Hi there i want to create node to make the Half man Tree The code that i found to make node is here
<pre lang="c#">
public class Node
{
public char Symbol { get; set; }
public int Frequency { get; set; }
public Node Right { get; set; }
public Node Left { get; set; }
public List<bool> Traverse(char symbol, List<bool> data)
{
// Leaf
if (Right == null && Left == null)
{
if (symbol.Equals(this.Symbol))
{
return data;
}
else
{
return null;
}
}
else
{
List<bool> left = null;
List<bool> right = null;
if (Left != null)
{
List<bool> leftPath = new List<bool>();
leftPath.AddRange(data);
leftPath.Add(false);
left = Left.Traverse(symbol, leftPath);
}
if (Right != null)
{
List<bool> rightPath = new List<bool>();
rightPath.AddRange(data);
rightPath.Add(true);
right = Right.Traverse(symbol, rightPath);
}
if (left != null)
{
return left;
}
else
{
return right;
}
}
}
}
</pre>
I know that the Symbol and Frequency Are the data and the Left and Right is to store the position of the another Node. but i dont understand the Traverse Method. what is for!!!
The Rest of the halff man code is here:
<pre lang="c#">
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
namespace HuffmanTest
{
public class HuffmanTree
{

public Node Root { get; set; }
public Dictionary<char, int> Frequencies = new Dictionary<char, int>();
public void Build(string source)
{
for (int i = 0; i < source.Length; i++)
{
if (!Frequencies.ContainsKey(source[i]))
{
Frequencies.Add(source[i], 0);
}
Frequencies[source[i]]++;
}
foreach (KeyValuePair<char, int> symbol in Frequencies)
{
nodes.Add(new Node() { Symbol = symbol.Key, Frequency = symbol.Value });
}
while (nodes.Count > 1)
{
List<Node> orderedNodes = nodes.OrderBy(node => node.Frequency).ToList<Node>();
if (orderedNodes.Count >= 2)
{
// Take first two items
List<Node> taken = orderedNodes.Take(2).ToList<Node>();
// Create a parent node by combining the frequencies
Node parent = new Node()
{
Symbol = '*',
Frequency = taken[0].Frequency + taken[1].Frequency,
Left = taken[0],
Right = taken[1]
};
nodes.Remove(taken[0]);
nodes.Remove(taken[1]);
nodes.Add(parent);
}
this.Root = nodes.FirstOrDefault();
}
}
public BitArray Encode(string source)
{
List<bool> encodedSource = new List<bool>();
for (int i = 0; i < source.Length; i++)
{
List<bool> encodedSymbol = this.Root.Traverse(source[i], new List<bool>());
encodedSource.AddRange(encodedSymbol);
}
BitArray bits = new BitArray(encodedSource.ToArray());
return bits;
}
public string Decode(BitArray bits)
{
Node current = this.Root;
string decoded = "";
foreach (bool bit in bits)
{
if (bit)
{
if (current.Right != null)
{
current = current.Right;
}
}
else
{
if (current.Left != null)
{
current = current.Left;
}
}
if (IsLeaf(current))
{
decoded += current.Symbol;
current = this.Root;
}

I have a question about the benefits of using linq to sql in a C# 2010 web application. I am asking that question since I am the only programmer at a small company that is making changes to the company website that was written originally by a contract shop that went out of business. This is the first time I have worked with linq to sql.
From my point of view, I just see linq as more performance overhead to slow down the performance of the website. The linq needs to be translated to sql by the .net application. Thus can you tell me what I am missing?
|
|
|
|
|
In a lot of cases, a well designed LINQ application is no less performant than a hand crafted SQL solution. You have to be aware of what you are doing, but when you do know, it's a pretty powerful technique.
|
|
|
|
|
Neh. The peformance is similar to hand rolling the code against SQL directly, but (as Pete has said) you need to know what you are doing. You can use SQL Queries, with LINQ to SQL, and the queries can be optimised in the usual way.
What is does bring in the ability not to need write yet another DAL Implementation, freeing you up to be more productive in other areas. I've not really used ADO.NET directly for a good few years now, nor have I felt the need to.

Hi,
If you can utilize LINQ perfectly then linq to sql will definitely improve your application performance. One more advantage is database dependency. you can provide multiple database support for your application like MySQL, MsSQL, etc....
You do not need to maintain two database query individually. Framework will manage that.
There are more features and both way have pros and cons. so you need to decide it from your application requirements.
Thanks

Bold statement there. It MAY improve application performance, but if I write equally optimised SQL then I won't see an improvement.

Yes but my personal opinion is if we are with the latest trend or flow of the Microsoft evolution then we can win the race. As we can see Microsoft people concentrate on new things, so if you are planning for long term project then we should use latest one.
As good coding in Framework 2.0 is better then Bad in Framework 4.0 
But i would like to know your personal opinion, if you have a long term project what will be your choice ?

on codeplex it says this project is in progress. so can we rely on that ?
|
|
|
|

Yes. The in progress part means we are adding lots of new features to it - this really is an ongoing project. It's actually up and running here[^].

First, you don't call "values", so we have no idea what you're trying to do.
Second, you only post the RELEVENT code snippets, not your entire frickin' project. I'm not in the mood to read that massive amount of code.

I second that, as I'm never in the mood to read the irrelevant code.

Hi, anyone knows a .NET component/library that can provide me certain informations about media files:
For video I would need :
- codec name
- Image size (resolution)
- duration
- format
- frame rate
- aspect ratio
- bit rate
Audio :
- duration
- codec name
- sampling rate
- channel no
- bit rate
Thank you in advance!

Actually im getting error when the below code is executed from unit test project...
where import is an xml file in the below code..
XmlTextReader importReader= new XmlTextReader(System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import"));
the above code is present in one of the methods in different project(class library) which is used in test method in the unit test project
where as the above path is present in web project.
and the value of the
System.Web.Hosting.HostingEnvironment.MapPath("~/Content/Importcontent/import")
is null..ie unable to get the complete path of the file i guess bcos the hostingenvironment is not running(web project)
The above code is working fine when running from the webproject ie it returns the exact path.
whereas returning null value when running from test project.
please let me know how to fetch the file path(where file is present in web project) when running from test project.

You shouldn't be trying to read files out of your live project in the unit tests. That's, well, not a unit test
|
|
|
|
|
Hi,
if you have a file to read in Unit test then you need your file in OUT folder. You need to add those files as DeploymentItem list(.testsettings file >> deployment submenu). you can add Deployment item from testsetting file or by adding class decoration.
like,
[DeploymentItem("Content/Importcontent/import")]
after doing one of the above procedure, you can access your file. one more important note : make sure your file property "Copy To Output directory" = Copy Always
Thanks
