Yes, since there are no return values from constructors
this is where exceptions could be used.
Exceptions are, however, a real pain & I don't know
if CW supports them.
A Q&D way of handling this sort of thing is to define
an "isOk()" method for your class that can be called
-after- the constructor:
myObject x(param1, param2);
if (!x.isOk()) {
// report error creating object
}
