  • ASP.NET MVC Query Help

    - by Cameron
    I have the following Index method on my app that shows a bunch of articles: public ActionResult Index(String query) { var ArticleQuery = from m in _db.ArticleSet select m; if (!string.IsNullOrEmpty(query)) { ArticleQuery = ArticleQuery.Where(m => m.headline.Contains(query)); } //ArticleQuery = ArticleQuery.OrderBy(m.posted descending); return View(ArticleQuery.ToList()); } It also doubles as a search mechanism by grabbing a query string if it exists. Problem 1.) The OrderBy does not work, what do I need to change it to get it to show the results by posted date in descending order. Problem 2.) I am going to adding a VERY SIMPLE pagination, and therefore only want to show 4 results per page. How would I be best going about this? Thanks EDIT: In addition to problem 2, I'm looking for a simple Helper class solution to implement said pagination into my current code. This ones looks very good (http://weblogs.asp.net/andrewrea/archive/2008/07/01/asp-net-mvc-quot-pager-quot-html-helper.aspx), but how would I implement it into my application. Thanks.

  • Statistics help on 3 choices

    - by DaveSav
    I'm working on an Android app where, at one point, the user is asked to input whether something helped. Their options are 'Yes', 'No' and 'Don't Know'; or they could choose to ignore it. This is for multiple 'somethings' over a date range. A summary view for a date range shows the percentage of 'Yes', 'No' and 'Don't Know' entered for each 'something'. I'm also showing the 'Overall Effectiveness' as the percentage of 'Yes' inputs, which I realise is incorrect. I am thinking of changing that to 'Yes' minus 'No', but that doesn't address the 'Don't Know' inputs. How would I handle the data so that 'Overall Effectiveness' represents all 3 data inputs? So, for a 'something' which has a 'Yes' of 25%, a 'No' of 25% and a 'Don't Know' of 50%, would that be an 'Overall Effectiveness' of 0% ? Or would the 'Don't Know' affect that figure at all? As an additional to that, what graph type, other that Pie, would best display all 3 data?

  • Help translating from assembly to C

    - by user324994
    I have some code from a function subl $24, %esp movl 8(%ebp), %eax cmpl 12(%ebp), %eax Before the code is just the 'ENTER' command and afterwards there's an if statement to return 1 if ebp eax or 0 if it's less. I'm assuming cmpl means compare, but I can't tell what the concrete values are. Can anyone tell me what's happening?

  • LINQ Expression help with Func TEntity,TType

    - by Chris Conway
    I have a repository method that accepts an order by parameter in the form: public IEnumerable<TEntity> Get<TEntity>(Expression<Func<TEntity,string>> orderBy) Now that works fine when trying to sort by a property of type string, var entities = rep.Get(x => x.Name); but what if i want to sort by double or int or any other type. Doing something like var entities = rep.Get(x => x.Price); obviously throws a compile error saying I can't convert double to string. How can I make this more generic so I can sort by any property in my entity, or at least the properties where the type implements IComparable or something similar?

    Hi, I am trying to convert a source from C++ to vb6: C++: static double mdArray[3][3]; static double mdArray2[3][3]; for (i = 0; i < 3; i++) for (j = 0; j < 3; j++) { double sum = 0; for(k = 0; k < 3; k++) sum = sum + mdArray[k][i] * mdArray[k][k]; mdArray2[i][j] = sum } VB6: dim mdArray(0 to 2, 0 to 2) as integer dim mdArray2(0 to 2, 0 to 2) as integer for i = 0 to 2 for j = 0 to 2 dim a as double sum = 0 for k = 0 to 2 sum = sum + mdArray(k,i) * mdArray(k,j) mdArray2(i,j) = sum Next Next Next Will the vb6 version yield the same result as the C++ version? Thanks.

  • please help me to solve problem

    - by davit-datuashvili
    first of all this is not homework and nobody tag it as homewrok i did not understand this porblem can anybody explain me?this is not english problem it is just misunderstanding what problem say Consider the problem of neatly printing a paragraph on a printer. The input text is a sequence of n words of lengths l1 , l2 , . . . , ln , measured in characters. We want to print this paragraph neatly on a number of lines that hold a maximum of M characters each. Our criterion of “neatness” is as follows. If a given line contains words i through j , where i = j , and we leave exactly one space between words, the number of extra space characters at the end of the line is M - j + i -(k=i,k< j,k++) lk , which must be nonnegative so that the words fit on the line. We wish to minimize the sum, over all lines except the last, of the cubes of the numbers of extra space characters at the ends of lines. Give a dynamic-programming algorithm to print a paragraph of n words neatly on a printer. Analyze the running time and space requirements of your algorithm.

  • Need help configuring Castle-Windsor

    - by Jonathas Costa
    I have these base interfaces and providers in one assembly (Assembly1): public interface IEntity { } public interface IDao { } public interface IReadDao<T> : IDao where T : IEntity { IEnumerable<T> GetAll(); } public class NHibernate<T> : IReadDao<T> where T : IEntity { public IEnumerable<T> GetAll() { return new List<T>(); } } And I have this implementation inside another assembly (Assembly2): public class Product : IEntity { public string Code { get; set; } } public interface IProductDao : IReadDao<Product> { IEnumerable<Product> GetByCode(string code); } public class ProductDao : NHibernate<Product>, IProductDao { public IEnumerable<Product> GetByCode(string code) { return new List<Product>(); } } I want to be able to get IRead<Product> and IProductDao from the container. I am using this registration: container.Register( AllTypes.FromAssemblyNamed("Assembly2") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Assembly1") .BasedOn(typeof(IReadDao<>)).WithService.Base()); The IReadDao<Product> works great. The container gives me ProductDao. But if I try to get IProductDao, the container throws ComponentNotFoundException. How can I correctly configure the registration?

