  • Create a Gallery With Drupal and Thickbox

    Powerful features and special effects are not something that only big websites with plenty of cash to burn can afford. In fact, most of the neat design features you see nowdays are pretty easy to get right - some with practically no programming required. Let's look at how to create a basic image gallery using Drupal, Views and Thickbox.

    - by Scarface
    Hey guys I am pretty new to pdo so I basically just put together a simple connection class using information out of the introductory book I was reading but is this connection efficient? If anyone has any informative suggestions, I would really appreciate it. class PDOConnectionFactory{ public $con = null; // swich database? public $dbType = "mysql"; // connection parameters public $host = "localhost"; public $user = "user"; public $senha = "password"; public $db = "database"; public $persistent = false; // new PDOConnectionFactory( true ) <--- persistent connection // new PDOConnectionFactory() <--- no persistent connection public function PDOConnectionFactory( $persistent=false ){ // it verifies the persistence of the connection if( $persistent != false){ $this->persistent = true; } } public function getConnection(){ try{ $this->con = new PDO($this->dbType.":host=".$this->host.";dbname=".$this->db, $this->user, $this->senha, array( PDO::ATTR_PERSISTENT => $this->persistent ) ); // carried through successfully, it returns connected return $this->con; // in case that an error occurs, it returns the error; }catch ( PDOException $ex ){ echo "We are currently experiencing technical difficulties. We have a bunch of monkies working really hard to fix the problem.

  • Loading different portrait/landscape UIViews

    - by Tronic
    Hi, I have following View COntroller structure: ScrollViewController LandscapeViewController PortraitViewController Each with its own .nib The app starts in landscape mode where many landscape views are added to a scrollview. Each landscape view has its specific portrait view, so I have to assign like ID's to each of this views. Can you tell me, how I can load the specific portrait view for each landscape view when rotating the device? Do I have to make two scroll views? One for landscape, one for portrait? Or is it possible to just scroll through the landscape scrollview an load just one portrait view with the right content based on an ID? How could I implement that? The data comes from a property list. Thanks in advance!

  • Better to combine & minify javascript or use Google CDN?

    - by jessegavin
    I am building a site which currently uses javascript from several sources: Group 1: Google Maps API v3 (hosted by Google) Group 2: jQuery & swfobject (hosted on Google CDN) Group 3: Several jQuery plugins and non-jquery javascript files (hosted on my server) I am using Justin Etheredge's tool SquishIt to combine and minify all the javascript files that are hosted on my server (group 3). I am wondering if the site would 'feel' faster to users if I were to host the files in (group 2) locally so that they can be combined with all the other files in (group 3) and requiring only one HTTP request for groups 2 & 3. This would mean that I don't get the benefits of the Google CDN however. Does anyone have any advice on this matter?

  • Servlet File Upload Memory Consumption

    - by Scott
    Hi, I'm using a servlet to do a multi fileupload (using apache commons fileupload to help). A portion of my code is posted below. My problem is that if I upload several files at once, the memory consumption of the app server jumps rather drastically. This is probably OK if it were only until the file upload is finished, but the app server seems to hang on to the memory and never return it to the OS. I'm worried that when I put this into production I'll end up getting an out of memory exception on the server. Any ideas on why this is happening? I'm thinking the server may have started a session and will give the memory back after it expires, but I'm not 100% positive. if(ServletFileUpload.isMultipartContent(request)) { ServletFileUpload upload = new ServletFileUpload(); FileItemIterator iter = upload.getItemIterator(request); while(iter.hasNext()) { FileItemStream license = iter.next(); if(license.getFieldName().equals("upload_button") || license.getName().equals("")) continue; //DataInputStream stream = new DataInputStream(license.openStream()); InputStream stream = license.openStream(); ArrayList<Integer> byteArray = new ArrayList<Integer>(); int tempByte; do { tempByte = stream.read(); byteArray.add(tempByte); }while(tempByte != -1); stream.close(); byteArray.remove(byteArray.size()-1); byte[] bytes = new byte[byteArray.size()]; int i = 0; for(Integer tByte : byteArray) { bytes[i++] = tByte.byteValue(); } Thanks in advanced!!

  • Force VSProps settings to override project settings

    - by Steve
    I have a vsprops file that defines the optimizations all of our projects should be built with for Visual Studio 2008. If I set the properties for the project to "inherit from parent of project defaults" it works, and fills them in the vcproj file. However, this doesn't protect me from a developer checking in a project file that changes the optimizations. In this case, the project settings are used over the vsprops settings. I need to make it so that vsprops always takes precedence over what is in the vcproj file. Is this possible? Other workarounds are also welcome.

