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.
