[fdo-dev] Standard exceptions handling practice

[Greg Boone]

I would write something like...

try
{
    // operation that throws exception derived
    // from standard ex. type std::exception
    bar();
}
catch ( FdoException* ex )
{
    throw FdoException::Create(
        NlsMsgGet(XYZ_123_FAIL_BAR, "bar() failed"), ex);
}
catch ( std::exception &e )
{
    FdoExceptionP cause = 
	
FdoException::Create((FdoString*)(FdoStringP(e.what())));
    throw FdoException::Create(
		NlsMsgGet(XYZ_123_FAIL_BAR, "bar() failed"), cause);
}

-----------------------------------------------------------^^^^^^^

I know it won't work, because FdoException::create() does not take
std::exception type.
So, this is also my question.
