Hi Luis,

Thank you for your response. I ran the test program and the given the
results are given below along with detailed System information and what
option i used to compile itk.

Itk compilation
---------------------
I have some doubts in this section.

CMake version: CMake 2.6-patch 4.

I selected the option Visual Studio 9 2008 Win64 before pressing the
configure button.

The current generator: Visual Studio 9 2008 Win64 (left bottom in
attached image itk_cmake.png)

But when i selected the advance view:

Build Name: Win32-vs9 (top of the image itk_cmake.png) To clear this, i
opened the cmakecache.txt (attached to this email) and it is written
"Build Name = Win32-vs9".

I thought when i use Visual Studio 9 2008 Win64 option the build name
would be Win64-vs9. I would like to clear this doubt. 
So, my Question is :
Is it correct to have Win32-vs9 in "Build Name" even after selecting
Visual Studio 9 2008 Win64 as "Current Generator"?

Microsoft visual studio 2008
---------------------
Configuration manager details: 
Active Solution Configuration: Debug
Active Solution Platform: x64

Test run details:
1. Program:
    unsigned long tt;
    std::cout << "size = " << sizeof(tt) << std::endl;
    tt  =  -1;
    std::cout << "tt = " << tt << std::endl; 
    output: size = 4; tt = 4294967295

2. Program:
    unsigned long long tt;
    std::cout << "size = " << sizeof(tt) << std::endl;
    tt  =  -1;
    std::cout << "tt = " << tt << std::endl; 
    output: size = 8; tt = 18446744073709551615 

I changed the configuration details:
--------------------------------------
Active Solution Configuration: Debug
Active Solution Platform: Win32

Test run details:
1. Program:
    unsigned long tt;
    std::cout << "size = " << sizeof(tt) << std::endl;
    tt  =  -1;
    std::cout << "tt = " << tt << std::endl; 
    output: size = 4; tt = 4294967295

2. Program:
    unsigned long long tt;
    std::cout << "size = " << sizeof(tt) << std::endl;
    tt  =  -1;
    std::cout << "tt = " << tt << std::endl; 
    output: size = 8; tt = 18446744073709551615 

For both Win32 and x64 i get the same result.
Unsigned long is 4 byte and unsigned long long is 8 byte.

I was a little confused after the result, so i searched for data type
ranges in msdn. Link below:
