4,471,111 | 4,471,112 | Freezing Android APK version for older SDKs | <p>I understand how multiple APKs work on Google Play, but so far I've supported a single APK for V7 (2.1) and up. I'd like to start using Android 3.x-4.x+ features that could be more difficult to make backwards compatible, and I wouldn't mind not having to build in that growing compatibility library. But I still want to make the product available to Android 2.x users, even though that version will be "frozen" and not receive future product enhancements.</p>
<p>So how should this best be done? I could use the basic multiple-APK approach, but then users of 2.x devices might see things in the product description that are not in the APK that they would be installing. But would the version number show up correctly based on the APK that matches the user's device?</p>

1,098,303 | 1,098,304 | If module `example` contains both function `run` and submodule `run`, can I count on `from example import run` to always import the former? | <p>If I have a Python module implemented as a directory (i.e. package) that has both a top level function <code>run</code> and a submodule <code>run</code>, can I count on <code>from example import run</code> to always import the function? Based on my tests that is the case at least with Python 2.6 and Jython 2.5 on Linux, but can I count on this generally? I tried to search information about the import priorities but couldn't find anything.</p>
<p>Background:</p>
<p>I have a pretty large package that people generally run as a tool from the command line but also sometimes use programmatically. I would like to have simple entry points for both usages and consider to implement them like this:</p>
<p><code>example/__init__.py</code>:</p>
<pre><code>def run(*args):
print args # real application code belongs here
</code></pre>
<p><code>example/run.py</code>:</p>
<pre><code>import sys
from example import run
run(*sys.argv[1:])
</code></pre>
<p>The first entry point allows users to access the module from Python like this:</p>
<pre><code>from example import run
run(args)
</code></pre>
<p>The latter entry point allows users to execute the module from the command line using both of the approaches below:</p>
<pre><code>python -m example.run args
python path/to/example/run.py args
</code></pre>
<p>This both works great and covers everything I need. Before taking this into real use, I would like to know is this a sound approach that I can expect to work with all Python implementations on all operating systems.</p>

5,641,491 | 5,641,492 | Py_Initialize and Py_finalize and MatPlotlib | <p>This is a known problem, but I want to ask the experts for the best way to solve it for me. </p>
<p>I have a project (Euler Math Toolbox), which runs Python as a script language. For this, a library module "python.dll" is loaded at run time, which is linked against "python27.lib". Then Py_Initialize is called. This all works well. </p>
<p>But Euler can be restarted by the user with a new session and notebook. Then I want Python to clear all variables and imports. For this, I call Py_Finalize and unload "python.dll". When Python is needed, loading and initializing starts Python again. </p>
<p>This works. But Python crashes at the first call, if MatPlotlib is imported in the previous session. It seems that Py_Finalize does not completely clear Python, nor does unloading my "python.dll". I tried unloading "python27.dll" (the Python DLL), but this does not help. Most likey, another DLL remains active, but corrupts during Py_Finalize. </p>
<p>To solve this, it would suffice to clear all variables and imports. I could live with not calling Py_Finalize. But how? </p>
<p>PS: You may wonder, why I do not directly link euler.exe to Python. The reason is that this prevents Euler form starting, if Python is not installed, even if it is never needed. </p>

1,103,408 | 1,103,409 | php - generate non linear urls | <blockquote>
<p><strong>Update:</strong></p>
<p>Ok.. I have read a lot of solutions...
Thank you so much everybody. I think I
will keep it simple and avoid the
encryption and just rely on two fields
matching in the database. I can keep
the id as it is (sequential) but add
for example a timestamp (with :
removed). Then I can put both through
the youtube style url generator...
leaving me with a really short, unique
and not easily guessed url. e.g</p>
<p>before the youtube url gen blah.com?id=10345&s=134025</p>
<p>after blah.com?id=H2s&s=tL2s</p>
<p>I log the unique views to each id anyway...
so I will record unsucessful ones too
and if a user hits 10 non matching
url's in an hour then I can block his
ip (I know a proxy will evade
this...but it makes it more
difficult). </p>
<p>What do you think?</p>
</blockquote>
<p>This may sound like a bit of an odd question... what I am looking to achieve is a way to generate an id to be used in a url which can not be guessed or calculated. What I mean is it is not id=1, id=2...</p>
<p>I was looking at a youtube style script <a href="http://stackoverflow.com/questions/1853471/php-help-improve-the-efficiency-of-this-youtube-style-url-generator">here</a>. Which has a padding option, but the padding is so obvious with urls like wTTTa and b666o. I considered MD5 ing the id... but thats hardly foolproof and makes for rather long urls.</p>
<p>The solution must be url based (can't be cookie or session based) and before you panic and think that I am trying to work out a way to secure my admin page - i am not, its part of a game I am developing.</p>

I need to use a button because it needs to generate the link based on criteria data entered in the form (string manipulation). This button is not submitting the form though; it’s just validating some of the data on an external site. I need this in a different window or tab so they can go back and forth between my form and the validation site. This is basically my current <code>Button_Click</code> event:</p>

For example, I want to test printer functionality so it has constructor, open printer connection, send data to printer, close printer connection. So the XML would be:</p>
<pre><code><Printer>
<TestCaseName>"Printer_Construct"</TestCaseName>
<Data1>"Printer1"</Data1>
<TestCaseName>"Printer_OpenConnection"</TestCaseName>
<Data1>"Printer1"</Data1>
<TestCaseName>"Printer_PrintString"</TestCaseName>
<Data1>"Printer1"</Data1>
<Data2>"Printing my string"</Data2>
<TestCaseName>"Printer_CloseConnection"</TestCaseName>
<Data1>"Printer1"</Data1>
</Printer>
</code></pre>
<p>Here is how my test framework wanted to work:</p>
<p>1- when test operator runs the test framework, first it will load all the case names only into listbox1. It will not load test case data yet.</p>
<p>2- when test operator selects specific test case to run, it will load that test case into listbox2. So when it loads test case into listbox2, it will display test case name and test data(data1 and data2 as shown in xml struct above).</p>
<p>3- So now that test case in listbox2 is ready to be tested whenever test operator clicks the Run button.</p>
<p>So how can I store test case data? Should I store these data in memory? If so, what storing data feature should I use? If not storing these data in memory, does that means I will have to read the XML every time when accessing to test case data so is it good practice to do that?</p>

I want to update the icon on a row with a "selected" icon, and update the previously-selected row with an "unselected" icon.

<p>Following up on a related but tangential question ( <a href="http://stackoverflow.com/questions/13684264/how-to-disambiguate-function-templates-that-differ-only-by-return-type">How to disambiguate function templates that differ only by return type?</a> ), I would like to ask a question related to the fact that the <em>return type</em> of a function is not considered to be part of the signature of a function.</p>
<p>Consider the following code:</p>
<pre><code>#include <iostream>
int foo()
{
return 0;
}
int main()
{
long n = static_cast<long(&)()>(foo)(); // Error: incorrect return type
int p = static_cast<int(&)()>(foo)(); // Compiles just fine
}
</code></pre>
<p>The line of code noted above results in a compilation error, because the <em>return</em> type of the function type to which <code>foo</code> is being cast does not match the <em>return</em> type of the function <code>foo</code>.</p>
<p>But I thought the return type of a function does not play a role in the signature of the function!</p>
<p>According to a certain line of thinking, since the function signature <code>long(&)()</code> matches the signature of <code>foo</code>, the cast of <code>foo</code> to a function of this type should succeed.</p>
<p>However, the cast does not succeed. Where does the reasoning go wrong? If the cast cannot fail due to the function signature, then why does the cast fail?</p>
