• Displaying Photos on iPhone

  - by Bjorn S.

  Hi all, I'm working on an iPhone app and I need to be able to display images to users. I have already gotten the code that takes the photo and stores it into the filesystem working well. Now I just need to figure out how to display the image. I've looked at the Three20 project I've read about on a few of the posts here, but it seems a bit cumbersome and like an extra dependency to import link and combine all of the Three20 library into my little app. Are there any other ways or a more streamlined library that will let me display photos to my users? Thanks! B.

• Combining Two Models in Rails for a Form

  - by matsko

  Hey Guys. I'm very new with rails and I've been building a CMS application backend. All is going well, but I would like to know if this is possible? Basically I have two models: @page { id, name, number } @extended_page { id, page_id, description, image } The idea is that there are bunch of pages but NOT ALL pages have extended_content. In the event that there is a page with extended content then I want to be able to have a form that allows for editing both of them. In the controller: @page = Page.find(params[:id]) @extended= Extended.find(:first, :conditions = ["page_id = ?",@page.id]) @combined = ... #merge the two somehow So in the view: <%- form_for @combined do |f| % <%= f.label :name % <%= f.text_field :name % ... <%= f.label :description % <%= f.text_field :description % <%- end This way in the controller, there only has to be one model that will be updated (which will update to both). Is this possible?

• Setting up phpstorm 4 with XAMPP on Windows 7

  - by stirredo

  I need help setting up phpstorm (4.0) with XAMPP which is at the default location c:\htdocs. I create all my projects at c:\htdocs\projectname. Here are the things I have already done: Setup the PHP interpretator by going to settings and then PHP (main menu) Go to PHP Servers and then To setup run configuration I have the done the following: Now when I run using the above configuration it just takes me to localhost in my browser, instead of the file I am editing (http://localhost instead of localhost/myproject/myfile.php). What am I missing? I read the help topics of phpstorm and googled a lot but still couldn't figure it out.

• VS2008: Disable asking whether to reload files changed outside the IDE

  - by SealedSun

  Hi, I have a Visual Studio 2008 project where some code files are generated with each build (a parser, integrated via MSBuild aka editing the *.csproj file). VS does not know about the generated nature of these files (i.e. they are not the result of a "Custom Tool). So they "change" with every build, naturally. And VS2008 asks me after every build if I would like to reload those files: This file has been modified outside the source Do you want to reload it? That would be ok if I had one of those files opened and in front of me, but I get these modal dialogs even with none of the code files opened. So my question is: Is there a way to disable this dialog, per project, per solution or globally? Thanks!

• (My)SQL performance: updating one field vs many unneccesary fields

  - by changokun

  i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

• What tech stack/platform to use for a project?

  - by danny z

  Hey guys, This is a bit of a weird meta-programming question, but I've realized that my new project doesn't need a full MVC framework, and being a rails guy, I'm not sure what to use now. To give you a gist of the necessary functionality; this website will display static pages, but users will be able to log in and 'edit their current plans'. All purchasing and credit card editing is being handled by a recurring payment subscriber, I just need a page to edit their current plan. All of that will be done through (dynamic) XML API calls, so no database is necessary. Should I stick with my typical rails/nginx stack, or is there something I could use that would lighten the load, since I don't need the Rails heft. I'm familiar with python and PHP but would prefer not to go that route. Is Sinatra a good choice here? tl;dr: What's a good way to quickly serve mostly static pages, preferably in Ruby, with some pages requiring dynamic XML rendering?

• Zend Dd Rowset getting parent row

  - by simple

  I am wondering about using the abstraction in Zend Db RowSet instead of joins, is it possible for instance I am able to get some info from parent table as in here /** * Get default photo info (path , description) */ public function getDefaultPhotoInfo($userdId){ $select = $this->select($this) ->where('id=?', $userdId); $rowset = $this->fetchAll($select); $current = $rowset->current(); $res = $current->findParentRow('UserPhotos', 'Avatar'); if(isset($res)){ return $res->toArray(); } } How can I use Rowset abstraction to get this logic working table( id, pic_path,) table_translation(id, table_id, lang_id, pic_title); the above is representation of two tables , the idea is to get the info from both table specifying the lang_id , it is easy with joins but can I do it with the abstraction of Db Rowset ?

