4,682,552 | 4,682,553 | User cannot install to device with android 4.0.4 even though app supports APIs 3 - 16 | <p>I have a user with Motorola XT910 with android 4.0.4 reported he is unable to download my application from the Google Play Store. The error states the device is not compatible with the current version; however, my application supports APIs 3 - 16 which should include android 4.0.4.</p>
<p>I currently have API 16 and SDK Tools r20, and from the android revision history (http://developer.android.com/tools/revisions/platforms.html) I can see API 15 revision 3 is needed for Android 4.0.4. I haven't been able to download revision 3 as it doesn't show up in the SDK Manager, but shouldn't API 16 cover that? or am I making a wrong assumption?</p>
<p>Do I need to download revision 3 of the API 15 or does having API 16 covers it?
If it's needed, what can I do so that this particular revision shows up in the SDK Manager? Or is it possible to download elsewhere without using the SDK manager.</p>

99,408 | 99,409 | Getting offset from index in binary file | <p>Well, the question says it all. I'm looking for the value in a binary file, and it's location is in the index of the binary file. I'm using the following code, and its not getting me the right bytes back out of the binary file. I'm getting the correct value from the first read, at 0xC, but I'm not converting the offset right. I tried converting it to a string first and getting the right string value, but the moment I try to get it to long its searching the wrong area. Also note that the data I need is actually ox60 BEFORE the index location given to me in the binary.</p>
<pre><code> long offset = 0;
//Open read stream
Stream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
BinaryReader brFile = new BinaryReader(fileStream);
//Read index to find start position
fileStream.Seek(0xC, SeekOrigin.Begin);
byte[] b = brFile.ReadBytes(4);
//Convert to long value
for (int x = 0; x < byErr.Length; x++)
offset = System.Convert.ToInt64(b[x].ToString()); //I'm assuming this is the problem
//Cleanup
fileStream.Flush();
b = null;
//Read needed value
fileStream.Position = offset;
fileStream.Seek(-0x60, SeekOrigin.Current); //The value I need is 0x60 BEFORE the index location
b = brFile.ReadBytes(4);
//Cleanup

One can subscribe multiple delegate instances to a delegate by the "+=" operator.

<p>In simplified code (omitting access modifiers etc.):</p>
<pre><code>class Car
{
void Start();
void Drive();

// I would like to have the following class generated automatically

// without declaring a delegate instance for each of them

StartAll += anotherCar.Start;
DriveAll += anotherCar.Drive;
}
}

<p>EDIT:
Rawling's solution is the one that I like best. It's simple and clear.

Of course such usage of "dynamic" is not of everyone's taste...</p>

{
public void CallAll(Action<dynamic> action)
{
foreach (dynamic t in this)
{
try {action(t);} catch (RuntimeBinderException) {};
}
}
}
class Bike
{
void Drive();
}
CallAller2 ca = new CallAller2();
ca.Add(new Car());
ca.Add(new Bike());
ca.CallAll(c => c.Start()); // is ignored by Bike which does not implement it
ca.CallAll(c => c.Drive());

4,368,202 | 4,368,203 | Javascript beginner: how to replace a href text if it matches a specified string? | <p>When someone posts a link to another page on my website, I'd like to shorten the a href text from something like: <code>http://mywebsite.com/posts/8</code> to <code>/posts/8</code> or <code>http://mywebsite.com/tags/8</code> to <code>/tags/8</code>. Since I'm learning javascript I don't want to depend on a library like prototype or jquery. Is it recommended to use javascript's <code>replace</code> method?</p>

1,344,304 | 1,344,305 | Pagination Standards | <p>Does anyone know of a defined standard for Pagination? We have a consultant company that buildt a website for us and part of the site has a list of items that uses pagination. They have a pretty standard pagination layout consisting of two buttons on either side of a list of numbers (links). </p>
<pre><code>[<<] [<] 1 2 3 4 5 [>] [>>]
</code></pre>
<p>The buttons [<] and [>] move you through the pages, either back on or forward one. THe numbers are all direct links to the pages.</p>
<p>The problem I have is with the buttons with the double 'arrows'. I think these should take you to the First or Last page. Everyone here agrees with that and expect it to work that way. However, the company that has designed the site has those buttons jumping 10 pages forward or backwards. I"ve never seen this done like this, and so the expected behavior isn't what myself and other users are expecting. This site just went live last night and we've already had 3 users report this functionality as a bug.</p>
<p>Is there a set of standards I can use for this to show the consultants? They don't want to change this functionality.</p>

