    - by Tom Richards
    I have an app on the market that requires sdk 2.0 I want to rewrite and publish it using 1.6 to find a wider audience. The question is: if I update my already published app with an sdk downgrade to 1.6 will it then show up to users with phones at 1.6? I know currently the market search shows my app only to those that have 2.0 phones.

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • java api design - NULL or Exception

    - by srini.venigalla
    Is it better to return a null value or throw an exception from an API method? Returning a null requires ugly null checks all over, and cause a major quality problem if the return is not checked. Throwing an exception forces the user to code for the faulty condition, but since Java exceptions bubble up and force the caller code to handle them, in general, using custom exceptions may be a bad idea (specifically in java). Any sound and practical advice?

    - by aruwanwan
    I´m just starting iPhone development with a small team of (really young and naive) colleagues, we all are fairly new to OS X, my question is: If we are planning to develop for every iPod Touch/iPhone out there (not the iPad, I read that thing requires Snow Leopard), what problems will we encounter when sharing code (and making commits) if we all have a combination of Leopard and Snow Leopard systems?

  • Make a mouse pointer do a hyper-jump?

    - by John M
    I run a dual monitor setup. To get from monitor 1 to 2 (or vice-versa) requires lots of unnecessary mouse movement. My thought was to leverage a extra mouse button (I have two) and have the mouse hyper-jump (apologies to Star Trek) from the XY coordinates on monitor 1 to the same XY coordinates on monitor 2. How would I go about doing this? Could it be done via C#?

  • how to use store define in store folder

    - by Kevin Morfin
    I'm new to sencha-touch. I was wondering how to properly use the file structure in sencha-touch. For example, under the app folder there's your controller, model, profile, store, view folders. If I define a store, for example under the the store folder I create a file named search.js Ext.define('Volunteer.store.search'{ extend: 'Ext.data.Store', requires: ['Volunteer.model.person'], config:{ model: 'Volunteer.model.person' } }); How do I use this store in a different file?

  • Compiling Enet in iphone xcode project

    - by EToreo
    Hello, I am trying to compile the Enet source code into my code framework for iPhone games. After modifying the header files I get it compiling and linking, but I absolutely must be compiling with the "Compile Source As" set to "Objective-C++" in my xcode project (because the framework code requires this). When I flip this switch in my test project, I get these errors: Undefined symbols: "_enet_list_clear", referenced from: _enet_host_connect in host.o ... Can anyone help get this linking with "Compile Source As" set to "Objective-C++"?

Anyone knows why it's like this and if there is some link somewhere where Visual Studio 2005 Express is available?

  • Understanding EXE Internals

    - by Steve
    I was attempting to install an exe that requires a serial number before the install, which the vendor has not provided to us yet. This got my wheels turning about whether there is any information that can be gained from viewing an exe using a hex editor/VI/etc? Using VI to view an exe, I can see some sections of plain text, but it is difficult to determine what it refers to without any context around it. Is it possible to determine any information by reading an exe? Thanks

  • Easy XML Serializer for Java

    - by sdoca
    I'm looking for a way to serialize Java objects into XML for use by a RESTful web service. I don't have an XSD. I have looked at the following: JAXB - fairly heavy weight with annotations required on classes and also an ObjectFactory class and/or a jaxb.index file Simple - requires annotations but no other config classes/files. Unfortunately it can't serialize Sets. XStream - no annotations etc. required, but doesn't support generics Does anyone else have any suggestions?
