  • C# Deleting Locked Files & Folders

    - by orangecl4now
    Hello I am writing an application that updates some drivers. However the drivers are "in use" and can't be deleted unless I restart my computer. So how can I write an application to delete these locked drivers without restarting the PC. IF Restarting MUST occur then how can I relaunch my application automatically when the computer restarts and delete those files?

  • floating point precision in ruby on rails model validations

    - by Chris Allison
    Hello I am trying to validate a dollar amount using a regex: ^[0-9]+\.[0-9]{2}$ This works fine, but whenever a user submits the form and the dollar amount ends in 0(zero), ruby(or rails?) chops the 0 off. So 500.00 turns into 500.0 thus failing the regex validation. Is there any way to make ruby/rails keep the format entered by the user, regardless of trailing zeros?

  • Sources of latency in sending-receiving tcp/udp packets in linux

    - by osgx
    Hello What are sources of latency in process of sending/receiving tcp/udp packets in linux 2.6 ? I want to know a latency sources in "ping-pong" latency tests. There are some rather good papers of ethernet latency, but they cover only latency sources in the wire and switch (and rather cursory, only for specific switch). What steps of processing does follow a packet? Papers with deep latency analysis of usual ping (icmp) will be useful too. I rely on community :)

  • How to apply Single Responsibility Principle to a service class

    - by Shekhar
    Hello Suppose we are designing a UserServiceImpl class which does CRUD(Create, Read, Update, and Delete) operations. In my view Create, Read, Update, and Delete are four reasons for a class to change. Does this class violates Single Responsibility Principle? If it violates, then should we have four classes like CreateUserServiceImpl, ReadUserServiceImpl, UpdateUserServiceImpl, and DeleteUserServiceImpl. Isn't it an overkill to have lots of classes? Thanks Shekhar

  • Zend_Paginator - Increase querys

    - by poru
    Hello, I started using Zend_Paginator, it works everything fine but I noticed that there is one more query which slows the load time down. The additional query: SELECT COUNT(1) AS `zend_paginator_row_count` FROM `content` The normal query: SELECT `content`.`id`, `content`.`name` FROM `content` LIMIT 2 PHP: $adapter = new Zend_Paginator_Adapter_DbSelect($table->select()->from($table, array('id', 'name'))); $paginator = new Zend_Paginator($adapter); Could I merge the two querys into one (for better performance)?

  • using #define in a .pch

    - by ML
    Hello All, If I define something in a pre-compiled header like: #define __BUILD_MAC__ and then in a header file do: #ifdef __BUILD_MAC__ typedef void* HINSTANCE; #endif This should work. But for some reason It isn't. I know because when I compile I get errors about HINSTANCE not naming a type. Do I need to do anything else to make these defines available?

  • Fortran bus error on mac

    - by SteveJ
    The following Fortran code is giving me a bus error on my Mac but no errors when I run it on my Linux machine: PROGRAM TINY WRITE(UNIT=*, FMT=*) 'Hello, world!' END My understanding is that a bus error occurs when the program attempts to access impossible memory but I do not understand where such an attempt has been made in this program. My MacBook has GCC 4.4.0 and my Linux machine has GCC 4.3.2. Any ideas as to why this error occurs?

Thanks in advance, Eli
