Closing your eyes and saying "Abracadabra" will sometimes work. Other than that, you'll need to rephrase your question.

Hey what happend why you and other members on this thread got 1,maybe I can repair it with 5 vote.;)

It is something that happens a lot without sense, there should be some user of forum that hate some people here.
On the other hand... Thanks, but I don't care about the votes, I am far away less skilled as many other users so... If I really help someone my best reward is a simple "thanks" from asker.

I found the macro :
#define NAME(VAR) ( CString(#VAR) )
and then you can use it for getting any variable name at runtime:
CString s = NAME(m_sName);
If you don't know something it does not mean that it's not exist!

Don't you like the double quotes ", do you?

but don't you just know the name of the variable you handle when you pass it to the macro ?!

The same way as surrounding double quotes can.

Sure, but the nice thing about it is you can write a single macro that takes one argument
(a variable) and uses both its name and its value, making it easy to dump a lot of variables.

Of course, the above is the trick that makes the difference.
I hope the OP will realize it.

Can we use of this macro for other problems like find out exceptions on programs?;)

Sure!
I use it even to find a parking space for my car in the evening.

Take a look in http://www.codeproject.com/printing/[^] section here and read a bit. There is a lot of things that can answer you.
Is not for a dialog but I recommend you the articles of Roger Allen and Joseph M. Newcomer their artcles helped me a lot while doing my own printing.

have used edit control in dialog box.
I can get the entered string as
CEdit *ptrEdit = (CEdit*)GetDlgItem(IDC_EDITURL);
CString urlString;
ptrEdit->GetWindowText(urlString);
bool bDestination = PCHSEManagerInternal.IsDestinationReachable(urlEdit);
//above line is in MSDN
I do not know what is "PCHSEManagerInternal".
The following errors occured
error C2065: 'PCHSEManagerInternal' : undeclared identifier
error C2228: left of '.IsDestinationReachable' must have class/struct/union type
do I need to include any header file for this
please help me for this.

If you are using a MSDN example without taking care about what you are copying, it is totally logical that you have errors.
That "PCHSEManagerInternal" is a class that is being used in the example and, logically, if you didn't include the header that need that class your compiler complains at it makes. It can not know what it is, is the same scenario as if you create a class "CMyClass" and the you include "CMClass" the compiler won't recoginise it.
So...
Go another time to the web where you get that line, and READ the explanations and the whole code. Take special atention to the #includes and what the article/example say about that class. You may have to search for the whole class (*.cpp and *.h) when it is not an included component in VS headers

I have used edit control in dialog box.
I can get the entered string as
CEdit *ptrEdit = (CEdit*)GetDlgItem(IDC_EDITURL);
CString urlString;
ptrEdit->GetWindowText(urlString);
This 'urlString' contains web site address e.g. "http://www.google.com"
I want to validate this web site address. i.e. give me code which validates such string.
please help me for this.