• Is there a decent JSON editor around?

  - by al4nis

  I'm looking for a JSON editor that is able to do syntax checking and outline view. Browser-based editors are not an option as they are clumsy for editing lots of local files. Eclipse plug-in would be ideal, but I would be happy with anything that works. I found only two so far, those in Aptana Studio Pro and Spket IDE (both available as plug-ins for Eclipse). While they have decent outline views, their syntax checking doesn't catch most of the common errors (like missing commas or braces) which makes them almost useless.

• UIPopover Sizing

  - by Echilon

  I have a UIPopoverController which I'm trying to show from a UIBarButtonItem in a navigation bar. Despite setting the resizing mask for the tableview inside the popover's content viewController, it takes up the whole height of the screen. The only thing which has any effect on the content size is menuPopover.contentViewController.view setFrame:CGRect. I'm using the code below to show the popover inside the left hand side of a UISplitViewController // menuPopover and editVc are properties on the parent viewController menuPopover = [[UIPopoverController alloc] initWithContentViewController:editVc]; [menuPopover presentPopoverFromBarButtonItem:btnMenu permittedArrowDirections:UIPopoverArrowDirectionAny animated:true]; [menuPopover setPopoverContentSize:CGSizeMake(400, 500) animated:true]; [menuPopover.contentViewController.view setFrame:CGRectMake(0,0,400, 500)]; Yet this is what I'm seeing. The arrow shows where the menu button was which showed the popover: http://imageshack.us/photo/my-images/545/screenshot20120312at191.png/ It's as though the content view is just expanding vertically.

• Linq to SQL EntitySet Records causing duplicate insertion

  - by Savvas Sopiadis

  In a WPF application i'm using Linq to SQL in a multi tier application. (This is an archailogy photo filing application), so every excavation has its corresponding Pictures, thus a one-to-many relationship. This relationship is correctly created by SQLMetal (which i'm using to create the POCOs). So here is the situation i 'm having trouble with: Saving changes (either of new or altered objects) is done through UnitOfWork() pattern this way: using (IUnitOfWork unitOfWork = UnitOfWork.Begin()) { //if this is a new record if (SelectedExcavation.excavation.ExcavationId == 0) { IsNewRecord = true; excavService.Add(SelectedExcavation.excavation); } //send the actual changes to the dbms unitOfWork.Commit(); } Everything works fine! BUTTTT!!! Whenever a record gets updated which has (already at least one ) corresponding Picture Record: 1) a new Excavation Record is inserted 2) the current Excavation Record gets updated 3) the previous Picture Record gets its Id changed to the newly created ExcavationId What is going on under the hood? Does Linq to SQL not handle such simple update scenarios? Thanks in advance

• Java/swing: console component?

  - by Jason S

  I am looking for a component I can use in Swing that acts as a GUI console which has a text area with scrollbars that can be set to a particular font has an InputStream and an OutputStream that a host application can obtain accepts keyboard input, prints it onto the end of the console text, and sends that input to the InputStream prints the OutputStream text to the end of the console has some kind of FIFO-ish property whereby the amount of text displayed in the console can be limited by automatically discarding the oldest text, when appropriate allows copy (but not cut or paste or any other editing) of the console text to the system clipboard This is kind of like the Console tab in Eclipse. Are there any good libraries that provide this?

• Any editors to visually modify Wix templates?

  - by user1632018

  I have tried wixedit and sharp develop and from what I can tell they do not allow you to visually modify the premade templates with a designer. They only allow you to create your own customized dialogs that you can design yourself. So I am wondering if there is any editors that you can visually modify the design of these templates, especially the mondo template with a point and click editor. I have also tried SharpSetup and it looks promising how you can design the interface in visual studio, although since I don't know much about editing wix I am having a hard time comming up with the wix code to make it work.

