|
<p>I'm trying to make a slot machine and im new to programming, so this will probably be a easy fix for people. </p>
<p>When i try this </p>
<pre><code>var money = document.getElementsByName('money')[0].value;
var bet = document.getElementsByName('bet$')[0].value;
var winnings = Number(bet) + Number(money);
$('#money').val(winnings);

Android applying border around SurfaceView
|
<p>I have one <code>SurfaceView</code> for which I want to display a border of <code>20dp</code> size which will flow around the <code>SurfaceView</code>. I need 'SurfaceView' in <code>16:9</code> aspect ratio, so i kept the size of the <code>SurfaceView</code> to <code>161x286</code> which is in <code>16:9</code> ratio. </p>
<p>To display border around the surface view i have following implementation in XML. </p>
<pre><code><RelativeLayout
android:id="@+id/my_surface_view_holder"
android:layout_height="161dp"
android:layout_width="286dp"
android:padding="20dp"
android:focusable="true"
android:clickable="true"
android:background="#fff"
>
<SurfaceView
android:id="@+id/video_surface_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
</code></pre>
<p>Above code displays the border around the <code>SurfaceView</code> properly but it breaks the 16:9 aspect ration of the video as i have given padding of <code>20dp</code> for displaying border.</p>
<p>If i adjust aspect ration according to the border size then border is not evenly set, on top/bottom it is different and on left/right it is different. </p>
<p>So How can i display the border around SurfaceView by keeping it's aspect ration maintained to size 161x286.</p>
<p>Thanks.</p>

How to getimagesize() after file_get_contents()?
|
<p>Unless I am mistaken, doing it the obvious way would download the file twice.</p>
<pre><code>$image = file_get_contents($location);
$checkImage = getimagesize($location);
</code></pre>
<p>I was wondering how I could do it without downloading twice. Placing <code>$image</code> inside <code>get_image_size()</code> doesn't work so I am not sure what to do. I found my tmp folder but when I ran the page to test I didn't see anything show up there so I'm not sure where to go with this. if I need to specify the actual location of <code>$image</code> (I think that is what I need to do) I am not sure how to find that.</p>

What is the simplest way to change the behavior of a method during runtime?
|
<p>I have class called <code>Enemy</code>, and I want to have multiple types of enemies. Each <code>Enemy</code> will have different movement behavior, for example one might move straight at the player, one might maintain a certain distance, etc. What I would like to know is, what is the simplest way to have multiple different behaviors, preferably in one class?</p>
<p>My current idea is to use a <code>switch</code>, and include all the behavior in one method</p>
<pre><code>public class Enemy
{
public int health;
public int damage;
// etc etc
public void Move(string type)
{
switch(type)
{
case "charge":
chargeMove();
break;
case "maintain":
maintainMove();
break;
}
}
private void chargeMove()
{
//stuff
}
private void maintainMove()
{
//stuff
}
//all the behaviors
}
</code></pre>
<p>What I would like to know, is it better to keep everything to one function like this, or to create a new class for each enemy type that inherits from <code>Enemy</code>? I would prefer to keep it to one class, so that all the enemies can be nicely stored into a <code>IList</code>, without me having to do any casting to use any of the specific functions.</p>
<p>Any advice would be appreciated.</p>
<p>EDIT: Thanks for all the responses, I think that I will use the interface method proposed by Alastair.</p>

