  • get data from online once and then viewable offline

    - by user313100
    Okay, I want to have an app that takes phone numbers from an online database and displays them in a table view. When the user is not online, I want them to still be able to see the numbers they already got from the database in the table view. If the user manages to go back online, the database updates the view. My question is, is this possible to do and if so, what's the best way to approach it? (bit of a newbie, please help me out)

  • How does JSON compare to XML in terms of file size and serialisation/deserialisation time?

    - by nbolton
    I have an application that performs a little slow over the internet due to bandwidth reasons. I have enabled GZip which has improved download time by a significant amout, but I was also considering whether or not I could switch from XML to JSON in order to squeeze out that last bit of performance. Would using JSON make the message size significantly smaller, or just somewhat smaller? Let's say we're talking about 250kB of XML data (which compresses to 30kB).

  • How to draw an CGImage with some alpha transparency?

    - by mystify
    Want to draw an UIImageView which has an CGImage, and the UIImageView has alpha 0.5f. But this CGContextDrawImage function doesnt take an transparency value. So how could I draw an image slightly transparent? To be clear: The image itself is not transparent, but I want it to be "dimmed" a little bit. Just like you would do with an UIImageView and some alpha like 0.5f :-)

  • C# delegate to Java conversion

    - by Derek
    I am in the process of converting some code from C# to Java. I have never used C# before, but it has been pretty easy up to this point. I have a line that looks like this in the C# file: coverage.createMethod = delegate (Gridpoint gp){ //Some method stuff in here, with a return objecct } What exactly is this trying to do? It seems a little bit like an inline class but I am not sure how to go about converting htis to java

  • how to scan a LAN for live hosts using PHP and SNMP?

    - by aag
    I would like to have a quick script listing all active hosts in a LAN, and I am a bit lost. From other posts I figured that this can be done most effectively by polling the DHCP server (in my case a Lancom router) using SNMP. However, I am not familiar with the SNMP commands in PHP. Is snmpwalk() the correct function? Can I get snmpwalk() or any other php function to return an array that contains a list of all live hosts?

  • PHP & JavaScript source code formatters (prettifiers) - NATIVE only apps!

    - by vic
    Hi, I know at least two PHP source prettifiers and one for JavaScript, but all of them are written in those languages - PHP prettifiers in PHP, JavaScript in JS ;] Now what I'm looking for is a prettifier for those languages which is a native application - can be C/C++ or Pascal, so that I can run it from commandline. Possibly open source solution, as I might need to modify it a bit for my needs ... ( i need to run those prettifiers in batch mode ) any known programs / libraries for that?

  • What's the easy way to test for 304 reponses?

    - by John Mee
    I need to test if my 304 responses are working, but my development environment is pretty hard set on force no-cache. Is there an easy way to modify the max-age value of the cache-control header before it goes out? I'm perhaps a bit optimistic in hoping chrome (or an extension, or FF) has a console command letting me alter the if-modified-since header then send the request. Maybe paste something into a telnet connection?

  • Post bacc CS certificate of Java Certification?

    - by gwozdz
    I have a BS in biology, MS in Environmental Science, but I've been writing software in C++ and Java throughout grad school and a bit in my current job. I'd love to transition to a programming career. I've thought about getting what's called a "Post baccalaureate Certificate" or Java certification in lieu of another degree in CS. Which is more useful in terms of getting a job?

  • Naming Convention for Blackberry Development

    - by Nirmal
    I have gone through with some of the sample examples of blackberry. And in some classes I have found some variables are starting from _ like _address and some of them are ALLCAPS. So, i guess it's bit different then the basic Java naming conventions. So, can anybody let me know that is there any difference between Java and blackberry naming convention ? Thanks in advance.

  • Odd behaviour with scala method syntax

    - by Ceilingfish
    Hi chaps, I hit a bit of a quirk of scala's syntax I don't really understand object Board { def getObjectAt(x:Int, y:Int):Placeable = return locations(x)(y) } works fine. But object Board { def getObjectAt(x:Int, y:Int):Placeable { return locations(x)(y) } } returns the error Board.scala:8: error: illegal start of declaration return locations(x)(y) I found some stuff that says the second form convinces the scala compiler you're trying to specify an expansion to the return type Placeable. Is there a way I can fix this, or should I just avoid specifying a return type here?

  • C#, Java, or SharePoint to learn

    - by bmw0128
    I know a bit of each of these, but none enough to pass technical phone screens/interviews. I am looking for a job, and I'll take anything, almost anywhere (in the US). Any opinions on which I should take on and do a deep dive? I do not which technology, I am wondering if one is better than the other when trying to get a job, more in the entry/mid level skill level. I am currently in the Bay Area, but will go anywhere.

  • Javascript plugins design pattern like jQuery

    - by Marco Demaio
    Could someone write down a very simple basic example in javascript to conceptualize (and hopefully make me understand) how the jQuery plugin design pattern is done and how it works? I'm not interested in how creating plugin for jQuery (so no jQuery code here at all). I'm interested in a simple explanation (maybe with a bit of Javascript code) to explain how it is done the plugin concept. Plz do not reply me to go and read jQuery code, I tried, but I it's too complex, otherwise I would have not post a question here.

  • Why is the compiler not complaining about an additional ',' in Array or Object Initializers?

    - by Danvil
    Using simple type like class A { public int X, Y; } with object intializers, one can write var a = new A { X=0, Y=0 }; But the following is also accepted by the compiler: var a = new A { X=0, Y=0, }; // notice the additional ',' Same for int[] v = new int[] { 1, 2, }; This looks a bit strange ... Did they forgot to reject the additional ',' in the compiler or is there a deeper meaning behind this?

  • Code generator tool to generate a property and backing field

    - by MattSlay
    I'm working in VS2008 and C#, and I'm looking for a (free) code generator tool to generate a property with getter and setter, as well as the backing private field to go with. The template thingy in VS does not make the field to go with it. Just looking for something a little bit better. I once saw a web site where you could build this code, then cust-and-paste it from the web page to your code.
