Dear Sid,
I am using this piece of code in thread.It tells me when client is connected and send data to me.
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 8001);
listener.Bind(endpoint);
listener.Blocking = true;
listener.Listen(0);
Socket objSock = listener.Accept();
objSock.Receive(ReceiveData);
objSock.Shutdown(SocketShutdown.Both);
listener.Close();

Hi,
I have learned how to load language specific string from sattelite assemblies by changing the CultureInfo of the Resource's typed class accessor. Now, I am wondering how can I set the culture specific language for the Microsoft's built in UI. For example, I want to change the language of the TextBox's context menu (Cut, Copy, Paste) as there is no "culture" property available for the class Control. Would you please give me any idea.
Thanks

use System.Globalization,
There, you will get Cultureinfo and RegionInfo Class.
just go through this.
you can also build custome culture using CultureAndRegionBuilder Class!!!

I'm trying to design my user interface where the user can change the background/foreground colors according to their preference. The XML file format appears to be the best and I would like any advice on making it as effecient as possible. The file's contents could change multiple times (re-written). Is overwriting XML file a good idea. Is there a better file format?
Thanks guys!
may your code be error free.
(okay, maybe two lines.)

For reading and writing XML files, you can use XMLDocument class which provides a DOM model for the supplied XML file. This class provides methods for creating new node/attributes etc. For reading XML files efficiently, use XPath.

Thanks for the info. It will get me jump started. The more I look into XML, the more convinced I am that it's my best option. Some of the replies to this thread thought I was intending on the user writing the strings by hand 
My opinion of user interaction with text is to limit the use of a textbox AS MUCH as possible! When the user gets a hold of a textbox that will be inputting critical data, bad things will start happening if serious validation is not done.
Best wishes to your code!

Depends on what you mean by 'better'.
Of course it is OK to overwrite an XML file. But if you want files that can be hand-edited by the user (think Notepad), .properties files are the way to go.
Cheers,
Vikram.

What is properties file ?

Very common in Javaland. Instead of angle brackets, they simply use the equals sign. Example:
dbServer=SERVERNAME
userName=user1 To the lay user, editing these in Notepad is much easier than editing XML files.

That's fine. Is this commonly used in .NET ?

Why not use the standard .NET Profile Provider? It's not just for ASP.NET.

I have a windows application in C#. On click of a button i want to open windows Explore and navigate to one folder. How can i do that?
|
|
|
|
|
System.Diagnostics.Process.Start("C:\\Inetpub");
|
|
|
|
|
This should work for you:
System.Diagnostics.Process.Start(@"explorer.exe", @"C:\Windows");

I think you can write custom actions when creating installation package. This[^] blogs says something similar.

can you elaborate on this?
|

|
|

as u said u r making your application in c# and hopefully for that u r using visual studio.
so in that same Visual studio there's a new project type "setup wizard" or "setup project" make your setup and when u done with it... there a option in that setup project with the name of Registry editor. u can add your required registry keys there.
