i mean when i write the code in the coding window it's always in english.
Have you install those language i your machine? If yes, then simply choose the language from taskbar when you are in coding window. How do you type them in MS Word? And after that you have to SAVE AS it as Unicode Encoding, UTF-8 .

First, as Mazdak said, you have to have the fonts (not characters) installed on your system. Many of the OpenType fonts like Arial, Verdana, and Times already have the full Unicode character set supported (at least at the time of their release).
You can further write your applications in your native language (known as the neutral language - the resources that are compiled into your primary assembly) and have other languages - not just text but layouts and other settings as well - in satellite assemblies. In you look in the .NET Framework SDK documentation, there's an entire section didicated to localizing applications, including some examples (though most of this can be done in the VS.NET designer if you like that sort of thing - just see the Localized and Language properties of the Form that's open in the designer).
See Developing World-ready Applications[^] in the .NET Framework SDK for more information, especially the section, Resources in Applications[^].

Hello, i used to develop my Web applications using the well know way.. Data layer, dataprovider class, bussiness layer, interface layer.. the dataprovider class is like this:
public class DataProvider
{
public void AddItem(Item item)
{
// SQL COMMANDS
}
public Item GetItem(int itemID)
{
// SQL Commands
return item;
}
}
the bussiness layer would look like this:
public class Item
{
int _itemID;
int _itemName;
int _blahBlah;
// properties
}
public class Items
{
public void AddNew(Item item)
{
DataProvider.AddItem(item);
}
public Item Get(int itemID)
{
Item item = DataProvider.GetItem(itemID);
return item;
}
}
well,, that was nice and lovely.. everything was ok,, until i had to do a windows Forms application... which i am not familiar with 
the app i'm doing is kinda complicated.. its for a school. and i have to take care of students, subjects, administrators.. and so on therefore, if i use the old way i used to use in my web application.. i think i will have problems,, coz i will use alot of DataGrids..
Simply, i don't know what to do at all
i know about DataSet, but i don't know how to use it and n-tier application,, how to design the classes to deal with DataSets. should i do the old way but return datasets instead of particular objects "like Item for example", what the #$#$ should i do.. i'm really lost... Can u please help me
i just need to know how to design the layers.. just hints.. or main concept for designing classes that deals with DataSet...
thanx

i saw a sample in MSDN, it wasn't helpful.. i need suggestions
|
|
|
|
|
download thr trial al oloero, or llblgen and check out the samples. They use Collections or ArrayLists as "dataset" and classes that represent a table in the databases.

DataSets are like disconnected-recordsets, but they can track relationships, enforce constrains, and contains different Types. The best way to understand these is read the documentation for the DataSet class and its members. There's also a section on ADO.NET with DataSets in the .NET Framework SDK that you should read. Don't just look at one example on MSDN and call it quits.
When you create a strongly-typed DataSet, you can refer to tables and columns by name. Strongly-typed DataSets also perform better before columns (when identitied by name) are faster to resolve (fewer look-ups are required, and indexes are cached).
You can easily bind these to controls in Windows Forms and ASP.NET controls. You could use this logic in both environments.

not sure if this is the best forum for this...
i am trying to figure out how to set the "application icon" for my C# winforms project, (ie the icon you see from explorer, etc)
at one point it was the same as the main form's icon, but no longer...
i cannot find anywhere in VS.net to set this, i am pretty sure there is a compiler flag i can use,something like /w32icon but i would like to remain in VS.net if possible
Thanks for any help

msdn claims there is a general property page under "common" properties....
perhaps this is not included in VS.net 2002?
i suppose i can compile from commandline for release builds... just kind of a big nuisance

Try right clicking on the project and selecting "Properties". The option should appear in the window that opens up.

How do I declare a string array and give it a value? This is what I have, what do I need to change? It says I need a "]" after the one.
public string[] strGeoq = new string[30];
strAnimalsq[1] = "Blah Blah Blah";
|
|
|
|
|
public string [] sValue = new string[10];
sValue[1]="your value";
|
|
|
|
|
I just tried with, with the space between string and the brackets; it didn't work.

Is this your sig or the error code?

Assuming this is your code as it is now
class Test
{
public Test()
{
}
public string[] strGeoq = new string[30];
strGeoq[1] = "Blah Blah Blah";
}
It can't be done that way, it would have to be something like this
class Test
{
public Test()
{
}
public string[] strGeoq = new string[30];
public void Init()
{
strGeoq[1] = "Blah Blah Blah";
}
}
or
class Test
{
public Test()
{
}
public string[] strGeoq = {"Blah, Blah, Blah", "Another Blah", etc"};
}

ok i have this case and try almost everething and dont work ..
C++ Dll:
typedef BYTE *CCSTR;
CCSTR __stdcall Example(CCSTR data)
{
//do somthing
}
C#:
[DllImport("test.dll",CharSet=CharSet.Auto,
CallingConvention=CallingConvention.StdCall)]
static public extern string Example([MarshalAs(UnmanagedType.LPStr)] string Data) ;
if someone have idea what can be wrong that will be very cool
10x in advance
PS: Sry about my bad english

no error just dont retutn anything

You have CharSet set to CharSet.Auto, but your typedef clearly shows that only an ANSI string (single byte) would be supported. Set CharSet to CharSet.Ansi.

Why don't you post some code. This can work and I've done it successfully in the past. You either pin the addresses yourself or use one of the methods from the System.Runtime.InteropServices.Marshal class, though you're limited in what you can do with them. All ths has to be done from within a safe context, unless you use the methods from the Marshal class and use IntPtr for the pointer fields in your struct.
EDIT: Wrong reply - mistook for a different P/Invoke thread today.

in VB this is defined like
Public Declare Function decode Lib "endecode.dll" (ByVal Data As String) As String
in C#
[DllImport("endecode.dll",CharSet=CharSet.ASCII,<br />
CallingConvention=CallingConvention.StdCall)]<br />
static public extern string decode ([MarshalAs(UnmanagedType.LPStr)] string Data) ;
but dont work

Next time, please use the <pre> tags around your code.
If it won't compile, that's because ASCII is not an enumeration member of the CharSet enum. The compiler error would tell you this.
Also, the endecode.dll library must be in your PATH environment variable somewhere (like %WINDIR%\ and %WINDIR%\System32, etc.), or in the application directory (from where the application is run, or whatever is set to the working directory). P/Invoking code from an unmanaged DLL requires that the DLL can still be found. In this case, usually, you'll get a FileNotFoundException or some other runtime exception.
Since your VB code works, there's really no reason to post your C/C++ code.
