  • Array increment operator

    - by Stardust
    Could any one please tell me the meaning of "++" with array in the following code in Java: int [ ] arr = new int[ 4 ]; for(int i = 0; i < arr.length; i++){ arr[ i ] = i + 1; System.out.println(arr[ i ]++); } what is arr[ i ]++ meaning in above code, and why we can't do like: arr[ i ]++ = i + 1;

    - by Soo
    I want to create a background worker for a WinForm that triggers code whenever midnight rolls by. I have an idea of how to do it, but I'm pretty sure it's not the best way to do it. while(1==1) { //if Datetime.Now == midnight, execute code //sleep(1second) }

  • bounce multiple servers using ant

    - by Angrezy
    Hi All, This is restart target code which is defined in build.xml target name="restart" propertycopy name="remote.host" from="deploy.${target.env}.host.${remote.id}" propertycopy name="remote.port" from="deploy.${target.env}.port.${remote.id}" sshexec trust="true" host="${remote.host}" port="${remote.port}" username="${scm.user}" keyfile="${scm.user.key}" command="sudo /usr/local/bin/bounce_jboss" target server information is defined in build.properties. The above code is working fine, but the restarting process is very late bcas its stopping-starting server one and later its stopping-starting another server, Is there a way where i can restart both servers parallely with a time frame of 45 seconds.

  • point of UIViewController in IB

    - by Jonathan
    What exactly is the point of adding a UIViewController in IB? There is no way to add code like you can if you create a viewController in Xcode? And if you can what is the advantage of doing it in IB. And isn't the whole point of a MVC to seperate code into "modular" parts so why would add a ViewController in IB

  • Subversion branch question

    - by aspdotnetuser
    Hi, If you have created a branch and are working with the files in that branch, when you 'update' it, is it updating/merging the code in the branch with the code in the trunk? Also, when you have commited your changes to the branch, how do you update the trunk with your changes? (since you commit the changes and have to switch to the trunk again?) Any comments will be appreciated :) Thanks,

  • pdf <pre> equivalent

    - by ddowns
    I'm trying to put some code examples in a pdf, but copying them out messes up the formatting and rearranges the lines, there's a lot of manual cleanup needed after pasting. Is there a equivalent to html's pre for PDFs? For "this" block of text respect line breaks, spacing, and copy as plain text like its shown. The closest thing I can see is adding note annotations next to every code example.

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?

  • Where do you put your unit test?

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewers?

  • .NET - alpha-numeric representation of numbers

    - by mack369
    I'm implementing serial key functionality in my application. User needs to enter at least 64bit number in order to register the application. Because typing number like 9,223,372,036,854,775,807 will take a while I want to compress it a bit. The first guess was to code this number hexadecimally but it still is quite long (0x7FFF FFFF FFFF FFFF). Is there any standard method in .NET to code this number alphanumerically using for example: digits, upper-case and lower-case characters?

  • What is unit testing?

    - by Alon
    What is unit testing and unit testing libraries like xUnit? I understood it's testing specific code, so what's the difference between this and just opening a new project and test this specific code?

  • Redirect in Application_Error redundant if using customErrors?

    - by Ek0nomik
    If I have a customErrors section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don't want to go to a separate page I don't think I need the code.

  • nested updatepanels

    - by Elenor
    When I put nested updatepanels in outer updatepanel, then in code, it shows that outer panel is around the code of all nested panels while design mode shows outer updatepanel is drawn like one row on top of page and nested updatepanels are drawn below that outside of outer updatepanel. Is this normal behavior or there is some problem in my implementation?

  • it takes 2 seconds to compile a hello world C++ project in netbeans (windows)

    - by Ethan
    I used code:blocks as the C++ IDE on Windows. I switched to netbeans 6.8 (with C/C++ plugin, MinGW, MSYS) recently, because netbeas have the nice feature of "checking syntax errors when typing" (same as working on Java or PHP projects). But the painful thing is that, it takes 2 seconds to compile a simple hello world project in netbeans. Any trick to make it as fast as code:blocks, or at least make the compiling time no more than 0.5 second?

  • Finding databases for use in applications

    - by JonF
    Does anyone have some recommendations on how I can find databases for random things that I might want to use in my application. For example, a database of zip code locations, area code cities, car engines, IP address locations, or whatever. I'm just asking generally when you decide you need a bunch of data where are some good places to start looking other than google?

  • Working with the IE cache from C# & WPF

    - by Eric
    I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

  • How can I execute a non-blocking System.Beep() in C#?

    - by Siracuse
    In C# I can perform a Console.Beep(). However, if you specify a duration of say 1000, or 1 second, it will not execute the next line of code until that second passes. Is there any way possible to execute Console.Beep() in a non-blocking fashion so it will continue to beep and still continue executing the code below it while beeping?
