Converting String to Int in Java using Arrays
|
<p>I'm trying to convert the string values to integers, however whenever i do this, it gives me the ASCI value of the character instead of the actual typed string. </p>
<p>Example: </p>
<p>a user inputs "11101" on there keyboard to a string variable named binary</p>
<pre><code>for(int i = 0; i < binary.length(); i++){
storage[i] = Integer.valueOf(binary.charAt(i));
}
</code></pre>
<p>if I look at the values of storage[i], i will see only the ASCI values of the numbers, and not the actual 1's or 0's</p>

Listview changes image on number of lines when i'm trying to update one line
|
<p>I have a list of items, which i'd like to "check" with filled star when user clicks on one item in the list.</p>
<p>I have a ListView with text & image, represented in XML layout, and using simple StringAdapter.</p>
<p>I've implemented the above by doing this:</p>
<pre><code> this.listViewSub.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(final AdapterView parent, final View view, final int position,
final long id) {
ImageView img = (ImageView) view.findViewById(R.id.unchkImg);
img.setImageResource(R.drawable.starchk);
</code></pre>
<p>I guess its not the right way to do it, but i don't have any idea how else to code it.
This code for some reason changes few random items in the list, and after one click i have about 4-5 items with icon changed.</p>
<p>Any idea how to solve it correctly?
Thanks</p>

horner data structure

<p>Hi
I have a question that how can we use Horner data structure for showing a polynomial which is like " <code>x^100+1</code>" ?</p>
<blockquote>
<p>for example for above polynomial we
need array of size 101 which its index
shows the power of this polynomial for
example for array[100]=1 and array[0]
= 1 and unfortunately all the other indexes are 0 !!! but there is another
way which is difference from this and
helps to show a polynomial in a little
array !!! and I want to know that way</p>

Is it possible to "symlink" a function in PHP easily - or alias the name to something else?

<p>For example, I hate typing things like:</p>
<pre><code>$x = mysql_escape_string(stripslashes($_GET['x']));
</code></pre>
<p>Is there a way to alias those two functions in init.php or something without writing a separate function that takes one argument and returns that argument with those functions applied to it?</p>
<p>My C/C++ is not very good, but I think this is sort of like #typedef but for functions?</p>

C++ char array gives strange output
|
<p>I am trying to create a char array in a function, pass it to main, and the print it out. This is giving me a string of random characters like this: ╠╠╠╠╠╠╠╠↑</p>
<p>Also, when I check the number of characters before the '\0' terminator the first output will give me the number of characters inputted, but the second output will give me 49 (size of the buffer), so I feel this is a problem involving the NULL terminator, but Im not sure how to resolve it. . </p>
<p>I have recreated the issue outside of my real project file, so the code is less messy and shown below. </p>
<pre><code>const int BUFFER = 50;
char* getWord()
{
char word[BUFFER];
cout << "Please enter a word: ";
cin.getline(word, BUFFER);
cout << "The word is: " << word; // This prints out the word with no problems..
return word;
}
int main()
{
char* wordPtr;
wordPtr = getWord();
cout << "Your word is: " << wordPtr << "\n"; // This prints out random symbols.
system("PAUSE");
return 0;
}
</code></pre>
<p>Any help is greatly appreciated.</p>

LinearLayout (horizontal) - Swapping button positions
|
<p>I have a horizontal <code>LinearLayout</code> which has 4 image buttons in it, all the same size with the same layout params. I would like the user to be able to swap the positions of buttons 2 and 3 over. I was thinking they could perhaps swipe over the buttons to swap them, or maybe have another small button between them with an arrow image that they pressed.</p>
<p>My problem is I'm not sure how I would swap the button positions over in the layout! I assume I need to get hold of the index of each in the layout and then add and remove them and then cause the layout to be recalculated so it is redrawn. Is this possible?</p>
<p>Also it would be nice to show some animation of the buttons moving in to position but I suspect this is just not possible.</p>
<p>Any advice?</p>

Calling a .php file
|
<p>I am what you call a developer with basic PHP scriptings, i have not yet developed complicated scripting so please bear with me.</p>
<p>I am working with a Pie Chart. This php script i found in the net creates a PNG File once it is called. </p>
<p>Example if you accessed it directly like .. </p>
<blockquote>
<p>www.url.com/generate.php</p>
</blockquote>
<p>This will create a generate.png Image of the Pie Chart</p>
<p>I want to pass values in to as to feed the SP to be used.</p>
<p>Example i like to use SP_contacts i would pass it like </p>
<blockquote>
<p>www.url.com/generate.php?foo='SP_contacts'</p>
</blockquote>
<p>it will then call the SP then after the query it will generate the Image.</p>
<p>then I would like to call the generated image and <strong>ECHO</strong> it in the <strong>HTML page</strong>.</p>
<p>i will have my <strong>Index.php</strong> page to handle the <strong>ECHO</strong>, now how will I call this <strong>generate.php</strong> inside my <strong>Index.php</strong></p>
<p>I am not sure how to make it work as I havent read any PHP Books or were trained to use PHP. I am just a go develop and learn guy and hopes that the internet is there for me. haha. Thanks in advance.</p>

javascript: pulse text using fade in and fade out?

