    I have an image path string stored in a database It goes like: img/uploads/imagename.jpg I have a controller: $this->image = new Image($wines->image) //this is assuming that I have a wines table with the image property $this->image->resize(60, 250, Image::AUTO) echo $this->image->render(); //the problem is nothing is rendered //Is there a better way of doing this? the image path that I am passing at the Image object //instantiation is the result of a query

  • Debugging CodeIgniters 404 errors

    - by Alex
    I'm having a nightmare uploading my site to the production server. The site runs fine locally and on a staging server (exactly the same server, settings as the production site). However when I deploy to production I'm getting a 404 error from CI. CodeIgniters 404 error pages are frustrating because it seems as if i can't access other libraries from them. How can I go about debugging the error? See which controller is trying to be called etc.

  • use viewengine only within certain area

    - by Daniel Powell
    Is it possible to use a custom view engine for a specific area only? I have tried public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Forms_default", "Forms/{client}/{controller}/{action}/{id}", new { client="Generic",action = "Index", id = UrlParameter.Optional } ); ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new ClientSpecificViewEngine()); } Within my area but this seems to be a site wide affect as I'm getting errors specific to the custom view engine when visiting pages outside the area.

  • Asp.Net MVC and Entity Framework Architecture

    - by Pino
    Hi, I'm working on a fairly large project at the moment and am currently in the planning stages. I've done a lot of reading into the various patterns suggested for development, somthing that has split the team at the moment is when using Entity Framework should the classes be passed through the applciation layers so that a view accepts an Entity Framework class or should these classes be mapped to BLL Classes and if so at which point (Controller or Library) should this be done? I'm interested in hearing some positives and negitives for each solutions.

  • iPhone - Tweak the UINavigationController to show a UINavigationBar made into IB

    - by Oliver
    Hello, I've build a UINavigationBar into Interface Builder, and I have a NavigationController into my app. I'd like to make the one use the other to work. Just to manage the bar into IB and let the controller use it as its view (and adding by itself the Back button if needed), or in another way to do the same thing, let the NavBar use the navcontroller to adjust its display. Do you see a way to do this ? If not, I really don't see the use of the NavigationBar proposed into IB.

  • How can I get a custom UITableView to automatically scroll to a selected text field?

    - by nornagon
    I have a UITableView, which I am controlling from a custom UIViewController. When the user clicks the 'add' button, I add a row to the UITableView with a text field in it, and make it the first responder. The problem is, when the bottom of the table is out of view (or hidden by the keyboard), the UITableView doesn't scroll to bring the text field into view. UITableViewController does this automatically, but my View Controller can't be a subclass of UITableViewController.

  • iPhone: How to Trigger the Loading of a View Using a UI Element in a Previous View

    - by Kevin Horvath
    I've been reading the Head First iPhone Development book and I understand how to get to a new view from a table but how exactly would I be able to get to a new view or view controller, by just simply pressing a button? Is that even possible? I mean there are some apps where you click a button, not a table cell and it loads a new view. How exactly is that done? If someone could help out a newbie it would be greatly appreciated!

  • Is there a way to use the OSX cocoa NSApplication method activateIgnoringOtherApps: to activate an a

    - by Michael Minerva
    This may be a dumb question but it seems like activateIgnoringOtherApps: may be the only way to activate an app using Cocoa. I have a java app that loads up a Cocoa app and I want the Cocoa app to be activated when this happens. The problem is I do not want to have to launch an intermediate app (some sort of controller) and use this app to activateIgnoringOtherApps: my other Cocoa app. Is there some way to use activateIgnoringOtherApps: to force my Cocoa app to become active?

