  • Linq to SQL and Realtime Data

    - by Jeremy
    I have an application that needs to constantly (every 50ms), call to an MVC action, and pickup/drop off data. I am using Linq to SQL and MVC because of how simple they are to implement, and I know that they aren't perfect when it comes to performance, but it works relatively well, but the best speed I can get with my current approach is 200ms (without requests overlapping). Each call to the site will create a new instance of the datacontext, query/insert it and return that data. Is there a way to have the datacontext static, but submitchanges say every 5 seconds, so that i am pretty much hitting an in-memory version of the data?

  • Is there any way to pass an anonymous array as an argument in C++?

    - by Jeremy Friesner
    Hi all, I'd like to be able to declare an array as a function argument in C++, as shown in the example code below (which doesn't compile). Is there any way to do this (other than declaring the array separately beforehand)? #include <stdio.h> static void PrintArray(int arrayLen, const int * array) { for (int i=0; i<arrayLen; i++) printf("%i -> %i\n", i, array[i]); } int main(int, char **) { PrintArray(5, {5,6,7,8,9} ); // doesn't compile return 0; }

  • Javascript inheritance: call super-constructor or use prototype chain?

    - by Jeremy S.
    Hi folks, quite recently I read about javascript call usage in MDC https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call one linke of the example shown below, I still don't understand. Why are they using inheritance here like this Prod_dept.prototype = new Product(); is this necessary? Because there is a call to the super-constructor in Prod_dept() anyway, like this Product.call is this just out of common behaviour? When is it better to use call for the super-constructor or use the prototype chain? function Product(name, value){ this.name = name; if(value >= 1000) this.value = 999; else this.value = value; } function Prod_dept(name, value, dept){ this.dept = dept; Product.call(this, name, value); } Prod_dept.prototype = new Product(); // since 5 is less than 1000, value is set cheese = new Prod_dept("feta", 5, "food"); // since 5000 is above 1000, value will be 999 car = new Prod_dept("honda", 5000, "auto"); Thanks for making things clearer

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.

  • C# - Fast and simple multi dimensional data structures?

    - by Jeremy Rudd
    I need to store multi-dimensional data consisting of numbers in a manner thats easy to work with. I'm capturing data in real time, and once processed I would destroy and GC older data. This data structure must be fast so it won't hit my overall app performance. The faster the better. What are my choices in terms of platform supported data structures? I'm using VS 2010. and .NET 4.

  • Removing an object in a child collection in MongoDB

    - by Jeremy B.
    I've got a collection of content. Said collection has a collection of responses as such Content : [{ 'id' : '1234', 'Responses' : [{ 'id' : '12345' } etc. Now, I want to remove response 12345, but I don't want to remove all of the responses. I can't seem to find the command to do so. I'm getting the impression that the correct action is to grab the object, rebuild the Responses without the one I want removed, and then save the Content object as a whole. Provided there are many responses, this seems like a bad practice to have to load the entire object that way.

  • Javascript: Properly Setting A Text Area

    - by Jeremy Person
    I have a text area and the problem is people are typing a large amount of text and I have it clearing out the value and forcing an N/A so I can force something to be entered. How can I make the script below validate someone has already typed something (and not clear it out) but still clear out the N/A by default? textarea name="req_WhatMadeItDifficultToUse" cols="35" onfocus="this.value = '';" onblur="if(this.value == '') this.value = 'N/A';" id="WhatMadeItDifficultToUse"N/A

  • Return http 204 "no content" to client in ASP.NET MVC2

    - by Jeremy Raymond
    In an ASP.net MVC 2 app that I have I want to return a 204 No Content response to a post operation. Current my controller method has a void return type, but this sends back a response to the client as 200 OK with a Content-Length header set to 0. How can I make the response into a 204? [HttpPost] public void DoSomething(string param) { // do some operation with param // now I wish to return a 204 no content response to the user // instead of the 200 OK response }

  • What was the motivation for adding the IPV6_V6ONLY flag?

    - by Jeremy Friesner
    In IPv6 networking, the IPV6_V6ONLY flag is used to ensure that a socket will only use IPv6, and in particular that IPv4-to-IPv6 mapping won't be used for that socket. On many OS's, the IPV6_V6ONLY is not set by default, but on some OS's (e.g. Windows 7), it is set by default. My question is: What was the motivation for introducing this flag? Is there something about IPv4-to-IPv6 mapping that was causing problems, and thus people needed a way to disable it? It would seem to me that if someone didn't want to use IPv4-to-IPv6 mapping, they could simply not specify a IPv4-mapped IPv6 address. What am I missing here?

  • Assembly 6800 Looping? Testing specific bits in a word.