<p>Hi i am trying to get a piece of text to fade in and out automatically without a click or hover method.</p>
<p>i'm not sure i can use an on page load function either because the text i want to fade in and out only appears after a user clicks to open another div on the page.? (I may be wrong?)</p>
<p>I am using this script but the text is static and not doing anything. Can anyone advise me where i'm going wrong? Thanks</p>

Creating own LiveWallpaperPreview?
|
<p>I would like to create my own LiveWallpaperPreview, i.e. to show the user a fullscreen preview of what the selected Live Wallpaper looks like (without the "Set Wallpaper" and "Settings" button that the stock-OS preview has).</p>
<p>Rebuilding the LivePicker-Class from 2.1 (<a href="http://android.git.kernel.org/?p=platform/packages/wallpapers/LivePicker.git;a=tree;f=src/com/android/wallpaper/livepicker;h=1557e0ae77aa8b0f8191472a204b5a7b4add31a4;hb=master" rel="nofollow">android.git.kernel.org</a>) works great, so I am able to let the user select a wallpaper to be previewed, but the actual LiveWallpaperPreview-Class tries to import the following private Interfaces/Classes:</p>
<p><code>import android.service.wallpaper.IWallpaperConnection;<br>
import android.service.wallpaper.IWallpaperService;<br>
import android.service.wallpaper.IWallpaperEngine;<br>
import android.service.wallpaper.WallpaperSettingsActivity;</code> </p>
<p>Is there any way to display a LiveWallpaper in my app without resorting to using the private APIs (which I obviously don't want to do)?</p>
<p>Thanks!</p>

C++ -- Why I can return an int for class Month
|
<p>Saw the following code snippet and I have problems to understand how it works.</p>
<pre><code>class Month {
public:
static const Month Jan() { return 1; }
...
static const Month Dec() { return 12; }
int asInt() const { return monthNumber; }
private:
Month(int number) : monthNumber(number) {}
const int monthNumber;
}
</code></pre>
<p>The class is designed in this way so that the user will not get invalid month value.</p>
<p>Here is the question:
why the static function Jan can return 1 with the return value as Month?</p>
<p>Thank you</p>
<p>Based on the comments, this class can be designed as follows:</p>
<pre><code>class Month {
public:
static const Month Jan() { return Month(1); }
...
static const Month Dec() { return Month(12); }
int asInt() const { return monthNumber; }
private:
explicit Month(int number) : monthNumber(number) {}
const int monthNumber;
};

how does a php application actually run?
|
<p>Fairly new to web-programming and programming in genral.</p>
<p>In c/c++, the code is all compiled into an exe and run once. The user(s) interact with it and according decisions made by the compiled code that is running, it outputs relevant information.</p>
<p>But in web(php), the users cannot point and click or use keyboard directly to interact with the software (eg. drupal). They can only send it texts of strings (through POST etc) to which the software generates an output and sends it back.</p>
<p>Questions: How does this interpreted(php) software run on the server? How does it function with Apache? Is index.php in drupal equivalent to a .exe produced by c/c++ which runs everytime a request is made by user?</p>

JQuery . after not working on class added via JQuery
|
<p>This question is in relation to a question I posted yesterday. The link -http://stackoverflow.com/questions/12636348/how-to-add-a-different-class-to-the-same-class-in-jquery . The question and problem now is that I will like to have a div added after the div with the class being added. The problem is the script that I'm using adds the div only to an existing/default class name and not the added class via JQuery. The script is below.</p>
<pre><code> $(document).ready(function(){$('.example').each(function(i){$(this).addClass("ex" + i);});
$('.ex0').after(function(){return'<div class="afterdiv"><a class="afterdiva1" href="#" title="Text."></a><a class="afterdiva2" href="#" title="Text."></a></div>'});
</code></pre>
<p>The default output is:</p>
<pre><code> <div class="example"></div>
</code></pre>
<p>The final html output should read as:</p>
<pre><code> <div class="example ex0"></div>
<div class="afterdiv">
<a class="afterdiva1"></a>
<a class="afterdiva2"></a>
</div>
</code></pre>
<p>Update- I apologize for not clarifying that each div needs to be unique to/per class. Sincere apologies (I'm new to asking for help here or anywhere else for that matter). </p>

