I faced a problem when I wanted to change the content of a member variable in my script class.

This is my class:

class Foo
{
  int baz1;
  Bar@ baz2;
}

I can easily change value types in C++ by:

int* value = (int*)addressOfbaz1;
(*value) = 456;

But this doesn't work with object handles and I know why, but I don't know how I can alter the address that object handles are pointing to.

Shouldn't it be possible to do this?

Bar** ppBar = (Bar**) addressOfBaz2;

*ppBar = pToSomeOtherBarInstance;

Hey I didn't try that at all. Thanks for the reply. It's solved.

Just don't forget to properly update the reference count of the objects referred to by the handle. Otherwise you'll get memory leaks (if you forget to call Release()), or dangling pointers (if you forget to call AddRef()).
