• Using ListViews on Android?

  - by Robert

  I am just getting started with the Android SDK and I had a quick question. I am trying to set up a ListView with a rectangle of color on the left and then a bit of text for each row. I also want to make it so I can click each entry in the list and open a new activity to display some information (similar to the contact list). Anyone have any examples to help me out?

• Remember Chromeless Windows?

  - by AGoodDisplayName

  We used to be able to use javascript in IE to produce a chromeless window...no buttons, scrollbars or even the standard edges of the browser window. My question: Is there any way to accomplish this type of window look from the web with today's browsers?

• Overload with different return type in java?

  - by nunos

  So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

• What is the difference between printf() and puts() in C?

  - by alex

  First up, I should let you know that I am learning C, so my apologies if this question seems stupid to a more advanced developer. I know you can print with printf() and puts(). I can also see that printf() allows you to embed variables inside and do some stuff like formatting. Is puts() merely a primitive version of printf(). Should it be used for every possible printf() without string interpolation? Thanks

• Using Joins vs Entity associations

  - by shivesh

• Is it possible to use JSF+Facelets with HTML 4/5?

  - by Bytecode Ninja

  Facelets relies on XML namespaces to work with XHTML. How are HTML 4, and as far as I know, HTML 5 do not support namespaces. Also HTML 5 has some new elements that are not available in XHTML. Even HTML 4 and XHTML have some differences regarding elements and attributes they support. The question is: Is it possible to render HTML 4/5 documents using Facelets? If so, how?

• Windows Application Data Directory

  - by JP

  Not completely a programming question, but its close enough so here goes: In Mac OS I'll put user-specific files for my app in ~/Library/Application Data/{MyApp}/ and in *nix I'll put them in ~/.{MyApp}/ - where should I put them for Windows? I'll be using Ruby's File.expand_path to get to this directory, so if there's a windows equivalent of ~ then that's fine. (Answers for Windows XP, Vista and 7 would be appreciated if they're not the same)

• Query interface for iPhone CoreData store

  - by JT

  Hi, another iPhone newbie question... I have the following: NSPersistentStoreCoordinator NSManagedObjectContext NSManagedObjectModel Is it possible to run queries directly on the store (since its a sqlite DB)? I'm trying to delete all the records from a tableview, and figured a "DELETE FROM table" would be nice and quick as opposed to looping through the records and removing them manually (which i'm also struggling with). Thanks for your time, James

• HashMap.containsValue - What's the point?

  - by Frederik

  I've got a HashMap and I need to fetch an item by its integer value. I notice there's a containsValue() function, but it would appear I still have to iterate through the map to find the correct index anyway. My question is; why use containsValue() if I'm required to traverse it afterwards? Also, am I missing the point completely? ;-)

• Is Perforce's C++ P4API thread-safe?

  - by Scott Bilas

  Simple question - is the C++ API provided by Perforce thread-safe? There is no mention of it in the documentation. By "thread-safe" I mean for server requests from the client. Obviously there will be issues if I have multiple threads trying to set client names and such on the same connection. But given a single connection object, can I have multiple threads fetching changelists, getting status, translating files through a p4 map, etc.?

  Does any programming language use =/= for not-equal? Are there any lexical difficulties for scanners to recognize such an operator? Or was it the case historically? [Note: this is NOT a homework question. I'm just curious.]

• YUI vs jQuery, for css style layouts

  - by tony

  Hi Complete novice question. I've used jQuery a bit, YUI not at all and know very little about it. I work on a website thats IE specific, we're now looking at making it cross browser. jQuery seems great at hiding the differences between browsers from a javascript point of view. However in terms of css layout is it YUI that I should really be looking at? thanks

• When to Multithread and when not to Multithread c++ applications?

  - by Ashwin

  I have been in an assumption that multithreading gives a lot of flexibility and power to make efficient programs. But I am wrong. Multithreading is sometimes not desirable as it will create serious impact on the way the actual program behaves. My question? I am not sure of when to use and when not to use multithreads in applications. Please update this thread and give your opinions on multithreading and suggestions on its usage scenarios.

• Where are the default aliases defined in powershell?

  - by Xerion

  This may be a stupid question, but are the default aliases (e.g. cd) hardcoded in powershell or defined in a hidden "profile" script somewhere? I don't have any profiles set (per-user or system-wide) so I'm just wondering where the default ones come from.

• unprotected access to member in property get

  - by Lenik

  I have a property public ObservableCollection<string> Name { get { return _nameCache; } } _nameCache is updated by multiple threads in other class methods. The updates are guarded by a lock. The question is: should I use the same lock around my return statement? Will not using a lock lead to a race condition?
