  • When is the onPreExecute called on an AsyncTask running parallely or concurrently?

    - by Debarshi Dutta
    I am using Android HoneyComb.I need to execute some tasks parallely and I am using AsyncTask's public final AsyncTask executeOnExecutor (Executor exec, Params... params) method.In each separate thread I am computing some values and I need to store then in an ArrayList.I must then sort all the values in the arrayList and then display it in the UI.Now my question is if one of the thread gets completed earlier than the other then will it immediately call the onPostExecute method or onPostExecute method will be called after all the background threads have been completed?MY program implementation depends on what occurs here.

  • basic client/server programming

    - by Zachary
    I am new to web programming...I have been asked to create a simple Internet search application which would allow transmit to the browser some data stored remotely in the server. Considering the client/server architecture (which I am new to) I would like to know if the "client" is represented only by the Internet browser and therefore the entire code of the web application should be stored in the server. As it's a very generic question a generic answer is also well accepted.

  • Why is there no Constant keyword in Java?

    - by harigm
    I am curious learner of Java, and I was thinking about the topic of "CONSTANTS". I have learnt that Java allows us to declare constants by using final keyword. My question is why didn't Java introduce Constant (const) keyword. Since many people say it has come from C++, in C++ we have const keyword. Please share your thoughts.

  • What are the limitations of a STA thread in compare to MTA threads ?

    - by Xaqron
    If we make a thread STA like this: Thread.SetApartmentState(STA); then it cannot run code marked with [MTAThread] attribute. We have seen [STAThread] in windows and console applications but I have never seen code with [MTAThread] attribute and don't know which .NET libraries use this attribute. My question is what are the limitations of a thread with apartment state set to STA, in compare to threads with MTA apartment state (natural .NET threads) ?

  • In MySQL how can I tell what character set a particular table is using?

    - by muudscope
    I have a large mysql table that I think might be using the wrong character set. If so I'll need to change it using ALTER TABLE mytable CONVERT TO CHARACTER SET utf8 But since this is a very large table, I'd rather not run this command unless I have to. So my question is, how can I ask mysql what the character set is on a particular table? I can call status in mysql to see the database's character set, but that doesn't necessarily mean all the tables have the same character set, right?

  • Optimal pixel format for drawing on iPhone?

    - by Felixyz
    Pretty simple question: when doing some pretty intense drawing with CoreGraphics on the iPhone, how can I specify the pixel format to get optimal performance? Is the format that I get from the context via UIGraphicsGetCurrentContext per definition the best one? I know that RGB565 is supposed to be the fastest to use in OpenGL. Does that go for CoreGraphics as well? General advice?

  • How do you pronounce "Enum"?

    - by Davy8
    In the spirit of this question how do you pronounce Enum? Tagging as subjective and community wiki obviously. I've heard E-Nuhm and E-Nnoom any others? Edit: Looks like we have a winner. Thought it'd be a closer race since most of the people at my work use the 2nd one.

  • What does "stupid" in "Keep It Simple, Stupid" mean?

    - by Borek
    I'm not a native speaker and always thought that the last "S" in KISS is a "salutation", like calling me that way if I don't keep things simple. But Wikipedia states that KISS stands for "Keep It Simple and Stupid". Which is "correct" or at least makes sense to you? And yes, this is a stupid question :)

  • Where in an Eclipse workspace is the list of projects stored?

    - by Kris Pruden
    I use eclipse with "external" projects - i.e. projects created from existing source. Poking around in the workspace files, I cannot find any reference to these projects. My question is: how does eclipse keep track of these projects? I'd like to be able to add such a project to the workspace automatically (by generating .project and .classpath files)..

  • FLEX components: updating import statements to move the component into another folder

    - by Patrick
    hi, I've just imported a Flex component into my project. I have a theory question about importing. all the imports statements in the component source files started with "com.subFolder.etc", but I have preferred to move the component folders into "componentName" and to replace all import statements as "componentName.com.subFolder.etc" Is this ok ? Everything works perfectly, but I was wondering if the method is correct. thanks

    - by VaioIsBorn
    I didn't know any better name for a title of the question.

  • Python vs. Java performance (runtime speed)

    - by Bijan
    Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise? You'd think this would be a rather simple question to answer, but I haven't found a decent one. I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?

  • Using an ampersand in scanf()

    - by Rob
    When I compile scanf("%s", &var);, gcc sends back a warning: warning: format ‘%s’ expects type ‘char *’, but argument 2 has type ‘char (*)[20]’ however when I compile scanf("%s", var);, no warning is applied. Both pieces of code work and the book I am reading specifically says to use the ampersand, but even it doesn't in some of the examples. My question is, should I continue to use the ampersand, even when the book doesn't specify?
