DNS Records:
We have many different type of DNS records and most of these record types are not commonly used. By the way you need to know a little about these

- NS: is name server which specifies a name server for the domain.

- CNAME: Sets an alias for a host name. Like "docs >> CNAME >> ghs.google.com. >> 0 >> 3600" in here means: forward docs.domain.com to custom google document server in behind scene.

- A: Maps a host name to an IP address
- MX: is Mail eXchanger.
- TXT: it's strictly informational.

Solution:
- Login to dns-diy.net in here or any domain control panel
- Find a custom DNS Records Zone (its first page which comes after login)
- Add a new record with
host: 
type: NS
data: ns.yourhost.com
priority: 0
ttl: 3600
- Click update and wait for minutes for works ;-)

DNS-DIY Zone Edit

Test:
If you'd like to check the status of your DNS records for web publishing, you can perform a free nslookup. Here's how:
- Google NS lookup [link].
- Select a search result from top of list.
- Type your domain address in to the field.
- Click Submit, or Lookup.

- Microsoft Visual C++ 2010 (Unmanaged, Dll)
- Microsoft Visual C# 2010 (Managed, Windows Form)

ClassLibrary.h

// ClassLibrary.h
#define DllExport _declspec(dllexport)
extern "C" DllExport int Sum(int, int);
extern "C" DllExport wchar_t getChar(void);
extern "C" DllExport wchar_t* getString(void);

#pragma once
int Sum(int, int);
wchar_t getChar(void);
wchar_t* getString(void);

ClassLibrary.cpp

#include "stdafx.h"
#include "ClassLibrary.h"

int Sum(int a, int b){return a + b;}
wchar_t getChar(){return L'ن';}
wchar_t* getString(){return L"امیرمهدی خادم آستانه";}

part of Form1.cs

[DllImport("c:\\ClassLibrary.dll", CharSet = CharSet.Unicode)]
[return : MarshalAs(UnmanagedType.I4)]
public static extern Int32 Sum(Int32 a, Int32 b);

[DllImport("c:\\ClassLibrary.dll", CharSet = CharSet.Unicode)]
public static extern char getChar();

[DllImport("c:\\ClassLibrary.dll", CharSet = CharSet.Unicode)]
