I've never managed to find anything relating to this in distutils documentation though so how do other people solve this problem?</p>

613,697 | 613,698 | Android wizard-like (step by step) application | <p>I'd like to build an android step application so I can go back and forth between activities.</p>
<p>I'd like to create a base class for the step manager that includes two buttons to go forward and back, so in the child activities I don't have to recreate those controls every time. The step manager class has to take care of the switching between activities in a precise order and of passing data between them.</p>
<p>I tried to write some code but I can't merge the parent's layout with the child one!</p>
<p><code>
FrameLayout fl = (FrameLayout)this.findViewById(R.id.frame);<br>
LayoutInflater.from(this).inflate(rId, fl, true);
</code></p>
<p>This code is in the parent class (inherited from Activity): </p>
<ul>
<li>the FrameLayout is the place holder for the child-layout controls;</li>
<li>rId is the layout resource ID of a LinearLayout in the child xml layout.</li>
</ul>
<p>I guess that the problem about that code is that I don't call the setContentView of the child layout, so anytime I use the findViewById of a child control I get a null pointer.</p>
<p>What is the best practice to create something like that? </p>
<p>Thanks, Simone.</p>

requestDir.Credentials = new NetworkCredential("sh","se");

<p>Using the same code to create the directory structure to connect my local Filezilla ftp server to do the job---Works Fine.</p>
<p><strong>Scenario 2:</strong>
Used the above code to connect the remote ftp server to do the same job throws exception : Error 550 no file found or no Access.</p>
<p><strong>Question 1</strong> : I have a full permission to read/write for the folder,if its not a permission issue,what else i have to keep it in mind to look for it ?</p>
<p><strong>Question 2</strong>: If i modified my code like
step1: Make"mpg" direcotry first
step2: make"test" directory after that,works fine
is that mean FTP.Makedirectory won't support to create a subdirectory in the main dir ?</p>
<p>If that's the case how it created in my local ftp server ?</p>

1,330,674 | 1,330,675 | How can I create subclass at run-time to map some properties then cast it back to parent class? | <p>Consider this <code>People</code> class:</p>
<pre><code>public class People
{
public virtual string Name { get; set; }
public virtual ushort Age { get; set; }
}
</code></pre>
<p>I have some third party implementations that can obtain people data but with a little variations. For example, I have a method that is able to retrieve data for <code>StrangePeople</code>:</p>
<pre><code> public class StrangePeople
{
public string Name { get; set; }
public DateTime BirthDate { get; set; }
}
...
StrangePeople someone = GetData<StrangePeople>();
</code></pre>
<p>Due to the amount of classes and variations I trying to found a way to generate a runtime subclass of <code>People</code> that can translate the data so I can cast it back to <code>People</code> later. In other words, with minimum effort generate a subclass like this:</p>
<pre><code>public class StrangePeopleTranslator : People
{
private ushort? _mAge = null;
public override ushort Age
{
get
{
if (_mAge == null)
{
DateTime today = DateTime.Today;
int age = today.Year - BirthDate.Year;
if (BirthDate > today.AddYears(-age)) age--;
_mAge = age;
}
return _mAge.GetValueOrDefault();
}
set
{
_mAge = value;
}
}
public DateTime BirthDate { get; set; }
}
...
People someoneElse = (People)GetData<StrangePeopleTranslator>();
</code></pre>
<p>Maybe the run-time subclass it's bit overkill... I don't know.</p>

3,394 | 3,395 | What is the most Pythonic way to use an empty dictionary as a default argument? | <p>Using default arguments of the form <code>x={}</code> usually does not accomplish the intended purpose in Python, since default arguments are bound when a function is defined, not called.</p>
<p>The convention seems to be to set mutable objects as default arguments with <code>x=None</code> and then check <code>x is None</code> to assign the proper default when the function is called.</p>
<p>So if I would like to cast <code>x</code> to a dictionary that is by default empty, I would use something like the following:</p>
<pre><code>def f(x=None):
x = dict(x) if x is not None else {}
</code></pre>
<p>However, since <code>dict</code> can take any iterable, I could also write this more succinct version:</p>
<pre><code>def f(x=()):
x = dict(x)

103,880 | 103,881 | Java Command Prompt Exit | <p>I have a short question concerning the Runtime.getRuntime.exec("") command in java.</p>
<p>I am trying to make a tunnel to a gateway computer via SSH:</p>

Runtime.getRuntime().exec(tunnel);

<p>This bit of code works properly except the annoying fact that a command prompt appears.</p>
<p>Now I tried to exit the prompt after executing the code:</p>
<pre><code>String tunnel = "C:\\Program Files\\PuTTY\\putty.exe -ssh -X -P " + localPort + " " + tempUsername + "@" + localIP

<p>Is it possible to close the command prompt in a similar way like I do or are there better ways? (This code doesnt work)</p>

<p>Trying this sample code which I found in StackOverflow...</p>
<pre><code>std::string text = "¯"; // AF in HEX ASCII.
std::ostringstream result;
result << std::setw(2) << std::setfill('0') << std::hex << std::uppercase;
std::copy(text.begin(), text.end(), std::ostream_iterator<unsigned int>(result, " "));

<p>result.str() will be 'FFFFFFAF' instead of just 'AF'</p>
<p>What can I do?</p>
<p>My text can have more than one character, like that: text = '¯ABCÈ'; // AF414243C8
The result after 'convertion' is: FFFFFFAF414243FFFFFFC8.</p>
<p>.</p>
<p>Well, I solved it with a replace... it's not a good practice in this case, but solved.</p>

4,021,734 | 4,021,735 | Problems with deltaTicks combined with high speed in a game loop | <p>My game uses a d = vt calculation for movement of objects where t is the time since the last frame (one frame per loop). </p>
<p>I'm using SDL and the gist of the timing calculation is that I create an instance of a Timer class and start it. I call GetSeconds() when it's needed which returns the difference between when the timer was started and the current time (divided by 1000 because everything is in milliseconds).</p>
<p>Ex:</p>
<pre><code>return (SDL_GetTicks() - m_StartingTicks) / MILLISECONDS_PER_SECOND;
</code></pre>
<p>After each loop the timer is reset. I.e. <code>m_StartingTicks = SDL_GetTicks()</code> However, I recently changed this so that it's only reset <code>if m_StartingTicks is < SDL_GetTicks</code>, but it didn't fix the problem.</p>
<p>This was all hunky dory until I recently wrote a game engine to handle different game states and various other things which are used in my main game loop. This seriously improved performance, but unfortunately each iteration of the game loop is now occuring in less than 1 millisecond so when I pass GetSeconds(), 0 is returned and things on the screen don't move.</p>
<p>The easiest way to handle this is a simple kludge where if <code>SDL_GetTicks() - m_StartingTicks) == 0</code> I change it to a 1 (as in 1 millisecond instead of 0). I don't really like this though, and I'd like to hear any suggestions, fixes, improvements, etc.</p>
<p>If you need more info I'd be happy to offer it.</p>