<p>I understand that .live() works in attaching events for elements created in the future, but will attach events multiple times like .bind() does. But I need to attach the event only once.</p>

<p>For my case</p>
<p><a href="http://jsfiddle.net/ppTqp/1/" rel="nofollow">http://jsfiddle.net/ppTqp/1/</a> -> Should alert "Live from test" only once. With .live method it alerts twice.</p>

List Mutation on Python
|
<p>I tried mutating a list by swapping a common element between the list and another reference list with the first element. The implementation is as shown below: </p>
<pre><code>>>> L = [1,2,3,4,5,6,7,8,9]
>>> A = [3]
>>> L[0], L[L.index(A[0])] = L[L.index(A[0])], L[0] #want to swap 3 with 1
>>> L
[1,2,3,4,5,6,7,8,9,] #List L was not mutated
</code></pre>
<p>The list was not mutated as I anticipated. But when I modify the implementation as shown below, it worked: </p>
<pre><code>>>> L = [1,2,3,4,5,6,7,8,9]
>>> A = [3]
>>> i = L.index(A[0])
>>> L[0], L[i] = L[i], L[0]
>>> L
[3,2,1,4,5,6,7,8,9,] #Now list mutated as desired even though L[i] and L[L.index(A[0])] evaluate to same value.
</code></pre>
<p>My question is, why couldn't the first assignment mutate the list? I thought of it but my brain coudnt explain it.</p>

jquery timeago plugin and jquery corner plugin don't work with dynamic content
|
<p>I have a list of reviews, and when you add a review it posts to a PHP page and then loads a Smarty template into the beginning of the review list to show the review you just posted.</p>
<p>That works fine. However, I use a rounded corners plugin and timeago on the review post. I tried re-calling these functions after it loads the review, but that doesn't work either.</p>
<p>I am aware that using .live is approprite for fixing this problem in many other cases, but I don't know how I could apply that here. jquery's .live only works on events. What is the event here?</p>
<p>Any ideas?</p>
<p>For reference: jquery timeago plugin: <a href="http://timeago.yarp.com/" rel="nofollow">http://timeago.yarp.com/</a>
jquery corner plugin: <a href="http://www.methvin.com/jquery/jq-corner-demo.html" rel="nofollow">http://www.methvin.com/jquery/jq-corner-demo.html</a></p>
<p>--</p>
<p>As requested, here is some elaboration: I use $.load to load the template content into the div area. There are no errors from this. It works perfectly, with the exception of the timeago/corner plugins not affecting the output.</p>
<p>I don't have the code accessible to me right now, but it goes a little something like this:</p>
<pre><code>$.load('/inc/templateLoader.php?tpl=reviews');
$('abbr.timeago').timeago();
$('.corner').corner();
</code></pre>
<p>Some people have suggested it might not be working because $.load can complete before the page loads, which would cause the issue I am experiencing.</p>

FilterQueryProvider not updating ListView
|
<p>Trying to use the FilterQueryProvider function to update the contents of a ListView, as characters are entered into the filter, my runQuery function does get called, and a new cursor with filtered content is returned, but the ListView does not update to show the new contents. The docs state that after runQuery returns, changeCursor is called. Isn't this enough to update the ListView display? My code to set up the filter is:</p>
<pre><code> mAdapter = new ItemAdapter(curs);
mAdapter.setFilterQueryProvider(new ItemFilter());
setListAdapter(mAdapter);
</code></pre>
<p>And my filter class is simply:</p>
<pre><code>class ItemFilter implements FilterQueryProvider {
public Cursor runQuery(CharSequence filter) {
return getNewCursor(filter);
}
}
</code></pre>
<p>The cursor from getNewCursor does correctly fetch a subset of the rows. Have I missed something in getting the ListView to update?</p>

ASP.net Using a Session Varriable to move a GridView SelectedDataKey to another page
|
<p>Help please!</p>
<p>I am pulling out what little hair I have left over this and can't find an answer.</p>
<p>I am attempting to move the selected row in a grid view to another page and use the SelectedDataKey or the primary key value of the selected row to indicate what data should be displayed in a grid view on another page. This is the last little bit of a school project that I can't figure out.</p>
<p>What I am doing on the first page is to use a button click event to set a session variable that looks something like this. Session["Select"] = GridView1.SelectedDataKey; The button will then send the user to the next page. Response.Redirect("CustomerAccounts.aspx");</p>
<p>Once on the next page I want to use the primary key selected on the first page to show only the data with a coresponding value on the second page by using a where statement in the next gridview. So I am setting the [CustomerID]=? Session("Session["Select"])</p>
<p>Am I setting up the where correctly in the second gridview? </p>