Which way is better, setInterval() or window.setInterval()?
|
<p>Ok so there is a couple things to this question.</p>
<p>First of all, i'm asking this for setTimeout() and for setInterval()</p>
<p>I have seen a couple different ways to call them and i'm wondering which way is the best for this circumstance..</p>
<p>I'm making a js/canvas game and I'm just looking over my draw interval (where it loops the draw method)</p>
<p>Anyways, here are the different ways I have seen... </p>
<p><strong>Part A:</strong></p>
<ol>
<li><p>Using window.</p>
<pre><code>drawInterval = window.setInterval(draw, 60);
</code></pre></li>
<li><p>Not using window.</p>
<pre><code>drawInterval = setInterval(draw, 60);
</code></pre></li>
</ol>
<p><strong>Part B:</strong> </p>
<ol>
<li><p>Not using quotes and brackets around the function name</p>
<pre><code>drawInterval = setInterval(draw, 60);
</code></pre></li>
<li><p>Using quotes and brackets around the function name</p>
<pre><code>drawInterval = setInterval("draw()", 60);
</code></pre></li>
</ol>
<p>So for <strong>Part A:</strong> should i use window. or not?
And what about window.clearInterval() vs clearInterval by itself?</p>
<p>And for <strong>Part B:</strong> should I use quotes and brackets or not? I was told before that it was a bad idea to use quotes and brackets for this situation.</p>

Is it possible to programmatically detect the caret position within a <input type=text> element?
|
<p>Assuming a regular <code><input type=text></code> text-box with data in it. </p>
<p>Is it possible to detect (via JavaScript) the position of the text-coursor inside that text-box? </p>
<p>I am able to detect an ARROW LEFT or ARROW RIGHT keydown event - but how to detect the cursor location? </p>
<p><em><strong>Why I need this:</em></strong> </p>
<p>I have a dynamic text-box here: <a href="http://vidasp.net/tinydemos/dynamic-textbox.html" rel="nofollow">http://vidasp.net/tinydemos/dynamic-textbox.html</a><br>
It works great, however there are two scenarios that I would like to fix: </p>
<ol>
<li>when the cursor is at the beginning of the text-box and the user presses BACKSPACE </li>
<li>when the cursor is at the end of the text-box and the user presses DELETE </li>
</ol>
<p>(In both cases, the text-box must contain data for the effect to be observable.)</p>

How to make a list of numbers to calculate the arithmetic mean of the remainder?
|
<p>I have a project about java which wants me from to writing a console program that reads in a list of number scores on one line, separated by spaces, discards the highest and lowest numbers, then calculates the arithmetic mean of the remainder.</p>
<p>I have problems about how to make a array-list of number to calculate he arithmetic mean.</p>
<p>These are the codes : </p>
<p>Actually these codes are working in Java Applet and Java Application but I can take the numbers with scanner method but I couldn't find a solving way to make a list for the numbers.</p>
<pre><code>public static void main(String[] args) {
/*
* For data input.
*/
Scanner kb = new Scanner(System.in);
/*
* Declare an array to store the judge's scores.
*/
double[] scores = new double[8];
/*
* Declare variables for lowest and highest scores.
*/
double lowestScore = Integer.MAX_VALUE;
double highestScore = Integer.MIN_VALUE;
/*
* Read 7 judge's scores.
*/
for (int i = 0; i < 7; i++) {
System.out.println(String.format("Judge Score #%d: ", i + 1));
scores[i] = kb.nextDouble();
/*
* Compare the current score with the lowest and the highest scores.
*/
if (scores[i] < lowestScore) {
lowestScore = scores[i];
}
if (scores[i] > highestScore) {
highestScore = scores[i];
}
}
/*
* Sum the scores, except the lowest and the highest scores.
*/
double total = 0.00;
for (int i = 0; i < 7; i++) {
if (scores[i] != lowestScore && scores[i] != highestScore) {
total = total + scores[i];
}
}
/*
* Display the output.
*/
DecimalFormat df = new DecimalFormat("0.00");
System.out.println("Total points received: " + df.format(total));
System.out.println("Arithmetic Mean : " + df.format(total / 7));
}

