Magic 8 ball - text verification if almost the same?
|
<p>I'm building a fun kind of 8 ball website in <strong>PHP</strong> where people ask questions and get a yes or no answer.</p>
<p>I'm looking to avoid the obvious mistakes like repeated questions...
but I was hoping there was also a way of doing it to check if it almost the same. For example, if someone typed the following questions one after the other into the program, it should be able to give the same answer:</p>
<pre><code>Will I be rich this year?
Will I be rich?
Will I be rich
</code></pre>
<p>Is this possible? I fault of the Eigen... thing, but not too familiar and these seem more complex than the usual.</p>
<p>Any help much appreciated.</p>

Launch popup window from service

<p>I need to launch a popup window from a service to do something specific inside my application. I do not seem to find a good way to do it. Inside onCreate() I create the popup window but when I launch it with showAtLocation I get this error:</p>
<pre><code>10-06 13:39:49.573: ERROR/AndroidRuntime(5966): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?
</code></pre>

Does checking against null for 'success' count as "Double use of variables"?
|
<p>I have read that a variable should never do more than one thing. Overloading a variable to do more than one thing is bad. </p>
<p>Because of that I end up writing code like this: (With the <code>customerFound</code> variable)</p>
<pre><code>bool customerFound = false;
Customer foundCustomer = null;
if (currentCustomer.IsLoaded)
{
if (customerIDToFind = currentCustomer.ID)
{
foundCustomer = currentCustomer;
customerFound = true;
}
}
else
{
foreach (Customer customer in allCustomers)
{
if (customerIDToFind = customer.ID)
{
foundCustomer = customer;
customerFound = true;
}
}
}
if (customerFound)
{
// Do something
}
</code></pre>
<p>But deep down inside, I sometimes want to write my code like this: (Without the <code>customerFound</code> variable)</p>
<pre><code>Customer foundCustomer = null;
if (currentCustomer.IsLoaded)
{
if (customerIDToFind = currentCustomer.ID)
{
foundCustomer = currentCustomer;
}
}
else
{
foreach (Customer customer in allCustomers)
{
if (customerIDToFind = customer.ID)
{
foundCustomer = customer;
}
}
}
if (foundCustomer != null)
{
// Do something
}
</code></pre>

<pre><code>pad_zero(Decimal('10.0'))

<p>*<em>EDIT:</em>*format method does not fit my need because I need to pass it on as decimal, I understand though, that i can convert it back to afterwards, but such to-and-fro seems somewhat unpythonic.</p>

Get a file from a Database and put it in an ftp
|
<p>Hello I have an aspx page that gets a list of documents available in a database through a DataGridview and I want that when the users clicks on the link of the document he want's to sent it as an ftp or http document, like if it was on a drive on the server. </p>
<p>The problema I have is that I know that when the file is on a drive it is easy but if it is on the database I do not know how to serve it to the web page user. </p>
<p>I thougth maybe that when de user clicks on the link to save the file to a temp directory, and then redirect the page to that page with the name of the file, but I do not know if it is to much of a touble and there is a better way. Of course if I do this I will have to delete the file from the drive after it has been downloaded.</p>
<p>Thanks for any comments.</p>

Clarification about the order of variables used in a function
|
<p>I've been fighting with this PHP-snippet for some hours and I can't figure it out...<br>
How does PHP determines the order when to pass the variables in this snippet:</p>
<pre><code>function myfunction ($left, $right) {
echo $left;
echo '<br>';
echo $right;
}
$a = array ('one', 'two', 'three', 'four');
usort($a, 'myfunction');
</code></pre>
<p>In this case, the variables are passed like this:</p>
<pre><code>$left = 'two' - $right = 'one';
$left = 'four' - $right = 'two';
$left = 'three' - $right = 'two';
$left = 'four' - $right = 'three';
</code></pre>
<p>But how is this sequence determined?!? I've been cracking my head and couldn't find any logic... </p>

how to get the most common character in an array?
|
<p>Suppose I have an integer array like this:
{5,3,5,4,2}</p>
<p>and I have a method which returns the most common character </p>
<pre><code>public int highestnumber(String[] num) {
int current_number = Integer.parseInt(num[0]);
int counter = 0;
for (int i = 1; i < num.length; ++i) {
if (current_number == Integer.parseInt(num[i])) {
++counter;
} else if (counter == 0) {
current_number = Integer.parseInt(num[i]);
++counter;
} else {
--counter;
}
}
return current_number;
}
</code></pre>
<p>but if I have multiple common character then i need to get the number which is closest to one(1), like if i have an array like this:
{5,5,4,4,2};</p>
<p>then the method should return 4, what should I do for this?</p>