<p>I'm trying to echo the variable <code>$theurl</code> inside of <code>$image_all</code> but it's not working.</p>
<pre><code>$theurl = OF_DIRECTORY;
$image_all = $theurl.$image_path;
</code></pre>
<p>This should be simple, right? It's only showing what <code>$image_path</code> equals, even though it will echo <code>$theurl</code> if I simply do <code><?php echo $theurl; ?></code>.</p>
<p>What am I missing?</p>

IntPtr to String and long?
|
<p>i use c#.net 2.</p>
<p>I have this method here to get a string out of a IntPtr:</p>
<pre><code> void* cfstring = __CFStringMakeConstantString(StringToCString(name));
IntPtr result = AMDeviceCopyValue_Int(device, unknown, cfstring);
if (result != IntPtr.Zero)
{
byte length = Marshal.ReadByte(result, 8);
if (length > 0)
{
string s = Marshal.PtrToStringAnsi(new IntPtr(result.ToInt64() + 9L), length);
return s;
}
}
return String.Empty;
</code></pre>
<p>It works an all data which is saved as string in my USB-Device (return data of method "AMDeviceCopyValue").</p>
<p>Now I get this:
"£\rº\0\0¨\t\0\0\0ˆ\0\0\0\0\0\0x>Ô\0\0\0\0Ũ\t\0\0\0€1ÔxÕ͸MÔ\0\0\0\0Ȩ\t\0\0\0€)\0fŒ\a\0Value\0\0˨\t\0\0\0€7fŒ\a\0Result\0Ψ\t\0\0\0ˆTÅfŒ\a\0\0Key\0\0\0\0ñ¨\t\0\0\0€+fŒ\a\0Port\0\0\0ô¨\t\0\0\0€%fŒ\a\0Key\0\0\0\0÷¨\t\0\0\0€:\0\0\0\0\0\0\0\0\0\0\0\0\0\0ú¨\t\0""</p>
<p>This is saved as "long" - so, how I can get this IntPtr into long and not string?</p>

regarding jquery animate and opacity
|
<p>here is my code by which i am showing my div & hiding my div with grow & shrink effect. i want that when div is going to shrink then div will be fadeout before it's size is zero.
according to my code my div is fadeout when div size is 0. i mean when height & width is zero.</p>
<p>so please go through my code and tell me how can i fadeout my div before it size become zero.
suppose my div size is 300px. when height & width decrease to 150px with the help of animate function then i want that my div will be fadeout completely. so tell me what to change in my code.</p>
<p>next i saw if i click repeatedly on "click here" button then some flicker occur and also i saw div stuck for one sec or less than one sec. why it happen. how to improve the effect.
what to change in the code. here i am giving my code. please test it and if possible make it more smoother.</p>
<pre><code><div class="click">Click here</div>
<div class="grower"></div>
.click {background:#ccc; border:1px solid black; padding:10px; display:inline-block}
.grower {width:0; height:0; background:red; position:absolute; top:150px; left:150px;opacity: 0}
var grower = $('.grower');
var flag=0;
$('.click').click(function(){
var windowWidth = $(window).width();
var windowHeight = $(window).height();
var left = windowWidth/2 - 150;
var top = windowHeight/2 - 150;
if(flag==0)
{
grower.css({left:windowWidth/2, top:windowHeight/2});
grower.animate({opacity : 1,width:300, height:200, left:left, top:top},'slow');
flag=1;
}
else if(flag==1)
{
grower.animate({opacity : 0,width:0, height:0, left:(windowWidth/2 - $('#grower').width()), top:(windowHeight/2 - $('#grower').height())},'slow');
flag=0;
}

