Often when you have a problem that looks like "I need a data structure that has the properties of A and of B" where A and B are some data structure, there's an obvious way to just combine A and B and wrap them a little thing that keeps them synchronized.
Such as here, it looks like a List and like a Dictionary.. what can you do? Well you can make a List<Tvalue> and a Dictionary<Tkey, int> and let the dictionary map keys to indexes in the list.
If you also want removal, you can use a linked list instead of a list, and let the dictionary map keys to nodes in the linked list.

Hi Harold,

Upvoted, as usual: why is it that when I read your comments, I often feel like I am listening to Yoda trying to tell me something through metaphor that's just beyond my ability to grasp ? Smile | :)

Hi

I'm developing a wpf application using visual studio 2010 in c#.
for security reason, the navigation in the operating system is not allowed while running the application.
That means once it is launched, all Windows menu, icons, toolbars ... must be hidden, and only the application must appear.
(it's a kind of that the PC becomes only dedicated to it).

Any suggestion or Idea ?

Thanks in advance

I don't have any code but what I think you might want to look into is running the application in what is known as 'kiosk' mode.

Sounds like what you want is a "kiosk" mode kinda thing.

If so, you should add WindowStyle="None" and WindowState="Maximized" to the XAML of your main window. Further, you can even disable resizing and make it be the windows at the top from the start, adding ResizeMode="NoResize" and Topmost="True". Code would look like this:

XML

<Window x:Class="WpfApplicationTest1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"
        WindowStyle="None"
        WindowState="Maximized"
        ResizeMode="NoResize"
        Topmost="True">

Note that Windows keyboard shortcuts still work (Alt+Tab, Windows Key, Alt+F4). If you want to "disable" those, you will have to capture them, although opening applications in this manner (for example Windows+E for Windows Explorer) won't display the newly opened application since yours is Topmost as set in the property.

[EDIT]
The same can be achieved modifying those properties in the constructor, like so:

namespace WpfApplicationTest1
{
  public partial class MainWindow : Window
  {
    public MainWindow()
    {
      InitializeComponent();
      WindowStyle = WindowStyle.None;
      WindowState = WindowState.Maximized;
      ResizeMode = ResizeMode.NoResize;
      Topmost = true;
    }
  }
}

I don't think, you can do this. And even if you did, the user could still press Ctrl + Alt + Del (which can't be intercepted as far as I know), open Task Manager and kill your application.

I would suggest another appoach. Give the user only minimal rights (just to his user directory). Start your application under a different user who has access to the necessary directories. Require a password to close your application. Under this setup the Task Manager is of no use because the user can't kill other users' processes.

The good thing about pessimism is, that you are always either right or pleasently surprised.

First, the mandatory question since you don't mention it in your post:

What have you tried?
I remember I did something kind of like what you want about a year ago, since I didn't have a clue, I googled (don't remember the specific query), and one of the first links was a MSDN page with an example to it.

What I mean is: please show/tell us what you've done, and what is the specific problem that you have, so we know that you are indeed making an effort and not just wasting everyone's time.

Now, I'm not just gonna lecture you and give you nothing. Look for info on:

How to read/write files in C#
How to get the HTML contents of a web page

You'll need to get acquainted with the following namespaces/classes:
System.Net[^]

Dynamic Columns in Entity Framework

Hi All,

I have created a stored procedure which returns dynamic columns, i need to map this to the EF to populate the data on a KendoUI Grid. How can i do it?

I need to create the entities based on the number of columns returned from the stored procedure, because my columns are always dynamic and change frequently, so i cannot create a fixed custom entity in EF.

if I have used Normal Ado.net it will return datatable format.In this we can't bind kendoui using Datatable.

Any help would be appreciated Please respond ASAP.

If by "do the needful" you mean write your code for you, that's just not going to happen.

You haven't said anything at all about where you're stuck in this process, so it's pretty much impossible to tell you what's going on.

Dave, fyi, the expression "do the needful" is a Hindi-English idiom often used in correspondence; in this case it may not have the meaning of "gimme codez" ... or, it might Smile | :)

I know where it's from and it can be traced back to about the 1700's in British English.

But, since the OP doesn't specify anything at all about what he's looking for, I just had to guess and us an "if" in preface to the most likely possibility.

Hi Dave,

I am delighted to know you are familiar with such constructions (the more common form, I believe, is "do the necessary") [^]. I'm not sure whether, technically, these (now archaic) forms qualify as calques, and/or Anglicisms.
