• Generating Bezier Control Points for an object

  - by E.F

  Hello everyone, I'm trying to draw objects using Bezier surfaces with openGL's evaluators. I am struggling with defining the control points for my objects. Can anyone please suggest ways to get the control points for an object? Is there some program that I can use to design my object then import the control points into a file that I can use in my application?

• Boost any usage

  - by Ockonal

  Hello, how can I insert my own class objects into ptr_map from boost. The objects are templated so I can't use some static typename in the map. So I did: ptr_map<string, any> someMap; My class inherits the boost::noncopyable. someMap.insert("Test", new MyClass()); The error is: error: no matching function for call to ‘boost::ptr_map.

• Trouble adding event listeners via JavaScript

  - by Jack Roscoe

  Currently I have a function which loops to create multiple HTML objects. Each time an object is created, I want to add an onClick function listener to that object so that I can trigger a function when each one is clicked. What's the best way to do this? Here's the code which creates my objects: RenderMultipleChoice:function() { this.c = paper.rect(this.x, this.y, this.shapeWidth, this.shapeHeight); }

• I need a 3ds loader for opengl

  - by Shaza

  Hey, I have an opengl project with C++, and I need to load like 10 3ds objects in my scene with their texture on, but unfortunatly the loader I'm using now is causing memory leakage, I knew that when my scene freezed after running the project by one min, so can you suggest a 3ds loader which can be very effective in loading a big number of 3ds objects??

• Two method for linking a object using GCC ?

  - by bluewater

  I've known that I should use -l option for liking objects using GCC. that is gcc -o test test.c -L./ -lmy But I found that "gcc -o test2 test.c libmy.so" is working, too. When I use readelf for those two executable I can't find any difference. Then why people use -l option for linking objects? Does it have any advantage?

• Using build with a has_one association in rails.

  - by espinet

  This is a really noob question but im having trouble finding the answer, is there a way in rails to have 0 or 1 association? For example, I create a user with no objects, than later on create an object for that user. I tried using build with a 'has_one' association but that blew up... The only way I see this working is using 'has_many'. The user is suppose to only have at most one of these objects, is there any way to do this?

• how to load c# object side by side

  - by mamu

  We have serialized value of some objects persisted. Now we want to make substantial changes to some objects. So what i want to do is load older version of object using old assembly then deserialize and serialize again with newer version of the object. I can have convert method which can transform old object to new one. i have been converting object on fly on deserializer but in this case it's almost new object with same name.

• In a project that uses a DI framework, should you NEVER use the 'new' operator?

  - by Chuck

  I'm trying to wrap my head around Dependency Injection. One of the things I'm confused about is whether all of your object instantiation needs to be controlled by the DI framework (Spring, Guice, etc). Or, if not, how do you determine which objects are instantiated by the framework and which objects are instantiated with the new operator?

• Can a python view template be made to be 'safe/secure' if I make it user editable?

  - by Blankman

  Say I need to have a templating system where a user can edit it online using an online editor. So they can put if tags, looping tags etc., but ONLY for specific objects that I want to inject into the template. Can this be made to be safe from security issues? i.e. them somehow outputing sql connection string information or scripting things outside of the allowable tags and injected objects.

Please help me if you can.

• Complex movement within animation

  - by Irwin

  I've this application, where two children are playing catch. One throws and the other catches. While I can show a ball object moving between two stationary objects, how do I show the objects "releasing" and "catching" the ball, in a way that is close to lifelike? EDIT: The movement of the hands in this game: http://www.acreativedesktop.com/animation-game-slaphands.html is what I would like to replicate. Any tips on how to do that?

• Weblogic 10.3 domain unpacking problem

  - by MarkoU

  Hi, I'm trying to unpack a Weblogic 10.3 domain on one of our production servers (SunOS 5.10), but get the following error: $ /opt/bea10/wlserver_10.3/common/bin/unpack.sh -template=/tmp/CM.jar -domain=/opt/bea10/user_projects/CM Error: failed to create the temporary script file Assuming that this is a priviledge problem: where actually the unpack utility tries to create its temporary script files? The unpack script calls a Java class com.bea.plateng.domain.script.Unpacker, so reading the script itself does not reveal the location. I need to ask the sysadmin for the priviledges, so an exact directory location is needed. Of course, the error message is so vague that this might also be some other issue. Any ideas? BR, Marko P.S. Sorry for cross-posting. I tried this question also on Serverfault but got no replies. Perhaps programmers (like myself) do this kind of stuff anyway.

• Core Data strategy using in memory cache, or no core data at all?

  - by randombits

  I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?

• IronPython memory leak?

  - by Mike Gates

  Run this: for i in range(1000000000): a = [] It looks like the list objects being created never get marked for garbage collection. From a memory profiler, it looks like the interpreter's stack frame is holding onto all the list objects, so GC can never do anything about it. Is this by design?

• How to install Qt on Windows after building?

  - by Piotr Dobrogost

  I can't find any information on how to install Qt built on Windows. In wiki article How to set up shadow builds on Mac and Linux there's description of -prefix option in configure script but this option is not available on Windows. I know I can use Qt right from the build folder but it does not seem the right thing not to perform an install step. One problem with this approach is size; Qt's build folder takes about 4GB space whereas after installing using binary installer Qt takes about 1GB space. I guess the difference is due to temporary files created during building. I hope some install procedure would install (copy) only needed files leaving temporary files in the build folder.

• Is there a better way to format this Python/Django code as valid PEP8?

  I have code written both ways and I see flaws in both of them. Is there another way to write this or is one approach more "correct" than the other? def functionOne(subscriber): try: results = MyModelObject.objects.filter( project__id=1, status=MyModelObject.STATUS.accepted, subscriber=subscriber).values_list( 'project_id', flat=True).order_by('-created_on') except: pass def functionOne(subscriber): try: results = MyModelObject.objects.filter( project__id=1, status=MyModelObject.STATUS.accepted, subscriber=subscriber) results = results.values_list('project_id', flat=True) results = results.order_by('-created_on') except: pass

• How to achieve an eagerly loaded, filtered child collection with the NHibernate criteria API

  - by vakman

  Is it possible to use the criteria api to load a set of parent objects along with a filtered, eagerly loaded set of child objects? I'm trying to query a list of categories and at the same time load the categories products that start with the letter M. The query below gives me the results I want but the Products are not eagerly loaded, that is NHibernate performs additional queries when I enumerate the Product collection: var categoriesWithProducts = session.CreateCriteria<Category>() .SetFetchMode("Products", FetchMode.Eager) .CreateCriteria("Products") .Add(Expression.Like("Name", "M%")) .List<Category>(); What am I missing here?

• Accessing Sharepoint tasks via web services?

  - by scooterhanson

  I've looked at a lot of the previous questions asked about sharepoint and accessing objects via web-services, and I am pretty convinced that tasks can be accessed through the Lists interface. Can anybody please verify this for me? Also, if anyone has any examples of this I would be very grateful. I'm not a Sharepoint guy but I need to connect to an instance just to retrieve task objects.
