sendevents, but a getevent for the touchscreen for a device seems to generate far too many events.</p>
<p>Has somebody managed to send touch event from ADB to a device? Could you please share the solution.</p>
<p>I really appreciate your help.</p>
<p>I am working on recording the touch events on phone. After that i wish to send the same event back to the device as part of UI testing.</p>