  • USB windows xp final USB access issues

    - by Lex Dean
    I basically understand you C++ people, Please do not get distracted because I'm writing in Delphi. I have a stable USB Listing method that accesses all my USB devices I get the devicepath, and this structure: TSPDevInfoData = packed record Size: DWORD; ClassGuid: TGUID; DevInst: DWORD; // DEVINST handle Reserved: DWord; end; I get my ProductID and VenderID successfully from my DevicePath Lists all USB devices connected to the computer at the time That enables me to access the registry data to each device in a stable way. What I'm lacking is a little direction Is friendly name able to be written inside the connected USB Micro chips by the firmware programmer? (I'm thinking of this to identify the device even further, or is this to help identify Bulk data transfer devices like memory sticks and camera's) Can I use SPDRP_REMOVAL_POLICY_OVERRIDE to some how reset these polices What else can I do with the registry details. Identifying when some one unplugs a device The program is using (in windows XP standard) I used a documented windows event that did not respond. Can I read a registry value to identify if its still connected? using CreateFileA (DevicePath) to send and receive data I have read when some one unplugs in the middle of a data transfer its difficult clearing resources. what can IoCreateDevice do for me and how does one use it for that task This two way point of connection status and system lock up situations is very concerning. Has some one read anything about this subject recently? My objectives are to 1. list connected USB devices identify a in development Micro Controller from everything else send and receive data in a stable and fast way to the limits of the controller No lock up's transferring data Note I'm not using any service packs I understand everything USB is in ANSI when windows xp is not and .Net is all about ANSI (what a waste of memory) I plan to continue this project into a .net at a later date as an addition. MSDN gives me Structures and Functions and what should link to what ok but say little to what they get used for. What is available in my language Delphi is way over priced that it needs a major price drop.

Is there a way to Json serialize a SiteMap, or indeed any object that has children of the same type?

  • NSMutableArray: count is a method or a property?

    - by Rafael Oliveira
    I want to verify if I'm in the last cell of the UITable. Should I use a NSInteger property in my controller and store the value of the count of the data (it's an NSMutableArray) that populates the table? I'm asking because I don't know if count iterates over all objects of the array to count or if it only gets me a value of a count property. What would be better ? store the value: myCount = [myArray count] use directly: [myArray count] store numberOfRows: myCount = numberOfRowsInSection:[indexPath 0] use numberOfRows directly: numberOfRowsInSection:[indexPath 0]

  • WPF Binding when setting DataTemplate Programically

    - by Daniel
    Hello, I have my little designer tool (my program). On the left side I have TreeView and on the right site I have Accordion. When I select a node I want to dynamically build Accordion Items based on Properties from DataContext of selected node. Selecting nodes works fine, and when I use this sample code for testing it works also. XAML code: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> <layoutToolkit:AccordionItem Header="Controller Info"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </layoutToolkit:AccordionItem> </layoutToolkit:Accordion> C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; //e.NewValue is a class that contains Name property } } } But the problem occurs when I'm trying to achive this using DateTemplate and dynamically build AccordingItem, the Binding is not working: <layoutToolkit:Accordion x:Name="accPanel" SelectionMode="ZeroOrMore" SelectionSequence="Simultaneous"> </layoutToolkit:Accordion> and DateTemplate in my ResourceDictionary <DataTemplate x:Key="dtSceneNodeContent"> <StackPanel Orientation="Horizontal" DataContext="{Binding}"> <TextBlock Text="Content:" /> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </DataTemplate> and C# code: private void treeSceneNode_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (e.NewValue != e.OldValue) { ResourceDictionary rd = new ResourceDictionary(); rd.Source = new Uri("/SilverGL.GUI;component/SilverGLDesignerResourceDictionary.xaml", UriKind.RelativeOrAbsolute); if (e.NewValue is SceneNode) { accPanel.DataContext = e.NewValue; AccordionItem accController = new AccordionItem(); accController.Header = "Controller Info"; accController.ContentTemplate = rd["dtSceneNodeContent"] as DataTemplate; accPanel.Items.Add(accController); } else { // Other type of node } } } I really need help with this issue. Thanks for any support. Daniel
