• CakePHP: How do I change page title from helper?

  - by Zeta Two

  Hello! I'm using a helper for static pages to add a part to the title on every page. Currently I have the following code at the top of every static page: <?php $this->set('title_for_layout', $title->output('Nyheter')); ?> The purpose of $title-output is to append " :: MY WEB SITE NAME". This works fine, but for simplicity I would rather just call: $title->title('Nyheter'); At the top of every page to set the title. The problem is that I can't call $this-set() from within the helper. Is there a way to something like this or am I completely on the wrong path here?

• Eclipse buildpath automatically taking all JARs of a internal directory

  - by Niko

  How do I configure my project buildpath to have a set of .jar files located in the same directory automatically included in the buildpath ? Meaning that adding a new .jar file to this directory (and refreshing the project) updates the buildpath ? Rem : I am not working in a Webapp but in a standalone Java app. I know that it is possible in a Dynamic Web Project to have all the .jars located in WEB-INF/lib to be included in the build path. Is it possible to do kind of the same include but in standalone app ? I am using Eclipse 3.4

• Launch Activity with Intent Filter on Right Time

  - by user511853

  Hi. I want to launch my own media player application when I want to watch a video from Youtube. When I write android:scheme="http" and android:host="m.youtube.com" it is OK. But, it asks everywhere in m.youtube.com to open my app. So, it gets annoying. I tried to use pathPattern, pathPrefix and path to solve this but I didn't get ahead. All I want is clearly this: When the link is like "http://m.youtube.com/index?desktop_uri=%2F%gl=US#" the intent filter shouldn't launch my app. When the link is like "http://m.youtube.com/index?desktop_uri=%2F&gl=US#/watch?xl=xl_blazer&v=k3Cdqx1qFX8" my application should be launched. Is there anyone that can help me?

• Customize iphone app for different clients

  - by gnibbler

  I have an existing app that needs to be compiled for different clients Each client requires their own icon and splash screen. I would also like to be able to conditionally include various features depending whether the particular client requires them or not. I have tried setting up different targets for each client, but not having much luck so far. The different resources with the same name, but a different path keep getting mixed up. Ideally I would like to be able to build an app by duplicating another client that is similar and then just make the minimum number of changes to create the app for the new client. What is the best way to set this app up?

• Design best practice - best way to handle user selection

  - by user1457227

  I'm an experienced developer (WPF) moving over to Android development. My question: an app I am developing allows the user to browse their local storage (such as SDCARD) and select a file. Now, should I simply create a new Activity (after the user has made a selection) to handle what I want to have the app do with that chosen file, -or- is the better approach to pass the path/name of the selected file back to the main Activity and let IT launch the next Activity? In other words, is the better practice to have the main Activity launch other (support) activities, or is it perfectly ok and normal to have one activity chain to another and on and on? Thanks!

• Getting differences between collections in LINQ

  - by dotnetdev

  Hi, I have a collection of image paths, and a larger collection of Image objects (Which contain a path property). I have the code to check for any matching images, but if there are supposed to be four matching image paths (as that is how many are in the first collection), and there is less than this, how can I get the missing one without writing loops? List<string> ImagesToCheck = new List<string>() { "", "s", "ssdd" }; IEnumerable<HtmlImage> Images = manager.ActiveBrowser.Find.AllControls<HtmlImage>(); var v = from i in Images where ImagesToCheck.Any(x => x == i.Src) select i; if (v.Count() < 3) { } So I need to get the items which are not in the collection titled v, but are in ImagesToCheck. How could I do this with LINQ? Thanks

• Suggest encoding which removes slashes which I can use as the format for REST-style URL-paramteters

  - by Binary255

  Given a path to a REST style URL: http://site.com/rest/customer/foo/robot/bar/1 When you GET it, it returns a PDF to the foo-customer containing page 1 of the bar-URL. While foo is the name of the customer bar is an URL. The URL usually contains slashes and might look something like this: http://anothersite.com/interestingarticle.html As REST URL's separate arguments by slashes I can't just put it into the REST URL above. Which encoding should I use? I can't use Base 64 as it utilizes the slash as well. As a technical note I will encode the URL in a .NET-application and decode it in PHP.

• CMD Execption Handling C/C++

  - by ciyo

  I will use some CMD commands in my program and these commands might throw some exceptions. And as you know, when an exception accours, CMD writes its own error message the screen. But, I want to write my own error message. My question is this: Is there a way to block CMD messages and write only my own error messages? P.S. This is not a complex program. It executes CMD commands using System(). Example: Let's say, the user can rename and copy any files in the program. As you know, if the user does not enter file's path properly, an error message is showed on the screen. And I want that this error message never appears on the screen. Only my own error message is showed. Thank you!

• Is it possible to use os.walk over SSH?

  - by LeoB

  I'm new to Python so forgive me if this is basic, I've searched but can't find an answer. I'm trying to convert a Perl script into Python (3.x) which connects to a remote server and copies the files in a given directory to the local machine. Integrity of the transfer is paramount and there are several steps built-in to ensure a complete and accurate transfer. The first step is to get a complete listing of the files to be passed to rsync. The Perl script has the following lines to accomplish this: @dir_list = `ssh user@host 'find $remote_dir -type f -exec /bin/dirname {} \\;'`; @file_list = `ssh user@host 'find $remote_dir -type f -exec /bin/basename {} \\;'`; The two lists are then joined to create $full_list. Rather than open two separate ssh instances I'd like to open one and use os.walk to get the information using: for remdirname, remdirnames, remfilesnames in os.walk(remotedir): for remfilename in remfilesnames: remfulllist.append(os.path.join(remdirname, remfilename)) Thank you for any help you can provide.