Java application running slower and slower
|
<p>my Java code is running slower and slower when it is processing a large text file. I can observe that the output of my program is slowing because the increase of the output file is becoming slower. </p>
<p>I am afraid there is a memory leak somewhere. However, when I watch the memory usage through Windows Task Manager's Performance tag, I can see that the memory consumption stays quite stable, only minimal increase. Maybe Windows Task Manager doesn't show the memory leak?</p>
<p>the main logic is like this: read each line of text from the file, process it and store the result of the processing into a map </p>
<pre><code>Map<String, Integer> resultsPerLine = new HashMap<String, Integer>();
</code></pre>
<p>and then store a line number with resultsPerLine into another static map </p>
<pre><code>static Map<Integer, Map<String, Integer>> extractedResultMap
</code></pre>
<p>That's the main code.</p>

jquery - how to select for this, get a count, and get the current position within the selected group
|
<p>I have a set of img boxes that are marked up like this</p>
<p>I want to get a count and have this:</p>
<pre><code><div data-location-id="6" class="img-box-set">my img</div>
</code></pre>
<p>I have:</p>
<pre><code>var location_id = $(this).data('location-id');
// fixed per comment #1 below
var count_of=$('.img-box-set[data-location-id='+location_id+']').length;
alert("here is count_of" + count_of);
</code></pre>
<p>but the length always returns 0. Am I doing something wrong with selector or with length property?</p>
<p>Also, assuming I have 4, how would I determine which position I'm in (either 0-based or 1-based)?</p>
<p>thx</p>
<p><strong>edit #1</strong>
So I'd think this works but it isn't (per @jack ) and index docs. (update - this does work; had syntax error)</p>
<pre><code>var index_box=$('.img-box-set[data-location-id='+location_id+']').index(this);
alert("here is the index" + index_box);

Labelled break statement...where next
|
<p>I'm just doing the Sierra-Bates SCJP study guide and am wondering about the following question:</p>
<pre><code>public class Wind {
public static void main(String[] args) {
foreach:
for(int j=0; j<5; j++) {
for(int k=0; k< 3; k++) {
System.out.print(" " + j);
if(j==3 && k==1) break foreach; //1
if(j==0 || j==2) break;
}
}
}
}
</code></pre>
<p>When the value of k is equal to 1 and break foreach is executed (at line 1), where exactly does iteration go after this, to my mind does this now exit the whole loop. Where is the next point of iteration ? How is there any further iterations if the outside loop is exited ?
The answer given in the study book for this is 0111233. The way I see it, only 01 gets printed before the entire loop is exited. No ?</p>

Is it bad practice to nest 2 try catch statements in C#?

<p>Is the following code bad practice?</p>
<pre><code> try //Try Overall Operation
{
try //Try section 1 of operation
{
}
catch(exception ex)
{
//handle exception code
//throw the exception
}
catch (exception ex)
{
// send soap exception back to SOAP client.
}
</code></pre>
<p>I know from a program review point of view, other developers seeing 2 tries nested directly like that might wonder why, but is it totally taboo, or is it accepted practice now days?</p>
<p>Thanks Guys, I agree with you all about the refactoring, going to create a seperate method for the sub functionality, the method was getting really long. I am very impressed to all of you who picked this up...</p>

sequentially delayed fading in with jquery
|
<p>I have some array data returned from an ajax call consisting of an image link, some title text and a link. I am adding each element of this array to a div on the page by using the jQuery append method and the fading it in. Because it's executing so fast all the elements fade in at the same time. I'd like each one to fade in sequentially. So, when the element is added to the main div, fade in and then pause the .each statement for about 100 milliseconds before adding the next element. However I'm not sure how to do this. Any ideas? Here's my code.</p>
<pre><code>jQuery.each(data.themes, function (index){
theme_html = "<div class=\"themePreviewWrap\" id=\"theme_" + index + "\" style=\"display:none;\"><div class=\"themePreview\"><img src=\"" + data.themes[index]['custom_color_screenshot'] + "\" /></div><div class=\"themePreviewButtom\"><div class=\"title\"><b>" + data.themes[index]['title'] + "</b></div><div class=\"link\">" + data.themes[index]['actions'] + "</div></div></div></div>";

