  • Is there a way to organize a icon collection to allow for easy searching?

    - by John M
    Is there any way of organizing a icon collection so that it easier to find needed icons? For example: the program needs a save icon there are 5 icons collections on your HD that have a save icon and there are 5 more collections that don't have a save icon (but you don't know that) do you browse through each icon collection? run a search (assumes files are named consistently)? Would it be ideal to have some sort of organized directory (printable?)?

  • Best way to use the same HTML on static web-pages

    - by John
    If you use dynamic pages like JSP or asp.net, you can have your page template included, and then content added. But what if you have no server-side component and all pages are just HTML/JS? You can of course create a template then copy it for each page, but then if you want to change something you risk having to modify every page, even if you put most styling in CSS properly. Are there any non-awful ways to do this? I could see that an iframe could be used to load the content into the central page but that sounds nasty. Does HTML provide any way to include a base file and add to it?

  • Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

    - by John Himmelman
    My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

ELSE: return cleaned_data Thanks

  • How can I set paperclip's storage mechanism based on the current Rails environment?

    - by John Reilly
    I have a rails application that has multiple models with paperclip attachments that are all uploaded to S3. This app also has a large test suite that is run quite often. The downside with this is that a ton of files are uploaded to our S3 account on every test run, making the test suite run slowly. It also slows down development a bit, and requires you to have an internet connection in order to work on the code. Is there a reasonable way to set the paperclip storage mechanism based on the Rails environment? Ideally, our test and development environments would use the local filesystem storage, and the production environment would use S3 storage. I'd also like to extract this logic into a shared module of some kind, since we have several models that will need this behavior. I'd like to avoid a solution like this inside of every model: ### We don't want to do this in our models... if Rails.env.production? has_attached_file :image, :styles => {...}, :storage => :s3, # ...etc... else has_attached_file :image, :styles => {...}, :storage => :filesystem, # ...etc... end Any advice or suggestions would be greatly appreciated! :-)

  • Maximized MFC window has dead region at the top

    - by John Calsbeek
    I'm trying to make a MFC window fullscreen whenever it is maximized. This window is being used to draw OpenGL content. So far it works fine—it fills the entire screen with the exception of the taskbar—but there's a dead black region at the top of the screen, 62 pixels in height. It's pretty darn close to the height of the Windows 7 taskbar, but it pretty much stays the same regardless of if the taskbar is on autohide or on a different side of the screen. When I get a CWind::OnSize callback, the height that is given is 988, which is 62 pixels short of the actual screen height (1050). I've tried to manually set the window height to 1050 with SetWindowPos, I've tried to give Windows the screen dimensions in CWnd::OnGetMinMaxInfo, and I've tried to give the screen dimensions to glViewport instead of the 988 pixels that I'm being given. None of these seem to work. I'm accomplishing the fullscreening with a call to… ModifyStyle(0, WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_SYSMENU | WS_CAPTION | WS_POPUP, 0); …in the SIZE_MAXIMIZED CWnd::OnSize callback, which works fine, except for this dead region. I don't know if it's an OpenGL thing or a Win32 thing or a MFC thing. The GetClientRect function for my window reports the false 988 height. The same OpenGL rendering code works fine in my Mac OS X build. Curiously enough, I have gotten the dead region to move around a bit when I play with the taskbar (autohiding it, moving it around the screen, etc.). I've gotten the dead area to shrink to about half—not sure if the other half went to the bottom of the window or not.

  • [Win32/MFC] Making group-boxes contain things

    - by John
    As I understand it, a group-box is just another control. Controls inside it are not owned by it, so unlike in Winforms, if you move a group-box the contained controls stay put. What would be the nicest way to address this? Just create your own data-structure mapping controls to 'container' group-boxes so that when the container is moved the children are automatically moved?

  • How can I view the all inherited url-resolution rules affecting a given directory?

    - by john.designop.us
    I work on two sites hosted on the same server, using the same CMS configurations and identical .htaccess files in their respective document roots. One site is letting me use the CMS's clean-url mode, and the other isn't. Site #2 functions fine in ?=messy-url mode, but when I turn clean urls on in the admin panel, and request a rewritten URL, I get a 404 error served before the CMS sees the request. I've contacted the server administrator, but he isn't inclined to provide support and the site owners are beholden to this hosting provider. I have shell access to the Linux-based server, and I can verify that mod_php and mod_rewrite are active, but I don't know what more I can do to troubleshoot this issue. Is there any way to identify directives upstream that may be differentiating the way http requests are handled by the two sites? Thanks!

  • WebDav alternatives? Win server 2003, win 7.