• Bitmap manipulation as a referenced object

  - by John Maloney

  I am working with a Bitmap object that I add annotations or copyright material to the image and then return the modified bitmap. My problem is that the Bitmap won't hold the changes made to it as it moves along the chain. I am treating it as a reference type and would assume that as it gets passed to each class it would carry the changes made to it. I have verified that the code inside of the MarkImage() classes does function, but which ever one gets called last is the one that has changes. Public Shared Function GetImage(ByVal imageDef As IImageDefinition) As Bitmap Dim image As Bitmap = Drawing.Image.FromFile(imageDef.Path) If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutCopyright) Then image = New MarkCopyrightImage(image).MarkImage() End If If Not imageDef.Authorization.IsAllowed(AuthKeys.CanViewWithoutAnnotations) Then image = New MarkAnnotateImage(image).MarkImage() End If Return image End Function How do I write changes to a bitmap object and then pass that object to another class while maintaining the changes? Answers in C# or VB are fine? Thanks

• Selecting the first row out of many sql joins

  - by IcedDante

  Alright, so I'm putting together a path to select a revision of a particular novel: SELECT Catalog.WbsId, Catalog.Revision, NovelRevision.Revision FROM Catalog, BookInCatalog INNER JOIN NovelMaster INNER JOIN HasNovelRevision INNER JOIN NovelRevision ON HasNovelRevision.right = NovelRevision.obid ON HasNovelRevision.Left=NovelMaster.obid ON NovelMaster.obid = BookInCatalog.Right WHERE Catalog.obid = BookInCatalog.Left; This returns all revisions that are in the Novel Master for each Novel Master that is in the catalog. The problem is, I only want the FIRST revision of each novel master in the catalog. How do I go about doing that? Oh, and btw: my flavor of sql is hobbled, as many others are, in that it does not support the LIMIT Function.

• Reloading Rails Directories on Change for Development, Not in Lib

  - by yar

  I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

• How do I pass objects through a _url based on a routing in rails?

  - by Angela

  I want to pass the attributes associated with two objects into a path created from a route. In this case, the _url is skip_contact_letter_url. contact_letter and letter are passed through a render partial. The clip below resides in the partial. <%= link_to_remote "Skip Letter Remote #{contact_letter}", :url => skip_contact_letter_url(contact_letter, letter), :update => "update-area-#{contact_letter.id}-#{letter.id}" %> <span id='update-area-<%="#{contact_letter.id}-#{letter.id}"%>'> </span> The route I created looks like this: map.resources :contact_letters, :member => {:skip => :post} And the controller looks like this: def skip @contact_letter = ContactLetter.new(params[:all]) @contact_letter.status = "skipped" @contact_letter.date_sent = Date.today #@contact_letter.date_created = Date.today if @contact_letter.save render :text => 'This letter was skipped!' end end When I look at the console, none of the parameters from contact_letter or letter get passed through.

• Display local image in iPhone HTML mail

  - by Sjakelien

  Hello there, In my app, I am composing an HMTL email message with the 3.0+ MFMailComposeViewController. To do this, I created an HTML file, with some placeholders. In my code, I read the HTML file, and with replaceOccurrencesOfString, I replace the placeholders with data from the app. In that way, I compose the body of the email I want to send out. This is all working very nicely, except for the fact, that in my HTML file, I have an <img src='imageplaceholderpath' /> tag. Somehow, I cannot figure out, with what I should replace this imageplaceholderpath, in order to refer to an image that resides in my app. Is this a valid approach at all, and if so, what would be the syntax/logic behind the path I should put there? I do appreciate your insights! Regards Sjakelien

• Parse xml file with same tag multiple times iphone sdk

  - by neha

  Hi all, In my application, I have a tag multiple times. I'm using xml parser. I'm taking a corresponding element with similar name as the one in xml file in my class. So in case of: <photo>abc</photo> <photo>def</photo> What I get in photo element of my class is the second element i.e def, as the first one gets overwritten as there's only one photo element in my class. My question is am I wrong in taking similar elements in class as in case of xml? Is there any better method or a better parser? Or I'm on right path and have to do this manually by setting some flags etc? Thanx in advance.

• Stuck on solving the Minimal Spanning Tree problem.

  - by kunjaan

  I have reduced my problem to finding the minimal spanning tree in the graph. But I want to have one more constraint which is that the total degree for each vertex shouldnt exceed a certain constant factor. How do I model my problem? Is MST the wrong path? Do you know any algorithms that will help me? One more problem: My graph has duplicate edge weights so is there a way to count the number of unique MSTs? Are there algorithms that do this? Thank You. Edit: By degree, I mean the total number of edges connecting the vertex. By duplicate edge weight I mean that two edges have the same weight.

• need a code snippet to find all *.html under a folder in nodejs

  - by Nicolas S.Xu

  I'd like to find all *.html files in src folder and all its sub folders using nodejs. What is the best way to do it? var folder = '/project1/src'; var extension = 'html'; var cb = function(err, results) { // results is an array of the files with path relative to the folder console.log(results); } // This function is what I am looking for. It has to recursively traverse all sub folders. findFiles(folder, extension, cb); I think a lot developers should have great and tested solution and it is better to use it than writing one myself.

• Separate one-off code paths

  - by DeadMG

  I'm implementing an application with different code paths that shall be chosen once at startup and then fixed forevermore for that execution- for example, choosing D3D11 or D3D9 rendering path. Obviously I don't want to duplicate all my other code. Is run-time inheritance (no virtual inheritance) a fair solution? I don't want to waste a bunch of performance making virtual lookups when the type was fixed long ago. Not just that, but it makes me nervous that the functions can't be inlined and whether or not it affects RVO and NRVO and such. Am I just being over-concerned about this?

• Recommended place for pre-translated Zend Framework resources

  - by Exception e

  Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?
