I am not quite sure what you mean, but in any case you can forget about the 0 "return value" of the functions in the class definition. That's only a C++ notation for so-called pure virtual functions, nothing to do with return values.

Thanks.
there is an observer in the engine class CHTTPExampleEngine. and there are not the definition of these virtual functions in the class.
so these return values of these virtual functions are all 0.
is my understanding right?

They should be defined by the class that wants to act as an observer for this engine class. With the M-class the engine only specifies the interface through which it can provide information for the observer, it is the duty of the observer to make the actual implementation of these functions since it is the only one to know what it wants to do with the data.

virtual void ResponseStatusL(TInt aStatusCode, const TDesC& aStatusText) = 0;
virtual void ResponseReceivedL(const TDesC& aResponseBuffer) = 0;

they have not been defined.

hi,
i have a question, why the class MHTTPExampleEngineObserver has not been defined?

The mmp file should look something like:

SYSTEMINCLUDE   \epoc32\include
SYSTEMINCLUDE   \epoc32\include\http
SYSTEMINCLUDE   \epoc32\include\ecom

source file:

#include <MHTTPAuthenticationCallback.h>
#include <ecom.h>

Make file has to be re-generated after modifying the mmp file before generating the target.

i added the path of the directory in SYSTEMINCLUDE path of mmp file but stll problem exist...

Add the path of the directory to your mmp file under "Systeminclude" path.
If the path is defined in systeminclude path of mmp file, then there is no need to specify the sub-directory.

in an another application it is decleared simply as
#include <MHTTPAuthenticationCallback.h>
and it is working fine in that application...

ecom.h needs "ecom\" instead of "http\", but otherwise same story...

You find the exact locations of header files in the S60 SDK documentation, mostly. Just look closely for any subdirectories given in include lines.

now following error is coming
ecom.h can not be opened
cauthenticationfilterinterface.h line 15

Thanks. Now compare your include line with the one that I gave already in my earlier post:

#include <http\MHTTPAuthenticationCallback.h>

Do you see the difference? That's what I meant by giving the subdirectory in the include line.

brajesh1983 — Wed, 02 Jan 2008 08:34:00 +0100

i created a file a.h and a.cpp

//-----This is a.h----------------------------------//
#include <MHTTPAuthenticationCallback.h>
class A
{
public:
void Display();
};

//-----This is a.cpp----------------------------------//
void A::Display()
{
}

error is comming.

the file ' MHTTPAuthenticationCallback.h' can not be opened.
undefined identifier 'MHTTPTransactionCallback'

Can you please post the exact source line that you used to include that header file?
