4,661,942 | 4,661,943 | Building iPhone App for Distribution | <p>I have a question on how exactly to do the final distribution build for my app. I have actually successfully built this app already but now I am trying to make an updated version and to remember what I did right the first time. It all seemed to go wrong when my provisioning profile expired....</p>
<p>Anyway, I have my distribution certificate and distribution provisioning profile. I have followed the instructions from Apple, an iPhone programming book and several online sources to create a build that checks against the right certificate etc. But the build always fails unless I connect a device, which is strange as the distribution provisioning profiles do not allow the inclusion of a device (which makes perfect sense in itself). However when I build with a device connected I am asked </p>
<blockquote>
<p>'Can’t run XXX on the iPod “iPod
touch”</p>
<p>The iPod “iPod touch” doesn’t have the
provisioning profile with which the
application was signed.</p>
<p>Click “Install and Run” to install the
provisioning profile XXX on “iPod
touch” and continue running XXX.'</p>
</blockquote>
<p>When I click install and run it fails with the message that </p>
<blockquote>
<p>A valid provisioning profile for this
executable was not found.</p>
</blockquote>
<p>So my basic question is how exactly should the final distribution build be done? An new executable appears, but it has a forbidden symbol on top of the application icon suggesting the build was unsuccessful. </p>
<p>Any help massively appreciated.</p>

829,081 | 829,082 | Assembly Resolve Not Fully Loading My DLL? | <p>I'm using a method to load a dll on an AssemblyResolve event. It's not quite working the way I want it to. Here's some code:</p>
<p>in my form load:</p>
<pre><code>var a = AppDomain.CurrentDomain;
a.AssemblyResolve += (object sender, ResolveEventArgs args) => LoadDLL(sender, args, anArg);
</code></pre>
<p>LoadDLL:</p>
<pre><code>public Assembly LoadDLL(object sender, ResolveEventArgs agrs, bool anArg){
//Let's just ignore anArg, it doesn't affect anything related to the problem
asseblyPath = @"XXX";//path to my dll
return Assembly.LoadFrom(assemblyPath);
}
</code></pre>
<p>So that's all well and good. I set Copy Local to false for my DLL so the AssemblyResolve event is called and I can load the desired version of my DLL. </p>
<p>One strange thing that is happening is this: After running this code, my code tries to access a public variable from a class containing global constant values (this class should be in my DLL). </p>
<pre><code>public class GCV{
public GCV(){}
public string value1= "asdf";
}
</code></pre>
<p>Unfortunately, when I'm in debug mode, GCV.value1 is set to null when it clearly has a value in the class definition. This is one symptom that I can describe here, hopefully enough to diagnose the problem? </p>
<p>Thanks!</p>

2,983,926 | 2,983,927 | Why can't you select top level elements in an HTML string with jQuery, and how do you get around it? | <p>I have some HTML stored in a string which I parse using jQuery. The HTML is something like:</p>
<pre><code><div class='person'>
<span class='name'>Joey</span>
<img class='avatar' src='...'/>
</div>
<div class='person'>
<span class='name'>Dee Dee</span>
<img class='avatar' src='...'/>

<img class='avatar' src='...'/>
</div>
<div class='person'>
<span class='name'>Johnny</span>
<img class='avatar' src='...'/>
</div>
</code></pre>
<p>So I use jQuery to parse the HTML like this (suppose the HTML is stored in the variable 'data'):</p>
<p><code>$(".name", data)</code> returns all the .name elements</p>
<p><code>$(".avatar", data)</code> returns all the .avatar elements</p>
<p>BUT <code>$(".person", data)</code> returns and empty object. </p>
<p><strong>So apparently jQuery cant parse the top level elements. Why is this? What is the best way to get around it?</strong> </p>
<p>Of course I can always insert 'data' inside a dummy element and then parse it, but that doesn´t seem a very elegant solution to me...</p>

