  • Eclipse RCP Application Fails to launch second time

    - by ibuck
    I have an Eclipse RCP application that will launch properly after a clean install (right after build). The issue is that if I try to launch the application a second time the application throws an exception. I have narrowed the issue down to this file being created after the first run: ~install_dir/configuration/org.eclipse.osgi/.state Has anyone run into a similar issue where the .state file prevents the application from being launched anytime after that first run? I'm hesitant to look at the exception as this does not happen the first time, so I suspect org.eclipse.osgi is more to blame. The details of the exception are: "Error creating bean with name 'luceneRawQueryComposer' defined in class path resource [spring/dataaccess/daoCMClient.xml]: Cannot resolve reference to bean 'indexUtility' while setting bean property 'indexUtility'; NoSuchBeanDefinitionException

  • Time required for a process to complete

    - by yelkawar
    I am new to C# world. I am attempting to calculate time taken by a algorithum for the purpose of comparison. Following code measures the elapsed time from when a subroutine is called until the subroutine returns to the main program.This example is taken from "Data structures through C#" by Michael McMillan. After running this program the output is Time=0, which is incorrect. The program appears to be logically correct. Can anybody help me. Following is the code using System.Collections.Generic; using System.Collections; using System.Linq; using System.Text; namespace Chap1 { class Program { static void Main(string[] args) { int num1 = 100; int num2 = 200; Console.WriteLine("num1: " + num1); Console.WriteLine("num2: " + num2); Swap<int>(ref num1, ref num2); Console.WriteLine("num1: " + num1); Console.WriteLine("num2: " + num2); string str1 = "Sam"; string str2 = "Tom"; Console.WriteLine("String 1: " + str1); Console.WriteLine("String 2: " + str2); Swap<string>(ref str1, ref str2); Console.WriteLine("String 1: " + str1); Console.WriteLine("String 2: " + str2); Console.ReadKey(); } static void Swap<T>(ref T val1, ref T val2) { T temp; temp = val1; val1 = val2; val2 = temp; } } class Timing { TimeSpan StartTiming; TimeSpan duration; public Timing() { StartTiming = new TimeSpan(0); duration = new TimeSpan(0); } public TimeSpan startTime() { GC.Collect(); GC.WaitForPendingFinalizers(); StartTiming = Process.GetCurrentProcess().Threads[0].UserProcessorTime; return StartTiming; } public void stopTime() { duration = Process.GetCurrentProcess().Threads[0].UserProcessorTime.Subtract(StartTiming); } public TimeSpan result() { return duration; } } }

  • Listing time every second as a Bash script

    - by Caleb
    Hello all, first time here as I've finally started to learn programming. Anyway, I'm just trying to print the time in nanoseconds every second here, and I have this: #!/usr/bin/env bash while true; do date=(date +%N) ; echo $date ; sleep 1 ; done Now, that simply yields a string of date's, which isn't what I want. My learning has been rather messy, so I hope you'll excuse me for this if it's really simple. Also, I did manage to fine this, that worked on the prompt: while true ; do date +%N ; sleep 1 ; done But that obviously doesn't work as a script.

  • C# simpler run time generics

    - by Hellfrost
    Is there a way to invoke a generic function with a type known only at run time? I'm trying to do something like: static void bar() { object b = 6; string c = foo<typeof(b)>(); } static string foo<T>() { return typeof (T).Name; } Basically I want to decide on the type parameter only at run time, but the function I'm calling depends on the type parameter. Also I know this can be done with reflections... but it's not the nicest solution to the problem... I'm sort of looking for dynamic features in C#...

  • UIWebView loads a local file for a long time

    - by Knodel
    I have a UIWebView which loads .rtfd.zip files like this: -(void)viewWillAppear:(BOOL)animated { self.title=@"Title"; if(rowPosledovatelnosti==0) { [self loadFile:@"PosledovatelnostiObzie.rtfd.zip"]; } if(rowPosledovatelnosti==1) { [self loadFile:@"Arifmeticheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==2) { [self loadFile:@"Svojstva_Arifmeticheskoj.rtfd.zip"]; } if(rowPosledovatelnosti==3) { [self loadFile:@"Geometricheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==4) { [self loadFile:@"Predel_Posledovatelnosti.rtfd.zip"]; } if(rowPosledovatelnosti==5) { [self loadFile:@"Summa_Geometricheskoy.rtfd.zip"]; } } But on the device it takes some time for the UIWebView to load the content. Is there any way to optimize the loading time?