<pre><code>for deleted_partner in self.list_of_trading_partners:
B = A[:]
print("t", deleted_partner)
print(B[self.ID].list_of_trading_partners)
B[self.ID].list_of_trading_partners.remove(deleted_partner)
Round_neo_classic(B)
Round_costs(B)
if B[self.ID].final_good > reference_value:
print("d", deleted_partner)
print(A[self.ID].list_of_trading_partners)
A[self.ID].list_of_trading_partners.remove(deleted_partner)
</code></pre>
<p>Output:</p>
<pre><code>('t', 1)
[1, 2, 3, 4]
('d', 1)
[2, 3, 4]

Python string .format(*variable)

<p>I'm reading a book to read and it covers this below example.</p>
<pre><code>somelist = list(SPAM)
parts = somelist[0], somelist[-1], somelist[1:3]
'first={0}, last={1}, middle={2}'.format(*parts)
</code></pre>
<p>Everything seems clear apart from the star being used at the end of the last line. The book fails to explain the usage of this and I hate to progress on without full understanding things.</p>
<p>Many thanks for your help.</p>

C++ Abstract Base Class Problem
|
<p>So I have run into a problem with my ABC design in C++. I'm going to use a simplified example from what I actually have. Please ignore any syntax errors until I get to where my issue is.</p>
<p>So I have an ABC:</p>
<pre><code>class ABC
{
public:
virtual void DoSomething() = 0;
};
</code></pre>
<p>Then I have a derived class:</p>
<pre><code>class Derived: public ABC
{
public:
void DoSomething() { // something }
};
</code></pre>
<p>In my main logic function I have something along the lines of:</p>
<pre><code>ABC* obj = new Derived;
obj->DoSomething();
</code></pre>
<p>Now at this point my code works beautifully, I have multiple classes functioning correctly based on if I change the type (manually for now) from one derived class to another using the abstract base class as the type for the derived objects.</p>
<p>Now my issue...</p>
<p>If I want to change my derived class to add in functionality that is not supported by the ABC then my compiler is not recognizing them whatsoever. For example if I leave ABC the way it is and change Derived to:</p>
<pre><code>class Derived: public ABC
{
public:
void DoSomething() { // something }
void DoSomethingElse() { // something else, not defined in ABC}
};
</code></pre>
<p>Then back to my main logic function:</p>
<pre><code>ABC* obj = new Derived;
obj->DoSomething();
// Compiler does not recognize this, due to not being in the "ABC" class
obj->DoSomethingElse();
</code></pre>
<p>My compiler keeps giving me errors that "DoSomethingElse()" is not a member of the ABC. Is what I am trying to do possible? It feels like I am overlooking something simple but I've hit this road block in my architecture of this piece of software. Any help is greatly appreciated.</p>

jQuery monitor entire page?
|
<p>I have some code which adds a tooltip to all links. Now, the page keep changing with AJAX - how can I track these changes and add tooltips to links which are added to the document by AJAX?</p>
<p>I thought this might work:</p>
<pre><code>$(document).live('change', function(){
//code...
});
</code></pre>
<p>But I'm guessing there's a smarter/more efficient method to work this out. Any ideas? </p>
<p>Note: I can only use jQuery 1.3.2</p>

Screen auto rotates when unlocking
|
<p>Hi I am trying to save some values in my activity but I'm having a problem when I save it with onSaveInstanceState and restore with onRestoreInstanceState, I am saving an int years and it saves the first time the screen changes orientation, the spinner repopulates and sets it at the last value , but not when I switch back the orientation again.</p>
<p>My orientation is set to landscape in my manifest, and I have the two save and restore method overridden but it doesn't seem to work, do I need to do something in onPause aswell?</p>
<p>here is my code:</p>
<pre><code> int years;//global variable
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Spinner spinnerYears = (Spinner) findViewById(R.id.spinYears);//Spinner
final ArrayAdapter <Integer> adapter = new ArrayAdapter <Integer>(this,android.R.layout.simple_spinner_item );
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
for(int i=0;i<=100;i++)
{
adapter.add(i);
}
spinnerYears.setAdapter(adapter);
years = spinnerYears.getSelectedItemPosition();
}//onCreate
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putInt("MyInt", years);
}
@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
Spinner spinnerYears = (Spinner) findViewById(R.id.spinYears);//Spinner
final ArrayAdapter <Integer> adapter = new ArrayAdapter <Integer> (this, android.R.layout.simple_spinner_item );
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
for(int i=0;i<=100;i++)
{
adapter.add(i);
}
spinnerYears.setAdapter(adapter);
TextView tvYears = (TextView) findViewById(R.id.tvYears);//spinner Tv
tvYears.setVisibility(TextView.GONE);
int myInt = savedInstanceState.getInt("MyInt");
spinnerYears.setSelection(myInt);//

