Graduated

I have graduated from Mathematical engineering at Yıldız technical university. It was good to be a student after 4.5 years. I established good friendships from here and I cant estimate the price for this. I would like to say thanks very much to all my teachers and supervisors and friends.

hehe congratulations to me Smile

Setting culture at page and codebehind

Setting culture with C#
protected override void InitializeCulture()
{
if (Request.Form["DropDownList1"] != null)
{
// Define the language
UICulture = Request.Form["DropDownList1"];
// Define the formatting (requires a specific culture)
Culture = Request.Form("DropDownList1");
}
base.InitializeCulture();
}

Also if you want to do this setting from page without dont write anything in c# code you can just write this top of the page
<%@ Page UICulture="es" Culture="es-MX" %>

Create Dynamic Master Page

if you want create your dynamic masterpage in your website you can just use this kind of codepart at your code.

Session["masterpage"] = "Master2.master";
Response.Redirect(Request.Url.ToString());

void Page_PreInit(Object sender, EventArgs e)
{
if (Session["masterpage"] != null)
MasterPageFile = (String)Session["masterpage"];
}

Using the XPathNavigator to Search XPathDocuments

protected void Button8_Click(object sender, EventArgs e)
{
lbl = GetLabel(275, 20);
string s;
XPathDocument xmlDoc = new XPathDocument(MapPath("iboxml.xml"));
XPathNavigator nav = xmlDoc.CreateNavigator();
string expr = "//myChild[@ChildID='ref-3']";
//Display the selection
XPathNodeIterator iterator = nav.Select(expr);
XPathNavigator navResult = iterator.Current;
while (iterator.MoveNext())
{
s = String.Format("Type:{0} Name:{1} ",navResult.NodeType, navResult.Name);
if (navResult.HasAttributes)
{
navResult.MoveToFirstAttribute();
s += "Attr: ";
do
{
s += String.Format("{0}={1} ",navResult.Name, navResult.Value);
}
while (navResult.MoveToNextAttribute());
}
lbl.Text += s + " ";
}
}

Solving "The project file ' ' has been renamed or is no longer in the solution"

We were recently faced with the error message The project file ' ' has been renamed or is no longer in the solution in Visual Studio 2008. The problem is that from this message you have no idea what is actually the matter. We finally figured out that this happens when a Web Project contains references to assemblies or projects it can't find. Here's how you solve this:

Right click the Web project and select Property Pages.

A window will open which lists all the references, either to the bin-folder, GAC or other projects in the solution.

(unavailable)

Chances are that now you can't build because the reference is not there. Simply add the reference again and you should be OK

Windows Identy / Windows Principal

User identity is a common means of controlling access to a business application or limiting the options available within that application. The .NET Framework classes under the namespace System.Security.Principal are provided to assist in making such role-based security determinations.

*firstly you must add this dll :
System.Security.Principal; System.Security.Policy;
then:
The Framework provides a WindowsIdentity class that represents an authenticated Windows user and a WindowsPrincipal class that encapsulates the WindowsIdentity and information about the user's role memberships. These objects representing the current user are accessible in one of two ways: using a static property on the Thread object or a static method on the WindowsIdentity object.
you can see example of windows identity and windows principal ;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            WindowsIdentity kimlik = WindowsIdentity.GetCurrent();
            Console.WriteLine(kimlik.Name.ToString());
            Console.WriteLine(kimlik.Token.ToString());
            Console.WriteLine(kimlik.AuthenticationType.ToString());

            if (kimlik.IsAnonymous)
                Console.WriteLine("Genel kullanıcı");
            if (kimlik.IsGuest)
                Console.WriteLine("Misafir kullancı");

            kimlik = WindowsIdentity.GetCurrent();
            WindowsPrincipal kimlik2 = new WindowsPrincipal(kimlik);
            Console.WriteLine(WindowsBuiltInRole.Administrator);
            kimlik2.IsInRole(WindowsBuiltInRole.Administrator);
            Console.ReadLine();

}
}
}

you will see like this when you run your code ….

Make your own Tcp Server/ Client

In this tutorial I’m going to show you how to make a tcp server with C#. If you ever work with windows’ sockets , you already know how difficult this can sometimes be. However you can see how it can be easy in .net platform.

* firstly you must add which name space you need for network programming.
using System.Net;
using System.Net.Sockets;
And then you can write this code ;


Now Just start to explain our code.In main function you just define your class instance which name is Initialize and use it’s method which is called StartListen.And in this method we just called the StartStream method firstly.
At the StartStream method our first work is defining our variable.After this We must send parameter to TcpListener object what it needs.
*newsock = new TcpListener(IPAddress.Any, Convert.ToInt32(port));    => here we define ip adres and port for listener.
*newsock.Start();   => Just started our TcpListener.
*client = newsock.AcceptTcpClient();   => this code part is blocking until a client is connected to the server and accepts a pending connection request.
*ns = client.GetStream();   => set our networkStream to send or receive data.
* In the StartListen method, you define byte array and use networkstream write method.
byte[] dizi = Encoding.ASCII.GetBytes(LA);
ns.Write(dizi, 0, dizi.Length);

Attention ! please dont forget to close your stream after all works are over.Like these =>    newsock.Stop(); client.Close(); ns.close();

At client side, you can use this code block for read data from tcpserver. And you can find explanation about every statement why we use it.

byte [] data = new byte[1024];
//this line is about reading data from networkstream
// and just for learning to find how many byte we use in array which name is ‘data’
recv = ns.Read(data, 0, data.Length);
//at here, we convert our data type byte to string
string ss = Encoding.ASCII.GetString(data, 0, recv);
// after this line you can do what you want …

Get data from xml file

Today I decided to write my article about xml , firstly I want to say somethink about my grammar ,this is my first article that I use english so I m sory if I make mistake. :))

*Why we use xml file ?
*because in the real world, computer systems and databases contain data in incompatible formats.XML data is stored in plain text format. This provides a software- and hardware-independent way of storing data.This makes it much easier to create data that different applications can share.

XmlTextReader xmlDocument = new XmlTextReader("MyXmlFile.xml");

                while (xmlDocument.Read())
                {
                    if (xmlDocument.NodeType == XmlNodeType.Element)
                    {
                        switch (xmlDocument.Name)
                        {
                            case "ip":
                                _IpAdres = Convert.ToString(xmlDocument.ReadString());
                                break;
                        }
                    }
                }
                xmlDocument.Close();

Console.WriteLine(IpAdres );

*XmlTextReader xmlDocument = new XmlTextReader("TcpServer.xml");
At this sentence you just defined your stream for reading xml and set it’s parameter which is about file path .
*while (xmlDocument.Read()) after defined your stream, you can start reading the first line of your file
*xmlDocument.NodeType == XmlNodeType.Element At this part of code you just verify your node type for sure it not root node. And then you can use switch to take your node name .
* when you found which name you search you could read that line and convert which type you want same this => _IpAdres = Convert.ToString(xmlDocument.ReadString());