JavaScript tree / treegrid libraries
|
<p>I'm looking for a good JavaScript tree / treegrid package. Now -- before you answer:</p>
<p>It needs to be able to perform well with <em>lots</em> of nodes. Perhaps 1,000 sibling nodes. It needs to be able to draw to a usable state within 2 or 3 seconds with 1,000 nodes. It doesn't necessarily need to draw all 1,000 nodes at once -- if it supports some sort of "smart rendering" or fake scrolling.</p>
<p>Beyond that, column resizing, drag and drop, inline editing would all be nice, although I could probably add that functionality myself. </p>
<p>I've already tried dojo's tree and yahoo's YUI treeview. Both are too slow.</p>

When we mouseouver the input box, it will display the title, but i just want this to happen when I click on the input box.</p>
<p>My idea is displaying a title saying "value copied", cause I have a function on "onclick" event that copy the input (read only) value to the clipboard, and when it's done I want to let the user know that this happen displaying that information.
Is that even possible?

<p>I've got field in my database which contain strings like <code>21;48;33;22;31</code>. Then I'd like to convert it to mathematical calculation <code>21+48+33+22+31</code>.</p>
<pre><code>$points = "21;48;33;22;31";
$points = str_replace(";","+",$points );
$points = preg_replace('/[^0-9\+\-\*\/\s]+/', '', $points);
echo $points;
</code></pre>
<p>But that simply does not work. I've got the same string "21+48+33+22+31" instead of the sum.</p>

Want android app to wait until user presses a button before continuing
|
<p>I have a game for android, and when the user wins, it shows a dialog asking if they want to play again. If they say "no", the application exits, and if they say "yes", it starts another game. The problem is that a new game starts as the dialog is displayed, instead of waiting for the user to press a button. The code is like this:</p>
<pre><code>if (won) {
showDialog(DIALOG_WON_ID);
imageAdapter.initializemThumbIds(); // this starts a new game
}
</code></pre>
<p>I don't want the start-new-game line to execute until the dialog is dismissed.</p>

} else {
throw new Exception('unable to look up the county');

</code></pre>
<p>I tried </p>
<pre><code>if($result)
if($result != null)
if($result != '')
if(!empty($result))
if(isset($result))
</code></pre>
<p>neither one worked, script always goes inside the block, but the value of $result is null, I can see it through xdebug.
Why is this happening?</p>
<p>edit:
here's a screenshot

<p>here's what var_dump shows:</p>

Access local variable in function from module
|
<p>I have a function in my main program that attempts to retrieve information from an imported module, which is a different script I wrote. This module spits out a variable which I access from the main program by making it a global.</p>
<p>However, since I'm threading the function that requests the information, the global variable gets polluted by adding the information from separate requests into one var. What I'm looking for is a way to access a local variable in a function in a module.</p>
<p>Main program:</p>
<pre><code>import module
def threaded_function():
module.function(var1, var2)
print module.output
</code></pre>
<p>Module:</p>
<pre><code>def function(var1, var2):
global output
output = []
DoThingsWithVars(var1, var2)
output.append(result)
</code></pre>
<p>Since the threading causes it to get accessed multiple times I figured I'd not use global variables and get the local variables for each request. Any idea how I can get at those?</p>

In Python, how can I open a file and read it on one line, and still be able to close the file afterwards?
|
<p>While working through this exercise I ran into a problem.</p>
<pre><code>from sys import argv
from os.path import exists
script, from_file, to_file = argv
print "Copying from %s to %s" % (from_file, to_file)
# we could do these two on one line too, how?
input = open(from_file)
indata = input.read()
print "The input file is %d bytes long" % len(indata)
print "Does the output file exist? %r" % exists(to_file)
print "Ready, hit RETURN to continue, CTRL-C to abort."
raw_input()
output = open(to_file, 'w')
output.write(indata)
print "Alright, all done."
output.close()
input.close()
</code></pre>
<p>The line <code># we could do these two on one line too, how?</code> is what’s confusing me. The only answer I could come up with was:</p>
<pre><code>indata = open(from_file).read()
</code></pre>
<p>This performed the way I wanted to, but it requires me to remove:</p>
<pre><code>input.close()
</code></pre>
<p>as the input variable no longer exists. How then, can I perform this close operation?</p>
<p>How would you solve this?</p>

