Augmented Reality in flash

I was working on flex programming with papervision for some time. Suddenly I came across a new method known as Augmented reality. It is for adding virtual objects in real world video. you can add MD2 Models on it. I have downloaded and played around it. FLARToolkit library is used to build it. Here i will list some of interesting links that i found

Later I will try to correct errors in the articles

Sorry for bad english.

Traversing and adding file structure to a tree node

using System.Drawing;
using System.Text;
using System.Threading;
using System.IO;
public void ListDir(string src, TreeNode d){
try{
DirectoryInfo dinfo = new DirectoryInfo(@"" + src);
FileInfo[] finfo = dinfo.GetFiles();
for (int j = 0; j < finfo.Length; j++)
{
d.Nodes.Add(@"" + finfo[j].Name);
}

DirectoryInfo[] dname = dinfo.GetDirectories();
TreeNode[] treend = new TreeNode[dname.Length];
for (int i = 0; i < dname.Length; i++)
{
treend[i] = new TreeNode(dname[i].Name);
d.Nodes.Add(treend[i]);
}
for (int i = 0; i < dname.Length; i++)
{
ListDir(dname[i].FullName, treend[i]);
Thread.Sleep(5);
}
}

Listing Logical Drives

DriveInfo[] dinf = DriveInfo.GetDrives();
int i = 0;
while (i < dinf.Length)
{
MessageBox.show(dinf[i]);
}

Create XML file using C#

Namespaces

using System.Data;
using System.Drawing;
using System.Xml;
using System.IO;

//code

XmlTextWriter xmlWriter = new XmlTextWriter("temp.xml", System.Text.Encoding.UTF8);
xmlWriter.Formatting = Formatting.Indented;
xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'");
xmlWriter.WriteStartElement("root");
xmlWriter.Close();
// creation complete

doc = new XmlDocument();
doc.Load("temp.xml");
XmlNode newNode = doc.CreateNode(XmlNodeType.Element, "firstnode", ""); // creating Node
newNode.InnerText = “Content”; // set your content
doc.DocumentElement.AppendChild(newNode); //Adds a Node
doc.Save("temp.xml");

Dynamically add Picture box using C# delegate

The below code is just abstract just to show simple use of delegate

using System.Data;

using System.IO;
using System.Drawing;
using System.Text;
using System.Threading;
public partial class ImageView : Form{

Mydel a;

public delegate void Mydel(PictureBox p);
public ImageView(){
InitializeComponent();
}

private void ImageView_Load(object sender, EventArgs e){
a = new Mydel(Add);
Thread t = new Thread(load);
t.Start();
}

public void load(){

DirectoryInfo dinfo = new DirectoryInfo(@"F:\Mypics");
FileInfo[] finfo = dinfo.GetFiles();
Graphics g = panel1.CreateGraphics();
int x = 20;
int y = 20;
for (int i = 0; i

if (Image.FromFile(finfo[i].FullName) != null){

PictureBox p = new PictureBox();
p.Image = Image.FromFile(finfo[i].FullName);
p.SizeMode = PictureBoxSizeMode.StretchImage;
p.Left = x;
p.Top = y;
p.ImageLocation = finfo[i].FullName;
p.Width = 140;
p.Height = 90;
Object[] obj = new Object[1];
obj[0] = p;

Controls[Controls.IndexOf(panel1)].Invoke(a, obj);
x += 150;

if (x > this.Width-100){

y += 100;
x = 20;
}

}
if (i > 35)
break;

}

}

public void Add(PictureBox p) {

panel1.Controls.Add(p);

}

}

}

Function to retrieve RAM SIZE in MB C#

This is the sample code to retrieve total ram size of system using WMI (Windows Management Instrumentation) well it’s not perfect but it works

Name spaces

using System;
using System.Management;
using System.Collections.Generic;
using System.Text;

public int getRAMSize() {
int total=0;
try
{
ConnectionOptions connection = new ConnectionOptions();
ManagementScope scope;
scope = new ManagementScope("root\\CIMV2", connection);
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_ComputerSystem");
ManagementObjectSearcher searcher =new ManagementObjectSearcher(scope, query);
foreach (ManagementObject queryObj in searcher.Get(){

total = Convert.ToInt32(queryObj["TotalPhysicalMemory"].ToString());
}

total = total / 1024;
}

catch {} }

return total;

}

Welcome to my Blog

Hai all I am abhilash,
software student from India. I am onto programming from quite a time now. Then one day I suddenly thought about start blogging. So that I can share with you all whatever I know. I will try to give small code samples and all but I am not guaranteeing its correctness because still I am studying and I am careless and less worries about implementation. All the code given are simple and abstract . But I am sure even beginners can figure out what I ment, You can use the code at your own risk.