    - by Jeremy
    Hi all, Trying to help a friend out with a friend out with some assembly code, but I've run into a small problem. I'm trying to work out how I would loop through a 8 bit binary word and check the value of specific bits. I need to check bits 1, 3, 5 & 7 to see if they are 1. i.e. int count = 1; int bitAdd = 0; foreach (var bit in word) { if (count = 1 || count = 3 || count = 5 || count = 7) { bitAdd += 1; } count += 1; } Help is much appreciated.

  • How to Vertically Center Images on a Line?

    - by jeremy
    What's the best way to center icons on a line when the images are smaller than the line height? For example (styles inline for easier reading): <div style="line-height: 20px"> <img style="width: 12px; height: 12px;"/> Blah blah blah </div> Here's a jsFiddle example. This example also shows why vertical-align: middle does not work. I want the img to be centered against the text of the div. That is, even if the text wrapped to multiple lines, the image would be centered against a single line. Ideally, the solution would not involve setting margings/paddings on the image and would work even if I didn't know the line-height. Things I've read: How do I vertically align text next to an image with CSS? (deals with case where image is larger, doesn't seem to apply here) Understanding vertical-align

  • If statement String trouble

    - by Jeremy Stone
    I'm trying to create a program which takes user input of two words and determines whether or not these words are the same. import java.util.Scanner; public class L7E3 { public static void main(String[] args) { Scanner keyboard = new Scanner(System. in ); String word1, word2; System.out.println("Please enter a word: "); word1 = keyboard.nextLine(); System.out.println("Please enter a word: "); word2 = keyboard.nextLine(); if (word1 == word2) { System.out.println("The words are " + word1 + " and " + word2 + ". These words are the same."); } else { System.out.println("The words are " + word1 + " and " + word2 + ". These words are not the same."); } } } I figured that word1==word2 would have worked to determine whether the two strings were equal, I'm using JGrasp and it goes directly to my else option regardless of input. Am I doing something wrong with strings?

  • How to style "form" field labels in Windows Phone 7?

    - by Jeremy Bell
    Is there any standards guidance on how to style field labels next to form fields in windows phone 7 silverlight applications? For example, let's say I have a StackPanel with the TextBlock label and a TextBox for data entry. Currently I am using the default TextBlock Margin included in the PhoneTextSubtleStyle ("12,0,12,0"), and using a Margin of "0,-12,0,0" to push the TextBox up closer to the label: <StackPanel HorizontalAlignment="Left"> <TextBlock VerticalAlignment="Center" Text="Name" Style="{StaticResource PhoneTextSubtleStyle}" /> <TextBox Text="{Binding ItemName, Mode=TwoWay}" TextChanged="TextBox_TextChanged" VerticalAlignment="Center" Width="433" Margin="0,-12,0,0" /> </StackPanel> Note that the TextBox seems to have some internal padding of 12 pixels to the left and right, so that the TextBlock label and the TextBox control visually line up perfectly on the left. The problem is, I see existing apps with widely varying conventions for field label styling. Some do not do the negative margin adjustment, like I have above. Some don't. Some appear to override the label TextBlock Margin so that it is indented an additional 12 pixels on the left (i.e. "24,0,12,0" instead of the default "12,0,12,0"). Some apps put the labels to the left of the fields themselves (I hate that). Is there some standard design guidance on field labels in Windows Phone 7? I read through the design template PDF and could only determine that the field labels should be upper case on the first word (preferably only one word labels), and should NOT have a colon at the end. I didn't see anything with regards to margins or alignment between the label and the field.

  • LoadViewState not fired on my user control

    - by Jeremy
    I have a user control nested in a repeater. Inside my user control I have another repeater and in that I have a panel. I am trying to override the LoadViewState event of my user control and dynamically add controls to the panel. I want to do it in the LoadViewState so that the dynamic controls get added before the viewstate gets loaded, so they retain their values after post backs. For some reason the LoadViewState event on the user control (ascx) is not firing. Is there some way to force it to fire, or is there another method I could use? I have ruled out the user controls repeater databind event, because I need it to work even if data binding isn't happening and I can't do it on the repeaters item created event either because the child panel and inner html doesn't exist yet.

  • CakePHP Form Helper - Show error class, but not error message

    - by Jeremy Penrod
    I'm attempting to customize the error output on the CakePHP 2.0 form helper. Currently, the form renders error messages below the input and applies an 'error' class to the input's label. I have found that I can either disable error reporting altogether for an input, or output the error class and message. I would like the error class to be applied to the label of the offending inputs WITHOUT any message below. How do you turn off the error message outputting for a form, BUT still apply error classes to offending labels?