translate php website without extrernalizing resources
|
<p>I have a php site that mixes html and php.
ex: </p>
<pre><code><html>
hello <?=$username?>
</code></pre>
<p>I need infact to keep texts are they are. I do not want a classical solution such as that consits of creating reosurce strings and replace them such as: </p>
<pre><code><html>
<?=echo $helloString?> <?=$username?>
</code></pre>
<p>Infact a kind of "autoscript" that will replace all text resources at run time. So I keep the existing site and just add some script at begin.</p>
<pre><code><? include("translation_module.php?")?>
<html>
hello <?=$username?>
</code></pre>
<p>and this translation_module.php will replace "hello" to "bonjour".</p>
<p>Any clue to achieve that ?</p>
<p><strong>I don't care about grammer, currencies, plurial problems.</strong></p>
<ul>
<li>I guess it should work like google translate: it should execute itself, and translate then output texts and finally printout the result (of course I have no idea how it does it, how it handles $GET, $POST, $SESSION variables...)</li>
</ul>
<p>Thanks</p>

<p>This is as far as I got:</p>
<pre><code>$("#txtFilter").keyup(function () {

if () {
$(".tableStripe .tdName:not(:contains(" + text + "))").closest("tr").show();

determing the height in pixels of a gridview on an asp.net page at runtime?
|
<p>Anyone know if it possible at run-time to know how many pixels high an asp.net gridview is?</p>
<p>I have a gridview on the left of my page. On the right side, I populate with random images that vary in height and I would like to (as close as possible) match the total height of the gridview with the sum total heights of the pictures on the right. (The code keeps checking for pictures until it find ones with the right height).</p>
<p>I can approximate the height by knowing the number of rows (gridview.rows.count * an average row height), but since row heights can vary depending on if they are long lines wrapping, I'd prefer to try and get a better height estimate...</p>
<p>Thx!</p>

Can I create a function with the same name as the class?

<p>I want to create a function with the same name as its class using C#.</p>
<p>Sample Snippet:</p>
<pre><code>public class MyCustomer
{
public MyCustomer()
{
}
public void MyCustomer()
{
}
}
</code></pre>
<p>If I try to compile it visual studio is throwing an error.</p>

C# Static Classes & Scope
|
<p>I am just wondering why can't I define a static class as protected, private etc?</p>
<pre><code>protected static class Class1 {}
</code></pre>
<p>The compiler gives the following error message:</p>
<blockquote>
<p>Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal</p>

roaming detection in android
|
<p>I'm trying to detect when the roaming activation occurs. So far I've used the following piece of code, but because I haven't been able to test it I am unaware of it's correctness</p>
<pre><code>TelephonyManager telephonyManager = TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
PhoneStateListener cellLocationListener = new PhoneStateListener() {
public void onCellLocationChanged(CellLocation location) {
if(telephonyManager.isNetworkRoaming()
{
Toast.makeText(getApplicationContext(),"in roaming",Toast.LENGTH_LONG).show();
}
}
};
telephonyManager.listen(cellLocationListener, PhoneStateListener.LISTEN_CELL_LOCATION);
</code></pre>
<p>I've written this , thinking that in order for roaming to activate first the signal cell must change. Please let me know whether my deduction is correct or not, and if not how could I accomplish this.</p>
