• IOC Container that can target .NET Framework Client Profile?

  - by Rox Wen

  On our current WPF project, we've been performing dependency injection using the Ninject IOC tool. We want to target the .NET Framework Client Profile for a better download/install experience. The problem is that Ninject seems to reference libararies such as System.Web which are NOT in the Client Profile. Can anyone recommend an IOC container that can target the .NET Framework Client Profile (3.5 or 4) ?

• C# CodeDom - making project's forms accessible for scripts.

  - by michal

  Hi, I'm learning CodeDom scripting, I started with http://www.c-sharpcorner.com/uploadfile/mgold/codedomcalculator08082005003253am/codedomcalculator.aspx Now I'd like to allow script modify the project's form (for learning purposes only). I suppose I need to create new field for a class I'm generating which refers "this". However I have no idea how can I set a reference for script-accessible object ... ? Or can I directly publish some class member (like "this" or "button1") to a CodeDom script structure?

• Accessing custom user profile fields in CCK

  - by Nick Lowman

  I'm probably going about this the wrong way but... I’ve added a field to the User Profile called profile_real_name which is required by the user. Is there a way to access the details in CCK? For example in CCK when creating a new field I can access the user’s username with the ‘User reference’ Field type and setting the ‘Widget type’ to ‘Autocomplete text field’. Can I do the same with my real name field? Many thanks

• Using object instead of AppDelegate for Outlets & Actions?

  - by Driss Zouak

  In all the MonoTouch examples I have seen everyone is using outlets and actions on AppDelegate, yet when I've been through some objective-C webcasts I see people using an Object they drag onto XIB in Interface Builder and using that (Seems a lot cleaner). Is there just not a way to reference any Objects like that that we create? Is there a particular way to access it? Any advice would be appreciated, thanks

• Align 2 sets of 2D point clouds

  - by user108088

  From what I gather, there are two major methods to perform alignment on point clouds, Iterative Closest Point (ICP) and Particle Filtering. What are the advantages of each method? And can someone point me some good tutorials. For what I am currently doing, I think ICP would be easier, I can't seem to find any simple reference implementations online for 2d point sets. Has anyone seen (psuedo)code for ICP with details on the transformation step? Thanks in advance.

• How do you programmatically move the caret of a Flex TextArea to the end?

  - by Akinwale

  I'm trying to move the caret in a Flex TextArea to the end after appending some text from my code. I've looked through the reference documentation for TextArea and its underlying TextField but it appears there is no method provided to handle this. One approach I've tried is to set focus to the text area and dispatch a KeyUp KeyboardEvent with the event's key code set to the "End" key, but this doesn't work. Any ideas on how to do this? Thanks.

  - by Ajeet Kumar Yadav

  The problem is in being able to catch the instance of the player to control it i.e. Stop it, Play it etc. The code by default creates multiple instances of the same player and overlaps the songs. I am being unable to reference the player specifically. Do you have an idea as to how we can do so? Thanks, Arun

• C++: Accessing std::map keys and values

  - by Jay

  How do you access an std::vector of the keys or values of an std::map? Thanks. Edit: I would like to access the actual elements, not just copies of their contents. essentially I want a reference, not a copy. This is essentially what I am wanting to do: std::map<std::string, GLuint> textures_map; // fill map glGenTextures( textures_map.size(), &textures_map.access_values_somehow[0] );

• How to get number of delete using NHibernate IStatistics

  - by epitka

  I am trying to get the number of delete statements issued during the session, so I enabled statistics generation and I got a reference to it through SessionFactory.Statistics. But I don't see a way to get the global number of deletes. I can get the statistics for the entity, but I have one many-to-many mapped relationship that does not materialize in an entity, everything is done through a table that is not mapped to an entity. Is there a way to get this number?

• PHP language specification ?

  - by Rolf

  Hi, as I know there is an official document for Java (JLS), I'd like to know if it's also the case of PHP language. I found the "Language Reference" section on the PHP manual, but it doesn't look as detailed as the JLS. The thing is I have a good practical knowledge of PHP but I'm miserably clueless about what REALLY happens under the hood. If there isn't any official document, could you recommend me some good books to read ? Thanks in advance ! Rolf
