  • Problem with CFNetRegister

    - by xtrahotsauce
    I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

  • Handling orientation changes yourself

    - by synic
    From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest: Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change. Why does it say this? In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity. While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself. Why should it be avoided?

  • 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)

  • Do Java or C++ lack any OO features?

    - by tsv
    I am interested in understanding object-oriented programming in a more academic and abstract way than I currently do, and want to know if there are any object-oriented concepts Java and C++ fail to implement. I realise neither of the languages are "pure" OO, but I am interested in what (if anything) they lack, not what they have extra.

  • Netbeans platform tutorials

    - by James P.
    I mostly use Eclipse but have mentionned Netbeans on my cv. Are there any good concise and up-to-date tutorials apart from the official ones that could bring me up to speed on how to use the platform efficiently (shortcuts, debugging, views ...)? This excludes programming tutorials as I don't really need them unless there's a special manipulation involved.

  • See socket options on existing sockets created by other apps?

    - by nailer
    I'd like to test whether particular socket options have been set on an existing socket. Ie, pretty much everything you can see in: #!/usr/bin/env python '''See possible TCP socket options''' import socket sockettypelist = [x for x in dir(socket) if x.startswith('SO_')] sockettypelist.sort() for sockettype in sockettypelist: print sockettype Anyone know how I can see the options on existing sockets, ie those created by other processes? Alas nearly all the documentation I read on Python socket programming is about making new sockets.

  • Sending / Forwarding variable arguments in ObjectiveC

    - by Authman Apatira
    I know this is possible in other programming languages. Suppose we have the following arrangement: - (void) myMethod:(NSString*)variables, ... { // Handle business here. } - (void) anotherMethod:(NSString*)variables, ... { // We want to pass these variable arguments for handling [self myMethod:variables, ...]; // Do not pass GO } // Start the party: [self anotherMethod:@"arg1", @"arg2", @"arg3", @"arg4", nil]; What's the trick to get this working in ObjC?

  • Get all Vector2 Points Within Radius

    - by CheapDevotion
    I am looking for a formula that will give me all of the Vector2 Points within a certain radius given the center. Essentially what I am trying to do is change the color of each pixel in a 256 x 256 texture that is within a certain radius from a specific pixel (Using the Unity3d Game Engine). Programming Language doesn't really matter, as I can probably convert it to something I can use.