We're building a c# application which will sit on PC's in garbage trucks. Things work fine on our development machines but as always, problems start to arise when we deploy onto our target hardware. </p>
<p>One in particular is giving us headaches. At random intervals we will get a windows message box popping up and saying that our application has encountered a problem and needs to be closed. </p>
<p>The application still works fine while the dialog box is sitting there, and obviously it closes when you click the close button. The frustrating thing is we get no exceptions, nothing in any logs, nothing in the system activity log. My hunch that there's some problem happening in a 3rd party library which we are using for GPS, which is a .net wrapper for an unmanaged dll which we've had problems with before. What options do we have to try and debug this?? I'm relatively new to windows programming and wondering if there are programs we can use to track which parts of a dll are being called by our code.</p>

3,979,677 | 3,979,678 | I'm trying to decipher my logcat info for an app that hangs up, and I need some pointers | <p>Here is some background on what I have going on. I am learning as I go, so I might have some difficuities with terminology. I have a main activity that needs to connect to a bluetooth module. The main activity creates an object called mChatService from another java file called BluetoothChatService.java.</p>
<pre><code>private BluetoothChatService mChatService = null;
</code></pre>
<p>So, in the main activity I have a function that is called connectDevice(). According to my logcat this function is entered into as expected. But when it reaches as certian line of code it hangs up. The line of code is this, mChatService.connect(device,secure); Now by checking the logcat errors this is what I find:</p>
<pre><code>1639 BluetoothService.cpp stopDiscoveryNative:D-bus error instopDiscovery:
org.bluez.Error.Failed(invalid discovery session)
</code></pre>
<p>Also another window pops up next to my java files, that reads:</p>
<pre><code>ActivityThread.deliverResults(ActitvityThread$ActivityClientRecord, List) line: 2655
</code></pre>
<p>So, my question is, Is this enough info to suggest a possible explanation of the problem that is occuring? If not, what would be my next step in gathering info that might be useful for debugging?</p>

The full list of modules is obtained from sys.modules (and I filter the list to focus on only those modules which are part of my package).</p>
<p>Reloading individual python files seems to work in some cases and not in other cases. I guess, all the modules which depend on a modified module should be reloaded and the reloading should happen in proper order. </p>
<p>I am looking for a way to get the list of modules imported by a specific module. Is there any way to do this kind of introspection in Python?</p>
<p>I understand that my approach might not be 100% guaranteed and the safest way would be to reload everything, but if a fast approach works for most cases, it would be good enough for development purposes. </p>
<p><strong>Response to comments regarding DJango autoreloader</strong></p>
<p>@Glenn Maynard, Thanx, I had read about DJango's autoreloader. My web app is based on Zope 3 and with the amount of packages and a lot of ZCML based initializations, the total restart takes about 10 seconds to 30 seconds or more if the database size is bigger. I am attempting to cut down on this amount of time spent during restart. When I feel I have done a lot of changes, I usually prefer to do full restart, but more often I am changing couple of lines here and there for which I do not wish to spend so much of time. The development setup is completely independent of production setup and usually if something is wrong in reload, it becomes obvious since the application pages start showing illogical information or throwing exceptions. Am very much interested in exploring whether selective reload would work or not. </p>

1,161,803 | 1,161,804 | C++ for Game Programming - Love or Distrust? | <p>In the name of efficiency in game programming, some programmers do not trust several C++ features. One of my friends claims to understand how game industry works, and would come up with the following remarks:</p>
<ul>
<li>Do not use smart pointers. Nobody in games does.</li>
<li>Exceptions should not be (and is usually not) used in game programming for memory and speed.</li>
</ul>
<p>How much of these statements are true? C++ features have been designed keeping efficiency in mind. Is that efficiency not sufficient for game programming? For 97% of game programming? </p>
<p>The C-way-of-thinking still seems to have a good grasp on the game development community. Is this true?</p>
<p>I watched another video of a talk on multi-core programming in GDC 2009. His talk was almost exclusively oriented towards Cell Programming, where DMA transfer is needed before processing (simple pointer access won't work with the SPE of Cell). He discouraged the use of polymorphism as the pointer has to be "re-based" for DMA transfer. How sad. It is like going back to the square one. I don't know if there is an elegant solution to program C++ polymorphism on the Cell. The topic of DMA transfer is esoteric and I do not have much background here. </p>
<p>I agree that C++ has also not been very nice to programmers who want a small language to hack with, and not read stacks of books. Templates have also scared the hell out of debugging. Do you agree that C++ is too much feared by the gaming community?</p>
