Hi Guy!
Comment ca va?
I'm not sure I understand your question...
To me a CRef is a temporary pointer to an XSI object.
If XSI or you delete the object, the the CRef should become invalid...
Imagine this code:
CRef oObj(!something valid!);
// oObj.IsValid() should return true
CValueArray oArgs(1);
oArgs[0] = CValue(oObj);
CValue oRtn;
Application().ExecuteCommand("DeleteObj", oArgs, oRtn);
//now
oObj.IsValid() should return false.
I might be really wrong here...
And of course this doesn't work in the scope of an operator!
Cheers,
Aloys

Hi,
while talking offline with Alan on some issue, I suddently had a doubt
regarding the persistence of CRef objects's references.
Thinking this is exactly one of the purposes of the CRef class, I still
would like to be 100% sure that it is guaranted that an object
referenced by a CRef object will persist at least as long as the CRef
object itself lifespan ?
Or is there any situation where a CRef object might become invalid
because the referenced object has been deleted ( by XSI, not the user ) ?
( are they 'reference counted' ? )
By object referenced by a CRef instance I dont only mean 'something' in
the 3d scene, but any instance of any derived class from CRef.
Andrew ?
