1,565,453 | 1,565,454 | Java - Storing a "score" from play to play | <p>I wish to be able to keep a score that a player gets when playing my game from game to game and to when they close the game and re-open the scores are still saved. The only way I can think of is to do so using a text file, like I would of done in VB6. However, that then means that they can edit the text file? Or not? My score is stored in a "double" that can be accessed from any class and is being transferred around classes as it is, if that makes a difference.</p>
<p>Hope someone can suggest the best way to go about this.</p>

It's supposed to open a test window, and <strong>IF</strong> successful, close the test and redirect the parent. I'm still getting into java.

1,915,773 | 1,915,774 | Write a python script that goes through the links on a page recursively | <p>I'm doing a project for my school in which I would like to compare scam mails. I found this website: <a href="http://www.419scam.org/emails/" rel="nofollow">http://www.419scam.org/emails/</a>
Now what I would like to do is to save every scam in apart documents then later on I can analyse them.
Here is my code so far:</p>
<pre><code>import BeautifulSoup, urllib2

html = urllib2.urlopen(address).read()
f = open('test.txt', 'wb')
f.write(html)
f.close()

<pre><code><a href="2011-12/01/index.htm">01</a>
<a href="2011-12/02/index.htm">02</a>
<a href="2011-12/03/index.htm">03</a>
</code></pre>
<p>etc.</p>
<p>If i get that, I would still need to go a step further and open save another href. Any idea how do I do it in one python code?</p>

4,516,050 | 4,516,051 | Back button issues after forwarding intents via share menu | <p>I am working on a login screen for my application. If I open the application, by either running from eclipse or by selecting the application icon installed on the emulator, it will run an AuthUser.class which checks for a valid token on a remote server. If the user is not logged in then the AuthUser.class forwards to Login.class via...</p>
<pre><code>if (authtoken.length() == 0 || authtoken.length() > 0
&& checkAuthToken(authtoken) == false) {
Intent intent = new Intent();
intent.setClass(AuthUser.this, Login.class);
startActivity(intent);
finish();
}
</code></pre>
<p>This works great, as when I use the back button on the emulator it will close the app rather than go back to the login screen. Perfect.</p>
<p>Now when I am coming from a share menu, like when I select share icon on an image within the gallery, and then select my application from the popup menu I also forward to the Login.class via...</p>
<pre><code>Intent intent1 = new Intent();
intent1.setClass(SharePictureMenu.this, AuthUser.class);
startActivity(intent1);
finish();
</code></pre>
<p>Now when I login from here and it forwards to AuthUser.class as per usual, however, the back button press now takes me back to the login screen, even though I am forwarding and finishing exactly the same in both cases. Obviously I don't want that behavior as I want it to close the app and return to the gallery after login so the user can continue to share images immediately without having to go back through the login screen.</p>
<p>Any suggestions, hacks or otherwise on fixing this would be greatly appreciated.</p>

}
else
{

}
}
else

<p>The issue is as the value of variable_a changes when the state of the checkbox A, the value of variable_b doesn't change as this is within the checkedChangeListener. So any advice to overcome this is much appreciated.</p>

<pre><code>Fatal error: Call to undefined function: stripos() in...
</code></pre>
<p>I do not want it to be an exact match, basically if the <code>$_SESSION['website']</code> is www.google.com, I'd want <code>stripos</code> to return <code>true</code> if <code>$f['website]</code> is www.goog.com</p>
<p>Am I doing something wrong, or is there a better way to do this?</p>
<p>edit: I was doing some testing, and noticed if my <code>$_SESSION['website']</code> variable contains <code>www</code> and <code>.com</code>. As does my <code>$f['website]</code> variable. shouldn't <code>strpos</code> return that as true?</p>

On the product pages there is a form using GET with a series of form elements (drop downs, check boxes, sliders etc) who's values are used to construct the final MySQL query for pulling the right products based on the users selections. To construct my query, I go through the $_GET array and construct it accordingly.

398,490 | 398,491 | FormView + FileUpload - can I change a bound field based on the fileupload? | <p>I have a FormView control in an ASP.NET 2.0 app. I've got the database storing a filename (a person's picture) in a column. I can't bind the value of the column to a fileupload control - so I'm trying to use a hidden form field. Here's what I have:</p>
<pre><code><asp:HiddenField ID="pictureLink" runat="server" Value='<%# Bind("pictureLink") %>' />
<asp:FileUpload ID="pic" runat="server" />
</code></pre>
<p>Code Behind:</p>
<pre><code>//ItemUpdating event handler
void do_update(object sender, FormViewUpdateEventArgs e)
{
FileUpload newpic = (FileUpload)profile_edit.FindControl("pic");
if (newpic.HasFile)
{
//do a bunch of file uploading "stuff" which makes a new file name
e.Keys["pictureLink"] = new_filename;
}
}
</code></pre>
<p>My goal is to update the hidden form field's value to the newly updated file name so the database is properly updated.</p>
<p>I think I'm close - but it seems like I can't programmatically alter any of the bound data fields after-the-fact.</p>
<p>I've tried using javascript to change the control - but the new file name will actually be different than what they upload; which javascript can't necessarily "predict" and reliably put the correct file name into the hidden form field</p>
<p>Any suggestions?</p>
<p>Thanks</p>

4,029,212 | 4,029,213 | Globals and singletons in Python | <p>I have some few classes which are widespread in my Python application and which should have only one global instance (eg Logger, DbConnection). Python does not support static variables/methods in a class, so the usual Java/C++ way to create a singleton here does not work. I have looked for alternatives to implement singleton in Python. I want a simple (no metaprogramming if possible) and clean implementation. This looks good:</p>
<pre><code>class MyClass(object):
def a():
pass
singleton = MyClass()
</code></pre>
<p>Using the singleton would be simple as</p>
<pre><code>import myClass
myClass.singleton.a()
</code></pre>
<p>The direct assignment could be replaced by a creation function if object initialization is not so simple.</p>
<p>I could also create a getInstance() in module scope and always use it to get myObj.</p>
<p>Question 1) This works ok? The module code (myObj assignment) only runs the first time it is imported into some other module and myObj won't be created every time I import this module somewhere?</p>
<p>An alternative method I have seen is to use a globals module. Something like:</p>
<pre><code>from myClass1 import MyClass1
from myClass2 import MyClass2
myObj1 = MyClass1()
myObj2 = MyClass2()
</code></pre>
<p>Using this:</p>
<pre><code>import globals
globals.myObj1.a()
</code></pre>
<p>I tend to prefer the first alternative. </p>
<p>Question 2) Between the 2 solutions, what do you recommend? </p>
<p>Question 3) A third solution would be passing the widespread objects such as Logger to several classes/functions, but this is not a good solution imho. Is there a better solution not mentioned here ?</p>
<p>I'm aware of the downsides of using global variables and singletons. However, having a global state is not a big issue in my application. I'll prefer solutions that have code clarity and are simple to use. </p>
