  • Algorithm performance

    - by william007
    I am testing an algorithm for different parameters on a computer. I notice the performance fluctuates for each parameters. Say I run for the first time I got 20 ms, second times I got 5ms, third times I got 4ms: But the algorithm should work the same for these 3 times. I am using stopwatch from C# library to count the time, is there a better way to measure the performance without subjecting to those fluctuations?

  • How can I make a numerical value for a taskbar icon in C#?

    - by Waffles
    I'm trying to find a way to display the current processor time of an application to the user via the taskbar when my application is minimized. For reference, I want something like what is implemented in Coretemp, where if you minimize the application, you can still see the temperature of the computer processor cores in the taskbar. Does anyone know of how this is done in C#?

  • YouTube .Net API - Not getting correct View Counts

    - by Ardman
    I've managed to plug away through the YouTube documentation, and have managed to successfully implement the majority of what I want to work. My question is, I get the video View count and it comes back lower than the actual video on YouTube. It was fine this morning and both showed correctly, but now my version is out by 4 views. Does anyone have any experience with this? Or can tell me if they update the values every 5/10/15/24 hours?

  • Controling page number shwon in printing dialog

    - by Matthias Wandel
    I'm trying to implement printing a range of pages in c# While printing, the .net framework throws up a message box that says "Page # of document". This starts at 1, and counts up to the number of pages printed. If I'm printing pages 10-11, I want that count to start at 10, not 1. Is there a way to set the starting value? The logical thing would be if it started at PrinterSettings.FromPage, but it ignores that value.

  • Why can't i define recursive variable in code block?

    - by senia
    Why can't i define a variable recursively in a code block? scala> { | val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _} | } <console>:9: error: forward reference extends over definition of value fibs val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _} ^ scala> val fibs: Stream[Int] = 1 #:: fibs.scanLeft(1){_ + _} fibs: Stream[Int] = Stream(1, ?) lazy keyword solves this problem, but i can't understand why it works without a code block but throws a compilation error in a code block.

  • javascript, jQuery: how to save values instead of the references

    - by Patrick
    hi, I'm using the following lines to store the location of an object. var lightboxTop = $('#lightbox').css('top'); var lightboxLeft = $('#lightbox').css(' left'); I'm successively moving this object in my element, and I want to restore it previous position with the stored variables. But, I'm afraid javascript is saving the values by reference so I lose the initial positions. Am I correct ? How can I solve this ? thanks

  • How to show number of jgrowl notfications?

    - by chobo2
    Hi I am using a pool of 5 with jquery. So only 5 notifications should be shown. I think it would be nice to have maybe under the "close all" button to have a count like shown 5 of 20 notifications. To me it could get confusing if I keep closing notifications and new ones keep poping up. I might think there is some sort of problem with the site. Anyone know how to do this?
