No it is not safe. That is the old style of casting. With that style I could
do something like this:
int x = 1;
DOM_Node n = (DOM_Node)x; // which you know is not right.
I suggest you use the following:
DOM_Entity domen = dynamic_cast<DOM_Entity>(node);
If it doesn't compile, it may be that the compiler is trying to tell you
that 'node' may NOT be a DOM_Entity type and you are doing an illegal cast.
Regarding the blank screen, in your example, if 'node' is not a DOM_Entity
type, you could be corrupting your screen memory.