C# Windows Form with Attached Windows Service

<p>I know how I can create a Windows Service in C# but I have a series of variables that the user currently feeds into a text file and I wanted to control this process. So can I attach a Windows service to a Windows form application to control such things as installing the service, uninstalling the service, start and restart. Or is it better to have them completely separate and just use the form app to run system commands for install/uninstall and use the serviceController to start/restart?</p>

How to set class names dynamically?

class NewClass(BaseClass) : pass
return NewClass

<p>Now when I use it to create new classes, the classes are all named the same, and the instances look like they have the same type:</p>
<pre><code>NewA = factory(ClassA)
NewB = factory(ClassB)
print type(NewA()) # <class __main__.NewClass>
print type(NewB()) # <class __main__.NewClass>

How to access a password protected url with special character(backslash) in Java?
|
<p>I'm trying to access a file on a server which is password protected which I've tried setting up a Password Authenticator to handle. However the username has a '\' character right in the middle of it. "foo\bar" which gives an error.
I just can't figure out how to encode the username.
I've tried the following: "foo\bar", "foo%5cbar", and "foo%92bar"</p>
<p>I'm hoping the problem is that I haven't encoded the name correctly, but it might be aproblem with my code. Any help is appreciated.</p>

Using same XIB for new/edit action
|
<p>I am making an app which among other things has the oppertunity to add new items or edit(show) existing ones by tapping a row in the tableview. The "detailed" view will be the exactly the same on both actions however with the edit(show) view will ofcourse be in the state of whatever the user has chosen. So my question is, is it bad to use the same XIB for these two viewcontrollers? Or should I make the same view twice?</p>

Illegal forward Reference java issue
|
<p>Could anyone explain what is wrong with this code:</p>
<pre><code> public class Base {
static {
i = 1;
System.out.println("[Base]after static init block i=" + i);// LINE 1
System.out.println("*************************************");
System.out.println();
}
static int i;
public static void main(String[] args) {
System.out.println(Base.i);
}
}
</code></pre>
<p>If I comment LINE 1 - everything is OK and Base.main method prints "1".
If LINE 1 - is not commented, got compile time error: "illegal forward reference".
So, as i understand in static init block I can set value for i, but not read. Could anyone explain why?</p>

Some problems for Android SDK tool revision 7
|
<p>Updated Android SDK tools 7 (for Eclipse, windows 7 32 bits). But I
got some problems:</p>
<ol>
<li>Android looks changed some package name, For example, the
"android.intent…"was changed to “android.content.intent…”; the
“android.permission…” was changed to “android.Manifest.permission…”.
If I change the old package name to the new one, the emulator will not
work for the application.</li>
<li>The tools 7 replaceed some drop-down list selection to Browser
selection, for example, the IntentFilter Attributes selection and
permission attributes selection no longer have drop-down list
selection instead of a “Browser”.</li>
</ol>

Game Randomly Freezes Up and Won't Repaint
|
<p>I am working on a game at the moment. Whenever I go into Level 1, exactly 1500 milliseconds into the level, it freezes and I can't close out of it (I have to kill the process). I have a loop which repeatedly calls <code>repaint()</code> and a <code>System.out.println("Repainting")</code> line above it. I also have a <code>System.out.println("Paint component called")</code> line in the <code>paintComponent()</code> method. When it freezes, it keeps printing "Repainting" but won't print "Paint component called".</p>

Differences between .text() and .html() with escaped < and > characters
|
<p>Given the following HTML fragment:</p>
<pre><code><p id="para">hello &lt;world&gt;</p>
</code></pre>
<p>The jQuery <a href="http://api.jquery.com/text/" rel="nofollow"><code>.text()</code></a> and <a href="http://api.jquery.com/html/" rel="nofollow"><code>.html()</code></a> methods will return different values...</p>
<pre><code>var text = $('#para').text(); // gives 'hello <world>'
var html = $('#para').html(); // gives 'hello &lt;world&gt;'
</code></pre>
<p>The jQuery documentation states</p>
<blockquote>
<p>The result of the <code>.text()</code> method is a string containing the combined text of all matched elements.</p>
</blockquote>
<p>and...</p>
<blockquote>
<p>In an HTML document, we can use <code>.html()</code> to get the contents of any element. If the selector expression matches more than one element, only the first one's HTML content is returned.</p>
</blockquote>
<p>But this specific difference with <code>&lt;</code> and <code>&gt;</code> doesn't seem to be documented anywhere.</p>
<p>Can anyone comment on the rationale for this difference?</p>
<h2>Edit</h2>
<p>A little more investigation suggests that the values <code>.text()</code> and <code>.html()</code> match those from the native JavaScript <code>innerText</code> and <code>innerHTML</code> calls respectively (when the jQuery selector has returned a single element, at least). Again, this is not reflected in the jQuery documentation so I am not 100% sure if this observation holds true in all scenarios. Reading through the <a href="http://code.jquery.com/jquery-1.4.4.js" rel="nofollow">jQuery source</a> reveals that this isn't what's actually going on under the hood.</p>