Python: nearest neighbour (or closest match) filtering on data records (list of tuples)
|
<p>I am trying to write a function that will filter a list of tuples (mimicing an in-memory database), using a "nearest neighbour" or "nearest match" type algorithim.</p>
<p>I want to know the best (i.e. most Pythonic) way to go about doing this. The sample code below hopefully illustrates what I am trying to do.</p>
<pre><code>datarows = [(10,2.0,3.4,100),
(11,2.0,5.4,120),
(17,12.9,42,123)]
filter_record = (9,1.9,2.9,99) # record that we are seeking to retrieve from 'database' (or nearest match)
weights = (1,1,1,1) # weights to approportion to each field in the filter
def get_nearest_neighbour(data, criteria, weights):
for each row in data:
# calculate 'distance metric' (e.g. simple differencing) and multiply by relevant weight
# determine the row which was either an exact match or was 'least dissimilar'
# return the match (or nearest match)
pass
if __name__ == '__main__':
result = get_nearest_neighbour(datarow, filter_record, weights)
print result
</code></pre>
<p>For the snippet above, the output should be:</p>
<p><strong>(10,2.0,3.4,100)</strong></p>
<p>since it is the 'nearest' to the sample data passed to the function get_nearest_neighbour().</p>
<p>My question then is, what is the best way to implement <strong>get_nearest_neighbour()</strong>?. For the purpose of brevity etc, assume that we are only dealing with numeric values, and that the 'distance metric' we use is simply an arithmentic subtraction of the input data from the current row.</p>

for loops in object within object
|
<p>Can someone explain why doesn't this work?</p>
<p>I have two objects within an object. I use for loops to print out each property within the nested objects, one after another.</p>
<pre><code>var people = {
john: {
name: "John",
age: 20
},
bob: {
name: "Bob",
age: 40
}
};
for (var person in people) {
for (var property in person) {
console.log(property);
}
}
</code></pre>
<p>I expect it to print out:</p>
<pre><code>name
age
name
age
</code></pre>
<p>Instead I get:</p>
<pre><code>0
1
2
3
0
1
2
</code></pre>
<p>1) What am I doing wrong?</p>
<p>2) What exactly is the console doing to output the numbers above?</p>

<p>The only way I know to make sure to cast the <code>regex</code> to a safe <code>Object</code> type, is to use <code>eval()</code>. </p>

Javascript 'delete' doesn't work inside iteration loop
|
<p>I'm a C/C++/Java programmer working with JavaScript.</p>
<p>I'm trying to write a function that will delete all properties of an object 'obj'. I've read the posting on "<a href="http://stackoverflow.com/questions/684575/how-to-quickly-clear-a-javascript-object">How to quickly clear a Javascript Object?</a>" and saw that there are two answers: (1) creating a new 'obj' (which I don't want to do because my code is a high-performance program running in a mobile browser, and I want to minimize garbage collection); and (2) iterating over the properties of an object in a loop and deleting the properties. This latter approach doesn't work in Chrome 12.</p>
<p>Consider the following code:</p>
<pre><code>var foo = {};
foo['baz'] = 'bar';
console.log("1. foo.baz = " + foo.baz);
delete foo.baz;
console.log("2. foo.baz = " + foo.baz);
foo['baz'] = 'bar';
console.log("3. foo.baz = " + foo.baz);
for (prop in foo)
{
if (foo.hasOwnProperty(prop))
{
console.log("deleting property " + prop);
delete foo.prop;
}
}
console.log("4. foo.baz = " + foo.baz);
</code></pre>
<p>This produces the following result in my console on Chrome 12:</p>
<pre><code>1. foo.baz = bar
2. foo.baz = undefined
3. foo.baz = bar
deleting property baz
4. foo.baz = bar
</code></pre>
<p>Why doesn't foo.baz get deleted inside the loop?</p>

<p>I have a select box, which i can populate using two methods.</p>
<p>First - Just by selecting any one of the option in the select box.</p>
<p>Second - I have a link just beside the select box.Clicking this link takes me to a page2, which has the same options but as links in page2.When i click one of them , it populates the select box.</p>
<p>Selecting the option directly from the "select" triggers an onchange event in it.
But when i click the link, select my required option from that page, it does not trigger the onchange event in the select box.
I am not sure where i am doing a mistake.</p>

what is the best way of sharing a configuration object across classes?

<p>Let us say that I have the classes M, A, B, C. M is the main class of my application (that is the one that does most of the job) and has this structure</p>
<pre><code>class M {
public:
// Something here.
private:
Conifg config;
A a;
std::vector<B> bs;
const C* c;
};
</code></pre>
<p>In a main I create an instance m of class M and I want to set my config object, say by reading it from a file. The configuration object is nothing special, it could be a protocol buffer or a simple struct.</p>
<p>Now, I want a, b and c to be able to access the config object, because there are some global settings that they need. These settings are global, they do not change, and are the same for each instance of A, B and C (and M). What I am currently doing, is having a static field in each class A, B and C and I am setting a copy of the configuration object for each instance of these classes. I do not want these classes to know of the existence of M. Is this the best solution? Should I perhaps think of a global config variable?</p>