  • Varnish configuration to only cache for non-logged in users

    - by davidsmalley
    I have a Ruby on Rails application fronted by varnish+nginx. As most of the sites content is static unless you are a logged in user, I want to cache the site heavily with varnish when a user is logged out but only to cache static assets when they are logged in. When a user is logged in they will have the cookie 'user_credentials' present in their Cookie: header, in addition I need to skip caching on /login and /sessions in order that a user can get their 'user_credentials' cookie in the first place. Rails by default does not set a cache friendly Cache-control header, but my application sets a "public,s-max-age=60" header when a user is not logged in. Nginx is set to return 'far future' expires headers for all static assets. The configuration I have at the moment is totally bypassing the cache for everything when logged in, including static assets — and is returning cache MISS for everything when logged out. I've spent hours going around in circles and here is my current default.vcl director rails_director round-robin { { .backend = { .host = "xxx.xxx.xxx.xxx"; .port = "http"; .probe = { .url = "/lbcheck/lbuptest"; .timeout = 0.3 s; .window = 8; .threshold = 3; } } } } sub vcl_recv { if (req.url ~ "^/login") { pipe; } if (req.url ~ "^/sessions") { pipe; } # The regex used here matches the standard rails cache buster urls # e.g. /images/an-image.png?1234567 if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.cookie; lookup; } else { if (req.http.cookie ~ "user_credentials") { pipe; } } # Only cache GET and HEAD requests if (req.request != "GET" && req.request != "HEAD") { pipe; } } sub vcl_fetch { if (req.url ~ "^/login") { pass; } if (req.url ~ "^/sessions") { pass; } if (req.http.cookie ~ "user_credentials") { pass; } else { unset req.http.Set-Cookie; } # cache CSS and JS files if (req.url ~ "\.(css|js|jpg|jpeg|gif|ico|png)\??\d*$") { unset req.http.Set-Cookie; } if (obj.status >=400 && obj.status <500) { error 404 "File not found"; } if (obj.status >=500 && obj.status <600) { error 503 "File is Temporarily Unavailable"; } } sub vcl_deliver { if (obj.hits > 0) { set resp.http.X-Cache = "HIT"; } else { set resp.http.X-Cache = "MISS"; } }

  • What is the return type for a anonymous linq query select? What is the best way to send this data ba

    - by punkouter
    This is a basic question. I have the basic SL4/RIA project set up and I want to create a new method in the domain service and return some data from it. I am unsure the proper easiest way to do this.. Should I wrap it up in a ToList()? I am unclear how to handle this anonymous type that was create.. what is the easiest way to return this data? public IQueryable<ApplicationLog> GetApplicationLogsGrouped() { var x = from c in ObjectContext.ApplicationLogs let dt = c.LogDate group c by new { y = dt.Value.Year, m = dt.Value.Month, d = dt.Value.Day } into mygroup select new { aaa = mygroup.Key, ProductCount = mygroup.Count() }; return x; // return this.ObjectContext.ApplicationLogs.Where(r => r.ApplicationID < 50); } Cannot implicitly convert type 'System.Linq.IQueryable<AnonymousType#1>' to 'System.Linq.IQueryable<CapRep4.Web.ApplicationLog>'. An explicit conversion exists (are you missing a cast?) 58 20 CapRep4.Web

  • Changing stylesheet href with jQuery doesn't quite work

    - by Michael Itzoe
    I'm creating a web app that user will be accessing in the field, so they'd like to be able to manually toggle the styles from light to dark depending on the ambient lighting. I'm using jQuery. I added an id attribute to my stylesheet, then created a button using the toggle() event, in which I change the href attribute to the CSS file I want. The CSS file has several @import directives as I split the styles into several files for maintainability. My problem is only the main CSS file is being applied. I tried using the absolute path in the @import directives, but no luck. Is there a fix here I'm missing, or do I have to inlcude everything in a single CSS file? Edit: Apprently this is only a problem in IE8, works fine in Chrome and Firefox. Unfortunately, my client wants only IE8. Looks like this is a duplicate of this question.

  • Fixed background on iPhone Safari

    - by cannyboy
    iPhone Safari seems to have some sort of problem whereby a page with css like this: body { background: #000 url(fixedimage.png) fixed repeat-x; } ...doesn't actually lead to a fixed image. It scrolls as the user scrolls. I've seen plenty of people kvetching about this on the internets, but no real solution. Does anyone have any ideas?

  • F# "if" expression question

    - by Here
    Hi, I test some simple F# code for "if" expression, but the result is unexpected for me: > let test c a b = if c then a else b;; val test : bool -> 'a -> 'a -> 'a However > test true (printfn "a") (printfn "b");; a b val it : unit = () I'd expect only "a" is printed out but here I got both "a" and "b". I wonder why it comes out this way? Thanks!