Mechanism in Java compiler to substitute method name as literal string
|
<p>Is there a keyword (or equivalent) in Java that the compiler substitues with the name of the method (and/or class, etc) that the keyword appears in? This would be similar to the</p>
<pre><code>__FUNCTION__
</code></pre>
<p>macro is C/C++.</p>
<p>I know Java "doesn't support macros", but I'm not asking for user #define'able macros, just a small set of keywords that are replaced with literal strings that the compiler knows.</p>
<p>I know there are methods to get the method a piece of code appears in (<a href="http://www.rgagnon.com/javadetails/java-0420.html" rel="nofollow">http://www.rgagnon.com/javadetails/java-0420.html</a>) but I'm assuming these are not cost-free. Not surprisingly, if this functionality exists I'd like to use it in tracing, so it really does need to have zero cost or very close to it.</p>
<p>I guess this would be up to the compiler implementation, so maybe my question is whether the usual Java compilers (whatever comes with the JDK) support this.</p>
<p>If not, I fail to understand why this isn't available since it seems useful and I assume it would be trivial for the compiler to provide since surely it knows the method name of the code it's compiling.</p>

text = text.replace(text,"$\'");
console.log(text);

<p>This prints an empty string to the console. I was expecting it to print $' to the console. Can anyone explain this? </p>

Fade in divs by passing two id's in query
|
<p>I'm trying to create a row of divs with hidden images inside, when moused over the middot will fade out, image will fade in, then fade out when the mouse leaves that div. I know I need to do something with the .hover function in jquery.</p>
<p>For example</p>
<pre><code><div id='1_1'>
&midddot;
<img src='image1_1.jpg' style='display:none'>
</div>
<div id='1_2'>
&midddot;
<img src='image1_2.jpg' style='display:none'>
</div>
<div id='1_3>
&midddot;
<img src='image1_3.jpg' style='display:none'>
</div>
</code></pre>
<p>Each div will represent a page of an article. So where id='1_3', that'd be a row 1, page 3, or id='1_1' would be row 1, page 1. </p>
<p>Just not sure how to structure the jquery to get this done. </p>
<p>FYI, I'm using php/mysql to output the info. So the above code would be one loop in that "while" statement. Subsequent loops would increase the row number (id="2_1", "2_2", etc.). </p>
<p>Thanks for any advice.</p>

Problem with Master pages event order
|
<p>I have a simple setup with the master page housing some controls used by all child pages.</p>
<p>I found when moving to new pages the master page page loads event fires as a non post back and read the solution was to store it's current values somewhere for retrieval. Ok all done.</p>
<p>The child page uses these values to run a report. When I switch to a new report, all is well. If I change the values in the master page the master page and the sub page load events fire. </p>
<p>The load event for the sub page fires first, picks up the values from the master page which are still the old values and then finally the master page events fire and all the new values are stored. The report hasn't changed as it still ran from the old values.</p>
<p>I can't really see a way around this. All you ever hear is that master pages are a saving grace but I swear i've never jumped through so many hoops to get a page to load correctly.</p>
<p>And now this!</p>
<p>Anyone see a plan to resolve it?</p>

Android: Taking complete control of phone, is it possible? How?
|
<p>We have a program that we install on the phones and borrow the phones to users for a certain period. We would like the phones to be used solely for running our application(no phone calls, no games, no nothing). We will root the phones, no problem with that. </p>
<p>So the things we need:</p>
<ul>
<li>Run in full screen, nothing else will be visible </li>
<li>Home button and other device buttons won't work</li>
<li>Our app will run automatically on
startup</li>
</ul>
<p>It doesn't have to be "hacker proof", but should be sufficient to prevent average user messing with the device.</p>
<p>Is this possible? I have done similar things on Symbian & Windows Mobile but I don't have much experience with this stuff on Android. Can you please point me in the right direction? </p>
<p>Thanks.</p>
