Salman,
please, read some tutorial texts on reference counting. 
Scott Meyers "Effective C++" and "More Effective C++" should help.
You obviously do not understand the concept of object sharing 
and multiple references. In regard to couple of your previous emails,
a little bit of tolerance and more friendly attitude would help.
