c++ - can't catch base of subclass.. must throw base

mmmm..

Ok, after reviewing all the c++ messages avail in web interface, I can see that
you guys are busy in all caps.

I have downloaded beta compiler, and if you do the equivalent of:

class Exception { };
class MyError : public Exception { };

try {
throw MyError( );
} catch (Exception& e) {
; // we never get here!!
}

You will find that you must actually throw an object of type Exception to find
your way to the catch.

Hmm, but it works for me: #include <stdio.h> class Exception { }; class MyError : public Exception { }; int main() { try { throw MyError( ); } catch (Exception& e) { printf("caught Exception\n"); } } Prints "caught Exception" as expected... bye, Christof -- http://cmeerw.org JID: cmeerw jabber.at mailto cmeerw at web.de ...and what have you contributed to the Net?

Hmm, but it works for me:

Must have been a configuration thing on my end with stlport.. Works for me too. Sorry. Richard
