Hai,
I have a small query regrading the application ie what is the difference between Service and Console Application.

Not as much as you would think.
Think of it this way, a Service is a Console application except that it has different security settings and is started by the Operating System rather than a user (normally anyway).
A Service should have NO user interface at all, where as a Console application could output text for the user to read.
The SCM (Service Control Manager) basically tells a Service when to START, STOP, PAUSE or CONTINUE, etc.

Sorry to correct you 
I said "A Service should have NO user interface at all", i.e SHOULD have no user interface.

Services themselves typically do not have a UI. Perhaps you are thinking of the SCM or a SCP.

A service is *most of the time* a console application. But not mandatory. This does not mean necessary that the service displays an user interface, but if the project was compiled with /subsystem:console or /subsystem:windows.
Other than this, a service application is registered in system as such, accepts certain control codes, and is managed by SCM (Service Control Manager).
One can write a service that can interact with the desktop and even display an user interface (although not recommended, sure), not only because a service *must* be a console application, but because this kind of application is intended to be not interactive, system managed, and perform a continuous "service" - hence the name - without user interface. However, a service can create hidden windows for special purpose messages, or use functions that require a message loop. Even COM uses special purpose windows from what I know, so indirectly creating, say, CoCreateInstance, in a service does not makes a service "window free".
A console application is what its name says, just an application compiled for and executed in a console window. Nothing more.

Hai,
I have a doubt regarding Windows Services whether In which level windows services are running ( Low , Kernel, Application )
Regards,
Chinna

Most Services are basically normal applications, they can be run as a specific user account or quite often as the 'LocalSystem' account.
There are obviously security issues running as LocalSystem, including the fact that you cannot access network shares easily (without impersonating another user).
It's not the Service which is either Kernel or User mode, it's the code itself, e.g. Most code will be User mode but things like EnterCriticalSection() can cause a switch to Kernel mode if necessary.

This question doesn't really make sense. For one, the OS need not be located in a contiguous memory range. Secondly, the core OS is in kernel space and the address would do you no good as you can’t access it from user mode. Thirdly, the OS is made up of many processes and the user space of each process is discrete. There are many more complexities but I'll stop here. Can you describe what you’re actually trying to achieve?

I think its _T("OS"), a literal string whose base address he wants to know :

I'm not convinced this is the case. Here's a quote: "i want to find memory address of my operating system". That doesn't sound like a string question to me!

Nah, I was just joking. (Perhaps you didn't note the joke icon in my post)

Add #include "StdAfx.h" to the file before all other includes.

Why i am geeting an error
"error C2146: syntax error : missing ';' before identifier 'xd_len'"
when including the header x25.h
|
|
|
|

maybe its because the definition of xd_len's type is not available...you may need to include some other headers....
