<p>I have 2 options. Let me know which is best ?</p>
<ol>
<li>Target and code for IOS4. and that will work fine in IOS5 also, i think.</li>
<li>BaseSDK IOS5 and target IOS4 .(I am not planning to use ARC or storyboard for now anyway ).</li>
</ol>
<p>I think with method #2, i have to be extra careful while using each usages at the same time as i am not using story board and ARC , there are no benefits. So hope #1 is better.</p>
<p>Let me know expert opinion. </p>
<p>Note: in future if need to switch to IOS5 new features , hope only this ARC will be the blocking and that is also an optional thing and i can easily switch rt?</p>

1,848,680 | 1,848,681 | How to get the most recent National Weather Service radar images? | <p>I am trying to get the most recent NWS radar images using c#. There are <a href="http://radar.weather.gov/ridge/RadarImg/NCR/OKX/?C=M;O=D" rel="nofollow">directories</a> on the NWS website that contain a list of the most recent images. However, the files are named by the date uploaded, not in numerical order. They are generally uploaded every few minutes, but the exact amount of minutes can vary by as much as 5 minutes. To get the URLs of the images, I could write an XML parser to extract the URLs from the index page, however this seems over complicated for such a simple task. In addition, this index page is not an API, and if they might change something with the format that would screw up the XML parser. Is there some other way to get the URLs of the most recent images?</p>

3,591,181 | 3,591,182 | Android non-root lock replacement | <p>Let me begin by saying that, yes, I know that the stock Android lock screen can not be programatically replaced without rooting. </p>
<p>Now that that's over with, I want to make an app that contains a custom 'lock' mechanism. There are apps out there that emulate this functionality, namely LockGo. This allows a user to view information from widgets on a 'lock screen' and emulates the slide-to-unlock functionality (or whack-a-mole if the user wants to install that plugin). </p>
<p>Does anyone know what mechanism or Android API functionality they may have used to do this? Is it as simple as hooking into the power button to launch an activity, such as in the link below?</p>

The context is provided via constructor or via getApplicationContext() from a surrounding Activity.

<p>E.g. in the doInBackground() I use the context in order to Instantiate an DAO class.</p>
<pre><code> @Override

ExampleDao dao = new ExampleDao(context);

<p>I saw several examples doing that in this way, but I cannot image that this is thread-safe, because the context is now accessed by the main tread (UI Thread) and the worker thread. </p>

<p>The contentMode for the UIImageView is set as ScaleAspectFit and as soon as I increase the frame size of the UIImageView, the UIImage size also increases (and is not affected by the drawInRect:)</p>

<li><p>Place a UIImageView on the screen with the size same as the size of the image</p></li>
<li><p>When the user selects the image, anywhere he touches, the image edits as if the user is doing multi-touch with the image</p></li>

<p>One thing that I would like to include is the ROM provider. In particular I would like to know if the user is running a custom ROM and which, preferably even with the version number.</p>
<p>Any idea how to retrieve this information programmatically?</p>

return (modVer == null || modVer.length() == 0 ? "Unknown" : modVer);

<p>Whereby the constant is this: </p>
<pre><code>public static final String SYS_PROP_MOD_VERSION = "ro.modversion";

<p>And here is the getSystemProperty();</p>
<pre><code>public static String getSystemProperty(String propName){

<p>Could anybody with a CM ROM can run this for me?</p>
<p>Btw. Careful, this is GPL code. I for one can not use it.
Any easier or non-GPL way?</p>

5,282,873 | 5,282,874 | Read first half of file contents and echo and then the second half | <p>I have a text file that lists the name of a track then after a double space the artist is listed. In order for me to fetch the album art from Last.fm I have to have both the title and artist in the the URL like <code>http://ws.audioscrobbler.com/2.0/?method=track.getinfo&track=TRACK TITLE&artist=ARTIST</code>. Since the artist and track title aren't in separate files, is there a way I can get the part before the double space and call it $title and the part after the double space and call it $artist, so I can just echo it into the URL?</p>
<p>This is what I currently have to get the file contents:</p>
<pre><code><?php
$current = file_get_contents('RBDS%20Text.txt');
echo $current;
?>
</code></pre>
<p>Thanks!</p>
<p>EDIT:</p>
<p>So the text file outputs the "track title [double space] artist"</p>
<p>For Last.FM I have to have in the URL <code>track=TRACK TITLE&artist=ARTIST</code></p>

I'm using a .cpp file which contains the class and all it's methods, a .hpp file which contains linked libraries.
If I want to compile a file having the main function, how to do this? Should I declare an extern class?
Can I have an example of how linking classes?</p>
<p>This is the class in the cpp file:
<a href="http://pastebin.com/aQqT0GNx" rel="nofollow">http://pastebin.com/aQqT0GNx</a></p>
<p>This is the .hpp file:</p>
<pre><code>#ifndef LIST_HPP
#define LIST_HPP
#include <iostream>
using namespace std;
#endif
</code></pre>
<p>This is the main file:</p>
<pre><code>#include "List.hpp"
int main(int argc, char **argv)
{
List<int>l;
return 0;
}
</code></pre>
<p>It says 'List' is not declared on this scope.</p>