  • Need some help understanding a weird C behavior

    - by mike
    This part of my code works fine: #include <stdio.h> int main(){ //char somestring[3] = "abc"; int i, j; int count = 5; for((i=0) && (j=0); count > 0; i++ && j++){ printf("i = %d and j = %d\n", i, j); count--; } return 0; } The output as expected: i : 0 and j : 0 i : 1 and j : 1 i : 2 and j : 2 i : 3 and j : 3 i : 4 and j : 4 Things get weird when I uncomment the char string declaration on the first line of the function body. #include <stdio.h> int main(){ char somestring[3] = "abc"; ... } The output: i : 0 and j : 4195392 i : 1 and j : 4195393 i : 2 and j : 4195394 i : 3 and j : 4195395 i : 4 and j : 4195396 What's the logic behind this? I'm using gcc 4.4.1 on Ubuntu 9.10.

  • Need help with transferring data between MySQL db's using PHP

    - by JM4
    In one of the sites I manage, the client has decided to take on ACH/Bank Account administration where it was previously outsourced. As a result, the information submitted in our online form which used to simply store in a single database for processing now must sit in 'limbo' until the funds used for payment have been verified. My original plan is as follows: At the end of an enrollment, all form data is collected and stored in a single MySQL database. Our internal administrator will receive an email notification reminding him enrollments have taken place. He will process the ACH information collected and wait the 3-4 business days needed for payment to clear. Once the payment information has been returned as Good (haven't considered what I will do with the 'bad' yet), the administrator can log into a secure portal which allows him to click a button to 'process' the full information once compared and verified. the process is simplified as: Enrollment complete: data stored in DB 'A' Funds verified and link clicked: data from 'A' is copied to DB 'B' and 'A' is deleted. I have run similar processes with CSV output before and simply used //transfers old data to archive $transfer = mysql_query('INSERT INTO '.$archive.' SELECT * FROM '.$table) or die(mysql_error()); //empties existing table $query = mysql_query('TRUNCATE TABLE '.$table) or die(mysql_error()); but in those cases, ALL data returned was copied and deleted. I only want to copy and delete a single record. Any idea how to accomplish this?

  • in_array() - help on what specifically would return true

    - by Kerri
    I am using in_array, and I'm trying to use it in a way where it will only return true if it's an exact match of one of the objects in the array, not just if it's "in" the array. e.g. 1. $sample_array = array('123', '234', '345'); 2. $sample_array = array('23', '34', '45'); in_array('23', $sample_array); In the above example, I would only want version 2 to return true, because it has the exact string, '23'. Version 1 returns true as well though, because the array contains instances of the string '23'. How would I get this to work so that only version 2 returns true? Am I even using the right function?

  • Help constructing query - Compare columns and replace numbers

    - by Tommy
    I have a feeling that this query is pretty easy to construct, I just can't figure it out. I want to replace all numbers in table X column C, with numbers in table Z column A, where numbers from table X column C matches numbers in table Z column B. I hope that makes sense. Perhaps a little background information will make it clearer. I've converted from one CMS to another, and the module I used to convert mapped the ids to the new database. Table X column A is the new id's. Table X column B is the old id's. Table Z is the table for an image gallery that I migrated, and column C contains the id's of the images owners. Can anyone crack this nut?

  • need help with some basic java.

    - by Racket
    Hi, I'm doing the first chapter exercises on my Java book and I have been stuck for a problem for a while now. I'll print the question, prompt/read a double value representing a monetary amount. Then determine the fewest number of each bill and coin needed to represent that amount, starting with the highest (assume that a ten dollar bill is the maximum size needed). For example, if the value entered is 47,63 (forty-seven dollars and sixty-three cents), and the program should print the equivalent amount as: 4 ten dollar bills 1 five dollar bills 2 one dollar bills 2 quarters 1 dimes 0 nickels 3 pennies" etc. I'm doing an example exactly as they said in order to get an idea, as you will see in the code. Nevertheless, I managed to print 4 dollars, and I can't figure out how to get "1 five dollar", only 7 dollars (see code). Please, don't do the whole code for me. I just need some advice in regards to what I said. Thank you. import java.util.Scanner; public class PP29 { public static void main (String[] args) { Scanner sc = new Scanner (System.in); int amount; double value; double test1; double quarter; System.out.println("Enter \"double\" value: "); value = sc.nextDouble(); amount = (int) value / 10; // 47,63 / 10 = 4. int amount2 = (int) value % 10; // 47 - 40 = 7 quarter = value * 100; // 47,63 * 100 = 4736 int sum = (int) quarter % 100; // 4763 / 100 => 4763-4700 = 63. System.out.println(amount); System.out.println(amount2); } }

  • Need help with text animation within UITableViewCell

    - by gdiphone
    I'm trying to implement a simple text animation in a custom UITableViewCell without having to go into editing mode which automatically brings up the delete button on the right. What I'm trying to accomplish is that when the label is updated by a button within the UITableviewcell, the text in the label is updated but with some smooth animation like sliding to the right since the updated text is prepended to the string. Any sample code would be great. thanks
