<p>When obtaining the DPI for the screen under Windows (by using ::GetDeviceCaps) will the horizontal value always be the same as the vertical? For example:</p>
<pre><code>HDC dc = ::GetDC(NULL);
const int xDPI = ::GetDeviceCaps(dc, LOGPIXELSX);
const int yDPI - ::GetDeviceCaps(dc, LOGPIXELSY);
assert(xDPI == yDPI);
... | <p>It's possible for it to be different, but that generally only applies to printers. It can be safely assumed that the screen will always have identical horizontal and vertical DPIs.</p>
| <p>I've never seen a case where they're different, but the fact that there are two separate calls for it strongly suggests that they might be sometimes.</p>

<p>I'm currently using a UIImageView with an array of images to create a small looping animation sequence with about 20 images in there (at 320x480).

| <p>Put an entry in the registry on install. If, when the installer runs, the entry is there, then the program is already installed (or your user has hacked the registry to make the installer think it has been). If it's not, then you haven't installed it yet.</p>
| <p>If you don't want to put anything in the registry (due to admin rights or anything like that), you can simply check to see if the folders or files you install are present. Yes, this assumes you install to the same folder every time, but it's an option.</p>

<p>Is there any reason to avoid using <code>text-align: justify;</code>? </p>

| <p>Firstly, this is purely a design-related problem and solution. The design of your grid specifies if justifying text is needed. I think justify align alone has no major effect on usability. Bad typography that makes text illegible is what decreases usability. That said, make sure you have solid contrasts and a good ... | <p>I think it is perfectly OK on print, but it is clunky on most Web browsers, by lack of fine control of spacing and hyphenation. Typographers can even play slightly on letter spacing or font contraction in some cases, as pages/columns (at least in magazines) can be finely tuned.</p>

I don't think that the SAXReader is smart enough to stop when it gets to the end of the first document. Why is it necessary to have multiple documents in the same stream like this?</p>

<p>There is a conversion process that is needed when migrating Visual Studio 2005 web site to Visual Studio 2008 web application projects.</p>
<p>It looks like VS2008 is creating a .designer. file for every aspx when you right click on a file or the project itself in Solution Explorer and select 'Convert to Web Applic... | <p>They hold all the form designer stuff that used to go in the #Region " Web Form Designer Generated Code " section of the code. instead of putting it in the .aspx.vb file where people might edit it (mistakenly or not), it's been moved to a separate file, so that you don't have ever look at it.</p>

<p>For the part of your question about existing on a release build, it depends on what kind of web site you have. If you have a pre-compiled web site, then <em>none</em> of code files (.vb, .cs, etc) need to be deployed the server. They are compiled into .dlls (assemblies) and deployed tha... | 4,811 |

<p>You didn't include any interesting details, so here are a few guesses (because <em>of course</em> the mainframe normally gets sent <code>WM_SIZE</code> messages...):</p>

<p>I have never quite understood how/why I would use Maven modules (reactor builds).</p>

<p>I have a system (Ubuntu) with many processes and one (or more) have a memory leak. Is there a good way to find the process that has the leak? Some of the process are JVMs, some are not. Some are home grown some are open source.</p>
| <p>You can run the <code>top</code> command (to run non-interactively, type <code>top -b -n 1</code>). To see applications which are leaking memory, look at the following columns:</p>

I would normally suggest to grab a debugger/memory profiler like <a href="http://valgrind.org/" rel="nofollow noreferrer">Valgrind</a> and run the programs one after one in it. Soon or later you will find the program that leaks and can tell it the devloper or fix it yourself.</p>