    - by John
    I have an internal web page that I have an iframe with the source pointing to a webdav folder. This allows the user to drag and drop a number of files on the iframe window which a button on the main page then kicks off a server side task to process the files. I am looking for an alternative that will allow me to drag a group of files and drop them onto a target area of a web page which will then upload them to the web server. Ideally this would be in ASP.Net 2,3 or 4. Any suggestions? TIA J

  • Javascript append to onClick event

    - by John Hartsock
    Guys I have the following Code which I know doesnt work correctly. Yes I know how to do this in JQuery but In this case I cannot use jquery. Please no jquery answers. <form> <input type="text" name="input1" onclick="alert('hello')"> <input type="text" name="input2"> <input type="text" name="input3"> </form> <script type="text\javascript"> window.onload = function () { var currentOnClick; for (var i = 0; i < document.forms[0].elements.length; i++) { currentOnClick = document.forms[0].elements[i].onclick; document.forms[0].elements[i].onclick = function () { if (currentOnClick) { currentOnClick(); } alert("hello2"); } } } </script> What Im trying to do is iterate through the form's elements and add to the onclick function. But due to the fact that in my last iteration currentOnClick is null this does not run as expected. I want to preserve each of the elements onclick methods and play them back in the new fuction Im creating. What I want: When input1 is clicked, alert "hello" then alert "hello2" When Input2 is clicked, alert "hello2" When Input3 is clicked, alert "hello2"

  • Why does my git push hang after successfully pushing?

    - by John
    On a newly set up ssh git repo, whenever I push, I get normal output like this: ? git push Counting objects: 15, done. Delta compression using up to 4 threads. Compressing objects: 100% (9/9), done. Writing objects: 100% (9/9), 989 bytes, done. Total 9 (delta 7), reused 0 (delta 0) It happens very quickly, and the changes are immediately available on the server repo. But the output hangs there for about a minute, and then finishes with: To [email protected]:baz.git c8c391c..1de5e80 branch_name -> branch_name If I control-c before it finishes, everything seems to continue to be normal and healthy, locally and remotely. What is it doing while hanging? Is something configured incorrectly on the server side?

  • Perl, Net::Traceroute::PurePerl return value

    - by John R
    This is a sub routine that I copied from CPAN. It works fine as it is when I run it from the command line. I have a similar function from Net::Traceroute that also works fine AND allows me to return the string with a SOAP call. The problem comes when I try to return the ~string(?) from the function below with a SOAP call. sub tr { use Net::Traceroute::PurePerl; my $t = new Net::Traceroute::PurePerl( backend => 'PurePerl', # this optional host => 'www.whatever.com', debug => 0, max_ttl => 30, query_timeout => 2, packetlen => 40, protocol => 'udp', # Or icmp ); $t->traceroute; $t->pretty_print; return $t; #print $t; } The output looks like a string except the last part of the string looks like this: 28 * * * 29 * * * 30 * * * Net::Traceroute::PurePerl=HASH(0x11fa6bf0) I don't know what is different about Net::Traceroute::PurePerl that won't allow me to return the value with SOAP since the Net::Traceroute version does allow me to return it with SOAP.

  • [MS-DOS] Read command-line parameters to .bat from file

    - by John
    I have a build.bat file which uses %1 internally... so you might call: build 1.23 I wanted it to read the parameter from a separate file, so I tried putting "1.23" in version.txt and doing: build < version.txt But it doesn't work. Isn't this how piping works? Is what I want possible and if so how?

  • Generating HTML Programmatically in C#, Targeting Printed Reports

    - by John Passaniti
    I've taken over a C# (2.0) code base that has the ability to print information. The code to do this is insanely tedious. Elements are drawn onto each page, with magic constants representing positioning. I imagine the programmer sitting with a ruler, designing each page by measuring and typing in the positions. And yes, one could certainly come up with some nice abstractions to make this approach rational. But I am looking at a different method. The idea is that I'll replace the current code that prints with code that generates static HTML pages, saves them to a file, and then launches the web browser on that file. The most obvious benefit is that I don't have to deal with formatting-- I can let the web browser do that for me with tags and CSS. So what I am looking for is a very lightweight set of classes that I can use to help generate HTML. I don't need anything as heavyweight as HTMLTextWriter. What I'm looking for is something to avoid fragments like this: String.Format("<tr><td>{0}</td><td>{1}</td></tr>", foo, bar); And instead take have this kind of feel: ... table(). tr(). td(foo). td(bar) Or something like that. I've seen lightweight classes like that for other languages but can't find the equivalent (or better) for C#. I can certainly write it myself, but I'm a firm believer in not reinventing wheels. Know anything like this? Know anything better than this?

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • Automatically update php loop with data pulled from database
