• Change TreeNode image on expand-collapse events

  - by Alexander Stalt

  I have a treeView with many nodes. I want that some nodes change their image when node collapsed/expanded. How can I do it ? Unfortunately, TreeNode don't have properties like ExpandNodeImage, CollapseNodeImage \ TreeView can change very often, so nodes can be deleted/added.. i can delete child nodes and so on... Maybe, there is a class like ExpandAndCollapseNode ?

• what's the way to determine if an Int a perfect square in Haskell?

  - by valya

  I need a simple function is_square :: Int -> Bool which determines if an Int N a perfect square (is there an integer x such that x*x = N). Of course I can just write something like is_square n = sq * sq == n where sq = floor $ sqrt $ (fromIntegral n::Double) but it looks terrible! Maybe there is a common simple way to implement such predicate?

• Django and Drupal

  - by webzide

  Dear Experts, Since Django is a web development framework and Django is a CMS. Is it possible to use them both together instead of a preferred database on Django like apache?

• CodeCharge : is it any good?

  - by David Burrows

  Hi, A job came in to me that's built with CodeCharge - had a look at it and seems to be a pretty basic point-and-click site builder tool. Has anyone got any in-depth experience with it? My first reaction is one of horror and to just rebuild the code in Rails or PHP but I thought I'd ask the question first, maybe i'm missing something...

• How to make a Generic Repository?

  - by chobo2

  Hi I am wondering if anyone has any good tutorials(or maybe even a library that is already made and well documented) on making a generic repository. I am using currently linq to sql but it might change so I don't know if you can make a generic repository that would take little to no changes if I would say switch to entity framework. Thanks

• Are there any open source video transcoding servers?

  - by maxfridbe

  Are there any servers written that can be setup to take video transcode jobs? I am looking to set one up to work just like the service Zencoder.

• What features would you like to see added to C++?

  - by George Edison

  Are there any features you would like to see added to C++? Maybe... A programming construct An extra operator A built-in function you think would be useful I realize questions like this are frowned upon, but I think this one is a genuine programming question that can be answered and the answers will spawn valuable discussion. (And it's community wiki.) Here is one of mine: How come C++ has no exponent operator, like Python's **?

• Best beginner programming language?

  - by mtwisterr

  I want to learn a simple language so I can code simple things maybe eventually a game but I don't know where to start. I can code simple things using apple script but you can't do that much with that and it only works on macs. I have a mac and a dell so something that I could code and run on both would be nice. Also all my school offers is java so if you have any ideas on how to learn the language that would be appreciated. Thanks

• Online validators, syntax checkers, testing tools

  - by Max Gontar

  I often need to verify some simple code before posting, and it's great if I have installed IDE, but what if not? It would be nice to have online free tools for SQL, VB.NET, C# code validation, or maybe even testing. EDIT What I actually mean are online live web tools, like JSLint for javascript. Have you seen any?

• Do you keep a code bank?

  - by calico-cat

  I've done consulting work for years and I've got code snippets in various languages lying around that I'll re-use for various projects. The collection is getting pretty large and I want to set up a code bank for myself. What code banks do people use? Do you find it helps, or is there some better way of organising my reusable code snippets? (If one does exist, I'd prefer it be open-source, accessible via a web browser, language-agnostic, and maybe colour the code the way Stackoverflow does :)

• work benefits package [closed]

  - by Francisco Garcia

  For those of you who are into programming not just for the money. I would like to know which benefits you would like to have (or already have). OK, maybe taking away the money factor will limit this question too much. I am surprised to see that most companies have a fixed set for their benefits package. Were you able to negotiate something new or just your salary? What things have you seen out there and/or value most?

• Which parts of Graphics Pipelines are done using CPU & GPU?

  - by afriza

  Which parts of pipelines are done using CPU and which are done using GPU? Reading Wikipedia on Graphics Pipeline, maybe my question does not precisely represent what I am asking. Referring to this question, which "steps" are done in CPU and which are done in GPU? Edit: My question is more into which parts of logical high level steps needed to display terrain+3D models are using CPU/GPU instead of which functions.

• Would you like ASP.NET MVC view engine in which a view is created entirely in Code?

  - by amartynov

  Recently I created a spike of a view engine, in which views are plain classes, and the content is created by using funny using-scope blocks. The code together with a simple sample site is available at http://code.google.com/p/sharp-view-engine/ Here I'd like to hear your opinions regarding such an idea. Is it completely weird or maybe someone likes it?