3,142,219 | 3,142,220 | Best practices for creating an exception log file in PHP on a public website | <p>I am currently running on a homegrown PHP framework that outputs a nicely formatted HTML document with lots of great information when an exception is encountered and it is running in debug mode. </p>
<p>When it is running in production on the public site, debug mode is off and it simply returns a proper message to the user. Everything works just as it should. Except for the fact that it doesn't log errors in the production environment. I'd like for it to take the HTML documents that it creates in my development environment and, instead of displaying to the user (obviously), store them somewhere. </p>
<p>The issue I'm running into is that PHP cannot create a file above the root nor can it create a file within the root in a folder that is anything but wide-open. Due to the very explicit nature of my error reporting, I need to store this information in a secure environment and in a public folder in the public root doesn't seem like the best place. </p>
<p>I realize the other options are to put this info in a database but if the error is a database connection issue, that's no good. And it can be emailed but again, if there is a connection issue to the SMTP server, that's no good. Plus, I don't want to spam myself if something goes really haywire. </p>
<p>So, what is the best practice here? I'm certain I'm just missing something obvious. Thank you.</p>

<p>Anton suggests <a href="http://www.nablasoft.com/alkampfer/index.php/2008/08/04/implement-inotifypropertychanged-with-castledynamicproxy/">dynamic proxies</a>. I've actually used the "Castle" library for something similar in the past, and while it does reduce the amount of code I've had to write, it added around 30 seconds to my program startup time (ymmv) - because it's a runtime solution.</p>
<p>I'm wondering if there is a compile time solution, maybe using compile-time attributes...</p>
<p><hr /></p>
<p>Slashene and TcKs give suggestions which generates repetitive code - unfortunately, not all my properties are a simple case of m_Value = value - lots of them have custom code in the setters, so cookie-cutter code from snippets and xml aren't really feasible for my project either.</p>

<p>Here is what I currently got</p>
<pre><code>$("#posts").click(function () {
$("#sideboxtopleft").toggleClass("2");
$("#arrow").toggleClass("2");

<p>Pretty much posts is the link, when when you click on it. It would make sideboxtopleft and arrow, sideboxtopleft2 and arrow2 and when you clicked on comments it would take off the 2 of both of those.

Precisely, there is a cometchat direvtoru that contains php files. The latter only need the $_SESSION['user'] to process. But it didn t and I think I have a path problem for my code to transmit the user's session info.</p>
<p>On the side of my code, I have the following architecture : essentially three directories</p>
<ul>
<li>classes (containing all my php files except index.php, the account.php generate the user session)</li>
<li>templates (containing all my html files)</li>
<li>public containing - index.php
- css directory
- js directory
- cometchat directory</li>
</ul>
<p>index.php process the php files of 'classes' and then the latter files process the html files using the smarty engine.</p>
<p>I tried to call the config files of the cometchat directory by proceeding to a require_once path/config.php in the index.php but it didn t work. So I have perhaps a silly question but : if I call this config file in index.php, and knowing that index.php instanciate an account class of account.php file (where the user's session is created), does the require_once path/config.php will retrieve the session info. More generally, could anypne help to deal with this problem? </p>

<p>And I only get the caption from the last field. When I added check boxes to the form it all worked fine provided I only checked 1 but if I checked 2 or more it would only give me the value for the last one.</p>
<p>I also tried this:</p>

<table id="myTable2">

647,245 | 647,246 | Multiple 'endings' to a function - return an object, return a string, raise an exception? | <p>This one's a structure design problem, I guess. Back for some advice.</p>
<p>To start: I'm writing a module. Hence the effort of making it as usable to potential developers as possible.</p>
<p>Inside an object (let's call it <code>Swoosh</code>) I have a method which, when called, may result in either success (a new object is returned -- for insight: it's an <code>httplib.HTTPResponse</code>) or failure (surprising, isn't it?).</p>
<p>I'm having trouble deciding how to handle failures. There are two main cases here:</p>
<ol>
<li>user supplied data that was incorrect</li>
<li>data was okay, but user interaction will be needed () - I need to pass back to the user a string that he or she will need to use in some way.</li>
</ol>
<p>In (1) I decided to <code>raise ValueError()</code> with an appropriate description.
In (2), as I need to actually pass a <code>str</code> back to the user.. I'm not sure about whether it would be best to just <code>return</code> a string and leave it to the user to check what the function returned (<code>httplib.HTTPResponse</code> or <code>str</code>) or <code>raise</code> a custom exception? Is passing data through raising exceptions a good idea? I don't think I've seen this done anywhere, but on the other hand - I haven't seen much.</p>
<p>What would you, as a developer, expect from an object/function like this?</p>
<p>Or perhaps you find the whole design ridiculous - let me know, I'll happily learn.</p>