  • Basic date/time manipulation in NHiberate query

    - by Yann Trevin
    I'm trying to restrict my NHibernate query with some basic date/time manipulation. More specifically, I want to execute the following statement (pseudo-SQL): select * from article where created_on + lifespan >= sysdate with: created_on is mapped to a property of type DateTime. lifespan is mapped to a property of type TimeSpan. sysdate is the current date/time (of the database server or ofthe application host, I don't care) Is there any built-in way to do that by using the Criteria-API or HQL? return session .CreateCriteria<Article>() .Add( ? ) .List<Article>();

  • Writing datatable to database file, one record at a time

    - by Kevin
    I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time.

  • algorithm advice for finding maximum items within a time period

    - by darren
    Hi everyone. I have a database schema that is similar to the following: | User | Event | Date |--------|---------------|------ | 111 | Walked dog | 2009-10-1 | 222 | Walked dog | 2009-10-2 | 333 | Fed Fish | 2009-10-5 | 222 | Did Laundry | 2009-10-6 | 111 | Fed Fish | 2009-10-7 | 111 | Walked dog | 2009-10-18 | 222 | Walked dog | 2009-10-19 | 111 | Fed Fish | 2009-10-21 I would like to produce a query that returns the maximum number of times a user performs some action within a time period. For example, given a time period of 5 days, what is the maximum number of times user 111 walked the dog? The most obvious solution would be to start at some zero point and move forward each day, summing up 5 day periods along the way, then taking the maximum total out of all the 5 day windows. the approach seems incredibly costly however. I would appreciate any suggestions you may have.

  • How to use error provider at run time along with associating any control to validate

    - by Shantanu Gupta
    I am trying to create a Validation in a reusable fashion. Purpose: Make the validation control reusable. Error Provider should associate with control passed dynamically and can be set or cleared at run time. When user press OnClick event then all the controls gets validated with their own Error Providers. public bool IsFieldEmpty(ref TextBox txtControl, Boolean SetErrorProvider,string msgToShowOnError) { ErrorProvider EP = new ErrorProvider(); if (txtControl.Text == string.Empty) { if(SetErrorProvider==true) EP.SetError(txtControl, msgToShowOnError); return true; } else { if(SetErrorProvider==true) EP.Clear(); return false; } } Issue: Every time the function is called new errorprovider object gets created which i dont want. Every control should not have more than 1 error provider and i should be able to search it just like as done in asp.net to search for some control on a Page. How can I do this

  • Keep an ASP.NET IIS website responsive when time between visits is long

    - by Abel
    After years of ASP.NET development I'm actually quite surprised that I can't seem to find a satisfying solution for this. Why does an IIS ASP.NET site always seem to fall asleep (for 2-6 seconds) after a certain time of inactivity (after several hours), during which no HTTP response is sent from server to client. This happens on any type of site, one page or many, db or not, regardless the settings. How can I fix this? During the wait time, the server is not busy and there are no high peaks or (.NET) memory shortages. My guess is, it has to do with Windows moving the IIS process to the background and its memory to the page file, but I'm not sure. Anybody any idea? EDIT: one solution is to send some HTTP request once an hour or so, but I hope for something more constructive. EDIT: what I meant is: after hours of inactivity, it pauses several seconds on any new HTTP request.

  • ConfigMgr 2012 - How to automatically make updates available to computers without forcing them to be installed?

    - by Massimo
    I'm using System Center Configuration Manager 2012 with the Software Update Point feature; however, in this environment patching has to be strictly manual, because server reboots need to be approved and scheduled by different people; thus, I need to use ConfigMgr's SUP like I would use a plain WSUS server with auto-approval but with manual installation. I created some Automatic Deployment Rules to automatically download and deploy critical updates, and to have an installation dealine of "as soon as possible"; but then, I've also configured those rules to not do anything when the deadline is reached, and to not perform system restarts even if needed (see image). Also, I've configured the device collection to where those rules deploy updates to not have any valid maintencance window. However, I'm experiencing quite the opposite as what I was expecting: as soon as the new updates are processed by the ADRs, they get automatically installed on all systems by the Software Center, and the computers are subsequently restarted. Why is this happening? Am I getting something wrong or is just ConfigMgr 2012 not behaving like it should?

  • Getting a value from a row at particular time

    - by Swetha Bindu
    I had a row in my database: starttime:4/6/2012 2:00pm, Endtime:31/12/9999, name:"swetha", status:"open"..... When I update this row I changed the starttime to the current time (getdate()) and have no issues. I am running a Windows Service each day at 1am to modify a value in the row. I would like to know the status of my row at 4/6/2012 11:59 pm when my service runs. There is no need to do an update at 4/6/2012 11:59 pm and the last update may be at any time of the day however my requirement is to get the status value at 4/6/2012 11:59 pm. I would like to have the query in SQL Server 2008. Can anyone please help me to find a solution?