• Rails HABTM Scoping to current subdomain

  - by Rabbott

  I have the following associations: class User < ActiveRecord::Base has_and_belongs_to_many :brands, :join_table => 'brands_users' has_and_belongs_to_many :companies, :join_table => 'companies_users' end class Brand < ActiveRecord::Base belongs_to :company has_and_belongs_to_many :users, :join_table => 'brands_users' end class Company < ActiveRecord::Base has_and_belongs_to_many :users, :join_table => 'companies_users' has_many :brands, :order => :name end While editing a user I am using the checkbox list of brands. So that I can assign users 'access' to brands, the brands that show up are only the brands that belong to the current company (defined by the subdomain [using subdomain_fu]). The problem I am running into is that when using the default HABTM functionality and the checkbox list, upon save, Rails removes ALL user-brand associations, then re-adds just the ones for the form I just submitted.. How do I scope that to only remove associations of brands who belong to the current company, defined in the subdomain?

• How can I create an .xls file with a readwrite password from Delphi

  - by dummzeuch

  I know that it is possible to create .xls files from Delphi using ADO, OLE automation with Excel and even using several commercial libraries. My requirement now is not just creating a new .xls file and adding data to it but in addition protecting it with a password against editing. I guess this would be possible using OLE automation but that would require an Excel installation on the computer and also add all the potential hassle of OLE automation which I would like to avoid. Does any of the other solutions provide the option of password protecting the file? (Yes, I know this is far from secure, but the customer requests it. Just in case it matters: I am using Delphi 2007.)

• Surely there is a better grid than DataGrid for the .NET Compact Framework...

  - by PavelR

  Having spent a couple of days wrestling with DataGrid in .NET CF, especially controlling the look and feel, I'm looking for alternatives. I don't mind purchasing a solution. I'm looking for Redistributable to our enterprise customers. We control the hardware so it doesn't have to work perfectly on every device. Display strings and numbers in columns with headings. Scrollable, but no paging. Don't row editing. Need to add and delete rows. User re-sizable column widths, and a way to persist that. Work with .NET CF 2.0 or 3.5 on Windows CE 6.0 Any suggestions on grids or toolkits?

• Looking for a good Dynamic Imaging Solution

  - by user151289

  I work for a small E-Commerce shop and we are looking for a process that will handle resizing our product images dynamically. Currently our designers take high resolution photos, either provided by the manufactures or created in house, and alter them to fit various pages on our site. The designers are constantly resizing, cropping, altering compression levels, etc., of each product photo to fit the needs of the business. Being that our product line is updated frequently, this becomes a monotonous task. Abobe Scene7 does exactly what we are looking to do and the images are served up from a CDN. Unfortunately we found it to be too expensive. I'm curious to learn how others handle this process at their organizations. Does anyone know of any good 3rd party tools or other SAAS providers that can handle performing some basic image manipulation and serving them on the fly?

• snipMate only working on empty buffer?

  - by JesseBuesking

  I'm attempting to use snipMate with sql files, however it doesn't seem to work when editing an existing file. If I create a new empty buffer (no file; e.g. launch gvim from the start menu), and set the filetype to sql (:set ft=sql), it works. However, if I then try to open a sql file (e.g. :e c:\blah.sql) and edit it, snipMate no longer works. What gives!? Setup: gvim vim 7.3 Windows 7 snipMate 0.84 Also, I do in fact have filetype plugin on in my .vimrc file. edit Apparently if I open an empty buffer, set the filetype to sql, then save to file using w c:\blah.sql, I now have a sql file open AND snipMate continues to work. edit Here's a gist of my current .vimrc in case it helps: https://gist.github.com/3946877

Now you have to navigate away from the cell in order to have the property updated. It's a checkbox. It can't be in the middle of editing like a textbox can... Any help would be appreciated. /J
