Re: about Exception
Hello!
Yes absolutely.
It seems to me that the code which actually is a MFC DLL is written in a
strange way
that cause this kind of problem.
I just created an empty MFC project using the wizard and now I could easily
use catch handlers that
you send me.
I can't understand how it's possible to write code that prevent using catch
handlers
like catch(CException ex)
As I mentioned before this CDataSource shouldn't be able to throw an
execption but
if this CDataSource doesn't throw who is then throwing because there is only
one statement within try block
and that is this CDataSource.Open
I must be able to find out what information this thrown exception is
Have you any good suggestion what I can do?
It's a C# asp.net application that is using this MFC DLL and
when the C# asp.net application catch the exception from this
CDataSource.Open
it says ProtectedMemory Error thats way I do want to catch this within MFC
instead
to get as much information as possible about the exception

Syntax errors are generally errors indicating an error in the way you are
using something.
Are you sure your code looks like the one I gave you earlier?

Hello!
When I use CException in the catch handler
I get compile error with this error message "syntax error : identifier
'CException'"
Have you any suggestion what I can do to use this CException
I have also tried to use other classes that are derived from this
CException
but I get the same compile error for these.
I must in some way get more information about this exception thta is
throw from this CDataSource.Open and that's way
I must use this CException class in the catch handler.

what is the exact error message? CException is included with afx.h
which gets included with any MFC include.

Hello!
For some reason will this DS.Open throw an exception because
If I write catch(...) insted
the code in the catch(...) will be executed
So therefore I must try to find out for what reason is this DS.Open
thowing an exception beacuse
it must do otherwise I shouldn't be able to be placed in catch handler
This DS i CDataSource.
The problem with my code is that if I write exactly as you have written
the compiler says "syntax error : identifier 'CException'"
try
{
hr = DS.Open(strtemp, &dbInit);
}
catch(CException *e)
{
TRACE1(_T("Caught it. %s"), e->GetErrorMessage());
e->Delete();
}
How you any solution to my problem ?

According to the documentation of CDataSource, the Open method doesn't
throw any exceptions.
Are you getting an exception at that line?!
if you are then maybe try this
try
{
hr = DS.Open(strtemp, &dbInit);
}
catch(CException *e)
{
TRACE1(_T("Caught it. %s"), e->GetErrorMessage());
e->Delete();
}

Hello!
DS is a CDataSource.
I tried to write catch(Exception ex)
but the compiler complains about the identifier Exception
I have also written #include <exception>
How should I write ?

Hello!
This works but I want to get some information about the exception.
how do I modify this catch(...) to get additional information
It depends on the type of DS. We don't know it since
you did not tell us. Consult the documentation of the
Open() method of DS.
