    - by Michael Lu
    I store file’s attributes (size, update time…) in database. So the problem is how to manage transaction for database and file. In jee environment, JTA is just able to manage database transaction. In case, updating database is successful but file operation fails, should I write file-rollback method for this? Moreover, file operation in EJB container violates EJB spec. What’s your opinion? Thank!

  • Android files manipulation

    - by klaus-vlad
    Hi, Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? To me it is very handy to do it this way but I've read that not always the java functions can be applied when it comes to files in Android.

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

    - by alnet
    I need to write a rate limiter, that will perform some stuff each time X bytes were transmitted. The straightforward is to check the length of each transmitted packet, but I think it will be to slow for me. Is there a way to use some king of network event, that will be triggered by transmitted packets/bytes?

    - by matt
    When I try to write a field that includes whitespace in it, it gets split into multiple fields on the space. What's causing this? It's driving me insane.

  • Generating db schema from c# class

    - by Niran
    Hi, Is there any other method than nHibernate by wich we can generate db schema from class definition? My classes arn't that complex etc (few one-to-many relations). However I would like to just be able to save my objects in db and recreate schema if needed. I am stuck with .NET 2.0. I am not that particular about performance for this project, I am just lazy to create tables and write save/load code and deel with nHibernate xml. Thanks

  • Detecting I/O errors in a NON BLOCKING SOCKET

    - by ripunjay-tripathi-gmail-com
    I am writing a client - server system in which I used NON-BLOCKING sockets. My problem is to detect error { while performing send() or write() } that may occur while data transfer. Example lets say, while the data is being transferred the peer crashes. Another case there is some network problem, something like wire unplugged etc. As of now, I am using a high level ACK, that peer sends after receiving the complete data. Ripunjay Tripathi

    - by niklassaers
    Hi guys, I have an object NetworkMember that has no attributes but is defined by its relationships Person, Network, Level and Role. In my app, I've found all the four relationships, but I want to make sure not to double-register my NetworkMember, thus I'd like to search for this NSManagedObject before instantiating it. How should I write a query that queries for an NSManagedObject just consisting of relationships? Cheers Nik

  • Drawing on top of every windows on X11

    - by Vítor Baptista
    Hi, I am trying to make an arcade machine. The user will purchase credits, which will allow him to play for X minutes. I want to write "9:42 minutes left" at the left corner of the screen, even if he's playing a full screen game (UrbanTerror, for example). I would really like if I could do this with Ruby, but any other language is OK. Any ideas? Thanks in advance.

  • ASP.NET Writing to the Bin directory, access denied when anonymous user

    - by LeeW
    Hi all I have a program that creates a small file in the Bin directory for the purpose of tracking a license (that's the intention), all works fine when debugging but I've just realized that when I run it on a IIS server under the anonymous user account (IUSR) the file isn't created as IUSR only has read permission (I know this is correct but drat!). Can I write to another location under IUSR account or can I run my code under 'Local Service' account? Thanks
